• Unified Power Flow Controller (UPFC)
• Maximize the Loadability of Transmission Lines
• Modified Shuffled Frog Leaping Algorithm (MSFLA)

In this paper a new method called "Modified Shuffled Frog Leaping Algorithm" is used to obtain optimal location and number of FACTS devices in a power system. Among the FACTS devices, Unified Power Flow Controller (UPFC) enables the active and reactive power flow and bus voltages to be controlled simultaneously due to its great flexibility. Decoupled model of UPFC is applied to maximize the system loadability considering transmission line capacity limits and specified voltage level. The Shuffled Frog Leaping Algorithm (SFLA) is a new meta heuristic algorithm with a global search capability which uses efficient mathematical function. The objective is to maximize the transmission capability and loadability subject to the transmission line capacity limits and specified bus voltage levels. Location of the UPFCs and their parameters will be optimized simultaneously by using the proposed method The proposed method (SFLA) is tested on IEEE 14-bus, 30-bus and IEEE 118-bus systems. The simulated results show that the steady state performance of the power system can be improved effectively due to the optimal location and parameters of the UPFC.
