A Novel Approach of Wind MPPT Using Fuzzy Logic

Abstract

The key motive of this article is to carry out the optimum power as well as supreme power from wind turbine using fuzzy control technique. The wind power system largely relies on wind velocity and pitch angle, so Fuzzy control technique is used to extract supreme power in an efficient method which minimizes the dislocation in the system reaction. For developing the fuzzy-based wind MPPT system, a DC/DC step-up power converter is constituted to trigger the gate of its MOS-FET switch by applying Fuzzy rules for regulating rotor acceleration of wind generator. The fuzzy controller provides a signal as well as duty cycle as output through pulse width modulation (PWM) that switches the gate of DC/DC converter. Simulation results show that the developed fuzzy-based wind MPPT structure can perform nonlinear functions of random difficulty and cover an extensive range of working conditions.
