Simulated Wind Power Profiles for Megawatt-Scale Hydrogen Electrolysis

Comprising simulated wind energy profiles for coupling with a 1.25-MW proton exchange membrane electrolyzer. The data, generated using OpenFAST for a 3.4-MW IEA reference wind turbine, includes hour-long experiments varying wind speed (5, 7, or 9 m/s) and turbulence intensity (Class An or C). It is intended for planning and validating models of megawatt-scale hydrogen technologies.

Use Cases

• Train an LSTM model on 1-Hz power-to-current data to forecast hydrogen mass production from simulated wind profiles.
• Validate electrolyzer performance models using data on electrolyzer ramp rates (200 or 400 amperes per second) under different wind turbulence classes.
• Analyze the efficiency of hydrogen production when scaling the system to represent two 1.25-MW electrolyzers (2.5 MW total) versus a single unit.
• Perform uncertainty quantification on hydrogen output using the varied experimental parameters of average wind speed and turbulence intensity.

Strengths

• Data is captured at a high 1-Hz frequency, enabling detailed temporal analysis of system dynamics.
• Experiments are systematically varied across key parameters: three average wind speeds (5, 7, 9 m/s) and two wind turbulence classes (A, C).
• Based on a specific, well-defined 3.4-MW International Energy Agency (IEA) reference wind turbine model.
• Explicitly documents the use of two distinct electrolyzer power supply ramp rates (200 and 400 amperes per second).

Limitations

• The dataset is based on simulations (OpenFAST) and scaled profiles, not direct measurements from physical wind turbine coupling.
• The temporal coverage is limited to hour-long experiment profiles, which may not capture longer-term operational cycles or seasonal variations.
• Geographic scope and real-world site conditions are not specified, as the wind profiles are simulated.
