In order to realize the coupled utilization and low carbonization of integrated energy systems (IES) in the context of the "double carbon" target

this paper proposes an advanced adiabatic compressed air energy storage (AA-CAES) plant with a solar thermal module and a power-to-gas (P2G) and liquid carbon capture system (CCS) for the low carbon optimal scheduling model of IES. In this paper

we establish the coupling model of solar thermal module and AA-CAES power plant and introduce it into the IES with P2G-CCS. The operation strategy of the combined wind-light-carbon capture power plant with carbon capture equipment and carbon trading model are proposed. The IES low-carbon optimal scheduling model is constructed with net carbon emission and comprehensive cost minimization as the objective function. It is verified that the synergistic operation of AA-CAES energy storage plant containing solar thermal module and P2G-CCS can further reduce the total cost and carbon emission through arithmetic comparison.
