Operation control of wind solar hydrogen storage system The hydrogen production system based on wind and solar input has strong energy fluctuations. At the same time, the engineering safety requirement is to avoid frequent and rapid shutdown or startup of alkaline electrolyzers, so that the adjustment of hydrogen production speed has a large lag.
Energy storage is installed within the SRU solution, with a capacity of 259 kWh, ensuring that the system is able to harvest the maximum energy available from the wind and solar resources over each 24-hour cycle and can utilized when required.
The use of off-grid wind solar hydrogen production can effectively promote wind solar consumption and optimize energy structure, improve wind solar utilization efficiency, achieve on-site consumption of clean energy, and effectively explore the new direction of “green hydrogen” energy strategy. The output of renewable energy has great uncertainty.
System capacity configuration, as a key technology for off-grid wind solar hydrogen production system, has been studied by domestic and foreign scholars from multiple perspectives. Recent research on capacity configuration mostly focuses on optimization objectives, algorithms, and models .
The lithium batteries effectively mitigate power fluctuations, reduce the number of start-stop cycles of the electrolyzer, enhance its stability and lifespan, optimize hydrogen production efficiency, and reduce wind energy curtailment.
