Izinhlelo zokugcina amandla ezentengiselwano nezezimboni (C&I) zidlala indima ebalulekile ekwandiseni izinga lokusebenzisa wena ngokwakho amandla elanga, ekwehliseni izindleko zikagesi kubanikazi bezimboni nabezentengiselwano, kanye nokusiza ekongeni amandla kanye nemizamo yokunciphisa ukungcola. Lawa masistimu ahlukaniswa njengezixazululo zesitoreji samandla sohlangothi lwabasebenzisi, okuvumela amabhizinisi ukuthi athuthukise ukusetshenziswa kwawo kwamandla futhi abe nokusimama.

Kunamamodeli ebhizinisi amabili ayinhloko okusebenzisa amasistimu okugcina amandla e-C&I. Kwimodeli yokuqala, abasebenzisi bezentengiselwano nabezimboni bazifaka ngokwabo okokugcina amandla, okuholela ekongeni kwezindleko zikagesi eziqondile. Kodwa-ke, laba basebenzisi kufanele bathwale izindleko zokuqala zokutshala izimali kanye nezindleko zonyaka zokulungisa. Imodeli yesibili ihlanganisa izinkampani zesevisi yamandla ezisiza abasebenzisi ohlelweni lokufaka. Lezi zinkampani zitshala imali ekwakheni impahla yokugcina amandla futhi zinesibopho sokusebenza nokunakekelwa kwezinhlelo. Abasebenzisi bezimboni nabezentengiselwano babe sebekhokhela izinkampani ezihlinzeka ngogesi ngezindleko zabo zikagesi.

Ukusetshenziswa kwezinhlelo zokugcina amandla ohlangothini lwabasebenzisi kukhule kakhulu, okuhlanganisa izimo ezihlukahlukene ezifana neziteshi zokushaja nokushintshanisa, izikhungo zedatha, iziteshi eziyisisekelo ze-5G, amandla ogu lolwandle, kanye nokushintshashintsha kwamaloli amakhulu. Lezi zinhlelo sezibalulekile ekuvumeleni lezi zikhungo ukuthi zisebenze kahle ngenkathi zinciphisa umthelela wazo kwezemvelo.

Isakhiwo sezinhlelo zokugcina amandla e-C&I ngokuvamile sibandakanya amayunithi ahlukene we-Power Conditioning System (PCS) namasistimu ebhethri. I-inverter boost unit iqukethe i-PCS, amakhabethe axhunywe kugridi, nama-transformer. Iziqukathi ezigcina amakhabethe ebhethri, amakhabethe ahlanganayo, kanye nemishini yokuqapha inikeza amandla azimele, ukukhanya, ukulawula izinga lokushisa, ukulawula umswakama, ukuvikela umlilo, ukuphunyuka kokuphepha, namanye amayunithi okulawula okuzenzakalelayo nokuqinisekisa ukuphepha. Ukwengeza, isiteshi sikagesi sidinga isistimu yamandla ukuze sinikeze amandla okuzisebenzisela iyunithi yokugcina amandla kanye nesiteshi esikhuthazayo ukuze kube lula ukuxhuma kwegridi.

Amaphaneli elanga akha ingxenye ebalulekile yezinhlelo zokugcina amandla e-C&I. Idizayini yazo kufanele ihlangabezane nesidingo sansuku zonke sokusetshenziswa kukagesi komthwalo ngaphansi kwezimo zezulu ezimaphakathi. Lokhu kusho ukuthi amandla akhiqizwa amaphaneli elanga kufanele afane nomthwalo osetshenziswa minyaka yonke ugesi. Kodwa-ke, kubalulekile ukucabangela ukuthi akuwona wonke amandla akhiqizwayo aguqulwa abe ukusetshenziswa kukagesi. Izinto ezifana nokusebenza kahle kwesilawuli, ukulahlekelwa komshini, nokulahlekelwa kwephakethe lebhethri ngesikhathi sokushaja nokukhipha kufanele kubalwe.

Uma kubhekwa izidingo zesikhathi sokuphendula eziphansi uma kuqhathaniswa zezinhlelo zokugcina amandla e-C&I, amabhethri ohlobo lwamandla avame ukusetshenziswa ngenxa yokusebenza kahle kwezindleko, impilo yomjikelezo, nesikhathi sokuphendula. Umsebenzi oyinhloko webhethri ukuqinisekisa ukusetshenziswa kwamandla okungaphazamiseki lapho imisebe yelanga inganele. Umthamo wephakethe lebhethri ungaklanywa ngokuya ngezidingo nezimo ezithile zesistimu ngayinye, kucatshangelwa izici ezifana nezidingo ze-voltage, amashifu esikhathi samandla, i-peak-valley arbitrage, namandla okulondoloza izinsuku zemvula.

