“…In this regard, there exists a fundamental difference between the aforementioned availability and timeliness on one hand and data correctness on the other. The first two properties can be measured, e.g., by pinging (or heartbeat) and comparing timestamps, respectively [22]. However, data correctness cannot be directly measured due to the absence of ground truth (i.e., real/actual value).…”

“…As mentioned in Section 1, measuring availability and latency are well-researched topics. Availability of components can be determined by monitoring their heartbeats as shown in [22]. Latency could be measured using network monitoring tools such as CheckMK [5].…”

“…This is trivial and the unavailability of a suitable server results in the failed state. Typical CPESs have redundant servers, where a backup server takes over in the case of primary server failure [22]. If at least one server is available, the solvability is checked based on the measurements available within the specified time interval.…”

“…It can be seen in Figure 5 that the state estimation service can fail either due to a server failure or loss of field measurements. In the case of the former, suitable actions include fixing the server with active backup [30] or redeployment and reallocation of the state estimation algorithm using virtualization [22] can be performed. In the latter's case, actions such as repairing sensors and rerouting network traffic can be performed.…”

Digitalization enables the automation required to operate modern cyber-physical energy systems (CPESs), leading to a shift from hierarchical to organic systems. However, digitalization increases the number of factors affecting the state of a CPES (e.g., software bugs and cyber threats). In addition to established factors like functional correctness, others like security become relevant but are yet to be integrated into an operational viewpoint, i.e. a holistic perspective on the system state. Trust in organic computing is an approach to gain a holistic view of the state of systems. It consists of several facets (e.g., functional correctness, security, and reliability), which can be used to assess the state of CPES. Therefore, a trust assessment on all levels can contribute to a coherent state assessment. This paper focuses on the trust in ICT-enabled grid services in a CPES. These are essential for operating the CPES, and their performance relies on various data aspects like availability, timeliness, and correctness. This paper proposes to assess the trust in involved components and data to estimate data correctness, which is crucial for grid services. The assessment is presented considering two exemplary grid services, namely state estimation and coordinated voltage control. Furthermore, the interpretation of different trust facets is also discussed.CCS Concepts: • Hardware → Smart grid; • Security and privacy → Trust frameworks.

The intermittent energy supply from distributed resources and the coupling of different energy and application sectors play an important role for future energy systems. Novel operational concepts require the use of widespread and reliable Information and Communication Technology (ICT). This paper presents the approach of a research project that focuses on the development of an innovative operational concept for a Smart Integrated Energy System (SIES), which consists of a physical architecture, ICT and energy management strategies. The cellular approach provides the architecture of the physical system in combination with Transactive Control (TC) as the system’s energy management framework. Independent dynamic models for each component, the physical and digital system, operational management and market are suggested and combined in a newly introduced co-simulation platform to create a holistic model of the integrated energy system. To verify the effectiveness of the operational concept, energy system scenarios are derived and evaluation criteria are suggested which can be employed to evaluate the future system operations.
