Recently, the growing integration of wind energy into power networks has had a significant impact on power system stability. Amongst types of large capacity wind turbines (WTs), doubly-fed induction generator (DFIG) wind turbines represent an important percentage. This paper attemps to study the impact of DFIG wind turbines on the power system stability and dynamics by modeling all components of a case study system (CSS). Modal analysis is used for the study of the dynamic stability of the CSS. The system dynamics are studied by examining the eigenvalues of the matrix system of the case study and the impact of all parameters of the CSS are studied in normal, subsynchronous and super-synchronous modes. The results of the eigenvalue analysis are verified by using dynamic simulation software. The results show that each of the electrical and mechanical parameters of the CSS affect specific eigenvalues.

Keywords: wind turbine, doubly-fed induction generator (DFIG), dynamic modeling, eigenvalue analysis.
