Modular system architecture for processing of CIM

Abstract

Due to the increased share of distributed generation (DG), there are less conventional power plants available that offer ancillary services, for example reactive power provision, for the electric grid. Photovoltaic systems or wind turbines can also provide reactive power, but in contrast to conventional power plants present state-of-the-art is that availability weather dependent. Intelligent software and algorithms, like optimization tools, may then be used to coordinate DG for the provision of ancillary services. Such software requires that information about the electrical grid will be provided automatically and in a standardized way. Common Information Model (CIM) is a standard for exchanging information about the power system and defined in IEC 61970. This paper describes the handling and modular processing of CIM, in order to provide software for distributed management systems (DMS). In addition, a test environment for such software is presented
