Biography: Chul-Hwan Kim is an IEEE Fellow and earned his B. S., M. S., and Ph. D. degrees in electrical engineering from Sungkyunkwan University, Seoul, Korea, in 1982, 1984, and 1990, respectively. He started his career as a lecturer at Jeju National University, Korea in 1990. In 1996, 1998, and 1999, he was a visiting academic professor at the University of Bath, U.K. Currently, he serves as a professor at School of Electrical and Electronics Engineering of Sungkyunkwan University, Seoul, Korea, and holds position of director of the center for power information technology.
He was technical program committees co-chair of IPST(International conference on Power System Transients) 2023 and the local program committee chair of IPST 2017.
He was president of Power Engineering Society of KIEE and Korea Institute of Electrical Engineers (KIEE, 50th) in 2018 and 2021, respectively. From 2018 to 2021, he served as a review board member of the National Research Foundation (NRF) of Korea.
Furthermore, since 2008, he is a member of technical review panel of an international conference on Developments in Power System Protection (DPSP) organized by IET, U.K. Furthermore, he serves as an esteemed editorial board member for IEEE Power and Energy magazine, International Journal of Electrical Power & Energy Systems (IJEPES), and Protection and Control of Modern Power Systems. Additionally, he holds the role of an editor in Electrical Power Systems Research (EPSR) at Elsevier. His research includes power system protection, transients, distributed renewable generation, and analysis and protection of MVDC, and LVDC systems.
Speech Title: AC/DC Hybrid Distribution Systems
Abstract: As DC power sources and DC loads are connected to the power system on a large scale, the conventional AC distribution systems are reaching their limitations. In response, medium-voltage DC (MVDC) distribution systems are emerging as an alternative for the next-generation distribution system. In Republic of Korea, the goal is to operate an AC/DC hybrid distribution system by 2030, and partially replacing existing AC distribution system with DC distribution system is being considered. With the same conductor and insulation ratings, a DC line can transmit roughly twice the power of an AC line. Medium-voltage DC (MVDC) distribution is also expected to substantially increase the hosting capacity for renewable resources, DC sources, and DC loads. Operationally, MVDC avoids frequency-related stability constraints, experiences lower voltage drop and reduced losses because reactive power is absent, enables more efficient integration of DC sources and loads through direct interconnection, and improves overall asset utilization by enabling controllable power flows via power-electronic converters.
