Meta‐Optimized Twin Delayed DDPG Reinforcement Learning Agent for Multiobjective Control of Shunt Active Power Filters

Electronics Letters, Volume 62, Issue 1, January/December 2026.
A PSO‐aided TD3 agent is proposed to automate the neural topology design for active power filters, replacing manual tuning with algorithmic discovery. By converging on the minimal sufficient architecture, the framework slashes computational overhead by over 50%, enabling rapid offline retraining suitable for digital twin‐based adaptive grid control ...

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

Real‐Time Implementation of Unknown Input Observer‐Based State and Unknown Disturbance Estimation for Series Active Filters

International Journal of Circuit Theory and Applications, Volume 53, Issue 7, Page 3970-3992, July 2025.
For the series active filter (SAF), a combined controller and observer scheme is proposed. Two controllers—state feedback (SFB) and linear quadratic regulator (LQR)—along with state observers, including the Luenberger observer (LO), proportional–integral observer (PIO), and unknown input observer (UIO), have been designed.
