Wind Energy Conversions Systems (WECS) has gained importance in the recent years as a prime source of distributed generation, in which variable speed wind turbine with direct driven PMSG and power electronic interface is the most commonly used system exhibiting variability in the output power as a result of change in the prime mover (wind speed). When such a configuration is interconnected to the grid it introduces various challenges to the network in terms of power quality issues, stability

These devices are operated either by supplying or absorbing active and reactive power or by altering the grid parameters by controlling either line reactance or voltage control. FACTS controllers have been mainly used for solving various power system steady state control problems. This paper proposes stability enhancement of WECS using a FACTS device called Static Synchronous Series Compensator (SSSC) when incorporated with a Frequency Oscillation Controller.
