Power Quality Assessment of Wind Turbines by Matlab/Simulink

Wind turbines may cause significant impacts on the power quality of their connected grid. Voltage fluctuations produced by wind turbines are usually due to wind speed variations, power and voltage fluctuations. This paper presents simulations for numerical models of two wind turbine schemes, fixed and variable speed types, by using Matlab/Simulink, where simplified analytical model of wind turbines for voltage spectral analysis are illustrated for the power quality assessment.
