Abstract
With the widespread application of power electronic devices, the harmonic pollution generated by these devices has become a significant threat to power quality in electrical grids. To address this issue, this study investigates harmonic suppression techniques for power electronic devices and their applications in power grids, aiming to improve power quality and ensure stable grid operation. By integrating theoretical analysis with simulation experiments, this research delves into the principles, characteristics, and applicable scenarios of active filters, passive filters, and hybrid filters. An innovative hybrid filtering scheme based on adaptive control algorithms is proposed, which can dynamically adjust filter parameters to accommodate varying operating conditions. Verification through MATLAB simulations and field measurements demonstrates that the proposed scheme exhibits superior harmonic suppression performance compared to traditional methods, particularly in reducing total harmonic distortion. This approach effectively enhances the reliability and stability of power grids, offering new insights into harmonic mitigation for power electronic devices and contributing significantly to the development and advancement of smart grids.
