Non‐Contact Turn‐Off Time Measurement Method for IGBTs in the Half‐Bridge Submodule Configuration of MMC

open access: yesIET Power Electronics, Volume 19, Issue 1, January/December 2026.
This paper proposes a non‐contact method for measuring the turn‐off time of insulated‐gate bipolar transistor (IGBT) devices in modular multilevel converters (MMC) submodules, using the decay of load‐side common‐mode current. The technique leverages existing current‐sensing infrastructure and avoids intrusive modifications, enabling real‐time ...

Coordinated Planning of Flexibility Resources for HVDC‐Connected Renewable Base and Load Center: A CVaR‐Based Probabilistic Approach

open access: yesIET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.
This paper proposes a conditional value‐at‐risk (CVaR)‐based coordinated planning framework to address the volatility and uncertainty in high voltage direct current (HVDC)‐interconnected systems. By jointly optimizing storage deployment, thermal retrofits, and reserve allocation, the method effectively quantifies and mitigates tail risks.
