Publication Information Abstract This study presents a multi-body dynamic modeling approach for exploring and optimizing the novel co-location design of ocean-based renewable energy systems and aquaculture fishery systems. As both systems expand offshore to meet global energy and food demands, competition for limited oceanic space has become a growing concern. The co-location of these two distinctive systems offers a solution to this challenge by combining them in overlapping geographical locations while addressing their respective objectives and constraints. The study introduces …

Dr. Yong Hoon Lee was presented with the Outstanding Lecture Award from the Korean-American Scientists and Engineers Association at the YGNITE 2023, with the topic of “Enabling Design of Floating Offshore Wind Energy Systems.”
The objective of this project is the development of a hierarchical control co-design (H-CCD)formulation, specifically applied to the floating vertical-axis wind turbine (FloatVAWT) systemdesign as a strategy to enable achievement of aggressive LCOE targets. Vertical-axis windturbines (VAWTs) have significant potential in achieving low-cost floating offshore wind turbine(FOWT) systems based on their inherent characteristics favorable to the marine environmentbecause they have lower vertical centers of gravity and aerodynamic pressure, demandingsmaller and less expensive floating platforms.

Experimental analysis on the hydrokinetic turbine systems provide data for identifying and validating model parameters for the horizontal axis hydrokinetic turbines in the context of design optimization. It is crucial to optimize the HAHkT scale, external and internal geometry, rotor and blade design, and control scheme simultaneously to achieve cost-efficient energy conversion. However, high-fidelity simulation models, such as three-dimensional computational fluid dynamics (CFD), are costly, making the reduced-order model (ROM) approach more practical in the optimization loop. In this study, …
