Study on Data Management of Fundamental Model in Control Center for Smart Grid Operation

The control center in smart grids requires the collaboration among different specialized groups to ensure the safety, reliability, greenness and efficiency of power system. However, each specialized group is interested in different aspects of the network model. In order to improve the teamwork and timeliness, the fundamental models should be managed in a unified way. This paper summarizes the requirements for data management of fundamental models, presents a concept of three-mode models, and designs the architecture of generic model access services. With the generic model access services, the differences of real-world model databases will be shielded, and the future virtual model can be managed as versions. The upper applications can obtain the fundamental model information through the data broker component and business model data through the business data organizing component.
