Shamol kuchi yoki shamol energiyasi ning ishlatilishi shamol ta'minlash uchun mexanik quvvat orqali shamol turbinalari burmoq elektr generatorlari uchun elektr quvvati. Shamol kuchi mashhur barqaror, yangilanadigan juda kichikroq quvvat manbai atrof muhitga ta'siri yonish bilan solishtirganda Yoqilg'i moyi.

Shamol ishlab chiqaradigan fermer xo'jaliklari bilan bog'langan ko'plab individual shamol turbinalaridan iborat elektr energiyasini uzatish tarmoq. Quruqlikdagi shamol bu arzon elektr energiyasi manbai bo'lib, u ko'mir yoki gaz zavodlari bilan raqobatdosh yoki ko'p joylarda raqobatdosh.^[2][3][4][5] Quruqlikdagi shamol elektr stantsiyalari landshaftga boshqa elektr stantsiyalariga qaraganda ko'proq ta'sir qiladi, chunki ular ko'proq erlarga tarqalishi kerak^[6][7] va zich aholidan uzoqroq joyda qurish kerak.^[8][7] Offshore shamol quruqlikdan vaga qaraganda barqarorroq va kuchliroqdir offshor fermer xo'jaliklari kamroq vizual ta'sirga ega, ammo qurilish va texnik xizmat ko'rsatish xarajatlari sezilarli darajada yuqori. Kichik quruqlikdagi shamol elektrostansiyalari tarmoqqa ozgina energiya etkazib berishi yoki tarmoqdan tashqari joylarda xavfsiz holatga keltirishi mumkin.^[9]

Shamol an vaqti-vaqti bilan energiya manbai bo'lishi mumkin emas jo'natildi so'rov bo'yicha; talabda.^[6] Mahalliy ravishda, bu beradi o'zgaruvchan quvvat, bu yildan-yilga mos keladi, ammo qisqa vaqt o'lchovlarida juda farq qiladi. Shuning uchun uni ishonchli quvvat bilan ta'minlash uchun boshqa quvvat manbalari bilan birgalikda ishlatish kerak. Ega bo'lish kabi quvvatni boshqarish usullari jo'natiladigan quvvat manbalari (ko'pincha gaz bilan ishlaydigan elektr stantsiyasi yoki gidroelektr energiyasi ), ortiqcha quvvati, geografik jihatdan taqsimlangan turbinalari, elektr energiyasini qo'shni hududlarga eksport qilish va import qilish, energiya saqlash, shamol ishlab chiqarish kam bo'lsa, talabni kamaytirish, ushbu muammolarni bartaraf etish uchun ishlatiladi.^[10][11] Mintaqadagi shamol energiyasining ulushi ortib borayotganligi sababli tarmoqni yangilash kerak bo'lishi mumkin.^[12][13] Ob-havo ma'lumoti elektr tarmog'ini yuzaga keladigan ishlab chiqarishdagi taxminiy o'zgarishlarga tayyor bo'lishiga imkon beradi.^[14][15][16]

Tarix

Charlz F. Brush elektr energiyasini ishlab chiqarishda ishlatiladigan 1888 yildagi shamol tegirmoni.

Shamol kuchi odamlar qo'ygan paytgacha ishlatilgan suzib yuradi shamolga. Shoh Xammurapi Kodeksi (miloddan avvalgi 1792 - 1750 yillar hukmronligi) mexanik energiya ishlab chiqarish uchun shamol tegirmonlarini eslatib o'tgan.^[22] Donni maydalash va suvni haydash uchun ishlatiladigan shamol bilan ishlaydigan mashinalar, shamol tegirmoni va shamol nasosi, hozirgi paytda ishlab chiqilgan Eron, Afg'oniston va Pokiston 9-asrga kelib.^[23][24] Shamol kuchi keng tarqaldi va tez oqim oqimlari qirg'og'ida cheklanmagan, yoki keyinchalik yoqilg'i manbalarini talab qilgan. Shamol bilan ishlaydigan nasoslar suvni quritdi Niderlandiyaning polderlari va kabi qurg'oqchil mintaqalarda Amerikaning o'rta-g'arbiy qismi yoki Avstraliyaning tashqi tomoni, shamol nasoslari chorva mollari va bug 'dvigatellarini suv bilan ta'minladi.

Elektr energiyasini ishlab chiqarish uchun ishlatiladigan birinchi shamol tegirmoni qurilgan Shotlandiya 1887 yil iyulda tomonidan Prof Jeyms Blyt ning Anderson kolleji, Glasgow (kashshofi Strathlyd universiteti ).^[25] Blythning balandligi 10 metr (33 fut), mato bilan suzilgan shamol turbinasi uning dam olish uyining bog'iga o'rnatildi Marykirk yilda Kincardineshire va zaryadlash uchun ishlatilgan akkumulyatorlar frantsuz tomonidan ishlab chiqilgan Camille Alphonse Faure, yozgi uyning yoritilishini ta'minlash uchun,^[25] Shunday qilib, bu elektr energiyasini shamol energiyasi bilan ta'minlaydigan dunyodagi birinchi uyga aylandi.^[26] Blyt asosiy ko'chani yoritish uchun Marykirk aholisiga ortiqcha elektr energiyasini taklif qildi, ammo ular elektr energiyasini "shaytonning ishi" deb o'ylab, taklifni rad etishdi.^[25] Keyinchalik u mahalliy Lunatik boshpana, shifoxona va dispanserni favqulodda quvvat bilan ta'minlash uchun shamol turbinasini qurgan bo'lsa ham. Montrose, ixtiro hech qachon haqiqatan ham qo'lga kiritilmagan, chunki texnologiya iqtisodiy jihatdan foydali deb hisoblanmagan.^[25]

Atlantika bo'ylab Klivlend, Ogayo shtati, 1887-1888 yil qishda kattaroq va og'ir muhandislik mashinasi ishlab chiqilgan va qurilgan Charlz F. Brush.^[27] Bu uning muhandislik kompaniyasi tomonidan o'z uyida qurilgan va 1886 yildan 1900 yilgacha faoliyat yuritgan.^[28] Brush shamol turbinasi 17 metr (56 fut) diametrli rotorga ega edi va 18 metr (59 fut) minoraga o'rnatildi. Bugungi me'yorlar bo'yicha katta bo'lishiga qaramay, mashina atigi 12 kVt quvvatga ega edi. Bog'langan dinamo batareyalarni zaryad qilish yoki 100 tagacha ishlash uchun ishlatilgan akkor lampalar, uchta yoy chiroqlari va Brush laboratoriyasida turli xil motorlar.^[29]

Elektr energetikasining rivojlanishi bilan shamol energetikasi markazlashtirilgan ishlab chiqariladigan energiyadan uzoq binolarni yoritish uchun yangi dasturlarni topdi. 20-asr davomida parallel yo'llar fermer xo'jaliklari yoki turar joylar uchun mos bo'lgan kichik shamol stantsiyalarini ishlab chiqardi. The 1973 yilgi neft inqirozi Daniya va Qo'shma Shtatlarda olib borilgan tergovni boshlagan, natijada elektr energiyasidan masofadan foydalanish uchun elektr tarmoqlariga ulanishi mumkin bo'lgan katta hajmdagi shamol generatorlari. 2008 yilga kelib AQShning o'rnatilgan quvvati 25,4 gigavattga etdi, 2012 yilga kelib esa 60 gigavattni tashkil etdi.^[30] Hozirgi kunda shamol energiyasi bilan ishlaydigan generatorlar gigavatt kattaligiga qadar bo'lgan izolyatsiya qilingan joylarda akkumulyator batareyalarini zaryadlash uchun kichik stantsiyalar orasidagi har qanday o'lchamdagi diapazonda ishlaydi. offshor shamol elektr stantsiyalari milliy elektr tarmoqlarini elektr energiyasi bilan ta'minlaydigan.

Shamol energiyasi

Yer sathidan 100 m balandlikda shamol tezligining global xaritasi.^[31]

Filippin shamol sathi zichligi xaritasi sirt sathidan 100 m balandlikda.^[31]

2002 yil davomida Kolorado shtatidagi Li Ranch inshootida shamol tezligini (qizil) va energiyani (ko'k) taqsimlash. Gistogrammada o'lchangan ma'lumotlar ko'rsatilgan, egri esa xuddi shu o'rtacha shamol tezligi uchun Rayleigh modeli taqsimoti.

Shamol energiyasi kinetik energiya harakatdagi havo, shuningdek deyiladi shamol.Hayoliy sirt orqali maydonning umumiy shamol energiyasi A vaqt davomida t bu:

${ displaystyle E = { frac {1} {2}} mv ^ {2} = { frac {1} {2}} (Avt rho) v ^ {2} = { frac {1} {2 }} At rho v ^ {3},}$^[32]

qayerda r bo'ladi havo zichligi; v bu shamol tezlik; Avt bu havoning o'tishi A (bu shamol yo'nalishiga perpendikulyar deb hisoblanadi); Avtror shuning uchun massa m "A" dan o'tish. ½ rv² birlik hajmiga qarab harakatlanuvchi havoning kinetik energiyasi.

