Abstract

In order to improve energy utilization and reduce carbon emissions, this paper presents a integrated energy system economic operation strategy of incineration power plant power-to-gas （P2G） with waste heat recovery. Firstly, consider the coordinated operation of Incineration power plant-P2G, introduce the refined Power-to-gas two-stage operation process, add hydrogen fuel cells on the basis of traditional power-to-gas to reduce the energy ladder loss, and recycle the methanation reaction heat. Secondly, in order to improve the energy utilization efficiency of incineration, it is considered to install a waste heat recovery device containing a water source heat pump to recover the waste heat of flue gas and consume some electric energy, sourced from wind power, and add the CO₂ separation device to combine the recovered CO₂ with P2G to synthesize CH₄ to achieve carbon recycling. Finally, within the framework of a tiered carbon trading mechanism an IES optimization model for electricity-heat with the goal of minimizing the system operating cost is constructed, and the GUROBI modeling optimization engine is used to solve this model. The results verify the effectiveness of the model.
