With the growing interest of consumers of electric energy for the benefits brought by the Distributed Generation (DG), there is a concern about the impact that such insertion will bring to the distribution networks. After the changes brought to the sector by the Normative Resolution (REN) 687/15 of the National Electric Energy Agency (ANEEL), which led to the rapid growth of the sector in the country, there was a need for studies to mitigate the technical and commercial impacts that this type of generation brings to the electricity sector. One of the impacts brought by the insertion of DG in the distribution networks is the reduction of its Power Factor (PF), due to the characteristic of distributed generators of only injecting active energy, remaining with the consumption of reactive power. There is, however, another point brought by GD that also negatively impacts the PF of the network, which is the insertion of harmonic distortions by photovoltaic inverters. In this work, a study and simulations of the impact of the insertion of harmonic distortions caused by photovoltaic systems on the power factor of the distribution grid will be presented.
