近日，云(yun)(yun)南電(dian)(dian)力技術有限(xian)責任公司與南方電(dian)(dian)網云(yun)(yun)南電(dian)(dian)動汽車服務有限(xian)公司合作共建的全省首個“光儲直(zhi)柔+全直(zhi)流(liu)充電(dian)(dian)樁(zhuang)一體化系統(tong)”在云(yun)(yun)南電(dian)(dian)力技術公司能源技術科技創(chuang)新園正式投運。
作(zuo)為省內(nei)首個集(ji)光伏(fu)、儲能(neng)(neng)、直流(liu)配(pei)電(dian)(dian)(dian)、柔性(xing)負荷與充(chong)電(dian)(dian)(dian)樁協同控制于(yu)一(yi)體的(de)示范項目，該系統通過源網荷儲充(chong)多(duo)能(neng)(neng)互補技(ji)術，實(shi)現了(le)清(qing)潔能(neng)(neng)源高效消納與園區用(yong)能(neng)(neng)柔性(xing)調(diao)節(jie)，為低碳園區建設(she)(she)樹立了(le)新(xin)標桿。該項目采(cai)用(yong)全直流(liu)能(neng)(neng)源架構(gou)(gou)，總配(pei)電(dian)(dian)(dian)容(rong)量(liang)達700kW，覆蓋DC750V至DC48V多(duo)級直流(liu)電(dian)(dian)(dian)壓，構(gou)(gou)建“光伏(fu)發電(dian)(dian)(dian)—儲能(neng)(neng)調(diao)峰—直流(liu)用(yong)電(dian)(dian)(dian)—柔性(xing)調(diao)節(jie)”的(de)閉環生態。光伏(fu)系統創新(xin)融合單(dan)晶硅屋頂網架、碲化鎘(ge)發電(dian)(dian)(dian)玻璃幕墻，形(xing)成立體化發電(dian)(dian)(dian)矩(ju)陣，搭(da)配(pei)100kW/200kWh儲能(neng)(neng)系統，實(shi)現光伏(fu)發電(dian)(dian)(dian)“削(xue)峰填谷(gu)”。柔性(xing)直流(liu)負荷涵蓋智能(neng)(neng)設(she)(she)備、照明系統、充(chong)電(dian)(dian)(dian)樁等(deng)，較傳統交(jiao)流(liu)系統降低電(dian)(dian)(dian)能(neng)(neng)轉換損耗超過15%。
該(gai)系統(tong)部署(shu)的5臺全直(zhi)流充電(dian)(dian)樁中，1臺V2G充電(dian)(dian)樁具備“車—網(wang)”雙(shuang)向充放電(dian)(dian)功能(neng)，該(gai)技術突破標(biao)志著電(dian)(dian)動汽(qi)車從單一用(yong)能(neng)終端升級為(wei)園區柔性調節(jie)資源。通過光(guang)儲(chu)(chu)充智能(neng)互(hu)動平(ping)臺，充電(dian)(dian)樁可依據光(guang)伏出(chu)力與儲(chu)(chu)能(neng)狀(zhuang)態(tai)動態(tai)調節(jie)充放電(dian)(dian)功率，在光(guang)照充足時優先消(xiao)納綠(lv)電(dian)(dian)，在用(yong)電(dian)(dian)高峰(feng)反向為(wei)園區供電(dian)(dian)，年均可提升綠(lv)電(dian)(dian)利用(yong)率10%以上(shang)。
據悉，該系統每(mei)年(nian)可提(ti)供清潔電(dian)(dian)力超20萬度，節約(yue)標(biao)準(zhun)煤約(yue)70噸(dun)，減少二氧化碳排放約(yue)176噸(dun)。通(tong)過(guo)多(duo)電(dian)(dian)壓等(deng)級直流微電(dian)(dian)網，實現分(fen)布式(shi)能源就地消納與精準(zhun)調配，V2G充(chong)電(dian)(dian)樁(zhuang)的(de)接入讓新能源汽車成為(wei)“移動(dong)儲能站”，為(wei)未(wei)來虛擬電(dian)(dian)廠建設奠定基(ji)礎(chu)。
