5. SRWG Chairman’s Report (Mclean)
Ms. Mclean provided a summary of the SRWG Chair’s Report to the TSS. The 2015 Base-Case
Compilation Schedule was presented and accepted without any changes. The PCC has directed
modification of the DPM to include modeling of primary relays only. The TSS has also directed that
additional DPM modifications are to be made such as including GIC data reporting requirements
and sequence data reporting requirements. It was also commented that the PCC has passed a
motion not to include sequence data reporting requirements in the DPM.
ACTION ITEM: SRWG to determine the next case to be used for a BCCS case review.
ACTION ITEM: SRWG to begin modification of DPM, etc. to implement generator labels.
6. WECC Technical Staff Report (Doug Tucker)
Late Data Log
Jon Jensen presented the 2014 Ten-Year Data Bank Late Data Log as of July 2014. No late data
submittals for initial data submittal for the bulk of the cases with the exception of WAPA who was 1
week late for the 2017 LSP-1 case. Late data for the submittal of comments was the same with
most cases being on-time with the exception of WAPA who was one week late on the 2019-20 HW1
cases.
Status of the Data Bank
Three cases have been approved since last meeting: (1) 2014-15 HW3-OP, (2) 2014-15 LW2-OP, (3)
2015 HSP1-OP. Data is currently being complied for three cases: (1) 2019-20 HW1, (2) 2020HS2, (3)
2017 LSP1-S. Next case is the 2024 HS TEPPC.
Comments to approved cases
7. Compliance Subgroup (Jonathan Young)
The BCCS DPM
Jonathan Young made a motion that SRWG approve the BCCS version of the DPM to take effect
when the BCCS is fully implemented, at a future date to be determined, with the understanding
that future changes to the active DPM will be implemented into both versions. Motion passed
to approve the BCCS Data Submitter’s Guide.
Data Submitter’s Guide
Jonathan Young made a motion that SRWG approve the BCCS Data Submitter’s Guide. The
motion was seconded and passed.

Annual Study Program Log
Eleanor Ewry made a motion to accept the presented list of standard outages and direct WECC
staff to use them on prepared cases beginning with the next case to be compiled. The motion
was seconded and passed.
Light Load
Eleanor Ewry made a motion that SRWG request of WECC, or if not available of the BA for
historical hourly load data by BA, for load duration curve by BA and all four seasons for the
2013 year. The motion passed.
BCCS implementation
Made a motion to use the 2015 LS1-OP with an October 10, 2014 request date and the
2020HS2 with a December 1, 2014 request date. The motion was seconded and passed.
9. Review MDF Process (Jon Jensen)
Review MDF Process
Gary Keenan: annual process for UFLS includes dynamic relay data for UFLS. The PRC-006 data
submittals are due to the UFLS Review Group July 1 each year. Looking at performance in the
assessment, Gary observed incorrect load shedding; further review indicated that the MDF did not
reflect WECC posting for the case dynamics data. Same token: had member BAs submitting data:
Bonneville had sent in data to WECC Staff with remove-and-replace instructions for getting the
data into the WECC MDF. The end result was that the submitted data was included in the pre-run
dynamics data file, but never made it into the MDF file or operating case posting. Gary commented
that this is a compliance element and the need to demonstrate compliance using the downloaded
cases and downloaded MDF. This instance has identified a potential gap data reporting submission
procedure for inclusion in the MDF.

Eric presented the transition plan for removing the Phase 1 wind and solar models from the WECC
MDF and replacing the models with the REMTF Phase 2 models. The presented plan includes
MVWG member comments.
MDF review
Eric performed a detailed review of the MDF by manually inspecting the data and developing
model counts for existing wind and solar records.
Implementation plan
The developed implementation plan calls for review and replacement of all existing records with
the Phase 2 REMTF models with a grace period for the Phase 1 models. There was interact of the
REMTF task force with vendors, thus the Phase 2 models should be the last changes to wind/solar
models for some time.
Tracking spreadsheet for model implementation/retirement
Eric also developed and presented a new spreadsheet that contains the dynamic model
implementation schedule for the new Phase 2 wind/solar models and also the new overcurrent
relay models. The sheet was amended during SRWG group discussion.
Eric Bakie made a motion that the spreadsheet as shown and amended be accepted by the SRWG
as the model implementation schedule and posted on the SRWG webpage. The motion was
seconded and passed.
Secondary Protection (Pamela Mclean)
Pamela indicated that PCC has directed that only primary relays be modeled.
11. Dynamics Corrections (John Gross)
Dynamic Corrections
Demonstrably “wrong” data notably the wt1p model, is in the MDF but have not had any progress
in changing it from the responsible party. MVWG has asked REMTF to take action to make a
recommendation to either have WECC staff remove the non-useful models such as wpt1 or replace
them with more accurate data such as wt1p_b.
Eric Bakie commented that if a transmission planner is not getting good models then the TP should
be empowered to submit good data especially if bad data is know to impact the study results.

Eric also shared with the group that EPRI is developing a m atlab package that uses disturbance
data (i.e. PMU recordings) to validate wind/solar plant models; the tool will be available through
EPRI website.
12. Zero-Sequence Data For MOD (John Gross)
PC roles
MOD-032 requires that Planning Coordinators to collect data and make it available to the ERO
or it designee upon request. Planning personnel need to have control of the information that
goes into the base cases in order to meet the case objectives. MOD 026 and MOD 027 mandate
that equipment owners validate their modeling data. MOD-032 R1 Procedures must be
JOINTLY developed with transmission planners.
Short Circuit Data
John Gross moved that WECC staff create a location for storing Short Circuit Data. The motion
was seconded and passed.
DPM Additions
GIC data
John Gross made a motion to add language as proposed for GIC data for substations. The
motion did not pass.
13. Distance Relay Model (Andrew Christenson)
MVWG agreed to have models coded, developed and made available for those who want to use
them. MVWG voted against mandating and requiring collection of the data and including distance
relay modeling comprehensively in the MDF. Struggling to maintain quality of data in the MDF and
MVWG felt that generic distance relay settings would provide adequate coverage without creating
the problem of having to collect and validate installation-specific distance relaying data.
