Research and development of Operation Smart System in CSG

The paper summarizes the development and operation of the technical supporting systems in control centers and substations of China Southern Power Grid (CSG). Smart applications can be, based on functional integration and data sharing, developed for the operation of complicated power grids. A brand new conceptual model of next generation smart system, named Operation Smart System (OS2), is proposed. OS2 consists of the systems in all levels of control centers and substations of CSG, and the systems are linked with open and standardized service buses, called Operation Service Bus (OSB). The definition, principles, technical architecture, modules, and development of OS2 are discussed in detail.
