Small-signal security assessment considering minimum redispatch

This work presents a review of the main concepts related to electromechanical stability of power systems and of characteristics associated to the voltage, transient and small-signal security assessments (VSA, TSA and SSA). The last one is the focus of this research. The development of new tools for small-signal security assessment and their computational implementations in software PacDyn, from Electrical Energy Research Center (CEPEL), are described. A method for determining minimum redispatch for power systems using generation sensitivities (CSBGRES) is proposed. This is an optimization method that considers a desired damping factor for oscillation modes as constraint. The CSBGRES method can be utilized for the determination of small-signal security margins or of corrective measures, aiming at the dynamic behavior improvement of power systems.
