Assessing and improving resilience of future transport systems under climate stress: A case study for Spain
The transportation sector is pivotal to global decarbonization but faces growing risks from climate change and energy system vulnerabilities. This paper presents a framework for designing, improving, and assessing the ... -
Renewable capacity investment planning under distribution grid hosting capacity uncertainty via Conditional Value-at-Risk
Electricity distribution grids have been identified as a potential bottleneck for the rapid rollout of distributed generation. This paper assesses the impact of relaxing the hosting capacity (HC) calculation criteria on ... -
A Joint Supply Function Equilibrium Model for the Hydrogen and Electricity Markets
Hydrogen is emerging as a key energy carrier in the global transition toward decarbonization. The production of green hydrogen, derived via electrolysis powered by renewable energy, links hydrogen and electricity markets, ... -
Cross-Border Capacity Remuneration Mechanisms and De-Rating Factors: Determining the Value of Foreign Resources in Regional Markets
Capacity Remuneration Mechanisms (CRMs) in the European Union (EU) are designed to ensure the adequacy of electricity supply by providing financial incentives for power generation capacity. While CRMs have been widely ... -
Economies of scale matter: how refueling infrastructure policy affects the viability of alternative fuel trucks
This study examines the role played by economies of scale in the economic viability of alternative fuel trucks such as battery-electric (BET) and fuel cell electric trucks (FCET). Focusing on the role of infrastructure ... -
Navigating Energy Poverty in Southern and Western Europe: A Comparative Study of Vulnerability Trends in Crisis Years
The recent energy crisis in Europe has intensified energy poverty (EP), driven by skyrocketing energy prices and worsening financial pressures. Furthermore, inefficient housing and unfavorable socio-economic factors ... -
Trigger rules optimization for adaptable electricity distribution planning: untapping the value of flexibility
The rise of intermittent renewable generation and the electrification of energy uses, such as transportation, heating and cooling, and industrial processes are causing grid congestion and connection delays in some countries, ... -
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 ... -
