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


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