Abstract: In this paper, Compensator is a flexible ac transmission system (FACTS) controller, which can either absorb or deliver reactive power to a power system. Distribution Static Compensator (D STATCOM) is proposed to compensate for reactive power and unbalance caused by various distribution system loads. The static distribution compensator is based on the VSC principle. A D STATCOM injects a current into the system to correct the voltage sag, swell and power factor. Distribution Static Synchronous Compensator (D- STATCOM) is an effective measure to maintain voltage stability and improve the distribution grid's power quality. This paper deals with the modeling and control scheme of D-STATCOM. Stability analysis of D- STATCOM is obtained by bode plotapproach.
