Metodologia para Linearização do Painel Fotovoltaico através do método de Thévenin e Aplicação de Álgebra Linear

Abstract

In photovoltaic energy systems, both photovoltaic panels and switching converters have non- linear and time-variant characteristics, which results in a complex control, resulting in a more accessible methodology for performing the calculation. This paper aims to contribute with a methodology for obtaining the linearization of photovoltaic panels in series and parallel, presenting new linearization models for more than one photovoltaic panel and opening a discussion on current proposed models. The main objective is to present the modeling of the photovoltaic panel and the linearizations referring to the set of proposed panels. The validation of these models will be carried out through graphical analysis performed by the Matlab/SIMULINK software, considering the linearization of the series, parallel and mixed circuit.
