For the problem that smart substation's data cannot be integrated in dispatch center directly, we propose that integrating the data created in smart substation by the ontology technique. In this paper, we design a common method how to establish the local ontology, analysis the data model of primary and secondary equipments of substation according to IEC61850, and then propose a unified XML data format...
During the process of developing Smart Grid, the weak scalability and limited capacity of computing and store in Dispatching System computing center are paid more and more attention. Meanwhile, the advantages of Cloud Computing, such as mass data coumputing and store, huge scalability and good availability, are coming up. So a system structure of Smart Grid Dispatching based on Cloud Computing is...
In order to solve the data permission problem of bidding price from generation side electricity market under the platform of private cloud storage for smart grid dispatching center, a hierarchical role access control policy was proposed based on the subject and object labels. This paper constructed the hierarchical role and attribute forest models through adding the subject and object labels to RBAC...
