本文通过分析不同类型电动汽车充电行为的差异，研究电动汽车的层次分类。根据常规充电电动汽车和快速充电电动汽车的不同比例，提出了四个指标（高峰负荷增量、高峰负荷持续时间、负荷曲线最大平滑指数和平均平滑指数）来评估对配电网的影响。然后建立了不同充电方式下电动汽车比例的配置方法。最后，基于某配电网现场数据和IEEE-34节点算例，结合充电负荷蒙特卡罗模拟，得出不同充电方式下电动汽车的最佳配比。结果表明，不同充电方式的电动汽车合适的配比可以使负荷曲线更加平滑，电网峰谷负荷差异显着减小。
This paper studies the hierarchical classification of electric vehicles (EV) by analyzing the differences of charging behaviors of different types of EVs. According to the different proportions of conventionally-charged EVs and fast-charged EVs, four indexes (the increment of peak load, the duration of peak load, the maximum smoothing index of load curve and the average smoothing index) are proposed to evaluate the impact on the distribution network. Then a method is established to configure the proportion of EV in different charging methods. Finally, based on the field data of a distribution network and the IEEE-34 node example, the optimal proportion of EV in different charging methods are made combined with the Monte Carlo simulation of charging load. Results show that suitable ratio of EV with different charging methods can make the load curve smoother and the grid's difference between peak and valley loads decrease significantly.
