"Uhlelo lokugcina amandla lwe-photovoltaic" lungabhekisela futhi ohlelweni lokukhiqiza amandla olusebenzisa amandla elanga lokugcina amandla. Idivayisi ye-photovoltaic kanye nedivayisi yokugcina amandla yizingxenye ezimbili eziyinhloko zesistimu yokugcina amandla ye-PV, uma sikubeka kalula.
Uma amandla ohlelo lwe-photovoltaic enganele, uhlelo lokugcina amandla luzoguqula ugesi ogciniwe ube ugesi oshintshayo odingekayo ukuze usetshenziswe kugridi yamandla. Uhlobo olulodwa lwemishini ye-photovoltaic luzoguqula amandla elanga abe ugesi, kanti olunye uhlobo lwemishini yokugcina amandla luzokhiqiza ugesi wokugcina.
Ingahlukaniswa futhi ibe izinhlelo zokugcina amandla ezixhunywe kugridi ye-photovoltaic, izinhlelo zokugcina amandla ze-microgrid, kanye nezinhlelo zokukhiqiza amandla ze-photovoltaic ezingaphandle kwegridi. Sizohlola ukuthi yiziphi izici zezinhlelo zokugcina amandla elanga ezikhethwayo ngokuningiliziwe ngezansi.
1. Izindleko ezishibhile kanye nokusebenza kahle kokukhiqizwa kwamandla aphezulu
Emini, amandla elanga angaguqulwa abe ugesi kusetshenziswa izinhlelo zokugcina amandla ze-photovoltaic. Lezi zinhlelo zigcina ugesi, bese uguqulwa ube yigridi kagesi egciniwe edingekayo ukuze kukhishwe ugesi oshintshanayo ebusuku.
Lokhu kuvumela ukuguqulwa kwamandla elanga abe ugesi, kunciphisa kakhulu izindleko zokukhiqizwa kwamandla kanye nokusetshenziswa kukagesi. Kuphinde kufeze ukuzikhiqiza nokuzisebenzisa kokukhiqiza amandla e-photovoltaic ngezinga elithile.
2. Nikeza ugesi ohlanzekile, khuthaza ukongiwa kwamandla, kanye nokunciphisa ukukhishwa kwegesi
Uhlelo lokuphehla ugesi lokugcina amandla nge-photovoltaic lungaguqula amandla elanga abe yisitoreji samandla kagesi. Uma kudingeka, la mandla agcinwa kugridi yamandla bese ekhishwa ukuze asetshenziswe njengogesi oshintshanayo. Lolu hlelo lukhiqiza ugesi kusetshenziswa amandla elanga ahlanzekile, avuselelekayo, anegalelo elikhulu ekongiweni kwamandla.
Ngaphezu kwalokho, amandla akhiqizwa yilolu hlelo lokukhiqiza amandla ahlanzekile kakhulu ngoba lunama-harmonics amancane. Lunganciphisa ukukhishwa kwegesi futhi longe amandla ngenkathi luthuthukisa nekhwalithi yohlelo lukagesi.
3. Kungakhuphula ukuphepha kwegridi kagesi
Ukuguquguquka nokuphepha kokusetshenziswa kwezinsizakusebenza zamandla kagesi kungakhuliswa kakhulu yizinhlelo zokugcina amandla ze-photovoltaic, ezinganikeza nendima efanele yokuvikela igridi uma kwenzeka ukwehluleka kwegridi noma izimo ezingalindelekile. Ngaphezu kwalokho, zingafeza ukugeleza okubili kokugcinwa kwamandla kanye nokukhiqizwa kwamandla, zinciphise inani lamandla angasetshenziswa kabusha, futhi zandise ijubane lapho kusetshenziswa amandla avuselelekayo.
Ngamafuphi, uhlelo lokugcina amandla lwe-photovoltaic lusebenzisa amandla elanga ukukhiqiza ugesi. Lolu hlelo alugcini nje ngokusiza ekuguqulweni kwamandla elanga abe amandla kagesi, kodwa futhi luvumela ukuguqulwa kwamanje aqondile kanye namanje ashintshanayo. Ngenxa yalokho, izindleko zohlelo lokukhiqiza ugesi ziyancipha kakhulu, futhi ukusetshenziswa kwamandla okuzenzela kungathuthukisa kokubili ukukhiqizwa kukagesi kanye nokusebenza kahle kokusetshenziswa.
Ngaphezu kwalokho, izinhlelo zokukhiqiza amandla okugcina amandla elanga zingathuthukisa ukuphepha kwegridi futhi zanelise isidingo sokunciphisa ukukhishwa kwegesi kanye nokonga amandla. Incazelo yokugcina amandla elanga ihlanganisiwe ngenhla.
