Transition Plan for Removing Wind Phase 1 Generic Models WECC SRWG Meeting July 2014 Eric Bakie

Proposed WECC REMTF Renewable Energy Model Implementation Plan  Key stakeholder input (REMTF, IEEE, IEC) Model specifications approved by MVWG and TSS Prototype model implementation tested Model validation against plant-level field data (difficult and ongoing) Models implemented in release version of commercial software programs Model user guidelines Webinar on WECC/REMTF model development, deployment process Update Approved Dynamic Models List WECC workshop on RE modeling Model validation guidelines and tools (in process) WECC request for data submittal using new models, with grace period

Agenda Review Wind and Solar Records in Current WECC MDF Review MDF Parsing Spreadsheet Tool MDF Review Results Review Proposed Implementation Timeline for Phase 2 REMTF Wind and Solar Models Group Discussion

motor1 Model Conversion Progress (12 mo.) Model Conversion of Type 1 Wind using motor1 from SRWG RepLog Case Rep Log Number of unapproved models (motor1, in WECC Basecase data 14hps1a July 2013 36 14hs4a Nov 2013 31 14ls1a March 2014 15hsp1a July 2014 Conversion to Phase 2 estimate is 526 records

MDF Review Observations Large blocks of units represented using synchronous generator models (i.e. genrou(tpj), exst1, ggov1, etc.) Dynamics Data records do not match Powerflow Turbine Type Turbine Type 21 – Type 1 Wind Turbine MDF Comment = Type 4 Plant Model Records = Type 3 Models Large blocks represented without dynamic control models gewtg or genrou – model only Large blocks represented without full collector system equivalent

Implementation Plan Goal Update existing WECC wind/solar dynamic records with REMTF Phase 2 Wind and Solar Models Typos in Table 1 / 1A: wt1p(2p) => wt1p_b VRGTPA => VTGTPAT FRQTPA => FRQTPAT

Notes on wt1p and wt2p REMTF recommended removing wt1p and wt2p models from the WECC Approved Model List No pitch controller for passive stall turbines wt1p_b should be used for active stall turbines REMTF will take action to inspect MDF Make recommendation of either deleting wt1p and wt2p records or replacing records with wt1p_b models

2014 SRWG Base Case Compilation Schedule Data Request to Start Transition

2015 SRWG Base Case Compilation Schedule Phase 2 Target Completion Date Remove Phase 1 Models Add un-converted models to PPMDTF list PPMDTF review target completion date

Proposed Implementation Timeline MVWG Renewables Workshop 6/17/2014 Initial WECC Data Request 7/18/2014 Target Completion Date 6/05/2015 Remove Ph. 1 Models from Approved List 6/05/2015 Begin PPMDTF Review 7/10/2015 Target Completion of PPMDTF Review 12/18/2015

Relevant Timeline for NERC Modeling Data Verification Standards R1, R3, R4, R5, R6 07/1/2014 R2 (30%) 07/1/2018 R2 (50%) 07/1/2020 R2 (100%) 07/1/2024 MOD-027-1 R1, R3, R4, R5 07/1/2014

Relevant Timeline for NERC Modeling Data Reporting Standards

SRWG Discussion Is the proposed implementation plan reasonable? SRWG Member Recommendations

Next Steps Add SRWG Member Comments Publish Phase 2 Implementation Plan Post to SRWG Site Develop Tool for Tracking Progress Stand Alone or Replog Encourage data submitters to improve steady-state and dynamic data representation of wind and solar plants in WECC Basecases Encourage use of WECC Wind and Solar Modeling Guidelines Develop Tool for checking Powerflow Turbine Type Data against dynamics data modeling records
