RAMIREZ, M  and  CASTELLANOS, R. Improvement of the dynamic behavior of large-scale power systems by using robust power system stabilizers based on fuzzy logic. Ing. Investig. [online]. 2015, vol.35, n.1, pp.65-70. ISSN 0120-5609.

In this paper, the effect of fuzzy logic-based robust power system stabilizers on the improvement of the dynamics of a large-scale power system is investigated. The study is particularly focused on the Mexican Interconnected System and on adding damping to two critical inter-area system oscillation modes: the north-south mode and the western-peninsular mode. The fuzzy power system stabilizers (FPSSs) applied here are based on a significantly reduced rule base, small number of tuning parameters, and simple control algorithm and architecture, which makes their design and implementation easier and suitable for practical applications. Non-linear time-domain simulations for a set of test cases and results from Prony Analysis verify the robustness of the designed FPSSs, as compared to conventional PSSs.

Keywords : Large-scale power systems; inter-area oscillations; power system stabilizer; fuzzy logic.
