Kuyini ukugcina amandla ebhethri?
Uhlelo lokugcina amandla ebhethri(BESS) iyisisombululo sobuchwepheshe esithuthukisiwe esivumela ukugcinwa kwamandla ngezindlela eziningi ukuze kusetshenziswe kamuva. Izinhlelo zokugcina amabhethri e-lithium ion, ikakhulukazi, zisebenzisa amabhethri ashajwayo ukugcina amandla akhiqizwa amaphaneli elanga noma anikezwa yigridi bese ewenza atholakale uma kudingeka. Izinzuzo zokugcina amandla ebhethri zifaka phakathi ukusebenza kahle kwamandla, ukonga, kanye nokusimama ngokuvumela imithombo evuselelekayo kanye nokunciphisa ukusetshenziswa. Njengoba ukushintshela kwamandla kude namafutha emvelo kuya emandleni avuselelekayo kuqoqa isivinini, izinhlelo zokugcina amabhethri ziba yisici esivame kakhulu empilweni yansuku zonke. Njengoba kunikezwe ukuguquguquka okuhilelekile emithonjeni yamandla njengomoya kanye nelanga, izinhlelo zamabhethri zibalulekile kumasevisi, amabhizinisi kanye nezindlu ukuze kutholakale ukunikezwa kwamandla okuqhubekayo. Izinhlelo zokugcina amandla aziseyona into ecatshangelwayo noma engeziwe. Ziyingxenye ebalulekile yezixazululo zamandla avuselelekayo.
Isebenza kanjani isistimu yokugcina ibhethri?
Isimiso sokusebenza se-uhlelo lokugcina amandla ebhethriilula. Amabhethri athola ugesi kusuka kugridi kagesi, ngqo esiteshini sikagesi, noma emthonjeni wamandla avuselelekayo njengamaphaneli elanga, bese ewugcina njengogesi ukuze awukhulule lapho kudingeka. Ohlelweni lwamandla elanga, amabhethri ayashaja emini futhi awukhiphe lapho ilanga lingakhanyi. Amabhethri esimanje esistimu yamandla elanga yasekhaya noma yebhizinisi ngokuvamile afaka i-inverter eyakhelwe ngaphakathi ukushintsha ugesi we-DC okhiqizwa amaphaneli elanga abe ugesi we-AC odingekayo ekunikezeni amandla izinto zikagesi noma imishini. Isitoreji sebhethri sisebenza nohlelo lokuphatha amandla oluphatha imijikelezo yokushaja nokukhipha ngokusekelwe ezidingweni zesikhathi sangempela kanye nokutholakala.
Yiziphi izinhlelo zokusebenza eziyinhloko zokugcina ibhethri?
Isitoreji sebhethri singasetshenziswa ngezindlela eziningi ezidlula isipele esiphuthumayo esilula uma kwenzeka ukuntuleka kwamandla noma ukucima kwamandla. Izinhlelo zokusebenza ziyahlukahluka kuye ngokuthi isitoreji sisetshenziselwa ibhizinisi noma ikhaya.
Kubasebenzisi bezentengiselwano kanye nezimboni, kunezinhlelo zokusebenza eziningana:
- Ukushefa okuphezulu, noma ikhono lokuphatha isidingo samandla ukuze kugwenywe ukwanda okungazelelwe kokusetshenziswa kwesikhathi esifushane
- Ukushintshanisa umthwalo, okuvumela amabhizinisi ukushintshanisa ukusetshenziswa kwamandla kusukela kwesinye isikhathi kuya kwesinye, ngokucindezela ibhethri lapho amandla ebiza kakhulu
- Ngokunikeza amakhasimende ithuba lokunciphisa isidingo segridi yesayithi lawo ngezikhathi ezibucayi - ngaphandle kokushintsha ukusetshenziswa kukagesi - ukugcina amandla kwenza kube lula kakhulu ukuhlanganyela ohlelweni lwe-Demand Response futhi wonge izindleko zamandla.
