Caracterización de los precios del mercado eléctrico español con modelos ocultos de Markov de entradasalida (IOHMM)
(Sin editorial (Granada, España), 2005-09-16)En este artículo se presenta una metodología novedosa para la caracterización de la serie de precios del mercado eléctrico español mediante el ajuste de modelos ocultos de Markov de entradasalida (IOHMM). La aplicación del ... -
Benchmarking investments under price-cap regulation
(Sin editorial (Ámsterdam, España), 2006-03-06)This paper develops a new methodology for evaluating the combined price and quality performance of new electricity network investments under price-cap regulation. The basic idea is to simulate a large number of possible ... -

Divisible rough sets based on self-organizing maps
(Sin editorial (Calcuta, India), 2005-12-20)The rough sets theory has proved to be useful in knowledge discovery from databases, decision-making contexts and pattern recognition. However this technique has some difficulties with complex data due to its lack of ... -
Coupled electromechanical cost optimization of high speed railway overheads
(Sin editorial (Atlanta, Estados Unidos de América), 2006-05-22)This paper presents a coupled electromechanical optimization of the cost of high speed railway overheads. The proposed electromechanical optimization solves the coupled mechanical and electrical problems by obtaining the ... -
Critically-congested Nash-Cournot equilibria in electricity networks
(Sin editorial (Estocolmo, Suecia), 2007-05-21)Oligopolistic generators behaviour may result in equilibria characterized by critically-congested lines, that is, congested lines such that arbitrarially small generation changes cause them to be not-congested. The nature ... -
Catenary and autotransformer coupled optimization for 2x25kV systems planning
(Sin editorial (Praga, República Checa), 2006-06-22)In the design process of a 2x25kV power supply, the location and sizing of autotransformers and the choice of the catenary type are usually two aspects very closely interrelated. As a result, the number of autotransformers ... -
A mixed ACDC model for railways’ power systems
(Sin editorial (Praga, República Checa), 2006-06-22)A method to study railways’ power supply systems with AC power distribution networks and DC power feeding is presented in this paper. The aim of this work is to obtain a DC model of the whole system in which AC networks ... -

Desarrollo de algoritmos genéticos, de recocido simulado e híbridos para la planificación de un taller flexible
(Sin editorial (Valencia, España), 2006-09-08)El problema del Jobshop ha sido objeto de investigación durante décadas debido a la diversidad de situaciones en las que aparece y a la complejidad computacional que presenta. Debido a esta última no resulta conveniente ... -
Análisis de la relación precio marginal y demanda de electricidad mediante conglomerado
(Sin editorial (Valencia, España), 2006-09-08)El presente artículo analiza la relación entre el precio marginal del mercado de electricidad y la demanda mediante el uso de conglomerados. Se obtienen conglomerados para las muestras conjuntas de precios y demanda mediante ... -
Equilibrado de puestos de cadenas de montaje en producción por lotes
(Sin editorial (Valencia, España), 2006-09-08)En la actualidad la organización productiva de las cadenas de montaje puede orientarse hacia sistemas de tipo mixto o de tipo multimodelo. En esta ponencia se detalla el procedimiento de resolución de este segundo tipo de ... -

An optimization procedure to determine the topology of ac railways power supply networks
(Sin editorial (Pueblo, Estados Unidos de América), 2007-12-05)This paper presents an optimization procedure to determine the topology of AC railways power supply networks: location and type of the substations, catenaries to be used, location of neutral zones and location of ... -
Emission rights allocation criteria
(Sin editorial (Tampa, Estados Unidos de América), 2007-06-24)Contrary to what a naive application of standard economic theory could suggest, correct emission right allocation can be critical in order to assure the economic efficiency of an emission trade system. In this paper, the ... -
Risk-constrained strategic bidding of a hydro producer under price uncertainty
(Sin editorial (Tampa, Estados Unidos de América), 2007-06-24)Price uncertainty faced by generation companies in electricity spot markets is a relevant source of risk. The inherent volatility of price series can have a direct influence on short term operational profits, and therefore, ... -
Statistical dwell time model for metro lines
(Sin editorial (Coimbra, Portugal), 2007-07-25)Traffic simulation models in metro lines are widely used in predictive control algorithms for traffic regulation and robustness analysis of timetables. The simulation results are highly dependent on the uncertainty modelling. ... -
An optimisation-based traffic regulator for metro lines
(Sin editorial (Coimbra, Portugal), 2007-07-25)This paper presents a new traffic regulation model for metro lines based on the optimisation of a cost function along a time horizon. The resulting control actions modify nominal running times and dwell times to compensate ...
