Low-carbon economic dispatching method for integrated energy system containing P2G and energy storage

The invention discloses a low-carbon economic dispatching method for an integrated energy system containing P2G and energy storage, and the method comprises the steps: introducing a power-to-gas equipment operation mechanism and a carbon transaction mechanism into an integrated energy system model of a multi-energy coupling unit, so as to reduce the operation cost of the integrated energy system. The method comprises the following steps: firstly, comprehensively considering the characteristics of each unit in an integrated energy system, constructing a regional integrated energy system joint scheduling structure comprising power-to-gas equipment P2G, energy source equipment, storage equipment and conversion equipment, analyzing the working mechanism of the power-to-gas equipment P2G, and establishing a carbon transaction model of the power-to-gas equipment P2G; secondly, establishing an integrated energy system optimization operation model considering the carbon transaction cost by taking system operation pro
