Three‐Dimensional Adjustable Operating Domain of VSG Parameters Considering Inertia, Damping and Short‐Circuit Ratio

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
The three‐dimensional adjustable operating domains of VSG parameters are obtained under the two model constraints. These domains consider inertia, damping and SCR. ABSTRACT Virtual synchronous generators (VSGs) can provide flexible inertia and damping support, but these two parameters are strongly coupled. Inappropriate parameter tuning may deteriorate

Enhanced Phase‐to‐Phase Distance Protection for AC Lines With Power‐Electronics‐Interfaced Sources

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper proposes an adaptive enhanced phase‐comparison distance protection (PCDP) strategy to address the maloperation risks caused by high penetration of power electronics‐interfaced sources (PEIS). Unlike the conventional scheme with a fixed operating boundary, the proposed strategy dynamically adjusts the protection zone, effectively capturing ...

A Novel Coordinated Control Strategy Between the Grid‐forming SVG Equipped With Supercapacitors and Renewable Energy Gathering Stations to Support Frequency Stability

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
Grid‐forming static var generators (SVG) with supercapacitors and power electronics can provide dynamic reactive compensation and inertia support, but challenges exist in coordinating their inertia support with automatic generation control (AGC) units in renewable energy gathering stations.

A Novel Coordinated Control Strategy for VSG to Enhance Power Tracking Speed Without Degrading Inertia Support Capability

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
ABSTRACT The virtual synchronous generator (VSG), as a representative grid‐forming control method, has become a key technology in distributed renewable energy systems. However, there exists an inherent trade‐off between fast power reference tracking and high virtual inertia support in conventional VSG control.

Adaptive Virtual Inductor‐Based Current‐Limiting Control Strategy and Transient Stability Design for Grid‐Forming Converters Under Symmetrical Grid Faults

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
An adaptive virtual inductor (AVI)‐based current‐limiting control strategy is proposed for grid‐forming converters under severe symmetrical grid faults. It dynamically adjusts the virtual inductor through an output current amplitude control loop to limit fault current and enhance reactive current injection while maintaining voltage source ...
