Application of FACTS controllers for wind power smoothening in grid-connected doubly-fed induction generator systems

摘要

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 increasing system reliability. This paper presents the impact of FACTS controllers on the long-term dynamic behaviour of power systems connected with wind farms based on doubly-fed induction generator systems. Wind speed variations over a period of 1200 s are monitored from the regional meteorological website, and the voltage oscillations/real power injections of the wind farm are observed with and without FACTS devices. EUROSTAG is used for carrying out time domain simulations.
