SCR760  Recommended Changes Needed for Information Model Manager and Topology Processor for Planning Models

Approved Urgent sponsor Wesley Woitt on behalf of the SSWG posted 2010-11-04 ercot.com
ReasonERCOT decided that system modeling information feeding downstream applications, market apps, operations systems, and planning models would reside in one database, which is the Information Model Manager. The Topology Processor is a piece of software that takes the Information Model Manager database (a breaker/switch model) and modifies the data into a planning model (a bus/branch model). This model will then be input into the Model On Demand (MOD) software which will be used to create future planning cases. Since 2009, the SSWG began a detailed review of the Topology Processor output and has noted a number of deficiencies in the Information Model Manager and/or Topology Processor. These deficiencies have to be corrected to produce usable cases for planning analyses; therefore, rather than make these corrections on the back end of the process through MOD each time a case is created, we strongly urge the adoption of the changes suggested in this SCR. The deficiencies with the current output of the Topology Processor are listed in a ranked order of importance to the SSWG. Potential resolutions have been offered; however, further discussion with ERCOT and its vendors will be needed before finalizing.
