摘要
文章提出了一种计及用户满意度的电动汽车动态分时充电电价制定策略。该策略对用户出行规律进行分析以构建电动汽车并网场景,并预测其可控容量;其次提出基于微电网调度需求的定价策略,实现了价格信号引导的电动汽车充电负荷优化控制;通过仿真获得该策略下的动态电价,并基于该电价探讨电动汽车参与电力系统调度效果。最终验证了所提策略能够削峰填谷,提高可再生能源利用率,有效缓解电网源-荷难以协调的问题。
A dynamic time-of-use pricing strategy for electric vehicle charging considering user satisfaction degree is proposed in this paper.Firstly,this paper researches the travel patterns of electric vehicles to establish the grid connection scenes and predict the controllable capacity of electric vehicles.Secondly,the paper raises a pricing strategy on account of the dispatching requirements of the micro-grid,and realizes the effective dispatch of electric vehicle charging load based on price signals.Furthermore,we gain the dynamic time-of-use charging price,using the strategy proposed above,and the effect of electric vehicles participating in dispatch is discussed based on the price.It is finally verified that the strategy proposed can achieve the goal of peak-load shifting,improve the utilization rate of renewable energy and effectively alleviate the problem of source-load coordination of the grid.
