Reliability Modeling Considerations for Emerging Cyber-Physical Power Systems Prepared by Task Force on Reliability Consideration for Emerging Cyber-Physical Energy Systems under IEEE PES Reliability, Risk and Probability Applications Subcommittee

TLDR: The objective of this paper is to define the three-layer model and report a generalized framework for combined reliability modeling and evaluation for power system planning and operations.

Abstract: Power system operation considering an increasingly complex cyber infrastructure may be one of the key factors of the next generation power systems. The effective operation of a power system in a massively deployed cyber network environment will be affected by cyber network reliability. Therefore, it is vital not only to understand the operation of a cyber network and its reliability, but also it is critical to integrate the interdependency of cyber and power systems into power system planning and operations. This requires a three-layer approach to reliability modeling and evaluation. The cyber and power layers are interconnected by the information layer. The objective of this paper is to define the three-layer model and report a generalized framework for combined reliability modeling.
