Large-scale Use of FACTS Technology for Damping Inter-Area Oscillations in the Mexican System

Improvement of the dynamic behavior of large-scale power systems by using robust power system stabilizers based on fuzzy logic

“…Based on a dynamic model of the MIS for a 2004 test base case, with no PSSs in the system, the characteristics of these oscillation modes have been determined and are given in Figure 2 (Castellanos et al, 2007). Considering the structure of the MIS in Figure 1, inter-area mode 1 is associated with the interaction of machines between the northern and southern regions; inter-area mode 2 involves mainly machines in the W area swinging against machines in the P region, and inter-area mode 3 denotes the interaction of machines in the W area oscillating against machines in the SE region.…”

“…In this regard, different alternatives like the installation or retuning of conventional PSSs on main machines of the system, use of automatic load and generation shedding schemes, application of HVDC technology, and exploitation of supplementary controllers on installed FACTS devices have been suggested (Messina et al, 2003;Castellanos et al, 2007). At this point, the study is directed to the analysis and evaluation of the potential benefits of the previously described simple fuzzy PSS, when fitted on key machines of the MIS.…”

“…Extensive studies performed on the system (Messina et al, 2003;Castellanos et al, 2007) reveal that the loss of critical transmission lines has a considerable impact on the overall system response. For the present study and in order to illustrate the performance and robustness of the SFPSSs, and evaluate their effectiveness in enhancing the damping of inter-area oscillation modes of the MIS, the following contingencies were selected:…”

“…Extensive studies in Castellanos et al, 2007, involving modal analysis and time domain simulations, identify the generating units at CBD and SYD power stations in the NE and N regions, respectively, and the machines at MDP power plant in the P region, as some of the major generators that could yield important improvements in the damping of inter-area oscillations through the application of supplementary stabilizing controls. Therefore, they were selected to be equipped with SFPSSs.…”

Issues affecting the electricity transmission and distribution system in México

“…Over the last few years, several SVCs have been installed in the Mexican system to improve transient stability and dynamic voltage regulation [17]- [ 19]. Primary advantages of SVCs application include steady-state voltage regulation and transient stability enhancement [16].…”
