Flicker Reduction In Ac Network TRIZ Cases
- Reactive Power Control for Grid Flicker Prevention
Frequency-based lead and delay reactive power control suppresses 6-7 Hz grid voltage flicker from distributed power supplies while avoiding unstable gain settings.
- DFIG Rotor Control for Series-Compensated Wind Oscillation Damping
Selective filtering, PID feedback, and POD feedforward damping suppress sub-synchronous oscillations in series-compensated wind plants.
- Inverter-Based Resource Control for Drivetrain Oscillation Decoupling
Filtered voltage feedback and an energy buffer decouple drivetrain resonance oscillations from grid active power, improving stability.
- Island Microgrid VSG Impedance Control for Oscillation Suppression
D-axis current feedforward and voltage feedback reshape VSG impedance to suppress low-frequency VSG-LVSM oscillations in island microgrids.
