Abstract
The Brazilian Power System is a hydrothermal system characterized by large
reservoirs arranged in complex cascades over several river basins. The Brazilian
Water Resource Policy determines that water resource management has to
provide multiple use of water. Thus, the System Operation Planning should
consider the use of part of the hydro plants reservoirs’ volumes as flood control
volumes for attenuation of possible floods, avoiding damage to downstream
areas. The use of reservoir volumes for electricity generation and flood control is
conflicting since the first use attempts to keep the reservoirs as full as possible
and the second one attempts to keep part of it empty at the same period. As a
result, some years, when the end of the rainy season inflows are low, the
reservoirs may not end the season completely filled. To address this problem,
this paper presents a methodology that changes the flood control volumes before
the end of the rainy season according to hydrological information. The
methodology proposed was tested in a Brazilian river basin to check its
applicability and effectiveness.
Keywords: flood control, reservoir’s operation, operation planning.
