1 John Gross SRWG Chair SRWG Chair Report March 2015 WECC HQ

2 2 Where are we headed? Data Preparation Manual status MOD-032 implementation plan and associated DPM 2015 Base Case Compilation Schedule status Base Case Coordination System Model Implementation Schedule Renewable generation dispatch Balancing Authority Area representation WECC contingency analysis RAS Workshop and File Format specifications MOD-033 coordination with MVWG Topics

3 3 What is the point of SRWG’s efforts? o Provide data to support study requirements Changes on their way (or already here) o Node-breaker representation o RAS and contingency modeling o Relay emulation How should we react? o Develop staged implementation plans o Get ahead instead of behind Where are we headed?

4 4 TSS approved 4 digit zone numbers o Also included technical writer edits Data Preparation Manual Rev 4 4 Digit Zone addition Rev BCCS-4 4 Digit Zone addition Rev BCCS-5 MOD-032 Implementation Non-BCCS BCCS DPM Revisions

5 5 TSS approved SRWG’s implementation plan and associated DPM Focus will begin shifting to Planning Coordinators How to collect data from non-registered entities? MOD-032-1 Implementation

6 6 TSS approved revisions to 2015 schedule o Load description o Shifting summer operating cases Separate approved item to replace TEPPC case with 10 year light load case o Requested by WestConnect, NTTG, ColumbiaGrid, and California ISO 2015 Base Case Compilation Schedule

7 7 Patch provided following December meeting did not resolve all critical issues Siemens has hired a consultant to support troubleshooting issues Further update? Base Case Coordination System

8 8 New approved models o ccomp – cross current compensation Need to add to implementation schedule? Model Implementation Schedule

9 9 TSS is requesting renewable generation to be dispatched to non-zero o Not realistic for all renewables to be off o When end-users turn them on, models cause problems Represent realistic output for scenario Renewable Generation Dispatch

10 10 TSS and MVWG support including BA representation in base cases o Similarities to Westwide System Model o More closely mimics actual system controls o Comparison to L&R submittals Implementation pending software development and utilizing the new versions o Or changing existing Areas in cases to BA’s, no software changes required Balancing Authority Area Representation

11 11 Create new Area Move buses to new Area by filter Select an Area slack bus Change control to Area Slack Set interchange for new Area to ACE Error o Attempt to match existing solution o Unspecified interchanges absorbed at slack BA Representation Demo

12 12 WECC Staff is continuing to run contingency analysis on operating base cases SRWG will support data collection efforts as needed WECC Contingency Analysis

13 13 April 2, 9-11 MDT (Webinar) o Intro to RAS modeling and RAS/contingency file format o Types of RAS that can be modeled May 27-29 (Salt Lake) o In person workshop o Create models of your specific RAS for use o PE continuing education credits available RAS and Contingency Modeling

14 14 SRWG was directed to work with MVWG to develop an implementation plan o Compare planning power flow model to state estimator o Compare planning dynamic model to actual system response Merging WSM and planning model? MOD-033-1 Implementation Plan
