Synchronization of Inverters in Grid Forming Mode

IEEE Access, 2022
This article compares two strategies for seamless (re)connection of grid-forming inverters to a microgrid powered by droop-controlled inverters. While an incoming inverter must be synced to the microgrid, seamless syncing and power-sharing are technical ...
