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 article 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 article 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.<\/jats:p>","DOI":"10.1145\/3654672","type":"journal-article","created":{"date-parts":[[2024,4,3]],"date-time":"2024-04-03T12:09:16Z","timestamp":1712146156000},"page":"1-22","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Applying Trust for Operational States of ICT-Enabled Power Grid Services"],"prefix":"10.1145","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7037-2246","authenticated-orcid":false,"given":"Michael","family":"Brand","sequence":"first","affiliation":[{"name":"Energy Division, OFFIS - Institute for Information Technology, Oldenburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3593-1780","authenticated-orcid":false,"given":"Anand","family":"Narayan","sequence":"additional","affiliation":[{"name":"Energy Division, OFFIS - Institute for Information Technology, Oldenburg, Germany and Carl von Ossietzky Universit\u00e4t Oldenburg, Oldenburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2340-6807","authenticated-orcid":false,"given":"Sebastian","family":"Lehnhoff","sequence":"additional","affiliation":[{"name":"Energy Division, OFFIS - Institute for Information Technology, Oldenburg, Germany and Carl von Ossietzky Universit\u00e4t Oldenburg, Oldenburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2024,10,22]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1201\/9780203913673"},{"key":"e_1_3_2_3_2","unstructured":"acatech\/Leopoldina\/Akademienunion. 2021.
