The invention belongs to the technical field of charging control, and particularly relates to a transformer area power transformation and distribution network charging control method and system. The method comprises the following steps: acquiring a real-time electrical load and an average electrical load of a transformer in a zone area in a current time period, and determining a load state grade of the transformer in the zone area based on the real-time electrical load and the average electrical load of the transformer in the current time period and a rated power of the transformer in the zone area; calculating the available power allocated to the charging equipment under the corresponding load state level, and calculating the maximum output power of each charging equipment in the next time period according to the available power allocated to the charging equipment and the number of the charging equipment in the charging state in the transformer area in the current time period; and in the next time period, each charging device in the charging state is controlled to output power by taking the maximum output power of the charging device as a limit value, so that the calculation error and the requirements on the reliability and the calculation capability of the charging management platform are reduced.

    本发明属于充电控制技术领域,具体涉及一种台区变配网充电控制方法及系统。该方法包括:获取当前时间周期内台区变压器的实时用电负荷和平均用电负荷,基于当前时间周期内台区变压器的实时用电负荷、平均用电负荷和台区变压器的额定功率确定台区变压器的负荷状态等级;计算对应负荷状态等级下调配至充电设备的可用功率,根据调配至充电设备的可用功率和当前时间周期内台区处于充电状态的充电设备数量计算下一时间周期内各充电设备的最大输出功率;在下一时间周期内,控制处于充电状态的各充电设备以充电设备的最大输出功率为限值进行功率输出,降低了计算误差和对充电管理平台可靠性、计算能力的要求。
