Microgrid synchronization and grid connection
This paper first addresses the challenges of networking microgrids with grid-forming inverter in droop control. Then, it proposes a pre-synchronization algorithm to improves the synchronization speed and transient stability. Microgrids, characterised by low inertia, power electronic interfaces, and unbalanced loads, require advanced strategies for voltage and frequency control, particularly. . Pre-synchronization control is needed when the microgrid changes from an off-grid state to a grid-connected state.
