1. IEA Task 32 Power Performance Uncertainty Round Robin
Update for PCWG Glasgow
12 December 2016

2. Overview
Round robin was developed Q1 and Q2 of 2016
Only considers Cat A for power and Cat B wind speed and direction related uncertainty components. Cat B uncertainty for power, density, TI normalization, etc. were not considered.
Round 1 was July through September
Agreed to apply 95% lidar availability filter
Questions about uv,rews,veer,i
Round 2 launched October 27
>40 round robin interested participants, 12 submitted final results
2 incomplete

3. Lidar and power performance in 2016
Power Curve Working Group – various meetings
MEASNET workshop – Sept 26, Hamburg
UniTTe workshop – Nov 18, Copenhagen
IEA Task 32 workshop – Dec 14, Glasgow
Various conference presentations, posters, etc.
Franke and Albers, Power Curve Uncertainty of REWS, WindEurope Summit Sept 27/29 Hamburg

4. Round 2 – Three baseline scenarios
WS1 HH mast and RSD REWS
WS2 HH mast only
WS3 RSD for REWS with short mast

5. Results – Alignment on database

6. Results - Alignment on AEP
WS1 ~ 1.3% higher AEP than WS2
