The impact of wind farms with doubly fed induction generators on power system electromechanical oscillations

Jafarian, M.; Ranjbar, A.M. - In: Renewable Energy 50 (2013) C, pp. 780-785

Introduction of large amounts of new wind generation can affect the small signal stability of power systems with three mechanisms: displacing synchronous generators (SGs); reducing SGs power generation; and the dynamics of wind farms (WFs) interacting with the electromechanical mode of SGs. In...

A new control strategy for small wind farm with capabilities of supplying required reactive power and transient stability improvement

Samiei Sarkhanloo, Mehdi; Sadeghi Yazdankhah, Ahmad; … - In: Renewable Energy 44 (2012) C, pp. 32-39

This paper presents a new control strategy for a small scale wind farm which is composed of both fixed and variable speed wind turbine generator systems. Fixed speed wind generators (FSWGs) are largely dependent on reactive power, so they require large reactive power when a short circuit fault...
