Análise do impacto na qualidade de energia causado pela conexão de geração distribuída fotovoltaica de até 50kW

Abstract

The present work aims to provide information on the current state of distributed generation in Brazil, both in terms of standardization and number of connections, as well as presenting to the energy distributor the results of measurements performed through an energy quality analyzer in a commercial facility which has a photovoltaic system connected to the grid, focusing on the energy quality parameters defined in standards, in order to identify whether the parameters are in connection point. A bibliographical research was carried out on the possible impacts that DG can have on a radial distribution system that is the most common in Brazil today. It was verified through the results and graphs compiled that at the point of connection there was a small increase in voltage profile and not many changes in voltage harmonic distortion.
