Electric-hydrogen-gas integrated energy system considering E2H conversion process and comprehensive demand response coordination and optimization of operation

With the development of integrated energy system research,the requirement of power to gas(P2G)process research is getting higher and higher.Simply regarding electro-conversion gas as electro-conversion natural gas ignores the great potential of hydrogen as an intermediate product.Therefore,this paper comprehensively considers the process of converting electricity to hydrogen and hydrogen to natural gas,and builds an integrated energy system of electricity,hydrogen and gas based on this.By considering the demand side response,a multi-objective coordinated optimization model is established with the objective function of minimizing the total operating cost and minimizing the environmental cost of the system.The results show that the coordinated optimization method combined with the integrated demand response strategy enhances the economy,environmental protection and new energy consumption capacity of the integrated energy system based on the consideration of the electro-hydrogen conversion process.
