A Comprehensive Review of Optimal Control Approaches for Inverter Dynamic Voltage Support in Weak and Faulted Grids
The high rate of replacement of synchronous machines by inverter-based resources (IBRs) has increased the role of Dynamic Voltage Support (DVS) during grid disturbances, especially on weak and failed grid conditions. Traditional reactive-current-based grid-support rules can have a poor performance with large R/X ratios...
