Building Hurricane-Resilient Urban Grids by Climate-Informed System Hardening Optimization
Mr Shuo Li, City University of Hong Kong
Abstract: Climate-driven hurricanes pose escalating threats to urban electricity distribution networks, undermining energy security and community wellbeing. A key challenge lies in developing integrated resilience strategies that effectively address emerging climate patterns—including fewer but more intense hurricanes and increasingly prevalent compound wind-rainfall hazards—alongside the spatial heterogeneity of risks and diverse vulnerabilities across urban and rural contexts. This seminar presents ongoing research efforts focused on building hurricane-resilient urban grids through climate-informed optimization frameworks. Specifically, the presentation will cover three complementary themes: (1) Long-term grid hardening and modernization, where high-resolution hurricane modeling is integrated with synthetic distribution networks to enable exposure-tiered reinforcement strategies that optimize infrastructure investments according to spatially diverse risk profiles; (2) Pre-event resilience planning, which addresses compound wind-rainfall hazards and trajectory uncertainties through stochastic optimization of emergency measures tailored to distinct urban-rural network characteristics; and (3) Post-disaster resilient restoration, which explores the integration of social vulnerability metrics alongside economic factors to achieve more equitable and effective recovery outcomes. Through interdisciplinary integration of electrical engineering and earth science, this work aims to contribute practical frameworks for enhancing grid resilience in hurricane-prone regions.
Speaker's Bio: Shuo Li received the B.S. degree in electrical engineering from Tianjin University, Tianjin, China, in 2023. He is currently pursuing dual Ph.D. degrees with the Department of Electrical Engineering, City University of Hong Kong, and the School of Electrical and Information Engineering, Tianjin University. His research interests include modeling and optimization of hurricane impacts on urban grids, resilience assessment and planning, and interdisciplinary integration of climate science and power systems engineering.

Resilient Control and Stealthy Attack for Neworked Switched Systems
Abstract:
This presentation focuses on resilient control and stealthy attack design for networked switched systems, addressing critical cybersecurity challenges in cyber-physical systems (CPS). The work addresses these challenges through a comprehensive framework that includes attack detection, system resilience, and attack strategy analysis. 1) Developed a new method to detect different types of cyberattacks. 2) Designed a defense strategy to counteract DoS attacks and deception attacks which fully utilizes the switching signal. 3) Devised stealthy attacks for switched systems when considering that the switching signal is unknown.

Optimal Control of Hydrogen Fuel Cells
Abstract:
This seminar focuses on the application of advanced machine learning techniques in the optimal control of hydrogen fuel cells. The proposed methods possess the merits of superior control performance, model independence, low computational burden, and guaranteed closed-loop stability, which make them attractive for industrial applications that require robustness under uncertainty and low computational cost.
