Fast, accurate algorithms to compute network capabilities are indispensable for transfer-based electricity markets. Available Transfer Capability (ATC) is a measure of the remaining power transfer capability of the transmission network for further transactions. Transmission System Operators (TSOs) are encouraged to use the existing facilities more efficiently. One of the limitations of reactive ATC is the error produced by neglecting the effect of reactive power flows in line loading. This paper presents the determination of shunt reactive power compensation with Flexible AC Transmission System (FACTS) devices, the Static Synchronous Series Compensator (SSSC) to improve the transfer capability of a power system incorporating the Linear and Reactive power flows in ATC calculations. By redistributing the power flow, the ATC is improved. Studies on a sample 5-bus power system model are presented to illustrate the effect of shunt compensation along with line flow control.
