Assessment and Experimental Validation of Grid-Forming Inverters’ Capability Counteracting Low-Frequency Oscillations
No full textThe integration of inverter-based resources (IBRs) is reshaping power grid 1
operation by reducing system inertia, which impacts small-signal rotor angle stability and 2
increases low-frequency oscillations (LFOs). While power electronics based Flexible AC 3
Transmission systems (FACTS) have been the primary solution, the shift of IBR control 4
toward grid-forming (GFM) is changing this approach. GFM control inherently provides 5
inertia and affects small-signal stability, but implementing power oscillation damping 6
(POD) algorithms in these inverters presents challenges, particularly regarding active 7
power based ones (POD-P). Although various POD-P solutions are emerging for GFM 8
inverters, few studies evaluate their impact on the GFM device itself and their inherent 9
capabilities, such as inertia and damping. This paper proposes that any design methodology 10
should consider, besides the impact of POD controls on the grid, their effect on the GFM 11
devices properties. It introduces a theoretical framework using the network frequency 12
perturbation (NFP) approach to assess this impact. Additionally, a simple POD-P control 13
method is proposed for GFM controllers, with simplicity as its key advantage. The desired 14
damping effect, along with the absence of impact on other frequency components, is 15
verified through NFP analysis. The theoretical findings are experimentally validated with 16
test bench results.This work is financially supported by the Basque Government under the Grant IT1647-22 511 (ELEKTRIKER research group)

Synergistic effects of Pt-doping in Ni/Al2O3 catalysts for hydrogen storage using benzyltoluene as LOHC
No full textThis study explores Liquid Organic Hydrogen Carriers (LOHCs) like benzyltoluene as a promising alternative for efficient hydrogen storage. In response to the common use of noble metal-based catalyst in the literature, this work focuses on the synthesis of cost-effective Ni-based formulations with small quantities of PGMs. The prepared Ni catalyst exhibited outstanding hydrogenation performance with a hydrogenation yield ∼100 % within 3 h. Furthermore, the incorporation of mall amount (0.5 wt%) of Pt into the catalysts proved to boost the hydrogenation activity due to synergistic Pt–Ni interactions. This study underlines the potential of PtNi bimetallic catalysts as high-performance formulations, contributing to the development of economically viable and efficient catalyst for H2 storage via LOHCs.This research was supported by the University of the Basque Country (UPV/EHU), Basque Government (Project: IT993-16), the Spanish Ministry of Economy, Industry and Competitiveness grant number PDI2020-112889RB-I00, funded by MCIN/AEI/10.13039/501100011033), as appropriate, by “ERDF A way of making Europe”, by the “European Union” or by the “European Union NextGenerationEU/PRTR”, the Fuel Cells and Hydrogen 2 Joint Undertaking (now Clean Hydrogen Partnership) under grant agreement: 101007223
Spout diameter in fine particle conical spouted beds: Assessing the influence of draft tubes by PTV
No full textThe spout diameter is an essential parameter for designing spouted bed contactors, as it conditions the gas–solid contact and heat and mass transfer rates. Several correlations have been proposed in the literature to estimate the spout size, but they do not provide accurate results in beds made up of fine particles, especially when they are equipped with open-sided draft tubes. Accordingly, the spout–annulus interface has been determined by means of Particle Tracking Velocimetry (PTV) and the spout shape has been delineated under different operating conditions in fountain confined conical spouted beds of varying geometric parameters. The air inlet diameter and gas velocity, as well as the aperture ratio of the open-sided draft tubes, are the parameters of greatest influence. Accordingly, a new correlation has been proposed, which allows predicting accurately the spout size in beds without draft tube, as well as those equipped with open-sided ones.This work has received funding from the grant PID2022-139454OB- I00 funded by MCIN/AEI/10.13039/501100011033 and the grants IT1645 − 22 and KK − 2023/00060 funded by the Basque Government, Spain.

Ellipse at 0° and 90° comparison at low Reynolds numbers for time-resolved Shake-The-Box measurements
No full textVortex shedding dynamics and aerodynamic forces of an ellipse of aspect ratio of 0.67 are studied at 0 and 90 relative to the flow across a Reynolds number range of 550–5500. Using time-resolved Shake-The-Box measurements, the evolution of vortex structures is studied together with lift and drag coefficients, Strouhal numbers, and wake characteristics. At 0, the flow remains more attached, leading to lower drag, lower lift fluctuations, and higher shedding frequencies, as indicated by elevated Strouhal numbers. In contrast, at 90, the ellipse behaves as a bluff body, exhibiting stronger separation, higher drag, greater lift fluctuations, and lower shedding frequencies. Proper orthogonal decomposition analysis reveals key vortex distances, showing how separation and wake evolution change with increasing Reynolds number. Additionally, the transition from laminar to turbulent wake structures is observed, with three-dimensional instabilities affecting vortex coherence at high Reynolds numbers. The findings provide insight into the effects of geometry and Reynolds number on vortex-induced forces.The authors are grateful for the support provided by LaVison and specially thank Lutz Fiedler and Dr. Dirk Michaelis.

Are you talking to me? How the choice of speech register impacts listeners’ hierarchical encoding of speech
No full textAvailable online 31 March 2025Speakers accommodate their speech to meet the needs of their listeners, producing different speech registers. One such register is L2 Accommodation (L2A), which is the way native speakers address non- native listeners, typically characterized by features such as slow speech rate and phonetic exaggeration. Here, we investigated how register impacts the cortical encoding of speech at different levels of language integration. Specifically, we tested the hypothesis that enhanced comprehension of L2A compared with Native Directed Speech (NDS) involves more than just a slower speech rate, influencing speech processing from acoustic to semantic levels. Electroencephalography (EEG) signals were recorded from Spanish native listeners, who were learning English (L2 learners), and English native listeners (L1 listeners) as they were presented with audio- stories. Speech was presented in English in three different speech registers: L2A, NDS, and a control register (Slow- NDS) which is a slowed down version of NDS. We measured the cortical encoding of acoustic, phonological, and semantic information with a multivariate temporal response function analysis (TRF) on the EEG signals. We found that L2A promoted L2 learners’ cortical encoding at all the levels of speech and language processing considered. First, L2A led to a more pronounced encoding of the speech envelope. Second, phonological encoding was more refined when listening to L2A, with phoneme perception getting closer to that of L1 listeners. Finally, L2A also enhanced the TRF- N400, a neural signature of semantic integration. Conversely, L2A impacted acoustic but not linguistic speech encoding in L1 listeners. In contrast, slow- NDS altered the cortical encoding of sound acoustics in L1 listeners but did not impact semantic or phonological encoding. Taken together, these results support our hypothesis that L2A accommodates speech processing in L2 listeners beyond what can be achieved by simply speaking slowly, impacting the cortical encoding of sound and language at different abstraction levels. In turn, this study provides objective metrics that are sensitive to the impact of register on the hierarchical encoding of speech, which could be extended to other registers and cohorts.This research was supported by a Doctoral Fellowship (LCF/BQ/DI19/11730045) from the “La Caixa” Foundation (ID 100010434), the Cognition and Natural Sensory Processing Initiative (CNSP), a travel scholarship supported by mBrainTrain, and a Scientific Exchange grant from the European Molecular Biology Organization (EMBO, number 9996) awarded to G.P.
