Njira yatsopano yopangira ma microgrids kutengera dzuwa, hydrogen
Kugwiritsa ntchito ma polima polima ma cell a mafuta ngati magetsi obwezeretsa mphamvu mu ma microgrids a dzuwa kumatha kuchepetsa mtengo ndikuwongolera magwiridwe antchito, malinga ndi gulu lapadziko lonse la ofufuza. Iwo apanga njira yatsopano yoyendetsera mphamvu yomwe ingakhale yabwino kwa ma hybrids a dzuwa-hydrogen microgrids kumadera akutali.

Gulu lofufuzira lapadziko lonse lapansi lakhazikitsa njira yatsopano yoyendetsera mphamvu yothandizira kuyang'anira kuchuluka kwa ma microgrid akutali ndi dzuwa omwe amadalira ma hydrogen mafuta cell kuti apange magetsi.
Adawonetsa mtunduwo kudzera pulogalamu ya Transient System simulation program (TRNSYS) pamakina a PV omwe amalumikizidwa ndi mafuta a polymer electrolyte membrane (PEM). Amapereka magetsi ku dongosololi mphamvu yamagetsi ikadutsa mphamvu yopangidwa ndi chomera cha PV. Gulu la 21.4 kW la dzuwa limakhala ndi mphamvu yamagetsi pachaka ya 127.3 kW h / m2 pansi pazikhalidwe zonse.
"Malo onse opangira magetsi a PV ali pafupifupi 205.3 m2, ndi mtundu wa PV wa 100 Wp ndi 1 m2Malo amasankhidwa, "ophunzirawo adatero. "Kutsata kwambiri mphamvu yamagetsi (MPPT) kumagwiritsidwa ntchito pagulu la PV kuti litenge mphamvu yayikulu ya PV."
Electrolyzer idapangidwa ndi mphamvu ya 5 kW, yomwe ingakhale yokwanira kuyamwa magetsi omwe amapangidwa ndi chomera cha dzuwa ndikupanga hydrogen yamafuta amafuta nthawi yamagetsi a PV, gulu lofufuziralo linatero.
'"Mphamvu yamagetsi yamagetsi pamafanizowa inali 90%," adalongosola. Selo limodzi linali ndi mphamvu 1.64 V ya mphamvu ya 220-V, yomwe imafunikira maselo 134. ”

Kuphatikizaku kumatha kutulutsa hydrogen pamipiringidzo isanu ndi iwiri komanso kachulukidwe kakang'ono. Thanki hydrogen anali kakulidwe pa 22 kiyubiki mamita kusunga mafuta onse hydrogen pa mipiringidzo 150. Selo yamafuta inali yayikulu pamphamvu yayikulu yama 3 kW pamitengo yayikulu kwambiri.
Ofufuzawo adachita zoyerekeza pamakina ku Beijing kwa miyezi 12. Ntchito yawo idawonetsa kuti khungu lamafuta limagwira ntchito mokwanira pakati pa Marichi ndi Seputembara, pomwe dongosolo la PV limapanga mphamvu zambiri. Ophunzirawo adati kasinthidwe kake ndi mawonekedwe ake akuwonetsetsa kuti kuchuluka kwa haidrojeni yomwe idadyedwa ikhala yofanana ndi ndalama zomwe zimapangidwa pachaka.
"Zotsatira zimatsimikizira kuti dongosololi linali lokwanira molondola," adatero ofufuzawo. "Njira zonse zogwirira ntchito zikuyerekeza kuti zinali 47.9%, zomwe zinali zochuluka kuposa zomwe zimapezeka m'maphunziro am'mbuyomu ndi kasinthidwe komweko."
Iwo anafotokoza za kayendetsedwe ka kayendetsedwe ka mphamvu mu "Njira yosakanikirana ya hydrogen mafuta yophatikiza ma cell osakanizidwa: Kuwongolera mphamvu ndikukonzekera koyenera, ”Imene inafalitsidwa posachedwapa mu Zolemba za Energy Sustainable.