Quvvat - bu birlik vaqtidagi energiya, shuning uchun shamol kuchi yoqiladi A (masalan, shamol turbinasining rotor maydoniga teng):

${ displaystyle P = { frac {E} {t}} = { frac {1} {2}} A rho v ^ {3}.}$^[32]

Shunday qilib, ochiq havo oqimidagi shamol kuchi mutanosib uchun uchinchi kuch shamol tezligi; shamol tezligi ikki baravar oshganda mavjud quvvat sakkiz baravar ko'payadi. Shuning uchun tarmoq elektr energiyasi uchun shamol turbinalari shamolning katta tezligida ayniqsa samarali bo'lishi kerak.

Shamol - bu Yer yuzasi bo'ylab yuqori bosim va past bosim joylari ta'sirida bo'lgan havo harakati.^[33]Shamolning global kinetik energiyasi o'rtacha 1,50 MJ / m ni tashkil etdi² 1979 yildan 2010 yilgacha 1,31 MJ / m² 1,70 MJ / m bo'lgan Shimoliy yarim sharda² janubiy yarim sharda. Atmosfera issiqlik dvigatelining vazifasini bajaradi, yuqori haroratlarda issiqlikni yutadi, past haroratlarda issiqlikni chiqaradi. Jarayon shamol kinetik energiyasini 2,46 Vt / m tezlikda ishlab chiqarish uchun javobgardir² atmosferaning ishqalanish tarqalishiga qarshi aylanishini ta'minlash.^[34]

Orqali shamol resurslarini baholash global miqyosda, mamlakatlar yoki mintaqalar bo'yicha yoki ma'lum bir sayt uchun shamol energetikasi potentsialini taxmin qilish mumkin. Shamol energetikasi salohiyatini global baholash Global Shamol Atlasi tomonidan taqdim etilgan Daniya Texnik universiteti bilan hamkorlikda Jahon banki.^[31][35][36]"Statik" shamol manbai atlaslaridan farqli o'laroq, shamol tezligi va quvvat zichligi bo'yicha bir necha yillar davomida o'rtacha hisob-kitoblar, masalan Qayta tiklanadigan manbalar.ninja soat tezligi bo'yicha shamol turbinasining turli xil modellaridan quvvat tezligi va tezligi o'zgaruvchan simulyatsiyalarni taqdim etish.^[37] Shamol resurslari potentsialini batafsilroq, saytga tegishli baholashni mutaxassis tijorat provayderlaridan olish mumkin va ko'plab yirik shamol ishlab chiqaruvchilar o'zlarining modellashtirish imkoniyatlarini saqlab qoladilar.

Shamoldan olinadigan iqtisodiy jihatdan olinadigan quvvatning umumiy miqdori hozirgi barcha manbalardan foydalaniladigan inson kuchidan ancha ko'pdir.^[38]Aksel Kleidon Maks Plank instituti Germaniyada, atmosferada harorat farqi yaratib, shamollarni harakatga keltiruvchi kirib keladigan quyosh radiatsiyasidan boshlab, shamol energiyasi qancha ekanligi to'g'risida "yuqoridan pastga" hisob-kitobni amalga oshirdi. U 18 TVtdan 68 TVtgacha olinishi mumkin degan xulosaga keldi.^[39]

Kristina Archer va Mark Z. Jakobson Kleidondan farqli o'laroq shamol tezligini aniq o'lchashga asoslangan va quruqlik va dengiz ustidan 100 metr balandlikda 1700 TVt shamol kuchi borligini aniqlagan "pastdan yuqoriga" taxminini taqdim etdi. Buning ichida "72 dan 170 TVtgacha amaliy va iqtisodiy jihatdan raqobatbardosh usulda olinishi mumkin".^[39] Keyinchalik ular 80 TVtni taxmin qilishdi.^[40] Biroq, tadqiqot Garvard universiteti taxminan 1 vatt / m² o'rtacha va 2–10 MVt / km² keng miqyosli shamol elektr stantsiyalarining quvvati, bu global shamol resurslarining umumiy hisob-kitoblari taxminan 4 marta juda yuqori ekanligini anglatadi.^[41]

Shamolning kuchi har xil va ma'lum bir joy uchun o'rtacha qiymat shamol turbinasi u erda ishlab chiqarishi mumkin bo'lgan energiya miqdorini ko'rsatmaydi.

Istiqbolli shamol energetikasi uchastkalarini baholash uchun ehtimol taqsimot funktsiyasi ko'pincha kuzatilgan shamol tezligi ma'lumotlariga mos keladi.^[42] Turli xil joylarda turli xil shamol tezligi taqsimoti bo'ladi. The Vaybull model ko'plab joylarda shamolning soatlik / o'n daqiqalik tezligini haqiqiy taqsimlanishini yaqqol aks ettiradi. Vaybul omil ko'pincha 2 ga yaqin va shuning uchun a Rayleigh taqsimoti unchalik aniq bo'lmagan, ammo sodda model sifatida foydalanish mumkin.^[43]

Shamol elektr stantsiyasi - bu guruh shamol turbinalari elektr energiyasini ishlab chiqarish uchun foydalaniladigan joyda. Katta shamol elektr stantsiyasi kengaytirilgan hududga taqsimlangan bir necha yuz individual shamol turbinalaridan iborat bo'lishi mumkin. Shamol turbinalari har bir MVt uchun 0,3 gektar erdan foydalanadi,^[56] ammo turbinalar orasidagi er qishloq xo'jaligi yoki boshqa maqsadlarda ishlatilishi mumkin. Masalan, Gansu shamol zavodi, dunyodagi eng katta shamol stansiyasi, bir necha ming turbinaga ega. Shamol elektr stantsiyasi ham offshorda joylashgan bo'lishi mumkin.

Deyarli barcha yirik shamol turbinalari bir xil dizaynga ega - baland trubkali minora tepasida natselga bog'langan, uchta pichoqli shamol rotoriga ega bo'lgan gorizontal o'qli shamol turbinasi.

Shamol elektr stantsiyasida alohida turbinalar o'rta kuchlanishli (ko'pincha 34,5 kV) quvvat yig'ish tizimi bilan o'zaro bog'liqdir^[57] va aloqa tarmog'i. Umuman olganda, har bir turbinaning o'rtasida 7D (shamol turbinasining rotor diametridan 7 baravar ko'p) masofa o'rnatildi.^[58] Substansiyada ushbu o'rtacha kuchlanishli elektr toki kuchlanish bilan kuchaytiriladi transformator yuqori voltajga ulanish uchun elektr energiyasini uzatish tizim.^[59]

Jeneratör xususiyatlari va barqarorligi

Induksion generatorlar 1980 va 1990 yillarda shamol energetikasi loyihalari uchun tez-tez ishlatib turilgan, talab etiladi reaktiv quvvat uchun hayajon, shuning uchun elektr podstansiyalari shamol energiyasini yig'ish tizimlarida ishlatiladiganlar juda ko'pdir kondansatör uchun banklar quvvat omilini tuzatish. Shamol turbinasi generatorlarining har xil turlari uzatish tarmoqlarining buzilishi paytida o'zlarini turlicha tutishadi, shuning uchun uzatish tizimlari operatorlari tomonidan tizim buzilishlari paytida taxmin qilinadigan barqaror harakatni ta'minlash uchun yangi shamol elektr stantsiyasining dinamik elektromexanik xususiyatlarini keng modellashtirish talab etiladi (qarang. shamol energetikasi dasturi ). Xususan, induksion generatorlar bug 'yoki gidroturbin bilan harakatlanadigan sinxron generatorlardan farqli o'laroq nosozliklar paytida tizim kuchlanishini ushlab tura olmaydi.

Induksion generatorlar hozirgi turbinalarda ishlatilmaydi. Aksincha, aksariyat turbinalar turbina generatori va kollektor tizimi o'rtasida qisman yoki to'liq miqyosli quvvat konvertori bilan birlashtirilgan o'zgaruvchan tezlikni ishlab chiqaruvchilardan foydalanadi, ular odatda tarmoqni o'zaro bog'lash uchun ko'proq kerakli xususiyatlarga ega va Past kuchlanish orqali o'tish - imkoniyatlar.^[60] Zamonaviy tushunchalardan ham foydalaniladi ikki marta oziqlanadigan elektr mashinalari to'liq miqyosli konvertorlar bilan qisman shkalali konvertorlar yoki sincap kafesli indüksiyon generatorlari yoki sinxron generatorlar (doimiy va elektr quvvati bilan).^[61]

Bunga quyidagilar kiradi quvvat omili, ning barqarorligi chastota va tizim buzilishi paytida shamol elektr stantsiyalarining dinamik harakati.^[62][63]

Offshore shamol energiyasi

Dunyo bo'yicha ikkinchi to'liq ko'lamli suzuvchi shamol turbinasi (va avval og'ir yuk ko'taruvchi kemalardan foydalanmasdan o'rnatiladi), WindFloat, nominal quvvatda (2 MVt) dengizdan 5 km uzoqlikda ishlaydi. Póvoa de Varzim, Portugaliya

