根據青海省能源局數據，截至2020年10月底，青海全省新能源裝機占比達到57.2%，海南、海西兩個千萬千瓦級可再生能源基地的可再生能源裝機規模分別達到1543.6萬千瓦、1012萬千瓦。“十四五”期間，青海省將再建兩個千萬千瓦級可再生能源基地，構建多能互補、集成優化的清潔能源體系，打造“綠電特區”。

此前，在2019年6月9日(ri)0時至(zhi)23日(ri)24時，青(qing)海(hai)(hai)省(sheng)成功實現了“綠(lv)電(dian)(dian)(dian)15日(ri)”。根據國網青(qing)海(hai)(hai)省(sheng)電(dian)(dian)(dian)力公(gong)司調控中心統(tong)計(ji)數據顯(xian)示，“綠(lv)電(dian)(dian)(dian)15日(ri)”期間(jian)，青(qing)海(hai)(hai)電(dian)(dian)(dian)網最大用電(dian)(dian)(dian)負荷847萬千瓦(wa)(wa)(wa)，全(quan)省(sheng)用電(dian)(dian)(dian)量(liang)28.39億(yi)千瓦(wa)(wa)(wa)時。累(lei)計(ji)發(fa)電(dian)(dian)(dian)量(liang)39.78億(yi)千瓦(wa)(wa)(wa)時，其中水電(dian)(dian)(dian)發(fa)電(dian)(dian)(dian)量(liang)占比73.5%、光伏占比16%、風電(dian)(dian)(dian)占比8.6%、火電(dian)(dian)(dian)占比1.8%。新能源發(fa)電(dian)(dian)(dian)量(liang)占全(quan)部用電(dian)(dian)(dian)量(liang)的34.7%。

國家電(dian)網有限(xian)公司總工程師(shi)陳國平在《現(xian)代電(dian)力(li)(li)(li)(li)系統(tong)(tong)的(de)問題、挑戰(zhan)與發展方向》報告中指出(chu)：新(xin)(xin)能源(yuan)(yuan)波動大(da)、我國靈活調(diao)節電(dian)源(yuan)(yuan)占比低，電(dian)力(li)(li)(li)(li)系統(tong)(tong)調(diao)節能力(li)(li)(li)(li)嚴重不(bu)(bu)足；直流、新(xin)(xin)能源(yuan)(yuan)缺乏常規電(dian)源(yuan)(yuan)的(de)慣量(liang)、調(diao)頻(pin)、調(diao)壓等功能，導致系統(tong)(tong)調(diao)頻(pin)調(diao)壓能力(li)(li)(li)(li)持續(xu)下降；新(xin)(xin)能源(yuan)(yuan)出(chu)力(li)(li)(li)(li)不(bu)(bu)確定(ding)性(xing)強，電(dian)力(li)(li)(li)(li)供應保障難(nan)度不(bu)(bu)斷增加(jia)。現(xian)代電(dian)力(li)(li)(li)(li)系統(tong)(tong)自身發展重構需要圍(wei)繞解(jie)決3個關鍵問題：系統(tong)(tong)慣量(liang)、調(diao)節能力(li)(li)(li)(li)、支撐能力(li)(li)(li)(li)。他提出(chu)，在電(dian)源(yuan)(yuan)支撐方面，大(da)力(li)(li)(li)(li)發展具有傳統(tong)(tong)同步電(dian)源(yuan)(yuan)特性(xing)的(de)光熱電(dian)源(yuan)(yuan)。

目(mu)前，青海(hai)省共有4座太陽能(neng)(neng)光熱(re)(re)電站(zhan)(zhan)，分別為：中(zhong)(zhong)廣(guang)核德(de)令(ling)哈(ha)5萬千(qian)瓦導熱(re)(re)油槽式(shi)電站(zhan)(zhan)（儲(chu)能(neng)(neng)時(shi)長9小(xiao)時(shi)）、青海(hai)中(zhong)(zhong)控德(de)令(ling)哈(ha)5萬千(qian)瓦熔(rong)鹽(yan)(yan)塔(ta)式(shi)電站(zhan)(zhan)（儲(chu)能(neng)(neng)時(shi)長7小(xiao)時(shi)）、中(zhong)(zhong)電建青海(hai)共和5萬千(qian)瓦熔(rong)鹽(yan)(yan)塔(ta)式(shi)電站(zhan)(zhan)（儲(chu)能(neng)(neng)時(shi)長6小(xiao)時(shi)），以及(ji)魯能(neng)(neng)海(hai)西州多能(neng)(neng)互補集成(cheng)優化國家示(shi)范工(gong)程5萬千(qian)瓦熔(rong)鹽(yan)(yan)塔(ta)式(shi)電站(zhan)(zhan)（配置12小(xiao)時(shi)熔(rong)鹽(yan)(yan)儲(chu)熱(re)(re)系統）。

根據清(qing)華大學(xue)能源(yuan)(yuan)互聯網(wang)研究院(yuan)的(de)(de)最新研究結果(guo)，如(ru)果(guo)安(an)裝22GW光伏(fu)和7GW風電，青海電網(wang)在(zai)豐水期可(ke)(ke)連續3日全(quan)清(qing)潔能源(yuan)(yuan)供電（包(bao)括省內負荷(he)以及(ji)特(te)高壓(ya)外送河南）；如(ru)果(guo)在(zai)此基礎上配置(zhi)4GW太(tai)陽能熱發電，青海省在(zai)豐水期可(ke)(ke)高達創世界紀錄(lu)的(de)(de)連續30日全(quan)清(qing)潔能源(yuan)(yuan)供電。在(zai)青海省打造“綠電特(te)區”中，太(tai)陽能光熱將具有不可(ke)(ke)或缺(que)的(de)(de)地位(wei)。

