The invention discloses an electric vehicle and power grid interaction control method and system. The method comprises the steps that real-time load data of a charging station and the charging state, voltage, current and electric quantity data of charging equipment are obtained; and designing a first charging plan according to the real-time data, and generating an optimal charging control curve of each charging pile. Under the platform charging strategy, the optimal charging control curve is sent to the charging pile; and when the load exceeds the limit or the residual load is high, executing a local strategy, and periodically controlling charging. Through the mode, the stability of a power grid can be effectively improved, the operation cost is reduced, meanwhile, the charging requirement of an electric vehicle user is guaranteed, and harmonious symbiosis of a power system and an electric vehicle is achieved.
本发明公开了一种电动汽车与电网互动控制方法及系统包括:获取充电场站的实时负荷数据和充电设备的充电状态、电压、电流、电量数据。根据实时数据,设计第一充电计划,生成每台充电桩的最优充电控制曲线。平台充电策略下,发送最优充电控制曲线至充电桩;负荷超限或剩余负荷高时,执行本地策略,周期控制充电。通过上述方式,能够有效地提高电网的稳定性,降低运营成本,同时保证电动汽车用户的充电需求,实现电力系统和电动汽车的和谐共生。
