REMC Task Force 004 "Model Validation"

Short name	REMC TF 004
Scope	Establish the general aim of model validation and how it is used in type and project certification Establish a generic framework for model validation – including a sufficiently detailed mathematical treatment. Such a generic framework must allow further details (for instance in an Annex), for dealing with the details for the validation of each model type individually (such as power performance, loads, siting models, noise, grid, etc) On top of the generic model, the details for power performance validation shall be worked out in detail, also with regards to the mathematical framework An example of the level of detail that at least needs to be worked out is as follows: Assuming that the mathematics involved will include hypothesis testing, then the most common tests used in this context use the variance included within the data as input to the hypothesis test. Specifically for power performance (and most likely also loads) the majority of the uncertainty comes from Category B uncertainty, which often does not fully translate into variance in the data. Hence we would have to agree specifically on the hypothesis testing to make sure that the uncertainty on the input is properly reflected in the outcome of the hypothesis test The task force is also asked to define the split in work between RECBs and RETLs regarding model validation and develop the documents needed to establish competence areas for RECBs and RETLs according to this split Finally, the establishment of a model validation methodology, mathematical framework and RECB/RETL competence areas should not change the fact that the measured power curve is still required as input to the type certification. The intent isto define in more detail how this input is used
