Performance Comparison of VSI Based DSTATCOM and ZSI Based DSTATCOM in A Distribution System Network

D-STATCOM (Distribution Static Compensator) is a shunt device which is generally used to improve power quality of distribution systems. It is a device applied for correcting power factor, maintaining constant distribution voltage and mitigating current harmonics in a distribution network. In this paper, effort has been made to use ZSI based D-STATCOM in distribution system and its performance has been compared to VSI based DSTATCOM. The MATLAB/SIMULINK models have been developed to draw the conclusions.
