Txoj kev tshiab los tsim microgrids raws li hnub ci, hydrogen
Kev siv cov polymer electrolyte membrane roj hlwb los ua kev tsim hluav taws xob hauv hnub ci microgrids tuaj yeem tsav tus nqi qis thiab txhim kho kev ua tau zoo, raws li pawg neeg tshawb fawb thoob ntiaj teb. Lawv tau tawm tswv yim txog kev tswj lub zog tshiab uas tuaj yeem yog qhov zoo rau cov hnub ci-hydrogen microgrids nyob rau hauv cov chaw deb.

Pab pawg neeg tshawb fawb thoob ntiaj teb tau tsim lub tswv yim tswj kev siv hluav taws xob tshiab kom pab tswj hwm kev siv nyiaj ntau tshaj hauv cov hnub ci microgrids uas vam khom rau cov roj hydrogen hydrogen ua haujlwm rau kev tsim hluav taws xob.
Lawv pom tias tus qauv dhau los ntawm Transient System sim program (TRNSYS) software ntawm PV system uas tau txuas nrog lub polymer electrolyte membrane (PEM) roj cell. Nws muab hluav taws xob rau lub kaw lus thaum lub zog ntsaws siab tshaj qhov hluav taws xob tau tsim los ntawm PV cog. Lub 21.4 kW hnub ci ci tau siv hluav taws xob txhua xyoo ntawm 127.3 kW h / m2 nyob rau hauv cov qauv kev cai.
“Thaj tsam ntawm PV cog rau tag nrho cov nroj tsuag yog kwv yees li 205.3 m2, thiab tus qauv PV ntawm 100 Wp thiab 1 m2cheeb tsam yog xaiv, ”tus kws qhia ntawv hais. "Qhov siab tshaj qhov taw tes rau lub zog tswj (MPPT) tau thov rau PV array kom sau qhov siab tshaj plaws PV zog."
Lub tshuab hluav taws xob tau tsim nrog lub zog ntawm 5 kW, uas yuav txaus kom nqus tau cov hluav taws xob uas tsim los ntawm lub hnub ci cog thiab tsim hydrogen rau cov roj ntawm cov roj ntawm lub sijhawm hluav taws xob PV lub zog, pawg tshawb fawb hais tias.
Lawv hais tias "" Lub tshuab roj hluav taws xob zoo hauv cov qauv no yog 90%, "lawv tau piav qhia. "Qhov ntsuas hluav taws xob ntawm ib qho xov tooj ntawm tes yog 1.64 V rau 220-V pawg voltage, uas yuav tsum muaj tag nrho 134 hlwb."
Cov ntsiab lus nrov
Qhov sib xyaw ua ke no tuaj yeem tsim cov tshuaj hydrogen hauv xya kab thiab nrog qhov ntsuas kub. Lub taub ntim dej hydrogen yog qhov loj me ntawm 22 cubic metres los khaws txhua qhov kev tsim tawm hydrogen hauv 150 tuav. Lub roj hluav taws xob tau loj me me ntawm qhov siab kawg ntawm lub zog hluav taws xob ntawm 3 kW rau cov khoom siv sab kawg.
Cov kws tshawb nrhiav tau sim cov simulations rau ib qhov system hauv Beijing tshaj li 12 lub hlis. Lawv qhov project pom tias cov roj hluav taws xob ua haujlwm ntawm tag nrho cov peev txheej thaum Lub Peb Hlis thiab Cuaj Hlis, thaum lub kaw lus PV tau muaj zog ntau dua. Cov kws qhia ntawv tau hais tias cov kev teeb tsa qhov kev thov haujlwm tsim thiab ua kom ntseeg tau tias txhua xyoo ntawm hydrogen uas tau siv yuav tsum yog tib yam li cov nyiaj txhua xyoo uas tau tsim tawm.
Cov kws tshawb fawb tau hais tias "Qhov ntsuas tau lees paub tias lub kaw lus tau pom tseeb me me," cov kws tshawb nrhiav tau hais tias. "Tag nrho cov txiaj ntsig ntawm kev siv hluav taws xob tau kwv yees li 47.9%, uas yog siab dua qhov tau txais hauv kev tshawb fawb yav dhau los nrog kev teeb tsa zoo ib yam."
Lawv piav qhia lub zog tswj kav hauv “Kev siv photovoltaics-ua ke nrog cov roj hydrogen ua ke ntawm cov roj hluav taws xob: tsim kev tswj lub zog thiab kev teeb tsa zoo tshaj plaws, ”Uas nyuam qhuav luam tawm hauv Phau Ntawv Maumoos Phau Ntawv Sau Cov Muaj Zog Kev Ncaj Ncees.
