This paper primarily focuses on Small Signal Stability Analysis of power system integrated with Wind Generation. Power System Stabilizer (PSS) is used with Wind Generation to investigate its effectiveness in damping out Local Area (Plant Mode) Oscillations. The effects are analyzed on 9-Bus Test System using established modeling and simulation techniques. Using SMIB based generator model, AVR lag and Oscillation Frequency are evaluated. Based on these calculations, Wind PSS is then modeled and introduced to provide the necessary damping thereby enhancing the system performance. The Local Area speed variations are used as the Reference Signal for Wind PSS to analyze its performance under Small Disturbances. Results validate the effectiveness of Wind PSS in damping the local area oscillations thereby enhancing small signal stability.
