4WT4Most recent proposal  & . Not very different from  and only a few changes compared to current WECC model.Used Data graciously provided under NDA from Vestas and Siemens Wind Power, respectively.Acknowledgements:Babak Badrzadeh, VestasNikolaus Moeller Goldenbaum, Siemens
14ABB CASES SHOWN PREVIOUSLY  STILL VALID WITH THIS MODEL Data provide by ABB under NDA to EPRI
15CONCLUSIONWe believe that this model now caters to multiple vendor equipment, and has been shown to give good validation resultsSome minor conventions have to be discussed and finalizedThe “spike” issue need software resolution – several ideas are being pursued
