Impact Of Facts Device For ATC Enhancement In Deregulated Market

Abstract

In restructured electricity market the market participants wants to maximize their profit so try to obtain the electrical energy from the cheapest source. It may lead to congestion in the transmission network which will affect the system reliability and security. In this paper, the sensitivity based methods like, DC power transfer distribution factor (DCPTDF) as well as AC power transfer distribution factor (ACPTDF) are used for IEEE-6 bys system simulation. The optimal location of TCSC (Thyristor control series capacitor) has found through performance index of each line. Results of ATC are obtained in normal operating condition as well as contingency conditions without TCSC and with TCSC. This may practical solution for decreasing expansion planning issues and new transmission lines structural issues.
