The invention belongs to the technical field of new energy photovoltaic energy storage charging, and relates to an electric vehicle charging station power supply system and method. A photovoltaic power generation system comprises a plurality of distributed photovoltaic power stations in a district, and in a topological structure of each distributed photovoltaic power station, the distributed photovoltaic power stations are connected with an electric vehicle charging station to be powered in the district through a DC/DC converter; the control system is in communication connection with the photovoltaic power generation system and the to-be-powered electric vehicle charging station, comprises a data acquisition module, a power prediction module and a first power dispatching module, and predicts the electric power of the to-be-powered electric vehicle charging station at the t + 1 moment and the available power of each distributed photovoltaic power station; the distance between the distributed photovoltaic power stations and the to-be-powered electric vehicle charging station is closest, and the sum of the available power at the t + 1 moment is larger than or equal to the electric power of the to-be-powered electric vehicle charging station, so that the power transmission loss is reduced, and the power grid stability is improved.

    本发明属于新能源光伏储能充电技术领域,涉及一种电动汽车充电站供电系统及方法:光伏发电系统,包括台区内多个分布式光伏发电站,每个分布式光伏发电站的拓扑结构中,至少包括通过DC/DC转换器与台区内一待供电电动汽车充电站相连;控制系统,与光伏发电系统和待供电电动汽车充电站通信连接,包括数据采集模块、功率预测模块和第一电力调度模块,通过预测待t+1时刻供电电动汽车充电站用电功率以及各个分布式光伏发电站的可用功率,控制n个与待供电电动汽车充电站的距离最近、且t+1时刻的可用功率之和大于等于待供电电动汽车充电站的用电功率的分布式光伏发电站向待供电电动汽车充电站供电,减少了电力传输损耗,提高了电网稳定性。
