This paper proposes a best possible distribution of Thyristor Controlled Series Compensator (TCSC) to progress the Available Transfer Capability (ATC) of power transactions between sources and sink areas in the deregulated power system.The principle of TCSC device is to balance the inductive dragon ball lg disney voltage drop in the line by an introduced capacitive voltage or in other words to alleviate the effective reactance of the transmission line to improve ATC in the network.The objective of the optimization is to find the preeminent location and parameters of TCSC devices by means of Flower Pollination Algorithm (FPA) for maximizing ATC and minimizing power losses and installation cost of TCSC device.The estimate of ATC using AC Power Transfer Distribution Factors (ACPTDF) based on the Newton Raphson power flow technique.

The ACPTDFs are the consequent using sensitivity based approach for the system intact case and utilized to check the line flow limits during ATC fortitude.The efficacy of the proposed method is icon track bar f250 demonstrated using an IEEE-30 bus test system for the evaluation of ATC in normal and line outage contingencies conditions for the preferred bilateral, multilateral and area wise transactions.The simulation outcome illustrates that the introduction of TCSC devices in an accurate location could increase ATC, fall in total losses and advance the line congestion as compared to the system without TCSC devices.
