DESIGN OF AUTOMATED SMART GRID CIM INTEROPERABILITY TEST SYSTEM BASED ON TTCN

We design a TTCN-3 based smart grid CIM test system for verification and validation of CIM interoperability among test nodes complying with IEC 61968 standards. The designed system allows a tester to easily generate TTCN scripts by graphically creating message sequence charts for validation of test verdicts. It also contains a test script execution engine for test automation with the TTCN scripts. The execution engine provides a function of matching CIM messages sent from test nodes at a run time with message templets generated by a tester for validating of test verdicts. These features of the designed system enable automating smart grid CIM interoperability tests between test nodes.
