Abstract: 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.
