A reduced-order model for simulation of back-to- back start-up of synchronous motors in pumped storage hydropower plants
This paper proposes a reduced-order model for the simulation of back-to-back start-up of synchronous motors in pumped storage hydropower plants aimed at calculating the starting time of the generator-motor set. It is assumed ... -
A review of cross-sector decarbonisation potentials in the European energy intensive industry
The energy intensive industry (EII) is responsible for two-third of industrial carbon dioxide emissions in the EU. It has been recognised by both public and private stakeholders that a far-reaching transformation of these ... -
A Service-Learning Project for Mathematics Education with Spanish Preservice Teachers and Teachers from Rural Schools in Guatemala
Mathematics Education in Teacher Education has served as the framework for an International Cooperation Project between Spain and Guatemala. Since 2016, Spanish preservice teachers have annually drafted a Training Plan for ... -
A short term uncertainty reduction technique for transmission expansion planning based on line benefits
This article provides a novel technique to represent in a reduced, or compact, way short term uncertainty in Transmission Expansion Planning (TEP). Uncertainty reduction is handled by means of "snapshot selection". Instead ... -
A simple rule-based energy management system for off-grid systems
Off-grid systems are systems that are not interconnected with the grid and that congruently operate in islanded mode permanently. In order to operate the off-grid system efficiently, an energy management system (EMS) is ... -
A simplified algorithm to solve optimal power flows in hybrid VSC-based ACDC systems
High Voltage Direct Current systems based on Voltage Source Converters (VSC-HVDC) are increasingly being considered as a viable technology with advantages, above all when using underground or submarine cables for bulk power ... -
A stochastic market-clearing model using semidefinite relaxation
This paper proposes a two-stage stochastic market clearing (SMC) model based on a semidefinite programming (SDP) relaxation. The SMC model aims at determining the day-ahead schedule (DA) and the real-time (RT) balance ... -
A survey of time-of-flight algorithms to determine bone positions in movement
In biomechanical applications where an ultrasound signal is used to determine the position of a specific organ or tissue, like for example a bone, a so-called A-mode ultrasonog- raphy is used. A ultrasonic pulse is generated ... -

A survey on gaussian process extensions in financial time series
El modelado estadístico de series de tiempo financieras ha sido históricamente un foco central de la comunidad investigadora. A su vez, los avances tecnológicos experimentados durante las últimas dos décadas han aumentado ... -
A synthetic index for predicting financial distress in the Spanish rural credit cooperatives sector
Estudio e la posibilidad de predicción del riesgo de quiebra en el sector de las cooperativas de crédito españolas a través de un indicador sintético calculado en base a la información contable de las entidades -
A System Dynamics / Merit Order Pricing model for liberalized power system planning
Este artículo presenta un modelo diseñado para prever la evolución a largo plazo del sistema eléctrico de un país basado en variables exógenas, como los precios internacionales de los productos básicos o las políticas ... -
A theoretical model involving FOUR DIFFERENT USES OF PLAY THERAPY within pediatric psychooncology
Este trabajo presenta un modelo que incluye diferentes estrategias de intervención psicológica con el niño con cáncer, a través del uso del juego terapéutico en contextos de psicooncología pediátrica. -
A tool for computation of electrical losses in wind farms grids
Accurate calculation of electrical losses of wind farm grids is needed in the economic evaluation of wind generation projects. This paper describes a tool for computation of electrical losses in wind farm grids. It makes ... -
A tool for optimal operation and design of batteries and its applications to self-consumption
This paper presents a tool for optimal operation and design of batteries and its applications to self-consumption. The recent improvements in capabilities and costs of battery storage technologies might enable new business ... -

A tool for simulation, analysis and design of underfrequency load-shedding (UFLS) schemes of isolated power systems
Isolated power systems are especially sensitive to generation-load imbalances. The small size, the relatively low inertia, and the comparatively large generation in-feeds make them more vulnerable to frequency instability ...
