    摘 要:明確電動汽車充電負荷特性,是開展電動汽車有序充放電研究的基礎(chǔ)工作。結(jié)合實際數(shù)據(jù),開展低壓居民臺區(qū)電動汽車充電負荷研究,對某市小區(qū)的實際負荷數(shù)據(jù)進行收集和預(yù)處理,針對電動汽車分析需求構(gòu)建負荷特性評價指標體系,用于分析電動汽車充電負荷特性,并通過分析得到實際負荷中“峰上加峰”現(xiàn)象出現(xiàn)頻率低于預(yù)期和負荷峰值相較于配變上限較小的結(jié)論,與現(xiàn)有直觀認識存在差異。同時基于電動汽車發(fā)展趨勢對未來進行預(yù)測,得到未來充電負荷將持續(xù)增長,可能成為新的負荷高峰的結(jié)論。

    Abstract: Clarifying the charging load characteristics of electric vehicles is the fundamental work for conducting research on the orderly charging and discharging of electric vehicles. Based on actual data,research on the charging load of electric vehicles in low-voltage residential distribution areas was carried out, and the actual load data of residential areas in a certain city were collected and preprocessed,then a load characteristic evaluation index system was constructed in response to the analysis requirements of electric vehicles to analyze the charging load characteristics of electric vehicles.Through the analysis, it was concluded that the frequency of the“peak on top of peak”phenomenon in the actual load was lower than expected and the load peak was smaller compared to the upper limit of the distribution transformer, which was different from the existing intuitive understanding. Meanwhile, based on the development trend of electric vehicles,the future is predicted, and the conclusion is drawn that the future charging load will continue to increase and may become a new load peak.
    Key words: electric vehicle; charging load; load characteristic; residential distribution area; prediction model