- Amabhethri ayisici esibalulekile sama-microgrid, adinga isitoreji samandla ukuze akwazi ukuphuma kugridi kagesi eyinhloko uma kudingeka.
- Ukuhlanganiswa okuvuselelwayo, njengoba amabhethri eqinisekisa ukuhamba kukagesi okubushelelezi nokuqhubekayo ngaphandle kokutholakala kwamandla avela emithonjeni evuselelekayo.
- Ukusebenzisa amandla avuselelekayo ngokwakho, njengoba abasebenzisi basemakhaya bangakhiqiza amandla elanga ngesikhathi sasemini bese besebenzisa izinto zabo zikagesi ekhaya ebusuku
- Ukusuka kugridi, noma ukuhlukana ngokuphelele nesikhungo sikagesi noma sikagesi
- Ukusekela ngokulondoloza okuphuthumayo uma kwenzeka ukucima kogesi
Yiziphi izinzuzo zokugcina amandla ebhethri?
Futhi ukugcina amabhethri kuvumela amabhizinisi ukuthi ahlanganyele ohlelweni lwe-Demand Response, ngaleyo ndlela adale imithombo emisha yemali engenayo.
Enye inzuzo ebalulekile yokugcina amabhethri ukuthi isiza amabhizinisi ukugwema ukuphazamiseka okubizayo okubangelwa ukucima kwegridi. Ukugcinwa kwamandla kuyinzuzo ehlelekile ngezikhathi zokwenyuka kwezindleko zamandla kanye nezinkinga zezwe nezepolitiki ezingathinta ukuphepha kokunikezwa kwamandla.
Isitoreji samandla ebhethri sihlala isikhathi esingakanani futhi singasibuyisela kanjani esimweni saso sesibili?
Iningi lezinhlelo zokugcina amabhethri amandla zihlala iminyaka emi-5 kuya kweyi-15. Njengengxenye yesistimu yezixazululo zokushintsha kwamandla, izitolo zamandla ebhethri zingamathuluzi okwenza kube nokusimama futhi, ngesikhathi esifanayo, zona ngokwazo kumele zisimame ngokugcwele.
Ukusetshenziswa kabusha kwamabhethri kanye nokusetshenziswa kabusha kwezinto eziqukethwe kuwo ekupheleni kwempilo yawo kuyimigomo yokuzinza kanye nokusetshenziswa okuphumelelayo koMnotho Ojikelezayo. Ukuthola inani elikhulayo lezinto ezivela ebhethrini le-lithium empilweni yesibili kuholela ezinzuzweni zemvelo, kokubili ezigabeni zokukhipha kanye nokulahla. Ukunikeza amabhethri impilo yesibili, ngokuwasebenzisa kabusha ngezindlela ezahlukene kodwa ezisasebenza kahle, nakho kuholela ezinzuzweni zomnotho.
Ubani ophethe uhlelo lokugcina amandla ebhethri?
Kungakhathaliseki ukuthi usuvele unesistimu yokugcina ibhethri esisebenzayo esakhiweni sakho noma unesifiso sokwengeza umthamo owengeziwe, i-LIAO ingasebenza nawe ukuqinisekisa ukuthi zonke izidingo zamandla zebhizinisi lakho ziyahlangatshezwa. Uhlelo lwethu lokugcina ibhethri lufakwe isofthiwe yethu yokwenza ngcono, eyenzelwe ukusebenza nazo zonke izinhlobo zezinsiza zamandla ezisatshalaliswayo futhi ingafakwa kalula ezinhlelweni ezikhona, njengezinhlelo ze-solar photovoltaic. I-LIAO izonakekela konke kusukela ekwakhiweni kuya ekuthuthukisweni nasekwakheni uhlelo lokugcina ibhethri, kanye nokusebenza kwalo okuvamile nokumangalisayo kanye nokugcinwa kwalo.
