摘　　要：分析电动汽车参与V2G服务并网后对电网的影响。介绍了电动汽车充放电的特性,并分别从削峰填谷、负荷率、配电网电压3个方面阐述了电动汽车参与V2G服务并网后的有利前景。通过分析与验证,得到以下结论:电动汽车参与V2G服务并网后,对电网可起到削峰填谷的作用,同时可以增大负荷率,提高电力设备的利用率,对配电网可起到在低谷期降低线路电压、高峰期升高线路电压的作用,有利于电网的安全、稳定、经济运行。The influence of electric vehicle to power grid after its participation to V2G service connection is analyzed. Charging and discharging characteristics of electric vehicle are introduced. Favorable prospect of electric vehicle after its participation to V2G service connection is described from 3 aspects： peak load shifting, load rate and distribution network voltage. Based on analysis and verification, following conelusions are obtained： after the participation to V2G service connection, eleetrie vehicle can not only realize the peak load shifting function to power grid but also rise the load rate at the same and improve utilization rate of electric equipments, which can decrease the line voltage of distribution network in the low load period and increase the line voltage in the peak load period, and is benefit to the secure, stable and economic operation of power grid.
