Bridging ex-ante Simulation and Real-Time AI for System Availability Enhancement

SUMMARY & CONCLUSIONSElectrical distribution systems are becoming increasingly complex in both power capacity and architectural design, driven by sustainability imperatives such as process electrification and the integration of local renewable energy sources. At the same time, sustainability goals demand greater resource efficiency—not only within the site itself but also in relation to external resources, including the electrical grid and expert human input.These evolving requirements necessitate a re-evaluation of traditional RAMS (Reliability, Availability, Maintainability and Safety) methodologies, expanding their scope and incorporating emerging technologies. This shift is facilitated by enhancing simulation tools, which have traditionally relied on idealized mission profiles (the "ex-ante" perspective), and integrating them with real-time data from connected products (the "ex-post" perspective).