光熱發電(dian)具(ju)有傳統同步發電(dian)機組并網特性，同時兼具(ju)功(gong)率調節和(he)電(dian)壓支撐作(zuo)用，可以替代(dai)“儲能(neng)(neng)+調相機”的配置(zhi)方案，從而實現新(xin)能(neng)(neng)源(yuan)發電(dian)的可控可調。中(zhong)國電(dian)科(ke)院專家(jia)這樣(yang)表(biao)示(shi)。

在(zai)我國，由于處于示(shi)范(fan)階段，太(tai)(tai)陽(yang)能(neng)熱發(fa)電(dian)(dian)的(de)(de)(de)度電(dian)(dian)成本相(xiang)對較高。然而(er)，在(zai)迪拜，950MW太(tai)(tai)陽(yang)能(neng)光(guang)(guang)熱光(guang)(guang)伏(fu)混合(he)電(dian)(dian)站項(xiang)(xiang)(xiang)目購電(dian)(dian)協(xie)議價低至(zhi)7.3美(mei)分/kWh（購電(dian)(dian)協(xie)議期長達35年）,該項(xiang)(xiang)(xiang)目開(kai)創了全(quan)球太(tai)(tai)陽(yang)能(neng)光(guang)(guang)熱跨能(neng)源(yuan)(yuan)混合(he)發(fa)電(dian)(dian)模式(shi)(shi)。德國航(hang)空航(hang)天(tian)中心（DLR）研究提出(chu)，在(zai)現有條件(jian)下(xia)，光(guang)(guang)熱與光(guang)(guang)伏(fu)相(xiang)結合(he)是目前最具(ju)前景(jing)的(de)(de)(de)太(tai)(tai)陽(yang)能(neng)發(fa)電(dian)(dian)技術路線。在(zai)國家能(neng)源(yuan)(yuan)局(ju)綜(zong)合(he)司發(fa)布(bu)的(de)(de)(de)《關于2021年風(feng)電(dian)(dian)、光(guang)(guang)伏(fu)發(fa)電(dian)(dian)開(kai)發(fa)建設有關事項(xiang)(xiang)(xiang)的(de)(de)(de)通知(征求意見稿)》中也提出(chu)，鼓(gu)勵新(xin)能(neng)源(yuan)(yuan)企業創新(xin)發(fa)展(zhan)模式(shi)(shi)，推進“光(guang)(guang)伏(fu)+光(guang)(guang)熱”等(deng)示(shi)范(fan)工程，進一步(bu)探索新(xin)模式(shi)(shi)新(xin)業態(tai)。

上海電(dian)(dian)(dian)(dian)(dian)(dian)氣電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)集團韓強撰(zhuan)文(wen)指出：太(tai)陽(yang)能(neng)光(guang)(guang)(guang)熱電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)具有光(guang)(guang)(guang)電(dian)(dian)(dian)(dian)(dian)(dian)轉化率高、儲能(neng)效率高、發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)連續穩定(ding)、調峰(feng)能(neng)力(li)(li)強等多種優勢(shi)(shi)。由于其內在(zai)的(de)靈活(huo)性及長(chang)時(shi)(shi)間儲熱能(neng)力(li)(li)，可(ke)以與(yu)間歇性可(ke)再生能(neng)源發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)技(ji)術(shu)以及其他(ta)熱力(li)(li)發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)技(ji)術(shu)結合(he)使用。相對獨立(li)的(de)光(guang)(guang)(guang)熱電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)，光(guang)(guang)(guang)熱混(hun)合(he)型電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)能(neng)夠降低均化電(dian)(dian)(dian)(dian)(dian)(dian)力(li)(li)成本。在(zai)白天陽(yang)光(guang)(guang)(guang)好時(shi)(shi)，光(guang)(guang)(guang)伏(fu)(fu)電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)直(zhi)接向電(dian)(dian)(dian)(dian)(dian)(dian)網供電(dian)(dian)(dian)(dian)(dian)(dian)；在(zai)用電(dian)(dian)(dian)(dian)(dian)(dian)高峰(feng)期，比如夜間，光(guang)(guang)(guang)熱將通(tong)過(guo)長(chang)時(shi)(shi)間、安全環保的(de)儲熱裝置發(fa)(fa)揮其優勢(shi)(shi)。光(guang)(guang)(guang)熱電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)可(ke)以看作一個儲能(neng)電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)，作為(wei)(wei)光(guang)(guang)(guang)伏(fu)(fu)等可(ke)靠(kao)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)力(li)(li)配套儲能(neng)電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)，通(tong)過(guo)光(guang)(guang)(guang)熱電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)優越(yue)的(de)調節(jie)性能(neng)，可(ke)以使電(dian)(dian)(dian)(dian)(dian)(dian)力(li)(li)系統(tong)接納光(guang)(guang)(guang)伏(fu)(fu)等多種能(neng)源發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)形式的(de)能(neng)力(li)(li)大大提升。光(guang)(guang)(guang)熱混(hun)合(he)型電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)將作為(wei)(wei)一種最具前景的(de)太(tai)陽(yang)能(neng)發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)技(ji)術(shu)趨勢(shi)(shi)推動太(tai)陽(yang)能(neng)新興市場的(de)快速發(fa)(fa)展。
