Cyber-Attack and Reliability Monitoring of The Synchrophasor Smart Grid Network

The recent advancement of synchrophasor measurements technology in the conventional power grid can monitor and control state variables network very accurately at a high sampling rate real-time. complete observability system states be achieved through Phasor Measurement Unit (PMU). inclusion zero injection bus (ZIB) optimized total number PMU requirements for observation network. communication channels between measurement devices centers are highly vulnerable to cyber threats. Thus, an anomaly that occurs with during cyber-attack affect system’s reliability. Therefore, monitoring reliability has become essential healthy operation. Synchrophasor enhance wide-area surveillance security functionality. However, dependability such technologies context information accessibility yet investigated coherent model. Growing electric defence levels mitigate impact cyber-attacks is essential. cumulative effect discussed this paper by optimizing PMUs deployed interruption load while taking ZIB into account.The backup deployment modeling also presented secure PMU. indices, Interrupted Load Probability Index (ILPI) Expected Demand Not Supplied (EDNS), used evaluate networks integrating probability unavailability due intrusion.
