dc.description.abstractThe power quality disturbance in a power distribution network was voltage sag and swell and voltage harmonic. New ideas, methods and techniques had been introduced by researchers to improve the quality of supply particularly at the sensitive load end. Many of these methods have their own drawbacks such as complexity, slow response and sensitivity to parameter variations. In this research, an improved Dynamic Voltage Restorer (DVR) topology has been designed and modeled to be used on a 415 Volts distribution network. A seven level cascaded multilevel inverter using multicarrier SPWM technique controller was proposed to handle the voltage imperfections. An innovative controller based on the Synchronous Rotating Reference Frame (SRRF) to overcome the disadvantages of the existing controller schemes by reducing the complexity, number of signal measurements and computing time has been developed. The controller was able to control the zero sequence voltage during unbalance fault period. The switching frequency of the phase shift SPWM was low and hence, the switching loss was low. The Total Harmonic Distortion (THD) with the proposed DVR was significantly reduced to 1.64 % as compared to other traditional models and was within the IEEE Standards 519-2014. The proposed controller algorithm provides excellent voltage compensation. � IEOM Society International.en_US
