Abstract: Against the background of the “30 × 60” target, low-carbon policies and technologies have become the new starting point and destination of energy conservation and emission reduction in energy systems. Power-to-Gas (P2G), as a new energy conversion mode, provides a new way of consuming energy and reducing carbon emissions. An optimal dispatching model of a park-level integrated energy system considering flexible load and power-to-gas (P2G) participation in the carbon trading market is proposed. Firstly, a comprehensive demand response model for electricity and heat is established according to the system’s flexible load characteristics, adding power-to gas equipment and a combined heat and power (CHP) unit to the system. Secondly, against the background of the carbon trading mechanism and considering the incentive effect of P2G on the carbon trading mechanism, a systematic comprehensive carbon trading cost model is established. Finally, the operation objectives of the low-carbon economy, with minimum energy purchase costs, carbon emission costs, and operating costs, are constructed using a CPLEX commercial solver. The results verify the importance of considering the operational cost of P2G and the feasibility of considering both operating economy and wind power accommodation ability together in integrated energy systems.
