Abstract

To reduce frequent start-stop cycles of electrolyzers caused by renewable energy volatility and enhance system hydrogen production efficiency, a three-stage optimal operation strategy for hydrogen production units is developed, along with an improved state-of-health （SOH）-based rotation control method. A bi-level optimization strategy for renewable energy-powered water electrolysis systems is proposed and validated using real-world data from the Jibei grid. The results demonstrate that hydrogen storage and chemical energy storage can collaboratively mitigate renewable energy power fluctuations. Compared to chain-based allocation and power equalization strategies, the proposed optimized operation strategy ensures stable hydrogen system performance under fluctuating power inputs while significantly improving hydrogen production efficiency.
