In this paper a new algorithm is proposed for a DSTATCOM operating in voltage control mode to generate reference voltage. The proposed scheme ensures that unity power factor (UPF) is achieved at the load terminal during nominal operation, which is not possible in the traditional method. The compensator here is also used to inject lower currents so that the losses in the feeder and VSI are reduced. Further rating of DSTATCOM can also be reduced so that it mitigates the voltage sag. Nearly UPF can be maintained at the load terminal during load change. Due to the above reasons the DSTATCOM increases the power quality by improving power factor, harmonic reduction, and tight voltage regulation. Simulation results are presented to determine the efficiency of the proposed algorithm of DSTATCOM.
