Abstract
This paper analyzes the impact of using a series capacitor (SC) on voltage stability issues caused by the high penetration of wind energy in a transmission network. Voltage stability during normal operation, voltage sag characteristics, and low voltage ride through (LVRT) capability, harmonics and flickers produced by fixed-speed wind turbine (FSWT) and doubly-fed induction generator (DFIG) wind farms with series and shunt compensation are analyzed. The voltage source converter of a static synchronous compensator (STATCOM), the converter side of a DFIG and a load are considered as harmonics generating sources and are modeled according to IEC standard 61000. The induction machines of the wind farm are modeled with flicker coefficients as defined by IEC standard 61400 and voltage sag analysis is carried out using failure data. Nonlinear modeling and dynamic simulations are carried out in DlgSILENT PowerFactory environment. From the simulation results, it is found that using a SC with wind farm can enhance the system's stability and power quality.
