The wide area m onitoring of power systems is implemented at a central control center to coordinate the actions of local controllers. Phasor measurement units (PMUs) are used for the collection of data in real time for the smart grid energy systems. Intrusion detection and cyber security of network are important requirements for maintaining the integrity of wide area monitoring systems. The intrusion detection methods analyze the measurement data to detect any possible cyber attacks on the operation of smart grid systems. In this paper, the model-based and signal-based intrusion detection methods are investigated to detect the presence of malicious data. The chi-square test and discrete wavelet transform (DWT) have been used for anomaly-based detection. An IEEE 14-bus system is simulated using real time digital simulator (RTDS) hardware platform for implementing attack and detection schemes.
