1. Uhlolojikelele lwephrojekthi

This project is located in Ghana, Africa, and serves as a commercial demonstration site integrating solar power generation, battery energy storage, and electric vehicle charging. Designed for EV charging operations, the station has become a regional showcase for clean-energy applications.

I-transformer yendawo inamandla okusebenzisa kuphela 120, XNUMX kVANgenxa yomthamo wegridi olinganiselwe kanye nokucima kukagesi okuvamile, ukuphakelwa kwegridi okukhona akukwazi ukusekela zonke iziteshi zokushaja ezisebenza ngamandla aphelele, okunciphisa kakhulu umthamo wokushaja wesiteshi kanye nokusebenza kahle kwaso.

Ukuze kulungiswe kokubili umthamo wegridi onganele kanye nokunikezwa kwamandla okungathembekile, ikhasimende likhethe i- Ikhabethe lokugcina amandla lebhethri elingu-125 kW/261 kWh, kuhlanganiswe ne Iswishi yokudlulisa engaguquki ye-STS kanye nohlelo lwe-photovoltaic carport.

Ngaphansi kwezimo ezijwayelekile zegridi, uhlelo lwelanga, uhlelo lokugcina ibhethri, kanye negridi yokusetshenziswa kusebenza ndawonye ukusekela imishini yokushaja ngamandla aphelele. Uma kwenzeka igridi ingasebenzi, uhlelo luqeda ushintsho kusuka ekusebenzeni okuxhunywe kugridi kuya ekusebenzeni okungaphandle kwegridi ngaphakathi komzuzwana owodwa. Amashaja asheshayo e-DC anamandla aphezulu ayavalwa okwesikhashana, kuyilapho uhlelo luqhubeka nokunikeza amandla emishini yokushaja ye-AC cishe isikhathi esingange Amahora we-5-8, ukuqinisekisa ukuthi izinsizakalo zokushaja ezibalulekile zihlala zitholakala.

2. Imininingwane Yephrojekthi

Isicelo se2.1

Le phrojekthi iyisicelo esijwayelekile sezentengiselwano sesistimu yokushaja ye-solar-storage-EV ehlanganisiwe.

Isiteshi sokushaja eGhana sibhekane nezinselelo ezintathu ezinkulu:

• Isidingo sokushaja esiphezulu kakhulu
• Umthamo wegridi yendawo ulinganiselwe
• Ukunikezwa kwamandla kagesi okusetshenziswayo okungathembekile

Ukuthembela kuphela kugridi yokusetshenziswa kwemishini akukwazanga ukusekela yonke imishini yokushaja esebenza ngasikhathi sinye. Ukuthuthukiswa komthamo we-transformer okuvamile bekuzodinga ukutshalwa kwezimali okukhulu kanye nenqubo ende yokwakha nokugunyaza.

I-carport ye-photovoltaic ikhiqiza ugesi ohlanzekile ngqo endaweni, kuyilapho uhlelo lokugcina amandla ebhethri lugcwalisa igridi ngezikhathi zesidingo esikhulu sokushaja. Uhlelo luphinde lunikeze ukushintsha okusheshayo okuphuthumayo ngesikhathi sokungasebenzi kwegridi.

Lesi sixazululo sisekela ukusebenza kokushaja umthwalo ogcwele ngaphansi kwezimo ezijwayelekile ngenkathi sigcina izinsizakalo zokushaja ezibalulekile ngesikhathi sokuphazamiseka kukagesi. Sinciphisa ukuncika kugesi osetshenziswayo, sehlisa izindleko zokusebenza, futhi sifaneleka kakhulu eziteshini zokushaja ze-EV zezentengiselwano ezifundeni zase-Afrika ezinegridi kagesi ebuthakathaka noma engazinzile.

3. Izinzuzo Eziyinhloko Zephrojekthi

3.1 Overcomes Grid Capacity Limitations

Uhlelo lokugcina amandla oluyi-125 kW/261 kWh lugcwalisa ukuphakelwa okulinganiselwe kwezinsizakusebenza, okuvumela isiteshi sokushaja ukuthi sisebenze ngokuthembekile naphezu komthamo olinganiselwe we-transformer ekhona engu-120 kVA.

3.2 Coordinated Solar, Storage, and Grid Operation

Uhlelo lwe-photovoltaic, uhlelo lokugcina ibhethri, kanye negridi yokusetshenziswa kusebenza ndawonye ngobuhlakani ukusekela isidingo sokushaja. Lokhu kwandisa ukusetshenziswa kwamandla elanga ahlanzekile futhi kunciphisa ugesi othengwa kugridi.

3.3 Continuous Operation During Power Outages

I-STS ivumela ukushintsha okusheshayo okuxhunywe kugridi kanye nokungashintshi kwegridi. Ngesikhathi sokungasebenzi, uhlelo lungaqhubeka nokuhlinzeka ngemishini yokushaja i-AC cishe amahora angu-5-8, okuqinisekisa ukuthi izinsizakalo zokushaja ezibalulekile zihlala zisebenza.

3.4 Lower Infrastructure and Operating Costs

Isixazululo sigwema izindleko eziphezulu kanye nesikhathi eside sokusetshenziswa esihambisana nokuthuthukisa i-utility transformer. Ukusetshenziswa kwamandla elanga, ukwesekwa komthwalo ophezulu, kanye nokugcinwa kwamandla nakho kusiza ekunciphiseni izindleko zikagesi zesikhathi eside kanye nokusebenza kwesiteshi.
