Review of Proposed Round Robin 5: “Power Deviation Matrices” Afternoon Wrap Up: 16.45 – 17.00 Venue for next meeting Public distribution of presentations and minutes Review of Previous Actions Actions from Dec 2013 Meeting • Develop glossary of terms. • Perform round robin exercise for Veer term of REWS method using Dataset 3. • Improve consensus analysis for turbulence renormalisation method making calculation 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. 1st April 2014 • Complete Rotor Equivalent Wind Speed (Veer) Exercise (revised deadline 27th of June) • Develop Guideline Document on the Presentation of Power Curve Information • Develop Guideline Document on the Application of the Turbulence Renormalisation Method • 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 September 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” performance effects. October Meeting Key Outcomes • The members present agreed that the PCWG should continue its activities for 2015. A roadmap 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 meeting in 2015 (timed with an existing 61400-12-1 meeting to minimise travel). • A manufacturer PCWG member will investigate supplying climate/site specific power curves for forthcoming the round robin. • PCWG to add action to 2015 roadmap to develop data specification for climate/site specific power curves. This should detail both the input data required by a manufacturer to generate a site specific power curve and the output data required by a developer/consultant in order to do their analysis. • PCWG to explore establishing a named liaison between the PCWG and the IEC 6140015 (Resource Assessment) standard committee. • PCWG to explore preparing a document that would outline the benefits of manufacturers 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.
