2

Proposed WECC REMTFRenewable 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

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

8

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

9

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

SRWG Discussion

• Is the proposed implementation plan reasonable?

• SRWG Member Recommendations

16

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
