Load-Aware Hybrid Power-Quality Control for 440-V Shipboard Grids: PSO-Tuned SC–TCR with Tuned LC and Right-Sized Active Filtering.

This work presents a load-aware hybrid power-quality control strategy for 440-V shipboard electrical grids. The proposed approach integrates a particle swarm optimization (PSO)-tuned static compensator–thyristor controlled reactor (SC–TCR), tuned LC passive filters, and a right-sized active power filter to mitigate harmonic distortion, reactive power imbalance, and voltage fluctuations under variable shipboard loading conditions. The control framework dynamically adapts compensation levels based on real-time load characteristics, ensuring compliance with IEEE 519 harmonic standards while minimizing converter rating, losses, and system complexity. The hybrid configuration exploits the strengths of passive and active compensation techniques, achieving improved total harmonic distortion, enhanced power factor, and stable voltage regulation across a wide operating range. Simulation results validate the effectiveness of the proposed method compared with conventional fixed and oversized compensation schemes, demonstrating superior performance and robustness for modern shipboard power systems.
