Evolution of Power System CIM to Digital Twins - A Comprehensive Review and Analysis

Common Information Model (CIM) is a well established open standard in the power systems domain due to its common shared vocabulary used to communicate messages between various applications. CIM needs to be extended as and when new business requirements arise. CIM has multiple utilisation in power system application ranging from developing an interoperable software application to a cyber-physical system. The latest power system digital twins' trend to establish smarter energy grids highlights new requirements for CIM utilisation. In this context, this paper presented a comprehensive understanding of advancements in CIM research in segments of power generation, transmission, distribution, electricity markets, and consumers. Further, paper discussed the role of digital twins in the emerging power systems.
