Review on Backup Storage System in Wind Energy Conversion System

Abstract

This research work aims to minimize the power fluctuation in the power production of WECS using backup storage device during unexpected scenario. When the generating power is more than the grid capacity buck boost converter step down the power to grid capacity. Instead of wasting, the Excess amount of power will store in backup storage device with the help of controller. When the power generated is lower than the threshold value or Blade running in a slower speed to increase the power production by using backup power instead of draining the power from grid. This is used for ensuring the continuous power production with minimized power fluctuation. This process proceeds further by using DFIG with the combination of buck-boost converter and controller.
