Design Method of Multi energy Complementary Comprehensive Energy System for Industrial Parks Based on Game Theory

Construct a multi-energy complementary integrated energy system optimization planning model based on game theory, which is composed of cogeneration units, photovoltaic power generation and power grids. The model takes economy as the main optimization goal, and the capacity of participants is called a decision variable. The system can not only solve the user's demand for cooling, heating and electricity, but also maximize the profit of the model. According to whether the participants form an alliance, five game modes are proposed to prove the Nash equilibrium, and the Nash equilibrium strategy in each mode is obtained through simulation experiments. The simulation results show that, compared with non-cooperative games, the value of the four cooperative games is greater than zero, and the total profit rate of the system under the fully cooperative game mode is the largest. It can be seen that only by adopting a fully cooperative optimal strategy can the system's economic benefits be maximized.
