基于博弈论的入网电动汽车最优经济调度优化

Optimal economic dispatch for the plug-in electric vehicle based on game theory

入网电动汽车(plug-in electric vehicle,PEV)的大规模接入,对电网的规划和运行带来不可忽略的影响,给系统运行提出挑战。电动汽车入网(vehicle-to-grid)描述的是一种未来电网技术,电动汽车不仅作为电力消费体,同时也能在不使用的时候为电网提供电力。本文应用博弈论对电动汽车用户在一天当中的充放电量进行优化,通过算例分析验证有序充放电策略能够使电动汽车用户获得收益,此外,该方法还能够达到平抑负荷的目的。

Large-scale integration of plug-in electric vehicle（ PEV） brought an influence on power network＇s planning and operation which cannot be neglected and a challenge on power system operation. V2G（ vehicle-to-grid） was a future technology for power system,in which electric vehicles were,besides power consumers,able to support the grid as an energy storage when not used. In this essay the game theory was applied to optimize the daily charge and discharge capacity of plug-in electric vehicle users. An example was proposed and the profit of users was verified deploying this strategy. Besides,the results also showed its capability to stabilize the practicability of load.
