A New MIMO ORC Architecture for Power Oscillation Damping Using Remote Feedback Signals under Intermittent Observations

A new multi-input multi-output (MIMO) observer-driven reduced copy (ORC), i.e., MIMO-ORC architecture is proposed for wide-area damping control using multiple doubly fed induction generator (DFIG)-based wind farms to mitigate the issue of intermittent observations with multiple feedback signals and actuators. In this context, the concepts of cyber-physical self-coupling and cross-coupling are introduced, and their impact on the deterioration of closed-loop performance with data-dropout is quantified using an analytical derivation. A framework for the stability analysis of MIMO-ORC architecture is also proposed. Finally, time-domain simulations show the superiority of the proposed approach over its single-input single-output ORC counterpart in a 16-machine New England-New York power system.
