This letter studies the impact of the dead-band in the input signal of power system stabilizers (PSSs) on the transient response of power systems. The letter provides a taxonomy of the dynamic behavior of the system in various scenarios: no PSS, PSS without dead-band, and PSS with dead-band. For the latter, the dead-band stability margin and the interaction of the PSS with the system loading level as well as primary and secondary frequency regulators are discussed. The oscillatory behavior of the system is rigorously studied through the monodromy matrix and limit cycles are characterized by means of Floquet multipliers. The IEEE 14-bus system serves to illustrate the aforementioned scenarios.

Abstract
This letter studies the impact of the dead-band in the input signal of power system stabilizers (PSSs) on the transient response of power systems. The letter provides a taxonomy of the dynamic behavior of the system in various scenarios: no PSS, PSS without dead-band, and PSS with dead-band. For the latter, the dead-band stability margin and the interaction of the PSS with the system loading level as well as primary and secondary frequency regulators are discussed. The oscillatory behavior of the system is rigorously studied through the monodromy matrix and limit cycles are characterized by means of Floquet multipliers. The IEEE 14-bus system serves to illustrate the aforementioned scenarios.| File | Dimensione | Formato | |
