A benders’ decomposition approach for optimizing the electric system of offshore wind farms
Lumbreras Sancho, Sara; Ramos Galán, Andrés (Norwegian University of Science Technology (NTNU), IEEE PE Norway Chapter (Trondheim, Noruega), 19/06/2011)Optimizing the electric design of an offshore wind farm is a key issue given cost and reliability considerations. The model presented here has been developed to efficiently optimize the electric layout of a wind farm taking ... -
A common risk factor in global credit and equity markets: An exploratory analysis of the subprime and the sovereign-debt crises
Corzo Santamaría, María Teresa; Lazcano Benito, Laura Inés; Márquez Vigil, Javier; Gismera Tierno, Laura; Lumbreras Sancho, Sara (2020-06-02)Este documento investiga la existencia de un factor de riesgo común en todas las clases de activos y áreas geográficas, centrándose en las crisis y los períodos posteriores a la crisis. Este factor tiene implicaciones ... -
A common risk factor in global credit and equity markets: An exploratory analysis of the subprime and the Sovereign-Debt crises
Corzo Santamaría, María Teresa; Lazcano Benito, Laura; Márquez Vigil, Javier; Gismera Tierno, Laura; Lumbreras Sancho, Sara (2020-06-01)This paper investigates the existence of a common risk factor across asset classes and geographical areas, focusing on the crises and post-crisis periods. This factor has important implications for diversification in ... -
A complex-network approach to the generation of synthetic power transmission networks
Espejo González, Rafael; Lumbreras Sancho, Sara; Ramos Galán, Andrés (2019-09-01)The application of complex-network techniques to the analysis of power grids can provide interesting complementary insights into power studies such as the generation of synthetic power grids. Synthetic power grids are ... -
A decentralized solution for transmission expansion planning: getting inspiration from nature
Lumbreras Sancho, Sara; Wogrin, Sonja; Navarro Llevat, Guillermo; Bertazzi, Ilaria; Pereda García, Maria (2019-12-01)Transmission expansion planning is a problem of considerable complexity where classical optimization techniques are unable to handle large case studies. Decomposition and divide-and-conquer strategies have been applied to ... -
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 ... -
Alpha-1 antitrypsin gene variants in patients without severe deficiency diagnosed with pulmonary emphysema on chest CT
Laviña Soriano, Eduardo; Lumbreras Sancho, Sara; Bravo Quiroga, Lara; Soriano Ortiz, Joan B.; Izquierdo Alonso, José L; Rodriguez Gonzalez-Moro, José Miguel (2024-12-31)Introduction: Although pulmonary involvement due to alpha-1 antitrypsin (AAT) deficiency has been widely described, most studies focus on the genotypes causing severe deficiency (< 60 mgdL).Objective: The aim of this study ... -
Analysis of transmission-power-grid topology and scalability, the European case study
Espejo González, Rafael; Lumbreras Sancho, Sara; Ramos Galán, Andrés (2018-11-01)Topological analyses are crucial when assessing network robustness or generating synthetic power grids. In the case of synthetic power grids, topological considerations may be included during the generation process or they ... -

Automatic selection of candidate investments for transmission expansion planning
Lumbreras Sancho, Sara; Ramos Galán, Andrés; Sánchez Martín, Pedro (2014-07-01)This paper deals explicitly with the problem of proposing candidate lines (sometimes referred to as technical alternatives) for Transmission Expansion Planning (TEP). Candidate lines have been traditionally regarded as ... -
