This paper presents the analysis of Ultra capacitor (UC) energy storage device interfaced with Dynamic Voltage Restorer (DVR) for fast mitigation of deeper and extended voltage sags using MATLAB/Simulink® software package. [1] The model is designed with a user-friendly icon and a dialog box like Simulink block libraries. Power quality issues are analysed in detail and ―Voltage Sag in distribution systems is taken for a case study. A new model of Ultra capacitor is proposed and is verified experimentally. Simulation results for Ultra capacitor model are also derived and are found in exact accordance to the experimental modelling. [2] A complete study of Dynamic Voltage Restorer and its simulation using two control strategies viz. d-q-o algorithm and PI controller algorithm is done. To interface Ultra capacitor with DVR, a buck-boost converter controlled with hybrid control algorithm is proposed. Numbers of simulations are carried out on distribution ―Test System and mitigation of voltage sag is observed in each case. The simulation results prove the advantages of the proposed system over the conventional system in terms of fastness sag depth and sag extension. The final results are going in the favour of DVR + UC system. The proposed method, if implemented practically will help the distribution system to improve power quality and can serve the customers in a better way.
