Terms of reference
REMC Joint Working Forum "IECRE/TC88 Joint Working Forum on Model Validation"
  • Ensure collaboration between experts from IECRE and TC88 on the topic of Model Validation in general. This will cover topics such as power performance, loads (extreme and fatigue), siting and energy assessment, noise and grid
  • Define a split between further standards (or updates of standards) required for model validation and conformity assessment documents on model validation
  • Propose the inclusion of the various identified documents (standards and ODs) into the planned work for TC88 and IECRE-Wind respectively
  • The scope of the work is to develop a generic framework for model validation that can be used within the wind energy sector and that gives room for further details on specific topics such as loads model validation (extreme and fatigue loads), power performance model validation, noise model validation, siting and energy assessment model validation, grid model validation and other topics to be defined in the future
  • In order to ensure that the generic model is practically applicable, the first topic that will be worked out in more detail in parallel is validation of the power performance model

REMC Stakeholder Group 553 "End users"
The WE-OMC End User Working Group (SG553) shall be open to stakeholders utilizing the WE-OMC certification schemes who are not involved in testing or manufacturing of wind energy equipment. The SG553 shall focus on issues that provide value to stakeholders within the sector. SG553 stakeholders include: Wind developers, owners, operators, service providers, insurers, financiers, land-owners, authorities having jurisdiction (AHJs), and Agents (e.g. Consultants) acting on the behalf of the aforementioned. In reporting to the WE-OMC, the duties of SG553 are to operate as a stakeholder committee to support the scheme to serve market needs, to build trust and in addition to the Terms of Reference of the WE-OMC, shall:
  • Promote mutual recognition of IEC certificates, test reports, and other documents produced through the scheme;
  • Voice the requirements of the End Users for the certification system;
  • Clarify Market Requirements for the certification process;
  • Provide recommendation to the system to ensure competitive Levelized Cost Of Energy (LCOE) for wind;
  • Encourage improvements in safety and reliability;

REMC Task Force 003 "RETL proficiency testing"
  • To create document(s) for voting (DV) to be submitted to the WE-OMC member bodies that are based on WE-OMC/358/DC, WE-OMC/359/DC and WE-OMC/360/DC
  • To include in this new document, to the extent possible, the comments received as documented in WE-OMC/366/CC. For comments that are not taken on board, the reason/rationale shall be provided as to why these are not taken on board
  • This specifically means that the Task Force shall not create a new document from scratch but continue the already established work and update the existing document with comments received. This specifically means that the task force should not develop further comments on WE-OMC/358/DC. However, some of the comments in WE-OMC/366/CC are rather generic and the task force should discuss these taking into account the viewpoints from the various stakeholder groups and TF members, and achieve consensus on the best way to deal with these comments. The Proficiency Testing OD, the Participation Certificate and the Proficiency Testing Report must then be updated to reflect the consensus achieved
  • Participation in the task force is on nomination by the Member Body, hence the participants are not formally representing the stakeholder groups but are expected to be able to reflect on the viewpoints from the different stakeholder groups for those SG’s in which they are Members
  • To update the related document WE-OMC/359/DC as per comments received and documented in WE-OMC/367/CC as well as based on the more general discussions and decisions in the task force regarding the implementation of comments as per WE-OMC/366/CC
  • To update the related document WE-OMC/360/DC as per comments received and documented in WE-OMC/368/CC as well as based on the more general discussions and decisions in the task force regarding the implementation of comments as per WE-OMC/366/CC
  • The task force shall be automatically disbanded when the Proficiency Testing OD, the Participation Certificate and the Proficiency Testing Report have all been approved by the WE-OMC
REMC Task Force 004 "Model Validation"
  • 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
REMC Task Force 005 "PV Operational Documents"
