Comparative stability analysis of DFIG-based wind farms and conventional synchronous generators

Abstract:

This paper presents a comparative stability analysis of conventional synchronous generators and wind farms based on double feed induction generators (DFIG). Based on an appropriate DFIG wind generator model, PV curves, modal analysis and time domain simulations are used to study the effect on system stability of replacing conventional generation by DFIG-based wind generation on the IEEE 14-bus benchmark system, for both fixed power factor and voltage control operation. The results show that the oscillatory behavior associated with the dominant mode of the synchronous generator is improved when the DFIG-based wind turbine is connected to the system; this improvement in the damping ratios is more evident when the wind turbines are operated with terminal voltage control. © 2011 IEEE.
