CIM-based Database Research On Graphic Model And Database Integrative System

Distributed Generation is a certain solution to solve the energy problems in the future. Integrating DG and load to be a controllable regional micro-grid, this systematic view greatly advances the development of DG. The research of energy management optimization method in DG system is beneficial to improving economy and efficiency of the system as well as reducing the discharge of CO2, which is also good for supplying custom-build energy service.To facilitate the integration of EMS applications developed by different vendors,the integration of all applications among entire EMS systems developed independently,or the integration between an EMS system and other systems concerned with different aspects of power system operations.EPRI CCAPI project came to reduce the cost and time needed to add new applications to an EMS,and to protect the investment in existing applications that have being worked effectively in EMS.Graph-model-base integration means integrating graph and relative information in the database. The graph and data are helpful only on the condition that they are connected according to some relation. Then the attribution of data can be defined and modified by operating relative graph, in a word, the graph and the data are bonded together. It can supplement and derive the content of database automatically, bond the graph and data, when the graph manipulation is done, which is very convenient. So graph-database integration is mainstream technology in present graphic system.Excellent database system is the precondition to keep the energy management of DG stable. On the basis of studying conventional energy management system, the main content of this paper is as follows:1) the establishment of a database system based on CIM2) the preparation of a database management system3) study of the mapping between The CIM model and relational database4) study of the CIM / XML language and the transformation of relational database, and adopting the tidal current computation to validate its correctness.
