Análise do impacto da geração distribuída nos níveis de tensão em redes de distribuição: estudo de caso na implementação de um transformador de distribuição com TAP variável em uma concessionária de energia

Abstract

The increasing incorporation of distributed generation, particularly photovoltaic, into the electrical distribution networks poses significant challenges in voltage regulation, essential for maintaining the stability and quality of the power supplied. This study focuses on the impact of distributed generation on voltage levels within a specific distribution network in Rio Grande do Norte, utilizing a distribution transformer with variable TAP as a technological solution. Through a quantitative approach, data collected from voltage variations in the network were analyzed, revealing the direct effects of implementing the variable TAP distribution transformer. The results indicate that this technology provides more effective voltage regulation, allowing fine adjustments that contribute to maintaining network stability despite load fluctuations caused by distributed generation. The research concludes that the implementation of transformers with variable TAP is a viable and effective strategy to mitigate voltage variation problems in networks with high penetration of distributed generation, recommending its broader adoption as part of an integrated solution for managing modern electrical networks.
