智(zhi)能微網(wang)電站存在兩種典(dian)型的運行模式

1是(shi)正常情況下(xia)微電網(wang)與常規配電網(wang)并網(wang)運(yun)行，稱為并機(ji)模(mo)式;

2是(shi)當檢測(ce)到(dao)電(dian)(dian)網(wang)故障或電(dian)(dian)能質量不滿足要求(qiu)時，微電(dian)(dian)網(wang)將及時與電(dian)(dian)網(wang)斷開(kai)而單獨運行(xing)，稱為單機運行(xing)模式(shi)。

離網運(yun)行也稱孤(gu)島運(yun)行，是指在(zai)電(dian)網故(gu)障(zhang)或計劃需(xu)要時，與主網配電(dian)系(xi)統斷開，由DG、儲能裝(zhuang)置和負荷(he)構成的運(yun)行方式。