Dengizdagi shamol energetikasi deganda, katta miqdordagi suv havzalarida elektr energiyasini ishlab chiqarish uchun shamol elektr stantsiyalari qurilishi tushuniladi. Ushbu qurilmalar ushbu joylarda mavjud bo'lgan va landshaftga nisbatan kamroq estetik ta'sir ko'rsatadigan tez-tez va kuchli shamollardan foydalanishi mumkin. Biroq, qurilish va texnik xizmat ko'rsatish xarajatlari ancha yuqori.^[64][65]

Simens va Vestalar dengiz shamollari uchun etakchi turbinalarni etkazib beruvchilardir. Osted, Vattenfall va E.ON etakchi offshor operatorlari hisoblanadi.^[66] 2010 yil oktyabr oyidan boshlab, asosan Shimoliy Evropada 3,16 GVt quvvatga ega shamol energetikasi quvvati ishga tushirildi. Dengizdagi shamol energetikasining quvvati 2020 yilga qadar butun dunyo bo'ylab jami 75 GVt ga etishi kutilmoqda va bu muhim hissadir Xitoy va AQSh.^[66] Buyuk Britaniyaning offshor shamol energetikasiga kiritgan sarmoyalari natijasida 2012-2017 yillarda ko'mirdan energiya manbai sifatida foydalanish tez pasayib ketdi, shuningdek, 2017 yilda tabiiy gazdan energiya manbai sifatida foydalanish kamayib ketdi.^[67]

2012 yilda Evropaning 10 ta davlatidagi 55 ta offshor shamol stansiyalaridagi 1662 ta turbinalar 18 TVt soat ishlab chiqardi, bu deyarli besh million xonadonni elektr bilan ta'minlash uchun etarli.^[68] 2018 yil sentyabr oyidan boshlab Walney kengaytmasi ichida Birlashgan Qirollik dunyodagi eng yirik shamol elektr stantsiyasi bo'lib, 659 ga teng MW.^[69]

Shamol kuchi Serbiya

A shamol energetikasi, individual turbinalar o'rtacha kuchlanish (odatda 34,5 kV) quvvat yig'ish tizimi va aloqa tarmog'i bilan o'zaro bog'liqdir. Substansiyada ushbu o'rta kuchlanishli elektr toki yuqori voltajga ulanish uchun transformator bilan kuchlanishda oshiriladi elektr energiyasini uzatish tizim.

Ishlab chiqarilgan quvvatni (ko'pincha uzoq) bozorlarga etkazish uchun elektr uzatish liniyasi talab qilinadi. Dengiz stantsiyasi uchun bu dengiz osti kabelini talab qilishi mumkin. Yangi yuqori voltli liniyani qurish faqat shamol manbai uchun juda qimmatga tushishi mumkin, ammo shamol joylari an'anaviy yoqilg'i ishlab chiqarish uchun allaqachon o'rnatilgan liniyalardan foydalanishi mumkin.

Qo'shma Shtatlarda shamol energetikasi tarmog'iga integratsiyalashishning dolzarb muammolaridan biri shamolni elektr stantsiyalaridan, odatda mamlakatning o'rtalarida joylashgan aholi kam bo'lgan shtatlarda shamol bo'lishi sababli yuqori darajaga etkazish uchun yangi elektr uzatish liniyalarini yaratish zarurati hisoblanadi. odatda aholi zichligi yuqori bo'lgan sohillarda yuk joylari. Uzoq joylarda joylashgan elektr uzatish liniyalari katta miqdordagi energiyani tashish uchun mo'ljallanmagan.^[78] Elektr uzatish liniyalari tobora uzoqlashib borayotganligi sababli, elektr uzatish bilan bog'liq yo'qotishlar ko'payib boradi, chunki pastki uzunlikdagi yo'qotish rejimi kuchayadi va uzunlikning ko'payishi bilan yo'qotishning yangi usullari ahamiyatsiz bo'lib qoladi, bu katta yuklarni katta masofalarga olib o'tishni qiyinlashtiradi.^[79] Biroq, shtat va mahalliy hukumatlarning qarshiligi yangi elektr uzatish liniyalarini qurishni qiyinlashtirmoqda. Elektr energiyasini etkazib berishning ko'p davlatli loyihalari arzon elektr energiyasini eksport qilish narxlarning oshishiga olib kelishi mumkinligidan qo'rqib, arzon elektr energiyasi stavkalari bo'lgan davlatlar tomonidan qo'llab-quvvatlanmaydi. 2005 yilda qabul qilingan energetika to'g'risidagi qonunda Energetika departamentiga elektr uzatish loyihalarini tasdiqlash huquqi berilgan bo'lib, ular harakat qilishdan bosh tortgan, ammo ushbu vakolatdan foydalanishga urinishdan so'ng, Senat ushbu idorani haddan tashqari tajovuzkor deb e'lon qildi.^[78] Yana bir muammo shundaki, shamol kompaniyalari yangi fermer xo'jaligining elektr uzatish quvvati ishlab chiqarish quvvatidan past ekanligini bilib olishadi, chunki qayta tiklanadigan energetikani o'rnatishni rag'batlantirish bo'yicha federal kommunal qoidalar oziqlantiruvchi liniyalarning faqat minimal standartlarga javob berishiga imkon beradi. Bular hal qilinishi kerak bo'lgan muhim masalalardir, chunki elektr uzatish quvvati ishlab chiqarish quvvatiga to'g'ri kelmasa, shamol elektr stantsiyalari o'z imkoniyatlaridan pastroq ishlab chiqarishga yoki umuman ishlashni to'xtatishga majbur bo'ladilar. qisqartirish. Garchi bu potentsial qayta tiklanadigan avlodni ishga solinmaganligiga olib keladigan bo'lsa-da, bu tarmoqning haddan tashqari yuklanishini yoki ishonchli xizmatga xavf tug'dirishini oldini oladi.^[80]

Jahonda shamol ishlab chiqarish quvvati 2000 yildan 2006 yilgacha to'rt barobardan ziyod oshdi va taxminan har 3 yilda ikki baravarga oshdi.Qo'shma Shtatlar shamol elektr stantsiyalarining kashshoflari edi 1980-yillarda va 1990-yillarda o'rnatilgan quvvat bilan dunyoga etakchilik qildi. 1997-yilda Germaniyada o'rnatilgan quvvat AQSh-dan oshib ketdi va 2008-yilda Qo'shma Shtatlar tomonidan quvib chiqarilgunga qadar yetakchilik qildi. Xitoy 2000-yillarning oxirlarida shamol qurilmalarini jadal kengaytirmoqda. va 2010 yilda Qo'shma Shtatlardan o'tib dunyo etakchisiga aylandi. 2011 yilga kelib dunyoning 83 mamlakati tijorat asosida shamol energiyasidan foydalanmoqda.^[20]

Shamol ishlab chiqarishi mumkin bo'lgan elektr energiyasining haqiqiy miqdori quyidagini ko'paytirish orqali hisoblanadi plita sig'imi tomonidan imkoniyatlar omili Bu uskunalar va joylashuvga qarab farq qiladi, shamol inshootlari uchun quvvat koeffitsientlarini baholash 35% dan 44% gacha.^[84]

Dunyo bo'ylab o'rnatilgan shamol energetikasi quvvati prognozi^[55][87]

Tashqi video
Mamlakatlar bo'yicha shamol energetikasining o'sishi, 2005-2020 yillar

2014 yilda shamol energetikasi yangi rekordlarni o'rnatdi - 50 GVt dan ortiq yangi quvvat o'rnatildi. Yana bir rekordchi yil 2015 yilda sodir bo'ldi, bozorning yillik o'sishi 22 foizni tashkil etdi, natijada 60 GVt belgi o'tdi.^[88] 2015 yilda Evropadagi va Shimoliy Amerikadagi an'anaviy bozorlardan tashqarida barcha yangi shamol energiyasining yarmiga yaqini qo'shildi. Bu asosan Xitoy va Hindistondagi yangi qurilishlardan edi. Shamol energetikasi bo'yicha global kengash (GWEC) ko'rsatkichlari shuni ko'rsatadiki, 2015 yilda o'rnatilgan quvvat quvvati 63 GVt dan oshib, shamolning umumiy o'rnatilgan quvvati 2006 yildagi 74 GVt ga nisbatan 432,9 GVt ga etdi. Iqtisodiy ahamiyati jihatidan shamol energetikasi sektoriga aylandi investitsiyalarning umumiy hajmiga etadigan energiya bozorlaridagi muhim o'yinchilar AQSH$ 329 mlrd (€ 296,6 mlrd.), 2014 yilga nisbatan 4 foizga o'sdi.^[A][89]

Garchi shamol energetikasi ta'sirlangan global moliyaviy inqiroz 2009 va 2010 yillarda GWEC shamol energetikasining o'rnatilgan quvvati 2020 yil oxiriga qadar 792,1 GVtni tashkil etadi deb taxmin qilmoqda.^[88] va 2050 yil oxiriga qadar 4042 GVt.^[90] Shamol energetikasini ishga tushirish hajmining ko'payishi kutilayotgan qayta tiklanadigan elektr energiyasining rekord darajada past narxlari bilan birga olib borilmoqda. Ba'zi hollarda quruqlikdagi shamol elektr energiyasini ishlab chiqarishning eng arzon variantidir va xarajatlar pasayishda davom etmoqda. Keyingi bir necha yil ichida quruqlikdagi shamol uchun shartnoma narxlari hozirda 30 AQSh dollari / MVt / soatga teng.

