Nzira nhatu dzekugadzirisa dzesimba rezuva + simba rekuchengetedza

Nepo izwi rekuti "solar + chengetedzo" richiwanzotaurwa nezvaro mumatenderedzwa emagetsi, kutarisisa kushoma kwakabhadharwa kune rudzi rwesolar + yekuchengetedza inotaurwa nezvayo. Kazhinji kutaura, Inogona kugadzirisa solar + simba rekuchengetedza munzira nhatu dzinobvira:

• Standalone AC-yakabatana solar + simba rekuchengetedza: Simba rekuchengetedza simba rinowanikwa pane imwe nzvimbo yakasiyana kubva kune simba rezuva. Rudzi urwu rwekuisa runowanzo shanda nzvimbo-dzinomanikidzwa nzvimbo.

• Co-located AC-coupled solar + Storage systems: Nzvimbo yekugadzira simba rezuva uye hurongwa hwekuchengetedza simba zvakabatanidzwa uye zvinogovera nzvimbo imwe chete yekubatanidza negridi kana kuti dzine nzvimbo mbiri dzakasununguka dzekubatanidza. Nekudaro, iyo solar simba rekugadzira system uye iyo simba rekuchengetedza sisitimu yakabatana kune yakaparadzana inverter. Iyo simba rekuchengetedza system reservoir iri padivi peiyo solar power generation system. Vanogona kutumira simba pamwechete kana vakazvimiririra.

• Co-located DC-coupled solar + simba rekuchengetedza sisitimu: Nzvimbo yekugadzira simba rezuva uye simba rekuchengetedza simba zvakabatanidzwa. Uye govana iyo yakafanana yekubatanidza. Zvakare, iwo akabatana pane imwechete DC bhazi uye anoshandisa yakafanana inverter. Vanogona kushandiswa sechinhu chimwe chete.

Zvakanakira kuendesa masisitimu ekuchengetedza simba zvakazvimiririra.

Solar magetsi ekugadzira masisitimu uye masisitimu ekuchengetedza magetsi haafanire kunge ari pamwe chete kuti uwane mabhenefiti. Pasinei nekwavanowanikwa pagridi, zvivakwa zvekumira-yega zvekuchengetedza magetsi zvinogona kupa masevhisi egidhi uye kutsausa simba rakawandisa kubva kune zvinogoneka kusvika kunguva dzesimba dzemanheru. Kana solar power generic resource iri kure nenzvimbo yekuremedza, iyo yakakwana yekumisikidza yemuviri inogona kunge iri yekuendesa yakazvimirira simba rekuchengetedza sisitimu padyo nenzvimbo yekuremedza. Semuenzaniso, Fluence yakaisa 4-awa yekuchengetera bhatiri system ine yakasimwa inokwana 30MW pedyo neSan Diego kuti ive nechokwadi chekuvimbika kwenzvimbo uye kuwedzera kushandiswa kwesimba rinodzokororwa. Zvishandiso nevagadziri vanofanirwa kutarisisa kuendesa masisitimu ekuchengetedza simba anogona kana kusave ari pamwe chete nesolar magetsi masisitimu, chero ivo vaine yakanyanya kunaka mambure.

Zvakanakira solar + simba rekuchengetedza co-nzvimbo yekuendesa

Muzviitiko zvakawanda, solar + yekuchengetedza co-nzvimbo ine zvakanakira zvakanakira. Nekubatanidzwa-nzvimbo yekuendesa, solar + yekuchengetedza inogona kuenzanisa mutengo wepurojekiti, kusanganisira ivhu, vashandi, manejimendi epurojekiti, mvumo, kubatanidza, mashandiro, uye kugadzirisa. MuUS, varidzi veprojekiti vanogona zvakare kukumbira kiredhiti yemutero wekudyara kune yakawanda yekuchengetedza mari inodhura kana vaine basa rezuva.

Iyo solar + yekuchengetedza co-nzvimbo yekuendesa inogona kuve AC zvakabatanidzwa, uko iyo simba rekuchengetedza sisitimu uye solar simba rekugadzira system zvakabatanidzwa asi hazvigove inverters. Inogona zvakare kushandisa DC coupling system. Iyo solar power generic system uye simba rekuchengetedza sisitimu yakabatanidzwa padivi reDC reiyo yakagovaniswa bidirectional inverter, uye mutengo wepurojekiti unogona kugovaniswa uye kuenzana. Zvinoenderana neongororo yakaitwa neNREL, panosvika 2020, Ichadzikisa mitengo yekuenzanisa system ne30% uye 40% kune yakabatana AC-yakabatana uye DC-yakabatana solar + kuchengetedza, zvichiteerana.

Kuenzanisa kweDC-yakabatana kana AC-yakabatana deployments

Paunenge uchiongorora iyo DC-yakabatana solar + yekuchengetedza system, zvimwe zvakakosha zvinofanirwa kufunga. Mabhenefiti makuru eDC akasanganiswa solar + simba rekuchengetedza masisitimu ndeaya:

• Kuderedzwa kwemitengo yemidziyo nekudzikisa mutengo wekuisa ma inverters, medium voltage switchgear, uye zvimwe zvivakwa.

• Inobvumira solar power system kutora simba rezuva rinowanzorasika kana kuderedzwa kana inverter load factor yakakura kudarika 1, zvichiita imwe mari.

• Inogona kubatanidza solar + kuchengetedza simba muchibvumirano chekutenga simba rimwe chete (PPA).

Izvo zvakashata zveDC zvakasanganiswa solar + simba rekuchengetedza masisitimu ndeaya:

Kuenzaniswa ne AC-yakabatana solar-plus-storage systems, DC-yakabatana solar-plus-storage systems ine zvishoma kushanda kushanduka nokuti inogumira ne inverter simba apo simba rekubatanidza rakanyanya kukura. Semuyenzaniso, kana mugadziri wezuva achitarisira kudiwa kukuru mukati memaawa epamusoro pekugadzira solar, inogona kusakwanisa kuchaja mabhatiri panguva imwe chete. Kunyange ichi chiri mukana wekuderera, harisi dambudziko rakakura mumisika zhinji.

Indasitiri mukati vanotenda kuti DC yakasanganiswa solar + simba rekuchengetedza sisitimu ndiyo yakanyanya kurongeka. Inogona kupa yakagadzikana kugadzirwa kwesimba rezuva kwenguva yakareba, senge maawa 4-6, kutora iyo yakatemwa yezuva simba. Nekuda kweiyo yakagovaniswa inverter, Iyo mudziyo inoderedza mutengo wekugadzira magetsi. DC-yakabatana solar-plus-storage deployments inotarisirwa kuwedzera mumakore mashoma anotevera sezvo mamwe magridi anoshanda akatarisana nekuwedzera kuoma kwedhadha curve.
