Avaliação dos valores de tensão no PAC de uma rede de distribuição de energia elétrica com a variação da demanda dos consumidores após a inserção de geração distribuída fotovoltaica.

Abstract

In this undergraduate thesis are evaluated the voltage levels at the common coupling point of an electricity distribution network with variation in consumer demand after the insertion of photovoltaic distributed generation. The analysis is performed through a simulation of a model on an electricity distribution network model with the presence of photovoltaic distributed generation based on a real distribution network. The computer simulation program employed was OpenDSS. The simulations of the modeled distribution network were carried out with and without the photovoltaic distributed generation, in order to analyze its impact on the network. The results from the case study after the insertion of the photovoltaic distributed generation showed that there was a violation of the maximum voltage limit established by ANEEL. The overvoltage, which can damage electrical equipment, generate reverse power flow and impair power quality, occurred at times with high power injected into the network by the photovoltaic distributed generation in association with the low consumption of the loads.
