Dynamic Pricing and Energy Management of Electric Heating Integrated Energy System Based on Master-Slave Game Theory

The shift in the energy market from the conventional vertically integrated model to a modern, highly efficient, clean, and low-carbon power system structure makes it challenging for the traditional centralized optimization approach to elucidate the interactions among multiple agents. In this paper, a dynamic pricing problem of electrothermal integrated energy system based on master-slave game is proposed, which takes the overall income of the integrated energy system as the objective function and the follower as the objective function Drawing from the principles of the master-slave game. solve the strategic solution of all parties when the objective function is optimal. First of all, this paper introduces the transaction mode of the park System for energy integration. and the mathematical model of each combination in the system, and establishes a master-slave game model framework through the mathematical theory and method of game theory. Secondly, the existence and uniqueness of Stackelberg equilibrium are proved and solved by differential evolution algorithm and CPLEX solver. Finally, a numerical example is given to verify the effectiveness of the proposed method.
