Hybrid Voltage-Current Control of Grid-Forming and Grid-Following Inverters

CoRR
Grid-connected inverters are required to operate stably under a wide range of grid conditions. However, conventional grid-following (GFL) control may suffer from instability under weak-grid conditions, while grid-forming (GFM) control may exhibit unstable oscillations under strong-grid conditions.
