In this paper, the authors present the enhancement of voltage sags, harmonic distortion and low power factor using five-level Distribution STATic COMpensator (D-STATCOM) with LCL passive filter in distribution system. Five-level DSTATCOM is one of the equipments for voltage sag mitigation in power systems. Voltage sag has been considered as one of the most harmful power quality problem as it may significantly affect industrial production. The model is based on the Voltage Source Converter (VSC) principle. The five-level DSTATCOM injects a current into the system to mitigate the voltage sags. LCL passive filter was then added to D-STATCOM to improve harmonic distortion and low power factor.
