A Weak-Grid Supportive Scheme via Community-Scale BESS Controlled as a Virtual Synchronous Generator (VSG)

Electronics
Weak-grid operation, with a low short-circuit ratio (SCR), degrades voltage and frequency regulation and impacts the power control performance of inverter-based resources, triggering oscillations. This paper proposes a community-scale battery energy storage system (BESS)-supported grid-forming control scheme, where the grid-forming inverter acts a ...

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 ...
