摘　　要：电动汽车(Electric vehicles,EV)的大规模部署对配电系统运行产生了不利影响,电动汽车充电站(EV charging stations,EVCS)安装位置不合理会降低配电系统的电能质量,影响电网安全稳定运行。在配电网电能质量分析的基础上,本文提出了一种用于EVCS优化选址的可靠性指数(Reliability index,RI)策略。针对IEEE-33标准系统的EVCS选址问题,设置了多个典型测试场景,突出电能质量,对慢速/快速充电桩-EVCS对系统运行工况影响进行了谐波分析。所有测试结果表明RI策略在配电系统中设置慢速/快速充电桩-EVCS的应用中具有一定作用。最后,基于某实时配电系统的算例仿真验证了所提EVCS优化选址方法的有效性。The large-scale deployment of electric vehicles(EVs)has a negative impact on the operation of distribution systems.Improper installation of EV charging stations(EVCS)reduces the power quality and affect the safe and stable operation of the power grid.Based on the analysis of power quality in distribution networks,this paper proposes a reliability index(RI)strategy for optimizing EVCS location selection.Aiming at the EVCS location problem of IEEE-33 standard system,several typical test cases were set to highlight power quality,and harmonic analysis was conducted on the impact of slow/fast chargers-EVCS on system operating conditions.All test results indicate that the RI strategy has a certain role in the application of setting slow/fast chargers-EVCS in distribution systems.Finally,the effectiveness of the proposed EVCS optimization of location selection method was verified based on a real-time distribution system.
