Conceptual Design and the Future Development for Operation Smart System in China Southern Power Grid

The paper summarizes the current status of the technical supporting systems in the control centers and substations of China Southern Power Grid (CSG). Smart grid 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 system, named Operation Smart System (OS2), is proposed. OS2 provides an integrated framework that integrates all functionalities of the current systems in control centers and substations. These functionalities act as modules and are linked with an open and standardized service bus, called Operational Service Bus (OSB). The definition, principles, technical architecture, modules, and key technologies of OS2 are discussed in detail. A case study on a prototype system of power system operation cockpit (POC) demonstrates the feasibility of the system framework and the key technologies. It is believed that the research and development of OS2 will significantly benefit the grid operation of CSG.
