Abstract :
An improved control approach for DFIG (doubly-fed induction generator) is proposed, in order to enhance the damping of power systems integrated with wind farms through long distance. Firstly, the impact of wind power on the power system oscillations is investigated. Secondly, a supplementary damping control system (SDCS) is proposed and is added to the conventional DFIG control loop to improve the damping of inter-area modes. Finally, some simulations based on two areas and multiple areas power systems are carried out by DIgSILENT PowerFactory to verify the given method. Results reveal that the proposed control strategy can improve the power system damping.
