I-Bottleneck yeGrid: Kungani Amaphrojekthi Okushaja Amandla Aphezulu Ema

Umqhubi wemikhumbi eningizimu yeJalimane wayefuna amashaja asheshayo angu-12 × 180 kW DC endaweni yokugcina izinto. Ucwaningo lwezinsiza lubuye nenombolo eqinile: i-transformer ekhona engu-630 kVA yayingasekela kuphela umthwalo owengeziwe ongu-400 kW ngaphandle kokuqinisa. Isilinganiso sokuthuthukisa sasingu-€180,000 ngesikhathi sokuhola sezinyanga ezingu-14. Umqhubi wayenezinketho ezimbili: ukunciphisa iphrojekthi ibe amashaja amane, noma ukuthola indlela yokwenza igridi isebenze kanzima.

Lowo mqhubi akahlukile. Kuyo yonke iYurophu, eNyakatho Melika, nase-Asia-Pacific, amanethiwekhi okusabalalisa aklanyelwe imithwalo yezindlu neyokuhweba elula, hhayi amaqoqo ezimoto ezidonsa i-150-600 kW ngayinye. Abaqhubi bezinhlelo zokusabalalisa (ama-DSO) eJalimane kuphela babika ukusilela komugqa weminyaka eminingi wokuxhumeka kwezentengiselwano, futhi izifundo ezenziwa ngabalawuli begridi kazwelonke zikhomba ngokuphindaphindiwe ukushaja okusheshayo komphakathi njengenye yemithombo emisha emikhulu yomthwalo kuze kube ngu-2030. I-physics ilula: amandla okushaja kumele avela ndawana thile, futhi uxhumano lwegridi luyipayipi elingokoqobo.

Umphumela uba ukuthi umthamo wegridi, hhayi ukutholakala kweshaja, manje usunquma ukuthi iphrojekthi ingenzeka yini. Imingcele emithathu yesakhiwo ibusa:

1. Imikhawulo ye-transformer kanye ne-feeder— i-substation yendawo noma i-transformer efakwa ku-pad inesilinganiso somthamo oqinile; ukuyidlula kukhubaza imishini yokuvikela noma kwehlisa impilo yempahla. 2.Izindleko zokuxhuma nokuqinisa— ukuthuthukiswa kwezinsiza kusebenza kudinga imali eningi futhi kuvame ukukhokhiswa ngokugcwele kumfakisicelo. 3.Izikhathi zokuhola zokuxhumanisa— izifundo, izimvume, kanye nolayini bokwakha kuvame ukusunduza amaphrojekthi izinyanga eziyi-12-24 ngaphezu kosuku lokulethwa kwabashaja.

Indlela Isiteshi Sokushaja se-BESS Esisusa Ngayo Uphahla Lomthamo

Isiteshi sokushaja se-BESS sifaka ibhethri phakathi kokuxhumeka kwegridi kanye nehadiwe yokushaja. Ngesikhathi samahora angekho esicongweni - ngokuvamile ebusuku, noma emini emagridini anamandla elanga - ibhethri lishaja kusuka kugridi ngesivinini esiphansi nesizinzile. Ngesikhathi semicimbi yokushaja, ibhethri liphuma kanye negridi, ngakho isiteshi singanikeza amandla okushaja angu-240 kW noma angu-480 kW kuyilapho uxhumano lwegridi ludonsa kuphela i-100-150 kW.

Lo mklamo ushintsha i-equation yephrojekthi ngezindlela ezine ezilinganiswayo:

• Ukunciphisa usayizi woxhumano.Indawo edinga ukushaja okungu-600 kW ngesikhathi esisodwa ingahlinzekwa ngoxhumano lwegridi engu-200 kW kanye nebhethri elingu-400 kWh–1 MWh, kuye ngamaphrofayili weseshini.
• Ukuhlehliswa kwe-transformer.Uma i-transformer ekhona ingamboza umthwalo ojwayelekile kodwa hhayi i-peak, indawo yokugcina isitoreji imunca i-peak futhi akudingeki ukuthuthukiswa.
• Ukwehliswa kwezindleko zesidingo.Izindleko zezentengiselwano zikhokhisa isidingo esiphezulu ngezikhawu zemizuzu eyi-15; ibhethri eligunda lezo ziqongo linciphisa ngqo into yomugqa wokushaja wesidingo.
