摘　　要：为推动氢能多元生产和利用,提出一种计及沼气重整制氢和燃气掺氢的综合能源系统优化调度模型.首先,构建沼气重整制氢模型,满足天然气负荷的同时,实现生物天然气制氢.其次,将电解水和沼气重整产生的氢气联合,探究沼气重整制氢对系统经济性、低碳性的影响.然后,生成的氢气供给氢燃料电池、掺氢燃气轮机,并引入阶梯碳交易机制,限制系统碳排放.最后,以日运行总成本最低为目标函数,设置4种不同场景进行仿真分析.仿真结果表明:所提模型总成本降低5.33%,碳排放量降低5.17%;合适的秸秆价格有利于消纳风光和利用生物质能;燃气轮机适度掺氢燃烧可以进一步降低总成本和碳排放量.In order to promote the diversified production and utilization of hydrogen energy,an optimal scheduling model of integrated energy system considering biogas reforming hydrogen production and gas hydrogen doping is proposed.Firstly,a model of biogas reforming hydrogen production is constructed to meet the natural gas load while the hydrogen production from biogas is achieved.Secondly,the electrolyzed water and the hydrogen produced by biogas reforming are combined to explore the impact of hydrogen production from biogas reforming on the economy and low-carbon nature of the system.Then,the generated hydrogen is supplied to hydrogen fuel cells and hydrogen-doped gas turbines,and a ladder carbon trading mechanism is introduced to limit the carbon emissions of the system.Finally,the lowest daily operating total cost is taken as the objective function,and four different scenarios are set for the simulation analysis.The results show that the total cost of the proposed model is reduced by 5.33%and the carbon emissions are reduced by 5.17%;the appropriate straw price is conducive to the consumption of wind and solar power and the utilization of biomass energy;and the moderate hydrogen blending combustion of gas turbines can further reduce the total cost and carbon emissions.
