Resynchronization Strategy for a 200kVA Grid- Forming Power Converter
2021 IEEE Energy Conversion Congress and Exposition (ECCE), 2021 During the years, grid connected operation in power systems has been the key factor for renewable energy resource to be able to exchange energy to the electrical grid. However, with the increase of small power systems and micro-grids, the standalone operation and the blackstart of the power system has been increasingly considered a demand in most of ...

Grid-Forming Converters: Control Approaches, Grid-Synchronization, and Future Trends—A Review
IEEE Open Journal of Industry Applications, 2021 In the last decade, the concept of grid-forming (GFM) converters has been introduced for microgrids and islanded power systems. Recently, the concept has been proposed for use in wider interconnected transmission networks, and several control structures ...
