近日，云(yun)(yun)(yun)南(nan)電力(li)(li)技術(shu)有限(xian)責(ze)任(ren)公(gong)司與南(nan)方電網云(yun)(yun)(yun)南(nan)電動汽車服務有限(xian)公(gong)司合作共建的全省首個“光儲直柔+全直流充電樁一體化系統”在云(yun)(yun)(yun)南(nan)電力(li)(li)技術(shu)公(gong)司能源技術(shu)科技創新園正式投運。
作為(wei)省(sheng)內首個集光(guang)伏(fu)、儲(chu)能(neng)(neng)、直(zhi)流(liu)(liu)配電(dian)(dian)(dian)、柔(rou)性負(fu)荷(he)與(yu)充(chong)(chong)電(dian)(dian)(dian)樁協同控制于(yu)一體的(de)示范(fan)項(xiang)目(mu)，該(gai)系(xi)(xi)統(tong)通過源網(wang)荷(he)儲(chu)充(chong)(chong)多能(neng)(neng)互補技(ji)術，實現了清潔能(neng)(neng)源高(gao)效消納(na)與(yu)園區(qu)(qu)用(yong)能(neng)(neng)柔(rou)性調(diao)節，為(wei)低(di)碳園區(qu)(qu)建(jian)(jian)設樹立了新(xin)標桿。該(gai)項(xiang)目(mu)采用(yong)全(quan)直(zhi)流(liu)(liu)能(neng)(neng)源架(jia)構，總配電(dian)(dian)(dian)容量達700kW，覆(fu)蓋DC750V至DC48V多級直(zhi)流(liu)(liu)電(dian)(dian)(dian)壓，構建(jian)(jian)“光(guang)伏(fu)發(fa)電(dian)(dian)(dian)—儲(chu)能(neng)(neng)調(diao)峰—直(zhi)流(liu)(liu)用(yong)電(dian)(dian)(dian)—柔(rou)性調(diao)節”的(de)閉環生態。光(guang)伏(fu)系(xi)(xi)統(tong)創新(xin)融合單晶(jing)硅(gui)屋頂(ding)網(wang)架(jia)、碲(di)化鎘發(fa)電(dian)(dian)(dian)玻(bo)璃(li)幕墻(qiang)，形成立體化發(fa)電(dian)(dian)(dian)矩陣(zhen)，搭配100kW/200kWh儲(chu)能(neng)(neng)系(xi)(xi)統(tong)，實現光(guang)伏(fu)發(fa)電(dian)(dian)(dian)“削峰填谷”。柔(rou)性直(zhi)流(liu)(liu)負(fu)荷(he)涵蓋智能(neng)(neng)設備、照(zhao)明系(xi)(xi)統(tong)、充(chong)(chong)電(dian)(dian)(dian)樁等(deng)，較傳統(tong)交流(liu)(liu)系(xi)(xi)統(tong)降低(di)電(dian)(dian)(dian)能(neng)(neng)轉換損耗(hao)超過15%。
該(gai)系(xi)統部署的5臺(tai)全直流(liu)充(chong)(chong)電(dian)(dian)樁中，1臺(tai)V2G充(chong)(chong)電(dian)(dian)樁具備“車—網”雙向(xiang)充(chong)(chong)放電(dian)(dian)功能(neng)(neng)，該(gai)技術突破標志著電(dian)(dian)動(dong)汽車從單一用(yong)能(neng)(neng)終端(duan)升(sheng)級為園(yuan)區柔性調節資源。通過(guo)光(guang)儲充(chong)(chong)智能(neng)(neng)互動(dong)平臺(tai)，充(chong)(chong)電(dian)(dian)樁可依據光(guang)伏出(chu)力與儲能(neng)(neng)狀態動(dong)態調節充(chong)(chong)放電(dian)(dian)功率，在光(guang)照充(chong)(chong)足時優(you)先消納綠(lv)電(dian)(dian)，在用(yong)電(dian)(dian)高峰反向(xiang)為園(yuan)區供電(dian)(dian)，年均可提(ti)升(sheng)綠(lv)電(dian)(dian)利用(yong)率10%以上。
據悉，該系統每(mei)年可提(ti)供清潔電(dian)力超20萬度，節約標準煤約70噸，減少(shao)二氧(yang)化碳排(pai)放約176噸。通過(guo)多電(dian)壓等級直流微(wei)電(dian)網，實(shi)現分布式(shi)能源就(jiu)地消納(na)與精(jing)準調配(pei)，V2G充電(dian)樁的接入讓(rang)新能源汽車成為“移動儲能站”，為未來虛擬電(dian)廠建設奠定(ding)基(ji)礎。
