Research on Control of Information Flow in Smart Distribution Grid

Analyses the demand to information flow control technology in smart distribution grid, points out that IEC 61968 based information exchange bus has defects in information flow control, and proposes a framework that consists of flow direction control, information content control and flow runtime control. Based on principle of active and collaborative control, this paper proposes also detailed designs of flow direction arrangement, adapter identification, flow direction analysis, syntax validation, semantic validation and runtime control which consist of start-stop control, traffic control and priority control. The framework and its control functions provide a flexible, uniform and stable solution to information flow control in smart distribution grid.
