Hybrid control approach for fast switching MMCs
The Journal of Engineering, Volume 2019, Issue 17, Page 3933-3936, June 2019., 2019 This study presents a new hybrid control approach for different control and switching frequencies for converters of the modular multi‐level converter (MMC) family. Using this concept, it is possible to achieve a higher switching frequency and output voltage update frequency than the MMC control frequency.

Enhanced Phase‐to‐Phase Distance Protection for AC Lines With Power‐Electronics‐Interfaced Sources
IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.This paper proposes an adaptive enhanced phase‐comparison distance protection (PCDP) strategy to address the maloperation risks caused by high penetration of power electronics‐interfaced sources (PEIS). Unlike the conventional scheme with a fixed operating boundary, the proposed strategy dynamically adjusts the protection zone, effectively capturing ...
