Data-Driven Extension of “Measurement-Based Fast Coordinated Voltage Control for Transmission Grids”

In Tang et al. (2021) a measurement-based coordinated voltage controller for transmission systems was developed. As essential model information, the controller incorporates linear sensitivities between device set-points and voltages/power injections in the grid. This letter details how online sensitivity estimation using robust least squares can be used in place of model-based sensitivities, leading to a model-free voltage control approach.
