The research team of Jiyu Lee, Jonghun Yoon, and Jaekeun Lee from the Power Conversion Systems Laboratory (supervised by Professor Seung Hui Cui) received the Best Paper Award at the IEEE Power Electronics for Distributed Generation Systems 2025 (PEDG 2025), organized by the IEEE Power Electronics Society (PELS).

The research team gave an oral presentation on the topic “Ultra-Fast Black Start Method for Grid-Forming Converters in Electronic Power Grid with Transformer Soft-Magnetization” during the special session titled “Grid-Forming Session.” This study was a collaborative effort with Professor Jaejeong Jeong’s lab at Kyungpook National University and Professor Heng Wu’s lab at Aalborg University in Denmark. It proposed a novel method to actively control transformer flux during Black Start using inverter resources after a blackout in large-scale power systems. This approach prevents inrush current and dramatically reduces the Black Start time from tens of seconds to the sub-millisecond range.

At PEDG 2025, a total of 227 papers were presented; only 10 were shortlisted for the award, and just 3 were ultimately selected as Best Papers.

Now in its 16th year, the IEEE PEDG—launched in 2010—has become a flagship international conference in power electronics for distributed generation. Each year, hundreds of researchers and industry experts attend to share the latest results and collaborate on renewable energy integration technologies and next-generation power conversion systems.
