Research on Optimal Configuration of Charging Modes of Electric Vehicles Based on Charging Power Levels

针对电动汽车无序充电对电网的影响,文章提出了一种基于充电功率等级的电动汽车充电方式优化配置方案,分析了电动汽车充电行为,阐述了电动汽车无序充电对电网的影响。该方案以电动汽车总设备投资成本最低和充电负荷的峰谷差最小为目标,得到了既能满足用户需求,也能减少设备投资,降低电动汽车无序充电负荷峰谷差的不同充电功率等级的比例。

In view of the influence of the disordered charging of electric vehicle charging on the power grid, this paper puts forward an optimal configuration scheme of charging modes of electric vehicles based on charging power levels, analyzes the charging behavior of electric vehicles, and expounds the influence of the disordered charging of electric vehicles on the power grid. The scheme aims at the lowest total equipment investment cost of electric vehicles and minimum peak-to-valley difference of charging loads, and obtains the proportions of different charging power levels that can meet the demands of users, reduce equipment investment, and reduce the peak-to-valley difference of disordered charging loads of electric vehicles.
