Model-Predictive Dual-Control Loop With Improved Current-Limiting Capability for Grid-Forming Inverter Under Grid Faults

IEEE transactions on power electronics
Current-limiting capability is crucial for fault ride-through of grid-forming (GFM) inverters. Most current-limiting schemes for GFM inverters are implemented within classical linear controllers, which cannot guarantee optimal performance in case of ...

Grid-Forming Inverter-Based Resource Research Landscape: Understanding the Key Assets for Renewable-Rich Power Systems

IEEE Power and Energy Magazine
The shift to net zero energy systems has changed the face of our power grid. Traditional large-scale synchronous generators found inside coal and natural gas plants are being replaced with inverter-based resource (IBR) technologies. This transition to an
