Study of Bursting Oscillations in VSG System With External Excitation

IEEE Access
When the virtual synchronous generator (VSG) is subjected to an external excitation and the frequency of the external excitation is much smaller than the intrinsic frequency of the VSG system, the VSG system will experience bursting oscillations, leading

Revolutionising Battery Energy Storage Systems Energy Management: Dynamic‐Aware Solutions With Integrated Quantum Particle Swarm Optimisation and Deep Reinforcement Learning

IET Energy Systems Integration, Volume 8, Issue 1, January/December 2026.
ABSTRACT The increasing integration of inverter‐based resources (IBRs) into microgrids (MGs) poses considerable challenges for dynamic stability and energy management, primarily due to their variable and uncertain inertia and damping characteristics.

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 ...

Multi‐Input Backstepping Control for Transient Stability Enhancement in Power Systems With PMSG‐Based Wind Turbines and UPFC

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
In the paper, first, the modelling of a power system with a Permanent Magnet Synchronous Generator (PMSG), Unified Power Flow Controller (UPFC) and Doubly‐Fed Induction Generator (DFIG) is fully considered. Next, the possible candidate control law and its implementation technique on the power network are examined.

Enhanced control and parameter analysis for virtual synchronous generators without PLL

The Journal of Engineering, 2019
Currently, virtual synchronous generator (VSG) technology is proposed to be a solution to stability controlling of micro-source inverter. However, the deviation from phase locked loop (PLL) influences the reference frequency calculating which is ...

VSG Catastrophe Mechanism Based on Bifurcation and Catastrophe Theories

Zhongguo dianli
The virtual synchronous generator (VSG) may have problems that the system bifurcation curve changes and the VSG voltage drops or rises due to catastrophe phenomena during operation, which is not conducive to the stable operation of the VSG.
