Optimum Location of Thyristor Controlled Phase Angle Regulator Based on Performance Index

Nowadays the overloading of the transmission lines are increased due to which different types of faults and the main issue i.e., voltage collapse may occurs which affect the stability of the system. Thus the main objective of the system operator is to maintain the system in steady state limit. Flexible AC Transmission System (FACTS) devices plays a vital role in maintaining the power system stability, reducing the overall system losses and controlling the power flow in the system. But it is very necessary to investigate the optimal location of these FACTS devices for their satisfactory operation. In this paper, the optimum location of the thyristor controlled phase angle regulator (TCPAR) has been figure out in the system based on real power flow performance index (PI). The test case of IEEE -5 bus system is to be considered and the power flow of the system is carried out by using MATLAB. The results of MATLAB are verified with the power world simulator 12.0 software.
