Optimizing Power Quality: A Comparison of Harmonic Control Methods

This paper explores different harmonic control modes in Active Dynamic Filters (ADFs), focusing on both Current and Voltage Control methods. While Current Control remains the most common method for harmonic mitigation, Voltage Control - through Sensorless and Impedance Control, offers additional flexibility, particularly in complex grid environments. The paper discusses the benefits and limitations of each approach, highlighting scenarios where one method may be preferable over another. A comparative analysis demonstrates how a hybrid strategy, combining multiple control modes, can optimize harmonic mitigation, improve power quality, and enhance system stability in diverse applications.
