The invention belongs to the technical field of vehicle network integration, and particularly relates to a charging scheduling method and system for electric vehicles, and the method comprises the steps: obtaining the shortest path of each electric vehicle from a starting point to a terminal point through each photovoltaic charging station; calculating the energy cost, the time cost and the charging cost of each shortest path; determining an optimal path and travel cost of each electric vehicle; calculating the total electric vehicle charging power of each photovoltaic charging station at each moment; calculating the charging and discharging power of an energy storage battery of each photovoltaic charging station at each moment; obtaining the optimal electricity price of each photovoltaic charging station at each moment; and performing charging scheduling according to the optimal electricity price and the optimal path. According to the method, the charging and discharging power of each energy storage battery is obtained by obtaining the optimal path and the stroke cost of each electric vehicle, the target function is obtained and solved by combining the stroke cost and the charging and discharging power of the energy storage batteries so as to minimize the total cost of all the electric vehicles, and it is ensured that the charging and discharging power of each energy storage battery is lower than the preset threshold value.

    本发明属于车网融合技术领域,具体涉及一种用于电动汽车的充电调度方法与系统,所述方法包括:获取每辆电动汽车从起点经过每个光伏充电站到终点的最短路径;计算各最短路径的能量成本、时间成本和充电成本;确定每辆电动汽车的最佳路径及行程成本;计算每个光伏充电站每个时刻的电动汽车充电总功率;计算每个光伏充电站每个时刻储能电池的充放电功率;获取每个光伏充电站每个时刻的最优电价;根据最优电价及最佳路径进行充电调度。本发明通过获取每辆电动汽车最佳路径及行程成本得到每个储能电池的充放电功率,结合行程成本和储能电池的充放电功率得到并求解目标函数以最小化所有电动汽车的总成本,并确保每个储能电池的充放电功率低于预设阈值。
