摘　　要：在“双碳”目标下,使用新能源、提高能源使用效率、减少二氧化碳排放等都是综合能源系统需要考虑的重要因素。针对常见氢能多元利用模型中能量转换效率不高、系统降碳手段没有充分考虑的问题,提出一种考虑高效氢能利用和碳捕集的综合能源系统低碳优化调度模型。首先,在常见氢能多元利用模型的基础之上,构建高效氢能利用模型。通过建立电解槽的供热模型以及甲烷反应器的热回收模型,提高综合能源系统在应用氢能时的能量转换效率,实现系统的低碳经济运行。然后,在设备层面引入碳捕集装置和碳封存装置,在机制层面引入阶梯式碳交易机制,从多方面进一步实现综合能源系统碳排放量的降低。最后,设置算例进行分析,通过对比不同场景证明了所提出模型的高效性和低碳性。The utilization of new energy,improvements in energy efficiency,and reductions in carbon emissions are important factors that must be considered in integrated energy systems.In response to the issues of low energy conversion efficiency and insufficient consideration of decarbonization methods in multifunctional hydrogen utilization,this study proposes a low-carbon economic dispatch model for an integrated energy system considering efficient hydrogen utilization and carbon capture equipment.First,an efficient hydrogen-utilization model was constructed based on a common model of multifunctional hydrogen utilization.A heating model for the electrolyzer and a heat recovery model for the methane reactor were constructed to improve the energy conversion efficiency of hydrogen utilization and achieve low-carbon economic operation of the system.Second,carbon capture and storage equipment are introduced at the equipment level,whereas a ladder-type carbon trading mechanism is implemented at the institutional level to further reduce the carbon emissions of the integrated system from multiple perspectives.Finally,case studies are established for analysis,demonstrating the efficiency and low carbon emissions of the proposed model through comparisons of different scenarios.
