Introduction

Frequency regulation

Keep it 50 Hz! Please!

How to make wind turbines “Grid Frequency friendly” ? Variable speed wind turbines

Inertial control Reverse control

Control system

Classical approach : using either PD controller or P controller with reset filter.

Simplified Model for DFIG and FPC wind turbine with supplementary control loops for fast primary response

Results + Future work

Propose a control approach replaces entirely the frequency regulation and the speed regulation loops in the classical approach.

Work on multi-area system and for turbulent wind speeds.

MPC controller

Δf

dΔf/dt

Results:

Simulation showing that the proposed scheme improves the frequency response after a sudden changes in load.
