Power Quality (PQ) has become a critical issue in highly automated industries and sensitive load centers. The voltage quality is the most important part of the PQ for customers. The voltage disturbances in the form of voltage sag, swell, flicker and harmonics can cause huge financial losses. In the past few years, power electronic solutions have been proposed to avoid these problems. Custom power devices also called as power quality compensator employ power electronic or static controllers in medium or low voltage distribution systems for the purpose of supplying a level of power quality that is needed by electric power customers.
