Bridging the Energy Poverty Gap: Evaluating the Impact of Shallow Renovations and Micro-Efficiency in Spain
Low-income households face severe energy affordability issues due to poor housing quality. To fight this problem, Spanish public administrations and NGOs have collaborated with the Naturgy Foundation's Energy Rehabilitation ... -
From Consumers to Participants: A Framework for the design of engaging apps to foster participation in the Electricity System
The active involvement of citizens in energy markets is critical for advancing the energy transition, yet most digital tools fail to engage users beyond superficial interaction. This paper presents a modular framework for ... -
Modeling Membrane Degradation in PEM Electrolyzers with Physics-Informed Neural Networks
This study introduces the first application of Physics-Informed Neural Networks (PINNs) to model membrane degradation in proton exchange membrane (PEM) electrolyzers, which are essential for sustainable hydrogen production. ... -
Fully decentralised multi-agent hierarchical control of a hybrid AC-DC microgrid based on event-triggered consensus
The continuous growth of distributed renewable energy resources in medium and low-voltage networks supports the case for a distributed architecture for electricity supply relying on microgrids. Whereas decentralised ... -
Distribution system operator services: A comparative assessment of multi-product co-optimisation for congestion management and voltage control using a local flexibility market
The increasing penetration of distributed energy resources (DERs) into distribution networks poses significant planning and operational challenges in power systems, particularly in terms of local congestion mitigation and ... -
The (Hopefully) Enlightening Blackout in Spain: Questions and Lessons for the Future
The impact of the April 28th blackout in the Iberian Peninsula went well beyond its immediate economic effects. From the outset, different interest groups began to speculate (in their favor) not so much on the causes of ... -
Assessing Green Hydrogen Support Mechanisms in Coupled Electricity and Hydrogen Markets
Green hydrogen is a promising alternative to decarbonizing hard-to-abate sectors, but its development faces regulatory, economic, and operational challenges. In the EU, strict criteria on additionality, temporal, and ... -
Impact on transient stability of self-synchronisation control strategies in gridforming VSC-based generators
Grid-forming voltage source converters (GFM-VSCs) are emerging as a solution for integrating renewable energy resources (RERs) into power systems. GFM-VSCs need a selfsynchronisation strategy to ensure that all converters ... -
Promoting efficiency with neutral operationalcapital incentives under large uncertainty: A comparison of electricity distribution remuneration schemes
Decarbonization of the energy sector involves the proliferation of decentralized renewable generation, and the electrification of energy uses, such as transportation, heating and cooling, and industrial processes that ... -
Uncertain Decision Making: A Cooperative Agent Model For Flexible Renewable Energy Comunities
The paper proposes an innovative model for integrating energy communities within urban districts according to the smart cities paradigm. The approach developed contemplates the proactive participation of members of an ... -
Preliminary design of S-CO2 turbomachinery and its influence on the performance of an integrated solar combined cycle
Supercritical CO2 power cycles emerge as the next-generation standard for Concentrated Solar Power technology mainly due to their high efficiency and reduced footprint. This study investigates the role of the S-CO2 ... -
Integrating energy communities into the electricity market: overcoming barriers and enhancing flexibility in Spain, Italy, and Greece
The integration of energy communities into existing electricity markets is essential for decentralizing energy systems, decarbonizing electricity production, and enhancing consumer engagement. This paper analyses the ... -
Investigating inclusion of linear sensitivity factors in analytical frequency constrained unit commitment formulation
As power systems transition towards cleaner energy sources and reduce reliance on conventional generation sources, power systems become increasingly vulnerable to frequency instability following large disturbances due to ... -
Enhancing AC Line Emulation controls for improved inter-area oscillation damping and application to Multi-Terminal DC Grids
The integration of High Voltage Direct Current (HVDC) systems into modern power systems offers opportunities to enhance grid resilience through advanced functionalities such as AC line emulation. By emulating AC line ... -
Improving Novelty and Diversity of Nearest-Neighbors Recommendation by Exploiting Dissimilarities
Neighborhood-based approaches remain widely used techniques in collaborative filtering recommender systems due to their versatility, simplicity, and efficiency. Traditionally, these algorithms consider similarity functions ... -
Emergent phenomena in computation: from enthropy to artificial consciousness?
This talk will explore how computing provides a privileged window onto emergence—the phenomenon whereby novel, irreducible properties arise from simple interactions. We begin by clarifying key concepts: synergy, patterns, ... -
Analysis of the New Portuguese and Spanish NECPs using CEVESA market model
The recent updates of the National Energy and Climate Plans (NECPs) for Portugal and Spain have some significant changes compared to the previous 2019 versions, especially for the Portuguese side where a greater demand and ...