Iziguquli zesitoreji samandla ze-C&I zinomsebenzi olula uma kuqhathaniswa, ngokuyinhloko osuselwe ekuguquleni ngezindlela ezimbili. Mancane ngosayizi futhi kulula ukuwahlanganisa namasistimu ebhethri. Ukuguquguquka kwalawa ma-inverters kuvumela ukwanda ngokusekelwe ezidingweni zesikhathi esizayo. Ngobubanzi be-ultra-wide voltage range of 150-750V, angakwazi ukubhekana nezinhlobo zebhethri ezihlukahlukene njengamabhethri e-lead-acid, amabhethri e-lithium, namabhethri e-Lithium Iron Phosphate (LEP). Ngokungeziwe emisebenzini eyisisekelo yesiguquli, ukusebenza kokuhlanganisa kubalulekile, okuhlanganisa ukulawulwa kwemvamisa okuyinhloko, ukuthunyelwa okusheshayo komthombo, igridi nomthwalo, kanye nokuzivumelanisa nezimo okuqinile ukuze kuzuzwe impendulo esheshayo yamandla.

Lapho kukhethwa i-PCS, kufanele kucatshangelwe izidingo zomthwalo. Imithwalo ngokuvamile ihlukaniswa njenge-inductive noma ukumelana. Imithwalo ye-inductive, njengamamotho atholakala kuma-air conditioner amaphakathi, ama-compressor, nama-cranes, inamandla okuqalisa aphindwe kathathu kuya kahlanu amandla akaliwe. Ngakho-ke, kuyadingeka ukucabangela amandla okuqala ale mithwalo ngesikhathi sokusebenza ngaphandle kwegridi esigabeni sokuklama ukuze kuqinisekiswe ukuthi amandla okukhipha inverter adlula izidingo zamandla omthwalo. Kuzinhlelo zokusebenza ezinezidingo eziqinile, ezifana neziteshi zokuqapha nezokuxhumana, amandla aphelele okukhiphayo kufanele kube isamba sawo wonke amandla okulayisha.

Isistimu yokuphatha amandla (EMS) yezinhlelo eziningi zokugcina amandla e-C&I ayidingi ukuthunyelwa kwegridi, okuholela ekusebenzeni okuyisisekelo uma kuqhathaniswa. Okugxilwe kakhulu kwe-EMS ukuphatha amandla endawo, ukusekela ukuphathwa kwebhalansi yebhethri, ukuqinisekisa ukuphepha kokusebenza, ukunika amandla impendulo esheshayo yezinga le-millisecond, nokwenza lula ukuphathwa okudidiyelwe kanye nokulawulwa okumaphakathi kwemishini yesistimu engaphansi yokugcina amandla.

Uma sibheka phambili, isikhathi esisuka ku-2023 kuya ku-2024 kulindeleke ukuthi sibe nenani eliphakeme elisha ekuthuthukisweni kwendawo yokugcina amandla ezimbonini nezohwebo. Isidingo sezinhlelo ezinjalo, ngaphakathi nangaphandle, sibalulekile. Nakuba iphethini yokuncintisana ingakaveli ngokugcwele, imakethe iseduze nekhefu. Ukugcinwa kwamandla ezimbonini nezohwebo kunamandla okuba ukumiswa okujwayelekile emikhiqizweni yezimboni nasezifundeni ezinkulu zezentengiselwano, kube nendawo eyanele yokukhula.

I-ACDC, inkampani egxile ocwaningweni nasekuthuthukisweni, isilandele eduze isidingo semakethe samabhethri okugcina amandla. Ukusabela kulesi sidingo, i-ACDC izokhipha uchungechunge lwamabhethri okugcina amandla ezimbonini nawezohwebo. Lezi zixazululo ezintsha zizohlinzeka ngokunwebeka okumodulayo nokuvumelana nezimo kumazinga ahlukahlukene wamandla namandla, kunikeze idizayini ehlangene-konke ehambisanayo yokuhlanganisa i-AC. Amabhethri e-ACDC azofaniswa ngokuphelele nezidingo ezithile zamandla, okwandisa impilo yebhethri. Njengoba kunezindlu zangaphandle ezilungele noma iyiphi indawo yokufaka, iphothifoliyo ebanzi ye-ACDC yezisombululo zokugcina amandla ivumela ukusatshalaliswa okuphumelelayo nokungabizi kanye nokusetshenziswa kwamandla ngokuvumelana nezidingo zokusebenza. Amasistimu abo ochwepheshe kanye namathimba ezicelo asebenzisa amathuluzi akhethekile e-techno-economic ukuthuthukisa umnotho wesikhathi sonke samaphrojekthi, ukuhlinzeka ngebhizinisi lezinga lokutshala izimali elisekela ukuhlelwa kwephrojekthi nokuxhaswa ngezimali. I-ACDC izibophezele ekusekeleni amaklayenti ayo kuzo zonke izinyathelo zohambo lwawo lokugcina amandla.
