基于主从博弈的含电动汽车综合能源系统运行策略

综合能源系统(IES)是解决能源生产与分配等问题的重要能源系统之一,考虑电动汽车作为综合能源系统中重要的主动负荷,合理引导其充电能促进综合能源系统的高效运营,提出了综合能源系统与电动汽车的主从博弈优化运行模型。在主从博弈框架下,以综合能源系统为领导者,各电动汽车为跟随者,构成一主多从优化调度模型。根据博弈的阶段性特点,提出基于引力搜索算法和混合整数线性规划的两阶段主从博弈求解方法。算例对比分析表明,通过主从博弈,综合能源系统能合理地引导电动汽车有序充电,有效整合分布式能源并提高了运行的整体经济收益。

Stackelberg Game Based Operational Strategy Research of Integrated Energy System with Electric Vehicles

Integrated energy system (IES) is one of the most important energy systems for energy production and distribution. The electric vehicle (EV) is an important active load in the IES, which contributes to promoting the efficient operation of the IES by leading the EV. An optimization operation model is established for IES and EV based on the Stackelberg game. Under the Stackelberg game framework, a leader multi-followers optimal scheduling model is formed, where IES is regarded as the leader and the electric vehicles are regarded as the followers. Besides, a solving algorithm is proposed combining the gravitational search algorithm and the mixed-integer linear programming method. The comparative analysis of numerical examples shows that IES is capable of leading EV charging orderly, integrating distributed energy resources effectively, and improving the overall economic benefits of operation by the Stackelberg game.
