|
摘要
为了实现电动汽车的充电快速性同时兼顾电网侧配电容量,提出了一种基于直流母线的双向充放电系统方案。解决了大功率快速充电需求对于电网配电容量的增容问题,同时又实现了电网负荷峰谷调节目的。搭建了仿真模型,仿真结果验证了所提方案的有效性,同时提升电网运行经济性。
In order to realize the rapid charging of electric vehicles and also take account of the power distribution capacity of the grid at the same time,this paper proposed a scheme of bidirectional charging and discharging system based on DC bus,which solves the capacity expansion problem of power distribution capacity for high power fast charging demand,and also achieved the purpose of adjusting the peak and valley of the power grid load. The simulation model was built,the simulation results verify the effectiveness of the scheme which could also improve the economy of grid operation.
