一(yi)、光伏儲能系統(tong)

   目前，電網(wang)(wang)公司通(tong)常要(yao)求光伏并(bing)網(wang)(wang)系(xi)統(tong)(tong)(tong)為不(bu)可逆(ni)(ni)(ni)流(liu)發(fa)(fa)電系(xi)統(tong)(tong)(tong)，即光伏并(bing)網(wang)(wang)系(xi)統(tong)(tong)(tong)所發(fa)(fa)的(de)電由(you)本地負(fu)荷(he)消(xiao)耗，多余(yu)的(de)電不(bu)允許通(tong)過低壓配電變(bian)壓器向(xiang)上級電網(wang)(wang)逆(ni)(ni)(ni)向(xiang)送電。在(zai)并(bing)網(wang)(wang)發(fa)(fa)電系(xi)統(tong)(tong)(tong)中，由(you)于外部環境是不(bu)斷(duan)變(bian)化的(de)，為了防止光伏并(bing)網(wang)(wang)系(xi)統(tong)(tong)(tong)逆(ni)(ni)(ni)向(xiang)發(fa)(fa)電，系(xi)統(tong)(tong)(tong)需要(yao)進行(xing)逆(ni)(ni)(ni)流(liu)檢(jian)測，通(tong)過實時監測配電變(bian)壓器低壓出口側的(de)電壓、電流(liu)信(xin)號來調節(jie)系(xi)統(tong)(tong)(tong)的(de)發(fa)(fa)電功(gong)率，從(cong)而達(da)到光伏并(bing)網(wang)(wang)系(xi)統(tong)(tong)(tong)的(de)防逆(ni)(ni)(ni)流(liu)功(gong)能。

   光(guang)伏(fu)儲(chu)能(neng)系統主要(yao)由電(dian)(dian)(dian)網、光(guang)伏(fu)、儲(chu)能(neng)、用(yong)(yong)電(dian)(dian)(dian)設備、表計、監控系統組(zu)成。利用(yong)(yong)光(guang)伏(fu)發(fa)電(dian)(dian)(dian)、低谷(gu)電(dian)(dian)(dian)網電(dian)(dian)(dian)價實現電(dian)(dian)(dian)量的(de)存儲(chu)，并在用(yong)(yong)電(dian)(dian)(dian)高(gao)峰(feng)和電(dian)(dian)(dian)價高(gao)時將(jiang)存儲(chu)在儲(chu)能(neng)系統的(de)電(dian)(dian)(dian)量用(yong)(yong)出(chu)去。同時也可以作為備用(yong)(yong)電(dian)(dian)(dian)源(yuan)，以備市電(dian)(dian)(dian)出(chu)現故障情(qing)況。
