Compared to conventional synchronous generators, wind farms (WFs) have different impacts on power system small signal stability due to their physical and operational differences. In this paper, the small signal stability assessment of WF based on doubly fed induction generator (DFIG) is carried out. Control parameters are studied to investigate their impacts on the eigenvalues of a DFIG in a single machine infinite bus system. Besides, the effects of WF penetration on conventional power system-dominant modes are studied. It is shown that the DFIG-based WF would not considerably participate in electromechanical modes corresponding to the synchronous generators. It is concluded that the WF penetration into the power system has beneficial impacts on small signal stability.
