Uma siqhathanisa imboni yokulondoloza amandla echumayo nomqhele wethrekhi entsha yamandla, khona-ke isitoreji samandla sezimboni nezohwebo singabhekwa njengegugu kulowo mqhele. E-China, amathuba okukhula kanye namathuba emakethe okugcinwa kwamandla ezimbonini nawezohwebo adlula kude lawo esitoreji esikhulu kanye nokugcinwa kwamandla ekhaya.

Ukugcinwa kwamandla ezimbonini nezohwebo sekuphenduke umkhakha okhula ngokushesha kakhulu wemboni yokugcina amandla, ngenxa yokwehluka kwentengo ephezulu kuya esigodini kulo lonke elaseShayina, okuholele ekwehleni kwezindleko zamabhethri e-lifepo4. Ngenxa yalokho, Izinga Langaphakathi Lokubuyisela (IRR) lokugcinwa kwamandla ezimbonini nezohwebo liye lakhula kancane kancane, okwenza kube inketho ephumelelayo ngokomnotho.

Uma kukhulunywa ngezidingo zokulawula uhlelo, isitoreji samandla sezimboni nesokuhweba sihluke kakhulu kwezinye izinhlobo zokugcina amandla. Isibonelo, ukugxilwa kwesitoreji samandla ezimbonini nezokuhweba kusezindleko kanye nenani lemijikelezo yokushaja nokukhipha, kunesivinini sokuphendula. Ngakho-ke, amabhethri ohlobo lwamandla, ahlala isikhathi eside futhi anesidingo sezinga eliphansi, akhethwa ngaphezu kwamabhethri ohlobo lwamandla abamba iqhaza kumasevisi asiza amandla.

Inhlawulo yokuphatha yezinhlelo zebhethri ezigcina amandla ezimboni nezohwebo azidingi amasu e-hierarchical ayinkimbinkimbi, futhi amanye ama-Power Conversion Systems (PCS) anokusebenza okwakhelwe ngaphakathi kwe-Battery Management System (BMS). I-PCS endaweni yokugcina amandla ezimbonini kanye neyokuhweba ilula kakhulu kunaleyo yokugcina amandla amakhulu futhi kulula ukuyihlanganisa nesistimu yebhethri. Iphinde ifaneleke kangcono izidingo zokuxhumanisa uchungechunge-parallel futhi inokuguquguquka okuqinile nokuhlanganisa ama-inverters e-photovoltaic asabalalisiwe.

Imithombo yemali engenayo yokugcina amandla ezimbonini nezohwebo ihlukene. Nakuba ukusatshalaliswa nokugcinwa kwamandla amasha kuncike kakhulu ekuxhunyweni kwegridi nasekunciphiseni ukuncishiswa, ukugcinwa kwamandla ezimbonini nezohwebo kungangenisa imali ngezindlela ezihlukahlukene njengokuqashisa amandla, izinsiza ezisiza amandla, i-peak-valley difference arbitrage, kanye nesinxephezelo somthamo. Ngakho-ke, inani lokugcinwa kwamandla ezimbonini nezohwebo liyi-multi-dimensional.

Isitoreji samandla ezimbonini nesokuhweba sibone ukwanda okukhulu kwesidingo ngenxa yezisusa ezinhle, okuhlanganisa ukuthuthukiswa kwezinqubomgomo zentengo kagesi wesikhathi sokusebenzisa kanye nokwehlukana kwentengo okwandayo ukusuka esigodini ukuya kwesinye. Ukuze kuhlangatshezwane nezindleko zikagesi ezikhuphukayo ezilethwa ukuncishiswa kwamandla okushisa aphezulu kanye nokwabelana ngentengo kagesi olahlekelwa inzuzo, isidingo sokusatshalaliswa kwamandla kagesi we-photovoltaic kanye nezimboni nezohwebo senyuke kuphela.

Ngaphezu kwalokho, izinguquko zakamuva emananini kagesi osetshenziswa ngesikhathi zenze ngcono ukuhlukaniswa kwamahora aphezulu. Isibonelo, e-Sichuan, amahora aphakeme kakhulu ekuseni akhushulwe afinyelela kwamabili, okuvumela isitoreji samandla ezimbonini nezohwebo ukufeza ukushaja okuphindwe kabili nokukhipha amandla, ngaleyo ndlela kuthuthukiswe umnotho wokutshalwa kwezimali kokugcina amandla.

Isitoreji samandla embonini nesokuhweba sinezinhlobonhlobo zezimo zohlelo lokusebenza, okwenza kube nezinto ezihlukahlukene kakhulu uma kuqhathaniswa nesitoreji esikhulu. Ingasetshenziswa ezimbonini zezimboni, izakhiwo zezentengiselwano, amapaki, izikhungo zedatha, iziteshi eziyisisekelo, iziteshi zokushaja izimoto zikagesi (EV), kanye nezindawo zezimayini/izinkundla zikawoyela. Ngenani elikhulayo leziteshi zokushaja ze-EV ekusetshenzisweni kukagesi womphakathi, isidingo sokumisa ukugcinwa kwamandla kulezi ziteshi siyakhula. Ngo-2030, ingxenye yezimoto zikagesi ezishajwa umphakathi ekusetshenzisweni kukagesi womphakathi kulindeleke ukuthi yenyuke izikhathi ezingama-24, ifinyelele ku-4%. Izinga lokugcinwa kwamandla eziteshini zokushaja eChina kulindeleke ukuthi lifinyelele ku-23GW ngo-2025, ngesilinganiso sokutshala imali esicishe sibe izigidigidi eziyi-100 zama-RMB. Ngonyaka wezi-2030, lezi zibalo zizokwenyuka ziye ku-243GW kanye nangaphezulu kwezigidigidi ezingama-RMB ezingama-870, ngokulandelana. ICompound Annual Growth Rate (CAGR) kusukela ngo-2023 kuya ku-2030 ilinganiselwa kuma-64%. Ngakho-ke, ukushaja kwesitoreji selanga kulindeleke ukuthi kube ukucushwa okujwayelekile kweziteshi zokushaja, kube nomthelela emandleni emakethe yama-trillion-dollar yokugcina amandla ezimboni nezohwebo.

Izosuswa uma yephula umthetho
