Research on heterogeneous data integration for Smart Grid

Compared with the traditional power grid, Smart Grid can improve the reliability and availability of the entire grid, while it continues to reduce the costs and improve the efficiency. It is getting more and more attentions, the characteristics of integration and interaction require the exchanging and sharing of the information, as well as the seamless connection of various parts. The Ontology as a shared conceptual model and formal specification provides a good way to resolve the semantic heterogeneity problem. By the research of past means of heterogeneous data integration, combined with the current status of the grid, a model of heterogeneous data integration is proposed to adapt the future Smart Grid. Based on XML and Ontology, combined with Cloud services, This model provides a good method to solve the heterogeneous problem from the syntax and sematics. Finally, SCADA(Supervisory Control and Data Acquisition) data is used to validate the model.
