A Review of Transient Support and Security‐Stability Enhancement Control Strategies for Grid‐Forming Voltage Source Converter‐Based High Voltage Direct Current Transmission

open access: yesHigh Voltage, EarlyView.
ABSTRACT Amid the ongoing global energy transition, the short‐circuit ratios of AC power grids are continuously decreasing. Grid‐forming voltage source converter‐based high voltage direct current transmission (GFM VSC‐HVDC) systems have therefore come to the forefront of attention.

Research on overvoltage and fault of a UHV AC/DC hybrid system

open access: yesThe Journal of Engineering, 2019
In view of the overvoltage problem of an ultra-high-voltage DC (UHVDC) AC/DC hybrid system, this study analyses the overvoltage condition under various fault types and gives the identification criterion of the overvoltage form. Firstly, the model of the

Co‐Optimisation of Battery Energy Storage Systems for Voltage Regulation and Reverse Power Flow Control in PV‐Enriched Low Voltage Distribution Network

open access: yesIET Smart Energy Systems, EarlyView.
A hybrid GA–PSO framework determines the optimal placement and sizing of distributed battery energy storage systems in a PV‐enriched low voltage feeder, whereas dynamic consensus control (DCC) coordinates their operation. The integrated approach mitigates voltage rise and reverse power flow and promotes balanced utilisation of multiple storage units ...

AGIcam: An open‐source Internet of Things–based camera system for automated in‐field phenotyping and yield prediction

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Continuous, high‐frequency monitoring is essential to capture rapid phenological transitions and dynamic crop responses to the environment. However, most phenotyping platforms lack the temporal resolution and automation required for consistent, season‐long trait assessment.

Design and Implementation of a Digitalised Marine Aids to Navigation Monitoring System for High‐Density Maritime Traffic Waters: A Case Study of the Strait of Malacca

open access: yesApplied Research, Volume 5, Issue 5, October 2026.
A digitalised Aids‐to‐Navigation monitoring system (ARMS) was deployed across 478 installations in the Strait of Malacca and Malaysian waters, integrating multi‐sensor edge validation, hybrid AIS/VHF/cellular communication, and a centralised platform. It achieved 98.3% availability and cut fault‐detection time from weeks to just 8.4 min.

Novel method for restraining 35 kV shunt reactor switching overvoltage – phase controlled breaker

open access: yesThe Journal of Engineering, 2019
Phenomena such as current chopping, arc reignition and equivalent current chopping might appear when cutting off shunt reactor. Overvoltage caused by switching will lead to interphase fault in related equipment and inter-turn insulation damage in the ...

Dynamic Reconstruction of Metal–Organic Framework and Metal–Organic Framework‐Derived Electrocatalysts for Bifunctional Oxygen Electrocatalysis in Alkaline Energy Devices

open access: yesElectrochemical Science Advances, Volume 6, Issue 5, October 2026.
ABSTRACT Alkaline oxygen reduction reaction (ORR)/OER bifunctionality is central to rechargeable Zn–air batteries, reversible fuel cells and regenerative electrolysis. These technologies are promising for mitigating carbon emissions resulting from fossil fuel energy dependency, driving the energy sector towards a carbon‐neutral energy cycle.
