Data‐Driven Deep Learning Algorithm for Harmonics and Interharmonics Flicker Prediction and Mitigation in the Smart Grid System

International Transactions on Electrical Energy Systems, Volume 2025, Issue 1, 2025.
In grid‐connected smart distribution systems, the prediction and mitigation of flicker caused by harmonics and interharmonics present a significant challenge for stable grid operation, particularly in the presence of distributed renewable energy sources (DRESs).

Control System of an SVC Based on ARMA Model to Improve the Displacement Power Factor of an Electric Arc Furnace

Journal of Electrical and Computer Engineering, Volume 2025, Issue 1, 2025.
In the steel industry, electric arc furnaces (EAFs) are essential for metal scrap recycling. However, they are known for their high reactive power consumption, negatively impacting power quality (PQ). The static VAR compensator (SVC) is the reactive power compensation device that provides the best cost‐benefit relation for mitigating the impact of EAFs.

RETRACTED: Cross‐country high impedance fault diagnosis scheme for unbalanced distribution network employing detrended cross‐correlation

IET Generation, Transmission &Distribution, Volume 18, Issue 24, Page 4192-4208, December 2024.
The cross‐correlation technique was used in this study to recover the complex, aperiodic, asymmetric, and non‐linear properties of the signals during cross‐country faults with high impedance fault syndrome. Due to its reduced sensitivity to background fluctuations, a given change may not affect all of the component peaks.

The Extent and Limitations of Correlating Measured Interharmonics and Measured Voltage Fluctuations [PDF]

, 2015
Amplitude modulation is a well-known cause of voltage fluctuations resulting in luminous lamp flicker. Amplitude modulation can be more generally quantified in terms of interharmonics. The theoretical correlation between interharmonics and lamp flicker

Induction Motors Under Voltage Unbalance Combined with Voltage Subharmonics

Energies
In power systems, various power quality disturbances are present, including voltage deviation, voltage unbalance, and voltage waveform distortions. Voltage waveform distortions are usually identified with harmonics, but in some systems, subharmonics ...

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.
