電老虎網資訊：江(jiang)蘇(su)蘇(su)州西(xi)分(fen)區電(dian)(dian)網(wang)成功實施今年首次(ci)電(dian)(dian)力(li)需(xu)求響(xiang)應(ying)(ying)，實際響(xiang)應(ying)(ying)負(fu)荷(he)為2.6萬千瓦(wa)，有效(xiao)緩解了該分(fen)區的(de)(de)電(dian)(dian)力(li)供應(ying)(ying)緊張狀(zhuang)況。這是(shi)國(guo)網(wang)江(jiang)蘇(su)省電(dian)(dian)力(li)公司首次(ci)按照電(dian)(dian)網(wang)分(fen)區實施電(dian)(dian)力(li)需(xu)求響(xiang)應(ying)(ying)，實現了需(xu)求響(xiang)應(ying)(ying)資源(yuan)在分(fen)區電(dian)(dian)網(wang)的(de)(de)精準調度，標志(zhi)著國(guo)網(wang)江(jiang)蘇(su)電(dian)(dian)力(li)需(xu)求響(xiang)應(ying)(ying)進入實際應(ying)(ying)用(yong)的(de)(de)新階段。

電(dian)(dian)(dian)(dian)(dian)力需求響(xiang)(xiang)(xiang)應(ying)是電(dian)(dian)(dian)(dian)(dian)力客(ke)戶(hu)根據電(dian)(dian)(dian)(dian)(dian)力市(shi)場價格信號或激勵措施(shi)，改變(bian)其用電(dian)(dian)(dian)(dian)(dian)行為，減少或增加用電(dian)(dian)(dian)(dian)(dian)，進(jin)而促(cu)進(jin)電(dian)(dian)(dian)(dian)(dian)力供(gong)需平(ping)衡、保(bao)障(zhang)系(xi)統穩定運行的(de)行為。與(yu)電(dian)(dian)(dian)(dian)(dian)力供(gong)求矛盾突出時實施(shi)政府(fu)批準(zhun)的(de)有序用電(dian)(dian)(dian)(dian)(dian)方案、限制(zhi)客(ke)戶(hu)用電(dian)(dian)(dian)(dian)(dian)這一(yi)行政手段(duan)(duan)不同，電(dian)(dian)(dian)(dian)(dian)力需求響(xiang)(xiang)(xiang)應(ying)屬市(shi)場手段(duan)(duan)，由滿足一(yi)定條(tiao)件(jian)的(de)電(dian)(dian)(dian)(dian)(dian)力客(ke)戶(hu)自(zi)愿申(shen)請參加。2015年(nian)，在江蘇(su)省經信委(wei)指導(dao)下，國網江蘇(su)電(dian)(dian)(dian)(dian)(dian)力在全(quan)國率(lv)先試(shi)點實施(shi)電(dian)(dian)(dian)(dian)(dian)力需求響(xiang)(xiang)(xiang)應(ying)；2016年(nian)單(dan)次需求響(xiang)(xiang)(xiang)應(ying)負荷(he)量最大達352萬千瓦，居世(shi)界(jie)第一(yi)，并首次有居民客(ke)戶(hu)參與(yu)。電(dian)(dian)(dian)(dian)(dian)力需求響(xiang)(xiang)(xiang)應(ying)的(de)成(cheng)功實施(shi)，實現了江蘇(su)負荷(he)管理從行政性的(de)有序用電(dian)(dian)(dian)(dian)(dian)手段(duan)(duan)向(xiang)市(shi)場化的(de)需求響(xiang)(xiang)(xiang)應(ying)轉變(bian)，但當時均為試(shi)驗(yan)，以驗(yan)證(zheng)其可行性和響(xiang)(xiang)(xiang)應(ying)能力。

為(wei)推進電(dian)(dian)(dian)力(li)(li)需(xu)求(qiu)響(xiang)(xiang)應(ying)實(shi)用化，今年(nian)年(nian)初，國網(wang)江蘇電(dian)(dian)(dian)力(li)(li)與(yu)江蘇省(sheng)經信委協商，將其作為(wei)有序(xu)用電(dian)(dian)(dian)的(de)前置(zhi)手(shou)(shou)段，納入(ru)有序(xu)用電(dian)(dian)(dian)方案(an)，即在電(dian)(dian)(dian)力(li)(li)供應(ying)緊張時，優先啟動需(xu)求(qiu)響(xiang)(xiang)應(ying)，如還有缺口再(zai)實(shi)施傳統(tong)的(de)有序(xu)用電(dian)(dian)(dian)手(shou)(shou)段。同時，國網(wang)江蘇電(dian)(dian)(dian)力(li)(li)進一(yi)步加強需(xu)求(qiu)響(xiang)(xiang)應(ying)精(jing)細化管理(li)，建(jian)立了分(fen)級分(fen)區(qu)管理(li)機制，全省(sheng)28個(ge)電(dian)(dian)(dian)網(wang)分(fen)區(qu)內客(ke)戶(hu)的(de)需(xu)求(qiu)響(xiang)(xiang)應(ying)負(fu)荷資源與(yu)所在分(fen)區(qu)相匹配，并將需(xu)求(qiu)響(xiang)(xiang)應(ying)精(jing)確控制到(dao)客(ke)戶(hu)確認(ren)可以(yi)參與(yu)響(xiang)(xiang)應(ying)的(de)每一(yi)臺設備(bei)，實(shi)現了需(xu)求(qiu)響(xiang)(xiang)應(ying)資源在分(fen)區(qu)電(dian)(dian)(dian)網(wang)的(de)精(jing)準(zhun)調度。

進入7月以來，江蘇地區氣溫不斷攀升，用電負荷增長迅速，蘇州市最高用電負荷已突破2300萬千瓦，創歷史新高。7月11日10時許，蘇州市調根據氣溫變化和用電情況，預測13時30分至14時30分蘇州西分區電網將出現電力供應緊張局面，便向蘇州供電公司營銷部通報。由蘇州供電公司營銷部按照國網江蘇電力既定方案，在該分區電網啟動電力需求響應，向4個負荷集成商邀約，涉及客戶20家，其中工業客戶8戶、非工業客戶12戶，實際響應負荷2.6萬千瓦，有效保障了蘇州西分區電網安全穩定運行。據悉，如采用傳統的有序用電行政手段，將影響蘇州市新區、相城等中心區域內61家客戶的正常用電。而本次需求響應不僅涉及客戶數少了2/3，而且涉及客戶均為自愿參與，未造成任何不良社會影響。
