Modeling and simulation of a wind turbine system with ultracapacitors for short-term power smoothing

Abstract

This paper describes the modeling and simulation of a Permanent Magnet Synchronous Generator (PMSG) based Wind Energy Conversion System (WCES). The model includes all components from wind to the grid. This model is used to study various control algorithms as well as integration of ultracapacitor energy storage aimed at reduction of output power variations. Ultracapacitors are placed on the DC bus of the double conversion system to avoid extra power conversion stage.
