Optimal Placement of UPFC and SVC in Power Systems Using DAPSO Algorithm for the Improvement of Loadabilityand Voltage Profile

This paper proposes optimal location of FACTS devices in power system using Dynamic Adjustment Particle Swarm Optimization (DAPSO) algorithm. From the FACTS devices family, shunt device static var compensator (SVC) and unified power flow controller (UPFC) are considered. The choice of the appropriate place and size is one of the important issues in the application of SVC and UPFC in voltage profile, loadability and stability enhancement. The proposed DAPSO algorithm is a very effective method for the optimal choice and placement of SVC and UPFC devices to improve the voltage profile, loadability and voltage stability of power systems. The proposed algorithm has been applied to IEEE 30 bus system. The results show that the performance of power system can be effectively enhanced due to the optimal location and parameters of the SVC and UPFC.
