Abstract: Integrated energy system is an energy supply method that enables the complementary and efficient utilization of multiple energy sources. However, integrated energy system involves multiple stakeholders, including the integrated energy operator, energy storage system, and energy user. Their behaviors can lead to reduced system benefits, increased carbon emissions, and even violations. To address the above issues, an integrated energy system hybrid game model with the participation of the regulatory agency is constructed, and a divide-and-conquer algorithm is proposed to solve it. Firstly, this study establishes a Stackelberg game model to analyze the interactions among participants within the system and formulates a non-cooperative game model to investigate the relationship between integrated energy system and regulatory agency. Then, game theory is combined with the divide-and-conquer algorithm to solve the hybrid game model, evaluating the optimal strategies for the integrated energy operator as the leader, the energy storage system and energy user as followers under regulatory agency's interventions. Finally, a case study is conducted to analyze the regulatory agency's goal of maximizing overall system benefits and environmental benefits. By analyzing the impacts of various regulatory strategies on the system, this study provides actionable decision support and policy recommendations for the regulatory agency.
