基于主从博弈的燃气-太阳能-地热能耦合系统运行优化

OPTIMAL OPERATION OF COUPLED GAS-SOLAR-GEOTHERMAL ENERGY SYSTEM BASED ON STACKELBERG GAME

为提高能源利用率与经济性,提出一种基于博弈论中主从博弈的燃气-太阳能-地热能集成综合能源系统优化运行策略。首先建立综合能源系统模型,将其嵌套入博弈理论的框架下,建立主从博弈的运行优化模型,将能源聚合商作为领导者,综合能源系统和负荷终端用户作为跟随者,在各方追逐目标最优时实现经济性、环保性和节约性。最后通过算例验证了所提方法的有效性,聚合商、供能系统和终端用户均能实现最优的综合性能。

In order to improve the energy utilization and economy,this paper proposed a gas-solar-geothermal integrated energy system optimization operation strategy based on Stackelberg game.The integrated energy system is first modeled.Then,we nest it is nested into the framework of game theory and build the operation optimization model of Stackelberg game.The energy aggregator is considered as the leader while the integrated energy system and users as the followers.Economy,environmental protection and conservation are achieved when each party pursues the optimal goal.Finally,the effectiveness of the proposed method is verified by arithmetic examples,where the aggregator,the energy supply system and the end-user are able to achieve the optimal integrated performance.
