A grouping strategy for reinforcement learning-based collective yaw control of wind farms
Theoretical and Applied Mechanics LettersReinforcement learning (RL) algorithms are expected to become the next generation of wind farm control methods. However, as wind farms continue to grow in size, the computational complexity of collective wind farm control will exponentially increase with

Boosting Conversion Efficiency in Zn3P2/InP Solar Cells Via Nanoscale Junction Engineering
Advanced Functional Materials, EarlyView.This study demonstrates the efficacy of selective area epitaxy (SAE) in enhancing the conversion efficiency of a Zn3P2${\rm Zn}_3{\rm P}_2$/InP heterojunction solar cell. The impact of the SAE pattern dimensions on the performance parameters is investigated. Small size opening limits Jsc because of current crowding whereas large size opening limits Voc

Actor Critic Agents for Wind Farm Control
2023 American Control Conference (ACC), 2023 The power output of a wind farm is influenced by wake effects, a phenomenon in which upstream turbines facing the wind create sub-optimal conditions for turbines located downstream. Yaw misaligning strategies have been shown to increase total production.
