Methodzọ ọhụrụ iji wuo microgrids dabere na anyanwụ, hydrogen
Ojiji nke polymer electrolyte akpụkpọ ahụ mmanụ ọkụ dị ka ike nchekwa nchekwa na microgrids nke anyanwụ nwere ike ime ka ọnụ ahịa kwalite ma melite arụmọrụ, dịka otu ndị na-eme nchọpụta si mba ụwa si kwuo. Ha atụpụtala usoro njikwa ike ọhụụ nke nwere ike ịdị mma maka ngwakọ microgrids-hydrogen microgrids n'ime ebe dịpụrụ adịpụ.

Otu ndi oru nyocha nke mba uwa eweputara atumatu oru ike ohuru iji nyere aka jikwaa akuku na microgrids di anya nke na-adabere na sel nke mmanu hydrogen maka ike ike.
Ha gosipụtara ihe nlere ahụ site na mmemme ngwanrọ nke usoro (TRNSYS) na sistemụ PV nke ejikọtara na polymer electrolyte membrane (PEM). Ọ na-enye ọkụ eletrik na sistemụ ahụ mgbe ike ibu karịrị ike sitere na osisi PV. Ngwongwo nke 21.4 kW nke ozo nwere ikike ikike kwa afọ nke 127.3 kW h / m2 n'okpuru ọnọdụ ọkọlọtọ.
“Mkpokọta ebe ọkụ ọkụ PV dị ihe dịka 205.3 m2, na ụdị PV nke 100 Wp na 1 m2A hoputara mpaghara, ”ka ndị mmụta ahụ kwuru. "Oke kacha ike mgbe nsuso (MPPT) na-etinyere na PV n'usoro na ihe ubi kacha PV ike."
Emere electrolyzer nwere ikike nke 5 kW, nke ga-ezuru iji nweta ọkụ eletrik nke sitere na mbara igwe na-ewepụta ma mepụta hydrogen maka mmanụ mmanụ n'oge nke ike PV oge, otu ndị ọrụ nyocha ahụ kwuru.
'”Nrụpụta electrolyzer na ụdị a bụ 90%,” ka ha kọwara. “Voltage nke otu mkpụrụ ndụ bụ 1.64 V maka voltaji 220-V, nke chọrọ mkpokọta mkpụrụ ndụ 134.”
Ihe ewu ewu
Nchikota a nwere ike imepụta hydrogen na ogwe asaa na oke njupụta. A na-ahazi tankị ahụ na 22 cubic mita iji chekwaa mmepụta mmiri niile na Ogwe 150. A na-ahazi cell mmanụ ọkụ na ọnụego ike kachasị elu nke 3 kW maka ibu dị elu.
Ndị nyocha ahụ mere nyocha ahụ na sistemụ na Beijing n'ime ọnwa 12. Ọrụ ha gosipụtara na sel mmanụ ụgbọ ala na-arụ ọrụ zuru oke n'etiti Machị na Septemba, mgbe usoro PV nwere mmepụta ume dị elu. Ndị gụrụ akwụkwọ na-ekwu na nhazi usoro a na-ahazi na nha anya hụrụ na hydrogen na-eri kwa afọ ga-adị ka ego a na-eme kwa afọ.
"Nsonaazụ ahụ na-enyocha na usoro ahụ buru ibu nke ọma," ka ndị nnyocha ahụ kwuru. E mere atụmatụ na usoro arụmọrụ zuru oke bụ 47.9%, nke dị elu karịa nke enwetara n'ọmụmụ ihe gara aga na otu nhazi ahụ. "
Ha kọwara usoro njikwa ike na “Oru oma fotovoltaics-jikọtara hydrogen mmanụ sel sistemụ ngwakọ: njikwa ike na nhazi ezigbo, ”Nke e bipụtara na nso nso a na Akwụkwọ akụkọ nke Sustainable Energy.
