An approach to evaluate the occurrence of flicker induced by electromechanical oscillations

In this paper, an approach to evaluate the occurrence of flicker induced by electromechanical oscillations is proposed. This approach employs the extended participation factors (EPF) to statistically quantify the presence of electromechanical modes in the dynamics of the terminal voltage of a distributed synchronous generator. Once the results obtained by the EPF indicate a high probability for the manifestation of the electromechanical mode in the terminal voltage of the distributed generator, an estimate for the probability of occurrence of flicker can be obtained.
