Sensitivity based ATC Maximization by Optimal Placement of TCSC applying Grey Wolf Optimization

The deregulation of the power industry resulted in the participation of the private sector, which reduced the rates of electrical supplies to end-users but on the other hand it increases the congestion in the power system due to overloading of the transmission lines. To mitigate congestion many cost-free and non-cost free methods are used. Congestion in the power system can be minimized effectively by enhancing the Available transfer capability (ATC) of the transmission line. This paper demonstrates sensitivity-based analysis to enhance ATC by incorporating TCSC on the standard IEEE 30 Bus system. Sensitivity factor ACPTDF is used to search the location of the device and the size of TCSC is optimized by the Grey Wolf Optimization Algorithm (GWO). The detailed method to locate and optimize TCSC for reducing system power losses and increasing Available Transfer Capacity (ATC) is demonstrated in this paper. The utility and superiority of GWO are illustrated here on the system and are detailed with the help of a suitable table and figures.
