Impact of wind generation power electronic interface on power system inter-area oscillations

摘要

The dynamics governing power systems are being modified by the continued increase in the installation of wind turbine-generators (WTGs). This paper presents a small-signal analysis on the impact of the power electronic interface of large quantities of wind generation have on the inter-area oscillation of a two-area system. In particular the sensitivity of this inter-area mode with respect to: (i) increased wind penetration, (ii) loading conditions in the face of wind integration, and (iii) the active and reactive power control parameters of a WTG are presented in this paper. The results show that wind integration increases the damping of this oscillation for most of the cases except when implemented in the area that is importing power.
