The architecture of the smart grid dispatching and control system is based on horizontal integration and vertical interaction. It is required to be of security

large capacity and high efficiency. Thus a new database management technology needs to be researched with database management as the core. The characteristics of the real-time database

commercial relation database

timeseries memory database

and timeseries disk database are described first along with the system’s requirements on data management

followed by the data management architecture

the key technology of data management

and the interface and maintenance of data accessing. The data management technology has successfully been applied to different levels of the dispatching and control systems with the database as the core

providing powerful support to secure

stable and efficient operation of the system.
