Posters
Come meet the poster presenters to ask them questions and discuss their work
We would like to invite you to come and see the posters at our upcoming conference. The posters will showcase a diverse range of research topics and provide an opportunity for delegates to engage with the authors and learn more about their work. Whether you are a seasoned researcher or simply curious about the latest developments in your field, we believe that the posters will offer something of interest to everyone. So please, join us at the conference and take advantage of this opportunity to learn and engage with your peers in the academic community. We look forward to seeing you there!
PO083: Hybrid wind and wave platform in MOST
Ermando Petracca, Scholarship, Politecnico di Torino
Abstract
In this article, different integrated WEC and floating platform concepts are studied. The coupled dynamics, the structural behavior, and the energy production of the WEC and the wind turbine are analyzed. An in-house numerical model, named MOST, is used for this purpose. MOST is written in MatLab-Simscape environment and allows the user to evaluate the multi-body dynamics in six degrees of freedom using the Simscape libraries offered by WEC-Sim, developed by a collaboration between NREL and Sandia; the hydrodynamic properties of the bodies are obtained from Nemoh, an open-source software. The different concepts are compared based on the Levelized cost of energy (LCOE) for a selected offshore site, and the forces measured at the tower base. The reference wind turbine is the DTU 10 MW with ROSCO controller. The WEC concepts examined in this article are the point absorbers and oscillating water column devices. The differences between the point absorber and OWC device with different geometries and the control logic are discussed. The LCOE, the impact on the tower's fatigue, and the platform's overall size are compared.
