Low-Carbon Economic Dispatch of Coal Mine Integrated Energy System Considering Associated Energy Sources and CCS-P2G Coupling

Under the background of the "double carbon" goal, in order to realize carbon emissions reduction of energy systems and improve the energy utilization efficiency of the mining area, the paper proposes a low carbon economic scheduling model for coal mine integrated energy system (CMIES) considering associated energy resources and CCS-P2G coupling. First, the basic model of CMIES is established, and carbon capture and storage (CCS), power-to-gas (P2G) are used as a coupling unit to promote energy conservation and emission reduction and renewable energy consumption. Secondly, the reward and punishment ladder-type carbon trading mechanism are introduced, and a optimization scheduling model for CMIES is established to minimize the operating cost of by comprehensively considering the economy of the system and the low-carbon nature of the system. Finally, by setting up different scenarios for simulation analysis, the results show that the proposed model can promote the low-carbon and economic operation of CMIES.
