Impacts of Photovoltaic Systems on a Brazilian Distribution Feeder using OpenDSS

Abstract

The growing demand for electricity, environmental concerns renewable energy sources and improved electricity supply has created a new scenario in the global electricity sector. So, it has been necessary adjustments and reanalysis of the electrical networks.which for the most part were not built to be active networks, with distributed generation of energy. Thus, the present work proposes to analyse the behavior of the indices of losses and voltage levels of areal Brazilian feeder, which does not have details of the actual load profiles of the consumers. In this approach, different load profiles and the impacts caused by different penetration levels of distributed generators in the network will be considered. For these analysis will be used OpenDSS that has been used by companies and researchers around the world. The analysed feeder is very extensive and is located in a electric utility in the interior of Brazil and the generation assumed is the photovoltaic that has grown substantially in the country. In the results will be noted those impacts can be positives and negatives to the system.
