8月29日，全(quan)國首個智能柔性直流配電(dian)網(wang)示范工(gong)程(cheng)在浙江(jiang)杭(hang)州江(jiang)東(dong)新城(cheng)順利通過試運行考驗，經功能升級后(hou)正式(shi)投入運行。據悉，該工(gong)程(cheng)的建成實現了配電(dian)網(wang)從(cong)傳統(tong)放射型向多端互聯網(wang)絡轉(zhuan)變(bian)，可在百毫秒內快速隔離系(xi)統(tong)故障并恢復正常運行，大幅提升杭(hang)州電(dian)網(wang)的安全(quan)可靠性。
2016年，杭州供電公司為打(da)造可靠性高(gao)、互動友好、經濟高(gao)效的一流(liu)現(xian)代化配電網，率先啟動智能柔(rou)性直(zhi)流(liu)配電網技術研究(jiu)工(gong)作。2017年10月，智能柔(rou)性直(zhi)流(liu)配電網示范項目正式開(kai)工(gong)建設，工(gong)程額定電壓±10千(qian)伏，總換流(liu)容量3萬千(qian)瓦。
杭州(zhou)江東新城(cheng)智能(neng)柔性直(zhi)流配(pei)電(dian)(dian)(dian)網(wang)工(gong)程(cheng)通過采(cai)用(yong)區域(yu)協調控制(zhi)、故(gu)(gu)障(zhang)快速定(ding)位(wei)及隔離(li)保護等技術，實現(xian)多路電(dian)(dian)(dian)源同時為用(yong)戶供(gong)電(dian)(dian)(dian)，確保單(dan)路電(dian)(dian)(dian)源故(gu)(gu)障(zhang)情(qing)況下負(fu)荷安全經濟轉(zhuan)移。同時，該(gai)工(gong)程(cheng)可采(cai)用(yong)直(zhi)流供(gong)電(dian)(dian)(dian)模(mo)式，在不影響(xiang)電(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)能(neng)質量的情(qing)況下，為10千米外用(yong)戶提供(gong)供(gong)電(dian)(dian)(dian)服務，極大優化了(le)杭州(zhou)電(dian)(dian)(dian)網(wang)的供(gong)電(dian)(dian)(dian)能(neng)力。工(gong)程(cheng)還具備電(dian)(dian)(dian)動汽車充換(huan)電(dian)(dian)(dian)設施等多元(yuan)化負(fu)荷、儲能(neng)和分布(bu)式電(dian)(dian)(dian)源無障(zhang)礙接入的條件，助推能(neng)源互(hu)聯(lian)網(wang)發展。
