Modelling of Stand –Alone Wind Energy Conversion System using Fuzzy Logic Controller

Abstract: The concern for environment due to the ever increasing use of fossil fuels and rapid depletion of the conventional sources of energy has led to the development of alternative sources of energy. Wind energy, the kinetic energy associated with movement of large masses of air, is an inexhaustible source of energy which generates electricity without harming our environment. But it is unreliable energy source as wind conditions are uncertain and unpredictable. This paper focuses on developing a fuzzy logic controller based Stand-Alone Wind Energy Conversion System, where this controller manages power production and power storage according to wind conditions & load demand. This proposed system will help us to get a smooth AC output voltage to supply to fixed Load under any wind speed. The effectiveness of the proposed system for its application in autonomous wind energy system is verified with simulation results, which is carried out using MATLAB.
