Resilient Two Degree-of-Freedom IMC for Time Delay Attack Mitigation of Interconnected Power System
Bibliographic record
Abstract
Cross-boundary power systems are more susceptible to cyberattacks, especially time-delay attacks (TDAs), which can disrupt system functioning by delaying communications. This paper offers a resilient two-degree-of-freedom internal model control (2DOF-IMC) strategy to reduce the negative impact of TDA on power system stability. This controller provides an exceptional level of disturbance rejection and reference tracking under attack conditions. To design the proposed controller, the higher-order plant dynamics are reduced by Hankel-based model order reduction approach. The effectiveness of the proposed 2DOF-IMC method is demonstrated via simulation experiments on an interconnected power system for different TDA scenarios. Comparison with conventional IMC (C-IMC) reveals advanced strength and improved frequency control mechanism. The developed framework reduces time delay destabilizing influences, guaranteeing proper functioning of the system during hostile cyber-attack events. The evidence supports the use of resilient control technologies for defending modern power grids from these TDAs. This research provides a significant step toward enhancing the security and stability of interconnected power systems in the face of evolving cyberattack landscapes.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
