Abstract

This paper aims to evaluate the benefit of the combined operation of a hydro/solar system at USFB, specifically at the Três Marias Hydroelectric Plant (HPP), to raise the level of its reservoir. For this purpose, the hydrological/hydroelectric modeling of USFB and Três 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 Três 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 Três 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.

上圣弗朗西斯科盆地的水力/太阳能互补性：水资源管理的一种选择

本文旨在评估 USFB（特别是 Três Marias 水力发电厂 (HPP)）水电/太阳能系统联合运行对提高水库水位的益处。为此，在 RS MINERVE 水文/水电模拟平台上对 USFB 和 Três Marias 水电站进行了水文/水电建模。USFB 水文建模使用了三个水文均质区和水文概念模型 HBV。水电建模根据 Três Marias 水力发电厂的物理特性进行了调整。校准和验证过程使用了八个性能指标。所选方案分别评估了蒸散量增加 7%、降水量减少 10%和 20%的情况。Três Marias 水力发电厂的蓄水量和发电量是模拟过程的输出变量。根据模拟得出的结果，对预计的光伏电站（PVP）进行了尺寸计算。结果表明，在拟议的研究方案中，通过光伏电站的互补，可以增加水库的容积。因此，USFB 的水电/太阳能互补可以作为水资源管理的一个替代方案。
