A System of Systems (SoS) is a large complex system, with varying degrees of operational independence, managerial independence, evolutionary development, geographical distribution and lifecycle independence. Critical Infrastructure such as the electrical grid contains all the aspects of a SoS. Due to the ever‐increasing complexity of the grid, a single model encompassing all aspects of the grid would be impossible. Hence, we need to abstract the problem into a SoS set of aspects and examine the system both at the SoS level, as well as the detailed level. This will require the use of standardized systems modeling tools such as the Systems Modeling Language (SysML), and the Unified Architecture Framework (UAF) to define the overall goals, strategies, capabilities, interactions, standards, operational and system architecture, system patterns and so forth. This paper will examine the electrical grid as a SoS, define common characteristics, identify issues and vulnerabilities and MBSE strategies for addressing them.
