LADRC‐based non‐characteristic harmonic suppression strategy for pumped storage power plants
Electronics Letters, Volume 60, Issue 20, October 2024.This letter proposes a control strategy based on linear active disturbance rejection control (LADRC) to alleviate the delay triggering angle α non‐characteristic harmonics caused by transient disturbances. The validity of the conclusion was verified through on‐site data collection, theoretical analysis, and simulation verification.

IET Generation, Transmission &Distribution, Volume 18, Issue 14, Page 2464-2479, July 2024.This study is important for industrial enterprises with non‐linear electrical loads and allows them to accurately identify the contributions of internal distortion sources, regardless of the harmonic presence in the supply electrical grid. In turn, this method also makes it possible to identify the share contribution of external harmonic sources. A new
