Application of an Ontology-Based and Rule-Based Model in Electric Power Utilities

The evolution of power distribution systems has considerably increased due to the technologies present in the grid. All these technologies lead to augment the complexity of the information exchanged between heterogeneous applications. One way to address this problem is to use ontologies for the identification and association of semantically corresponding information concepts. We show through the use of the IEC/CIM (International Electro technical Commission/Common Information Model) ontology, how it is possible to take advantage of a formal representation and semantic enhancement to support complex tasks. We present a formal approach to process semantic data for electric power utilities. We show that modern semantic technology gives us the possibility to process complex tasks within a reasonable time for a large-scale problem of real power networks.
