摘要
随着越来越多的电动汽车接入电网,电动汽车充电将对输电网和配电网的调度运行产生重大挑战。综述了电动汽车充电负荷建模、影响评估方法、电动汽车参与配电网层面和输电网层面优化调度的研究现状,包括分布式充电方法、电动汽车与微电网的相关研究、电动汽车和风电协同调度研究等。结论表明:若能通过分布式优化调度算法有效地处理电动汽车在电网上充电或放电的问题,就有希望将电动汽车充电带来的挑战转化为机遇,实现电网更理想的削峰填谷和促进电网对风能、太阳能等新能源的消纳。
With more and more electric vehicles（EVs） integrated into power grids,the charging of EVs may impose great challenges on dispatching and operating of both transmission and distribution grids.A literature review on the impact of EVs charging on both transmission and distribution grids as well as optimal dispatch study is presented in this paper,which includes distributed smart charging,EVs and microgrids coordination,EVs and large-scale wind energy coordination,and so on.It is concluded that if the issue of EVs charging and even discharging behaviors can be effectively dealed with through smart distribution dispatching algorithm,the challenge of EVs charging may create a new opportunity for power grids to solve the problelm of peak load shifting and improve the utilization of new energies shch as wind energy and solar energy.
