Abstract: Providing power to the consumers without interruption and maintaining voltage, frequency and power factor within nominal values is said to be power quality. One of the major emerges for power engineers is a power quality problem such as harmonics, voltage sags, voltage swell, unbalance and many more. These power quality burdens may impact the consumer devices and even roots to damage the devices connected. FACTS devices fit for the solution for this issue, and in this paper, DSTATCOM was used to reduce the harmonics in source components. This paper presents a rationalized control to produce gate pulses to DSTATCOM for power quality improvement in the distribution system. The offered Source Current Reference Control (SCRC) algorithm for DSTATCOM is simple and eliminated complex transformations and calculations. The standardcontrol strategies sensed load currents for harmonic computations and to generate reference currents. The control strategy introduced in this paper sensesthe source current for reference in the control algorithm. The mentioned control strategy verified for fixed, variable load and linear load conditions in a power system. The considered concept developed,and results are obtained using MATLAB/SIMULINK software.
