ABSTRACT = {Against the backdrop of China’s “dual-carbon” target, clean energy generation currently accounts for about 3.8 trillion kilowatt-hours, or 39.7 percent of total power generation, establishing a reasonable market trading mechanism while enhancing the low-carbon economic benefits of the integrated energy system (IES) and optimizing the interests of various entities within the distribution system has become a significant challenge. Consequently, this paper proposes an optimization strategy for a low-carbon economy within a multi-agent IES that considers carbon capture systems (CCS) and power-to-gas (P2G). In this framework, the integrated energy system operator (IESO) acts as the primary leader, while energy suppliers (ES), energy storage operators (ESO), and load aggregators (LA) follow. At the level of low-carbon technology, a coupling model of P2G and CCS is developed, leading to the establishment of an IES that incorporates energy conversion and storage equipment. Economically, effective control of system carbon emissions in market trading is progressively established. Lastly, the trading decision model of the system is integrated within a master-slave game framework, utilizing an improved differential evolution algorithm in conjunction with the distributed equilibrium method of quadratic programming for solution. The calculation example demonstrates that the strategy safeguards the benefits for both parties in the game and achieves energy savings and carbon reduction for the system.},
