Integration of pitch regulated fixed speed wind turbine in a radial distribution system

This paper is concerned with developing model 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 terminal voltages for a specified wind speed. The proposed model has been used to investigate the impact of WTG integrating in power system by different number of WTG on terminal voltage variation. The application of the proposed model for the load flow analysis of radial systems having WTG has been described. The load flow method used in this paper is balance radial load flow based on forward-backward method. Simulation studies have been carried out on a 33 bus radial distribution system consisting WTG sources to illustrate the application of the proposed model developed by using MATLAB.
