Simulação de algoritmo de rastreamento de potência com uso do conversor buck

Abstract

Considering the increasing interest in the use of clean and sustainable energy, the aim of this undergraduate final paper is to study the photovoltaic solar system. The model suggested is based on studies that concern the photovoltaic energy system efficiency. The temperature, ambient condition, and irradiation that the system is submitted to directly affect the amount of power transferred from the photovoltaic solar module(s) to the battery bank or utility grid. Taking these characteristics into account, the Maximum Power Point Tracking (MPPT) is a way of optimizing the system by tracking the maximum current and voltage, and consequently the maximum power point (MPP), given certain irradiation. The studied algorithm is based on the Perturbation and Observation Method, which is going to be implemented on a system composed by a DC/DC converter and a PV cell array. This method is implemented accordingly to the solar panel characteristics ofthe current (I) and voltage(V) curve.
