The Dynamic Voltage Restorer (DVR) is a custom power device that is mainly used for mitigation of voltage sags. The aim of this paper is to investigate and compare different control techniques for this device. In particular, the main focus of the paper is on optimal use of the energy storage. First, the adopted control structure for the DVR will be presented. Then, different strategies for voltage sag mitigation will be described. Among all, the Energy Optimized Compensation (EOC) method will be investigated in detail. Simulation results of EOC method will be presented. Finally the comparison between the EOC and other methods will be shown.

Nyckelord: dynamic voltage restorer, energy optimize compensation, voltage sag, voltage source converter