Evropa Ittifoqida 2015 yilda barcha yangi ishlab chiqarish quvvatlarining 44% shamol energetikasiga to'g'ri keldi; shu davrda sof qazilma yoqilg'ining quvvat hajmi pasaygan.^[83]

Imkoniyatlar omili

Shamol tezligi doimiy emasligi sababli, shamol xo'jaligi yillik energiya ishlab chiqarish hech qachon generator yorlig'i reytinglari yig'indisining yil ichidagi umumiy soatlarga ko'paytirilishi kabi bo'lmaydi. Bir yillik real unumdorlikning ushbu nazariy maksimal darajaga nisbati deyiladi imkoniyatlar omili. Oddiy quvvat omillari 15-50% ni tashkil qiladi; diapazonning yuqori qismidagi qiymatlarga qulay joylarda erishiladi va bu shamol turbinasi dizayni yaxshilanishi bilan bog'liq.^[91][92][B]

Onlayn ma'lumotlar ba'zi joylar uchun mavjud va quvvat koeffitsientini yillik ishlab chiqarish hajmidan hisoblash mumkin.^[93][94] Masalan, Germaniya bo'ylab 2012 yil davomida shamol energetikasining o'rtacha quvvat koeffitsienti 17,5% dan ozroqni tashkil etdi (45,867 GVt · soat / yil / (29,9 GVt × 24 × 366) = 0,1746),^[95] va Shotlandiya shamol elektr stantsiyalari uchun quvvat koeffitsienti 2008-2010 yillarda o'rtacha 24% ni tashkil etdi.^[96]

Yoqilg'i ishlab chiqaradigan zavodlardan farqli o'laroq, quvvat koeffitsienti bir nechta parametrlarga ta'sir qiladi, shu jumladan maydonda shamolning o'zgaruvchanligi va o'lchamlari generator turbinaning supurilgan maydoniga nisbatan. Kichik generator arzonroq bo'ladi va yuqori quvvat koeffitsientiga erishadi, lekin kamroq ishlab chiqaradi elektr energiyasi (va shuning uchun kamroq foyda) yuqori shamollarda. Aksincha, katta generator ko'proq xarajat talab qiladi, lekin qo'shimcha quvvat ishlab chiqaradi va turiga qarab, mumkin tokcha past shamol tezligida. Shunday qilib, taxminan 40-50% gacha bo'lgan optimal quvvat koeffitsienti maqsad qilingan.^[92][97]

AQSh Energetika vazirligi tomonidan chop etilgan 2008 yilda o'tkazilgan tadqiqotlar shuni ta'kidladiki, yangi shamol qurilmalarining quvvat koeffitsienti texnologiya yaxshilanishi bilan ortib bormoqda va kelajakdagi quvvat omillari uchun yanada takomillashtirishni rejalashtirgan.^[98] 2010 yilda bo'lim yangi shamol turbinalarining quvvati koeffitsientini 2010 yilda 45% deb baholadi.^[99] AQShda shamol ishlab chiqarish uchun o'rtacha yillik quvvat koeffitsienti 2010-2015 yillarda 29,8% dan 34% gacha o'zgargan.^[100]

Penetratsiya

Shamoldan kelib chiqadigan asosiy energiya ulushi, 2019 yil^[102]

Shamol energiyasining kirib borishi - bu umumiy ishlab chiqarish bilan taqqoslaganda shamol tomonidan ishlab chiqariladigan energiyaning ulushi. 2018 yil oxirida shamol energiyasining butun dunyo bo'ylab elektr energiyasidan foydalanishdagi ulushi 4,8% ni tashkil etdi,^[103] 2015 yilda 3,5% dan.^[104][105]

Shamol penetratsiyasining umumiy qabul qilingan maksimal darajasi yo'q. Muayyan narsaning chegarasi panjara mavjud ishlab chiqaruvchi zavodlarga, narxlash mexanizmlariga, quvvatiga bog'liq bo'ladi energiya saqlash, talabni boshqarish va boshqa omillar. O'zaro bog'langan elektr tarmog'i allaqachon o'z ichiga oladi zaxira ishlab chiqarish va uzatish hajmi jihozlarning ishdan chiqishiga yo'l qo'yish. Ushbu zaxira quvvati, shuningdek, shamol stantsiyalari tomonidan ishlab chiqarilayotgan turli xil elektr energiyasini ishlab chiqarishni qoplashga xizmat qilishi mumkin. Tadqiqotlar shuni ko'rsatdiki, yiliga elektr energiyasini iste'mol qilishning 20% ​​minimal qiyinchilik bilan qo'shilishi mumkin.^[106] Ushbu tadqiqotlar ma'lum darajada geografik jihatdan tarqalgan shamol elektr stantsiyalari joylashgan joylar uchun qilingan jo'natiladigan energiya yoki gidroenergetika saqlash hajmi, talabni boshqarish va kerak bo'lganda elektr energiyasini eksport qilishga imkon beradigan katta tarmoq bilan o'zaro bog'liq. 20% darajadan tashqari, texnik cheklovlar kam, ammo iqtisodiy natijalar yanada muhimroq bo'ladi. Elektr tarmoqlari shamol ishlab chiqarishning keng ko'lamda kirib borishini tizim barqarorligi va iqtisodiyotiga ta'sirini o'rganishda davom etmoqda.^{[C][107][108][109]}

Shamol energiyasining kirib borishi ko'rsatkichi har xil vaqt uchun belgilanishi mumkin, lekin ko'pincha har yili keltirilib turiladi. Shamoldan har yili 100% olish uchun uzoq muddatli saqlash yoki sezilarli darajada saqlanishi mumkin bo'lgan boshqa tizimlar bilan o'zaro bog'liqlikni talab qiladi. Shamol oylik, haftalik, kunlik yoki soatlik, yoki undan kam miqdordagi hisobda, 100% yoki undan ko'pini ishlatishi mumkin, qolgan qismi esa saqlanib yoki eksport qilinadi. Keyinchalik mavsumiy sanoat yuqori shamol va kam foydalanish vaqtidan foydalanishi mumkin, masalan, shamol chiqishi odatdagi talabdan oshib ketishi mumkin bo'lgan tunda. Bunday sanoat tarkibiga kremniy, alyuminiy,^[110] po'lat yoki tabiiy gaz va vodorod va 100% energiya olish uchun kelajakda uzoq muddatli saqlashdan foydalanadi o'zgaruvchan qayta tiklanadigan energiya.^[111][112] Uylarni qo'shimcha ravishda elektr energiyasini talabga binoan qabul qilish uchun dasturlash mumkin, masalan, suv isitgich termostatlarini masofadan turib yoqish orqali.^[113]

O'zgaruvchanlik

Shamol turbinalari odatda shamolli joylarda o'rnatiladi. Rasmda shamol kuchi Ispaniyada generatorlar, an yaqinida Osborne buqasi.

Shamol kuchi o'zgaruvchan bo'lib, past shamol davrida uni boshqa quvvat manbalari bilan almashtirish kerak. Hozirgi vaqtda elektr uzatish tarmoqlari boshqa avlod zavodlarining uzilishlari va elektr energiyasiga bo'lgan ehtiyojning kunlik o'zgarishi bilan kurashmoqda, ammo o'zgaruvchanligi vaqti-vaqti bilan quvvat manbalari Masalan, shamol energetikasi odatdagi elektr energiyasini ishlab chiqaradigan stansiyalarga qaraganda tez-tez uchraydi, ular ishga tushirilishi rejalashtirilgan paytda o'zlarining yorliqlarini 95 foizga etkazib berishlari mumkin.

Shamol energiyasidan ishlab chiqarilgan elektr energiyasi bir necha xil vaqt jadvallarida juda o'zgaruvchan bo'lishi mumkin: soatlik, kunlik yoki mavsumiy. Yillik farq ham mavjud, ammo unchalik katta ahamiyatga ega emas. Bir zumda elektr energiyasini ishlab chiqarish va iste'mol qilish tarmoq barqarorligini saqlash uchun muvozanatda qolishi kerakligi sababli, bu o'zgaruvchanlik katta miqdordagi shamol energiyasini tarmoq tizimiga kiritish uchun katta qiyinchiliklarga olib kelishi mumkin. Intervalgacha va noaniqlikjo'natiladigan shamol energiyasini ishlab chiqarish tabiati tartibga solish xarajatlarini ko'paytirishi mumkin operatsion zaxira va (yuqori penetratsion darajalarda) allaqachon mavjud bo'lgan o'sishni talab qilishi mumkin energiya talabini boshqarish, yukni to'kish, saqlash echimlari yoki tizimning o'zaro aloqasi HVDC kabellar.

Yirik yoqilg'i yoqilg'isi ishlab chiqaruvchi agregatlardagi yuk va zaxiradagi dalgalanmalar shamol ishlab chiqarishining o'zgaruvchanligini qoplash uchun ko'paytirilishi mumkin bo'lgan zaxira quvvatini talab qiladi.

