Energy Hierarchical Control Strategy of Photovoltaic Hydrogen Production Integrated System
摘要
To meet the future demand for large-scale application of hydrogen energy, an integrated technology of photovoltaic hydrogen production is proposed, and an energy hierarchical control strategy based on DC bus voltage control is combined with the characteristics of the electrolyzer. The system is divided into the system management layer and communication control layer, and the system is optimally controlled according to the higher-level scheduling to determine the corresponding working voltage threshold and operation status of each piece of equipment, to realize the system's stable operation and energy management. Based on the simulation of the MATLAB/Simulink software platform and 24 h operation under actual working conditions, the effectiveness of the energy hierarchy control strategy is verified, and the stability of the system in actual operation is ensured.
