Nonlinear loads inject harmonics in the power system and distorts the load current waveform. These load current harmonics ultimately give rise to harmonics on the supply side and hence can affect the neighboring consumers. Custom power technology is employed to avert issues of power quality on the source side. Among numerous custom power tools, Distribution Static Compensator (D-STATCOM) is considered to be an effectual Shunt Active Power Filter to banish current harmonics, providing a good balance between cost and performance. A control strategy based on Instantaneous Reactive Power (IRP) theory for D-STATCOM is discussed in this paper. D-STATCOM is controlled to compensate for reactive power and to discard the objectionable harmonics injected in the distribution system by nonlinear load. Anti-harmonics current is inserted in the grid lines by the mentioned Shunt Active Power Filter, which nullify the harmonics introduced by the nonlinear load. To be used for the nullification of current harmonics, D-STATCOM is connected parallel with the load. Moreover, the power factor of the system is ameliorated along with a significant decrease in Total Harmonic Distortion (THD) in the source current. The model is simulated in MATLAB/SIMULINK in order to investigate the performance and efficiency of the propounded system. The simulation results reveal expeditious dynamic response and high precision of D-STATCOM in achieving the desired goals.
