GIS-AHP APPLICATION FOR IDENTIFICATION OF POTENTIAL AREAS FOR HYBRID PLANT INSTALLATION
The Brazilian electricity matrix is a predominantly large-scale hydro-thermal-wind generation system, in which renewable sources play a significant role, representing 78.1% of the domestic electricity supply in 2021. The increasing integration of renewables into the electrical system poses challenges, mainly due to the intermittent nature of some sources, such as solar and wind. One alternative is the combination of complementary sources through hybrid electrical energy systems. The regulation of such systems is recent, and there are not many studies exploring this subject. In this context, this study aimed to identify municipalities in the State of São Paulo with the potential for the implementation of hybrid power plants, considering solar, wind, and biomass sources, as well as the proximity to hydroelectric plants, taking into account technical, economic, social, and environmental criteria. For this purpose, the QGIS geoprocessing system and the Analytic Hierarchy Process (AHP) and Weighted Linear Combination (WLC) multicriteria analysis methods were used. The methodology yielded satisfactory results, indicating municipalities that already have installed power plants, confirming their potential. Thus, this methodology can assist in the pre-selection of potential locations for the development of hybrid power plants, contributing to the planning and efficient use of the country's energy resources.
