RESUMO

This work is concerned with the Short-Term Hydrothermal Scheduling of hydrodominated power systems. The problem formulation includes the representation of system operational constraints such as the hydraulic coupling between hydro plants in cascade and the transmission limits in the electric network. In order to allow the problem to be decomposed into hydraulic and electric subproblems, a linear-quadratic penalty approach is applied to enforce the coupling between hydro and electric variables. As a result, the natural network flow structure of the problem is fully exploited through special-purpose network flow algorithms. The model works with multiobjetive analysis and allows the definition of several scenarios, necessary during the decision processo The technique has been tested in a 440 KVsubsystem of the main interconnected Brazilian power system
