Small-signal stability effects of turbine governors on power systems with high penetrations of integrated wind power

Abstract

This paper investigates the small-signal stability effects of coordinated turbine governors tuning on power systems with large-scale penetration of wind and in the presence of load disturbances. A case study is presented where the effects of the turbine governor are evaluated in the presence of a 20% increase in load active and reactive power for the IEEE 14-bus system. Results suggest that tuning the turbine governors in the presence of wind power generation may improve significantly the small-signal stability of an interconnected system.
