recommendations! Published in 2025 at "Scientific Reports"

DOI: 10.1038/s41598-025-91699-1

Abstract: This paper introduces a Reinforcement Learning (RL)-based Power System Stabilizer (PSS) with a Deep Deterministic Policy Gradient (DDPG) algorithm for rotor angle stability. The proposed stabilizer uses scaled values of the generator’s accelerating power, a… read more here.

DOI: 10.1109/tpel.2023.3267624

Abstract: Grid-forming converters (GFCs) usually operate in parallel to supply power to unknown loads. Nevertheless, unknown loads may lead to overcurrent, causing parallel GFCs to enter the current saturation mode (CSM). The steady-state angle stability of… read more here.

DOI: 10.1109/tpwrs.2024.3364532

Abstract: The effects of fast frequency response (FFR) on rotor angle stability have predominately been established by examining the oscillatory behavior of synchronous generators (SGs). What remains largely unexamined, however, is the effect that FFR has… read more here.

DOI: 10.1371/journal.pone.0177238

Abstract: Purpose To compare intraoperative angle stability and postoperative outflow of two ab interno trabeculectomy devices that excise the trabecular meshwork with or without active aspiration and irrigation. We hypothesized that anterior segment optical coherence tomography… read more here.

DOI: 10.35848/1882-0786/abd9ff

Abstract: We propose a dual-band metamaterial absorber (MA) based on a stereo resonant structure. The unit cell of the proposed MA is composed of double metallic rings with a rampart on each ring into a dielectric… read more here.
