For the last few decades, there has been rising concern across the globe about depletion of conventional energy sources and the consequent energy crisis. Simultaneously, search for other energy sources, such as wind energy and solar energy, has been gaining momentum as well. Particularly, wind energy has become a viable alternative source of energy. As the wind power penetration continually increases, stability of the grid-connected doubly fed induction generator (DFIG)-based wind turbine system has become essential for wind power generation. This study presents the influence of a grid-side converter current dynamics on the small-signal stability by using the eigenvalue and participation factor technique which provides five distinct system modes, namely mechanical (M), stator electrical, converter electrical, electro-mechanical and non-oscillatory mode. In addition, flexible alternating current transmission system device has been incorporated to examine its effect on the system stability at different compensation levels. Furthermore, the sensitivity of a grid-connected DFIG system concerning system parameter variations and its impact on stability of the system modes has been investigated. Simulations have been carried out in the MATLAB/Simulink environment.
