Optimal Operation of Integrated Energy System in Park Considering Hydrogen Blending Gas and Integrated Demand Response

Aiming at the characteristics of low energy conversion efficiency and low utilization rate of hydrogen energy in the integrated energy system of industrial parks, an integrated energy system architecture of industrial parks with hydrogen blending gas and integrated demand response is proposed. Firstly, the mathematical models of hydrogen-doped gas turbine, hydrogen-doped gas boiler and hydrogen production from natural gas are established. Secondly, an integrated demand response model is established based on various energy characteristics of electricity, heat, gas and hydrogen. Finally, an objective function is established to minimize the operating cost of the system. According to the fact example, this paper analyses the influence of the effects of different fixed, variable hydrogen doping ratios and the load characteristics of the park after demand response on system low carbon and economy.
