Análise do impacto da instalação de reguladores de tensão na qualidade da energia elétrica frente às consequências de uma densa concentração de geração distribuída: estudo de caso

Abstract

Photovoltaic solar energy has been rapidly expanding in Brazil in recent years. The growth in solar panel installations, both in residential and commercial settings, reflects the pursuit of cleaner and more economically viable energy alternatives, solidifying solar energy as one of the main renewable sources in the Brazilian energy landscape. However, this context has brought significant changes to the planning and operation of electricity distribution systems. The networks, initially designed for unidirectional power flow, are now facing challenges such as overvoltage, power factor variations, and increased technical losses. These challenges make it essential to develop new alternatives to mitigate the effects, reconsidering the maintenance, operation, expansion, and technical/economic planning activities of energy service providers. In this study, which aims to contribute to the technical debate on the subject, the Voltage Regulation Controlled by Power (VRCP) methodology, implemented by the energy distributor of Rio Grande do Norte, is presented. This methodology aims to improve the quality of electricity delivered to consumers in an area with a high concentration of clients using photovoltaic generators
