This paper presents an propagation integral synchronous reference frame (PI-SRF) based effective control for DSTATCOM to mitigate various power quality issues in 3P3W distribution network. The proposed SRF based control found to be effective in maintaining DC-link voltage to its reference and estimate fundamental weight components of load currents for generating reference current. These reference currents are compared using actual source currents through hysteresis current controller (HCC) and generate six controllable gate signals. These controllable gate signal further utilized by DSTATCOM to enhance the power quality in distribution network. The proposed PI-SRF based effective control is capable to regulating the voltage, harmonics elimination, and balancing the loads for wide variety of loads at the PCC of 3P3W distribution network.
