Enhanced Linear Quadratic Regulator‐Based Strategy for Seamless Transition Between Microgrid Operation Modes

open access: yesIET Power Electronics, Volume 19, Issue 1, January/December 2026.
This paper presents an LQR‐based strategy for seamless transition between grid‐forming and grid‐following inverters in microgrids. The proposed design integrates the comprehensive control loops of the grid‐forming and grid‐following inverters. A systematic, gradient‐based optimization framework is used for selecting the weighting matrices.

Performance Analysis of Distance Relay in the Presence of Grid‐Forming Inverter

open access: yesIET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.
The primary objective of this paper is to investigate the impact of IBRs on transmission line protection in detail. Given that distance protection is extensively used for safeguarding transmission lines and that maloperation of distance relays can have a significant impact on overall system stability, the focus of this work is on distance protection ...

Adaptive DC grid fault reclosing scheme using second-order TET-corrected Reconstructed-traveling-waves

open access: yesInternational Journal of Electrical Power & Energy Systems
Half-bridge modular multilevel converter (HBMMC) based direct current (DC) grids, using overhead lines and DC circuit breakers (CBs), face an urgent demand for selective reclosing methods due to the high DC line fault-probability and the limited ...

Fusion Pores as Regulators of Quantal Size and Cellular Physiology

open access: yesBioEssays, Volume 47, Issue 11, November 2025.
During regulated exocytosis, membrane fusion regulatory factors act directly on SNAREs and membrane lipids to control fusion pore dynamics. This, in turn, leads to a differential amount of cargo release (referred to in this article as “quantal size”) across various cell types, thereby triggering distinct physiological cues.

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

open access: yesSmall 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.

An Enhanced Auto‐Reclosing Scheme for Preserving Transient Stability in AC Microgrids Based on Adaptive Dead Time

open access: yesIET Smart Grid
By focussing on the limitations of fixed dead time (DT) in conventional reclosing methods, this paper highlights its significant adverse impact on transient stability of distributed energy resources (DERs) in microgrid. This vulnerability is particularly

Non-Fault Detection Scheme Before Reclosing Using Parameter Identification for an Active Distribution Network

open access: yesEnergies
The distribution network line has the risk of an unsuccessful three-phase blind reclosing in permanent fault. Based on the response of the inverter of the distributed generation (DG) to the short-term low-frequency voltage disturbance to the line to be ...
