Enhancing Power System Security by Proper Placement of Thyristor Controlled Series Compensator (TCSC)

Abstract

In stressed electric power systems, due to increased loading or due to severe contingencies often lead to situation where system no longer remains in the secure operating region. FACTS devices can play very important role in power system security enhancement. Due to high capital investment, it is necessary to locate these devices optimally in the power system. The scope of this paper is to decide optimal location of Thyristor controlled series compensator (TCSC) by a real power flow performance index sensitivity based approach & line outage distribution factor. The effectiveness of the proposed controller has been tested on modified IEEE 30 bus system using Power world simulator software version 12.0.
