Cyber-attack-tolerant Frequency Control of Power Systems

Cyber attacks are emerging threats in the Internet of Things applications, and power systems typical cyber attack targets. As one most essential operation functions, frequency control is threatened by intrusions, existing centralized mode cannot effectively address risks. In this study, a new distributed cyber-attack-tolerant scheme designed. The also serves as convenient tool for identification. designed controller adopts idea passive fault attenuation, thus simplifying design procedure. With aid graph theory consensus techniques., integral based model predictive (MPC) controllers Compared with type, MPC-based can simultaneously improve dynamic responses tolerance ability under attack. proposed validated via an IEEE benchmark system, effectiveness its application actual verified.
