Amacandelo amane angezantsi achaza ixabiso lokusebenza kolu lwakhiwo.

1. I-Micro-grid: Ukuguqula indawo yokutshaja ibe yiSiqithi samandla esizilinganiselayo

Inkqubo yokutshaja yokugcina umbane ngelanga, ngokwenkcazo, yi-DC micro-grid — inethiwekhi yamandla yasekuhlaleni enokulinganisela ukuveliswa kwayo, ukugcinwa kwayo, kunye nomthwalo wayo ngaphandle kokuthatha i-kilowatt enye kwisixhobo sombane, kunye ne-MIDA's.iinkqubo zokugcina amandla ebhetrikwayeizikhululo zokutshaja zeBESS ezidityanisiweyozenzelwe ngokukodwa ukusebenza kule ndlela. Kwi-island operating, i-PV array ngumthombo wamandla oyintloko, i-BESS yi-voltage kunye ne-frequency anchor, kwaye iitshaja ze-EV ziyimithwalo elawulekayo; xa ilanga linamandla kwaye ibhetri igcwele, indawo ithumela amandla angaphezulu, kwaye xa umthwalo unyuka, ibhetri iyawugubungela ngexesha langempela endaweni yoqhagamshelo lombane.

Iimfuneko zobunjineli bokuhlala kwisiqithi esikhuselekileyo azixoxiswananga kwaye ngoku zibhalwe phantsi. Phantsi kwe-IEC 61851-23:2023, nayiphi na inkqubo exhasa ukudluliselwa kwamandla okubhekisa kwicala elinye (i-BPT) kufuneka ihlangabezane neemfuno zenqanaba lesihlomelo zokhuseleko loqhagamshelo lwegridi, kubandakanya ukufunyanwa kokulwa nesiqithi okususa indawo kwigridi engasebenziyo ngaphakathi kwefestile yokufumanisa efunekayo, kunye nesixhobo sokujonga ukugquma esivavanyiweyo (i-IMD) esiqinisekisa rhoqo ukuhlukaniswa kwi-1000V+ DC. Yingakho ii-converter zokugcina eziqinisekisiweyo nezakhelwe injongo ethile - endaweni yeeyunithi ze-UPS ezilungisiweyo - ziyimfuneko kwiindawo zokutshaja ze-micro-grid.

Kwabaqhubi, amandla e-micro-grid aguqula iziseko zokutshaja ukusuka kwityala zibe yimpahla. Indawo enebhetri engama-200 kWh kunye ne-120 kW yokutshaja inokudlula kwingxaki yokungasebenzi kweenkonzo iiyure ezininzi, igcine iilori zokutshaja zihamba ngexesha lokuphendula kwimeko kaxakeka, kwaye ifanelekele izibonelelo kwiimarike ezihlawulela ii-micro-grid ezixhasa i-grid.

Uluhlu lwemveliso ye-MIDA lugubungela uluhlu olupheleleyo lwe-spectrum - ukusuka kwizikhululo zokuhlangula ezingama-65–200 kWh kunye neenkqubo zemodyuli ezingama-215 kWh ukuya kuthi ga kwiinkqubo zokutshaja zelanga ezingama-800–2,000 kWh - ngoko ke inqanaba lebhetri linokuthelekiswa ngokuchanekileyo ne-site throughput kunye nemida yoqhagamshelo lwegridi.

Isiphelo

Ukuhlanganiswa kokutshaja nge-solar-reservation akulona uphawu oluphezulu; lusisiseko sokusebenza sokutshaja nge-EV okunenzuzo, okuhambelanayo, nokuzinzileyo ngo-2026 nangaphezulu. Ngokudibanisa ukuvunwa kwe-PV okusebenzayo kakhulu, i-BESS buffering, kunye nokuguqulwa kwe-SiC okusekwe kwicala lesibini - kunye nonxibelelwano lwe-V2G olumiselweyo phantsi kwe-ISO 15118-20:2022 kunye nokhuseleko lwehadiwe olubhalwe phantsi kwe-IEC 61851-23:2023 - indawo edibeneyo ifumana imali kwimithombo emine yengeniso endaweni yeyodwa, iyasinda kwimicimbi yegridi endaweni yokuvala, kwaye inika ukuhamba okungekho kukhutshwa komoya ukusuka kumthombo ukuya kwivili. Uyilo lukhona namhlanje njengomgca wemveliso omnye, odityaniswe nomzi-mveliso: kwiinkqubo zokugcina amandla ebhetri kunye neemodyuli zamandla elanga ze-MPPT kwicala lokuvelisa, ngeemodyuli zamandla ze-AC-DC ezidityanisiweyo kunye nezisombululo zokutshaja ze-V2G kwicala lokuguqula, ukuya kwiinqwaba zokutshaja ze-ESS ezidityanisiweyo ze-60–400 kW kunye neenkqubo zokutshaja zelanga ezininzi-megawatt kwicala lokusasazwa. Abaqhubi abachaza iinkqubo ezidibeneyo, eziqinisekisiweyo, nezipheleleyo ngoku baza kusebenzisa izixhobo zokutshaja ezibiza kakhulu nezisebenza ngexesha eliphezulu kwigridi kwiminyaka elishumi ezayo.

I-MIDA Power — ityhala imida yokutshaja kwe-EV ngezisombululo zamandla zelanga ezidityanisiweyo, zokugcina, kunye nezamandla ezibhekisa kwicala ngalinye.
