The researchers are more importance to power quality problems. Various power quality problems are voltage sag, voltage swell, harmonics, interruptions etc. This paper proposes to reduction the Total Harmonic Distortion (THD) in power system. The total harmonic distortion is reduced using distribution static compensator (DSTATCOM). An Instantaneous d-q theory has been used for controlling switching converter which calculates the required current injected into the power system. The simulated results show the effectiveness of DSTATCOM in reducing the harmonic distortion.
