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 ... -
A Multi-Stage Strategy for Harnessing Congestion Management Services from Industrial Hubs in Local and System-level Markets
This paper introduces a multi-stage coordination model incorporating industrial hubs, distribution system operators (DSOs), and the transmission system operator (TSO) into separate stages within a hierarchical optimization ... -
Decentralized Energy Management for Rural Communities: A Blockchain-Based Virtual Power Plant with AI-Driven Forecasting
This paper presents the design and evaluation of RuralVPP, a decentralized Virtual Power Plant (VPP) architecture designed for rural energy communities. The system integrates ten semi-autonomous municipalities into a ... -
Distributionally Robust Games for Data Center Demand Response Coordination based on CPU utilization and Quality of Service
In light of the soaring energy demand of data centers (DC), cloud providers seek effective solutions to reduce power consumption and ease grid stress. Dynamic voltage and frequency scaling (DVFS) could reduce CPU power ... -
Generation and transmission expansion planning considering FTRs as a long-term regulatory risk-hedging and coordination mechanism
Due to the deregulation process and the changes that the power system is undergoing in its transition to a decarbonised, sustainable, more integrated, one, power system stakeholders need instruments to manage the increasing ... -
Planificación de Inversiones en Sistemas de Distribución Bajo Incertidumbre en el Contexto de la Transición Energética: Un Enfoque Multiescenario
La transición energética plantea importantes retos para la planificación de los sistemas de distribución eléctrica. Las empresas distribuidoras deben tener en cuenta elementos que aportan incertidumbre, entre las que se ... -
Planning Framework for Distribution System Investments Under Energy Transition Uncertainty: A Multi-Scenario Approach
The energy transition presents significant challenges to the planning of electrical distribution systems. Distribution companies must take into account a variety of uncertainties, including the adoption of electric vehicles, ... -
The blackout of the Iberian Peninsula on April 28, 2025
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 ... -
Techno-economics evaluation of electrolyser technologies: multicriteria decision making with SmartGridEval
The global landscape of hydrogen use has witnessed significant developments. Its high energy density and ability to be stored for an extended period make it an excellent fuel for storage systems. Green hydrogen, produced ...
