Tracy Rolstad TSS Chair TSS Chair Report March 2014 Salt Lake City, UT 1

Overview Approval Items – Data Preparation Manual – 2013 Annual Study Report – MSRATF White Paper – Assistance on Lat/Long for GIC TSS Activities – Includes MSRATF activities MVWG Activities SRWG Activities March 20142

TSS ACTIVITIES Composite load Model Phase 1 in play in 2014 Response to 08 Sept 2011 AZ to CA Outage – Relays, DPM Changes, WECC RAS/Ctg Definition BCCS – Hope to have Base Cases created by BCCS in Syntax description and documentation of Project File NEEDED ASAP – Training provided in 2013 and available in 2014 Certification/de-certification Process of Study Software – Following MSRATF software requirement development March 20143

Response to AZ to CA Outage Sharing of Contingencies and RAS files – Began in 2013 WECC RAS/Contingency Format now exists – In one software…assistance needed in incentivizing fast development in other software WECC v.s. Peak – Unclear on when data sharing pipeline will be established between WECC and Peak Some data is at Peak and not WECC Have perceived data security issues at WECC been addressed? – For RAS and Contingency files March 20144

AZ->CA Response: Ctg and RAS WECC defined and approved a Ctg & RAS syntax – Issued a contract to a software supplier Specs again are in the public domain – Software supplier delivered software for acceptance testing on 22 October out of 3 software programs has it coded presently How can we get others to develop software? March 20145

MVWG ACTIVITIES – Updated Phase 2 Wind Type 3 Model Specifications Document – Phase 2 Wind Summary Specifications Document – Updates to the Approved Dynamics Model List – [MSRATF] Distance Relay Model Specifications – [MSRATF] Directional Overcurrent Relay Model Specifications (for the addition of the directional and load encroachment elements to overcurrent relays) March 20146

SRWG ACTIVITIES 2014 Base Cases – Developed jointly with BCCS and without Changes to Annual Study Program – Focus on quality base cases – Performance Log retirement Data Preparation Manual Revision BCCS Syntax !!! March 20147

SRWG: Data Preparation Manual – Proposed amendments The data preparation Manual will be amended to include the following additions under the dynamic data Requirements section of the DPM: Line and Transformer Protection Include line and transformer overcurrent protection models where approved models are available on BES transformers and transmission lines that have overload trip settings below 150% of their seasonal normal rating, or below 115% of the highest emergency rating SPS Protection Include SPS protection models where approved models are available including safety Nets, Wide Area Protection Systems (WAPS), Local Area Protection Systems (LAPS) and Remedial Action Schemes. March 20148

TSS Report Summary 2014: – BCCS – Composite Load Model, phase 1 – Relays (Overcurrent and distance) – Ctg & RAS Definition Need to respond to Unified TPL Standard General Trend – Agility in responding faster to external forces FERC/NERC, etc Physical Security and GIC Data and Study Needs – Fast moving Physical Security standard… March 20149
