DSTATCOM is a custom power device that is used to regulate the voltage sags/swells in the distribution system for maintaining the rated voltage level at the terminal of load/sensitive loads. The DSTATCOM can inject three-phase voltages at point of common coupling whose magnitude and phase angle can be regulated with PI controller, while the super capacitors are used to meet the instantaneous power demand since they can store and quickly release significant amounts of energy. This paper explores the use of Super capacitors in DSTATCOM in place of battery for control of load terminal voltage
