Effects of Wind Generation Integration on Power System Transient Stability

Lackner, Christoph; Wilches-Bernal, Felipe; Chow, Joe H.

This paper analyzes the effects on transient stability of integrating a wind power plant (WPP) on a single machine infinite bus (SMIB) test system. Wind penetration in the system was increased and the impact of this integration on the critical clearing time (CCLT) of the system is studied. This study is performed separately for different WPP reactive power control schemes. Additionally, the paper determines the reduction in power output of the conventional generator necessary to keep a constant CCLT in the face of increases in wind penetration. The results show that this reduction is smaller than the wind power integrated, which is reflected in an increase in the total power transfered across the transmission line. Hence, the total power of the transfer path can be increased without transient stability concerns.
