In the interest of balance ,
since it seems all yo-yo AWES is to scared or gagged to address an open forum…
we should note there will be other AWES presenters at WESC 2021
@rschmehl Prof Roland Schmehl, the high heed yin of AWES academia will lead a session.
And a session with holistic technology assessment of AWES
will be hosted by Dr Jochem Weber from NREL.

Theme 10: Emerging Technologies and Special Sessions Airborne Wind Energy System Modelling, Control and Optimisation Prof. Roland Schmehl1, Prof. Lorenzo Fagiano2 'TU Delft,2Polytechnic University of Milan Airborne wind energy systems use tethered flying devices for harvesting wind energy. The tethered connecti- on to the ground introduces a large number of degrees of freedom which, on the one hand, require conti- nuous control and present severe challenges for complete automation and reliability, but, on the other hand, also offer many opportunities for optimizing the design and operation of the systems. For example, using a tether drastically reduces the material effort of wind energy harvesting compared to conventional turbines and allows accessing higher altitudes while continuously adjusting to the available wind resource. As a result achievable capacity factors are considered to be higher than for turbines with fixed operational height Driven by the commercial development of airborne wind energy systems, many computational tools and experimental techniques have emerged over the last decade. This Mini-Symposium focuses on contributions in the areas of system modeling, control and optimization of airborne wind energy systems. Covered are also tools for system and component design, reference designs and simulation models, methods for reliability and safety engineering, wind resource modeling, performance analysis, aerodynamic characterization of kites, aeroelasticity as well as operational aspects such as laun- ching and landing. Both theoretical and experimental contributions are welcome. 25-28 MAY HANNOVER, GERMANY
Theme 10: Emerging Technologies and Special Sessions 25-28 MAY HANNOVER, GERMANY Performance Metrics and Technology Assessment of Airborne Wind Energy Systems Dr. Jochem Weber, Dr. Robert Thresher NREL Airborne wind energy systems are at various pre-commercial stages of technology development and a diver- sity of technology archetypes, operational principles and designs are under development As for many resource intensive technology development challenges and especially where a multitude of solution concepts and technological implementations are possible it is critical to acquire a clear, holistic and solution-agnostic formulation of the problem statement in form of stakeholder and functional requirements for all operational modes and over the life-cycle of the system. In order to progress the technology development towards successful realization a multitude of relevant performance characteristics need to be monitored and improved to satisfy the requirements. These may vary from simple performance metrics, through more complex compound trade-offs to comprehensive technolo- gy assessment methods and tools which are supported by simulation tools, validation and testing at compo- nent, subsystems and systems levels as well as by guided expert judgement. This Mini-Symposium will reflect on the state of the art of performance metrics and technology assessment of airborne wind energy systems, identify gaps and address further options to support successful, cost, time and risk effective technology development processes.
