Enhanced control and parameter analysis for virtual synchronous generators without PLL

open access: yesThe 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 ...

Adaptive Virtual Inductor‐Based Current‐Limiting Control Strategy and Transient Stability Design for Grid‐Forming Converters Under Symmetrical Grid Faults

open access: yesIET 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 ...

Reliability Improvement of GFM Inverters: Diagnosing DC‐Side Instability Mechanisms and Overvoltage Faults Induced by PV and ESS

open access: yesIET Power Electronics, Volume 19, Issue 1, January/December 2026.
This paper investigates GFM inverter reliability by analysing DC‐side dynamics from PV and ESS, which can cause DC‐link overvoltage and instability. We demonstrate that high PV generation is a key threat, while counter‐intuitively, limiting ESS capacity can enhance stability by damping control‐induced oscillations.

Small‐Signal Weak‐Grid Instability of Grid‐Forming Converters Considering DC‐Capacitor Voltage Dynamics

open access: yesIET Power Electronics, Volume 19, Issue 1, January/December 2026.
In conclusion, based on the typical GFM grid‐connected systems that either ignore or incorporate the DC‐capacitor voltage dynamics, their weak‐grid small‐signal stability problems are systematically studied in the time domain and their critical conditions are explicitly obtained in the first time.

Inrush Current Suppression and Coordinated Control Strategy for Grid Black Start Using a Grid‐Forming Wind‐Storage System

open access: yesIET Power Electronics, Volume 19, Issue 1, January/December 2026.
To address the inrush current and switching impact from transformer no‐load closing during grid black start with grid‐forming wind turbines, this paper proposes a Virtual flux envelope smoothing (VFES) strategy and a multi‐mode coordinated black start control method for grid‐forming wind‐storage systems based on actual engineering parameters.
