  隨著(zhu)新(xin)(xin)能(neng)(neng)(neng)源大規模并網和(he)新(xin)(xin)型(xing)用(yong)能(neng)(neng)(neng)設備(bei)廣(guang)泛接入,新(xin)(xin)型(xing)電(dian)力系統“雙(shuang)(shuang)高(gao)”“雙(shuang)(shuang)低”“雙(shuang)(shuang)波動”特征(zheng)日趨明顯,大規模新(xin)(xin)能(neng)(neng)(neng)源發電(dian)將(jiang)對持(chi)續可靠供電(dian)、電(dian)網安全穩定和(he)用(yong)電(dian)成本控制等造成沖擊(ji)。電(dian)氫(qing)融合能(neng)(neng)(neng)夠(gou)有機結合電(dian)能(neng)(neng)(neng)與氫(qing)能(neng)(neng)(neng)優勢特性,推動多能(neng)(neng)(neng)源互聯互濟與源網荷(he)儲(chu)深度協(xie)同,是“雙(shuang)(shuang)碳”目標下新(xin)(xin)型(xing)電(dian)力系統構(gou)建的重要載體。

  電氫融合發展價值判斷

  一是電氫融合可全(quan)面提升電力系統全(quan)時間(jian)尺度靈活調節能力,支(zhi)撐新能源大規模安全(quan)穩(wen)定消(xiao)納。

  短時間尺度(du)看,電(dian)氫(qing)(qing)融(rong)合響應速(su)(su)度(du)快,可(ke)(ke)快速(su)(su)平抑新能源出(chu)力波動。電(dian)制氫(qing)(qing)環節,以堿性(xing)電(dian)解水技術(shu)路線(xian)為例,其功(gong)率(lv)爬坡速(su)(su)度(du)可(ke)(ke)達到每秒25%額定(ding)功(gong)率(lv),調(diao)(diao)節范圍(wei)為30%~120%,是較理想的可(ke)(ke)調(diao)(diao)柔性(xing)負荷。氫(qing)(qing)發電(dian)環節,氫(qing)(qing)燃(ran)料電(dian)池響應速(su)(su)度(du)為毫秒至秒級(ji),氫(qing)(qing)燃(ran)氣輪機響應速(su)(su)度(du)為分鐘(zhong)至小時級(ji),調(diao)(diao)節性(xing)能優(you)越,可(ke)(ke)全面參(can)與(yu)調(diao)(diao)頻(pin)、抑制短時功(gong)率(lv)波動、日(ri)內(nei)調(diao)(diao)峰等(deng)。

  長(chang)時間尺度看,氫(qing)以氣、液、固等(deng)物質形(xing)態長(chang)期(qi)存儲(chu)(chu)(chu),可滿足新能(neng)(neng)源跨(kua)周、跨(kua)季(ji)等(deng)長(chang)周期(qi)調(diao)節需求。與傳(chuan)統儲(chu)(chu)(chu)能(neng)(neng)技術相比,除了(le)轉換(huan)效率偏(pian)低,氫(qing)儲(chu)(chu)(chu)能(neng)(neng)在(zai)功(gong)率容(rong)量(liang)(liang)和儲(chu)(chu)(chu)能(neng)(neng)周期(qi)等(deng)方面(mian)均具有顯(xian)著優(you)勢(shi)(shi)。由于儲(chu)(chu)(chu)氫(qing)容(rong)量(liang)(liang)投資相對(dui)較小,在(zai)跨(kua)季(ji)節調(diao)峰、應急備(bei)用等(deng)充放電(dian)循環(huan)次數較少、儲(chu)(chu)(chu)能(neng)(neng)時長(chang)較長(chang)的(de)場景下,氫(qing)儲(chu)(chu)(chu)能(neng)(neng)具有明顯(xian)的(de)成(cheng)本(ben)優(you)勢(shi)(shi)。

