A nonlinear programming approach to optimal static generation expansion planning
Ramos Galán, Andrés; Pérez Arriaga, José Ignacio; Bogas Gálvez, Juan (1989-08-01)It is shown how a standard nonlinear programming approach can be applied to solve a sophisticated version of the static optimal mix problem in generation planning. The model presented includes technical minima of thermal ... -
A progressive contingency incorporation approach for stochastic optimization problems
Lumbreras Sancho, Sara; Ramos Galán, Andrés; Cerisola Lopez De Haro, Santiago (2013-05-01)Reliability is a key objective in many optimal design problems. Very often this criterion is incorporated into stochastic optimization problems by introducing contingency evaluation scenarios. This results in a special ... -
A search space reduction method for transmission expansion planning using an iterative refinement of the DC Load Flow model
Ploussard, Quentin; Olmos Camacho, Luis; Ramos Galán, Andrés (2020-01-01)This paper provides a new methodology to compute a reduced but efficient set of candidate lines in a transmission expansion planning (TEP) context. Considering this reduced set of candidate lines should lead to similar ... -
A short term uncertainty reduction technique for transmission expansion planning based on line benefits
Ploussard, Quentin; Olmos Camacho, Luis; Ramos Galán, AndrésThis article provides a novel technique to represent in a reduced, or compact, way short term uncertainty in Transmission Expansion Planning (TEP). Uncertainty reduction is handled by means of "snapshot selection". Instead ... -
