An Attack Detection Scheme for Multi-Area Hybrid Power Systems under Covert Attacks

This paper designs an attack detection scheme for multi-area hybrid power systems (MAHPSs) with steamhydropower hybrid configurations under covert attacks. Firstly, the dynamics of the MAHPSs with load disturbances and measurement noises under covert attacks is proposed. Subsequently, an observer is designed to reconstruct the true output of the system under the covert attacks. Then, a coding-based detection scheme is built and it can expose the covert attacker. Finally, the feasibility and effectiveness of the proposed scheme are verified by a simulation example.
