Abstract :

This paper presents analytical method to find optimal location of FACTS device in power system. The loadability limit of the system is found by observing constraints like bus voltage, line loading and voltage angle while doing incremental changes in generation and load. As Thyristor Controlled Series Compensator (TCSC) is having good capabilities for enhancement of loadability, TCSC is introduced, when any of constraints is violated. The performance of TCSC is verified for each anch except anch containing tap–changing transformer. The loadability is found for the system without TCSC and after introducing TCSC in every anch (one line at a time). Simulation using MATPOWER is done on IEEE–14 bus system. The performance of TCSC is analyzed for all probable 17 locations of IEEE–14 bus system by analytical method.
