Distributed Hierarchical Control for Fast Frequency Restoration in VSG-Controlled Islanded Microgrids
Authors: Kuo Feng, Chunhua Liu
Abstract:
As microgrids develop rapidly, more inverters are adopted to achieve DC/AC or AC/DC/AC conversion of distributed generators (DGs). Replacing the large rotary generators with inverter-based sources results in a lack of inertia in the grid. The virtual synchronous generator (VSG) control …
