Under the requirements of achieving carbon peak and carbon neutralization in China, the development of hydrogen energy industry has become an important goal of China's future development because hydrogen energy has the characteristics of zero carbon emission and high calorific value. In order to solve the characteristics of low energy conversion efficiency, small amount of hydrogen production and low economic benefit of the comprehensive energy system of the industrial park for hydrogen production and energy storage by electrolytic water, as well as the national need for the development of large-scale and low-cost hydrogen production by hydrogen energy, a PIES (Park-level Intergrated Energy System) of the hydrogen storage park with natural gas hydrogen production mode instead of electrolytic cell hydrogen production is proposed. Based on the analysis of energy consumption and energy recovery of hydrogen production unit by steam reforming of natural gas and various energy characteristics of electricity, heat and gas of hydrogen energy storage unit, a hydrogen energy storage model for hydrogen production and energy storage of natural gas is established; Further considering the equipment investment cost, operation cost, carbon emission price and hydrogen production benefit, the objective function is established with the minimum annual investment cost and the maximum annual operation benefit as the objective, which is solved by fast non dominated sorting genetic algorithm (NSGA -Ⅱ), and the hydrogen storage optimal allocation model of PIES based on hydrogen production and storage of natural gas is proposed. Finally, taking a park in Xinjiang as an example, this paper analyzes the characteristics of power supply, electric load and heat load, operation economic benefits and the impact of natural gas price and carbon emission price on the configuration after hydrogen storage in the park, verifies the feasibility of improving the hydrogen production capacity and operation income of the PIES by configuring hydrogen storage for hydrogen production from natural gas, and points out the applicable scenarios.
