Avaliação do Potencial de Geração de Energia Solar e Eólica no Estado da Paraíba com o Uso de Base de Dados Interpolada

Abstract

The generation of electricity through renewable sources, such as solar and wind, is constantly growing due to the ecological and economic advantages associated with its use. Thus, the monitoring and analysis of climate variables such as wind speed and solar irradiation is of paramount importance to define the wind and solar generation potential of a region. In this context, the present study highlights the elaboration of a Paraíba State database (PB) making use of spatial data interpolation techniques to determine values where there are no measurements. Thus, from the official National Aeronautics and Space Administration (NASA) database, two interpolation procedures were evaluated. In sequence, the Kriging method for creating a base with exclusive resolution of 0.05◦was applied (latitude and longitude) in relation to the original base for analysis of the wind, solar and hybrid potential of the state. Finally, it was seen, based on the developed index, that the intermediate geographical region of Patos is favorable for solar power generation and the regions of Campina Grande and João Pessoa have a high wind potential, while some cities in the Campina Grande region had good rates for hybrid generation, i.e., wind and solar.
