Interoperability test and plugfest provide a congenial environment to test and assure interoperability of power grid devices helping to achieve equipment plug and play. However, interoperability analysis and evaluation are very time-consuming and error-prone tasks to process a huge amount of network communication packet data collected in the test. Therefore, the big challenge we are faced is how to efficiently analyze interoperability. To address the challenge, the National Institute of Standards and Technology (NIST) has developed an interoperability analysis tool for the International Electrotechnical Commission (IEC) 61850-9-2 standard-based merging units (MUs). This paper introduces a software tool that can read and parse IEC 61850-9-2 packet data from a packet data markup language (PDML) file and then automatically analyze the interoperability of IEC 61850-9-2 sampled value (SV) messages published from MUs based on the of IEC 61850-9-2:2011 protocol. The interoperability analysis includes data analysis of the media access control (MAC) layer, link layer, and application layer of IEC 61850-9-2 SV messages. This tool has successfully been used to analyze nineteen sets of IEC 61850-9-2 SV messages collected from some commercial physical and simulated MUs provided by seven vendors in the Utilities Communications Architecture International User Group (UCAIug) IEC 61850 Interoperability (IOP) Testing and Plugfest event held in October 2017.
