摘　　要：在“双碳”背景下,如何通过政策与技术手段来实现节能减排,已成为当前研究的新热点。为解决燃烧后碳捕集电厂在发电过程中碳捕集率低和成本高等问题,提出了考虑富氧燃烧技术的综合能源系统优化调度模型。首先,建立了电气热综合能源系统模型,将燃气电厂低碳化改造为富氧燃烧电厂,并搭建了富氧燃烧-风电-光伏联合运行框架,达到三者共同分担碳捕集运行能耗的效果;其次,在此基础上,将系统总运行成本最小作为目标函数,构建了综合能源系统优化调度模型;最后,设置4种不同的场景进行算例分析。算例结果证明了所提模型的可行性,在综合能源系统中引入富氧燃烧技术能有效降低系统的碳排放,并使系统的经济性能得到很好的改善。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 oxyfuel combustion technology into the integrated energy system can effectively reduce carbon emissions and improve the economic performance of the system.
