Ukudala inkulumo ebanzi ngokuchazweuhlelo lokugcina amandla(ESS) idinga ukuhlolwa kwezingxenye ezihlukahlukene, okuhlanganisa ukucaciswa kwayo kobuchwepheshe, ukusebenza, izinzuzo, kanye nomxholo obanzi wokusetshenziswa kwayo. I-ESS eveziwe engu-100kW/215kWh, esebenzisa amandla amabhethri e-CATL e-lithium iron phosphate (LFP), imele ukuvela kwezinguquko ezibalulekile ezixazululweni zokugcina amandla, ukubhekelela izidingo zezimboni ezifana nokuphakelwa kwamandla aphuthumayo, ukuphathwa kwesidingo, nokuhlanganiswa kwamandla avuselelekayo. Lesi sihloko sivela ezigabeni ezimbalwa ukuze ihlanganise ingqikithi yesistimu, indima yayo ebalulekile ekuphathweni kwamandla kwesimanje, kanye nezisekelo zayo zobuchwepheshe.
Isingeniso Sezinhlelo Zokugcina Amandla
Amasistimu okugcina amandla abalulekile oguqukweni oluya ezindaweni ezisimeme futhi ezinokwethenjelwa zamandla. Banikeza indlela yokugcina amandla engeziwe akhiqizwa ngezikhathi zesidingo esiphansi (isigodi) futhi banikeze ngezikhathi zokufunwa okuphezulu (ukushefa okuphezulu), ngaleyo ndlela kuqinisekiswe ibhalansi phakathi kokunikezwa kwamandla kanye nesidingo. Leli khono aligcini nje ngokuthuthukisa ukusebenza kahle kwamandla kodwa futhi lidlala indima ebalulekile ekusimamiseni amagridi, ukuhlanganisa imithombo yamandla avuselelekayo, kanye nokuhlinzeka ngezixazululo zamandla eziphuthumayo.
I100kW/215kWh Energy Storage System
Ingqikithi yale ngxoxo ingu-100kW/215kWh ESS, isixazululo esisezingeni elimaphakathi esiklanyelwe izinhlelo zokusebenza zezimboni. Amandla ayo kanye nokukhishwa kwamandla kuyenza ibe yikhandidethi elifanele lamafekthri nezindawo zezimboni ezidinga amandla ayisipele athembekile kanye nokuphathwa okusebenzayo kwamandla okufunwa eceleni. Ukusetshenziswa kwamabhethri e-CATL lithium iron phosphate (LFP) kugcizelela ukuzibophezela ekusebenzeni kahle, ukuphepha, nokuphila isikhathi eside. Amabhethri e-LFP adume ngobuningi bawo bamandla aphezulu, okwenza izixazululo zokugcina ezihlangene nezisebenza kahle endaweni. Ngaphezu kwalokho, impilo yabo yomjikelezo omude iqinisekisa ukuthi isistimu ingasebenza iminyaka eminingi ngaphandle kokuwohloka okukhulu ekusebenzeni, kuyilapho iphrofayili yabo yokuphepha inciphisa izingozi ezihlobene nokubaleka okushisayo nomlilo.
Izingxenye Zesistimu Nokusebenza
I-ESS yakhiwe amasistimu angaphansi ambalwa abalulekile, ngalinye lidlala indima ehlukile ekusebenzeni kwalo:
Ibhethri Lesitoreji Samandla: Ingxenye eyinhloko lapho amandla agcinwa khona ngamakhemikhali. Ukukhethwa kwekhemistri ye-LFP kunikeza inhlanganisela yokuqina kwamandla, ukuphepha, nokuphila isikhathi eside okungenakuqhathaniswa nezinye izindlela eziningi.
Isistimu Yokulawula Ibhethri (BMS): Isistimu engaphansi ebalulekile eqapha futhi iphathe imingcele yokusebenza kwebhethri, iqinisekisa ukusebenza okuphelele nokuphila isikhathi eside.
Ukulawulwa Kwezinga Lokushisa: Uma kubhekwa ukuzwela kokusebenza kwebhethri nokuphepha kuzinga lokushisa, le sistimu engaphansi igcina indawo yokusebenza efanelekile yamabhethri.
