Comparative Study Of Maximum Power Point Tracking Techniques For Photovoltaic Systems

Abstract

This paper presents a comparative study among maximum power point tracking methods for photovoltaic systems. The comparison takes into account steady state error, dynamic response and efficiency in a large power range. In special, an extensive bibliography and a classification of many maximum power point tracking methods is presented. Computational simulations with fast changes in the solar irradiance have been done and the best maximum power point tracking technique is chosen. Experimental results corresponding to the operation of a photovoltaic converter controlled by a digital signal processor are also presented.
