摘要

针对大规模电动汽车的无序充电行为可能导致电网出现的三相不平衡问题,基于演化动态博弈模型,提出一种考虑三相负荷平衡和光伏消纳的电动汽车充电调度策略。首先,基于电动汽车接入时段的主观性以及光伏出力和负荷的不确定性,引入游牧集群和定居集群之间的演化动态博弈方程;然后,考虑用户侧和电网侧双方利益关系,设计以最小化电动汽车充电费用、三相负荷不平衡度和无功需求为目标的调度优化模型;最后,通过对某商业区配电网算例进行仿真求解,对比分析三相有功曲线、三相无功曲线以及荷电状态曲线的变化趋势。算例结果表明,该调度策略可有效降低三相不平衡度,满足无功补偿的需求以及改善用户充电成本。

Abstract

Aiming at the three-phase unbalance problem in the power grid that may be caused by the disorderly charging behavior of large-scale electric vehicles, a charging scheduling strategy for electric vehicles that considers three-phase load balance and photovoltaic consumption based on an evolutionary dynamic game model is proposed. First, based on the subjectivity of EV period for connecting to the grid and the uncertainty of PV output and load, the evolutionary dynamic game equation between nomad populations and sedentary populations is constructed. Then, considering the interests of both the user and the grid, a dispatching optimization model is designed to minimize the charging cost of electric vehicles, three-phase load imbalance and reactive power demand. Finally, by simulating and solving a distribution network example in a commercial area, the three-phase active power curve, the three-phase reactive power curve and the change trend of the state of charge curve are compared and analyzed. The results of the calculation example show that the dispatching strategy can effectively reduce the three-phase unbalance, meet the needs of reactive power compensation and improve the charging cost of users.
