To achieve the objectives of the Smart Grid efficiently, it is necessary to integrate all the components of the power system from generation to the end user. They should relate to each other in a transparent manner, i.e. independent of their technologies and protocols. This concept applied to Smart Grid networks ensures efficient communication whether the information systems are used on different types of infrastructure or even at a distance. For this, the use of the concept of ontology from computer science helps greatly. Ontology is the philosophical study of the nature of the basic categories and their relationships. Ontology-based strategies applied to interoperability constitute a framework for organizing information and are used in the representation of components of power systems.
