Comparing the performances of MPPT techniques for DC-DC boost converter in a PV system

Abstract

The paper presents a comparison in terms of the performance of 3 maximum power point tracking methods used to achieve maximum output power from a photovoltaic system under varying irradiance. The maximum power point techniques considered in this study were Perturb and Observe, Incremental Conductance and Fuzzy logic. A literature review of related studies was conducted and a photovoltaic module modeling was presented. Moreover, a detailed theory of boost converter was also given. These 3 methods were discussed in detail and their flowcharts were presented. Simulation results from MATLAB/SIMULINK demonstrated a comparison between the 3 maximum power point tracking strategies. Results of current, voltage, and power from the photovoltaic module and the boost converter showed that the Fuzzy logic maximum power point tracking method had the best performance compared with other techniques.
