Emerging innovations in health metrology for diagnostic imaging
The Spanish National Metrology Center (CEM) is dedicated to advance the understanding of the essential role of measurements in the healthcare sector. CEM has created a laboratory in healthcare metrology to ensure the ... -
Probabilistic functional forecasting of Residual Demand Curves in electricity markets
Residual Demand Curves (RDCs) in electricity markets represent the market-clearing price as a function of the energy traded. Being able to generate accurate scenarios of these curves is critical for market agents' strategic ... -
A decentralized business model for integrating energy hubs into flexibility markets within renewable-based smart grids
This paper presents a bi-level model enabling energy hubs to release all their flexible capacities according to the price pulse in real-time flexibility markets. The Alternating Direction Method of Multipliers (ADMM) is ... -
Building bidding curves for an EV aggregator via stochastic adaptive robust optimization
This paper proposes a stochastic adaptive robust optimization approach to build the bidding curves of an aggregator in charge of a set of electric vehicles participating in the day-ahead electricity market. These bidding ... -
Estrategia para la información y difusión del patrimonio geominero español mediante técnicas de realidad virtual portable en dispositivos móviles
La realidad virtual (VR) es la una herramienta muy útil para fomentar la participación y la motivación de los estudiantes en la educación, y por ende divulgar y difundir el patrimonio tangible, entre otros. En este trabajo, ... -
Impact of uncertain data in robust optimal bidding of RVPP in energy and reserve markets
Different probability distributions yield different outcomes of optimization problems under uncertainty such as the optimal bidding problem of RES-only Virtual Power Plant (RVPP). Robust Optimization represents uncertainties ... -
Tools for Reliability and Resilience-oriented planning and operation of hybrid ACDC power systems
The impact of extreme events on power system operation is a growing concern, and planning and operation of hybrid ACDC power systems should account for resilience. This paper presents a framework for reliability and ... -
Understanding generator droop voltage control
Power park modules are required by network codes to provide droop voltage power control at the point ofconnection (POC) to the grid. This paper contains a thorough analysis of the droop voltage control scheme of power park ... -
Exploring a 2030 nearly 100% renewable Spanish electricity system from a capacity-mix adequacy perspective
Nowadays, the increase in gas prices in Europe is fostering the penetration of renewable generation in electricity systems and pressing countries to accelerate the energy transition. It is then arguable whether goals on ... -
Integrating third-party flexibility resources into distribution networks: a quantitative assessment on the interactions of network tariffs and local markets
This paper explores innovative approaches to enhance the use of flexibility for electrical distribution networks by integrating time-of-use tariffs and local markets for DSO services. The study presents an analysis through ... -
The need for system balance restoration after congestion management: an examination of Iberian congestion management markets
The Iberian electricity markets use a dedicated congestion management market to address network constraint violations arising from zonal day-ahead market dispatches. This market operates in two phases: the first phase ... -
The effect of seatbelt pre-tensioners and load limiters in the occurrence of MAIS 2+ and MAIS 3+ abdominal injuries in real-world frontal crashes
Abdominal injuries are still frequent in motor vehicle crashes despite advancements in automotive safety and improvements to restraint systems. Pre-tensioners and load limiters have been incorporated into newer vehicles ... -
Unveiling energy poverty in Southern Europe: indicators, vulnerability factors, and policy implications
This paper presents a quantification of energy poverty in Spain, Italy and France, using five different indicators, and a comparative analysis of the energy poverty situation in these three European countries between 2017 ... -
Assessing the tensile and flexion behavior of the neck of the PIPER pediatric human body model
As there are not contemporary test data assessing the actual neck loads of pediatric humans using CRS in high-speed impacts, computer models of pediatric occupants can be considered an alternative method to complement dummy ... -
A bi-level framework to analyse the use of FTRs as a long-term risk hedging instrument in the European electricity context
A large portion of Renewable Energy Sources generation investments occurs in remote areas, which are normally weakly connected to the rest of the system. Hence, relevant congestion arises in the network linking these areas ... -
The correlations of uncertainties in strategic energy planning models: the impact of fossil fuel prices on renewable energy deployment in Spain
In the face of the global climate crisis, countries worldwide are striving for climate neutrality, necessitating a shift from fossil fuels to renewable energy sources. This energy transition faces deep uncertainties, ... -
A unit commitment model to represent real-size multi-area power systems in the medium term on an hourly basis: Energy storage, fuel contracts, and third-party access management
The deployment of new generation and storage technologies in modern power systems and their increase in interconnection capacities entails a paradigm change in operational trends. Accordingly, energy models require detailing ... -
Synchronous Compensators considering reactive power for PLL stability improvement and Short-Circuit Ratio evaluation
This paper examines the impact of Synchronous Compensators (SC) on the stability of grid-following Inverter-Based Resources (IBRs), with a particular focus on the role of reactive power. Full-order simulation models of a ...
