As a high-quality secondary energy carrier, hydrogen has application value in many aspects such as power generation, heat production, industry and transportation, especially in the field of difficult electrification and decarbonization, hydrogen becomes an inevitable choice of energy carrier in the future energy system and provides a good opportunity for the development of electric-hydrogen energy system. This paper explores the development of hydrogen energy and the demonstration application of electric-hydrogen coupling, and proposes three applicable scenarios for electric-hydrogen coupling application. Based on the concept of energy bus, the architecture of the coupling relationship between various devices in EH-IES is proposed and a mathematical model is established. The supply and demand balance of hydrogen load is realized by rationally arranging the output situation of each system, and then quantifying the characteristic indexes of grid operation, designing relevant objective functions and constraints, and solving the model using the improved scenario method. Analyzing the typical daily output of the system operation, the battery charging and the power input from the electrolyzer contribute 886.36kW and 1011.51kW respectively in the time period of 1:00-07:00.Comparing the operating costs of the three scenarios of the hydrogen refueling station, countryside, and industrial parks, in Scenario 2, the cost of the purchased power and the total revenue are 378,466 yuan respectively, 461654 yuan, the cost of purchased power increases dramatically, and the total benefit also decreases dramatically.
