The voltage sag and swell in the medium and low voltage distribution grid are considered to be the most frequent type of power quality problems based on recent power quality studies. Their impact on sensitive loads is severe. For sensitive loads, even voltage sag of short duration can cause serious problems in the entire system. Normally, a voltage interruption triggers a protection device, which causes shutdown of the entire system. The work presented in this paper is confined to voltage quality identification and mitigation for sag and swell. The work carried out concentrates on the development of simplified suitable devices for mitigation of voltage sag and swell. Many of the suitable devices such as D-STATCOM, UPQC and DVR are available to mitigate voltage sag and swell problems. Among these, Dynamic Voltage Restorer (DVR) can provide the most commercial solution to mitigate voltage sag by injecting voltage as well as power into the system. Dynamic Voltage Restorer is a series connected power electronics based device that can quickly mitigate the voltage sag and swell in the system and restore the load voltage. Energy storage devices used in this work Battery for DVR and it is responsible for supplying active power needed during voltage sag and swell. In this work control objective like, simple abc control algorithm based PSO is proposed. It is to utilize the error signal to control the triggering of the switches of an inverter using Pulse Width Modulation (PWM) technique. Modeling and simulation of proposed DVR control is implemented in MATLAB /SIMULINK software and results are presented
