Uncovering Hidden Biases in Hydropower: Why Detailed Inflow Data is Crucial for Energy System Optimization Models
Hydropower plays a critical role in balancing highly renewable power systems, yet its representation in energy system optimization models is often constrained by limited availability of high-resolution inflow data. In ... -
MaDIoT 3.0: Análisis de Ataques a la Demanda y Generación Distribuida en un Sistema Eléctrico
Este artíıculo analiza el impacto y la eficacia de los ataques MaDIoT 3.0 en el modelo PST-16, un sistema europeosimplificado. Estos ataques, de carácter novedoso, permiten comprometer de forma simultánea dispositivos IoT ... -
Branches of markoff m-triples with two k-ibonacci components
We study infinite paths of Markoff m-triples, that is, solutions to the generalised Markoff equationx2 + y2 + z2 = 3xyz + m,with m > 0, with at least two k-Fibonacci components. First, we obtain a complete classification ... -
Operational Wildfire Ensembles for Electric Grid Assets: Mapping Burn Probability and Exposure
Wildfires are increasingly affecting electric power systems through two coupled pathways: ignitions initiated by grid assets (e.g., faults, conductor–vegetation contact, arcing) and damage or operational disruption when ... -
Valuation of Regulatory Risk on Pharmaceutical R&D
Geopolitical tensions, supply-chain concerns and policy risk have moved to the forefront of the pharmaceutical industry. This paper develops a real options valuation model of drug R&D that captures sequential clinical ... -
A Comparative Objective Weighting MCDM-GIS Approach to Renewable Hydrogen Production Site Selection: A Spanish Case Study
Deciding on the optimal location for a hydrogen production plant is a complex task that involves multiple factors, including proximity to demand centers, availability of renewable energy resources or existing infrastructure. ... -
Commons-Governed Automation as Material Infrastructure for an Economy for the Common Good
The Economy for the Common Good (ECG) movement proposes reorienting economic activity toward social justice and ecological sustainability. Yet a critical question remains underexplored: what material infrastructure could ... -
Frequency-Constrained UC via Second-Order ODEs with ML Surrogates
This paper proposes a fast and interpretable framework for frequency-constrained unit commitment (FCUC) using machine-learning (ML) surrogates. Unlike prior studies that rely on proprietary system-frequency-response tools, ... -
Sliding Mode Control Techniques for Voltage Source Converters under Low-Voltage Ride-Through Scenarios
The present paper evaluates different sliding mode control techniques for the negative-sequence current injection of voltage source converters under low-voltage ride-through scenarios. Under such scenarios those devices ... -
TDSF-Based Evaluation of Transformer Interactions with VCB, Cable Length, and Neutral Grounding
This paper presents a TDSF-based evaluation of dielectric severity in transformer windings, focusing on transient overvoltages induced by cable–transformer interactions during vacuum circuit breaker (VCB) closing. Unlike ... -
Grid-Forming Converter DC-link Control considering the Primary Energy Source using a Genetic Algorithm
The gradual substitution of conventional synchronous generators by electronic generators raises concerns about the reduction of conventional inertia in electric power systems and the ensuing threat to the stability of those ... -
Analysis of Grid-forming/following STATCOMs and Synchronous Compensators for Grid-following IBRs stability
This paper investigates how different compensating devices can enhance the small-signal stability of the system by means of the phase-locked loop (PLL) in inverter-based resources (IBRs) operating in grid-following mode. ... -
Scalable Complex Orders: How Euphemia Algorithm Improved Scalability while Facilitating Participants Bidding
Euphemia is the algorithm used in the Single Day-Ahead Coupling (SDAC) to clear the European Day-Ahead Market. Scalable Complex Orders (SCOs) were introduced in 2025 to represent generation units fixed costs and technical ... -
Improved Eigenvalue Sensitivity Method for Designing Power System Damping Controllers
Inter-area oscillations are a major challenge for power systems, as they can lead to system instability if they are not damped. To prevent such, restrictions on power transmission over specific lines are often necessary, ... -
Cross-Border Participation in EU Resource Adequacy Mechanisms: Understanding the Contribution 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 economic incentives for power generation capacity. While CRMs have been widely ... -
Playing to Do Research: Exploring the Use of the RAYUELA Video Game to Conduct Prevalence Studies and Risk Factor Analysis of Cyberbullying
This research explores the use of a serious game as an alternative or complementary research tool to surveys and validated questionnaires for studying cyberbullying. A scientifically-based video game was designed, incorporating ...
