Low Carbon Economic Dispatch of Integrated Energy System with Liquid Storage Carbon Capture Power Storage Considering Integrated Demand Response

Based on the background of "carbon peaking" and "carbon neutrality", this paper proposes a low carbon economic operation strategy for integrated energy system with liquid storage considering demand response in order to improve energy utilization, optimize equipment operation flexibility, and further reduce carbon emission level and operation cost of integrated energy system. In this paper, we propose a low-carbon economic operation strategy for integrated energy systems with liquid storage that takes into account demand response. First, we introduce a carbon capture device with liquid storage in an integrated energy system to flexibly dispose of the CO2 generated from the operation of a thermal power unit. Second, we introduce a demand response policy to guide power users to modify their inherent power consumption patterns and adjust their power demand through an incentive mechanism, thereby modifying the power load curve and reducing the peak-to-valley difference. Finally, a low-carbon economic operational model of an integrated energy system with optimal total system operation cost is constructed, the CPLEX commercial solver is used to solve the constructed model, and the effectiveness of the proposed strategy is compared and validated by setting several operational scenarios.
