Study of Monitoring False Data Injection Attacks Based on Machine-learning in Electric Systems

False data injected by hackers can interfere with power system state estimation and pose a great threat to the safe and reliable operation of modern power systems (FDIA). The traditional bad data detection method can not effectively detect such attacks. In this paper, by extracting relevant power system measurement characteristic value and use the historical data as the sample, using three classical machine learning algorithms (Perceptron, KNN, SVM) of false data injection attack detection, and respectively in IEEE-9, IEEE-57, IEEE-118 simulation platform for test, verify the supervised machine learning algorithm is applied to the validity of false data injection attack detection.