Hozirgi vaqtda katta shamolga ega bo'lgan tarmoq tizimlari ulardan foydalanish chastotasining ozgina ko'payishini talab qilmoqda tabiiy gaz shamol bo'lmasa elektr energiyasining yo'qolishini oldini olish uchun zaxira elektr stantsiyalarini yigirish. Shamol kuchi past bo'lgan holda, bu kamroq muammo.^{[114][115][116]}

GE ishlab chiqarilishi 60 soniyasiga teng bo'lgan elektromobilning akkumulyatoriga o'xshash batareyali prototipli shamol turbinasini o'rnatdi. Kichkina quvvatga qaramay, quvvat chiqishi 15 daqiqaga mo'ljallangan prognozga mos kelishini kafolatlashning o'zi kifoya, chunki akkumulyator to'liq chiqishni ta'minlash o'rniga farqni yo'q qilish uchun ishlatiladi. Muayyan holatlarda shamolning kuchayib borishi 20 dan 30 gacha yoki 40 foizgacha ko'tarilishi mumkin. Batareyaning narxini talabga binoan portlash quvvatini sotish va gaz zavodlarining zaxira ehtiyojlarini kamaytirish orqali olish mumkin.^[117]

Buyuk Britaniyada 2008 yildan 2010 yilgacha 124 ta alohida holat bo'lib, mamlakatning shamol ishlab chiqarish quvvati o'rnatilgan quvvatning 2 foizidan kamrog'iga tushgan.^[118] Daniyaning shamol energetikasi to'g'risidagi hisobotda ta'kidlanishicha, ularning shamol energetikasi tarmog'i 2002 yil davomida 54 kunlik o'rtacha talabning 1 foizidan kamini ta'minlagan.^[119] Shamol energetikasi himoyachilarining ta'kidlashicha, shamolning past bo'lgan davrlarini shunchaki tayyor holatda bo'lgan elektr stantsiyalarini qayta ishga tushirish yoki HVDC bilan o'zaro bog'lash orqali hal qilish mumkin.^[120] Sekin javob beradigan issiqlik elektr stantsiyalari bo'lgan va gidroelektr energiyasi ishlab chiqaradigan tarmoqlarga ulanmagan elektr tarmoqlari shamol energiyasidan foydalanishni cheklashi mumkin.^[119] 2007 yilda chop etilgan Stenford Universitetining tadqiqotlariga ko'ra Amaliy meteorologiya va iqlimshunoslik jurnali, o'n va undan ortiq shamol elektr stantsiyalarini bir-biriga bog'lab, ishlab chiqarilgan umumiy energiyaning o'rtacha 33 foizini (ya'ni, umumiy yorliq hajmining taxminan 8 foizini) ishonchli ishlatishga imkon berishi mumkin, elektr quvvati shamol tezligi va turbinaning balandligi uchun minimal mezonlarga rioya qilingan taqdirda, eng yuqori yuklarni boshqarish uchun unga ishonish mumkin.^[121][122]

Aksincha, ayniqsa shamolli kunlarda, hatto kirish darajasi 16% bo'lsa ham, shamol energiyasini ishlab chiqarish mamlakatdagi barcha boshqa elektr energiya manbalaridan oshib ketishi mumkin. Ispaniyada 2012 yil 16 aprelning dastlabki soatlarida shamol energiyasi ishlab chiqarish shu paytgacha elektr energiyasi ishlab chiqarishning eng yuqori foiziga etib, umumiy talabning 60,5 foizini tashkil etdi.^[123] 2013 yilda elektr energiyasi bozoriga 30 foizga kirgan Daniyada 90 soat ichida shamol energiyasi mamlakatning 100 foiz quvvatini ishlab chiqardi va 28 oktyabr kuni soat 2 da mamlakatning talabining 122 foizini tashkil etdi.^[124]

2006 yil Xalqaro energetika agentligi Forum o'ngdagi jadvalda ko'rsatilgandek, bir necha mamlakatlar uchun shamol energiyasining umumiy quvvatdagi ulushi funktsiyasi sifatida uzilishlarni boshqarish xarajatlarini taqdim etdi. 2009 yilda Buyuk Britaniyada shamolning o'zgaruvchanligi to'g'risidagi uchta hisobot, odatda shamolning o'zgaruvchanligini ish zaxirasiga 20% qo'shib hisobga olish kerak degan fikrga kelishadi, ammo bu tarmoqni boshqarib bo'lmaydigan holga keltirmaydi. Oddiy qo'shimcha xarajatlar miqdorini aniqlash mumkin.^[13]

O'zgaruvchan qayta tiklanadigan energiya manbalarini turiga va joylashuviga qarab diversifikatsiya qilish, ularning o'zgarishini prognoz qilish va ularni dispetcherlik bilan qayta tiklanadigan energiya manbalari, egiluvchan yonilg'i generatorlari va talabga javob berish bilan birlashtirish elektr ta'minoti ehtiyojlarini ishonchli ravishda qondirish imkoniyatiga ega bo'lgan energiya tizimini yaratishi mumkin. Qayta tiklanadigan energiyaning tobora yuqori darajalarini birlashtirish real dunyoda muvaffaqiyatli namoyish etilmoqda:

2009 yilda sakkizta amerikalik va uchta evropalik hokimiyat, etakchi elektrotexnika muhandislarining professional jurnalida yozgan holda, "elektr tarmoqlari sig'dira oladigan shamol energiyasi miqdorining ishonchli va qat'iy texnik chegarasini" topa olmadi. Aslida, 200 dan ortiq xalqaro tadqiqotlar, na AQShning sharqiy va g'arbiy mintaqalari uchun rasmiy tadqiqotlar, na Xalqaro energetika agentligi, 30% gacha o'zgaruvchan qayta tiklanadigan ta'minotni tarmoqqa ishonchli kiritish uchun katta xarajatlarni yoki texnik to'siqlarni topdi va ba'zi tadkikotlar juda ko'p.

Idealizatsiya qilingan taxminlar bo'yicha Evropada shamol va fotoelektr energiyasining sig'imi omillarining mavsumiy tsikli. Ushbu rasm shamol va quyosh energiyasining mavsumiy miqyosdagi muvozanatlashuv ta'sirini aks ettiradi (Kaspar va boshq., 2019).^[126]

Quyosh energiyasi shamolni bir-birini to'ldirishga moyil.^[127][128] Kundalikdan haftalik hisoblagichlarda, yuqori bosimli joylar osmon va past shamollarni olib kelishga moyildir, aksincha past bosimli joylar shamolli va bulutli bo'lishga moyil. Mavsumiy vaqt jadvallarida quyosh energiyasi yozda eng yuqori darajaga ko'tariladi, aksariyat joylarda shamol energiyasi yozda kam, qishda esa yuqori bo'ladi.^[D][129] Shunday qilib, shamol va quyosh energiyasining mavsumiy o'zgarishi bir-birlarini biroz bekor qilishga moyildir.^[126] 2007 yilda Quyosh energiyasini etkazib berish texnologiyasi instituti Kassel universiteti uchuvchi tomonidan sinovdan o'tgan a estrodiol elektr stantsiyasi quyosh, shamol, biogaz va gidrostoraj kecha-kunduz va butun yil davomida qayta tiklanadigan quvvat manbalaridan quvvatni ta'minlash.^[130]

Bashorat qilish

Shamol kuchini prognozlash usullari qo'llaniladi, ammo qisqa muddatli foydalanish uchun har qanday aniq shamol elektr stantsiyasining prognozi past bo'ladi. Har qanday ma'lum generator uchun shamol chiqishi bir soat ichida 10% dan kam o'zgarishi uchun 80% va 5 soat ichida 10% yoki undan ko'proq o'zgarishi uchun 40% ehtimollik mavjud.^[131]

Biroq, Grem Sinden (2009) tomonidan olib borilgan tadqiqotlar shuni ko'rsatadiki, amalda bir necha xil joylarda va shamol rejimlarida tarqalgan minglab shamol turbinalarining o'zgarishi yumshatilgan. Saytlar orasidagi masofa oshgani sayin, ushbu joylarda o'lchangan shamol tezligi o'rtasidagi o'zaro bog'liqlik kamayadi.^[E]

Thus, while the output from a single turbine can vary greatly and rapidly as local wind speeds vary, as more turbines are connected over larger and larger areas the average power output becomes less variable and more predictable.^[60][132]

Wind power hardly ever suffers major technical failures, since failures of individual wind turbines have hardly any effect on overall power, so that the distributed wind power is reliable and predictable,^{[133][ishonchli manba? ]} whereas conventional generators, while far less variable, can suffer major unpredictable outages.

Energiyani saqlash

The Sir Adam Beck Generating Complex da Niagara Falls, Canada, includes a large pumped-storage hydroelectricity reservoir. During hours of low electrical demand excess electrical grid power is used to pump water up into the reservoir, which then provides an extra 174 MW of electric power during periods of peak demand.

Typically, conventional gidroelektr complements wind power very well. When the wind is blowing strongly, nearby hydroelectric stations can temporarily hold back their water. When the wind drops they can, provided they have the generation capacity, rapidly increase production to compensate. This gives a very even overall power supply and virtually no loss of energy and uses no more water.

