Mechanism and Control Analysis of Synchronous Frequency Resonance in Distributed Power Generation System Connected to Grid

Energy Science &Engineering, Volume 14, Issue 4, Page 2263-2276, April 2026.
Small‐signal modeling reveals that insufficient system damping positions conjugate poles near the imaginary axis, fundamentally explaining the SFR mechanism. A virtual resistance control is consequently proposed to damp the resonance and effectively suppress SFR, which is validated through Hardware‐in‐the‐Loop experiments.

Stability analysis of parallel virtual synchronous generators and suppression of low‐frequency oscillations

Energy Conversion and Economics, Volume 7, Issue 2, Page 149-161, April 2026.
Abstract With the increasing penetration of power electronic devices in power systems, virtual synchronous generator (VSG) technology has garnered widespread attention for its ability to provide inertia and damping support to the grid. However, while simulating the external characteristics of synchronous generators, this technology also introduces ...

Characteristics and operational control strategies of grid‐forming long‐/short‐duration energy storage systems: A review

Energy Conversion and Economics, Volume 7, Issue 2, Page 127-148, April 2026.
Abstract Energy storage systems (ESSs) are increasingly critical for maintaining the stability and flexibility in power systems with rising renewable penetration. Grid‐forming (GFM) ESSs have emerged as a pivotal technology, capable of providing essential voltage and frequency support by establishing grid references in converter‐dominated systems. This

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 ...

Modeling and Control of a Multi‐Energy Microgrid With Wind LVRT and Battery Pre‐Synchronization Strategy

Energy Science &Engineering, Volume 14, Issue 1, Page 266-280, January 2026.
This study establishes a hybrid microgrid model integrating a Doubly Fed Induction Generator (DFIG), a photovoltaic (PV) array, and a battery energy storage system, and proposes a coordinated control framework. The DFIG regulates DC‐bus voltage through the grid‐side converter and performs maximum power tracking via the rotor‐side converter, while the ...

Low‐Frequency Oscillation Suppression Strategy Based on NPOD‐SVC‐VSG Grid‐Connected System

IET Energy Systems Integration, Volume 8, Issue 1, January/December 2026.
ABSTRACT The power control loop in a virtual synchronous generator (VSG) exhibits inherently insufficient damping, making it prone to low‐frequency oscillation (LFO) under disturbances. Moreover, the dynamic coupling between active and reactive power can induce unnecessary reactive power fluctuations during active power transfer.

Synergistic Phase‐Damping Strategy for Transient Control of dVOC‐Based Inverter in Microgrid System

IET Energy Systems Integration, Volume 8, Issue 1, January/December 2026.
ABSTRACT Transient stability in Dispatchable Virtual Oscillator Control (dVOC) during interconnection operations in microgrid systems remains a significant challenge. This paper proposes a Synergistic Phase‐Damping Strategy (SPDS) that integrates phase compensation and virtual damping within the dVOC control framework to improve transient stability ...
