Biomass top-cycle CHP with hightemperature heat pump coupling: economic insights for industrial decarbonization
Over half of the final energy consumed by the European industrial sector relied on carbon-emitting fuels in 2022. Biomass-based cogeneration technologies can efficiently adjust to varying industrial electricity and heat ... -
The effect of seatbelt pre-tensioners and load limiters in the occurrence of MAIS 2%2B and MAIS 3%2B 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 ... -
The role of contracts on a joint Cournot equilibrium for hydrogen and electricity markets modeling
Volatility in gas and electricity prices and the aim of the European Commission for decarbonizing the economy have led to a reform in the European electricity market and boosting hydrogen production. As it is well known, ... -
The behind-the-scenes story of 2022 energy and inflationary crises: data, experiences and opinions of Spanish vulnerable households
The 2022 Russian invasion of Ukraine has caused a profound economic impact in Europe. In this context of energy and inflationary crises, the EU and its Member States implemented different mitigation strategies.However, ... -
Balancing socio-political acceptance and economic efficiency of electricity price signals for residential end users: lessons learnt from the pioneering Spanish experience
The decarbonization of power systems would be more efficient if, among other developments, it would be possible to achieve a significant activation of electricity end users.But the political unwillingness to fully expose ... -
Prueba ilícita versus prueba irregular. distorsiones en la apreciación de la prueba como regla de conducta procesal
El documento analiza las diferencias entre prueba ilícita y prueba irregular en el derecho tributario. La prueba ilícita implica la vulneración de derechos fundamentales, mientras que la irregular solo viola normas procesales ... -
Addressing intra-area oscillations and frequency stability after DC segmentation of a large AC power system
En las últimas décadas, diversos acontecimientos han puesto de manifiesto que las oscilaciones electromecánicas constituyen un grave problema para los grandes sistemas eléctricos de corriente alterna (CA) interconectados. ... -
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 ...
