    摘 要:明确电动汽车充电负荷特性,是开展电动汽车有序充放电研究的基础工作。结合实际数据,开展低压居民台区电动汽车充电负荷研究,对某市小区的实际负荷数据进行收集和预处理,针对电动汽车分析需求构建负荷特性评价指标体系,用于分析电动汽车充电负荷特性,并通过分析得到实际负荷中“峰上加峰”现象出现频率低于预期和负荷峰值相较于配变上限较小的结论,与现有直观认识存在差异。同时基于电动汽车发展趋势对未来进行预测,得到未来充电负荷将持续增长,可能成为新的负荷高峰的结论。

    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
