摘　　要：随着新能源装机规模不断扩大,传统碳捕集热电厂因承担供热任务而存在碳捕集效率低、调节能力不足的现象。为了促进新能源消纳和减少碳排放,同时提升热电厂的调峰能力,构建一种氢储能与富氧燃烧碳捕集机组联合运行模型,并进行低碳经济优化调度。首先,分析富氧燃烧碳捕集与氢储能协调运行机理,并构建系统架构;其次,计及空分制氧与氢储能氧气回收,分别建立富氧燃烧碳捕集机组与氢储能系统模型;最后,通过碳交易和调峰辅助服务市场提升电厂降碳、调峰主动性,以系统运行成本最优为目标,建立考虑氢储能的富氧燃烧碳捕集电厂优化调度模型。算例结果表明,所提模型不但可以有效提高系统低碳性与经济性,还可以提升热电厂的调节能力,促进新能源消纳。As renewable energy installation scales up,traditional carbon capture combined heat and power plants face challenges such as low carbon capture efficiency and inadequate regulatory capacity due to their heating supply obligations.In order to promote renewable energy integration and reduce carbon emissions while enhancing the peak regulation capabilities of these plants,this study constructs a joint operational model integrating hydrogen energy storage with oxy-fuel combustion carbon capture units,focusing on low-carbon economic dispatch.The paper first investigates the coordination mechanisms of oxy-fuel combustion carbon capture and hydrogen energy storage,establishing a system architecture.It then considers oxygen production from air separation and oxygen recovery from hydrogen storage,developing separate models for oxy-fuel combustion carbon capture units and hydrogen energy storage systems.Finally,leveraging carbon trading and peak regulation auxiliary service markets to enhance carbon reduction and peak regulation initiatives of power plants,the study aims to optimize system operating costs,establishing a low-carbon economic dispatch model for oxy-fuel combustion carbon capture plants integrated with hydrogen energy storage.Case study results demonstrate that the proposed model not only effectively improves system carbon efficiency and economic performance but also enhances the regulatory capabilities of combined heat and power plants,facilitating renewable energy integration.
