In view of the deficiency of the future model and historical model management in the smart grid dispatching and control system

this paper proposes a multi-version construction and management technology of power grid model based on application and time dimension. The method takes the use of lightweight file database and CIM/E files as the persistent storage medium of the multi-version model to implement security isolation among multiple versions. The different operational models are classified by logical model sets

and then the technical scheme of constructing and managing multi-temporal model versions among different transactions are realized. Furthermore

this paper proposes specific solutions for some key technologies

such as model comparison and consolidation between different versions

the model validation of future version and online process management. This technology has become a pilot application in the dispatching and control center for its ability to meet the demands of multiple business applications towards a multi-temporal version model

enhancing the supporting ability of the system control to construct the future model

backtrack historical model

model sharing and whatnot. This work is supported by State Grid Corporation of China.
