V2G模式下电动汽车平抑负荷波动的优化策略

Optimization Strategy for Restraining Load Fluctuation by Electric Vehicle in V2G Mode

在V2G(VehicleTo Grid)模式下,电动汽车与电网能够实现功率的双向流动。当电动汽车大规模应用时,可以利用其充放电功能,平抑电网的负荷波动。在电动汽车规模化应用的前提下,对电动汽车进行分类,将私有类电动汽车作为研究目标,建立其1天内的功率模型,提出了基于改进粒子群算法的电动汽车优化调度策略,能有效抑制电网的负荷波动。

The power flowing in both directions between electric vehicle and power grid can be realized in V2G mode. The charge and discharge function could be used to restrains load fluctuation when the electric vehicle is put into large scale application. In the premise of electric vehicle＇s large scale application, the electric vehicle is classified, and the private electric vehicle is made to be the research target. Then the corresponding power model in one day is established, and the optimized scheduling strategy based on modified PSO is proposed. Using the strategy, the load fluctuation is restrained obviously.
