Resilient Monitoring and Control Digital twins with a real-time connection to telecontrol technology, combined with automation and virtualization, enable faster anticipation and better utilization of flexibilities. Together with real-time trust assessment, this can achieve more resilient operation of complex cyber-physical energy systems. This is the focus of research by the "Resilient Monitoring and Control" group at OFFIS.
In the energy sector, a profound paradigm shift has begun, primarily driven by the extensive integration of distributed energy resources, the liberalization of energy markets, and the changing roles of actors, such as consumers to prosumers. To continue monitoring and controlling energy systems, they are increasingly permeated by information and communication technologies (ICT) and automation technologies. However, these technologies also increase the system's complexity and makes it more vulnerable to cyberattacks.
The resilient operation of such a transforming, decentralized, and dynamic energy system heavily depends on accurately and in real-time representing the system to anticipate events as early as possible and exploit available flexibilities. Such a digital representation, also known as a digital twin, is based on data collected using information and communication technologies (ICT).
A key challenge is to derive a meaningful understanding of the collected data, such as in the form of models or event identification, so that it can be used for anticipating and ensuring the resilient operation of the system. Following this vision, the key topics of the "Resilient Monitoring and Control" (ROC) group are:
- Digital Twins: How can digital twins be integrated into the operational routine of an energy system to ensure resource-efficient and resilient energy supply in the future?
- Trust: How can the trustworthiness of components, data, and services in cyber-physical systems be assessed to enable better event prediction and decision-making?
- NextGen Grid Control: How can grid control systems be designed to address the challenges of cyber-physical energy systems and develop new functionalities that are purposefully integrated into HMIs?

The research in these key topics aims at a new, innovative system architecture to monitor and control complex cyber-physical systems in a resilient manner. Established standards from the domain, such as the common information model (CIM), are combined with established standards from other domains, such as MQTT, and new concepts, such as trust assessment and hierarchically nested digital twins, into a modular, highly flexible, and resilient system.
Research Topics
Digital Twins
A digital twin is a dynamic virtual copy of a real existing system. They are versatile and enable more effective development, analysis, or management of the represented system, depending on the application. Originally stemming from product lifecycle management, digital twins are also unlocking various new applications in the energy sector. Learn more…
Trust
Trust is a subjective, context-dependent, and multivariate sense about an entity with respect to various aspects. It enables more comprehensive monitoring of components, data, and services. This provides new opportunities for capturing complex events and, consequently, for decision-making. Learn more…
