Research Objective
To tune fast active-power support from HVDC links and PEM electrolyzer load flexibility for improving inter-area frequency response, damping and power-balance recovery in hybrid AC/DC networks.
System Architecture
The network combines multiple HVAC areas, HVDC interconnection, converter stations, renewable buses, PEM electrolyzer load blocks, generator/load events and controller channels for active-power modulation and frequency support.
Simulation Methodology
The study performs load-flow initialization, RMS disturbance simulation and tuning of active-power support gain, ramp limits, delay, deadband and electrolyzer demand response. Performance is compared using nadir, settling time and tie-line power deviation.
Validation Scenarios
- Multi-area HVAC base case and HVDC operating point
- Generator outage or load disturbance event
- PEM electrolyzer demand response activation
- HVDC fast active-power modulation test
- Sensitivity study of controller gain, deadband and response delay
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:
- Area frequency deviation
- HVDC active-power exchange
- PEM electrolyzer power modulation
- Tie-line active-power oscillation
- Optimization fitness or tuning comparison
Thesis and Research Extension Ideas
PSO, GWO, reinforcement learning, MPC coordination and hydrogen-production economics can be linked with PowerFactory RMS results for a strong thesis contribution.
