基于主从博弈理论的综合能源系统优化运行方法

综合能源系统作为实现智慧能源的关键技术形式,其优化运行问题是一门重要课题。针对综合能源系统优化运行问题,考虑到系统多能互补协调,基于主从博弈理论进行建模。其中:主体博弈模型以多能互补协调计划为博弈策略,以综合能源系统综合运行成本最小化为博弈支付,计及多能互补协调约束等必要约束条件;从体博弈模型以各个形式能源子网的运行计划为博弈策略,以能源子网运行收益最大化为博弈支付,计及分布式供能设备运行约束等必要约束条件。分析得到主从博弈模型的纳什均衡,基于混沌粒子群算法设计模型求解流程。最后通过仿真算法表明,所建立的模型适用于综合能源系统优化运行方案制定,能够显著降低系统运行成本。

Optimal operation method of comprehensive energy system based on master-slave game theory

As the key technology form of realizing intelligent energy,the optimization operation of integrated energy system has been an important topic.For the optimal operation of the integrated energy system,the model was based on the master-slave game theory.Among them,the main body game model takes the multi energy complementary coordination plan as the game strategy,the comprehensive operation cost minimization of the comprehensive energy system as the game payment,taking into account the necessary constraints such as the multi energy complementary coordination constraints;the subordinate game model takes the operation plans of various forms of energy subnets as the game strategy,and the operation revenue maximization of energy subnets as the game payment,taking into account the distributed energy supply design necessary constraints such as standby operation constraints.The Nash equilibrium of master-slave game model is obtained,and the model solving process is designed based on chaos particle swarm optimization algorithm.Finally,the simulation algorithm shows that the model is suitable for the formulation of the optimal operation scheme of the comprehensive energy system,and can significantly reduce the operation cost of the system.
