Estudo comparativo dos efeitos da integração de geração distribuída fotovoltaica no alimentador teste de 13 nós do IEEE

Abstract

Given the expansion of Distributed Photovoltaic Generation (DGPV) systems in distribution networks, driven mainly by incentive laws and price reductions for photovoltaic components, the following study was carried out with the aim of analyzing the effects associated with the implementation of these systems, focusing on voltage rise, reverse flow and technical losses. The study was carried out through simulations using the software OpenDSS, applying the IEEE node test feeder. The applied methodology proposed to investigate, through comparative analysis, the impacts mentioned in five different scenarios, where the base case consisted of the feeder without DGPV, the following three scenarios, connecting the DGPV in different nodes and the last one with the three DGPVs active simultaneously in the circuit. The results, discussed with the aid of graphs and tables, indicated the existence of reverse flow in all branches equipped with DGPV during the period of greatest solar irradiation (penetration). During this period, there was also an increase in voltage at the nodes analyzed and a reduction in losses in all cases with connection of the generating units, except for two times in scenario 5.