  二是(shi)電氫(qing)融合(he)可推動電網與氫(qing)網靈(ling)活互濟(ji),促進更大范圍能源優(you)化(hua)配置,提升電力系統(tong)運行效率(lv)及本(ben)質安全水(shui)平。

  時間維度上,通(tong)過儲氫平(ping)(ping)抑電源(yuan)(yuan)(yuan)、負(fu)荷波動,提高(gao)發(fa)(fa)輸變(bian)(bian)電設備效率(lv)(lv)。隨著(zhu)新能(neng)源(yuan)(yuan)(yuan)占比不斷提高(gao),源(yuan)(yuan)(yuan)荷兩(liang)側(ce)的(de)工況(kuang)波動進一(yi)步增大,按傳統平(ping)(ping)衡(heng)(heng)配置原(yuan)則建設的(de)發(fa)(fa)輸變(bian)(bian)電設備利用(yong)效率(lv)(lv)將不斷下降,推高(gao)電力系統運行成(cheng)本。若電氫深度融(rong)合發(fa)(fa)展,可(ke)彌(mi)補電力供需即時平(ping)(ping)衡(heng)(heng)的(de)缺陷,通(tong)過儲氣罐等(deng)存儲、釋(shi)放氫氣的(de)緩(huan)沖作(zuo)(zuo)用(yong)增加平(ping)(ping)衡(heng)(heng)柔性。近中期電制氫負(fu)荷可(ke)作(zuo)(zuo)為柔性負(fu)荷參與(yu)電力需求響應;遠期隨著(zhu)氫發(fa)(fa)電技術的(de)成(cheng)熟還(huan)可(ke)發(fa)(fa)揮(hui)儲能(neng)、虛擬電廠作(zuo)(zuo)用(yong),同(tong)步平(ping)(ping)抑電源(yuan)(yuan)(yuan)、負(fu)荷兩(liang)側(ce)波動,提高(gao)發(fa)(fa)輸變(bian)(bian)電設備的(de)利用(yong)效率(lv)(lv),降低系統運行成(cheng)本。

