Feasibility Study for STATCOM’S Capacitor Selection for Voltage Sag Mitigation

Abstract

 I. INTRODUCTIONECENTLY and during the current and last decades, electronic equipment and devices are spreadly used. These are sensitive to electrical supply voltage disturbances. Also, with the extensive penetration of renewable energy sources in electrical systems, power quality becomes an important issue.Voltage sag is a common disturbance caused due to the reclosers to clear non-permanent faults [1].The voltage sag location in the electrical system is crucial in choosing and developing of voltage sag mitigation strategy. The different methods for improving power quality should be evaluated as cost and the expected achieved performance improvements it provides. With the costs of the different voltage sag mitigation methods and the expected benefits, a study of the various mitigation scenarios yields to a better quick return for the investment [2].Mitigating devices and the integration of DG in the electrical distribution system has an impact on the power flow
