Abstract: The utilization of wind-solar coupled hydrogen production (WSC-HP) is regarded as a green hydrogen strategy. However, the volatility of wind-solar generation is the key challenge for stable hydrogen production and optimizing the cost-effectiveness. In this study, the circuit model of WSC-HP system with photovoltaic, wind, battery and electrolyser modules has been established using MATLAB/Simulink software. A comprehensive energy management strategy (CEMS) for WSC-HP system has been proposed aiming to ensure stable hydrogen production and improve energy utilization efficiency. Moreover, in order to evaluate the techno-economic of difference electrolyser for WSC-HP, alkaline electrolyser (AEC) and proton exchange membrane electrolyser (PEMEC) models were constructed and their polarization characterization were compared under different conditions. To achieve the lowest levelized cost of hydrogen (LCOH), genetic algorithm was utilized to optimize the capacity configuration across nine cities of China. The results show that CEMS can achieve stable hydrogen production output, with cell efficiency reaching 64.25 % in the AEC system. The range of LCOH for WSC-HP systems in nine regions varies from 3.78 $/kg (Chifeng) to 22.17 $/kg (Yichang), and the cost-effectiveness of AEC is superior to that of PEMEC. This study provides substantial guidance on stability modeling and regional economic technical analysis of WSC-HP system.
