Photovoltaic kuphatikiza kusungirako mphamvu, mwachidule, ndi kuphatikiza kwa mphamvu ya dzuwa ndi kusungirako batire. Pamene mphamvu yolumikizidwa ndi gridi ya photovoltaic imakhala yokwera kwambiri, zotsatira za gridi yamagetsi zikuwonjezeka, ndipo kusungirako mphamvu kumayang'anizana ndi mwayi wokulirapo.
Photovoltais kuphatikiza kusungirako mphamvu kumakhala ndi maubwino ambiri. Choyamba, zimatsimikizira mphamvu yokhazikika komanso yodalirika. Chipangizo chosungira mphamvu chili ngati batire lalikulu lomwe limasunga mphamvu zochulukirapo za dzuwa. Dzuwa likakhala losakwanira kapena kufunikira kwa magetsi kuli kwakukulu, limatha kupereka mphamvu kuti zitsimikizire kuti magetsi amapitilirabe.
Kachiwiri, ma photovoltais kuphatikiza kusungirako mphamvu kungapangitsenso kupanga magetsi adzuwa kukhala ndalama zambiri. Mwa kukhathamiritsa ntchito, imatha kulola kuti magetsi ambiri agwiritsidwe ntchito pawokha ndikuchepetsa mtengo wogulira magetsi. Kuphatikiza apo, zida zosungiramo magetsi zitha kutenga nawo gawo pamsika wothandizira mphamvu kuti zibweretse zopindulitsa zina. Kugwiritsa ntchito ukadaulo wosungira mphamvu kumapangitsa kuti magetsi adzuwa azikhala osinthika komanso amatha kukwaniritsa zosowa zosiyanasiyana zamagetsi. Panthawi imodzimodziyo, imathanso kugwira ntchito ndi mafakitale opangira mphamvu kuti akwaniritse zofunikira za mphamvu zambiri komanso kugwirizanitsa kwazinthu ndi zofunikira.
Kusungirako mphamvu ya Photovoltaic ndikosiyana ndi magetsi opangidwa ndi gridi yoyera. Mabatire osungira mphamvu ndi kuyitanitsa ndi kutulutsa zida ziyenera kuwonjezeredwa. Ngakhale mtengo wakutsogolo udzakwera pang'onopang'ono, kuchuluka kwa ntchito kumakhala kokulirapo. Pansipa tikuwonetsa zochitika zinayi zotsatirazi za photovoltaic + zosungira mphamvu zogwiritsira ntchito potengera ntchito zosiyanasiyana: mawonekedwe ogwiritsira ntchito magetsi a photovoltaic off-grid, photovoltaic off-grid energy storage scenarios, photovoltaic grid-connected energy storage scenarios and microgrid energy storage applications. Zochitika.

Njira zogwiritsira ntchito Microgrid Energy Storage System
Monga chida chofunikira chosungiramo mphamvu, makina osungira mphamvu a microgrid amatenga gawo lofunikira kwambiri pakukulitsa mphamvu zatsopano za dziko langa komanso dongosolo lamagetsi. Ndi kupita patsogolo kwa sayansi ndi ukadaulo komanso kutchuka kwa mphamvu zongowonjezwdwa, mawonekedwe ogwiritsira ntchito makina osungira mphamvu a microgrid akupitiliza kukula, makamaka kuphatikiza zinthu ziwiri izi:
1. Kugawidwa kwamagetsi ndi njira yosungiramo mphamvu: Kugawidwa kwa magetsi kumatanthawuza kukhazikitsidwa kwa zida zazing'ono zopangira magetsi pafupi ndi gawo la ogwiritsa ntchito, monga photovoltaic ya dzuwa, mphamvu ya mphepo, ndi zina zotero, ndipo mphamvu yowonjezera mphamvu imasungidwa kupyolera mu dongosolo losungiramo mphamvu. kotero kuti itha kugwiritsidwa ntchito panthawi yamagetsi apamwamba kwambiri kapena Imapereka mphamvu panthawi yakulephera kwa gridi.
2. Kusungirako magetsi a Microgrid: M'madera akutali, zilumba ndi malo ena omwe kupeza gridi yamagetsi kumakhala kovuta, makina osungira mphamvu a microgrid angagwiritsidwe ntchito ngati magetsi osungira kuti apereke magetsi okhazikika kuderalo.
Ma Microgrid amatha kugwiritsa ntchito mokwanira komanso moyenera mphamvu zogawira mphamvu zoyera kudzera pakuwonjezera mphamvu zambiri, kuchepetsa zinthu zoyipa monga mphamvu yaying'ono, kupanga magetsi osakhazikika, komanso kudalirika kochepa kwamagetsi odziyimira pawokha, kuwonetsetsa kuti gridi yamagetsi ikugwira ntchito motetezeka, ndipo ndi njira yabwino. zowonjezera zothandiza kumagulu akuluakulu amagetsi. Zochitika zogwiritsa ntchito ma Microgrid ndizosinthika, kukula kwake kumatha kuchoka pa masauzande a watts mpaka makumi a megawatts, ndipo kuchuluka kwa ntchito ndikokulirapo.
