When evaluating power quality, voltage is a critical influencing factor. Voltage quality is typically assessed by measuring voltage deviation, fluctuation, waveform distortion, and three-phase symmetry—with voltage deviation being the most important indicator. To ensure high voltage quality, voltage regulation is generally required. Currently, the most widely used and effective method for voltage regulation involves adjusting the tap changer of power transformers.This paper primarily integrates
