基于供需双侧博弈互动的园区多能运营商能源交易优化决策

Optimal Decision of Energy Trading for Community Multi-energy Operator Based on Game Interaction With Supply and Demand Sides

随着能源市场改革的逐步深入,大量新兴市场主体涌入市场展开激烈竞争。在此背景下,以园区运营商对园区综合能源系统(integrated energy system,IES)进行管理并参与市场为应用场景,建立与供需双侧博弈互动的园区运营商能源交易决策模型。首先,基于Stackelberg博弈理论,同时考虑供给侧和需求侧市场主体的主动性,提出园区运营商供需双侧博弈互动框架。其中,园区运营商分别采用功率-价格曲线和分时统一价格与能源供应商和用户进行互动模拟。然后,采用能源枢纽(energy hub,EH)建模方法,详细构建园区IES调度模型,以园区运营商净利润最大化进行园区IES运行优化。接着,证明该博弈互动模型纳什均衡(nash equilibrium,NE)的存在性和唯一性,并提出相应的NE求解流程。仿真结果表明,所提博弈互动模型的求解具有良好的收敛性,园区运营商与供需双侧进行博弈互动可更好地调整自身分布式能源设备的运行,并以更低的成本进行购能。

With the gradual development of energy market reform,a large number of new market players entered the market to launch fierce competition.In this background,taking the integrated energy system(IES)management and market participation of the community operator as the application scenario,the community operators’energy trading decision-making model based on the game interaction with supply and demand sides was proposed.First,based on the Stackelberg game theory,considering the initiative of market players of supply and demand sides,a game framework of the community operator interact with supply and demand sides was proposed.In addition,the community operator used the power-price curve and time-of-use unified price to interact with the energy suppliers and users.Then,based on the energy hub(EH)modeling method,the IES optimization model was constructed to optimize the operation of the community to maximize the total profit of the community operator.Then,the existence and uniqueness of the Nash equilibrium(NE)of the game model were proved,and the corresponding solution process was proposed.The simulation results show that the solution of the game interaction model has good convergence,and the community operator can adjust the operation of their own distributed energy equipment better and purchase energy at a lower cost by the game interaction with market players of supply and demand sides.
