The invention provides a control method and system of an intelligent charging pile supporting power grid frequency control, which can be applied to the technical field of power grid energy management. The method is applied to a charging pile and comprises the following steps: acquiring an operation state of the charging pile in a control area, an automobile state of an electric automobile connected with the charging pile and a power grid frequency of a power grid; determining frequency deviation of the power grid according to the power grid frequency of the power grid; when it is determined that the frequency deviation of the power grid is larger than a first set value, a low-frequency control strategy for the charging pile is generated based on the operation state of the charging pile and the automobile state of an electric automobile connected with the charging pile, and the low-frequency control strategy is used for the charging pile to transmit electric energy to the power grid to increase the power grid frequency of the power grid; and when it is determined that the frequency deviation of the power grid is smaller than a second set value, a high-frequency control strategy for the charging pile is generated based on the operation state of the charging pile and the automobile state of the electric automobile connected with the charging pile.

    本发明提供了一种支持电网频率控制的智能充电桩的控制方法及系统,可以应用于电网能源管理技术领域。该方法应用于充电桩,包括:获取控制区域内充电桩的运行状态、与充电桩连接的电动汽车的汽车状态以及电网的电网频率;根据电网的电网频率,确定电网的频率偏差;在确定电网的频率偏差大于第一设定值的情况下,基于充电桩的运行状态和与充电桩连接的电动汽车的汽车状态,生成针对充电桩的低频控制策略,低频控制策略用于充电桩向电网传输电能以升高电网的电网频率;在确定电网的频率偏差小于第二设定值的情况下,基于充电桩的运行状态和与充电桩连接的电动汽车的汽车状态,生成针对充电桩的高频控制策略。
