Robust Adaptive Supplementary Control for Damping Weak-Grid SSOs Involving IBRs

Sina Ameli, Lilan Karunaratne, Nilanjan Ray Chaudhuri +1

Subsynchronous oscillations (SSOs) involving grid-following converters (GFLCs) connected to weak grids are a relatively new phenomena observed in modern power systems. SSOs are fur…

Parsimonious System Identification from Fragmented Quantized Measurements

Omar M. Sleem, Constantino M. Lagoa

Quantization is the process of mapping an input signal from an infinite continuous set to a countable set with a finite number of elements. It is a non-linear irreversible process,…
