Abstract: On a double carbon goal background, to address the issues of insufficient regulation capacity of conventional carbon capture methods and the lack of further exploitation of the low-carbon potential of power to gas, an integrated energy systems optimal dispatching strategy was proposed with liquid storage carbon capture and power to gas thermal recovery taken into consideration. Firstly, the energy time-shifting characteristics of liquid storage carbon capture units to promote wind power consumption were investigated. The second part involves analyzing the justification for power to gas as an equivalent electrical load, while considering thermal recovery characteristics to enhance wind power consumption capacity. A low carbon economic dispatch model for integrated energy systems was then constructed with the objective of minimizing operating costs. Finally, the proposed model was verified through simulation, demonstrating its economy and low-carbon characteristics in reducing the wind abandonment rate of the system. This serves as a crucial reference for realizing the low carbon transition of power systems.
