Grid-Forming Control

These examples demonstrate grid-forming control for grid-connected converters. The example 12.5-kVA converter, RFPSC uses a power-synchronization loop for synchronizing with the grid [1]. In 12.5-kVA converter, disturbance observer, disturbance-observer-based control is used [2].
