Análise das implicações do uso da energia solar fotovoltaica na rede de distribuição

Abstract

ABSTRACT

Due to the increase in energy consumption, as well as the increase in tariffs charged by energy concessionaires, consumers have been looking for alternatives, such as photovoltaic solar energy, making them become prosumers, as they are producing part of the energy they consume. Although there are countless benefits of distributed generation, in the case of photovoltaic generation, there are some situations and factors that cause it to cause problems in the electricity distribution system, including overvoltage, when there is a large volume of installations in the same area. Given the above, the present work aimed to evaluate the impacts that the operation of photovoltaic energy generation systems can cause in the distribution networks, based on simulations in the 13-bus network of the Institute of Electrical and Electronic Engineers (IEEE), through the Open Distribution System Simulator (OpenDSS). Finally, comparing the values obtained with the energy quality parameters established by the National Electric Energy Agency (ANEEL). The results showed how the curve of each bus behaves in the proposed scenarios for the test system, how much the voltage has increased and, when comparing the tabled values in module 8 of PRODIST, the voltage has reached critical levels.
