The Distribution static synchronous compensator (D-STATCOM) is a power electronic based shunt connected Flexible AC transmission system device which exchange reactive power to the load for improving the voltage stability of the load busses. The Distribution static synchronous compensator is capable of reducing the losses and improving the voltage regulation in Multi Bus systems. The Distribution static synchronous compensator injects a current into the system to reduce the losses. The Distribution static synchronous compensator is capable of enhancing the reliability and quality of power flow in low voltage distribution network. A Distribution static synchronous compensator is one of the new generation flexible AC transmission system devices with a promising feature of applications in power system. The Distribution static synchronous compensator is used to stabilize the system voltage by exchanging reactive power with the power system. Fifty Bus System with multiple STATCOMs is modeled and simulated. The improvement in voltage stability with Distribution static synchronous compensator is presented. Voltages at various buses with and without Distribution static synchronous compensator are also discussed
