1. Uhlolojikelele lwephrojekthi

Lo msebenzi utholakala eGhana, e-Afrika, futhi usebenza njengendawo yokubonisa ezentengiselwano ehlanganisa ukukhiqizwa kwamandla elanga, isitoreji samandla ebhethri, kanye nokushaja izimoto zikagesi. Njengoba yakhelwe imisebenzi yokushaja i-EV, lesi siteshi sesibe umbukiso wesifunda wezinhlelo zokusebenza zamandla ahlanzekile.

I-transformer yokusetshenziswa kwendawo inomthamo we- 120 kVA kuphela . Ngenxa yomthamo wegridi olinganiselwe kanye nokuphazamiseka kukagesi okuvamile, ukuhlinzekwa 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 ikhabethe lethu lokugcina amandla lebhethri elingu-125 kW/261 kWh , elihlanganiswe neswishi yokudlulisa emile ye-STS kanye nesistimu ye-carport ye-photovoltaic.

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 amahora angu-5-8 , okuqinisekisa 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 Inqoba Ukulinganiselwa Kwamandla Egridi

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 Ukusebenza Okuhlanganisiwe Kwelanga, Isitoreji, kanye Negridi

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 Ukusebenza Okuqhubekayo Ngesikhathi Sokucima Kukagesi

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 Izindleko Eziphansi Zengqalasizinda kanye Nezokusebenza

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.
