Comparative Study of Algorithms (MPPT) Applied to Photovoltaic Systems

Abstract

This work presents a theoretical study of maximum power point tracking (MPPT) for photovoltaic (PV) system. The study includes discussion of three MPPT algorithms (the Perturbation and Observation, Incremental Conductance and the Fractional open circuit voltage) and perform comparative tests between them using actual irradiance data. First the PV system with resistive load is discussed, the modelling and the simulation of the PV generator, the DC/DC converter and the three MPPT algorithms are carried out using MATLAB software.

Keywords
