Generalized Energy Functions for a Class of Third-Order Nonlinear Dynamical Systems

Autor: Hsiao-Dong Chiang, Luis F. C. Alberto, Daniel S. Siqueira, Newton G. Bretas

Publikováno v: IEEE Transactions on Automatic Control. 66:3111-3122

Nonlinear dynamical systems exhibiting complex structure in their limit sets, such as chaotic and closed orbits, do not admit energy functions. The theory of generalized energy functions, which may assume positive derivative in some bounded sets, app

Direct method for transient stability assessment of a single wind turbine generator subject to LVRT requirements

Autor: Adriano Lima Abrantes, Luis F. C. Alberto, Alexandre Prodóssimo Sohn

Publikováno v: IET Generation, Transmission & Distribution. 14:6195-6205

The authors report on a step towards the development of direct methods for transient stability assessment of power systems with integrated wind turbine generators subject to low voltage ride-through constraints. In this study, they propose an approac

Avaliação de Índices de Estabilidade de Tensão para Utilização em Sistemas de Medições Fasoriais

Autor: Geovane Michael Lentz, Luis F. C. Alberto

Publikováno v: Anais do Simpósio Brasileiro de Sistemas Elétricos 2020.

A busca por metodologias para avaliar a estabilidade da tensão em tempo real é atualmente um dos maiores desafios para os pesquisadores. Alguns autores usaram medições da \emph{Phasor Measurement Unit} (PMU) para calcular índices e monitorar o q
