Application of Adaptive filters in Dynamic Voltage Restorer for Power System Harmonics Estimation

Abstract

In this literature, the dynamic voltage restorer (DVR) using voltage injection approach is used to dynamically restore the load voltage. The restoration process is based on the state and quality of the utility system, which supplies energy injection to the external system during voltage sags and absorbs energy from the external system during voltage swells, causing a rise in the DC link voltage that is connected across the voltage source inverter (VSI). In this study, the functioning of DVR is examined with an ADALINE based LMS (A-LMS) algorithm control technique as opposed to the traditional RLS algorithm. The MATLAB/SIMULINK tool is used to design, develop, and authenticate various findings under various load situations, and the outstanding features are established.
