A technique is introduced to improve the voltage sag under sudden changes in load. The proposed technique is implemented by D-STATCOM (Distribution static compensator) and it is controlled by ISCT (Instantaneous Symmetrical Component Theory). Due to sudden changes in load, the voltage dip occurs at the time of switching of loads. At this time, the control technique generates reference currents and hysteresis block compares these currents with the reference currents and generates the pulses to D-STATCOM. Implementation of system along with compensation is carried out in MATLAB/SIMULINK
