Análise da estabilidade de tensão em um alimentador de distribuição real sob influência de geração distribuída.

Abstract

The quality of electricity provided by the electrical system to consumers depends on the smooth operation of the generation, transmission and distribution systems. Over the past few decades, especially after the oil crisis of the 1970s, demand for electricity has grown to a large extent. Distributed generation systems have emerged as a way of diversifying the energy matrix of countries, bringing generation to geographically points located closer to consumers. Although solar photovoltaic technology still has a small impact compared to other distributed generation sources, its increasing expansion is noticeable in the vicinity of distribution systems. The study was conducted to evaluate the influence caused by distributed generation when inserted into distribution systems by assessing the impact caused on a real distribution feeder. The simulations were performed using the Programa de Análise de Redes – ANAREDE software. The results showed an improvement in the voltage quality in the system buses near the distributed generation, by evaluating indicators such as the Voltage Stability Margin and the Voltage Collapse Point, showing that these systems contribute to the load relief and improvement of the voltage profile of distribution feeders.
