Design of Next-Generation Cyber-Physical Energy Management Systems: Monitoring to Mitigation

Abstract

There is a crucial need to enhance the reliability and resilience of our nation’s critical energy infrastructure. Electric power systems are cyber-physical critical infrastructure with distinct, interacting networks comprising electrical, communications, and interdependency layers. Resilience requires modeling and monitoring all layers for prevention, early detection, and proactive threat assessment. This paper presents the research and design of a novel energy management system (EMS) called Cyber-Physical Resilient Energy Systems (CYPRES) to accomplish this goal. The CYPRES EMS architecture and methods are all cyber-physical to cohesively model and analyze the power system as a cyber-physical system (CPS). Results are illustrated for this proof-of-concept solution utilizing a 2000-bus cyber-physical synthetic electric grid.
