Description
Summary:This paper aims to evaluate the benefit of the combined operation of a hydro/solar system at USFB, specifically at the Tres Marias Hydroelectric Plant (HPP), to raise the level of its reservoir. For this purpose, the hydrological/hydroelectric modeling of USFB and Tres Marias HPP is carried out on the RS MINERVE hydrological/hydroelectric simulation platform. USFB hydrological modeling is done using three hydrologically homogeneous regions and the hydrological conceptual model HBV. The hydroelectric modeling was adjusted to the physical characteristics of the Tres Marias HPP. The calibration and validation process uses eight performance indicators. The chosen scenarios evaluate an increase of 7% in evapotranspiration and a decrease of 10% and 20% in precipitation, respectively. Water storage and energy generated at the Tres Marias HPP are the output variables of the simulation process. From the results obtained in the simulation, the projected Photovoltaic Plant (PVP) is dimensioned. The results show that with the complementarity of the projected PVP it is possible to increase the volume of the reservoir for the proposed study scenarios. Therefore, hydro/solar complementarity at USFB can be an alternative for the management of water resources.

Este trabalho avalia o beneficio da operacao combinada de um sistema hidro/solar na BASF, especificamente na Usina Hidreletrica (UHE) Tres Marias, a fim de elevar o nivel do seu reservatorio. Com este proposito, realiza-se a modelagem hidrologica/hidreletrica na plataforma de simulacao RS MINERVE. A modelagem hidrologica e feita utilizando tres regioes hidrologicamente homogeneas e o modelo conceituai HBV. A modelagem hidreletrica foi ajustada as caracteristicas fisicas da UHE Tres Marias. Os cenarios escolhidos avaliam um aumento de 7% na evapotranspiracao e uma diminuicao de 10% e 20% na precipitacao, respectivamente. O armazenamento de agua e a energia gerada na UHE Tres Marias sao as variaveis de saida do processo de simulacao. A partir dos resultados da simulacao, a Usina Fotovoltaica (UFV) projetada e dimensionada. Os resultados mostram que com a complementariedade da UFV projetada e possivel aumentar o volume do reservatorio para os cenarios de estudo propostos. Portanto, a complementaridade hidro/solar na BASF pode ser uma alternativa para a gerenciamento dos recursos hidricos. PALAVRAS-CHAVE: modelagem de bacia hidr
