Abstract: With the recent trends towards deregulating power systems around the world, transfer capability computation emerges as the key issue to a smoothly running power market with multiple transactions. Enhancement of available transfer Capability (ATC) is an important topic in current deregulation environment considering loop flows and heavily loaded lines. The thermal limits of transmission lines, voltage bounds of buses and upper and lower limits of generator power are considered. In this paper, optimal placement of the STATCOM is found based on Linear Sensitivity Index (LSI). The Modified IEEE 30-bus test system is selected to illustrate the placement of STATCOM and enhancement of ATC by using PSAT software version 2.1.8.

Keywords: Available Transfer Capability, TTC, Linear Sensitivity Index, PSAT.
