DC Energy Storage Schemes for DVR Voltage Sag Mitigation System

H. P. Tiwari and Sunil Kumar Gupta

Abstract—The Dynamic Voltage Restorer (DVR) is series-connected power electronics based device. It provides technically advanced and economic solution to compensate voltage sag in both transmission and distribution systems. DVR output is determined according to the degree of disturbance in supply voltages. Sag compensation is achieved by injecting the required power into the line through DVR injection transformer. A variety of energy storage devices are used in DVR power circuit for supplying the input to inverter. In this paper, various energy storage devices which are generally used with the DVR power circuit are discussed in detail. Based on the comparative study suitable energy storage devices are suggested for a DVR system.

Index Terms—DVR, Energy Storage Device, Voltage Disturbance.
