In the context of dual carbon

technologies such as Carbon Capture and Storage （CCS）and Power-to-Gas（P2G）are the key to realizing low-carbon economic operation of the Integrated Energy System （IES）。important means.In order to take into account the low-carbonization and economic benefits of IES

this paper proposes a low-carbon IES optimal dispatch model including CCS-P2G.First

at the technical level

IES combines a carbon capture power plant with a solution storage and a two-stage power-to-gas device

and analyzes the linear relationship between carbon dioxide mass and solution volume and CCS operating energy consumption and total output to further simplify the CCS model.At the same time

the conventional hydrogen storage tank model is improved

reducing the computational burden required.Secondly

at the market mechanism level

the paper introduces a carbon trading mechanism and a wind power trading mechanism.Finally

an optimal scheduling strategy based on minimizing the total operating cost of IES as the objective function is proposed.Different scenarios were set up for comparative analysis to verify the effectiveness of the scheduling plan.
