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 ... -
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 ... -
Generator load profiles estimation using artificial intelligence
(Sin editorial (Kaohsiung, Taiwan), 2008-01-28)The security criteria of a power system require that branch power flows and bus voltages are within their limits, not only in normal operating conditions but also when any credible contingency occurs. In the Spanish ... -

A variable no-load voltage scheme for improving energy efficiency in DC- electrified mass transit systems
(Sin editorial (Colorado Springs, Estados Unidos de América), 2014-04-04)Railway mass transit systems like subways play a fundamental role in the concept of sustainable cities. In these systems, the amount of passengers strongly fluctuates along the day. Hence, in order to provide a proper ... -
Highly sensitive dielectric resonator sensor for liquid characterization
(Universidad de Málaga (Málaga, España), 2020-12-31)This article describes a novel 2 GHz dielectric resonator sensor (DRS). The dielectric resonator is made of ceramic material and is fed by a microstrip transmission line, using the aperture-feeding method. The sensor shows ... -
A Machine Learning approach for the validation and optimization of permittivity mixing rules for binary liquids
(Universidad de Extremadura; Union Radio-Scientifique Internationale (Cáceres, España), 2023-12-31)This paper presents the application of Support Vector Regressor models trained with glycerin-water mixture signals from a Dielectric Resonator sensor. Each signal is labeled with a concentration considered. The performance ... -
A new method for efficient transmission losses allocation in electricity markets without losses consideration in the dispatch
(Universidad de Shanghái Jiao Tong (Shanghai, China), 2024-05-24)Several electricity markets around the world have adopted a single-node dispatch model that does not account for transmission losses. This leads to efficiency losses as the merit order can change significantly. Marginal ... -
Islanded operation of distribution grid with high penetration of renewable energy sources
Renewable energy sources are being connected not only to transmission but also to distribution grids. Medium voltage distribution grids are meshed grids that are operated radially. Their reliability is determined by their ... -
Banking on mobiles. The role of digital epidemic effects and mobile money regulation in accelerating the uptake of financial services
Despite the accelerated mobile money adoption in emerging countries, financial inclusion levels remain well below the developed world, especially when advanced financial inclusion is considered. We argue that the adoption ... -
Climate-related credit risk: Rethinking the credit risk framework
Climate change poses a significant financial risk to economic agents, as well as a potential systemic risk threat due to uncertainty and non-linearity of the transition risks to a zero-carbon economy. This article conducts ...
