Ipulazi elingu-205MW Tranquility solar eFresno County, California, selisebenza kusukela ngo-2016. Ngo-2021, ipulazi lelanga lizohlonyiswa ngezinhlelo ezimbili zokugcina amandla ebhethri (BESS) enesilinganiso esiphelele sama-72 MW/288MWh ukusiza ukunciphisa ukuphehlwa kwamandla kagesi. izinkinga zezikhawu kanye nokwenza ngcono ukusebenza kahle kokukhiqizwa kwamandla epulazi lelanga.
Ukuthunyelwa kwesistimu yokugcina amandla ebhethri epulazini elisebenza ngelanga elisebenza ngelanga kudinga ukucatshangelwa kabusha kwendlela yokulawula yepulazi, ngoba ngenkathi kulawulwa futhi kusetshenziswa ipulazi lelanga, i-inverter yokushaja / ukukhipha uhlelo lokugcina amandla ebhethri kufanele futhi luhlanganiswe. Imingcele yayo ingaphansi kwemithetho eqinile ye-California Independent System Operator (CAISO) kanye nezivumelwano zokuthenga amandla.
Izidingo zesilawuli ziyinkimbinkimbi. Abalawuli bahlinzeka ngezinyathelo zokusebenza ezizimele nezihlanganisiwe kanye nokulawula impahla yokuphehla amandla. Izidingo zayo zihlanganisa:
Phatha izinsiza zamandla elanga nezinhlelo zokugcina ibhethri njengezimpahla zamandla ezihlukene zokudlulisa amandla kanye ne-California Independent System Operator (CAISO) kanye nezinjongo zokuhlela uma umuntu engasebenzi.
Ivimbela ukuphuma okuhlanganisiwe kwesikhungo samandla elanga kanye nesistimu yokugcina ibhethri ekudluleni umthamo wamandla axhunywe kwigridi futhi kungahle kulimaze ama-transformer esiteshini.
Lawula ukuncishiswa kwezikhungo zamandla elanga ukuze ukushaja amasistimu okugcina amandla kube yinto ehamba phambili ngaphezu kokusika amandla elanga.
Ukuhlanganiswa kwezinhlelo zokugcina amandla kanye nezinsimbi zikagesi zamapulazi elanga.
Ngokuvamile, ukulungiselelwa okunjalo kwesistimu kudinga izilawuli eziningi ezisuselwe kuhadiwe ezithembele kumayunithi wesikhumulo esikude ahlelwe ngawodwana (RTUs) noma Izilawuli Zengqondo Ezihlelekayo (PLCs). Ukuqinisekisa ukuthi uhlelo oluyinkimbinkimbi kangaka lwamayunithi ngamanye lusebenza kahle ngaso sonke isikhathi kuyinselele enkulu, edinga izinsiza ezibalulekile ukuze kuthuthukiswe futhi kuxazululwe izinkinga.
Ngokuphambene, ukulawula okuhlanganisiwe kube isilawuli esisekelwe kwisofthiwe esisodwa esilawula ngokumaphakathi yonke isayithi kuyisixazululo esinembe kakhudlwana, esikalayo, nesisebenza kahle. Yilokhu okukhethwa ngumnikazi wendawo yamandla elanga lapho efaka isilawuli sesizinda samandla avuselelekayo (PPC).
Isilawuli sesitshalo samandla elanga (i-PPC) singanikeza ukulawula okuvunyelanisiwe nokudidiyelwe. Lokhu kuqinisekisa ukuthi indawo yokuxhuma kanye nesiteshi ngasinye samanje namandla kagesi ahlangabezana nazo zonke izidingo zokusebenza futhi ahlale ngaphakathi kwemikhawulo yezobuchwepheshe yesistimu yamandla.
Enye indlela yokufeza lokhu ukulawula ngenkuthalo amandla okukhipha amandla elanga nezinhlelo zokugcina ibhethri ukuze kuqinisekiswe ukuthi amandla abo okukhiphayo angaphansi kwesilinganiso se-transformer. Iskena kusetshenziswa iluphu yokulawula impendulo engu-100-millisecond, isilawuli seplanti yamandla avuselelekayo (i-PPC) siphinde sithumele indawo yangempela yokusetha amandla kusistimu yokuphatha ibhethri (EMS) kanye nesistimu yokuphatha yesikhungo samandla elanga i-SCADA. Uma isistimu yesitoreji samandla ebhethri idingeka ukuthi ikhiphe, futhi ukukhipha kuzobangela inani elilinganiselwe le-transformer ukuba lidlule, isilawuli sinciphisa ukukhiqizwa kwamandla elanga futhi sikhiphe isistimu yokugcina amandla ebhethri; futhi ukukhishwa okuphelele kwesikhungo samandla elanga kungaphansi kwenani elilinganiselwe le-transformer.
Isilawuli senza izinqumo ezizimele ngokusekelwe kokubalulekile kwekhasimende kwebhizinisi, okungenye yezinzuzo ezimbalwa ezitholwa ngamakhono okuthuthukisa wesilawuli. Isilawuli sisebenzisa izibalo zokubikezela kanye nobuhlakani bokwenziwa ukuze senze izinqumo ngesikhathi sangempela ezisuselwe kuzintshisakalo ezingcono kakhulu zamakhasimende, ngaphakathi kwemithethonqubo nezivumelwano zokuthenga amandla, kunokuba sivalelwe iphethini yenkokhiso/yokukhipha ngesikhathi esithile sosuku.
Ilanga +ukugcinwa kwamandlaamaphrojekthi asebenzisa indlela yesofthiwe yokuxazulula izinkinga eziyinkimbinkimbi ezihlobene nokuphatha izinsiza zamandla elanga kanye nezinhlelo zokugcina ibhethri. Izixazululo ezisekelwe ku-Hardware esikhathini esidlule azikwazi ukufana nobuchwepheshe banamuhla obusizwa yi-AI obuhamba phambili ngesivinini, ukunemba, nokusebenza kahle. Izilawuli zezitshalo zamandla avuselelekayo ezisuselwa kusoftware (ama-PPC) zihlinzeka ngesixazululo esinokwethenjelwa, esinobufakazi besikhathi esizayo esilungiselelwa ubunzima okwethulwa yimakethe yamandla yekhulu lama-21.
