The Smart Grid Semantic Platform: Synergy between IEC Common Information Model (CIM) and Big Data

Recent innovations in Information Technology, Cloud Computing, Big Data analysis, Internet of Things (IoT) and Artificial Intelligence (AI) are enabling technological solutions that were previously unimaginable, or usually available only for big IT companies, with impacts in both industry and services. The demonstrator named Smart Grid Semantic Platform (SGSP) has been created using these technologies integrating several aspects of the management of an electricity distribution network. The services deployed on the platform concern the visualization of the topographic data and electricity grid assets, as well as the processing and displaying of historical data related to the operation of the networks and/or the result of Big Data analysis. This paper demonstrates how useful the synergy is between the standard semantic model of the electric network (IEC CIM 61968) and the historical data of the time series of medium voltage electricity consumption analyzed using a Big Data platform. Specifically it illustrates the realization of a use case about the calculation of a load index of the electric lines.
