Estudo de conversores CC-CC utilizados em sistemas de painéis fotovoltaicos residenciais autônomos para aumento de eficiência energética

Abstract

This objective of this work is the study, design and simulation a DC-DC converter for autonomous residential solar photovoltaic system of low energy consumption, able to optimize energy production and compensate for the shadow effect. In order to do so, it is proposed the implementation of DC-DC converter of voltage lowering type, with the control is based on the technique of Maximum Power Point Tracker (MPPT), with the disturbance and observation algorithm. The proposed project was developed and simulated in the PSIM software, using tools that allow to simulate a photovoltaic panel with the characteristics and behaviors as real as possible. The simulations carried out during this work allowed us to prove that the technique used is able to provide the maximum power extracted from the solar panel to the batteries or loads. It is noteworthy that the obtained results show that the standard method has a good performance of the photovoltaic system, making it interesting for an application.
