In the last decade, the concept of grid-forming (GFM) converters has been introduced for
microgrids and islanded power systems. Recently, the concept has been proposed for use in …

This paper presents an overview of the synchronization stability of converter-based
resources under a wide range of grid conditions. The general grid-synchronization …

The grid-forming and grid-following controls are adopted in three-phase voltage source
converters according to different grid conditions. However, the basic operation principle of …

Grid-connected converters exposed to weak grid conditions and severe fault events are at
risk of losing synchronism with the external grid and neighboring converters. This …

In this article, using Lyapunov's stability theorem, the transient stability conditions for a grid-
following voltage-source converter (VSC) are found. These conditions take into account both …

With the increasing integration of power electronics interfaced distributed generators,
transient stability assessment of grid-connected inverters subjected to large grid …

Under fault conditions, virtual synchronous generators (VSGs) are prone to lose transient
stability, similar to synchronous generators. However, the existing studies on VSG transient …

Transient instability events of grid-tied converters probably occur while riding through grid
faults. During low-voltage ride through (LVRT) period, seeing from the converter terminal …

The synchronization instability in the presence of a fault is a main issue for the dynamic
behavior and control of grid-feeding converters. In the literature, the synchronization stability …

Unified virtual oscillator controller (uVOC) inherits the rigorous analytical foundation offered
by oscillator-based grid-forming (GFM) controllers and enables fast overcurrent limiting and …
