基于博弈论的多能互补综合能源系统规划设计方法

基于博弈论构建由热电联产机组、光伏发电和电网组成的多能互补综合能源系统优化规划模型.模型以经济性为优化目标,各参与者容量为决策变量,使系统既能满足用户对冷、热、电负荷的需求,又能同时实现收益最大化.根据参与者是否结盟,提出5种博弈模式,证明Nash均衡的存在性,并通过仿真算例得到各模式下的Nash均衡策略.仿真结果表明,在满足负荷需求的同时,与非合作博弈相比,4种合作博弈联盟价值均大于0,且完全合作博弈模式下系统总收益最高.可见,只有通过采取完全合作的最优策略才能保证系统经济效益最大化.

Planning and design method of multi-energy complementary energy system based on game theory

Based on the game theory, this paper develops a planning model for the multi-energy complementary integrated energy system, which is composed of cogeneration unit, photovoltaic unit and utility grid. The model takes the economy as the optimization goal, and the capacity of each participant as the decision variable, so that the system can meet the cooling, heating, and electrical loads of users and maximize the revenue at the same time. According to the alliance of participants, five game models are proposed to prove the existence of Nash equilibrium, and the Nash equilibrium strategies in each mode are obtained through simulation. The simulation results show that, while meeting the load demands, compared with non-cooperative game, the values of four cooperative game alliances are greater than zero, and the total system revenue is the highest under the fully cooperative game mode.
