Contribution of Doubly Fed Wind Generators to Oscillation Damping
TL;DR: In this paper, the effects of increased wind power penetration by doubly fed asynchronous generators (DFAGs) on oscillation damping are investigated, and it is shown that the general trend for DFAGs is to increase interarea oscillations, however, there are exceptions for certain penetration levels (not necessarily large), for which the voltage control (VC) option of DFAG can reduce damping.
