The rapid rise of people is causing significant issues in the electricity system by increasing energy consumption or load demand. In Power System, there are several problems cause of overloading issues, dangerous blackouts, voltage fluctuations, and collapse. A system's voltage profile will be better as a result of improved reactive power compensation, raising the system's overall power quality. In this paper, the power quality analysis examined case study i.e. Standard IEEE 9 bus system describes the During-fault, and Post-fault conditions using DSTATCOM device carried out with MATLAB software. The pre-fault condition is accomplished using the power flow study by the Newton-Raphson method, and the influence of a three-phase balanced fault has been deliberated during-fault conditions. The IEEE-9 bus system was first examined using standard test data, and subsequently the same system was examined using D-STATCOM. The system's reactive power compensation, voltage profile, and line losses with and without D-STATCOM are all investigated.Also this paper presents a comparative analysis of IEEE 9 bus system power quality analysis using D-STATCOM device with respect to without DSTATCOM device to improve system performance.
