Allocation of Unified Power Flow Controller(UPFC) through sensitivity approach for Enhancing the system performance

In a Modern power system network, Congestion may occurs due to lack of coordination between demand and supply so as to increase the stress on the existing transmission utilities. The system no longer operates within its thermal limit. Unified power flow controller (UPFC) plays a very important role in the power network to enhance the performance of existing lines as well as to improve the security of the system. UPFC should be located optimally due to high capital investment. In this paper, the allocation of UPFC is obtained by sensitivity based approach in terms of change in active power flow sensitivity index so as to enhance the system performance and The test results has been implemented in the MATLAB with modified IEEE 30 bus network and the performance of the system is validated by Power World Simulator Software 16.0.
