光储充一体化电站优化配置方法

Optimal Configuration Method for PV-Storage-Charging Integrated Power Station

电动汽车对于推动节能减排具有巨大作用,但大规模电动汽车接入电网后,其充电负荷会给电网带来短时负荷冲击,影响电网安全运行。光储充一体化电站可利用光伏和储能来平衡电动汽车充电负荷,有效降低大规模电动汽车充电对电网资源的占用。针对光储充一体化电站的规划需求,首先建立了光伏模型和基于寿命预测的储能模型,然后以最大化光储充一体化电站的净收益为目标,以设备运行和功率平衡为约束,建立了光储充一体化电站设备优化配置模型,并采用遗传算法进行求解,最后通过算例验证了该方法的有效性。

Electric vehicles play a huge role in promoting energy conservation and emission reduction.However,when large-scale electric vehicles are connected to the grid,the charging load brings a short-term load impact to the grid,which affects the safe operation of the grid.The PV-storage-charging integrated power station utilizes PV and energy storage to balance the charging load of electric vehicles in order to reduce the impact.In view of the planning demand of the integrated charging station,PV and energy storage model based on life prediction is established with the objective to maximize the net income of the station.Based on the constraints of equipment operation and power balance,an optimized configuration model for the integrated station is constructed,and the model is solved by genetic algorithm.Finally,the effectiveness of the method is verified by a study case.
