A benefit-based methodology to rank transmission expansion projects
Báñez Chicharro, Fernando; Olmos Camacho, Luis; Ramos Galán, Andrés; Latorre Canteli, Jesús MaríaThis paper proposes a novel methodology to rank transmission expansion projects based on the benefits they provide to the system. The methodology developed estimates the benefits produced by investment projects, and is ... -
A complex-network approach to the generation of synthetic power transmission networks
Espejo González, Rafael; Lumbreras Sancho, Sara; Ramos Galán, Andrés (28/08/2018)The application of complex-network techniques to the analysis of power grids can provide interesting complementary insights to power studies such as the generation of synthetic power grids. Synthetic power grids are ... -

A generation operation planning model in deregulated electricity markets based on the complementarity problem
Rivier Abbad, Michel Luis; Ventosa Rodríguez, Mariano; Ramos Galán, Andrés; Martínez Córcoles, Francisco; Chiarri Toscano, Ángel (Kluwer Academic Publishers (Boston, Estados Unidos de América), 01/01/2001) -
A new tool for bidding hydropower into a competitive market
Ramos Galán, Andrés; Rivier Abbad, Michel Luis; Ventosa Rodríguez, Mariano (01/12/1998)As the electricity supply industry becomes competitive, hydro plant operators need to be able to accurately estimate how much power they can generate at any given time. Computer models are useful in this endeavor. This ... -
A nonlinear programming approach to optimal static generation expansion planning
Ramos Galán, Andrés; Pérez Arriaga, José Ignacio; Bogas Gálvez, Juan (01/08/1989) -
A nonlinear programming approach to optimal static generation expansion planning
Ramos Galán, Andrés; Pérez Arriaga, José Ignacio; Bogas Gálvez, Juan (01/08/1989)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 novel power grid reduction technique for a transmission expansion planning problem using a weighted signed graph model
Ploussard, Quentin; Olmos Camacho, Luis; Ramos Galán, Andrés; Söder, LennartIn Power System, the aim of Transmission Expansion Planning (TEP) studies is to determine which, where, and when new transmission lines should be constructed at the minimum total cost. The large-scale network (around 10 ... -
A progressive contingency incorporation approach for stochastic optimization problems
Lumbreras Sancho, Sara; Ramos Galán, Andrés; Cerisola Lopez De Haro, Santiago (01/05/2013)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 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 ... -

A tight MIP formulation of the unit commitment problem with start-up and shut-down constraints
Gentile, C.; Morales España, German Andres; Ramos Galán, Andrés (01/03/2017)This paper provides the convex hull description of the single thermal Unit Commitment (UC) problem with the following basic operating constraints: (1) generation limits, (2) start-up and shut-down capabilities, and (3) ... -
A two-stage stochastic model for energy contracting decisions of an industrial consumer
Gómez-Villalva García, Emilio; Ramos Galán, AndrésTo encourage industrial consumers to participate more actively in deregulated energy markets, it is necessary to provide them with optimization tools to manage the risk derived from energy price uncertainty. With the risk ... -
Accounting for network energy losses when computing distribution locational marginal prices in a large-scale power system: application to the Spanish case
