What is a grid forming converter?
A grid-forming converter (GFC) is a crucial component in modern power systems, particularly those aiming for high levels of renewable energy integration. GFCs are designed to provide essential grid services like voltage and frequency support, inertia emulation, and power regulation. These converters can operate autonomously in islanded mode and as part of the grid, offering stability during transitions. Challenges faced by GFCs include current control limitations and potential instability in stiff grids. To address these issues, innovative control strategies involving additional current loops and adaptive model predictive control methods have been proposed. Improvements in voltage control loops, especially in fast power loops, are essential for enhancing the performance and stability of GFCs in both grid-tied and stand-alone operations.
