Wata ƙungiyar bincike ta duniya ta ɓullo da wata sabuwar dabarar sarrafa makamashi don taimakawa gudanar da aiki mai yawa a cikin ƙananan microgrids masu amfani da hasken rana waɗanda ke dogaro da ƙwayoyin mai na hydrogen don samar da wutar lantarki.
Sun nuna samfurin ta hanyar software na kwaikwayi (TRNSYS) na software akan tsarin PV wanda ke da alaƙa da kwayar polymer electrolyte membrane (PEM). Yana ba da wutar lantarki ga tsarin lokacin da ƙarfin ɗora kaya ya wuce ƙarfin da tsirar PV ke samarwa. Tsarin 24.4 kW na hasken rana yana da yawan ƙarfin shekara shekara na 127.3 kW h / m2 a ƙarƙashin daidaitattun yanayi.
“Yankin gaba daya na tashar wutar lantarkin ya kai kimanin 205.3 m2, kuma samfurin PV na 100 Wp da 1 m2an zabi yankin, ”in ji masana. "Ana amfani da matsakaicin bin diddigin maki (MPPT) a kan tsarin PV don girbe iyakar ƙarfin PV."
An tsara wutan lantarki da karfin 5 kW, wanda zai isa ya sha wutar da hasken rana ya samar kuma ya samar da sinadarin hydrogen na kwayar mai a wasu lokutan na karfin PV, inji kungiyar binciken.
'"Ingancin wutan lantarki a cikin wannan samfurin ya kai kashi 90%,' 'in ji su. "Voltagearfin tantanin halitta ɗaya ya kasance 1,64 V don ƙarfin ƙarfin tarin 220-V, wanda ke buƙatar jimlar sel 134."