Ukuvikelwa Komlilo: Izinyathelo zokuphepha zibaluleke kakhulu, ikakhulukazi kuzilungiselelo zezimboni. Lesi simiso esingaphansi sihlinzeka ngezindlela zokubona nokucindezela imililo, ukuqinisekisa ukuphepha kokufaka nendawo yakhona.
Ukukhanyisa: Iqinisekisa ukuthi uhlelo lusebenza kalula futhi lunakekeleke ngaphansi kwazo zonke izimo zokukhanyisa.
Ukusabalalisa Nokunakekela
Idizayini ye-ESS igcizelela ukusebenziseka kalula, ukuhamba, nokugcinwa kahle. Amandla ayo okufaka ngaphandle, akhuthazwe ukuklama kwayo okuqinile nezici zokuphepha ezibalulekile, ayenza ibe nezinto ezihlukahlukene ezilungiselelweni ezihlukahlukene zezimboni. Ukuhamba kwesistimu kuqinisekisa ukuthi ingathuthwa njengoba kudingekile, inikeze ukuguquguquka ekusebenzeni nasekuhleleni. Ukunakekela kwenziwa lula ukwakheka kwesistimu, okuvumela ukufinyelela kalula ezingxenyeni zokusevisa, ukushintshwa, noma ukuthuthukiswa.
Izicelo Nezinzuzo
I-100kW/215kWh ESS yenza izindima eziningi ngaphakathi komongo wemboni:
Ukunikezwa Kwamandla Ezimo Eziphuthumayo: Kusebenza njengesipele esibalulekile phakathi nokuphela kukagesi, siqinisekisa ukuqhubeka kokusebenza.
Ukunwetshwa Kwekhono Elinamandla: Idizayini yesistimu ivumela ukulinganisa, okuvumela izimboni ukuthi zandise umthamo wazo wokugcina amandla njengoba izidingo zikhula.
I-Peak Shaving kanye nokugcwalisa i-Valley: Ngokugcina amandla amaningi ngesikhathi sesidingo esiphansi futhi siwakhulule ngesikhathi sokufunwa okuphezulu, i-ESS isiza ekulawuleni izindleko zamandla nokunciphisa umthwalo kugridi.
Ukuzinzisa Umphumela We-Photovoltaics (PV): Ukuhlukahluka kokukhiqizwa kwamandla kagesi we-PV kungancishiswa ngokugcina amandla amaningi kanye nokuwasebenzisa ukuze bushelelezi amadiphu ekukhiqizeni.
Ukuqamba Okusha Kwezobuchwepheshe kanye Nomphumela Wemvelo
Ukwamukelwa kobuchwepheshe obuthuthukisiwe njengamabhethri e-LFP kanye nomklamo wohlelo oludidiyelwe kakhulu kubeka le-ESS njengesixazululo sokucabanga phambili. Lobu buchwepheshe abukhulisi nje kuphela ukusebenza kwesistimu kodwa futhi bunomthelela ekusimameni kwemvelo. Amandla okuhlanganisa ngempumelelo imithombo yamandla avuselelekayo anciphisa ukuthembela kumafutha ezinto ezimbiwa phansi futhi ehlise ukukhishwa kwekhabhoni. Ngaphezu kwalokho, impilo yomjikelezo omude wamabhethri e-LFP isho ukumosha okuncane kanye nomthelela wemvelo phezu kwempilo yohlelo.
Isiphetho
Isistimu yokugcina amandla engu-100kW/215kWh imele intuthuko enkulu ezisombululweni zokuphathwa kwamandla ezisetshenziswa ezimbonini. Ngokusebenzisa ubuchwepheshe bebhethri yesimanje kanye nokuhlanganisa amasistimu angaphansi abalulekile esixazululweni esihlangene nesiguquguqukayo, le ESS ibhekana nezidingo ezibalulekile zokuthembeka, ukusebenza kahle, nokusimama ekusebenziseni amandla. Ukuthunyelwa kwayo kungathuthukisa kakhulu ukuqina kokusebenza, kwehlise izindleko zamandla, futhi kube nomthelela ekusaseni lamandla elizinzile nelizinzile. Njengoba isidingo sokuhlanganisa okuvuselelekayo kanye nokuphathwa kwamandla siqhubeka sikhula, amasistimu afana nalawa azodlala indima ebaluleke kakhulu kumhlaba wamandla wakusasa.
