Análise dos impactos da geração eólica em sistemas de distribuição de energia elétrica em alta tensão.

Abstract

The work has as its theme the analysis of the impacts of wind power generation on high voltage distribution systems. The project was based on a case study for a high-voltage distribution system belonging to the power utility Energisa Paraíba. It was observed that, through computational simulations using the OpenDSS Electric Power Research Institute (EPRI) software, an unbalance in technical losses after the connection of two wind farms with a total installed capacity of 63 MW, result of poor power distribution due to intermittent generation. In Brazil, technical losses are regulated by the National Electric Energy Agency (ANEEL) through module 7 of the Procedures for Distribution of Electric Energy in the National Electric System (PRODIST), which specifies the acceptable levels for this type of loss, normally attributed to the operation of equipment such as transformers, voltage regulators, measuring instruments and conductive cables, that if not controlled, reduce efficiency and increase distribution costs. The study was based on the review of the main scientific articles related to the theme, motivated by the observation of the evolutionary process, more deeply on the renewable energy sources that contribute to the diversification and flexibilization of the Brazilian energy matrix.
