Abstract: In order to solve the multi-agent conflict of interest in the integrated energy system (IES) and realize low-carbon operation at the same time, a multi-agent low-carbon economic operation strategy of the IES based on double-layer master-slave game was proposed. First, in order to reduce system carbon emissions, ladder carbon trading and comprehensive demand response are introduced to limit carbon emissions. Secondly, the basic framework of the IES with energy storage configured by the energy system operator (ESO) was designed to improve the regulation ability and income level of the ESO. Then, on the premise of fully considering the initiative and decision-making ability of various stakeholders, a multi-agent low-carbon economy operation interaction mechanism based on bi-level master-slave game was established. Among them, the upper level game takes the power producer as the leader and the ESO as the follower; The lower level game takes the ESO as the leader and the energy producer and load aggregator as the followers. Finally, the simulation results show that the proposed strategy can give full play to the active decision-making ability of each subject, promote the balance of interests of each subject, and realize the low-carbon and economic operation of the system.
