GIS-AHP APPLICATION FOR IDENTIFICATION OF POTENTIAL AREAS FOR HYBRID PLANT INSTALLATION
The Brazilian Electricity Sector is a large hydro-thermo-wind generation system, whose share of renewable sources is significant, 84.8% of the electrical matrix was renewable in 2020. The increasing insertion of renewables contributes to the reduction of greenhouse gas emissions, but increases the complexity of system operation, as some sources are intermittent such as solar and wind or depend on environmental factors such as wind speed, the level of irradiation or the inflow of water. An alternative to the problem of the intermittence of these sources is the combination between them through the implementation of Hybrid Energy Systems. This system is characterized by the use of more than one primary source to generate electricity and, particularly, in the case of renewable energy, sources can be combined in such a way as to circumvent the problem of intermittency, contributing to the expansion of renewables in the electrical matrix. Although Hybrid Energy Systems have been discussed since the 1990s, it was only in recent years that this discussion has intensified with the publication of Technical Notes by EPE and the promotion of workshops on this topic. In this context, given Brazil's potential for the exploration of renewable energy sources, its extensive territorial area and the growing interest in hybrid energy systems, this work proposes a study to identify suitable areas for the construction of Hybrid Energy Systems. This study will take into account the main factors that, according to the literature, influence the choice of location for the installation of a power plant. The aim of this work is to identify locations with relevant characteristics for the implementation of a hybrid system through multicriteria analysis associated with the geoprocessing system.
