Static analysis of voltage stability with DFIG
Science and Technology Development Journal, 2016 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.
