计及用户电池损耗的电动汽车分布式两阶段调度策略
Distributed two-stage scheduling strategy of EV considering user battery consumption
The disorderly charging behavior of large-scale electric vehicles (EV) puts pressure on the power grid. Therefore, the orderly dispatching strategy of EV is of great significance to ensure the safe operation of the power grid. To this end, a distributed two-stage scheduling strategy that takes into account user battery consumption is proposed. First, qualitatively analyze the dispatch willingness and dispatch ability before dispatching to screen for dispatchable vehicles. Secondly, in the first stage, the average charging rate index is proposed, combined with the minimum charging cost to improve user-side optimization, and in the second stage, the minimum peak-valley difference is the goal Peak shaving and valley filling are performed on the grid side. Finally, comparing different scenarios, it is found that the proposed strategy effectively reduces the charging cost and battery loss, reduces the load peak-to-valley difference, smoothes load fluctuations, and takes into account the interests and needs of both the power grid and EV users..
