Abstract

Abstract: Aiming at the environmental protection problem that the CO₂ generated by waste incineration power plants is difficult to deal with, a waste incineration power plant-flue gas treatment-P2G coordinated and optimized operation model based on carbon recycling is constructed in this paper. The electricity-to-gas technology recovers CO₂ and synthesizes methane to realize carbon recycling and reuse. The model aims to maximize the comprehensive net income composed of electricity sales revenue, carbon emission costs, auxiliary fuel purchase costs, flue gas treatment and power-to-gas power operating costs. The operating periods of incineration power generation, flue gas treatment, flue gas collection, flue gas storage, and electricity-to-gas synthesis are the decision variables. The simulation results show that the model uses the real-time electricity price and the flue gas storage device to flexibly coordinate the power generation, flue gas treatment and power to gas operation state of the waste incineration power plant in different periods, which can effectively reduce the cost of auxiliary fuel purchase and carbon emission, increase the income of electricity sales, fully realize the carbon recycling, and have significant economic and social benefits.

Key words: waste incineration power plant, carbon cycle, flue gas treatment, power to gas, coordination and optimization
