Modelagem matemática do deplecionamento/replecionamento de recursos hídricos e geração de energia em usinas hidrelétricas

Abstract

The production of electricity in hydropower plants is influenced by the reservoir level, which can vary due to natural and human factors. The water shortage caused by the deregularization of rainy periods are shocking factors for reduction of hydraulic potential. However, the exploitation of water resources when considering cascading hydroelectric power plants maximizes electricity generation. Although this is a viable alternative, there is a need to improve the management of reservoir levels by observing depletion/repletion, and considering the generation of energy from each hydropower plant present in the same hydrographic basin. In this context, this study aims to evaluate energy production in hydropower plants through the analysis of reservoir level data and energy generated daily. For this, a mathematical model was developed that seeks to establish the relationship between the reservoir level and energy generation. The implementation of this model helps in making strategic decisions, minimizing waste and ensuring a continuous and reliable supply of electricity. The results of this study also contribute to improving the management and operation of unit and cascade hydropower plants, providing a more sustainable and efficient energy matrix.
