OPTIMAL POWER MANAGEMENT IN STAND-ALONE WIND ENERGY SYSTEM USING FUZZY LOGIC

Abstract

In this paper, a wind energy conversion system using synchronous
generator and a battery to supply for a load is presented. The wind tuabin
power is often variable due to the variation of wind speed. In order to satisfy
the load demand, a fuzzy logic supervisor is used. This paper also presents a
maximum power point tracking (MPPT) method using fuzzy logic for stand-
alone variable speed wind tuabin system. The simulation results in
Matlab/Simulink software are presented to show the good performances of
the proposed controllers in stand alone wind energy systems.
