The static voltage stability analysis is carried out by V-Q sensitivity or Q-V modal analysis. These analyses are based on the Jacobian matrix of power flow calculation. This is regarded as load bus stability analysis. With DFIG of PQ mode, the wind generation bus is considered as the PQ bus. Due to the limits of converters, these PQ buses became very special and this influences on the voltage stability examining. This paper also examines the penetration level and the location of wind generation injection based on voltage stability. The reliability of the algorithm is illustrated in a study of 14 buses power network.
