Transformation method of heterogeneous common information models

摘要

In order to promote information integration between smart distribution systems, the Common Information Model(CIM) is now widely used as a common semantic basis. With the updating process of CIM, the heterogeneous problem caused by different versions has become a serious impediment to information exchange. Therefore, this paper proposes a transformation method of heterogeneous Common Information Models based on model mapping. First, XML Path Language (XPath) is used to address CIM model mapping pairs, thereby generating an Extensible Stylesheet Language Transformation(XSLT) script for model data transformation. Then, all nodes in the original model are matched and converted corresponding to the new version of the model. In this way, parsing and transformation of heterogeneous models of smart distribution network can be completed. IEEE 13 node feeder model is chosen as an example to verify the accuracy and effectiveness of the proposed method, the conversion result turns out to be precise and valid.
