Comprehensive Study of DC Microgrids Protection: Challenges, Cutting‐Edge Techniques, Machine‐Learning‐Driven Solutions

IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.
ABSTRACT This paper provides a comprehensive examination of the evolving protection challenges within DC microgrids powered by renewable resources and energy storage systems. It begins by delineating the methodological framework of conventional protection, critically assessing schemes based on current, voltage, and impedance to expose their limitations

A Novel Mesh‐Type Medium‐Voltage Distribution Network Topology Enabled by Soft Open Points: Architecture Variants, Capability Analysis, and Operational Strategy

IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.
This paper proposes a novel mesh‐type medium‐voltage distribution network topology enabled by soft open points (SOPs) to achieve system‐wide continuous power flow regulation and overcome the limitations of conventional radial architectures. To ensure efficient integration, a multi‐objective stochastic planning model and a three‐tiered control strategy ...

Decentralised Zone‐Based Protection of Radial Smart Grids Using a Multi‐Agent Scheme

IET Smart Grid, Volume 9, Issue 1, January/December 2026.
A decentralised zone‐based protection is proposed where a multi‐agent scheme is used to manage faults using local agents assigned to each zone of smart grids. ABSTRACT This paper proposes a multi‐agent, zone‐based protection scheme for modern radial smart distribution grids with high penetration of Distributed Energy Resources (DERs).

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 Linear Protection Scheme of Inverter‐Based Distributed Energy Resources: Meeting Fault‐Ride‐Through Requirement

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
This paper presents a new two‐stage protection strategy for active distribution networks that not only addresses selectivity constraints along protected lines but also incorporates fault‐ride‐through (FRT) requirements of inverter‐based distributed energy resources (IBDERs). The proposed coordination strategy (PCS), which distinguishes it from previous
