“…It also shows that local and plant level control of wind farm influence damping. Studies in [6], [7] using the IEEE 9 bus system and a 11 bus test system, respectively, show that the damping improved with increased wind penetration whereas [8], [9] show that damping is decreased with increased wind penetration. An Australian test system is used in [9].…”

The small signal stability of interconnected power systems is one of the important aspects that need to be investigated since the oscillations caused by this kind of instability have caused many incidents.With the increasing penetration of wind power in the power system, particularly doubly fed induction generator (DFIG), the impact on the power system small signal stability performance should be fully investigated. Because the DFIG wind turbine integration is through a fast action converter and associated control, it does not inherently participate in the electromechanical small signal oscillation. However, it influences the small signal stability by impacting active power flow paths in the network and replacing synchronous generators that have power system stabilizer (PSS).In this paper, the IEEE 39 bus test system has been used in the analysis. Furthermore, four study cases and several operation scenarios have been conducted and analysed. The selective eigenvalue Arnoldi/lanczos's method is used to obtain the system eigenvalue in the range of frequency from 0.2 Hz to 2 Hz which is related to electromechanical oscillations. Results show that the integration of DFIG wind turbines in a system during several study cases and operation scenarios give different influence on small signal stability performance.Index Terms-Arnoldi/Lanczos method, DFIG, DIgSILENT, eigenvalue analysis, power system operation, small signal stability, transient stability.

“…Another serious issue is the inter-area oscillation. Many studies have repeatedly shown that replacing conventional generation with doubly fed induction generator (DFIG)-based wind farms has a significant negative effect on the damping of inter-area modes [6][7][8][9]. Moreover, for the Eastern Interconnection (EI), the majority of existing and future wind generators are located in the northwestern part of the system, which is far from the load centers in the northeast.…”
