Optimal Scheduling of the Integrated Energy System Considering Oxy-Fuel Combustion Technology
In the context of"dual carbon",many researches have now focused on how to achieve energy conservation and emission reduction through policies and technological means.To address the low carbon capture rate and high cost in the power generation process of post combustion carbon capture power plants,an optimization scheduling mode for the integrated energy system considering oxy-fuel combustion technology is proposed.First,a comprehensive energy system model for electrical and thermal energy is established,and a low-carbon gas power plant is transformed into an oxy-fuel combustion power plant.A framework for the joint operation of oxy-fuel combustion,wind power,and photovoltaic is established to achieve the effect of sharing the energy consumption of carbon capture operation among the three.Second,based on this,a comprehensive energy system optimization scheduling model is constructed with minimizing the total operating cost of the system as the objective function.Finally,four different scenarios are set up for numerical analysis.The example results have verified the feasibility of the proposed model.Introducing oxy-fuel combustion technology into the integrated energy system can effectively reduce carbon emissions and improve the economic performance of the system.
