AISOP aims to create an AI-assisted decision support system for the electric distribution system operators (DSOs) to drive decarbonisation that is underpinned by advanced digital technology. The decision-support system securely and privately acquires, processes, interprets, and exploits data for the benefit of DSO operational planning. In this context, AISOP expands data-driven techniques for improved operational planning in distribution/local grids with high shares of DERs by integrating AI/ML-based solutions, enhanced situational awareness and market incentives. Within the proposed project we combine (i) data access and ingestion (ii) distribution grid situational awareness, (iii) decision-support for distribution grid management (iv) dynamic tariffs, (v) digital platform integration with exploitation through test and training environments. The developed solutions will be disseminated within EXPERA and validated using the three demo-sites and living labs in Switzerland and Germany.
