Review of Voltage Sag/Swell Mitigation Techniques with Dynamic Voltage Restorer in a Grid Integrated Distribution System

EasyChair Preprint no. 8711

Abstract

Voltage disturbances in power distribution systems  caused by the integration of renewable energy sources can be efficiently minimized with the use of the Dynamic voltage restorer (DVR). DVR is an efficient custom power device that is used in power systems to mitigate voltage disturbances. The DVR's performance is determined by its maximum voltage injection capability and the amount of energy stored in the restorer. Enhancement in the control technique of this non-linear device (DVR) is required to improve its efficiency. To efficiently regulate DVR, Synchronous reference frame Theory (SRF), Artificial Neural Networks (ANN), Integrated Sliding Modey Controller (ISMC), Fuzzy logic, and a variety of other control approaches have been developed. This paper gives a comprehensive review of voltage quality challenges, as well as the different DVR-based control strategies used in reducing voltage sag and swell in power networks along with their advantages and disadvantages.
