Abstract
The increasing power demand has led to the growth of new technologies that play an integral role in shaping the future energy market. Keeping in view of the environmental constraints, grid connected wind turbines are promising in increasing system reliability. This paper presents the impact of Flexible A.C. Transmission System (FACTS) controllers on the dynamic stability of power systems connected with wind energy conversion systems. The wind generator model considered is a variable speed doubly - fed induction generator model. The stability assessment is made first for a three phase short circuit without the FACTS controllers in the power network and then with the FACTS controllers. The dynamic simulation results yield information on (i) The impact of faults on the performance of induction generators/wind turbines. (ii) The change in controllable parameters of the FACTS controllers following the disturbance. (iii) Transient rating of the FACTS controllers for enhancement of rotor speed stability of induction generators and angle stability of synchronous generators.
