Abstract

The interest in research structures that allow the integration of alternative energy sources as a way to minimize the effects of energy crisis has been encouraged by regulatory agencies and by the Ministry of Mines and Energy. As a result, this research project is looking for ways to produce electricity through distributed generators with high quality conected to the grid that uses as a primary source an alternative source energy.For the effective operation of distributed generators, the use of photovoltaic panels and accumulators of energy such as batteries and ultra-capacitors represent an efficient solution and low environmental impact. Due to the characteristic of such sources, it is necessary to use three inverters, a step-up DC-DC used to interface the photovoltaic panel, another DC-DC bidirectional used for charge and discharge of batteries, a bidirectional to maintain power storage in the ultra-capacitor and a voltage source inverter DC-AC (VSI) that will act as an interface between the grid and distributed generation. The latter should control the flow of energy between the grid and distributed generation by imposing current (tethered operation) or imposing of voltage (islanding mode).Furthermore, the connection of distributed generation systems (DG) in distribution networks can cause effects more harmful than beneficial if previous studies about the installation location of GD are not made. Thus, knowledge of the behavior of GD will grant more information to the electric utilities and producers of energy from their behavior when these systems are connected to grid.
