| description | The modal analysis method is utilized to study the influence of doubly-fed induction generator (DFIG) on electromechanical oscillations. On this basis, the small signal stability region (SSSR) of power systems with DFIG in injection space is evaluated and the corresponding relationship between SSSR boundary and electromechanical oscillations is analyzed. The effects of the locations of DFIG on SSSR are considered. It is found that the boundary of SSSR consists of several smooth surfaces, which can be approximated with hyper-planes in engineering application. With the integration of DFIG, SSSR becomes smaller, thus indicating the deterioration of the small signal stability of the system. The 11-bus system with four generators is used to illustrate the proposed method. |
