| description | Energy storage is one of the important methods for mitigating the fluctuation of renewable energy. A refined simulation model is presented that can describe the material transport and energy conversion in a proton exchange membrane electrolyser (PEM). The model is constructed based on the component structure of the PEM, as well as the principles of electrochemistry and thermal equilibrium, taking into account the phenomenon of internal gas transport across the membrane. Based on this model, an electricity-hydrogen coupling system including electrochemical energy storage and hydrogen energy storage is established. A two-layer coordinated control strategy considering the charge state of electrochemical energy storage and the hydrogen state of hydrogen energy storage is proposed. The upper-layer power allocation considers the changes in electric and hydrogen load demands in the system, and uses the battery state of charge and hydrogen storage tank state of hydrogen as important constraints to determine the operating modes for each device in the system. The bottom layer control achieves power tracking adjustment by utilizing PQ control, VQ control, and other methods according to equipment operating characteristics. The effectiveness of this proposed model and control method is verified through simulations under several different operation scenarios. The research results can provide support for the optimization of control strategies for wind-photovoltaic-hydrogen storage systems. |
