Metodologías innovadoras para la difusión en metrología. Escape room virtuales sobre metrología legal y sistema internacional de unidades. Indicadores para el seguimiento de los proyectos
Las nuevas tecnologías han irrumpido en la vida del ciudadano de una manera drástica como consecuencia del COVID. La realización de reuniones virtuales, la digitalización acelerada de actividades que se consideraban casi ... -
Development and commissioning of a hydrogen ion source for the CERN ALPHA experiment
The CERN ALPHA experiment makes precision measurements of antihydrogen atoms held in a superconducting magnetic minimum trap. Recent studies of the antihydrogen spectrum have provided unique tests of fundamental physics, ... -
Detection and properties of voltage impasse regions in the presence of nonlinear static loads
This paper introduces a generic method for detection of Voltage Impasse Region(s) (V IR) that may appear when power system dynamics are represented by a set of differential algebraic equations. The recently introduced V ... -
Small-signal analysis of a microgrid with secondary control including the dynamics of primary control and communication delays
Microgrids (MGs) facilitate the integration of distributed energy resources (DERs) in electrical grids. To coordinate the operation of these DERs, a three-level hierarchical control is commonly used. In general, different ... -
Addressing unfeasibilities of energy storage systems participating in energy and reserve markets
Optimization algorithms formulated to define the joint participation of Energy Storage Systems (ESSs) in energy and reserve markets often lead to unfeasibilities related to the available energy stored in the ESS, particularly ... -
Guaranteeing the provision of primary frequency control services by distributed generation
In this work, a tool for the evacuation of Primary Frequency Control (PFC) service by generators connected to the distribution network is proposed. To achieve this goal, a linear AC Optimal Power Flow (OPF) model with a ... -
Scalability evaluation of a Modbus TCP control and monitoring system for Distributed Energy Resources
Modbus TCP is a communication protocol widely used in industrial applications and to communicate with energy assets such as inverters or data loggers. The communications technologies involved in the management of distributed ... -
A parametric methodology for the assigment of pressure values versus refractive measurement
The 18SIB04 QuantumPascal EMPIR project aims to achieve quantum-based pressure standards. One of the most promising ways of achieving this goal is the use of a Fabry-Perot interferometer for measuring the refractivity of ... -
Uncertainty in mechanical deformation of a Fabry-Perot cavity due to pressure: towards best mechanical configuration
In this paper, a study of the deformation of a refractometer use to achieve a quantum realization of the Pascal is made. First, the propagation of the uncertainty in the measure of pressure due to mechanical deformation ... -
The impact of industrial policymaking on the economics of low-emission technologies: the TRANSid model
Basic materials like steel, cement, aluminium and (petro)chemicals are the building blocks of our industrialised societies, but today their production is highly energy and emission-intensive. Hence, these industries need ... -
Short-term wind power forecasting by a long short term memory ensemble approach
Wind power plants have attracted increasing attention during the last decades due to their environmental and economic benefits. However, the wind resource is inherently unpredictable, bringing important challenges to the ... -
Evaluación de la movilidad de pacientes crónicos complejos mediante dispositivos de seguimiento para su valoración pronóstica
Los Pacientes Crónicos Complejos (PCC) se caracterizan por ser pacientes de edad avanzada con enfermedades limitantes y progresivas, polifarmacia y deterioro funcional, generando una mayor demanda asistencial y un mayor ... -
State-of-energy balancing control with cascaded H-bridge for second-life batteries
Battery energy storage systems (BESS) are fre-quently utilized to support the power grid. Second-Life batteries (SLBs) are considered as a potential solution to reduce the cost of BESS in stationary applications. However, ... -
