“…For instance, the authors in Reference
26 proposed a state and attack observer for LFC system to realize decentralized attack detection and mitigation, noting that the load variation was assumed to be known, which makes it less applicable. In Reference
10, an
dynamic reduced‐order observer‐based decentralized detection scheme was adopted to reduce the conservativeness of the residual threshold and improve the detectability to FDIAs. To detect more complex cyber‐attacks, two distributed attack detection methods were investigated in References
27 and
28, respectively, in which the detector contained a decentralized unknown input observer (UIO) and a distributed Luenberger‐like observer.…”
