Digitalization of the power supply chain and introduction of smart power grids to integrate renewable energy sources and electric vehicles into the existing power grid have led to a significant increase in the data and information exchange between stakeholders. The paper studies semantic modeling of the power data and its storing in graph databases to enable its fast and reliable retrieval. A common information model enables semantic interoperability of power data related to different processes and time scales, either real or long-term planning. The resource description framework (RDF) is an effective means to serialize data on the Semantic Web. The paper examines the methodology for storing the data serialized as an RDF/XML file in a graph database and approaches for data retrieval data from databases to be used by other business processes. As part of the practical work of this paper, RDF distribution network models will be placed in two graph databases of different concepts (Neo4j and GraphDB) and their performance will be compared and evaluated.
