Small signal stability enhancement of DFIG based wind power system using optimized controllers parameters
State space model of DFIG for small signal and transient stability is formulated. The controllers gains are optimized by PSO for dynamic performance improvement. Investigating the effect of optimized gains of controller on damping performance. The impact on the modes of oscillations with varying wind and strength of network. Enhancement in LVRT capability as per grid codes under fault and voltage sag.
