Improved Islanding Detection With h‐EXPO‐SV ML Algorithm Supporting Positive Sequence Impedance Angle in an Active Distribution System

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
The proposed heuristic expo support vector (h‐EXPO‐SV) machine learning algorithm successfully differentiates between islanding and non‐islanding events, which helps to prevent avoidable DG malfunctions. ABSTRACT Islanding detection has become a serious concern due to the extensive integration of renewable energy sources with the main grid.

A Bi‐GRU–Based Protection Scheme for Reliable Fault Identification in Series‐Compensated Transmission Lines

IET Smart Grid, Volume 9, Issue 1, January/December 2026.
This paper presents a deep Bidirectional Gated Recurrent Unit (Bi‐GRU)‐based protection scheme for series‐compensated transmission lines using only local voltage and current measurements. The proposed method extracts fundamental‐frequency phasors through discrete Fourier transform and is trained on a comprehensive dataset covering various compensation ...

Optimal Battery Energy Storage Sizing and Dynamic Fault Protection for a Solar–Biomass Hybrid Microgrid in an Islanded Power System

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Optimal sizing and operation of battery energy storage remain critical challenges for islanded microgrids, where supply–demand balancing depends entirely on local resources. This study investigates the techno‐economic optimization and fault‐resilient integration of battery storage within a solar–biomass hybrid microgrid designed for Saint Martin’s ...

Design and real-time implementation of a PMU-based adaptive auto-reclosing scheme for distribution networks

International Journal of Electrical Power & Energy Systems, 2019
Abstract This paper presents an adaptive auto reclosing scheme (AARS), applicable to active distribution systems, which are equipped with Phasor Measurement Units (PMUs). The scheme differentiates between temporary and permanent faults by taking into account the operational conditions of the network when determining the reclosing dead time.

Unlocking the Architecture and Component Distribution of Bioengineered and Derived Colloidal Structures from Blood with Neutron Scattering

Small Structures, Volume 6, Issue 11, November 2025.
Blood‐ and red blood cell (RBC)‐derived colloids are promising biomedical materials but are structurally complex. This work demonstrates how small‐ and ultra‐small‐angle neutron scattering (SANS and USANS) with contrast variation reveal the micro/nanoarchitectures of RBC ghosts, extracellular vesicles (EVs), and plasma proteins.

New Adaptive Reclosing Technique in Unbalanced Distribution System

, 2017
The conventional reclosing of a distribution system is performed after a fixed dead time. However, it may lead to the increased outage time due to delayed reclosing. To solve this problem, this paper proposes a new adaptive reclosing scheme.

Gating residues govern ligand unbinding kinetics from the buried cavity in HIF‐2α PAS‐B

Protein Science, Volume 33, Issue 11, November 2024.
Abstract While transcription factors have been generally perceived as “undruggable,” an exception is the HIF‐2 hypoxia‐inducible transcription factor, which contains an internal cavity that is sufficiently large to accommodate a range of small‐molecules, including the therapeutically used inhibitor belzutifan. Given the relatively long ligand residence
