Title： Future Power System Structure and Development Strategy in Southern China
Abstract：Increasing load density and cross-regional power transmission are posing growing challenges for future power system planning and operation. This keynote reviews typical topologies and functions of transmission systems, and analyzes the general evolution patterns. It outlines medium to long-term development strategies of transmission systems across five provinces in Southern China, and presents the key supporting technologies.
Bio：LIU Zhengchao received the B.Eng.degree and M.Eng. degrees in electrical engineering from Tsinghua University, beijing, China, in 1999 and 2002. After graduation, he joined CSG Guangdong Power Grid Corporation to engage in power grid dispatching, operation and planning work, and currently serves as the director of main grid planning research institute in energy development research institute, CSG. His interests include power system balance, large-scale renewable energy absorption analysis, power grid stability analysis, transmission grid structure planning and investment decision-making.
Title：Key Issues Faced in Power System Planning and Operation in the Context of Renewable Energy Growth
Abstract：The first section primarily elaborates on the development status of the domestic and international power industry, including the China Southern Power Grid (CSG), against the backdrop of renewable energy expansion. The second section provides a detailed analysis of four critical challenges in power systems: grid structure, balance, safety risks, and electricity market dynamics; concluding with an exposition on technological advancement directions for operational risk prevention and control.
Bio：CHEN Binbin, She earned her Master’s degree in Advanced Power Systems Engineering from the University of Manchester and currently works at the Energy Development Research Institute of China Southern Power Grid, focusing on power grid planning and system operation analysis. She previously worked for over six years in the Guangxi Power Grid Dispatching and Control Center, engaged in dispatch and operation. She is currently primarily responsible for the Southern Power Grid’s Three-Year Grid Operation Analysis, Three-Year System Design, power system interconnection, and system connection review.
Title：Economical Solutions for Suppressing Transient Overvoltage in Renewable Energy Outward Transmission
Abstract：With China’s large-scale new energy development, resource-abundant regions transmit clean energy to facilitate its consumption. However, concentrated transmission induces transient overvoltage, endangering grid safety. This report analyzes its mechanism, proposes an economical “distributed + hydroelectric modulation” solution, now applied domestically.
Bio：ZEGN Qin received the B.Eng.degree in electrical engineering from Chongqing University of Posts and Telecommunications, Chongqing, China, in 2015, and the M.Eng. degree in power system and its automation from Sichuan University, Chengdu, in 2021. Then, she joined Southwest Electric Power Design Institute Co., Ltd. of CEEC, where she was engaged in power system planning and design. At the end of 2024, she served as an assistant researcher in Energy Development Research Institute, CSG. Her research interests include inter-regional UHVDC transmission planning, generation optimization of large-scale clean energy bases and national power flow layout.
Title：AI-based Probabilistic Assessment in New-type Power Systems for Operational Planning
Abstract: Greener-growing new-type power systems face increasingly severe safety challenges. This presentation presents an attempt to perform planning from a probabilistic perspective—namely, to assess power grid frequency security risks arising from the uncertain output of renewable energy in operational planning—while leveraging AI-based methods for efficient assessment.
Bio：WEN Jiaxin received the B.Eng.degree and M.Eng. degrees in electrical engineering from Northeast Electric Power University, Jilin, China, in 2012 and 2015, respectively, and the Ph.D. degree in electrical engineering from Hong Kong Polytechnic University, Hong Kong, in 2021. Then, he served as Postdoctoral Researcher in Hong Kong Industrial Artificial Intelligence and Robotics Centre, and Hong Kong Polytechnic University, subsequently. After that, he joined CLP Power Hong Kong as an engineer and currently he is an assistant researcher in Energy Development Research Institute, CSG. His research interests include probabilistic assessment and mitigation in operational planning, AI-based evaluation algorithm, demand response, power supply and demand coordination research.
