Modeling of a maximum power point tracker for a stand-alone photovoltaic system using MATLAB/Simulink

摘要

Stand-alone photovoltaic (PV) systems are designed to operate independently from the electric utility grid, and are generally designed and sized to supply certain DC and/or AC electrical loads. Generally, components in the stand-alone system are in discrete form; therefore, the number of components, costs and power losses are higher. This article presents an approach to model and simulate 1.12 kW integrated maximum power point tracking charge controller and inverter. MATLAB/Simulink software is used in the implementation of system modeling and simulation in order to simulate and predict the behavior of the real stand-alone PV system.
