Power Quality Enhancement in Grid‐Connected Photovoltaic Systems Using Hybrid Harbor Seal Whiskers Optimization and Interpretable Generalized Additive Neural Networks

International Transactions on Electrical Energy Systems, Volume 2026, Issue 1, 2026.
The integration of solar energy into modern power grids supports sustainability and energy efficiency but also introduces power quality (PQ) challenges such as harmonic distortion, voltage sag, swell, and fluctuations. In order to reduce PQ problems in renewable energy systems (RESs), this research proposes a novel hybrid control strategy that combines
