Fuzzy logic based maximum power point tracking technique for a stand-alone wind energy system

Abstract

This paper describes the use of fuzzy logic to develop a simple and reliable maximum power point tracking (MPPT) technique for a stand-alone wind energy system. The system includes a wind turbine without the use of a gearbox, a permanent magnet synchronous generator (PMSG), a three-phase bridge rectifier and a DC-DC boost converter. The simulation results obtained by using MATLAB/Simulink show that the proposed MPPT method always results in the maximum output power corresponding to the current wind speed.
