Análise de Dados na Flutuação Horária da Velocidade do Vento na Região Nordeste

Abstract

The increase in the world population has generated the need for greater energy supplies. However, its growth was not accompanied, in numbers, by the supply of energy. In this context, environmental factors also prove to be a reducing agent for energy security, since the occurrence of long periods of drought affect the production of electricity. In view of this fact, energy independence is sought through renewable sources, of which wind energy has been standing out in the sector. Thus, this article enables an analysis of the hourly fluctuation of wind speed in some cities in Brazil, focusing on the Northeast region with the purpose of determining a possible implementation of wind farms under the determination of the wind regime. As a result, the highest wind intensities occur in periods with low rainfall. Therefore, it proves the possibility of using wind resources as a source capable of reducing water energy dependence in months of drought. To produce the results, databases from the Instituto Nacional de Meteorologia were used, verifying hourly data from automatic stations over a period of ten years, between 2012 and 2022.
