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 …

Six-Switch Step-Up Common-Grounded Five-Level Inverter With Switched-Capacitor Cell for Transformerless Grid-Tied PV Applications

Authors: Reza Barzegarkhoo, Yam. P. Siwakoti, Naser Vosoughi, and Frede Blaabjerg
Abstract:
Photovoltaic (PV) string inverters with transformerless grid-connected architecture are the most commonly used solar converters owing to their appliance-friendly and cost-effective benefits. A novel circuit configuration for these converters is presented in this study, which …
