The invention provides a charging power adjusting method and system, and belongs to the technical field of electric power. The method is applied to a first controller in a charging adjustment system.The method comprises: the first controller obtaining electrical data, collected by a collection device, of a transformer; respectively receiving power resource data and charging data of each charginggroup sent by a plurality of second controllers; calculating transformer total load data and droop coefficients corresponding to the charging groups by adopting a preset droop algorithm according to the electrical data, the power resource data and the charging data; and sending the total load data of the transformer and the droop coefficient corresponding to each charging group to a second controller, so that the second controller adjusts the power of the corresponding charging group according to the total load data of the transformer and the droop coefficient corresponding to each charging group. The equipment utilization rate and the operation safety of the power system can be improved.

    本发明提供一种充电功率调节方法及系统,属于电力技术领域。该方法应用于充电调节系统中的第一控制器,该方法包括:第一控制器获取采集装置采集的变压器的电气数据;分别接收多个第二控制器发送的各充电群组的功率资源数据以及充电数据;采用预设下垂算法,根据电气数据、功率资源数据以及充电数据,计算变压器总负荷数据以及各充电群组对应的下垂系数;向第二控制器发送变压器总负荷数据以及各充电群组对应的下垂系数,以使第二控制器根据变压器总负荷数据以及各充电群组对应的下垂系数调节对应充电群组的功率。本发明可以提高电力系统的设备利用率和运行安全性。
