Due to the intermittent, fluctuating and counter-peak characteristics of wind power generation, the access to a high proportion of wind power has an impact on the stability of the power system operation, and also leads to problems such as poor power quality and serious wind abandonment. This paper aims to maximize the comprehensive benefits of the whole life cycle of the wind-hydrogen system taking into account the emission reduction benefits, constructs an optimization model of the hydrogen storage capacity allocation of the wind-hydrogen system, and discusses the optimal capacity of the hydrogen storage allocation under different application scenarios, and analyzes and compares the operation of the wind-hydrogen system under two scenarios on typical days of the seasons as well as the corresponding economic and emission reduction benefits, which verifies the economic and environmental feasibility of the wind-hydrogen system. The economic and environmental feasibility of the wind-hydrogen system is verified. The results show that the consideration of demand response can increase the wind power supply while reducing the energy storage configuration, reduce the optimal configuration capacity of the hydrogen storage system, and the optimal hydrogen storage configuration capacity of scenario 1 is 4400kW, and the optimal hydrogen storage capacity of scenario 2 is reduced to 4200kW, and the overall economy of the wind-hydrogen system can be improved, and the NPV of the whole-life cycle economic benefit is increased to 32.588 million yuan, and the IRR is increased to 20.44%. 20.44%, and various types of pollutant emissions are reduced. The wind-hydrogen system can not only significantly reduce carbon dioxide and other pollutants, with significant emission reduction benefits, but also significantly improve the economic benefits, and at the same time, considering the participation of adjustable loads in demand response can further improve the economic and comprehensive benefits of the wind-hydrogen system, and improve the level of wind power consumption.