Alternatively, where a suitable head of water is not available, pumped-storage hydroelectricity yoki boshqa shakllari grid energy storage kabi compressed air energy storage va thermal energy storage can store energy developed by high-wind periods and release it when needed. The type of storage needed depends on the wind penetration level – low penetration requires daily storage, and high penetration requires both short- and long-term storage – as long as a month or more. Stored energy increases the economic value of wind energy since it can be shifted to displace higher-cost generation during peak demand periods. The potential revenue from this hakamlik sudi can offset the cost and losses of storage. For example, in the UK, the 2 GW Dinorwig pumped-storage plant evens out electrical demand peaks, and allows base-load suppliers to run their plants more efficiently. Although pumped-storage power systems are only about 75% efficient, and have high installation costs, their low running costs and ability to reduce the required electrical base-load can save both fuel and total electrical generation costs.^[134][135]

In particular geographic regions, peak wind speeds may not coincide with peak demand for electrical power, whether offshore or onshore. In the U.S. states of Kaliforniya va Texas, for example, hot days in summer may have low wind speed and high electrical demand due to the use of havo sovutish. Some utilities subsidize the purchase of geotermik issiqlik nasoslari by their customers, to reduce electric power demand during the summer months by making air conditioning up to 70% more efficient;^[136] widespread adoption of this technology would better match electric power demand to wind availability in areas with hot summers and low summer winds. A possible future option may be to interconnect widely dispersed geographic areas with an HVDC "super grid ". In the U.S. it is estimated that to upgrade the transmission system to take in planned or potential renewables would cost at least US$60 bn,^[137] while the social value of added wind power would be more than that cost.^[138]

Germany has an installed capacity of wind and solar that can exceed daily demand, and has been exporting peak power to neighboring countries, with exports which amounted to some 14.7 billion kWh in 2012.^[139] A more practical solution is the installation of thirty days storage capacity able to supply 80% of demand, which will become necessary when most of Europe's energy is obtained from wind power and solar power. Just as the EU requires member countries to maintain 90 days strategic reserves of oil it can be expected that countries will provide electric power storage, instead of expecting to use their neighbors for net metering.^[140]

Capacity credit, fuel savings and energy payback

The capacity credit of wind is estimated by determining the capacity of conventional plants displaced by wind power, whilst maintaining the same degree of system security.^[141][142] Ga ko'ra American Wind Energy Association, production of wind power in the United States in 2015 avoided consumption of 280 million cubic metres (73 billion US gallons) of water and reduced CO
2 emissions by 132 million metric tons, while providing US$7.3 bn in public health savings.^[143][144]

The energy needed to build a wind farm divided into the total output over its life, Energy Return on Energy Invested, of wind power varies but averages about 20–25.^[145][146] Thus, the energy payback time is typically around a year.

Ga binoan BusinessGreen, wind turbines reached panjara tengligi (the point at which the cost of wind power matches traditional sources) in some areas of Europe in the mid-2000s, and in the US around the same time. Falling prices continue to drive the Levelized cost down and it has been suggested that it has reached general grid parity in Europe in 2010, and will reach the same point in the US around 2016 due to an expected reduction in capital costs of about 12%.^[148] Ga binoan PolitiFact, it is difficult to predict whether wind power would remain viable in the United States without subsidies.^[149]

Electric power cost and trends

Estimated cost per MWh for wind power in Denmark

The Qayta tiklanadigan energiya milliy laboratoriyasi projects that the Levelized cost of wind power in the United States will decline about 25% from 2012 to 2030.^[150]

A turbine blade convoy passing through Edenfield in the U.K. (2008). Even longer 2-piece blades are now manufactured, and then assembled on-site to reduce difficulties in transportation.

Wind power is capital intensive but has no fuel costs.^[151] The price of wind power is therefore much more stable than the volatile prices of fossil fuel sources.^[152] The marjinal xarajat of wind energy once a station is constructed is usually less than 1-cent per kW·h.^[153]

However, the estimated o'rtacha narx per unit of electric power must incorporate the cost of construction of the turbine and transmission facilities, borrowed funds, return to investors (including the cost of risk), estimated annual production, and other components, averaged over the projected useful life of the equipment, which may be more than 20 years. Energy cost estimates are highly dependent on these assumptions so published cost figures can differ substantially. In 2004, wind energy cost 1/5 of what it did in the 1980s, and some expected that downward trend to continue as larger multi-megawatt turbinalar were mass-produced.^[154] In 2012 capital costs for wind turbines were substantially lower than 2008–2010 but still above 2002 levels.^[155]A 2011 report from the American Wind Energy Association stated, "Wind's costs have dropped over the past two years, in the range of 5 to 6 cents per kilowatt-hour recently.... about 2 cents cheaper than coal-fired electric power, and more projects were financed through debt arrangements than tax equity structures last year.... winning more mainstream acceptance from Wall Street's banks... Equipment makers can also deliver products in the same year that they are ordered instead of waiting up to three years as was the case in previous cycles.... 5,600 MW of new installed capacity is under construction in the United States, more than double the number at this point in 2010. Thirty-five percent of all new power generation built in the United States since 2005 has come from wind, more than new gas and coal plants combined, as power providers are increasingly enticed to wind as a convenient hedge against unpredictable commodity price moves."^[156]

A British Wind Energy Association report gives an average generation cost of onshore wind power of around 3 pence (between US 5 and 6 cents) per kW·h (2005).^[157] Cost per unit of energy produced was estimated in 2006 to be 5 to 6 percent above the cost of new generating capacity in the US for coal and natural gas: wind cost was estimated at $56 per MW·h, coal at $53/MW·h and natural gas at $53.^[158] Similar comparative results with natural gas were obtained in a governmental study in the UK in 2011.^[159] In 2011 power from wind turbines could be already cheaper than fossil or nuclear plants; it is also expected that wind power will be the cheapest form of energy generation in the future.^[11] The presence of wind energy, even when subsidized, can reduce costs for consumers (€5 billion/yr in Germany) by reducing the marginal price, by minimizing the use of expensive eng yuqori elektr stantsiyalari.^{[iqtibos kerak ]}

A 2012 EU study shows the base cost of onshore wind power similar to coal when subsidies and tashqi ta'sirlar are disregarded. Wind power has some of the lowest external costs.^[160]

In February 2013 Bloomberg New Energy Finance (BNEF) reported that the cost of generating electric power from new wind farms is cheaper than new coal or new baseload gas plants. When including the current Australian federal government carbon pricing scheme their modeling gives costs (in Australian dollars) of $80/MWh for new wind farms, $143/MWh for new coal plants, and $116/MWh for new baseload gas plants. The modeling also shows that "even without a carbon price (the most efficient way to reduce economy-wide emissions) wind energy is 14% cheaper than new coal and 18% cheaper than new gas."^[161]Part of the higher costs for new coal plants is due to high financial lending costs because of "the reputational damage of emissions-intensive investments". The expense of gas-fired plants is partly due to the "export market" effects on local prices. Costs of production from coal-fired plants built-in "the 1970s and 1980s" are cheaper than renewable energy sources because of depreciation.^[161] In 2015 BNEF calculated the levelized cost of electricity (LCOE) per MWh in new powerplants (excluding carbon costs):$85 for onshore wind ($175 for offshore), $66–75 for coal in the Americas ($82–105 in Europe), gas $80–100.^{[162][163][164]} A 2014 study showed unsubsidized LCOE costs between $37–81, depending on the region.^[165] A 2014 US DOE report showed that in some cases power purchase agreement prices for wind power had dropped to record lows of $23.5/MWh.^[166]

The cost has reduced as wind turbine technology has improved. There are now longer and lighter wind turbine blades, improvements in turbine performance, and increased power generation efficiency. Also, wind project capital expenditure costs and maintenance costs have continued to decline.^[167]For example, the wind industry in the US in early 2014 was able to produce more power at lower cost by using taller wind turbines with longer blades, capturing the faster winds at higher elevations. This has opened up new opportunities and in Indiana, Michigan, and Ohio, the price of power from wind turbines built 90–120 metres (300–400 ft) above the ground can since 2014 compete with conventional fossil fuels like coal. Prices have fallen to about 4 cents per kilowatt-hour in some cases and utilities have been increasing the amount of wind energy in their portfolio, saying it is their cheapest option.^[168]

Some initiatives are working to reduce the costs of electric power from offshore wind. Bir misol Carbon Trust Offshore Wind Accelerator, a joint industry project, involving nine offshore wind developers, which aims to reduce the cost of offshore wind by 10% by 2015. It has been suggested that innovation at scale could deliver a 25% cost reduction in offshore wind by 2020.^[169] Henrik Stiesdal, former Chief Technical Officer at Siemens Wind Power, has stated that by 2025 energy from offshore wind will be one of the cheapest, scalable solutions in the UK, compared to other renewables and fossil fuel energy sources if the true cost to society is factored into the cost of the energy equation.^[170] He calculates the cost at that time to be 43 EUR/MWh for onshore, and 72 EUR/MWh for offshore wind.^[171]

In August 2017, the Department of Energy's National Renewable Energy Laboratory (NREL) published a new report on a 50% reduction in wind power cost by 2030. The NREL is expected to achieve advances in wind turbine design, materials, and controls to unlock performance improvements and reduce costs. According to international surveyors, this study shows that cost-cutting is projected to fluctuate between 24% and 30% by 2030. In more aggressive cases, experts estimate cost reduction of up to 40% if the research and development and technology programs result in additional efficiency.^[172]

In 2018 a Lazard study found that "The low end Levelized cost of onshore wind-generated energy is $29/MWh, compared to an average illustrative marginal cost of $36/MWh for coal", and noted that the average cost had fallen by 7% in a year.^[2]

Incentives and community benefits

U.S. landowners typically receive $3,000–$5,000 annual rental income per wind turbine, while farmers continue to grow crops or graze cattle up to the foot of the turbines.^[173] Shown: the Brazos Wind Farm, Texas.

