在电动汽车快速充电站中配置储能系统,可以起到减少充电站配电容量、减轻快速充电对电网冲击和降低综合费用等作用。基于线性规划建立具有储能系统的充电站综合造价数学模型,采用Lingo优化软件求解最优的充电站配电容量及储能容量,并对充电站扩容、电池梯次利用方面做了分析计算。实例验证这种结合储能技术的建站模式能够节约成本,提高资源利用率。
Configuring the energy storage system in the EV quick charging station can reduce the distribution capacity of the charging station, reduce the impact of rapid charging on the grid and reduce the overall cost. Based on linear programming, a mathematical model of charging station integrated cost with energy storage system is established. The optimal charging station power distribution capacity and energy storage capacity are solved by Lingo optimization software. The charging station expansion and battery echelon utilization are analyzed and calculated. The example verifies that this mode of building station integrating energy storage technology can save costs and improve resource utilization.
