Performance Analysis of Eleven Bus System

This paper present performance of fed Eleven bus power system and UPFC system. We are modeled and simulate using Matlab/Simulink. The performance analysis of voltage sag and voltage swell in the Eleven bus uncompensated system. In this paper UPFC has been developed using shunt and series device. It is the capable of improving transient stability of power system. UPFC is control the flow of real and reactive power by voltage in series with the transmission line. In this paper we determine Load voltage, load current, real and reactive power waveforms show UPFC results. In a recent time many research paper are working in Fourteen bus system, Five bus system and many more but now in this paper we perform analysis of Eleven bus system.
