Studying of the energy quality of a distribution network of Marechal Deodoro-AL with the integration of solar photovoltaic generation

The present work proposes to evaluate the contribution of the insertion of photovoltaic solar generation in the power quality in a distribution network in Marechal Deodoro-AL. The simulations were performed through the ATPDraw (Alternative Transient Program) software. These simulations were in situations of overload, considering the system in maximum imbalance allowed by PRODIST (Distribution Procedures) and in permanent regime. The currents of the photovoltaic solar generators have a unit power factor, and they even inject about 320 A in one of the buses of the feeder segment. The results obtained through graphs show that with the insertion of photovoltaic systems in the network there is a contribution of up to 2% in the voltage level, in case of overload, contributing in the quality of energy to the consumer.
