Title A small - signal stability analysis of DFIG wind generation

This paper examines the small-signal stability impacts of high penetrations of doubly-fed induction generator (DFIG) wind turbines on power systems. It provides a basic overview of small-signal stability concepts and then examines the response of DFIG generation to two local contingency event. Using the New England 39 bus test system, this paper will demonstrate the stability implications of DFIG turbines utilizing terminal voltage control and fixed power factor control in response to reactive and active power loss events. By implementing terminal voltage control strategies in DFIG wind turbines, system stability is improved and allows for increased levels of wind penetration levels while maintaining a high level
