Fig. 8. Line Flow Sensitivity Factor for IEEE 118-bus system
The performance of the proposed algorithm is also analyzed by placing TCSC to other potential locations i.e. line-105 and line-106. It has been found that for control parameter setting of TCSC at 0.2973 pu and 0.3051 pu respectively for these two locations of TCSC placement, the congestion is effectively alleviated from the system which can also be observed from power flow results shown in Table 11. The percentage line loading for the considered potential locations of TCSC is illustrated in Fig. 9 which shows that placement of TCSC at these locations alleviates the system congestion.
