Comparative small-signal evaluation of advanced grid-forming control techniques
Unamuno, Eneko; Barrena, Jon Andoni (Elsevier B.V., 2022)This paper presents the small-signal modelling and analysis of the most recent grid-forming control techniques, namely the matching control (MC) and the dispatchable virtual oscillator (dVOC). These are compared to more ... -
Current References Limitation Method Considering Voltage and Current Maximums for STATCOMs Providing Simultaneously Reactive Power and Current Harmonics
Abad, Gonzalo; Unamuno, Eneko (IEEE, 2022)This article focuses the analysis on a static synchronous compensator (STATCOM) that operates simultaneously providing reactive power and several current harmonics of different frequencies (active power filter or active ... -
Development and Comparison of Rule- and Machine Learning-Based EMS for HESS Providing Grid Services
Unamuno, Eneko; CABEZUELO ROMERO, DAVID (IEEE, 2024)In this paper, a smart machine-learning-based energy management system (MLBEMS) is developed for a hybrid energy storage system (HESS). This HBESS consists of batteries with high-energy (HE) and high-power (HP) characteristics, ... -
Droop control operation strategy for advanced DC converter-based electrical railway power supply systems for high-speed lines
Unamuno, Eneko; Barrena, Jon Andoni (Elsevier Ltd., 2022)Advanced DC converter-based electrical railway power supply systems are very promising power supply configurations for the electrification of high-speed lines. Their full controllable converter-based traction substations ... -
Dual Inertia-Emulation Control for Interlinking Converters in Grid-Tying Applications
Paniagua Amillano, Julen; Unamuno, Eneko; Barrena, Jon Andoni (IEEE, 2021)Electric grids are undergoing several changes, mostly driven by the replacement of classical highly-inertial generators by converter-interfaced generation and storage systems. This entails the reduction of inherent inertia ... -
Equivalence of primary control strategies for AC and DC microgrids
Unamuno, Eneko; Barrena, Jon Andoni (MDPI, 2017)Microgrid frequency and voltage regulation is a challenging task, as classical generators with rotational inertia are usually replaced by converter-interfaced systems that inherently do not provide any inertial response. ... -
Hybrid ac/dc microgrids. Part I : Review and classification of topologies
Unamuno, Eneko; Barrena, Jon Andoni (Elsevier, 2015)Microgrids have been widely studied in the literature as a possible approach for the integration of distributed energy sources with energy storage systems in the electric network. Until now the most used configuration has ... -
Hybrid ac/dc microgrids. Part II : Review and classification of control strategies
Unamuno, Eneko; Barrena, Jon Andoni (Elsevier, 2015)Microgrids are envisioned as one of the most suitable alternatives for the integration of distributed generation units in the utility grid, as they efficiently combine generation, energy storage and loads in the same ... -
Power Capability Boundaries for an Inverter Providing Multiple Grid Support Services
Unamuno, Eneko; Bilbao Ortega, Aitor (MDPI AG, 2020)It is getting more common every day to install inverters that o er several grid support services in parallel. As these services are provided, a simultaneous need arises to know the combined limit of the inverter for those ... -
Second-order Filter-based Inertia Emulation (SOFIE) for Low Inertia Power Systems
Unamuno, Eneko; Barrena, Jon Andoni (IEEE, 2024)The massive integration of power electronic converters into the power grid has led to a decrease in the mechanical inertia of power systems, causing an increase in the rate of change of frequency (RoCoF) that may lead to ... -
Stability tool for electric power systems with a high penetration of electronic power converters
Serrano Jimenez, Daniel; Unamuno, Eneko; Barrena, Jon Andoni (Elsevier B.V., 2022)The increasing use of electronic converters is making possible the development of more sustainable, efficient, and reliable electric power systems, but it is also introducing new challenges that need to be addressed.
