Optimal Location and Parameter Settings of UPFC Device in Transmission System based on Imperialistic Competitive Algorithm

Abstract

In this paper, we present a new method to determine the optimal location and parameter settings of Unified<br />Power Flow Controller (UPFC) for removing voltage violations and transmission lines overloading. UPFC is<br />considered as the most powerful member of the FACTS devices, that it can control shunt and series power flow.<br />This option gives to UPFC the power to control the voltage profile and transmission lines flow simultaneously.<br />We used the Imperialistic Competitive Algorithm (ICA) to determine the optimal location and optimal parameter<br />settings of UPFC to improve the performance of the power system specially removing voltage violations in the<br />buses and solving transmission lines overloading to increase loadability in the power networks. This procedure<br />is proposed to be applied on IEEE 14 bus system to show the validity of the method.
