Unified Power Flow Controller in 5-Bus Power System Study and Simulation

This paper provides an overview of the Flexible Alternating Current Transmission System FACTS devices, especially on unified power flow controller (UPFC) integrates properties of both shunt and series compensations, and can effectively alter power system parameters in a way that increases power transfer capability and stabilizes the system, where it was placed in the electric grid 5-Buses focuses, in order to test the effect of his ability to control the transmitted power between the stations and also ability to install efforts, it was presented the results of the network with and without UPFC, using MATLAB program, where proved results capacity to control his ability and install efforts.
