IEA Task 48 WP2: Survey Results

Kurzfassung

The IEA Wind Task 48 is a platform for the open exchange of ideas, experience, and techniques of Airborne Wind Energy Systems (AWES). In work package 2, the goal is to develop a set of reference models, tools and metrics for simulating AWES. This work package is starting by creating a taxonomy of AWES models. What are the different engineering disciplines considered in different models (e.g. aerodynamics, dynamics, etc.)? How are these different disciplines modeled (e.g. aerodynamic coefficients, lifting-line aerodymics etc.)? How are the different models meant to be used (e.g. exploring optimal control law, evaluating load statistics, etc.)? How the existing software tools fit within this taxonomy (FAST, AWEBOX, etc.)? This taxonomy will be used to influnce future work within the task. First, the task aims to create a set of benchmarking excercises to help validate the different models. The task aims to take a bottom up approach by validating individual disciplines and eventually moving up to multi-disciplinary models. The taxonomy can identify the important disciplines to validate, the range of modelling methods that need to be tested and help define a test case that challenges all the existing codes. Second, the task aims to develop a standard representation for simulation and design data. Such standards can help facilitate collaboration by giving a common language for sharing design and simulation data. It can also allow one to couple complimentary simulation tools, from different developers, provided that both exchange information through a common format. The same taxonomy will help define this standard. The taxonomy is being developed through a combination of literature review and consultations with acadamia and industry. It's important that input from the whole sector is reflected in this taxonomy, this presentation will cover the current progress thus far, however at the same time we want to invite the audience to give their feedback and get involved in this effort.