Some of the 6,000 turbines in California's Altamont Pass Wind Farm aided by tax incentives during the 1980s.^[174]

The wind industry in the United States generates tens of thousands of jobs and billions of dollars of economic activity.^[175] Wind projects provide local taxes, or payments in place of taxes and strengthen the economy of rural communities by providing income to farmers with wind turbines on their land.^[173][176]Wind energy in many jurisdictions receives financial or other support to encourage its development. Wind energy benefits from subsidiyalar in many jurisdictions, either to increase its attractiveness or to compensate for subsidies received by other forms of production which have significant negative externalities.

In the US, wind power receives a production tax credit (PTC) of 2¢/kWh in 1993 dollars for each kW·h produced, for the first 10 years; at 2¢ per kW·h in 2012, the credit was renewed on 2 January 2012, to include construction begun in 2013.^[177]A 30% tax credit can be applied instead of receiving the PTC.^[178][179]Another tax benefit is accelerated depreciation. Many American states also provide incentives, such as exemption from property tax, mandated purchases, and additional markets for "green credits ".^[180] The Energy Improvement and Extension Act of 2008 contains extensions of credits for wind, including microturbines. Countries such as Kanada and Germany also provide incentives for wind turbine construction, such as tax credits or minimum purchase prices for wind generation, with assured grid access (sometimes referred to as ovqatlanish tariflari ). These feed-in tariffs are typically set well above average electric power prices.^[181][182]In December 2013 U.S. Senator Lamar Aleksandr and other Republican senators argued that the "wind energy production tax credit should be allowed to expire at the end of 2013"^[183] and it expired 1 January 2014 for new installations.

Secondary market forces also provide incentives for businesses to use wind-generated power, even if there is a premium price for the electricity. Masalan, socially responsible manufacturers pay utility companies a premium that goes to subsidize and build new wind power infrastructure. Companies use wind-generated power, and in return, they can claim that they are undertaking strong "green" efforts. In the US the organization Green-e monitors business compliance with these renewable energy credits.^[184]Turbine prices have fallen significantly in recent years due to tougher competitive conditions such as the increased use of energy auctions, and the elimination of subsidies in many markets. Masalan, Vestalar, a wind turbine manufacturer, whose largest onshore turbine can pump out 4.2 megawatts of power, enough to provide electricity to roughly 5,000 homes, has seen prices for its turbines fall from €950,000 per megawatt in late 2016, to around €800,000 per megawatt in the third quarter of 2017.^[185]

Small-scale wind power

Kichkina Quietrevolution QR5 Gorlov type vertical axis wind turbine on the roof of Kolston Xoll yilda Bristol, Angliya. Measuring 3 m in diameter and 5 m high, it has a nameplate rating of 6.5 kW.

Small-scale wind power is the name given to wind generation systems with the capacity to produce up to 50 kW of electrical power.^[186] Isolated communities, that may otherwise rely on dizel generators, may use wind turbines as an alternative. Individuals may purchase these systems to reduce or eliminate their dependence on grid electric power for economic reasons, or to reduce their uglerod izi. Wind turbines have been used for household electric power generation in conjunction with batareya storage over many decades in remote areas.^[187]

Recent examples of small-scale wind power projects in an urban setting can be found in Nyu-York shahri, where, since 2009, several building projects have capped their roofs with Gorlov-type helical wind turbines. Although the energy they generate is small compared to the buildings' overall consumption, they help to reinforce the building's 'green' credentials in ways that "showing people your high-tech boiler" cannot, with some of the projects also receiving the direct support of the New York State Energy Research and Development Authority.^[188]

Grid-connected domestic wind turbines may use grid energy storage, thus replacing purchased electric power with locally produced power when available. The surplus power produced by domestic microgenerators can, in some jurisdictions, be fed into the network and sold to the utility company, producing a retail credit for the microgenerators' owners to offset their energy costs.^[189]

Off-grid system users can either adapt to intermittent power or use batteries, fotoelektrik, or diesel systems to supplement the wind turbine.^[190] Equipment such as parking meters, traffic warning signs, street lighting, or wireless Internet gateways may be powered by a small wind turbine, possibly combined with a photovoltaic system, that charges a small battery replacing the need for a connection to the power grid.^[191]

A Carbon Trust study into the potential of small-scale wind energy in the UK, published in 2010, found that small wind turbines could provide up to 1.5 terawatt-hours (TW·h) per year of electric power (0.4% of total UK electric power consumption), saving 600,000 tons of carbon dioxide (Mt CO₂) emission savings. This is based on the assumption that 10% of households would install turbines at costs competitive with grid electric power, around 12 pence (US 19 cents) a kW·h.^[192] A report prepared for the UK's government-sponsored Energiyani tejashga ishonch in 2006, found that home power generators of various kinds could provide 30 to 40% of the country's electric power needs by 2050.^[193]

The environmental impact of wind power is considered to be relatively minor compared to that of fossil fuels. Ga ko'ra IPCC, in assessments of the life-cycle greenhouse-gas emissions of energy sources, wind turbines have a o'rtacha value of 12 and 11 (gCO
2tenglama /kVt soat ) for offshore and onshore turbines, respectively.^[196][197] Compared with other low carbon power sources, wind turbines have some of the lowest global isish salohiyati per unit of electrical energy generated.^[198]

Onshore wind farms can have a significant visual impact and impact on the landscape.^[199] Their network of turbines, access roads, transmission lines, and substations can result in "energy sprawl".^[7] Wind farms typically need to cover more land and be more spread out than other power stations.^[6] However, the land between the turbines and roads can still be used for agriculture.^[200][201]

Wind farms are typically built in wild and rural areas, which can lead to "industrialization of the countryside".^{[8][shubhali – muhokama qilish]} va yashash joylarini yo'qotish.^[7] Habitat loss and habitat fragmentation are the greatest impacts of wind farms on wildlife.^[7] There are also reports of higher bird and bat mortality at wind turbines as there are around other artificial structures. The scale of the ecological impact may^[202] or may not^[203] be significant, depending on specific circumstances. Prevention and mitigation of wildlife fatalities, and protection of torf boglari,^[204] affect the siting and operation of wind turbines.

Wind turbines generate noise. At a residential distance of 300 metres (980 ft) this may be around 45 dB, which is slightly louder than a refrigerator. At 1.5 km (1 mi) distance they become inaudible.^[205][206]There are anecdotal reports of negative health effects from noise on people who live very close to wind turbines.^[207]Peer-reviewed research has generally not supported these claims.^{[208][209][210]}

The United States Air Force and Navy have expressed concern that siting large wind turbines near bases "will negatively impact radar to the point that air traffic controllers will lose the location of aircraft."^[211]

Before 2019, many wind turbine blades had been made of shisha tola with designs that only provided a service lifetime of 10 to 20 years.^[212] Given the available technology, as of February 2018, there was no market for recycling these old blades,^[213] and they are commonly disposed of in landfills. Because blades are designed to be hollow, they take up a large volume compared to their mass. Landfill operators have therefore started requiring operators to crush the blades before they can be landfilled.^[212]

Atom energiyasi va Yoqilg'i moyi bor subsidized by many governments, and wind power and other forms of renewable energy are also often subsidized. For example, a 2009 study by the Environmental Law Institute^[214] assessed the size and structure of U.S. energy subsidies over the 2002–2008 period. The study estimated that subsidies to fossil-fuel-based sources amounted to approximately $72 billion over this period and subsidies to renewable fuel sources totaled $29 billion. In the United States, the federal government has paid US$74 billion for energy subsidies to support Ilmiy-tadqiqot ishlari uchun atom energiyasi ($50 billion) and Yoqilg'i moyi ($24 billion) from 1973 to 2003. During this same time frame, qayta tiklanadigan energiya technologies and energiya samaradorligi received a total of US$26 billion. It has been suggested that a subsidy shift would help to level the playing field and support growing energy sectors, namely quyosh energiyasi, wind power, and bioyoqilg'i.^[215] History shows that no energy sector was developed without subsidies.^[215]

Ga ko'ra Xalqaro energetika agentligi (IEA) (2011), energy subsidies artificially lower the price of energy paid by consumers, raise the price received by producers or lower the cost of production. "Fossil fuels subsidies costs generally outweigh the benefits. Subsidies to renewables and low-carbon energy technologies can bring long-term economic and environmental benefits".^[216]In November 2011, an IEA report entitled Deploying Renewables 2011 said: "subsidies in green energy technologies that were not yet competitive are justified to give an incentive to investing into technologies with clear environmental and energy security benefits". The IEA's report disagreed with claims that renewable energy technologies are only viable through costly subsidies and not able to produce energy reliably to meet demand.

