Abstract

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 significantly increases the vulnerabilities, which further underscores the importance of cyber security. As a result, cyber-physical system security of the power grid is a critical area encompassing vulnerability assessment, anomaly detection, and mitigation for substations and the Supervisory Control and Data Acquisition systems. The purpose of this presentation is to provide new concepts and testbed-based methodologies for the integrated cyber-power systems. Future research directions will be discussed.
