Abstract :
This paper present a nonlinear controller for static VAR compensator (SVC) control system based on auto-disturbance-rejection control theory. This control theory is model free and with strong robustness. The work investigates the effect of this SVC on dynamic voltage stability of wind farm composed of fixed-speed induction generator (FSIG). The SVC with ADRC provides an optimal signal in order to avoid the low voltage and voltage fluctuation problem which come from wind farm integration. Simulation results show that ADRC is an effective solution to overcome anticipative problem.
