Abstract

To address the issues of improving electricity utilization and hydrogen production stability in photovoltaic hydrogen production systems

a dynamic coordination control strategy based on maximum efficiency point tracking is proposed

considering both the advantages of direct coupling for high electricity utilization and indirect coupling for flexibility and control. First

photovoltaic power generation models

electrolysis hydrogen production efficiency models

and battery voltage regulation models are established. In off-grid mode

the particle swarm optimization algorithm and sliding mode control are used to achieve maximum efficiency point tracking for the electrolyzer. Then

based on the maximum output power of the photovoltaic system and the battery's state of charge

dynamic coordination control optimization of the photovoltaic hydrogen production system is performed. Finally

the algorithm is validated through simulations. The results show that the proposed method can flexibly switch between five different operating conditions by evaluating the maximum output power of the photovoltaic system and the battery's state of charge. It can also track the maximum efficiency point in real-time when the operating temperature changes

thus improving the system's energy conversion efficiency and reducing current ripple.
