Cyber-Physical System Security of the Power Grid (Erőművek és az átviteli hálózat kiberfizikai védelme)

The electric power grid is a complex cyber-physical system that forms the lifeline of a modern society. Its reliable and secure operation is of paramount importance to national security and economic well-being. The power grid today is a highly automated network, wherein a variety of communication networks and information systems are interconnected to the physical grid for the purpose of monitoring, protection, control, and market functions. The increased reliance on information and communications technology in the smart gird will significantly increase the vulnerabilities, which further underscores the importance of cyber security. As a result, cyber security of the power grid encompassing vulnerability assessment, anomaly detection, and mitigation of the substations and Supervisory Control and Data Acquisition systems are among the important priorities. The purpose of this presentation is to provide new concepts and testbed-based methodologies for the integrated cyber-power systems.
