1. Ukubukwa Kwephrojekthi

Le phrojekthi ihilela ukuthunyelwa kohlelo oluhlanganisiwe lwe-AC oluhlanganiswe ne-AC endaweni yokuthengisa i-4S yeklayenti eCambodia. Luhlanganisa i-inverter ye-photovoltaic engu-125kW kanye nohlelo lokugcina amandla olusha olwengeziwe, olwenza kube nokusebenza okubili: 'ukuzikhiqizela ngokwakho ukuzisebenzisa ngokufaka okungaphezulu kugridi' kanye 'namandla okusekelayo angaphandle kwegridi'. Umklamo wohlelo ubheka ngokugcwele amaphethini okusetshenziswa kukagesi kweklayenti (isilinganiso sokusetshenziswa kwansuku zonke esingaba ngu-14.8kWh, amahora okusebenza angu-8:00–20:00) futhi lusekela ukuthengiswa kukagesi ongaphezulu ongafika ku-15kWh kugridi nsuku zonke.

2. Imininingwane yephrojekthi

Isicelo

Uhlelo lusebenza ngezindlela ezimbili:

Imodi exhunywe kwigridi:

– Imithwalo yasemini ibeka phambili amandla e-photovoltaic;

– Ukukhiqiza i-PV eningi kuqala kushaja amabhethri okugcina;

– Uma ibhethri selishaje ngokugcwele, amandla e-PV asele angathengiswa kugridi (avalwe ku-15kWh/ngosuku);

Ngesikhathi sasebusuku noma izimo eziguqubele, ukukhishwa kwebhethri kunikeza amandla kuze kube yilapho i-SOC yehla ngaphansi kuka-10%, lapho uhlelo luvala khona bese lushintshela ku-mains supply;

Ukushaja amabhethri avela ku-mains supply akuvunyelwe.

Imodi Yokulinda Engaphandle Kwegridi:

Ngesikhathi sokunqamuka kukagesi, uhlelo lokugcina amandla lushintsha ngokuzenzakalelayo luye ekusebenzeni ngaphandle kwegridi ukuze lunikeze imithwalo ebalulekile;

Uhlelo luyavala uma ukukhishwa kwebhethri kufinyelela ku-SOC < 10%, okuholela ekunqanyulweni komthwalo.

3. Izinzuzo Zephrojekthi

Ukuthuthukiswa Komnotho: Kukhulisa ukuzikhiqiza kanye nokuzisebenzisa ukuze kuncishiswe izindleko zikagesi; kusekela ukuphakelwa kwemali eyengeziwe nsuku zonke ukuze kutholakale imali eyengeziwe.

Ukuphepha Kwamandla: Kuhlinzeka ngamandla okusekelayo angaphandle kwegridi ngesikhathi sokungasebenzi kwe-mains, okuqinisekisa ukusebenza kwesikhashana kwemithwalo ebalulekile.

Ukuhlela Okuhlakaniphile: Kushintsha ngokuzenzakalelayo amasu okushaja/okukhipha ibhethri ngokusekelwe emikhawulweni ye-SOC (10%–100%) ukuze kwandiswe isikhathi sokuphila kwebhethri.

Ukuhambisana Okuphezulu: Izixhumi zokuxhumana ezijwayelekile ezigciniwe zenza kube lula ukuhlanganiswa nezinhlelo ze-PV ezikhona kanye nemishini yokulinganisa igridi.

Ukuzivumelanisa Nezimo Zendawo: I-logic yokulawula eyenziwe ngokwezifiso elungiselelwe ukusetshenziswa okuphansi kwansuku zonke kwamakhasimende (cishe i-14.8kWh) kanye namahora okusebenza, okuvimbela ukuhlinzekwa ngokweqile.
