Gestión de proyectos internacionales - Programa EMPIR 2014: Una experiencia española
El Centro Español de Metrología (CEM) ha colaborado activamente en la gestión del proyecto europeo EMPIR 14IND14 (2015-2018): “Torque measurement in the MN·m range”. El objetivo de este proyecto era desarrollar nuevos ... -
Explorative spatial data mining for energy technology adoption and policy design analysis
Spatial data mining aims at the discovery of unknown, useful patterns from large spatial datasets. This article presents a thorough analysis of the Portuguese adopters of distributed energy resources using explorative ... -
Vertical load uncertainty at the TD boundary under different spatial DER allocation techniques
Vertical load is the power flow between electrical transmission and distribution networks. In the past, large-scale generators connected to transmission systems supplied consumers connected to lower voltage levels across ... -

Vertical load is the power flow between electrical transmission and distribution networks. In the past, large-scale generators connected to transmission systems supplied consumers connected to lower voltage levels across ... -
Optimal design of off-grid power systems operated by a rolling-horizon strategy: a method to reduce computational requirements
Reducing costs and risks to foster rural electrification in developing countries is one of the major hurdles for researchers, firms and practitioners aiming to develop business with rural minigrids, which are local networks ... -
Evaluación del tratamiento superficial de lámina de cobre para aplicaciones electrónicas
El cobre se ha utilizado durante más de 50 años en la fabricación de placas de circuito impreso (PCB). Estos PCB se producen mediante la laminación de varias capas de preimpregnados de epoxi reforzados con fibra de vidrio ... -
Enhanced brain death diagnosis through teleneurology
Background: Brain death determination requires expertise and in some cases leads to additional medical procedures that may not be available everywhere. It also generates a great amount of distress for patients and their ... -
Sistema inalámbrico de monitorización neurofisológica intraoperatoria (MNIO)
La Monitorización Neurofisiológica Intraoperatoria (MNIO) es una técnica ampliamente utilizada que sirve para evaluar de forma continuada el funcionamiento de estructuras nerviosas en riesgo de lesión durante el acto ... -
Heuristic approaches to size microgrids: a methodology to compile multiple design options
With the aim of maximizing profits of specific business applications, economics, and sometimes reliability and environmental constraints, have been widely guiding developers when designing microgrids. However, mathematical ... -
Consideraciones metrológicas en los requerimientos de exposición a vibraciones en la normativa de seguridad y salud en el trabajo
La normativa relativa a la seguridad y salud en el trabajo es uno de los pilares de la prevención de riesgos laborales. Numerosos aspectos son evaluados por distintas normativas para asegurar la seguridad del personal en ... -
EUniversal: the universal market enabling interface as a way to unlock flexibility solutions for cost-effective management of smarter distribution grids
This paper offers an overview of EUniversal H2020 project which aims to develop and demonstrate a replicable solution for the interaction of the DSO (through the UMEI – Universal Market Enabling Interface) with the new ... -
Proposal and sizing of a molten Salt-to-sCO2 heat exchanger in supercritical solar thermal power plants
Solar Thermal Power Plants (STPPs), based on supercritical CO2 (sCO2) cycles, seem to be a promising alternative to increase the global solar-to-electric efficiency. The most conventional scheme for this technology is a ... -
Stochastic operation of isolated microgrids: aggregating-rule-based optimization versus standard approaches
Stochastic operation of power systems has risen attention of researchers as fluctuating energy sources like renewables are being increasingly integrated into existing grids. Uncertainties can be higher in small power systems ... -
The H2020 project RAYUELA: a fun way to fight cybercrime
As in the case of maieutics, this paper aims to unveil the most important goals and features of the recently funded European project RAYUELA by answering some important questions, such as: why, who, what, how, what the ... -
Simulating spatiotemporal energy technology adoption patterns under different policy designs
Recent studies found that the adoption of distributed energy resources (DER) tends to cluster spatially and temporally which has significant implications for distribution network planning. Currently, residential DER adoption ... -
Assessing electricity tariffs’ costs allocation in Saudi Arabia: upcoming challenges for a needed redesign
Redesigning electricity tariffs is a key need to enable an efficient integration of end users. The process requires moving from the plain volumetric prices still currently in force in most jurisdictions, to a more sophisticated ... -
A method for evaluating frequency regulation in an electrical grid
The first part of this two-part paper proposes a technique that consists in the measurement, through phasor measurement units, of bus frequency variations to estimate the rate of change of regulated power, and in the ... -
Modeling of third party access tariffs and portfolio gas purchases of CCGTs in the self-unit commitment problem
The structure of the operation costs of gas fired units (GFU) in real power systems is much more complex than what standard unit-commitment (UC) models consider in the state-of-the-art formulations. On the one hand, when ... -
Optimal discretization of net head dependency in heterogeneous multi-reservoir hydroelectric systems
Modeling the net head dependency of hydro power plants constitutes a serious challenge from the optimization point of view. One possible approach is to pre-establish a discrete set of representative net heads and to formulate ... -
Achieving active distribution networks through operational and architectural aspects analysis: a methodology for long-term planning
To enable the paved energy transition towards a cleaner and more sustainable living substantial changes are required at the power distribution grid level. Distributed energy resources together with the emerging actors in ...
