Cost Allocation in an Energy Community: A Comparative Assessment of Operational Approaches
Energy communities have become a key instrument for enhancing social impact and accelerating the deployment of renewable energy sources (RES). Nevertheless, the absence of robust economic mechanisms to allocate the costs ... -
Experimental Validation of Synchronous Compensators for Enhancing Grid-Following DFIGs
Modern power systems are facing a drastic reduction in inertia and grid stiffness due to the massive integration of Inverter-Based Resources (IBRs). In this context, grid-following (GFL) converters relying on phase-locked ... -
Spain, India & the EU against a shifting world order: Challenges and opportunities for cooperation
Ante los cambios tectónicos en el orden mundial y el deterioro del multilateralismo global, resulta necesario explorar nuevas asociaciones estratégicas, así como profundizar las ya existentes. Las relaciones bilaterales ... -
Data requirements, models, and simulation of an overvoltage-driven blackout: an academic perspective
At 12:33 on 28th April 2025, a blackout occurred in the Iberian electricity system. Sixty million people lost the electricity supply. This is the first time in the history of the Spanish peninsular electricity system that ... -
Flexible Demand–Driven LCOE Optimization of Off-Grid Data Centers with Hybrid Renewable, Battery, and Hydrogen Systems
This contribution presents an optimization framework for computing the optimal Levelized Cost of Energy (LCOE) of an off-grid data center that incorporates demand flexibility as a decision variable. The total electricity ... -
Sensor de nivel de líquidos en recipientes opacos basado en resonadores con acoplamiento magnetoinductivo axial
En esta comunicación se presenta un sensor de microondas de bajo coste para la detección de nivel de líquidos en recipientes dieléctricos opacos, con especial atención al aceite de oliva. El sistema propuesto se basa en ... -
When flexibility signals interact: Quantifying the interplay of mechanisms for acquiring DSO services
The growing incorporation of distributed energy resources (DERs), together with the electrification of transport, heating and cooling, is making distribution networks more dynamic and more exposed to local congestion and ... -
Asymptotic analysis of the thermal interaction of geothermal boreholes with aquifers valid for all groundwater flow regimes
Heating and cooling needs of buildings represent a significant share of the world’s total energy consumption. To reach a more sustainable energy future, it is crucial to enhance the efficiency of heating, ventilation and ... -
Electricity System Service Costs on the Rise: Is Spain’s Cost Allocation Mechanism Still Fit for Purpose?
System service costs in Spain have increased by more than 400% since 2020, reaching 16.5% of wholesale market value in 2024. These costs are recovered through a uniform volumetric charge on demand, despite being largely ... -
Data-Driven Case-based Grid Segmentation for Local Flexibility Markets
Local flexibility markets have emerged as a promising market-based approach to accommodate the increasing penetration of distributed energy resources in distribution grids in a cost-efficient manner. This paper presents a ... -
Mejorar la orientación STEM como reto del siglo XXI
Las actividades de orientación, tales como, charlas de profesionales, experiencias en entornos de trabajo, sesiones informativas, testimonios, etc. son fundamentales para ayudar a los jóvenes a tomar decisiones eficaces ... -
The Impact of Aggregation Method Choice in GIS-Based Multi-Criteria Decision-Making Techniques for Site Selection of Green Hydrogen Production: A Brazilian Case Study
Renewable hydrogen is key to Brazil’s transition to a carbon-neutral energy system, utilizing its abundant solar and wind resources for large-scale decarbonization. Despite its vast renewable potential, high costs and ... -
Dynamic Analysis of Grid-Forming Control Strategies under High RoCoF Conditions
The increasing penetration of inverter-based resources reduces system inertia, increasing the sensitivity of system frequency to power imbalances and potentially leading to higher rates of change of frequency (RoCoF) during ... -
Beyond Carbon Pricing: Policy-Driven Willingness to Pay for e-Fuels in EU Shipping
The decarbonization of maritime transport requires alternative fuels that are not only technically viable but also economically competitive. We quantify economic competitiveness through the willingness-to-pay (WTP), defined ... -
Mejora del Comportamiento de Convertidores Grid-Following mediante Compensadores Síncronos: Validación Experimental en el LIDER Lab
Los sistemas de potencia modernos enfrentan una reducción drástica de inercia y rigidez de red debido a la masiva integración de Recursos Basados en Inversores (IBRs). En este contexto, los convertidores con seguimiento ... -
Too many or too few? Evaluating AFIR’s distance rule against demand-driven hydrogen refuelling networks
The economic viability of hydrogen fuel-cell trucks (FCETs) depends critically on the levelised cost of hydrogen supply (LCOSH), which falls sharply with station utilization rate. Yet the Alternative Fuels Infrastructure ... -
Demand elasticity under congestion pricing: Evidence from managed lanes in California
Empirical evidence on price elasticities under congestion pricing remains scarce, typically relying on discrete policy changes or low-frequency data that limit identification. Evidence remains extremely limited for managed ... -
AI and Spirituality: Navigating Ethical Implications and Practical Applications
Artificial intelligence (AI) is profoundly transforming human life, extending its influence into relational and spiritual realms. Recent developments illustrate how AI is being integrated into spiritual practices and forms ... -
Integration of green hydrogen generation in the MIBEL, a long-term analysis
Nowadays, one of the major challenges of industry is reaching sustainability and decreasing greenhouse effect emissions. In this decarbonization context, recent studies have analysed the role of hydrogen. Depending on their ...
