考虑季节因素的电动汽车充电负荷建模与优化充电

Modeling and Optimizing Charging of Electric Vehicle Charging Load Considering Seasonal Factors

不同季节的家用电动汽车充电负荷存在明显的差异,为精确分析电动汽车的接入对配电网的影响,通过分析用户的出行规律,建立了不同季节的电动汽车充电负荷模型。为减少电动汽车充电负荷对配电网带来的危害,建立了电动汽车充电的0-1整数规划模型,并给出了优化充电策略。最后以IEEE33节点配电系统为例,分析了采用全年平均值和分季节参数的电动汽车充电负荷对配电网的影响,仿真结果验证了优化充电策略的有效性和考虑季节因素建模的必要性。

There are obvious differences in the charging load of household electric vehicles in different seasons.In order to accurately analyze the impact of electric vehicle access on the distribution network,the electric vehicle charging load model in different seasons was established by analyzing the user's travel law.In order to reduce the harm caused by electric vehicle charging load to the distribution network,a 0-1 integer programming model for electric vehicle charging was established,and an optimized charging strategy was given.Finally,taking the IEEE33 node power distribution system as an example,the impact of the electric vehicle charging load on the distribution network using the annual average and seasonal parameters was analyzed.The simulation results verified the effectiveness of the optimized charging strategy and the necessity of modeling with seasonal factors.
