Summary:
The Common Information Model (CIM) is one of the most recommended standards for future smart grids. Especially its data model provides almost all semantic information which is needed to model smart grid specific issues. Required but still missing information can be added by following given methodologies. To make the CIM applicable it is necessary to serialize it using communication standards with respect to the corresponding use cases. As standardization is a means to cope with interoperability challenges in smart grids, standards should be used whenever economically feasible and possible. Within this contribution, the focus is on two automation standards which are recommended for smart grid applications. On the one hand, the IEC 61850 is used for substation automation and on the other hand, the OPC Unified Architecture (IEC 62541) for more general industrial automation. Combining those two communication standards with the CIM leads to important benefits in cases of integration of components, systems and devices. Both combinations follow different approaches and were developed independently from each other. The first discussed approach deals with the harmonization of CIM and IEC 61850 on instance level and the second approach introduces CIM semantic based information modeling within an OPC UA server-client architecture.
