RESUMO

An application analysis of nonlinear programming is developed for hydropower systems optimization. The Paranapanema system is chosen like case study and treats aspects tied to hydrological series, that constitute the main input of optimization process. Different objective functions performance are analyzed for the hydropower optimization. It analyzes rules for emptying of hydropower reservoirs with configurations in parallel and in series. In this case a hypothetical system is used to allow larger system adaptation to the concepts that are tested. An application to the Paranapanema system is made, working with periods optimization of up to 20 years. New rules are defined based on the observation of the results of long period optimization. Also variation standards of power generation and reservoirs volumes are introduced. Comparisons with the observed operation are made. An application to real time operation is made, that defines operation policies for short term. This application has horizon of 12 months, departing of the current month and considering future scenarios based on climate prediction. The results show that is possible to have an optimization process understanding from the defined rules. The generation and volumes variation standards assist in the operation policies elaboration. Thus it has a general vision of hydropower system optimization, considering the results of optimization inside seasonal cycle jointly with the optimization long period implications.
