A Hybrid Artificial Intelligence Method for Estimating Flicker in Power Systems
This work addresses flicker estimation in power systems, which is important for power quality monitoring, but it appears incremental as it combines existing techniques (H filtering and ADALINE) in a novel way for a specific domain.
The paper tackles the problem of estimating flicker components in power distribution systems by introducing a hybrid AI method combining H filtering and ADALINE networks, which achieves superior accuracy, robustness, and reduced computational load compared to existing methods like Fast Fourier Transform and Discrete Wavelet Transform.
This paper introduces a novel hybrid AI method combining H filtering and an adaptive linear neuron network for flicker component estimation in power distribution systems.The proposed method leverages the robustness of the H filter to extract the voltage envelope under uncertain and noisy conditions followed by the use of ADALINE to accurately identify flicker frequencies embedded in the envelope.This synergy enables efficient time domain estimation with rapid convergence and noise resilience addressing key limitations of existing frequency domain approaches.Unlike conventional techniques this hybrid AI model handles complex power disturbances without prior knowledge of noise characteristics or extensive training.To validate the method performance we conduct simulation studies based on IEC Standard 61000 4 15 supported by statistical analysis Monte Carlo simulations and real world data.Results demonstrate superior accuracy robustness and reduced computational load compared to Fast Fourier Transform and Discrete Wavelet Transform based estimators.
