Enhancement of Available Transfer Capability with facts device in competitive power market

In order to facilitate the electricity market operation and trade in the restructured environment, ample transmission capability should be provided to satisfy the demand of increasing power transactions. The conflict of this requirement and the restrictions on the transmission expansion in the restructured electrical market has motivated the development of methodologies to enhance the available transfer capability (ATC) of the existing transmission grids. The insertion of FACTS devices in electrical systems seems to be a promising strategy to enhance ATC. In this paper, the viability and technical merits of boosting ATC using thyristor controlled series compensator (TCSC) is being analyzed. The work has been carried out on sample 6 bus and IEEE 30 bus systems. particle swarm optimization (PSO) algorithm is employed to obtain the optimal settings of TCSC and the results obtained are quite encouraging.
