近日，國家發(fa)展改革委發(fa)布《關(guan)于進一步(bu)完善分(fen)時電價機(ji)制的通(tong)知》。《通(tong)知》部(bu)署各地進一步(bu)完善分(fen)時電價機(ji)制，服(fu)務以新能源為主(zhu)體的新型電力系統建設，促進能源綠色(se)低(di)碳發(fa)展。目(mu)前，全(quan)國已有(you)29個省份實施了分(fen)時電價機(ji)制。

業(ye)內人(ren)士(shi)指出，受此(ci)(ci)政(zheng)策引導，煤電將加快從(cong)基礎性電源(yuan)向(xiang)調節性兜底保(bao)供電源(yuan)轉型，此(ci)(ci)后電煤需求增長將得到(dao)有(you)效控制(zhi)，能夠(gou)為實現碳(tan)達(da)峰、碳(tan)中和目標作(zuo)出積極(ji)貢(gong)獻。

發展調(diao)峰(feng)電源和儲能是(shi)構建新型電力系(xi)統的基(ji)礎

近年來(lai)，我(wo)國(guo)能(neng)(neng)源消費結構快(kuai)速(su)變化。一方面，隨(sui)著我(wo)國(guo)產業結構的(de)不斷(duan)優化和(he)(he)人民(min)生活水平的(de)不斷(duan)提高，三產和(he)(he)居民(min)生活用電(dian)(dian)(dian)(dian)占比(bi)穩(wen)步(bu)提升，導致(zhi)我(wo)國(guo)用電(dian)(dian)(dian)(dian)峰(feng)(feng)(feng)谷(gu)差(cha)持續加大，全(quan)國(guo)日峰(feng)(feng)(feng)谷(gu)差(cha)比(bi)接(jie)近30%，部分(fen)大型城(cheng)市已經達到40%。另一方面，為(wei)實(shi)現碳達峰(feng)(feng)(feng)、碳中(zhong)和(he)(he)目標，風(feng)電(dian)(dian)(dian)(dian)、光(guang)伏(fu)發(fa)電(dian)(dian)(dian)(dian)裝機規模和(he)(he)占比(bi)快(kuai)速(su)提高。風(feng)電(dian)(dian)(dian)(dian)、光(guang)伏(fu)發(fa)電(dian)(dian)(dian)(dian)出(chu)(chu)力(li)不穩(wen)定，特(te)別是晚(wan)高峰(feng)(feng)(feng)時期光(guang)伏(fu)發(fa)電(dian)(dian)(dian)(dian)出(chu)(chu)力(li)為(wei)零(ling)。用電(dian)(dian)(dian)(dian)負(fu)荷(he)和(he)(he)發(fa)電(dian)(dian)(dian)(dian)出(chu)(chu)力(li)兩方面的(de)發(fa)展特(te)性，給電(dian)(dian)(dian)(dian)力(li)保供(gong)帶來(lai)了巨大挑戰。因此(ci)，必須(xu)大力(li)加強調峰(feng)(feng)(feng)儲(chu)能(neng)(neng)建設，在風(feng)電(dian)(dian)(dian)(dian)、光(guang)伏(fu)發(fa)電(dian)(dian)(dian)(dian)大發(fa)時能(neng)(neng)夠降低出(chu)(chu)力(li)乃至儲(chu)能(neng)(neng)，在風(feng)電(dian)(dian)(dian)(dian)、光(guang)伏(fu)發(fa)電(dian)(dian)(dian)(dian)出(chu)(chu)力(li)不足時能(neng)(neng)夠頂峰(feng)(feng)(feng)，才能(neng)(neng)保障清潔能(neng)(neng)源充分(fen)消納(na)，保障電(dian)(dian)(dian)(dian)力(li)供(gong)應安全(quan)穩(wen)定。
