Research on Stackelberg Game Optimization Dispatch of Metamodel of Integrated Energy System Considering Carbon Capture and P2G

In order to promote the complementarity and low carbonization of various energy sources and take into account the interests of both market operators (MO) and integrated energy system (IES), a Stackelberg game model of IES including carbon capture system (CCS) and carbon trading is proposed. The cooperative operation framework of carbon capture, power-to-gas (P2G) and combined heat and power (CHP) generation unit is introduced to effectively solve the carbon source required by P2G unit and system carbon emission problems. Considering the coupling characteristics of electricity, heat and gas, a carbon trading mechanism is introduced, and the dynamic pricing mechanism of MO and the optimal scheduling of IES are studied. The Stackelberg game model built in this paper is difficult to be solved by traditional methods, so we introduce a Stackelberg game optimization algorithm based on Kriging meta-model to reduce repeated calls to the underlying model and improve solving efficiency. Through a lot of simulation verification, compared with other traditional models, this model can effectively reduce the carbon emissions and operating costs of the system, and improve the capacity of renewable energy.
