Management of Low and High Frequency Components in Generation and Reduce Fluctuations Fed by DFIG Based WIND System with Battery and Fuel Cell

Abstract

The paper emphasizes on the application of hybrid energy storage systems to mitigate the effect of wind speed fluctuations, thereby ensuring smooth power output as well as improving the power quality at the PCC. To achieve this a control strategy is designed for managing the demand – generation fluctuations using a hybrid energy storage system in a wind dominated remote area power supply system consisting of a DFIG, fuel cell, a super capacitor, a dump load and main loads. Operation of fuel cell is coordinated with a super capacitor with a view to improving the performance of the fuel cell. In this model, the fuel cell storage system is connected to the load side of the RAPS system, whereas the super capacitor is connected to the dc bus of the back – to – back converter of the DFIG. The models are simulated in Matlab/Simulink environment.
