Abstract

With the continuous development of the power system and the constant expansion of the grid, all kinds of network automation system applications continue to emerge, and how to facilitate the realization within the system or between different applications to share information between systems and application integration has gradually become a hot research. Splicing of the power system network model is the energy management system (EMS) is an important extension application. Power system model stitching, refers to the establishment of inter-regional power system network model different scheduling connections. Network model is defined in a public database, each element of the power system parameters and the connection relationship between the elements, is intended for network analysis applications grid structure and parameters. Power systems are generally not isolated, each power company's internal power system and the adjacent power company systems are interconnected throughout the network model, we need to study a particular area of ??the power system dispatch called internal network , while the external adjacent interconnected system is called an external network, external network boundary device on the internal network through impact. In network analysis, usually by combining multiple sub-regional grid model the formation of large regional networking model, or a particular region of the EMS dispatch functions influenced by the adjacent grids, the need to obtain external network data, such as network configuration and measurement data to improve accuracy, then the model will have stitching problems. Therefore, how to accurately extract the information outside the network model, in what way merge adjacent regional models, etc., have an important significance. Common Information Model (CIM) is the basis of IEC61970 series of standards, is an abstract model, which means that the information is usually included in the EMS model all the major power companies object. It is an electric power system model by defining basic data structure that describes the object classes and attributes, and relationships between them. CIM convenient power system scheduling application software \This article from the CIM model, this paper introduces the IEC61970 protocol overview, detailed study of the power system CIM specification, including the CIM packages, CIM classes and their relationships, CIM modeling methods, analysis of the data carrier network information exchange and combine integrated into an electronic Company CIM / XML project proposed CIM-based power system model stitching implementations. The program model splicing system architecture and the functional modules were designed, the system is divided into model import function modules and model splicing function modules, each module is composed of multiple sub-modules, common implementation model stitching function. Through experimental verification, the system can be done offline grid model stitching application requirements, can be used as an EMS system extensions.
