Dynamic Complex-Frequency Control of Grid-Forming Converters

IECON 2024 - 50th Annual Conference of the IEEE Industrial Electronics Society
Complex droop control, alternatively known as dispatchable virtual oscillator control (dVOC), stands out for its unique capabilities in synchronization and voltage stabilization among existing control strategies for grid-forming converters. Complex droop control leverages the novel concept of ``complex frequency'', thereby establishing a coupled ...
