Estudo comparativo de técnicas de rastreamento do ponto de máxima potência de um painel fotovoltaico.

Abstract

The generation of electrical energy from photovoltaic panels is configured as one of the best alternatives to reduce energy problems. However the conversion of this type of energy is relatively costly today. In order to minimize the output power cost, the maximum power point tracking (MPPT) of the PV output for all sunshine conditions is a key factor to maximize the power output of a PV system for assigned conditions of radiation and temperature. The essence of the RPMP is represented by the implemented algorithm devoted to find and maintain the operation near to the Maximum Power Point (MPP). This work presents a careful comparison among the most usual techniques, doing meaningful comparisons with respect to the amount of energy extracted, PV voltage ripple, dynamic response and use of sensors, considering that the models are implemented via MatLab/Simulink®.
