Izigaba ezine ezingezansi zichaza inani lokusebenza kwalolu lwakhiwo.

1. Igridi Encane: Ukuguqula Indawo Yokushaja Ibe Yisiqhingi Samandla Esizilinganiselayo

Uhlelo lokushaja isitoreji selanga, ngokwencazelo, luyi-DC micro-grid — inethiwekhi yamandla yendawo engakwazi ukulinganisela ukukhiqizwa kwayo, isitoreji, kanye nomthwalo ngaphandle kokudonsa i-kilowatt eyodwa kusuka ku-utility, kanye ne-MIDA's.izinhlelo zokugcina amandla ebhethrifuthiiziteshi zokushaja ze-BESS ezihlanganisiwezenzelwe ngqo ukusebenza kule modi. Ekusebenzeni kwesiqhingi, i-PV array ingumthombo wamandla oyinhloko, i-BESS iyi-voltage kanye ne-frequency anchor, kanti amashaja e-EV ayimithwalo elawulwayo; lapho ilanga linamandla futhi ibhethri ligcwele, indawo ithumela amandla asele, futhi lapho umthwalo ukhuphuka, ibhethri liyawumboza ngesikhathi sangempela kunokuxhumeka kosizo.

Izidingo zobunjiniyela zokwakhiwa kwesiqhingi esiphephile azixoxiswani futhi manje sezibhaliwe. Ngaphansi kwe-IEC 61851-23:2023, noma yiluphi uhlelo olusekela ukudluliselwa kwamandla okuqondiswayo (i-BPT) kumele luhlangabezane nezidingo zezinga lesithasiselo zokuphepha kokuxhumeka kwegridi, okuhlanganisa ukutholwa kokulwa nesiqhingi okuhlukanisa indawo kusuka kugridi engasebenzi kahle ngaphakathi kwefasitela lokutholwa elidingekayo, kanye nedivayisi yokuqapha ukufudumeza ehlolwe ngokwayo (i-IMD) eqinisekisa njalo ukuhlukaniswa ku-1000V+ DC. Yingakho abaguquli besitoreji abaqinisekisiwe, abakhelwe ngenhloso - esikhundleni samayunithi e-UPS aguquliwe - beyimpoqo ezindaweni zokushaja zegridi encane.

Kwabasebenzi, ikhono le-micro-grid liguqula ingqalasizinda yokushaja kusuka esikweletini ibe yimpahla. Indawo enebhethri engu-200 kWh kanye ne-120 kW yokushaja ingadlula ekungasebenzi kahle kwezinsizakusebenza amahora amaningi, igcine amaloli okushaja ehamba ngesikhathi sokuphendula okuphuthumayo, futhi ifanelekele izikhuthazo ezimakethe ezikhokhela ama-micro-grid asekela i-grid.

Isiphetho

Ukuhlanganiswa kokushaja kwesitoreji selanga akuyona into esezingeni eliphezulu; kuyisisekelo sokusebenza sokushaja kwe-EV okunenzuzo, okuhambisanayo, nokuqinile ngo-2026 nangale kwalokho. Ngokuhlanganisa ukuvunwa kwe-PV okusebenzayo kakhulu, ukubhafa kwe-BESS, kanye nokuguqulwa kwe-SiC okusekelwe ku-bidirectional — ngokuxhumana kwe-V2G okujwayelekile ngaphansi kwe-ISO 15118-20:2022 kanye nokuphepha kwehadiwe okubhalwe ngaphansi kwe-IEC 61851-23:2023 — indawo ehlanganisiwe ithola imali engenayo emine esikhundleni somunye, isinda emicimbini yegridi esikhundleni sokuvala, futhi iletha ukuhamba kwe-zero-emission kusuka emthonjeni kuya esiteringini. Ukwakhiwa kukhona namuhla njengomugqa womkhiqizo owodwa, ohlanganiswe efektri: kusukela ezinhlelweni zokugcina amandla ebhethri kanye namamojula wamandla elanga e-MPPT ohlangothini lokukhiqiza, ngokusebenzisa amamojula wamandla e-AC-DC akabili kanye nezixazululo zokushaja ze-V2G ohlangothini lokuguqula, kuya kuma-piles okushaja e-ESS ahlanganisiwe angu-60-400 kW kanye nezinhlelo zokushaja zelanga eziningi-megawatt ohlangothini lokufakwa. Abasebenzi abachaza izinhlelo ezihlanganisiwe, eziqinisekisiwe, eziphelele ngezindinganiso manje bazobe besebenzisa izimpahla zokushaja ezibiza kakhulu nezisebenza isikhathi eside kakhulu kugridi eminyakeni eyishumi ezayo.

I-MIDA Power — idlula imikhawulo yokushaja kwe-EV ngezixazululo zamandla zelanga ezihlanganisiwe, isitoreji, kanye nezixazululo zamandla eziqondiswe kabili.
