CHAPTER 2. TOOLS AND SIMULATION RESULTS 32 performance of the test system. Although the system is stable, there is a lightly damped oscillations that could be improved by retuning the controller. 2.3.5 Controller Interactions Among TCSCs and PSSs Figures 2.13 shows some eigenvalues of the system with both TCSC and PSS controllers. The value of KPSS is set to 5 and the compensation ratio for the TCSC controller is 40% in this case. When KPSS is increased to 7, the eigenvalues of the system are shown in Figures 2.15 and 2.14 with and without inclusion of the TCSC controller in the system. Observe the interaction between the PSS and the TCSC, which leads to an unstable operating condition, which is also confirmed by the time domain simulations shown in Figure 2.16. Hence, there is a need for retuning the PSS controller in this case to eliminate the problem generated by the addition of the TCSC controller.
