Abstract: Rich wind power electrolysis of water to produce hydrogen, coupled with high-pollution steel smelting process, not only promotes the low-carbon transformation of the steel-making industry, but also effectively improves the wind power consumption capacity. In order to simulate the influence of green hydrogen steel smelting on wind power accommodation capacity, considering the reliability of steel smelting, the economy of hydrogen energy development and the environment of wind power generation, the internal interaction and feedback mechanism of green electricity-hydrogen energy-steel smelting coupling system are determined. Combined with the development trend of iron and steel industry and the potential of green hydrogen substitution, a dynamic model of green hydrogen iron and steel smelting system for improving wind power consumption is established. At the same time, considering the government support and the development of hydrogen production technology, a differentiated scenario is constructed to analyze the scale of hydrogen demand and the level of wind power consumption under different conditions. Based on the case of Xinjiang, it is shown that increasing the support of hydrogen metallurgy and improving the efficiency of hydrogen electrolysis can effectively improve the replacement rate of green hydrogen in the iron and steel industry and accelerate the reduction of green hydrogen cost, so as to realize the full consumption of wind power and effectively solve the problem of abandoned wind.
