规模化电动汽车充电对配电网电压质量的影响及其对策

Impact of Large-scale Electric Vehicle Charging on Voltage Quality of Distribution Network and Relevant Countermeasures

  • 摘要: 随着电动汽车的逐渐普及,利用安装在小区停车场、公共停车场、单位停车场等区域内的充电桩进行常规充电将成为电动汽车充电的主流模式,规模化的分布式充电势必对配电网的电压质量产生影响。该文概述了电动汽车充电机类型与充电模式,分析了规模化电动汽车充电引起的配电网电压质量问题,包括谐波污染、电压下降和三相电压不平衡问题。探讨了有序充电控制策略、电动汽车充电与分布式电源协调控制以及V2G模式对改善配电网电压质量的作用,并展望了相关领域的下一步研究工作。

     

    Abstract: :With the increasing popularity of electric vehicle, regular charging using charging piles installed in residential parking lot, public parking lot, unit parking lot and other areal will become the mainstream mode of electric vehicle charging. Large-scale distributed charging is bound to have an impact on the voltage quality of distribution network. This paper summarizes the types of electric vehicle chargers and charging modes, and the voltage quality problems of distribution network caused by large-scale electric vehicle charging, which include such issues as harmonic pollution, voltage drops and three-phase voltage imbalance. The influences of the control strategy of orderly charging, the coordination control of electric vehicle charging and distributed power supply, and the V2G model on the voltage quality improving of distribution network are explored, and the next research work in related fields is looked forward to.
