Njengoba amandla omoya nelanga akhula ngokushesha kuwo wonke amagridi kagesi omhlaba, imvelo yezikhawu yalezi zinsiza idala izinselele ezintsha kubasebenzisi begridi. Ngokungafani nezitshalo zamandla ezivamile ezingakhuphuka noma zehle ngokufunwa, ukukhiqizwa okuvuselelekayo kuncike esimweni sezulu kanye nesikhathi sosuku. Lapha kulapho isitoreji sebhethri sesikali esisetshenziswayo iba yinto esemqoka. Ngokuthatha amandla amaningi avuselelekayo lapho ukunikezwa kudlula isidingo futhi kukhishwe lapho ilanga lishona noma umoya uhamba kancane, ukugcinwa kwebhethri kwesilinganiso esisetshenziswayo sivala igebe phakathi kokukhiqiza nokusetshenziswa. Ngaphezu kwalokho, lezi zinhlelo zihlinzeka ngezinsizakalo zegridi ezibalulekile njengokulawula imvamisa, ukwesekwa kwamandla kagesi, nokukhulula ukuminyana. Ngaphandle kwesitoreji esikhulu, ukungena okuvuselelekayo ngale kwemikhawulo ethile kungaholela ekuncishisweni, ekuguquguqukeni kwentengo, kanye nezingozi zokwethenjelwa.

Ukuthuthukisa Ukuzinza Kwegridi Ngokuphendula Ngokushesha

Omunye wemisebenzi ebaluleke kakhulu yesistimu yokugcina amandla ebhethri esikalini esisetshenziswayo yikhono layo lokuphendula ngama-millisecond ekuphazamisekeni kwegridi. Amajeneretha endabuko angathatha imizuzwana noma amaminithi ukulungisa okukhiphayo, kodwa amasistimu ebhethri ajova noma amunce amandla cishe ngaso leso sikhathi. Le mpendulo esheshayo yenza isitoreji sebhethri esilinganisiwe silungele ukulawulwa kwamafrikhwensi okuyisisekelo, kusiza ukugcina ukuqina kwegridi njengoba okuvuselelekayo okuguquguqukayo kuthatha indawo yamajeneretha avumelanayo. Ukwengeza, lezi zinhlelo zinganikeza inertia yokwenziwa kanye nokusekelwa kwamandla asebenzayo, ezilingisa izici ezithile zezitshalo zamandla ezivamile. Kuma-opharetha egridi aphethe ukungena okuphezulu okuvuselelekayo, isistimu yokulondoloza amandla yebhethri yezinga eliphezulu esetshenziswa kahle isebenza njengesibambisi ukushaqeka, ishelele ukwehla okungazelelwe noma ukukhuphuka esizukulwaneni esivuselelekayo ngaphandle kokudubula iziqongo zamafutha ezinsalela.

Ukunika amandla Ukungena Okuvuselelekayo Okuphakeme Nokunciphisa Ukuncishiswa

Amapulazi elanga nawomoya ngokuvamile abhekana nokuncishiswa phakathi nezikhathi zokutholakala ngokweqile—ukumosha amandla ahlanzekile abengagcinwa ngenye indlela. Ngokumatanisa izitshalo ezivuselelekayo ne uhlelo lokugcina amandla ebhethri olusetshenziswayo, abanikazi bephrojekthi bangashintsha ukukhiqizwa kusuka kumanani aphansi noma amahora amanani angemahle kuya emahoreni adingeka kakhulu. Leli khono lokushintsha isikhathi lithuthukisa umnotho wephrojekthi ngenkathi kunciphisa amandla amoshayo. Ezingeni lesistimu, ukugcinwa kwebhethri kwesikali sokusetshenziswayo kuvumela ama-opharetha egridi ukuthi amukele umthamo ovuselelekayo ophakeme ngaphandle kokuthuthukisa izintambo zokudlulisela ngokushesha. Esikhundleni sokwakha izintambo ezintsha ezithatha iminyaka ukuze zivunyelwe, isitoreji singamunca ukugcwala kwasendaweni futhi siphume lapho umthamo wokudlulisela utholakala. Lokhu kwenza isitoreji sebhethri esisezingeni elisetshenziswayo sibe isinikezeli amandla esingabizi kakhulu sokuhlanganisa okuvuselelekayo, ikakhulukazi ezindaweni ezikude ezinomoya onamandla noma izinsiza zelanga kodwa uxhumo olubuthaka lwegridi.

Isinikezeli Esibalulekile Sokushintshwa Kwamandla Ahlanzekile

Ukusuka ekulawuleni imvamisa kuye ekushintsheni kwesikhathi okuvuselelekayo kanye nokuhlehliswa kokudlulisela, isitoreji sebhethri lesikali esisetshenziswayo sisuke kubuchwepheshe be-niche saya kugridi ebalulekile. Abathuthukisi bephrojekthi, izinsiza, nabakhiqizi bamandla abazimele abakwazi ukukwazi ukuziba lezi zinhlelo lapho behlela amaphothifoliyo avuselelekayo. Ngo Wenergy, siletha izixazululo ezididiyelwe ze-BESS zendawo yokuhlala, i-C&I, kanye nezinhlelo zokusebenza zesikali, ezisekelwa iminyaka engu-15 yebhethri ye-R&D namandla ochungechunge lokunikezela okugcwele kusuka kumaseli kuya kumasistimu. Izisombululo zethu ezifakazelwe ze-BESS ezineziqukathi zamaphrojekthi wegridi nezinsiza zenzelwe ukwethembeka, ukusekela ukushefa okuphezulu, ukulawulwa kwamafrikhwensi, kanye nokuhlanganiswa kwe-PV nesipiliyoni sokuthunyelwa komhlaba wangempela. Uma uhlola isistimu yokulondoloza amandla ebhethri esikalini sokusetshenziswa kwephrojekthi yakho elandelayo evuselelekayo evuselelekayo, sikumema ukuthi ucabangele i-Wenergy njengozakwethu oqonda kokubili izinselele zehadiwe kanye negridi ebaluleke kakhulu.
