Comparative analysis of the perturb-and-observe and incremental conductance MPPT methods

Abstract

This paper presents a comparative study between two maximum power point tracking (MPPT) methods in Matlab/Simulink program that are perturb-and-observe method and incremental conductance method. Starting from the implemented model of the photovoltaic (PV) array together with the buck converter and its MPPT control have been simulated the PV systems with both MPPT algorithms at different solar radiation and temperature, and finally are presented the simulations result depending on irradiance and temperature.
