Resumo

This paper presents a case study related to the dynamic regularization of hydropower reservoirs. The main purpose is to anticipate the drawdown of a reservoir and obtain an empty space in the reservoir in order to allocate a high water volume. The software HydroExpert is used to perform all simulations required for the study. The problem is modeled according to the characteristics of a practical system and simulated for some operational conditions. The experiments on the study are assessed for two Iguaçu river basin hydropowers. The study results indicate the efficacy of the methodology to improve actions for critical hydrological periods which a feasible of occurring under operational conditions.
