电动汽车参与电网调峰的模型及调度策略研究

Model of electric vehicle participating power grid peak shaving and scheduling strategy

"汽车-电网"互联(Vehicle to grid简称V2G)技术体现了电动汽车与电网的互动关系,随着电动汽车数量的快速增加和充放电技术的成熟,电动汽车必将成为智能电网的重要组成部分,并有望参与电网调峰平抑负荷波动。建立了一种电动汽车参与电网调峰的模型,提出了基于粒子群算法的调度策略。基于某地区典型的日负荷曲线,研究了电动汽车对电网调峰的影响。

The technology of V2G （vehicle to grid, for short V2G） reflects the interactive relationship between power grid and electric vehicles. With the rapidly increasing number of electric vehicles and mature of charge-discharge technology, electric vehicles will become an important part of smart grid and could be used to restrain load fluctuation. A model of electric vehicle involved in the power grid peak shaving was set up, and a scheduling strategy was proposed based on particle swarm optimization （PSO） algorithm. Based on typical daily load curve in a given area, the influences of electric vehicles Darticipating the Dower Qrid Peak shavina were studied.
