Enhancement of Power Quality on Wind Generation Systems by Superconducting Magnetic Energy Storage System

Abstract

The power quality (PQ) requirement is one of the most significant concerns for power companies and their customers. In this paper, Superconducting Magnetic Energy Storage (SMES) is applied on wind energy conversion systems that are equipped with Doubly Fed Induction Generators (DFIGs) during the presence of voltage sags and swells in the grid side. Without SMES, certain levels of voltage sags and swells in the grid side may cause a critical operating condition that may require disconnection of WECS to the grid. Voltage sags are the one of important power quality problem. The selection of a SMES unit in this project is based on its advantages over other energy storage technologies. Using the Hysteresis current control approach in conjunction with a Neural network controller, the SMES unit fruitfully and effectively enhances the performance of the DFIG during voltage sag and swell events in the grid side. The modeling of the wind energy conversion systems (WECSs) that are equipped with doubly fed induction generators (DFIGs) with SMES is build using MATLAB/Simulink.