  空(kong)間維度上,通(tong)過(guo)輸(shu)(shu)(shu)(shu)氫(qing)(qing)(qing)(qing)(qing)(qing)輸(shu)(shu)(shu)(shu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)綜合(he)優化,“宜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)則(ze)(ze)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)、宜氫(qing)(qing)(qing)(qing)(qing)(qing)則(ze)(ze)氫(qing)(qing)(qing)(qing)(qing)(qing)”,緩解(jie)(jie)大規模(mo)、遠距離送電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)力(li)(li),提升電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)(wang)安(an)全(quan)穩定水平(ping)及(ji)運(yun)行效率。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)氫(qing)(qing)(qing)(qing)(qing)(qing)融(rong)合(he)通(tong)過(guo)“電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)—氫(qing)(qing)(qing)(qing)(qing)(qing)—電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)”跨區(qu)域大循環,將電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)(wang)難以(yi)(yi)外送的(de)(de)新(xin)(xin)能(neng)(neng)源轉為(wei)氫(qing)(qing)(qing)(qing)(qing)(qing)能(neng)(neng)或氫(qing)(qing)(qing)(qing)(qing)(qing)基燃料,經公路、鐵(tie)路、航運(yun)、管(guan)道等(deng)(deng)廣義(yi)的(de)(de)氫(qing)(qing)(qing)(qing)(qing)(qing)網(wang)(wang)直接送入長(chang)三角、珠三角、京津(jin)冀等(deng)(deng)負荷(he)(he)中(zhong)心(xin)發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian),變(bian)(bian)“電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)從遠方來”為(wei)“電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)從身(shen)邊來”,既打通(tong)了(le)新(xin)(xin)能(neng)(neng)源大規模(mo)開發(fa)瓶頸,也(ye)緩解(jie)(jie)了(le)遠距離集中(zhong)送電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)所造(zao)成(cheng)(cheng)(cheng)的(de)(de)壓(ya)力(li)(li)和(he)風險(xian),還對受端電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)(wang)形成(cheng)(cheng)(cheng)更強有力(li)(li)的(de)(de)本(ben)地(di)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源支撐,實現電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)(li)系統本(ben)質(zhi)安(an)全(quan)。此(ci)外,隨著電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)制氫(qing)(qing)(qing)(qing)(qing)(qing)、氫(qing)(qing)(qing)(qing)(qing)(qing)儲(chu)運(yun)、氫(qing)(qing)(qing)(qing)(qing)(qing)發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)等(deng)(deng)技術的(de)(de)進(jin)步,關鍵核心(xin)設備的(de)(de)高(gao)度集成(cheng)(cheng)(cheng)化和(he)整體撬裝(zhuang)化,讓(rang)其運(yun)輸(shu)(shu)(shu)(shu)和(he)裝(zhuang)卸將更加靈(ling)活(huo)(huo)。不僅氫(qing)(qing)(qing)(qing)(qing)(qing)能(neng)(neng)本(ben)身(shen)可以(yi)(yi)通(tong)過(guo)管(guan)束車運(yun)輸(shu)(shu)(shu)(shu)和(he)轉供,甚至(zhi)連(lian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)氫(qing)(qing)(qing)(qing)(qing)(qing)融(rong)合(he)成(cheng)(cheng)(cheng)套設備也(ye)可以(yi)(yi)實現空(kong)間的(de)(de)轉移和(he)重(zhong)新(xin)(xin)分(fen)配,從而極大地(di)拓(tuo)展電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)(wang)和(he)氫(qing)(qing)(qing)(qing)(qing)(qing)網(wang)(wang)靈(ling)活(huo)(huo)互(hu)濟(ji)(ji)空(kong)間。當局部地(di)區(qu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)(li)負荷(he)(he)大幅增長(chang)時(shi),氫(qing)(qing)(qing)(qing)(qing)(qing)能(neng)(neng)供給路徑可重(zhong)新(xin)(xin)規劃為(wei)發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)騰出容量空(kong)間,從而取消或延遲新(xin)(xin)建(jian)變(bian)(bian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)站或擴建(jian)變(bian)(bian)壓(ya)器、線(xian)路等(deng)(deng),提高(gao)輸(shu)(shu)(shu)(shu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)走廊、變(bian)(bian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)站址資源緊張地(di)區(qu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)(wang)資產的(de)(de)利(li)用(yong)率和(he)經濟(ji)(ji)性。

    三是(shi)電氫融(rong)合可助力終端能(neng)源消費脫碳,進(jin)一步強化新(xin)型(xing)電力系(xi)統在現代能(neng)源體(ti)系(xi)中的樞紐作用。

  化石能(neng)(neng)源發(fa)電(dian)(dian)(dian)將(jiang)(jiang)逐(zhu)步被氫(qing)(qing)(qing)能(neng)(neng)發(fa)電(dian)(dian)(dian)取代(dai)(dai)。高比例(li)新能(neng)(neng)源發(fa)電(dian)(dian)(dian)的(de)隨機(ji)性、波動性導致(zhi)電(dian)(dian)(dian)力系(xi)統在未(wei)來(lai)相當長一段時期內仍(reng)離不(bu)開煤電(dian)(dian)(dian)、氣(qi)電(dian)(dian)(dian)等化石能(neng)(neng)源發(fa)電(dian)(dian)(dian)所發(fa)揮的(de)兜底(di)保障及靈活(huo)調節作用。而氫(qing)(qing)(qing)能(neng)(neng)或(huo)(huo)氫(qing)(qing)(qing)基(ji)燃料(氨(an)、甲(jia)醇(chun)、甲(jia)烷)同(tong)樣具備煤、氣(qi)等燃料型能(neng)(neng)源發(fa)電(dian)(dian)(dian)的(de)主要優勢,終端消費過程則零碳(tan)(tan)或(huo)(huo)低碳(tan)(tan)。隨著氫(qing)(qing)(qing)能(neng)(neng)生產(chan)、儲運(yun)及發(fa)電(dian)(dian)(dian)技術不(bu)斷突破(po),氫(qing)(qing)(qing)燃機(ji)容量增(zeng)大、成本(ben)下降、氫(qing)(qing)(qing)網全面鋪(pu)開、大規模氫(qing)(qing)(qing)能(neng)(neng)安全存儲商業化,氫(qing)(qing)(qing)能(neng)(neng)發(fa)電(dian)(dian)(dian)將(jiang)(jiang)從氫(qing)(qing)(qing)儲能(neng)(neng)、煤摻氨(an)、氣(qi)摻氫(qing)(qing)(qing)等,逐(zhu)步過渡到氫(qing)(qing)(qing)燃機(ji)替(ti)代(dai)(dai)調峰氣(qi)電(dian)(dian)(dian)、熱電(dian)(dian)(dian)聯產(chan)等,最終替(ti)代(dai)(dai)退役中小煤機(ji)乃至存量大型煤電(dian)(dian)(dian)。

