Abstract :Abstract. The emersion of critical loads in industrial, commercial, and domestic applications including power electronic equipments, computers, microprocessors, florescent lamps, and non-linear loads such as induction furnaces in distribution networks has made the subject of power quality one of the distribution system’s main concerns. Any disturbance in the distribution system’s power quality can lead to the disturbance in the operation of these loads and consequently leading to time loss and financial cost. Any deviation or unwanted change in the voltage, current, or frequency of the electricity which causes failure or dysfunction of the electrical equipments is called power quality or better to say weakness in the power quality. A unit of SMES will be introduced in this paper to improve the quality of power during voltage sag and swell. The convertor and the chopper of the SMES unit are respectively controlled via a PID controller and a Fuzzy logic controller.
