The dynamic voltage restorer (DVR) is controlled by a five-level flying-capacitor multi level converter is used to decrease the power-quality disturbances in distribution system, such as voltage imbalances, harmonic voltages, and voltage sags. DVR injects voltages in the distribution line to maintain the voltage profile and assures constant load voltage. The simulations were conducted in MATLAB/Simulink to show the DVR-based proposed strategy's effectiveness to smooth the distorted voltage due to harmonics. The systems' response for load voltage is evaluated for with and without DVR scenarios. It has been noted that the proposed DVR based strategy has effectively managed the voltage distortion, and a smooth compensated load voltage was achieved. The Dynamic Voltage Restorer (DVR) is fast, flexible and efficient solution to voltage sag problem and handles both balanced and unbalanced situations without any difficulties and injects the appropriate voltage component. From simulation results also show that the DVR compensates the sag/swells quickly and provides excellent voltage regulation.
