Flexible AC transmission systems devices can play very important role in enhancement of power
system security. Thyristor Controlled Series Capacitor (TCSC) is one of the important FACTS devices that can
change smoothly and rapidly its apparent reactance according to the system requirements. In this paper it is
initially introduced a new method to allocate the optimum installation place of one or more TCSCs. The target
function to determine the TCSCs installing place is increasing voltage stability during fault contingency. After
determining TCSCs optimum installation place, their success rate in buses voltage stabilization is studied by
a new following index, voltage stability index, and it is presented that they can be greatly effective in voltage
stability. TCSC installation effect on amount of load shedding reduction is also presented as a new subject to
keep buses voltage stability. IEEE 14&30 bus power systems are selected as the studied systems and mentioned
analysis are applied on this system.
Key words: Power system stability, series FACTS devices, Thyristor Controlled Series Capacitor (TCSC), , , ,
