Commercial and Industrial (C&I) energy storage systems play a crucial role in maximizing the self-consumption rate of solar energy, reducing electricity expenses for industrial and commercial owners, and aiding in energy conservation and emission reduction efforts. These systems are categorized as user-side energy storage solutions, enabling enterprises to optimize their energy usage and become more sustainable.

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.

The structure of C&I energy storage systems typically involves separate Power Conditioning System (PCS) units and battery systems. The inverter boost unit consists of the PCS, grid-connected cabinets, and transformers. Containers housing the battery cabinets, confluence cabinets, and monitoring equipment provide independent power supply, lighting, temperature control, humidity control, fire protection, safety escape, and other automatic control and safety assurance units. Additionally, the power station requires a power system to provide self-consumption power for the energy storage unit and a booster station to facilitate grid connection.

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.

C&I energy storage inverters have a relatively simple function, primarily based on two-way conversion. They are smaller in size and easier to integrate with battery systems. The flexibility of these inverters allows for expansion based on future needs. With an ultra-wide voltage range of 150-750V, they can cater to various battery types such as lead-acid batteries, lithium batteries, and Lithium Iron Phosphate (LEP) batteries. In addition to basic converter functions, coupling functionality is crucial, including primary frequency regulation, fast dispatch of source, grid and load, and strong adaptability to achieve quick power response.

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.

The energy management system (EMS) for most C&I energy storage systems does not require grid dispatching, resulting in relatively basic functionality. The primary focus of the EMS is local energy management, supporting battery balance management, ensuring operational safety, enabling millisecond-level fast response, and facilitating integrated management and centralized control of energy storage subsystem equipment.

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.
