The invention discloses a charging control method and device of an electric vehicle charging station suitable for new energy grid connection. According to the method, one day is divided into a plurality of time periods, for each time period, the optimal charging rate of a charging station battery in the time period is calculated by considering whether the generated power of the new energy meets the charging power of the charging station, and the actual charging rate of the charging station battery in the time period is adjusted to the optimal charging rate in the time period. According to the method, the charging station battery charges the electric vehicle at the optimal charging rate, the maximum new energy consumption rate, the minimum power purchased from the power grid and the minimum influence on the electric power system are achieved, and therefore charging control can be conducted on the electric vehicle charging station in the scene of new energy grid-connected operation, and stable operation of the electric power system is guaranteed.

    本发明公开了一种适合新能源并网的电动汽车充电站的充电控制方法及装置。本发明通过将一日划分为多个时段,对于每一时段,考虑新能源的发电功率是否满足充电站的充电功率来计算充电站电池在该时段最优的充电速率,将充电站电池在该时段的实际充电速率调整为其在该时段最优的充电速率,使充电站电池以最优的充电速率进行电动汽车充电,达到新能源消纳率最大,从电网购电功率最小,对电力系统产生的影响最小,从而能够在新能源并网运行的场景下,对电动汽车充电站进行充电控制,保证电力系统的稳定运行。
