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 ...

Isochronous control of a virtual synchronous generator using inertia and excitation emulations with restoration control in a standalone microgrid

IET Smart Grid, 2020
In this study, virtual excitation emulation (VEE) is proposed along with the virtual inertia emulation (VIE) for a virtual synchronous generator (VSG) in a standalone microgrid to improve the AC voltage and frequency profile through the control of power ...

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 ...

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 ...

Fractional‐Order Sequence Impedance Modelling and Stability Assessment of Grid‐Connected Virtual Synchronous Generators

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This study develops a fractional‐order sequence impedance model for grid‐connected virtual synchronous generators, incorporating realistic broadband characteristics of inductive and capacitive components. Utilising harmonic linearisation and the generalised Nyquist criterion, we demonstrate that optimised fractional‐order models significantly enhance ...

A Systematic Review of Grid Following, Grid Forming and Mode Switching Control in MVDC Distribution Networks

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper reviews the common grid‐following (GFL) and grid‐forming (GFM) control principles, technical characteristics, and the limitations of their medium‐voltage direct current (MVDC) applications. In addition, typical switching strategies for GFL and GFM are introduced and analysed. Finally, the applications of MVDC adopting GFL, MVDC adopting GFM,
