3月27日從(cong)國家電(dian)(dian)網有限(xian)公司西(xi)北分部獲悉，3月25日西(xi)北電(dian)(dian)網新(xin)能源發電(dian)(dian)量(liang)達7.87億千瓦(wa)時(shi)，占當(dang)日全網發電(dian)(dian)量(liang)的32.39%、全網用電(dian)(dian)量(liang)的44.35%。其中，風電(dian)(dian)最大發電(dian)(dian)電(dian)(dian)力(li)3293萬(wan)千瓦(wa)、發電(dian)(dian)量(liang)6.21億千瓦(wa)時(shi)。西(xi)北電(dian)(dian)網這五項(xiang)新(xin)能源指標均(jun)創(chuang)新(xin)高。

據(ju)了解，本次(ci)新能(neng)源(yuan)日(ri)(ri)理論發電(dian)(dian)量達8.88億千瓦時(shi),晚高(gao)峰(feng)風電(dian)(dian)電(dian)(dian)力(li)最(zui)(zui)大達3293萬千瓦，均(jun)為歷(li)史單日(ri)(ri)最(zui)(zui)高(gao)水(shui)平(ping)。國網西北分(fen)部克服網內(nei)重要新能(neng)源(yuan)電(dian)(dian)力(li)送出通(tong)道檢修等問題的不利影響(xiang)，充(chong)分(fen)應用新能(neng)源(yuan)柔(rou)性調(diao)度(du)機制(zhi)，超前謀(mou)劃，多措并(bing)舉，提(ti)升(sheng)新能(neng)源(yuan)發電(dian)(dian)消納(na)水(shui)平(ping)。

根據(ju)預測，西北(bei)電網新能源日前理論(lun)發(fa)電量預測準確(que)率達99.4%，晚高峰風(feng)電電力預測準確(que)率97.4%，為電網運行方式安排提供(gong)依據(ju)。

國網(wang)(wang)西北分部通(tong)過大電(dian)(dian)網(wang)(wang)備(bei)(bei)用(yong)統籌，共(gong)安排火電(dian)(dian)機組停備(bei)(bei)及啟停調(diao)(diao)(diao)峰23臺(tai)次，容量834萬千瓦，將全(quan)網(wang)(wang)常規電(dian)(dian)源(yuan)負備(bei)(bei)用(yong)容量降(jiang)至(zhi)-1273萬千瓦，增(zeng)發新能源(yuan)電(dian)(dian)量9684萬千瓦時；與國家電(dian)(dian)網(wang)(wang)有(you)限公(gong)司國家電(dian)(dian)力調(diao)(diao)(diao)度控(kong)制(zhi)中心溝通(tong)，通(tong)過調(diao)(diao)(diao)整吉泉(quan)直流(liu)運行(xing)方(fang)式(shi)，減少(shao)對側(ce)電(dian)(dian)網(wang)(wang)運行(xing)方(fang)式(shi)對吉泉(quan)直流(liu)功率制(zhi)約60萬千瓦；應(ying)用(yong)智能協(xie)調(diao)(diao)(diao)控(kong)制(zhi)系統，自動協(xie)調(diao)(diao)(diao)各類電(dian)(dian)源(yuan)出力，750千伏沙魚線、拉官(guan)線檢修(xiu)期間網(wang)(wang)內重要斷面(mian)利用(yong)率達95%以(yi)上。

同時，國網西北分部(bu)密(mi)集(ji)開展各(ge)類交易、輔助服務共計(ji)46筆，增加(jia)新能(neng)源電量消納5837萬千瓦時。
