摘要： The Distributed Generation (DG) is characterized by the production of electricity connected to the distribution network or to the local network consumers, using renewable or non-renewable resources, technology. Excessive use of DG systems connected to the distribution network may regulation, compromising the system control and protection devices and the reliability, due to the voltage increase in the DG connection point. In this context, this work presents an analysis of frequency that performs a photovoltaic data transmission interface with an electric grid, as a new possibility of voltage control and reactive power (volt/VAr) in sets with the usual instruments of control used in electricity distribution networks. The analysis consists of performing the volt/VAr control from the frequency inverters in low or medium voltage networks, where the inverter assists in voltage regulation through the insertion and/or absorption of reactive power in the distribution system. In order to demonstrate the proposed methodology application, tests were performed on a standard IEEE 13 node in the OpenDSS? software, comparing the voltage profiles and position adjustment of voltage control for a given DG penetration index and different inverter operating conditions.
