Research Objective
To model PEM electrolyzer operation as a controllable green-hydrogen load that supports frequency and voltage stability in a low-inertia renewable power system.
System Architecture
The PowerFactory model can include renewable generation, weak-grid bus, BESS or grid-support source, PEM electrolyzer load, transformer/interface branch, dynamic control model and RMS result variables for power, frequency and voltage.
Simulation Methodology
The study evaluates how electrolyzer active-power modulation, ramp constraints and operating limits contribute to grid support without violating hydrogen-production objectives.
Validation Scenarios
- Base load-flow with renewable and electrolyzer operating point
- Renewable power variation event
- Electrolyzer demand modulation for frequency support
- Low-inertia disturbance response
- Hydrogen load versus grid-stability trade-off comparison
Expected Graphs and Result Discussion
A complete result section should include the main waveforms, controller response, operating status and comparison tables needed for engineering thesis documentation. For this project, the important graph set includes:
- PEM electrolyzer active power
- Bus voltage and frequency
- Renewable power variation
- Grid-support controller output
- Hydrogen production operating window
Thesis and Research Extension Ideas
Add techno-economic hydrogen yield, electrolyzer efficiency, BESS coordination, MPC scheduling and low-inertia grid-code validation for journal-level studies.
