This paper proposes an intrusion-detector-dependent secondary frequency control approach to enhance the attack-resilient capability of microgrid control systems. While most of the existing attack-resilient controllers assume the perfect accuracy of intrusion detection systems, we consider the possible false detection of intrusion detectors against denial-of-service attack. The proposed frequency controller adjusts its control gains based on the detected attack choice rather than the actual attack choice, as the actual attack choice can only be detected, instead of assuming surely known to a defender. Test results verify that the designed controller can sustain the stability of the microgrid under a high false detection rate.

Abstract

This paper proposes an intrusion-detector-dependent secondary frequency control approach to enhance the attack-resilient capability of microgrid control systems. While most of the existing attack-resilient controllers assume the perfect accuracy of intrusion detection systems, we consider the possible false detection of intrusion detectors against denial-of-service attack. The proposed frequency controller adjusts its control gains based on the detected attack choice rather than the actual attack choice, as the actual attack choice can only be detected, instead of assuming surely known to a defender. Test results verify that the designed controller can sustain the stability of the microgrid under a high false detection rate.
