Optimal allocation of UPFC to minimize real power losses using NSPSO algorithm

Abstract

This paper presents the optimal location of UPFC in Transmission system by implementing a new methodology called NSPSO. With this we can achieve two objectives one is reduction of Real Power loss (RPL) and the other one is improving the bus voltages. In order to identify the optimal location of the UPFC, L-Index strategy is utilized. Moreover the effectiveness of the method is tested on the IEEE 14 bus & IEEE 30 bus system by considering 125%, 150%, 175% and 200% overloading cases. Finally, we can prove that the NSPSO algorithm is the optimal technique for finding the rating and location of UPFC and also improving the system stability.
