Electricity is an essential element in the daily life of any society, and over time their consumption has increased considerably. In addition, the growing concern for the preservation of the environment has driven several research alternative energy sources in order to provide this growing energy demand, as well as reduce environmental impacts. Among the various alternative sources of currently available energy, photovoltaic solar energy has been considered an excellent choice because it is renewable, abundant and clean. In this context, the main objective of this work is to develop and implement computer modeling of a photovoltaic system, using Matlab-Simulink software, so that it is possible to analyze the impacts of the operation of these systems in the power quality in low voltage circuits. The model covers the solar panel, a DC-DC boost converter, the corresponding maximum power tracking control, the inverter voltage, phase locked loop and through of a coupling inductor, the connection of the entire system to low voltage power grid. The MPPT algorithm implemented in the system was Perturb & Observe (P&O), due to its good performance and low complexity. Finally, will also be presented the results of the simulation constituent parts of the PV array, as well as the results obtained in a case study considering a distribution system for low voltage.
