摘要
在实现“双碳”目标的过程中,电动汽车的规模不断增大,其充放电对电网运行产生显著影响。考虑当前对单一电动汽车调度造成的控制指令下发数量较大的问题,分别从电动汽车侧与配电网侧2个角度,提出可调度能力评估指数与效益评估指数。构建电动汽车综合可调度潜力评估模型,对电动汽车群体划分优先调度区并下发指令,减少调度电动汽车的次数。为缓解电动汽车区域流动性给模型求解带来的困难,使用了一种以W-GAN以及k-means聚类算法为基础的电动汽车分类方法。以3个削峰填谷算例为基础,分析了4个电动汽车群体的可调度潜力与调度效果。仿真结果表明,所提出的可调度能力评估指数、调度效益评估指数具有一定的合理性,且运用综合可调度潜力评估模型划分优先调度区可在较少调度电动汽车的情况下完成较好的削峰填谷效果。
The number of electric vehicles is mounting in the process of achieving"dual carbon"target.And their charging and discharging behaviours significantly impact the operation of power grid.In response to the numerous control instructions given to schedule every single electric vehicle(EV),considering from EV side and distribution network side,a dispatchable capacity assessment index and a benefit assessment index are proposed.And a comprehensive dispatchable potential assessment model for EVs is established.Then,EVs can be divided into different groups and those in dispatch priority zones will be given schedule instructions preferentially.To alleviate the difficulty brought by EV mobility between regions to the model solving,an EV grouping method based on W-GAN and k-means clustering algorithm is used.Based on three peak load regulation cases,the dispatchable potential and dispatch performance of four EV groups are analysed.The simulation results show that the dispatchable capacity assessment index and the dispatching benefit assessment index of the proposed method are reasonable.Giving scheduling priority to the divided EV dispatch priority zones selected by the integrated dispatchable potential assessment model can accomplish peak load regulation with less dispatching times.
