Abstract：After frequency disturbances occur in the external power grid，grid-forming converters（GFCs）areprone to synchronization instability. Analysis shows that adding a low-pass filter（LPF）to the active loop can causeconflicts between the transient stability and frequency stability of GFC，while adding LPF to the re...

Abstract：Due to the large rotational inertia of synchronous machines，frequency changes caused by faults areminimal. In contrast，new energy systems have smaller rotational inertia，which can result in more significantfrequency variations during faults. These larger frequency fluctuations inevitably lead to changes in ...
