Optimal Placement of Thyristor Controlled Series Compensators for Sensitive Nodes in Transmission System Using Voltage Power Sensitivity Index

Abstract

This paper proposes a novel Voltage Power Sensitivity Index (VPSI) to find sensitive nodes for optimal placement of TCSCs. The proposed index is used to rank the buses according to their voltage sensitivity. Taguchi Method (TM) is used to find size of TCSCs to improve voltage stability margin and voltage profile of the system and to cope up the problem of line congestion. The proposed methodology has been tested on IEEE 14-bus test system to substantiate its applicability. 
