A study of TCSC optimal damping control parameters for different operating conditions

This paper illustrates the use of a cost function or performance measure to carry out a sensitivity analysis on the Slatt Thyristor Controlled Series Capacitor (TCSC). The sensitivity analysis performed revealed that a choice of controller parameters for optimal system damping are dependent upon the system loading level and configuration. This result suggests that by tuning the control parameters of the TCSC controller for the various system conditions encountered on the power system a significant improvement in system damping may be obtained.
