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

2. 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

7. 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
