Synergistic Paradigm for Second Harmonic Current Redistribution and Energy Optimization in Power Supply System via Time-Frequency Modeling

The utilization of harmonic energy and precise quantification of energy distribution represent critical challenges in advancing modern power supply system. This article presents a synergistic paradigm for dynamic second harmonic current redistribution and energy optimization in hybrid power supply system through time-frequency modeling approach. By introducing the adaptive masked Wigner–Ville distribution to the paradigm, the proposed method provides high-resolution time-frequency models in second harmonic current compensator to precisely capture harmonic behavior. The model guides dynamic current redistribution, balancing harmonic compensation with optimal energy usage through a multiobjective optimization strategy. Experimental validation demonstrates the effectiveness of the proposed method in balancing harmonic compensation and energy efficiency. This article offers a novel synergistic paradigm for harmonic compensation and energy optimization, contributing a highly cost-effective and scalable solution to the advancement of hybrid power supply system.
