We consider the inclusion of commitment of thermal generation units in the optimal management of the Brazilian power system. By means of Lagrangian relaxation we decompose the problem and obtain a nondifferentiable dual function that is separable. We solve the dual problem with a bundle method. Our purpose is twofold: first, bundle methods are the methods(More)
Long-term hydrothermal generation planning (LTHTP) problems have been traditionally conceived as minimum cost-based optimization models. However, such policy may lead to unacceptable amounts of load curtailment in critical inflow scenarios, which are likely to be avoided. This paper describes a direct approach for the implementation of a Conditional(More)
