Estudo dos impactos da geração alternativa residencial de energia elétrica na rede de distribuição

Abstract

This work is dedicated to the study of the impacts of electricity generation arising from alternative sources in the distribution network, based on the knowledge acquired in the voltage stability and network analysis in the time domain disciplines. Through an analysis about the energy quality inherent in wind generation systems, a qualification of the impacts of this type of generation in the electrical distribution network is done. This work includes in its theoretical topics related to power quality, wind and solar generation, among others. As a case study, a specific situation involving wind turbines, where the problems of variation in wind speed and resulting non-uniform power generation is studied in order to get solutions to mitigate these effects, concentrated in the power conversion system. The objective of this work is to define acceptable standards of quality power to facilitate the equipment specification and propose practical solutions for both existing installations and future alternative energy sources-based installations.