  氫(qing)能(neng)替(ti)代也是(shi)其他行業終端能(neng)源(yuan)脫碳的重要途徑。除電力(li)外,工業、交通、建筑等也是(shi)我國(guo)碳排放(fang)的重要來源(yuan),分(fen)別占能(neng)源(yuan)活(huo)動碳排放(fang)量的37.5%、10%、10%左右。氫(qing)既是(shi)重要的化(hua)工原(yuan)料(liao),又是(shi)優質的燃料(liao),可通過燃料(liao)替(ti)代和原(yuan)料(liao)替(ti)代等形式,減少工業、交通、建筑等領(ling)域的化(hua)石能(neng)源(yuan)消費,助力(li)其低(di)碳轉型。

  綠(lv)(lv)氫(qing)替(ti)(ti)代將加快(kuai)推動(dong)電(dian)(dian)(dian)氫(qing)融合,打造(zao)以(yi)電(dian)(dian)(dian)為(wei)核心的(de)綠(lv)(lv)色能源樞紐。在(zai)“雙碳(tan)”目標推動(dong)下,氫(qing)能供(gong)需兩端均有強烈的(de)碳(tan)減排需求,綠(lv)(lv)氫(qing)替(ti)(ti)代灰氫(qing)是大勢所趨。以(yi)當前全國(guo)年(nian)消費(fei)3300萬噸氫(qing)氣為(wei)例,若全部(bu)采(cai)用可(ke)再生能源發(fa)電(dian)(dian)(dian)制(zhi)氫(qing)替(ti)(ti)代,按每標方5千瓦(wa)時電(dian)(dian)(dian)測算,年(nian)需電(dian)(dian)(dian)量達1.85萬億千瓦(wa)時。綠(lv)(lv)氫(qing)有望成為(wei)未來電(dian)(dian)(dian)力(li)需求增長的(de)重要驅動(dong)力(li)。

