Lee Research Group partnering with Ecobee, a leading smart thermostat company, to leverage the world’s most extensive energy utilization dataset

Ecobee, a leading smart thermostat company, gathered and organized a substantial dataset on energy utilization voluntary contributions from their smart thermostat customers. Through this partnership, we anticipate that our energy system optimization research, utilizing models based on real-world data, will have a significant impact in combatting climate change by effectively addressing real-life energy consumption patterns. We are grateful to Ecobee for generously sharing their invaluable database with us.

Wind Energy with Integrated Servo-control (WEIS) Project Highlighted by UofM Research + Innovation Newsletter

Our research on developing Wind energy with Integrated Servo-control (WEIS) toolset is highlighted by the University of Memphis Research + Innovation Newsletter. https://www.memphis.edu/research/impact/newsletter_2024/april24_stories/wind_energy_with_integrated_servo_control.php [Newsletter PDF] [Article PDF] Wind Energy with Integrated Servo-Control Floating offshore wind turbines, innovative renewable energy systems Floating offshore wind turbines are a relatively new technology designed to harness wind energy in deep-water regions where conventional fixed-foundation turbines are impractical. They offer several advantages over fixed foundation counterparts, including access to higher wind speeds and more expansive …

Austin Griffin Successfully Defended His Master’s Thesis

Austin Griffin successfully defended his Master’s thesis. Congratulations to Austin for your graduation! Thesis Title Experimentally Supported Reduced Order Modeling for Hydrokinetic Energy System Design Abstract This research advances the field of hydrokinetic energy by introducing a novel control design approach, termed duct contraction control strategy (DCCS), that dynamically optimizes the power output of ducted horizontal axis hydrokinetic turbines (HAHkT). Focusing on the adjustment of duct contraction ratios (CR) and blade pitch in response to varying flow conditions, this strategy …

Prof. Yong Hoon Lee presented Multi-Body Modeling for Conceptual Design of Co-Located Ocean Renewable Energy and Aquaculture Systems at the ASME 2023 IDETC-CIE Conference

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 …
