Multi‐point‐line Grounding Fault Section Identification in Urban Distribution Networks by Using Coordinated Multi‐Source Data

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
A multi‐source data collaborative fault section identification method for high fault‐tolerant distribution networks is proposed. The method constructs a robust mixed‐integer linear programming cooperative model by integrating zero‐sequence current direction features and fault indicator alarm signals.

Recovery Control Strategies and Overcurrent Suppression for Bipolar Hybrid Cascaded MTDC Systems Under DC Faults

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
The paper explains the issue of managing and recovering DC faults in bipolar hybrid cascaded MTDC systems, the combination of LCCs to achieve power density and MMCs to provide flexible control in long‐distance power transmission, and the integration of large‐scale renewable energy sources. The paper examines fault behaviours in the LCC section, LCC‐MMC

Advanced Hosting Capacity Assessment in Distribution Systems Using a Centralised HIL‐Based Setup

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
The paper proposes a two‐stage framework for assessing distributed energy resource (DER) hosting capacity that combines an initial optimisation‐based estimate with real‐time validation using a centralised IEC 61850–compliant Hardware‐in‐the‐Loop (HIL) platform and a digital twin of the IEEE 33‐bus system.

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.

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

IET 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

Adaptive DC-Line Reclosing Strategy for VSC-HVDC Transmission from Desert–Gobi–Wasteland Renewable Energy Bases

Energies
Reliable fault-nature identification before DC-line reclosing is essential for overhead VSC-HVDC transmission from desert–Gobi–wasteland renewable energy bases because reclosing into a permanent fault may impose severe secondary stresses on converters ...
