Voltage fluctuation of powersystem consisting wind farm

Abstract

This study is concerned with developing models of pitch regulated fixed speed (PRFS) type of wind turbine generators (WTG) used as distributed generation (DG) sources and demonstrating its application for steady state analysis. The model for this class of WTG developed here facilitates the computation of point of common coupling (PCC) voltages for a specified wind speed. The proposed model has been used to study the impact of WTG integrating in power system by different number of WTG on terminal voltage variation. In addition, the fluctuation of voltage has been investigated in different bus bars of power network by increasing the number of WT according to different wind speed samples. The application of the proposed models for the load flow analysis of radial systems having WTG has been demonstrated. The load flow method that has been used in this paper is balance radial load flow based on forward-backward method. Simulation studies have been carried out on a 33 bus IEEE radial distribution system having WTG sources to illustrate the application of the proposed models which is developed by using Matlab.
