Abstract—In this paper an attempt has been made to determine Available Transfer Capability (ATC) with the FACTS device i.e. TCSC. The methods for ATC evaluation are developed considering system thermal limits constraints based on MVA loading of the system. Power Transfer Distribution Factors (PTDF) are used to determine the maximum ATC that may be available across the system in a certain direction without violating line thermal limits. ATC traditionally uses linear methods capable of predicting distances based on thermal limits. However, these methods do not consider bus voltages and static collapse. Most of the studies relating ATC involve contingencies and multi-pattern scenarios that often can only be performed in reasonable time with the use of linear methods. In this paper, a new approach is proposed that first determines the Reactive Power Flows using the exact circle equation for the transmission line complex flow, and then evaluates ATC using active power distribution factors. The effectiveness of proposed method is successfully demonstrated on IEEE 30-Bus system.

Index Terms—ATC, PTDF, TCSC, Reactive Power.
