Abstract


Maximum power point tracking is considered to be an efficiency improving method applicable to the solar arrays. In this paper, Fuzzy-Big Bang-Big Crunch algorithm is applied in tracking of maximum power point. Simulation has been done in both MATLAB software where comparison made between Fuzzy-Big Bang and Fuzzy algorithm-alone. It has shown that in various temperatures and irradiations, optimized duty cycle achieved by proposed method is closer than fuzzy logic method to the values previously expressed in the referred source. Using those calculated values, the maximum error in Fuzzy-Big Bang method is only 0.0028 where fuzzy logic shows 0.0088. That is, the maximum error is reduced by 6.67% also efficiency of the system with Fuzzy-Big Bang algorithm is 5% improved in comparison with the Fuzzy method. The tracking system will quickly adapt itself even in rapidly environmental changes.
