    Recent developments in information technology and operational technology allow novel approaches to operate the electric power system. Thereby, the innovative Digital Twin (DT) is one of the most promising concepts as it addresses increasing requirements in terms of dynamic effects, cyber-physical anomaly detection, modelling accuracy and operator awareness. Based on a brief description of the DT concept and its requirements, we present the potential of DTs for automating power system operation. Special focus is given to modelling, simulation, and communication aspects. DT applications covering system operator coordination, anomaly detection and the coordination of DT-based models between the control centre and intelligent substations are presented. The user perspective is evaluated to provide applicable services and functions of DT-based control system modules. The concept is validated by exemplary numerical case studies.

    As real-time applications in information technology (IT) and operational technology (OT) advance, new innovative concepts become possible. IT/OT convergence opens new pathways to design and operate intelligent cyber-physical systems, such as the Digital Twin (DT) concept, which has been discovered as key technology by several industries. This paper describes how centralized and decentralized DTs can help to monitor and control future power systems with special consideration of their interaction in case of corrupted communication from cyber-attacks. While the virtual representation of substations is regarded from the edge computing perspective the control room of the interconnected power system represents the centralized perspective. The concepts allows to have a system wide perspective, while also keeping detailed information at hand. The future system operator in the control room will benefit from services provided by DTs analytical and control features, rising resilience to cyber-physical anomalies and enhance situational awareness.
