Power-to-gas (P2G) technique realizes the two-way coupling for the integrated electricity and natural gas systems, which provides an eff ective way for wind power accommodation based on its operating characteristic. Therefore, a new economic low-carbon clean dispatching of power system containing the power to gas (P2G) considering the comprehensive infl uence of the multi-price factor is proposed. Firstly, the P2G operation and carbon trading mechanism models are established. Secondly, the goal is to minimize the sum of thermal power generation costs, gas turbine power generation costs, carbon trading cost, wind abandonment penalty cost, and P2G operating costs and taking into account the comprehensive impact of multiple price factors and the security constraints of the natural gas network and the power network. Then, the improved particle swarm optimization algorithm is used to solve the model. Finally, the rationality and eff ectiveness of the proposed model are verifi ed through the analysis of calculation examples, and it is proved that the conversion of electricity to gas can eff ectively improve the wind power absorption capacity of the grid, which provides a reference for the low-carbon dispatch operation of the integrated energy system.
