Abstract

For carbon capture and storage （CCS） technology and power-to-gas （P2G） equipment, a joint operation mode of carbon capture, P2G and energy storage equipment is proposed, which improves the utilization efficiency of hydrogen energy by refining the two-stage operation process of P2G. Energy storage equipment is used to solve the time mismatch problem of CO₂ capture and utilization, and the stepped carbon trading mechanism is considered to further reduce CO₂ emissions in the integrated energy system （IES）. Based on this, an IES low-carbon economy optimization scheduling model with carbon capture is constructed, and two scheduling modes are divided according to the carbon emissions at different times. The model is solved using the solver GUROBI software in Matlab software. The simulation results show that the proposed scheduling method further reduces system operating costs, improves renewable energy consumption and reduces carbon emissions.
