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 benefit-based methodology to rank transmission expansion projects

Báñez Chicharro, Fernando; Olmos Camacho, Luis; Ramos Galán, Andrés; Latorre Canteli, Jesús María

This 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 binary differential evolution algorithm for airline revenue management: a case study

Yazdi, Amir Karvassi; Kaviani, Mohamad Amin; Hanne, Thomas; Ramos Galán, Andrés (27/02/2020)

In the current highly competitive airline market, many companies have failed due to their low revenue rates. For this reason, many of them have to develop strategies to increase their revenue. In this study, we develop ...

A complex-network approach to the generation of synthetic power transmission networks

Espejo González, Rafael; Lumbreras Sancho, Sara; Ramos Galán, Andrés (01/09/2019)

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 ...

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, Lennart

In 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 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 (01/01/2020)

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 ...
