An enhanced screening curves method for considering thermal cycling operation costs in generation expansion planning
(2013-11-01)Generation capacity expansion trends have clearly evolved in the last decades. In the present context, renewable generation technologies are expected to reach large penetration levels. Among other effects, these technologies ... -
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 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 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 exploratory study of fibre microplastics pollution in different process stages of salt production by solar evaporation in Spain
(2024-06-15)Microplastics are a pollutant of growing concern. Several studies have found microplastics in table salt worldwide in the last decade, although most have focused on already prepackaged salt. To the best of our knowledge, ... -
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 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
(18/07/2018)En este artículo mejoramos la hasta ahora mejor cota inferior para el máximo número de bisectores sobre los posibles conjuntos de 32 puntos en el plano. Para ello, damos una cota inferior recurrente para el máximo número ... -
An Improvement of the Lower Bound on the Minimum Number of <=k-Edges
(01/03/2021)En este artículo se mejora la cota inferior del mínimo número de <=k-edges para conjuntos de n punros del plano en posición general, cuando k está cerca de n/2. Como consecuencia, se mejora la actual mejor cota inferior ... -
An induction motor model for system frequency response models
(2017-11-01)This paper presents a simple induction motor (IM) model for system frequency response (SFR) simulations. SFR simulations are widely used to analyze frequency stability of small isolated power systems. Isolated power systems ... -
An integrated approach to simulate the impacts of carbon emissions trading schemes
(2009-12-01)Article from Special Edition 2009: Climate Change Policies after 2012 The present paper aims to reliably depict the impact of the European Union Emissions Trading Scheme (EU ETS) on Spain under different assumptions about ... -
