Study of Power Quality Issues in Wind Distributed Generation System

This paper presents impact of power quality in the presence of grid disturbances and wind system penetration using Distribution Static Compensator (DSTATCOM) and Dynamic Voltage Restorer (DVR). An IEEE 13 bus distribution test feeder with DSTATCOM, DVR and doubly fed wind generator (DFIG) is used for the study. Power quality events during grid disturbances such as voltage sag/ swell and harmonics have been studied in association with DSTATCOM and DVR. The power quality disturbances due to wind generator outage have been investigated. The study has been carried out using MATLAB/SIMULINK 2014a environment.The proposed method has been proved to be effective in improvement of power quality with Wind penetration to the system.
