| description | Modeling of the hydrogen production systerm is of great significance to energy consumption reduction and the study of the interaction characteristics of different flows in integrated energy systems. The working principle and physical characteristics of the alkaline electrolytic water hydrogen production system are analyzed. A static model of the alkaline electrolyzer for hydrogen production is established through electrochemical equations and parameter fitting. Based on the model， a dynamic model of the equivalent circuit of the electrolyzer load is analyzed. The broadband impedance spectrum （BIS） of the electrolyzer is obtained by using DC plus small disturbance voltage. The values of impedance parameters in the model are calculated by Fourier analysis. Finally， the values are simulated by a model established in MATLAB environment. The accuracy of the dynamic model is verified by in comparison to the measured data. |
