Seminar on "From Networked Multi-Agent System to Physical Traffic Computing" by Dr. Kai Fung Chu

Date: 13 December 2024, Friday Time: 4:30pm Venue: CD 634, The Hong Kong Polytechnic University Zoom Meeting ID: 383 735 6917 Password: 270831 Speaker: Dr. Kai Fung Chu, University of Cambridge, UK   From Networked Multi-Agent System to Physical Traffic Computing Dr. Kai Fung Chu, University of Cambridge, UK   Abstract: The capabilities of multi-agent systems are influenced by their underlying network dynamics. Computational intelligence plays a pivotal role in enhancing their performance by reconfiguring the networks, yet it often depends on computation resources in centralized or decentralized devices. Addressing the computational resource constraints could significantly scale up a multi-agent system. In this talk, I will first present how to control the network dynamics for collective goals by showing my research works that exemplify the network reconfiguration process. Then, I will present how an alternative computation resource could be induced by the intrinsic dynamics within a mobile multi-agent system, supported by concrete examples. Finally, I will discuss future research directions in harnessing dynamics-induced computation resources of multi-agent systems.   Speaker’s Bio:Kai-Fung Chu is a Marie Skłodowska-Curie Fellow in the Department of Engineering, University of Cambridge. He received the Ph.D. degree in Electrical and Electronic Engineering from The University of Hong Kong, and the M.Sc. (Distinction) and B.Eng. (First Class Honors) degrees in Electronic and Information Engineering from The Hong Kong Polytechnic University. Prior to joining the University of Cambridge, he was a Research Assistant Professor at the Department of Computing, The Hong Kong Polytechnic University, and a Research Fellow of the School of Aerospace, Transport and Manufacturing, Cranfield University. He also worked in the industry as an engineer for several years. His research interests include multi-agent systems, mobile robots, autonomous vehicles, and intelligent transportation systems.   WEBINAR WEBSITE: https://www.ee.cityu.edu.hk/~cccn/webinar/

Date: 6 December 2024, Friday Time: 4:30pm Venue: YEUNG-B5311, City University of Hong Kong Zoom Meeting ID: 859 2865 1236 Password: 123456 Speaker: Miss Zhenxi Wu, City University of Hong Kong   Comprehensive Analysis Framework for DC Electrical Networks: Evaluating Existence, Algorithm Convergence, Stability of Equilibrium Miss Zhenxi Wu, City University of Hong Kong   Abstract: Stability analysis programs are essential tools for power system planning and operations engineers, allowing them to forecast the system’s response to various disturbances. The outcomes of these stability studies inform critical conclusions and decisions. In this talk, we will present a comprehensive analysis framework to guarantee the correct operation of DC electrical network with large-scale renewable distributed generators (DGs) and constant power loads (CPLs). In addition to an overview, new results are offered. Firstly, analytical solvability conditions based on fixed point theorems for the power flow equation are given and compared, and the strongest analytical solvability condition is presented. Secondly, we obtain the convergence condition about the initial iterative value of Newton-Raphson method for power flow calculations. Thirdly, we extract the intrinsic characteristics of the Jacobian Matrix of the DC electrical network and derive the sufficient local stability conditions. Finally, we propose an algorithm of ROA estimation with less computations and complexity to analyze the transient stability of the system. Speaker’s Bio: Zhenxi Wu received the B.Eng. degree in electrical engineering and automation from Central South University, Changsha, China, in 2020. She is currently pursuing the Ph.D. degree with the Department of Electrical Engineering, City University of Hong Kong and the Ph.D. degree in control science and engineering, Central South University. Her current research interests include stability analysis of power electronic-based power systems and control of power electronics converters.
