Review of Previous Actions
•Develop glossary of terms.
•Perform round robin exercise for Veer term of REWS method using Dataset 3.
•Improve consensus analysis for turbulence renormalisation method makingcalculation steps clearer e.g. flow charts.
•Publically distribute Inner-Outer range concept document.
•Identify and distribute additional validation datasets:
•Galion dataset from SSE
•Dedicate portion of next meeting to Type B effects.
Actions from Dec 2013 Meeting
•Complete Rotor Equivalent Wind Speed (Veer) Exercise (revised deadline 27th ofJune)
•Develop Guideline Document on the Presentation of Power Curve Information
•Develop Guideline Document on the Application of the Turbulence RenormalisationMethod
•Engage with research institutions to test Type B hypotheses using ‘open-source’rotors.
•Develop proof of concept for the ‘Black Box Model’ approach.
•Release python implementation of consensus analysis as open source.
•Investigate the possibility of hosting a PCWG event in the US.
•Publicise meeting via AWEA
•Release 4th RR exercise
1st April 2014
•Improve documentation of consensus analysis of turbulence correction (flow charts)
•Add user interface to Open Source Tool
•Publish Road Map for PCWG 2015 activities.
•Complete 4th Round Robin in advance of December Meeting
•Arrange a Round Robin on Power Deviation Matrix Method
•Arrange a Round Robin on Rotor Equivalent Wind Speed considering inflow.
•Explore enhanced data sharing exercise (possibly utilising open source tool).
•Revisit proposal to use Open Source Rotor to investigate “Type B” performanceeffects.
September 2014
•The members present agreed that the PCWG should continue its activities for 2015. Aroadmap will be prepared detailing the planned objectives and activities for 2015.
•The IEC 61400-12-1 committee and PCWG should aim to hold a further joint meetingin 2015 (timed with an existing 61400-12-1 meeting to minimise travel).
•A manufacturer PCWG member will investigate supplying climate/site specific powercurves for forthcoming the round robin.
•PCWG to add action to 2015 roadmap to develop data specification for climate/sitespecific power curves. This should detail both the input data required by amanufacturer to generate a site specific power curve and the output data required bya developer/consultant in order to do their analysis.
•PCWG to explore establishing a named liaison between the PCWG and the IEC 61400-15 (Resource Assessment) standard committee.
•PCWG to explore preparing a document that would outline the benefits ofmanufacturers supplying power deviation matrices on an informative basis.
•PCWG to conduct round robin on application of power deviation method.
•PCWG members to explore release of additional datasets to the PCWG.
•PCWG to explore adding IEC uncertainty calculation to PCWG open source tool.