  電氫融合應用場景設想

  從(cong)電(dian)(dian)源(yuan)(yuan)(yuan)側(ce)分析。近期場景是風光制(zhi)(zhi)氫耦合(he)(he)化工(gong)、鋼(gang)鐵,改(gai)善電(dian)(dian)源(yuan)(yuan)(yuan)特性(xing)、促進風光消納。可(ke)再生能(neng)(neng)源(yuan)(yuan)(yuan)富(fu)集(ji)地(di)(di)區電(dian)(dian)力邊際成本(ben)較低,風光制(zhi)(zhi)氫供(gong)給周(zhou)邊化工(gong)、鋼(gang)鐵等(deng)用(yong)氫大(da)戶(hu)具(ju)有一定的(de)成本(ben)優勢,且可(ke)降(jiang)低用(yong)戶(hu)對外(wai)來原材料的(de)依(yi)賴、助力其深度脫碳,并從(cong)改(gai)善新(xin)能(neng)(neng)源(yuan)(yuan)(yuan)出(chu)力特性(xing)中獲得(de)收益,有望最早實現經濟可(ke)行性(xing),是近期電(dian)(dian)源(yuan)(yuan)(yuan)側(ce)電(dian)(dian)氫融合(he)(he)的(de)主要(yao)應用(yong)場景。遠期場景是可(ke)再生能(neng)(neng)源(yuan)(yuan)(yuan)就(jiu)(jiu)地(di)(di)轉換為氫基(ji)燃料,輸(shu)氫輸(shu)電(dian)(dian)并舉,支撐新(xin)能(neng)(neng)源(yuan)(yuan)(yuan)全面替代化石(shi)能(neng)(neng)源(yuan)(yuan)(yuan)。隨(sui)著電(dian)(dian)制(zhi)(zhi)氫、氫發電(dian)(dian)等(deng)技術(shu)進步和(he)成本(ben)下降(jiang),西部(bu)豐(feng)富(fu)的(de)新(xin)能(neng)(neng)源(yuan)(yuan)(yuan)可(ke)就(jiu)(jiu)地(di)(di)轉換為氫基(ji)燃料,供(gong)給氫燃氣輪(lun)機發電(dian)(dian)需要(yao),徹底解決新(xin)能(neng)(neng)源(yuan)(yuan)(yuan)隨(sui)機性(xing)、間(jian)歇性(xing)的(de)問題。此(ci)外(wai),還可(ke)通過公路(lu)、鐵路(lu)、航(hang)運、管(guan)道等(deng)將氫基(ji)燃料直(zhi)送(song)負荷中心(xin),與(yu)輸(shu)電(dian)(dian)并舉,滿足(zu)西部(bu)清(qing)潔能(neng)(neng)源(yuan)(yuan)(yuan)向中東部(bu)、南部(bu)負荷中心(xin)大(da)范圍優化配置的(de)需要(yao)。

  從(cong)電(dian)(dian)(dian)(dian)網(wang)(wang)側分析(xi)。近期場(chang)景(jing)是采用開(kai)環流動的(de)“電(dian)(dian)(dian)(dian)—氫(qing)(qing)(qing)(qing)”模(mo)式(shi),搭配儲(chu)氫(qing)(qing)(qing)(qing)罐以(yi)大型可(ke)調負荷(he)形態服(fu)(fu)務(wu)電(dian)(dian)(dian)(dian)網(wang)(wang)與氫(qing)(qing)(qing)(qing)網(wang)(wang)。當前技術條件(jian)和市場(chang)環境下(xia),電(dian)(dian)(dian)(dian)網(wang)(wang)側氫(qing)(qing)(qing)(qing)儲(chu)能的(de)經濟性仍較差(cha),建議以(yi)電(dian)(dian)(dian)(dian)制(zhi)氫(qing)(qing)(qing)(qing)形態通過儲(chu)氫(qing)(qing)(qing)(qing)罐作為(wei)大型可(ke)調負荷(he)支(zhi)撐電(dian)(dian)(dian)(dian)網(wang)(wang),利用氫(qing)(qing)(qing)(qing)能大規模(mo)、長周期的(de)儲(chu)能特(te)性,耦(ou)合氫(qing)(qing)(qing)(qing)能用戶為(wei)電(dian)(dian)(dian)(dian)網(wang)(wang)提(ti)(ti)供輔助(zhu)服(fu)(fu)務(wu)、應急備用等,提(ti)(ti)升(sheng)綜合收益。遠期場(chang)景(jing)是采用閉(bi)環流動的(de)“電(dian)(dian)(dian)(dian)—氫(qing)(qing)(qing)(qing)—電(dian)(dian)(dian)(dian)”模(mo)式(shi),搭配儲(chu)氫(qing)(qing)(qing)(qing)罐以(yi)源(yuan)(yuan)、荷(he)雙重形態服(fu)(fu)務(wu)電(dian)(dian)(dian)(dian)網(wang)(wang)與氫(qing)(qing)(qing)(qing)網(wang)(wang)。一方面,通過電(dian)(dian)(dian)(dian)制(zhi)氫(qing)(qing)(qing)(qing)平衡功率,將(jiang)滿足就地發電(dian)(dian)(dian)(dian)需求(qiu)以(yi)外的(de)富余氫(qing)(qing)(qing)(qing)氣(qi)支(zhi)撐不同領域的(de)下(xia)游(you)應用,提(ti)(ti)升(sheng)各(ge)行(xing)業減(jian)碳強度(du);另(ling)一方面,通過氫(qing)(qing)(qing)(qing)發電(dian)(dian)(dian)(dian)為(wei)電(dian)(dian)(dian)(dian)網(wang)(wang)提(ti)(ti)供調峰、調頻(pin)、備用等輔助(zhu)服(fu)(fu)務(wu)支(zhi)持(chi),且電(dian)(dian)(dian)(dian)氫(qing)(qing)(qing)(qing)融合系(xi)統(tong)具有時空平移(yi)特(te)性,電(dian)(dian)(dian)(dian)制(zhi)氫(qing)(qing)(qing)(qing)和氫(qing)(qing)(qing)(qing)發電(dian)(dian)(dian)(dian)2個環節能夠異地分時運(yun)行(xing),更(geng)好滿足系(xi)統(tong)在時空上對靈(ling)活(huo)調節資源(yuan)(yuan)的(de)需求(qiu)。

