An Incremental System-of-Systems Integration Modelling of Cyber-Physical Electric Power Systems

Simulation of Cyber-Physical Systems (CPS) can be quite complex due to heterogeneity of their components and their interactions, which include physical phenomena, levels of abstraction used in modelling the physical and computational structures and processes, and engineering approaches to CPS design and analysis. The concept of system-of-systems (SoS) to designate complex integrated CPS infrastructure engineered as the interacting network of physical and computational processes in electrical networks is proposed. Due to the heterogeneity, the SoS simulations are architected as distributed co-simulation of multiple models. One of the standardized distributed co-simulation platforms is the High Level Architecture (HLA) that runs as a Federation of interacting simulators where the term Federate (FED) is used for designating each system that is a component of an SoS. The lack of a methodology for model characterization and integration into an accurate co-simulation framework of such a complex SoS limits the capability to analyse and design critical CPS infrastructures in electric power systems.
