Selection of wind turbine for MPPT

Abstract

For proper utilization of wind energy it is necessary to drive the wind turbine at maximum power points at all wind speeds. Speed control of rotor is done within the operating range of wind turbines for maximum power point tracking(MPPT). Controllers are used depending upon the range within which the control of rotor angular velocity is required and this range varies for various turbines. Smaller range for rotor speed control supports the economy of controllers. So, for a particular wind energy location, selection of wind turbine should be done in such a manner that it requires minimum speed control to track maximum power during wind variations. In this paper an attempt has been made to analyze the performance of wind turbines for MPPT. Simulation results using MATLAB coding are found to be effective to propose few recommendations for the selection of wind turbines suitable for MPPT.
