Study on IEC 61970/61968 based information integration for smart distribution grid

The full information integration and highly unified information model is one of important embodiments of the smart grid connotation and features. According to the requirements and problems of information exchange between correlated systems in smart distribution grid, an information exchange platform for smart distribution grid based on standardized information model of IEC61968/61970, coarse-grained information exchange model of IEC61968, publish/subscribe mechanism and SOA is proposed. The architecture, function requirement and key technologies of this platform are studied. The platform provides a unified information exchange bus supported by standardized information model as well as flexible and efficient message transmission mechanism, achieves realtime, quasi-real-time and non-real-time information exchange between various distribution systems, and supports the business flow and application integration of multiple systems. Based on the information exchange bus, the platform achieve information sharing by the loose coupling means and ensure the flexibility, efficiency, security, maintainability and scalability of information exchange for smart distribution grid.
