Abstract

The performance of the electrical power system is directly affected by the disturbance of power quality standards, and one of the most important of these disturbances that affect the performance of the power system is the voltage sag that affects the voltage of sensitive loads as it can lead to the generation of a large magnetic impulse current, system failure, increased losses, especially in industrial loads and thus increase the cost.

Dynamic Voltage Restorer DVR is one of the best and optimum methods used with the power system to reduce voltage sag. The optimal design of the dynamic voltage restorer with inverter control using a suitable design of the PI controller can improve the performance of the DVR by reducing the dynamic response time and thus reducing the sag voltage in the power system.

In this research study, we propose a DVR control technology using a PI controller with a serial and parallel controller to optimize the power quality. The proposed control technique can act as voltage compensation in a single-phase or three-phase system.

This study was carried out using Matlab simulation software to model the PI controller with a DVR to control the power system.

The results that we obtained in this study show the great superiority of the proposed control technique in improving the quality of power during periods of voltage sag.
