An entry-exit gas system model: application to the Iberian natural gas market
Since the promulgation of the Third Energy Package by the European Commission, relevant efforts have taken place to harmonize country-level regulatory frameworks and constitute the Single natural gas market. One of the ... -
An equilibrium approach for modeling centralized and behind-the-meter distributed generation expansion
(2020-07-01)Power systems will face important structural changes in the near future due to the empowerment of consumers, who may resort on self-consumption, and reduce their purchases of electricity from the grid. The avoided costs ... -
An equilibrium approach for modeling centralized and distributed generation expansion planning
This paper proposes an equilibrium approach for modeling the centralized and distributed generation (CG and DG respectively) expansion planning, by representing the operation and investments decisions of both the traditional ... -
An estimation of fuel demand elasticities for Spain: an aggregated panel approach accounting for diesel share
(2015-01-01)In this paper, an econometric analysis of transport fuel demand elasticities is presented for Spain, for the period 2000 to 2007, giving emphasis to the diesel share of the road transport fleet. Estimation results show a ... -
An estimation of fuel demand elasticities for Spain: an aggregated panel approach accounting for diesel share
(Universidad Pública de Navarra (Pamplona, España), 2012-01-26)In this paper an econometric analysis of transport fuel demand elasticities is presented for Spain, based on aggregate panel data. A particular emphasis is given to the impact of diesel share on all transport fuels demand. ... -
An estimation of the economic and environmental benefits of a demand-response electricity program for Spain
(2016-10-01)The evolution towards a more sustainable electricity system will definitely require a stronger role of demand. For example, Demand Response (DR) programs allow consumers to manage their loads in response to signals that ... -
An ex-post analysis of the effect of renewables and cogeneration on Spanish electricity prices
(2011-12-01)Growing concerns about climate change and energy dependence are driving specific policies to support renewable or more efficient energy sources such as cogeneration in many regions, particularly in the production of ... -
An experimental and numerical study on the smoke layer growth and movement within large-volume spaces : atrium fires
(2015)Esta tesis se centra en el estudio de incendios en atrios. Para ello, se presentan 27 nuevos ensayos experimentales de incendio en un atrio a escala real, así como una serie de modelos numéricos CFD (Computational Fluid ... -
An expert system for transmission line back-up protection
(Sin editorial (Montpellier, Francia), 1994-09-05)The paper describes an expert system that provides back-up protection for power transmission lines. The expert system evaluates the best possible protection response if the main-protection andor its associated circuit ... -
An extended metric for the analysis of power-network vulnerability: the line electrical centrality
Power networks are highly vulnerable to deliberate attacks. Whilst power-network design usually considers the protection of the system against networkcomponent failure, it does not consider the protection against deliberated ... -
An extended metric for the analysis of power-network vulnerability: the line electrical centrality
(Institute of Electrical and Electronics Engineers Power and Energy Society; Politecnico di Milano (Milán, Italia), 2019-06-23)Power networks are highly vulnerable to deliberate attacks. Whilst power-network design usually considers the protection of the system against networkcomponent failure, it does not consider the protection against deliberated ... -
An heuristic approach for the study of the Total Demand of Commercial Vehicles
(2020)El proyecto consiste en la enumeración de las técnicas utilizadas para el estudio de la Demanda Total de Vehículos Comerciales. Tomando un visión heurística, dentro del trabajo se puede observar la implementación de distintas ... -
An Ignatian Journey of the Cross: Exercises in Discernment
(The Liturgical Press (Collegeville, MN, Estados Unidos de América), 15/12/2015)Un libro de oración, ejercicios espirituales a partir de un relieve de bronce para introducir en el arte del discernimiento ignaciano. -
An impedance-based CT saturation detection algorithm for bus-bar differential protection
(2001-10-01)This paper presents an algorithm for CT saturation detection based on the measurement of the power system source impedance seen from the relay location. The algorithm estimates this source impedance using a short-data ... -
An improved DAQ-based method for ferrite characterization
(2017-09-01)In this paper, we propose an improved version of the classical volt-amperometric measurement method for the characterization of magnetic hysteresis and losses in soft magnetic cores. Using an appropriate circuital solution ... -
An improvement in the efficiency of olive pomace oil extraction using an optimal pooling decision model
(2013-12-01)When olives are harvested, local presses dispose of olive husk, the residue of the pressing process, transporting it to Olive Waste Management Centres (OWMC). Once there, the husk is emptied into pools to be classified, ... -
An improvement of the lower bound on the maximum number of halving lines in planar sets with 32 points
En este artículo mejoramos ligeramente la hasta ahora mejor cota inferior para el máximo número de bisectores sobre los posibles conjuntos de 32 puntos en el plano -
