Power System Stability Analysis in the Presence of Variable Speed Wind Generators

This paper aims to analyze Variable Speed Wind Turbine impact on transient behavior of a power system using time domain simulation. To this purpose, suitable mathematical models for Doubly Fed Induction Generators and Permanent Magnet Synchronous Generators with their control devices are considered. Simulations allow to assess the influence of VSWT on conventional synchronous generator dynamics after short-circuit fault occurrence.
