Abstract: In this paper, a Dynamic Voltage Restorer (DVR) for the sags and swells compensation from 10% to 90% and power factor correction in distribution systems is proposed. The voltage sags are not always possible to prevent due to the finite time compensation of faults that causes voltage drops to spread to sensitive loads in electrical systems. The DVR model is based on a Voltage Source Converter (VSC) scheme for voltage compensation due to the presence of sags of amplitude ranging from 0.1 pu to 0.9 pu and swells with amplitude from 1.1 pu to 1.9 pu. The results obtained through MATLAB & Simulink® are verified.
