Optimal Scheduling of Integrated Energy System Considering Biogas Reforming Hydrogen Production and Gas Hydrogen Doping
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.
