Synchronization Stability of a Grid Forming Converter Under the Effect of Current Limit in Voltage Dips with VI Based Current Limiting Method: Analysis and Solution

This article deals with the synchronization stability in voltage dips of a Grid Forming Converter (GFC) operating with Virtual Impedance based current limiter. In the event of a grid fault, if the converter can't evacuate the active power while limiting the current, stability issues arise. In t...

Summary:This article deals with the synchronization stability in voltage dips of a Grid Forming Converter (GFC) operating with Virtual Impedance based current limiter. In the event of a grid fault, if the converter can't evacuate the active power while limiting the current, stability issues arise. In this paper this effect is analyzed, and a solution is proposed.
