Multi-energy Complementary Integrated Energy System Electricity-heat-gas Collaborative Dispatch Considering Games Theory

Multi-energy complementary integrated energy system (MCIES) serves as a pivotal strategy for enhancing energy utilization efficiency, fostering sustainable energy development, promoting green and low-carbon transformation, and achieving the ambitious "double carbon" goal. Considering the mechanism of carbon emission trading (CET), a coordinated low-carbon optimal scheduling model for electric-heat-gas systems in MCIES is introduced, drawing inspiration from a Stackelberg game framework. The strategic interactions among the players as they strive to maximize their individual profits are analyzed in this model where the integrated energy system operator (IESO) was assumed as the leader, while the energy supplier (ES) was assumed as the follower. This paper first introduces the mathematical model and game framework of MCIES, and then uses GA-MILP algorithm to solve the problem. Finally, the proposed method's effectiveness has been confirmed through a case study.
