Indlela entsha yokwakha ii-microgrids ngokubhekisele kwilanga, i-hydrogen
Ukusetyenziswa kweeseli zepetroli zombane ze-polymer cell cell njengokugcina amandla kwi-microgrids yelanga kunokuqhuba iindleko kunye nokuphucula ukusebenza, ngokweqela labaphandi bamanye amazwe. Bacebise ngenkqubo entsha yolawulo lwamandla enokuba yeyona ilungele i-hybrid yelanga-hydrogen microgrids kwiindawo ezikude.
Umfanekiso: SMA
Yabelana
Iqela lophando lwamazwe aphesheya liphuhlise isicwangciso esitsha solawulo lwamandla ukunceda ukulawula ngaphezulu kwii-microgrids ezikude zelanga ezixhomekeke kwiiseli zepetroli ye-hydrogen yokwenza amandla okugcina.
Babonisa imodeli ngenkqubo yokulinganisa yeNkqubo yeThutyana (i-TRNSYS) kwinkqubo ye-PV eyayinxulunyaniswe ne-polymer electrolyte membrane (PEM) yeseli yamafutha. Inika umbane kwinkqubo xa amandla omthwalo egqitha kumandla aveliswa sisityalo sePV. Uluhlu lwelanga elingu-21.4 kW linamandla esiveliso sonyaka ayi-127.3 kW h / m2 phantsi kweemeko eziqhelekileyo.
Ummandla opheleleyo weziko lamandla e-PV umalunga ne-205.3 m2, kunye nemodeli yePV ye-100 Wp kunye ne-1 m2indawo iyakhethwa, ”zitshilo izifundiswa. "Elona qondo liphezulu lokulandela umkhondo wamandla (MPPT) lisetyenziswa kuludwe lwe-PV ukuvuna ubuninzi bamandla ePV."
I-electrolyzer yayilelwe ngomthamo we-5 kW, eya kuthi yanele ukufunxa umbane oveliswa sisityalo selanga kunye nokuvelisa i-hydrogen yeseli yeoyile ngamanye amaxesha amandla e-PV, iqela lophando lathi.
"Ukusebenza kombane kule modeli bekuyi-90%," bachaze. "Umbane weseli enye wawuyi-1.64 V ye-220-V yokubeka amandla ombane, efuna iiseli ezili-134 zizonke."
Umxholo odumileyo
Olu dibana luyakwazi ukuvelisa i-hydrogen kwimivalo esixhenxe kunye noxinano oluphezulu. Itanki le-hydrogen lalilinganiswe nge-22 cubic metres ukugcina yonke imveliso ye-hydrogen kwii-150 bar. Iseli yeoyile yayilinganiswe kwinqanaba lomthamo wamandla ophakamileyo we-3 kW kwimithwalo ephezulu.
Abaphandi baqhuba ukulinganisa kwinkqubo eBeijing kwisithuba seenyanga ezili-12. Iprojekthi yabo ibonakalise ukuba iseli yezibaso isebenza ngokuzeleyo phakathi kuka-Matshi noSeptemba, xa inkqubo ye-PV yayinemveliso yamandla ephezulu. Abahlohli bathi ukucwangciswa kwenkqubo ecetywayo kunye nobungakanani bayo buqinisekisa ukuba isixa sonyaka sehydrogen esisetyenzisiweyo siyakulingana nesixa sonyaka esivelisiweyo.
"Iziphumo ziqinisekisa ukuba le nkqubo yayilinganiswe ngokuchanekileyo," utshilo abaphandi. "Inkqubo yokusebenza iyonke yaqikelelwa ukuba yi-47.9%, eyayiphezulu kunaleyo yayifunyenwe kwizifundo zangaphambili ngoqwalaselo olunye."
Bachaze inkqubo yolawulo lwamandla “Inkqubo esebenzayo ye-photovoltaics-edityanisiweyo ye-hydrogen yeseli esekwe kwiseli: Ulawulo lwamandla kunye noqwalaselo olufanelekileyo, ”Ebesandula ukupapashwa kwiphepha le- Ijenali yaMandla aZinzileyo.