However, IEA's views are not universally accepted. Between 2010 and 2016, subsidies for wind were between 1¢ and 6¢ per kWh. Subsidies for coal, natural gas, and nuclear are all between 0.05¢ and 0.2¢ per kWh overall years. On a per-kWh basis, wind is subsidized 50 times as much as traditional sources.^[217]

In the United States, the wind power industry has recently increased its lobbying efforts considerably, spending about $5 million in 2009 after years of relative obscurity in Washington.^[218] By comparison, the U.S. nuclear industry alone spent over $650 million on its lobbying efforts and campaign contributions during 10 years ending in 2008.^{[219][220][221]}

Keyingi 2011 yil Yaponiyaning yadroviy baxtsiz hodisalari, Germany's federal government is working on a new plan for increasing energiya samaradorligi va renewable energy commercialization, with a particular focus on offshore wind farms. Under the plan, large wind turbines will be erected far away from the coastlines, where the wind blows more consistently than it does on land, and where the enormous turbines won't bother the inhabitants. The plan aims to decrease Germany's dependence on energy derived from coal and nuclear power plants.^[222]

Jamoatchilik fikri

Environmental group members are both more in favor of wind power (74%) as well as more opposed (24%). Few are undecided.

Surveys of public attitudes across Evropa and in many other countries show strong public support for wind power.^{[223][224][225]}About 80% of EU citizens support wind power.^[226]Yilda Germaniya, where wind power has gained very high social acceptance, hundreds of thousands of people have invested in citizens' wind farms across the country and thousands of small and medium-sized enterprises are running successful businesses in a new sector that in 2008 employed 90,000 people and generated 8% of Germany's electric power.^[227][228]

Bakker va boshq. (2012) discovered in their study that when residents did not want the turbines located by them their annoyance was significantly higher than those "that benefited economically from wind turbines the proportion of people who were rather or very annoyed was significantly lower".^[229]

Although wind power is a popular form of energy generation, the construction of wind farms is not universally welcomed, often for estetik sabablari.^{[200][223][224][225][226][230][231]}

Yilda Ispaniya, with some exceptions, there has been little opposition to the installation of inland wind parks. However, the projects to build offshore parks have been more controversial.^[232]In particular, the proposal of building the biggest offshore wind power production facility in the world in southwestern Spain on the coast of Kadis, on the spot of the 1805 Trafalgar jangi^[233] has been met with strong opposition who fear for tourism and fisheries in the area,^[234] and because the area is a war grave.^[233]

Which should be increased in Scotland?^[235]

Tomonidan o'tkazilgan so'rovnomada Angus Reid Strategies in October 2007, 89 percent of respondents said that using renewable energy sources like wind or solar power was positive for Kanada because these sources were better for the environment. Only 4 percent considered using renewable sources as negative since they can be unreliable and expensive.^[236]According to a Saint Consulting survey in April 2007, wind power was the muqobil energiya source most likely to gain public support for future development in Canada, with only 16% opposed to this type of energy. By contrast, 3 out of 4 Canadians opposed nuclear power developments.^[237]

A 2003 survey of residents living around Shotlandiya 's 10 existing wind farms found high levels of community acceptance and strong support for wind power, with much support from those who lived closest to the wind farms. The results of this survey support those of an earlier Scottish Executive survey 'Public attitudes to the Environment in Scotland 2002', which found that the Scottish public would prefer the majority of their electric power to come from renewables, and which rated wind power as the cleanest source of renewable energy.^[238]A survey conducted in 2005 showed that 74% of people in Scotland agree that wind farms are necessary to meet current and future energy needs. When people were asked the same question in a Scottish renewables study conducted in 2010, 78% agreed. The increase is significant as there were twice as many wind farms in 2010 as there were in 2005. The 2010 survey also showed that 52% disagreed with the statement that wind farms are "ugly and a blot on the landscape". 59% agreed that wind farms were necessary and that how they looked was unimportant.^[239]Haqida turizm, query responders consider power pylons, cell phone towers, karerlar va plantatsiyalar more negatively than wind farms.^[240] Scotland is planning to obtain 100% of electric power from renewable sources by 2020.^[241]

In other cases, there is direct community ownership of wind farm projects. The hundreds of thousands of people who have become involved in Germany's small and medium-sized wind farms demonstrate such support there.^[242]

A 2010 Harris Poll reflects the strong support for wind power in Germany, other European countries, and the United States.^{[223][224][243]}

Yilda Xitoy, Shen et al. (2019) discover that Chinese city-dwellers may be somewhat resistant to building wind turbines in urban areas, with a surprisingly high proportion of people citing an unfounded fear of radiation as driving their concerns.^[245] The central Chinese government rather than scientists is better suited to address this concern. Also, the study finds that like their counterparts in OECD countries, urban Chinese respondents are sensitive to direct costs and wildlife externalities. Distributing relevant information about turbines to the public may alleviate resistance.

Hamjamiyat

Wind turbines such as these, in Kumbriya, England, have been opposed for a number of reasons, including aesthetics, by some sectors of the population.^[246][247]

Many wind power companies work with local communities to reduce environmental and other concerns associated with particular wind farms.^{[248][249][250]}In other cases there is direct community ownership of wind farm projects. Appropriate government consultation, planning and approval procedures also help to minimize environmental risks.^{[223][251][252]}Some may still object to wind farms^[253] but, according to Avstraliya instituti, their concerns should be weighed against the need to address the threats posed by Iqlim o'zgarishi and the opinions of the broader community.^[254]

In America, wind projects are reported to boost local tax bases, helping to pay for schools, roads, and hospitals. Wind projects also revitalize the economy of rural communities by providing steady income to farmers and other landowners.^[173]

In the UK, both the Milliy ishonch va Angliyaning qishloqlarini himoya qilish kampaniyasi have expressed concerns about the effects on the rural landscape caused by inappropriately sited wind turbines and wind farms.^[255][256]

In Denmark, a loss-of-value scheme gives people the right to claim compensation for loss of value of their property if it is caused by proximity to a wind turbine. The loss must be at least 1% of the property's value.^[258]

Despite this general support for the concept of wind power in the public at large, local opposition often exists and has delayed or aborted a number of projects.^{[259][260][261]}For example, there are concerns that some installations can negatively affect TV and radio reception and Doppler weather radar, as well as produce excessive sound and vibration levels leading to a decrease in property values.^[262] Potential broadcast-reception solutions include predictive interference modeling as a component of site selection.^[263][264]A study of 50,000 home sales near wind turbines found no statistical evidence that prices were affected.^[265]

While aesthetic issues are subjective and some find wind farms pleasant and optimistic, or symbols of energetik mustaqillik and local prosperity, protest groups are often formed to attempt to block new wind power sites for various reasons.^{[253][266][267]}

This type of opposition is often described as NIMBYism,^[268] but research carried out in 2009 found that there is little evidence to support the belief that residents only object to renewable power facilities such as wind turbines as a result of a "Not in my Back Yard" attitude.^[269]

Geosiyosat

It has been argued that expanding the use of wind power will lead to increasing geopolitical competition over critical materials for wind turbines such as rare earth elements neodymium, praseodymium, and dysprosium. But this perspective has been criticised for failing to recognise that most wind turbines do not use permanent magnets and for underestimating the power of economic incentives for expanded production of these minerals.^[270]

Shamol turbinalari are devices that convert the wind's kinetik energiya into electrical power. The result of over a millennium of shamol tegirmoni development and modern engineering, today's wind turbines are manufactured in a wide range of horizontal axis and vertikal o'q turlari. The smallest turbines are used for applications such as battery charging for auxiliary power. Slightly larger turbines can be used for making small contributions to a domestic power supply while selling unused power back to the utility supplier via the electrical grid. Arrays of large turbines, known as shamol stansiyalari, have become an increasingly important source of qayta tiklanadigan energiya and are used in many countries as part of a strategy to reduce their reliance on Yoqilg'i moyi.

Wind turbine design is the process of defining the form and specifications of a shamol turbinasi to extract energy from the shamol.^[271]A wind turbine installation consists of the necessary systems needed to capture the wind's energy, point the turbine into the wind, convert mechanical rotation ichiga elektr quvvati, and other systems to start, stop, and control the turbine.

In 1919 the German physicist Albert Betz showed that for a hypothetical ideal wind-energy extraction machine, the fundamental laws of conservation of mass and energy allowed no more than 16/27 (59%) of the kinetic energy of the wind to be captured. Bu Betz limit can be approached in modern turbine designs, which may reach 70 to 80% of the theoretical Betz limit.^[272][273]

The aerodynamics of a wind turbine are not straightforward. The airflow at the blades is not the same as the airflow far away from the turbine. The very nature of how energy is extracted from the air also causes air to be deflected by the turbine. This affects the objects or other turbines downstream, which is known as Wake effect. Shuningdek, aerodinamika of a wind turbine at the rotor surface exhibit phenomena that are rarely seen in other aerodynamic fields. The shape and dimensions of the blades of the wind turbine are determined by the aerodynamic performance required to efficiently extract energy from the wind, and by the strength required to resist the forces on the blade.^[274]

In addition to the aerodynamic design of the blades, the design of a complete wind power system must also address the design of the installation's rotor hub, nacelle, tower structure, generator, controls, and foundation.^[275]
