TSS ACTIVITIES (unchanged)
• CIP-014-01, MOD-032-1, TPL-001-04, TPL-007
• Response to 08 Sept 2011 AZ to CA Outage
– Relays, DPM Changes, WECC RAS/Ctg Definition
• BCCS
– Base Cases created by BCCS in 2015.
– Training provided in 2013 and available in 2014
• Certification/de-certification Process of Study
Software
– Following MSRATF software requirement
development…will assign to JUG
October 2014

TSS: Path Ratings/Projects
Coordination
• Mostly quiet except for SONGS removal (13 Oct)
October 2014
4
TSS: Response to AZ to CA Outage
• Sharing of Contingencies and RAS files
– Began in 2013, TSS to ask for this again this fall
• WECC RAS/Contingency Format/File
– Software vendor to assist WECC in creating these
for 2015 base cases (start in 2015)
• Sole sourcing this…workshops starting in 2015
– Outcome will be a WECC wide RAS/Ctg file that
functioned for each WECC published base case.
• Distributed with each case
October 2014
5
TSS: Joint Users Group
• Assumes all MSRATF duties fall of 2014
– Disestablishing MSRATF Jan 2015
– JUG is the open and transparent forum for
directing software changes and allocating WECC
funds for study software development
• New or changing standards require JUG be
PROACTIVE
– Work within TSS framework to meet requirements
of standards
October 2014

TSS:CIP-014 Guidance
• Fast moving physical security standard
– Metcalf attack precipitated this
• Guidance developed by TSS work group
– Spells out studies needed to get off list
– Requires detailed work to PROVE that loss of
station is tolerable
• Partnership with Peak Reliability
– They have controlling editorial rights

TSS: CIP-014 Example Exposure
• Columbia Grid footprint

TSS: GMD Data and Study
October 2014

SRWG ACTIVITIES
•
2014 Base Cases
–
Attempted to develop jointly with BCCS and
without
•
•
BCCS work in progress (2015 success date?)
Data Preparation Manual
–
Approval for 2 flavors (present/BCCS)
•
MOD-032-01 (Short circuit discussion)
•
Location Data (for GMD Studies)
October 2014

SRWG Logs
• Rep Log
– Shows steady improvement until we reset it with
new data checks
• This is an on going trend
• Recall that “Performance Log” has gone away
– Morphed into a listing of study results listed in
Annual Study Program report.

SRWG: Short Circuit Data
• MOD-032 asks for short circuit data
– TSS Chair letter to be sent out requesting this data
for 2015 data year
– Asking simply for what you presently have
October 2014

MOD-032-01:
R1. Each Planning Coordinator and each of its Transmission Planners shall jointly develop
steady-state, dynamics, and short circuit modeling data requirements and reporting
procedures for the Planning Coordinator’s planning area that include:
1.1. The data listed in Attachment 1.
1.2. Specifications of the following items consistent with procedures for building the
Interconnection-wide case(s):
1.2.1. Data format;
1.2.2. Level of detail to which equipment shall be modeled;
1.2.3. Case types or scenarios to be modeled; and
1.2.4. A schedule for submission of data at least once every 13 calendar
months.
1.3. Specifications for distribution or posting of the data requirements and reporting
procedures so that they are available to those entities responsible for providing
the data.
MOD-032-01:
R4. Each Planning Coordinator shall make available models for its planning area reflecting
data provided to it under Requirement R2 to the Electric Reliability Organization (ERO)
or its designee to support creation of the Interconnection-wide case(s) that includes
the Planning Coordinator’s planning area

SRWG: Nuances of MOD-032-01
• Nuances
– “…steady-state, dynamics, and short circuit
modeling data requirements...”
– “…for building the Interconnection-wide case(s)…”
– “Data must be shareable on an interconnectionwide basis to support use in the Interconnectionwide cases.”
• Practically speaking this suggests WECC map
short circuit data to power flow cases to some
extent.