  從用(yong)(yong)戶側(ce)(ce)(ce)分析。近期(qi)(qi)場(chang)景(jing)是分布式(shi)(shi)(shi)就地制氫(qing)(qing)參與需(xu)(xu)求響(xiang)(xiang)應(ying)(ying)(ying),提升(sheng)系統調節(jie)能(neng)力(li)和加氫(qing)(qing)站競爭力(li)。電制氫(qing)(qing)響(xiang)(xiang)應(ying)(ying)(ying)速度快(kuai)、調節(jie)范圍寬,且對電價(jia)極其敏感,參與電力(li)需(xu)(xu)求響(xiang)(xiang)應(ying)(ying)(ying)意愿強烈。因此,在(zai)現有的(de)技術條件下,負荷(he)(he)側(ce)(ce)(ce)試點(dian)分布式(shi)(shi)(shi)就地制氫(qing)(qing)參與需(xu)(xu)求響(xiang)(xiang)應(ying)(ying)(ying)是較合(he)適的(de),通過合(he)適的(de)價(jia)格信號引導其參與需(xu)(xu)求響(xiang)(xiang)應(ying)(ying)(ying),可(ke)顯著平抑電網(wang)的(de)負荷(he)(he)波動。遠(yuan)期(qi)(qi)場(chang)景(jing)是“分布式(shi)(shi)(shi)電制氫(qing)(qing)+氫(qing)(qing)燃(ran)料電池(chi)”在(zai)用(yong)(yong)戶側(ce)(ce)(ce)廣泛應(ying)(ying)(ying)用(yong)(yong),產消一體(ti)負荷(he)(he)大(da)(da)量(liang)(liang)涌現,源荷(he)(he)、網(wang)荷(he)(he)互動能(neng)力(li)大(da)(da)幅(fu)提升(sheng)。隨著以光(guang)伏為代表的(de)分布式(shi)(shi)(shi)電源快(kuai)速發展,在(zai)用(yong)(yong)戶側(ce)(ce)(ce)大(da)(da)量(liang)(liang)建設(she)電制氫(qing)(qing)裝置和氫(qing)(qing)燃(ran)料電池(chi),形(xing)成產消一體(ti)負荷(he)(he),快(kuai)速響(xiang)(xiang)應(ying)(ying)(ying)不匹配電量(liang)(liang),提升(sheng)負荷(he)(he)靈活(huo)互動能(neng)力(li),推動多能(neng)源品種(zhong)互聯互補。
