Inertia Response Improvement in AC Microgrids:A Fuzzy-Based Virtual Synchronous Generator Control [PDF]

, 2020
The absence of rotational masses from synchronous generators in converter-interfaced microgrids leads to a lack of inertia. Consequently, the system exhibits steeper frequency variations and higher frequency nadir, which may degrade the dynamic ...

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 ...

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 ...

Virtual synchronous generator: Modifications, stability assessment and future applications

Energy Reports, 2022
The distributed generation (DG) integration into the power system is growing rapidly. Therefore, the power system experiencing low inertia and damping because DG possesses no or low inertia causes severe stability issues.

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,

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 ...
