The hydrological regime of a river is driving force its ecosystem. operation dams and locks has significant impacts on the situation rivers. objective this study was to change variability precipitation data in Senegal River basin assess discharge caused by Manantali hydroelectric dam. Based IHA (Indicators Hydrologic Alteration), range thirty-three parameters calculated alteration associated wi...

The starting point of this research is the identification a normative and technical gap in planning areas influence reservoirs for power generation, understood these as water bodies which an important part supply 
 resources concentrated. In sense, description problem importance considering hydroelectric megaprojects spatial analysis units made; then, determination land carrying capacity p...

For enhancing the regulation performance and efficient operation of pumped storage power plant, this paper proposed to combine a hydro-generator set with full-size converter achieve decoupling control machine grid. On basis model test, characteristics certain pump-turbine had been discussed implication for was highlighted. At same time, modeling side were presented, simulation results showed th...

One of the main challenges in long-term operation planning hydrothermal systems is uncertainties treatment related to inflows hydroelectric plants and their reservoirs. This work proposes a methodology based on Linear Adjustable Robust Optimization allow tractability infinite uncertainty scenarios problem. To assess applicability method, case studies are simulated using real system Brazilian el...

This paper addresses the synchronization and operation of a 140 kVA inverter system connected to main grid as part decentralized microgeneration system. The considerations for supply electrical energy stored in battery banks, mostly photovoltaic origin, involve study details rigid nonlinear system, which parallels generation distribution standards typical hydroelectric thermoelectric plants. Co...

Run-of-the-river hydroelectric dams cause changes in seasonal inundation of the floodplains, and this may cause displacement of semi-aquatic vertebrates present before dam construction. This study evaluated the movement of crocodilians before and after the filling of the Santo Antônio hydroelectric reservoir on the Madeira River in the Brazilian Amazon, which occurred in November 2011. We radio...
