Optimized Dispatch of Comprehensive Energy in Park Considering CCS-P2G Coupling and Multi-dimensional Flexibility Resources

In response to challenges such as the difficulty of integrating new energy sources and high carbon emissions in industrial park energy systems, a low-carbon optimization dispatch model based on Carbon Capture and Storage (CCS)-Power to Gas (P2G) coupling and multi-dimensional flexibility resources is proposed. Firstly, a CCS-P2G coupling operation model is established based on the low-carbon mechanism of carbon capture and the two-stage conversion of electricity to gas. Secondly, by considering the coordinated cooperation of CCS-P2G on the supply side, comprehensive demand response, and various types of energy storage resources in the park, the low-carbon operational potential of the park’s multi-dimensional flexibility resources is fully explored. Finally, a tiered carbon trading mechanism is introduced, aiming at minimizing comprehensive operational costs, to construct a low-carbon optimization dispatch model for the park. Through case study simulations, it is demonstrated that the proposed model can enhance the park’s capacity for integrating new energy sources, reduce carbon emissions, and yield significant low-carbon economic benefits.
