CIM standard for dynamic model exchange

EPRI sponsored a project to extend the CIM standard to support the exchange of dynamic power system models needed to perform system simulation studies for system dynamic assessment and for planning purposes. Current dynamic model exchanges require customized import/export software to convert from one proprietary format to another for each pair of vendor products, thus inhibiting free exchange between different simulation/analysis software tools. The business case and extensions to the CIM UML model and the new reference manuals for both standard and user-defined dynamic models are described. Results of recent interoperability tests to validate the completeness and correctness of the proposed standard are presented. IEC TC57 WG13 is currently progressing the drafts as new international standards that will be available in 2010 for use in improving overall transmission grid reliability and security. This work directly supports the NIST Smart Grid interoperability objectives.
