PGDTF,

 

The materials for Pass 2 of the GIC Model Build have been posted to MIS. For this pass the expectation is that the transformer table will be fully updated along with any other corrections and updates that need to be made to the substation and bus table. The goal at the end of Pass 2 is to be able to find preliminary GIC flows. The GIC Modeling Expectations has details on how to use the template if those are needed.

 

In the MIS postings under: GIC Case Build Pass Files, there is a zip file with all the necessary materials. Inside the zip file is also a folder called Data Issues. Please review the sheets in there and make corrections based off of them if the buses and stations are yours. These contain details on the stations without buses, stations with buses whose stations don’t exist, and duplicate stations. These will all need to be corrected by the end of Pass 2. A new full database validation has also been included along with the line data issues spreadsheet that was released in the previous passes (which has not been updated).

 

Pass 2 End Date: 4/26/2019

 

Pass 2:

·         For Pass 2, the only submissions ERCOT should receive are modified GIC templates that are updating the transformer table and making corrections to the bus and substation tables

·         The transformer I, J, and K bus order in the template already matches the RAW file so do not change the bus order.

 

As a result of Pass 1, a set of solving GIC AC models updated with new 6.9(2) units and submitted Idevs and an updated template have being released.

 

Please don’t hesitate reach out and call or email me if you have any questions on what should be updated, how to use the template, or you have any issues or questions.

 

Here is the overall schedule as a reminder.

 

 

Thanks,

 

Eric
