Dynamic characterization of wind farms and their impact in power systems oscillations

Abstract

This paper has two main objectives: to explain the dynamic characterization of wind farms as part of their integration in power systems using modal analysis and to present a qualitative development for understanding the main factors that impact on the damping of the oscillation modes by incorporating wind farms based on variable speed wind turbines. Moreover, such developments are validated by performing simulations on a 2017 peak scenario for the Uruguayan electrical system, showing a strong interaction between the hydroelectrics power plants located on the Río Negro and future wind farms Palmatir and Agua Leguas.
