Meeting Report

Presented “Transmission Model Exchange” powerpoint summarizing the CIM model authority based exchange processes.

The presentation will be posted on the CIM User Group website.

Discussion included relevance to ERCOT, WECC and Eastern Interconnect situations.

Demaree discussed recent presentation to the NERC DEWG (Data Exchange Working Group).

We need to establish an ongoing relationship between DEWG and the Model Exchange WG.

DEWG has an interest in seeing that the Interop tests become more realistic: Real models.

More complete coverage of possible modeling patterns.

Testing that relates to real usage.

DEWG is interested in model change notification system.

Relationship between state estimation quality and model quality was discussed. State estimation residuals provide important feedback about modeling accuracy.

Action: Britton/Ortleib will follow up with DEWG to continue liaison.
