  1. Adding GE WTG Models to WECC Approved Dynamic Model Library WECC MVWG Meeting June 2014 Eric Bakie

  2. Agenda • Review of GE WTG models in WECC MDF and WECC Cases • Discussion of Adding GE WTG models to WECC Approved Model Library

  3. Background – SRWG Representation Log • Next Focus Area – GE WTG Dynamic Records

  4. Questions Asked • Why are GE WTG Models not on the Approved Model List? • How many GE WTG records are already in the WECC MDF? • How many records represent GE Wind Turbines? • How many records represent non-GE Wind Turbines? • How many records represent solar projects? • Can the GE WTG models be added to the Approved Model List?

  5. Criteria for Adding Models to WECC Approved Model List • Model documented and tested • Model available in all three programs • Justification that the model is needed

  6. GE WTG Model Benchmarking Documentation • Images: GE Energy

  7. GE WTG Model Status • GE WTG Models have been implemented in all three programs • GE PSLF • PSS/E • PowerWorld • GE has indicated that their preference would be to represent GE WTGs with the dynamic models GE developed

  8. Model Records in WECC Cases • A conversion routine to transfer GE WTG models to Phase 2 Generic Models is not available at this time • Inclusion of GE WTG models on the approved model list could reduce the number of models that would need to be converted to Phase 2 Generic Wind Models

  9. More Detailed Review ofWECC MDF GE WTG Records • Review suggests that approximately 50 of 133 records are most likely being used to represent Type 3 and Type 4 WTGs

  10. Discussion Topics • Adding GE WTG models could potentially reduce the need to convert about 50 records • Does this justify adding the GE WTG models? • Could create the possibility of records not getting reviewed and updated • Increases difficulty of tracking Phase 2 implementation • Not adding the models provides opportunity to start fresh by replacing all wind/solar model records with the new Phase 2 Generic Wind/Solar Models • Improves the chance of developing better modeling representation • Easier to track Phase 2 implementation

  11. Modeling of GE Wind Turbine-Generators for Grid Studies Guide • Can a revised GE guide be published that also includes using the Phase 2 Generic Wind Models for modeling GE Wind Turbines with recommended modeling data?

  12. Motion • Add GE WTG models to the WECC Approved model library for use to represent GE Wind Turbines Only • Type 3 (DFAG - GE 1.5MW, 1.6MW, 3.6MW) • Type 4 (Full Converter - GE Multi-Megawatt 2.5 MW)
