Research of Real-Time Database System for Microgrid

Microgrid is for coordinating the contradictions of large power grids and distributed generation, integrating the advantages of distributed generation, weakenning the impact and negative impacts of distributed generation on the grid and fully exploiting the distributed energy bring value and benefits for the grid and users, proposed a new distributed energy organization and structure. The structural features and operation control method of Microgrid proposed real-time and reliability of the higher demand to real-time database systems of the MEMS. According to CIM guidelines and characteristics of Microgrid, carried out the expansion of Microgrid CIM class, and has been descriptions of Microgrid CIM class. Using the way of object-oriented real-time database stored CIM directly to build systems that follow the standard to avoid model transformation and data mapping, easy to maintain data and improve the efficiency of real-time access to the database.
