Chaotic vibrations of a nonideal electro-mechanical system
(Elsevier B.V., 2001-03-01)
Nonideal systems are those in which one takes account of the influence of the oscillatory system on the energy supply with a limited power (Kononenko, 1969). In this paper, a particular nonideal system is investigated, ...

Fault location in power distribution systems considering a dynamic load model
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ingeniería, 2015-06-01)
In the electrical power systems, load is one of the most difficult elements to be represented by an adequate mathematical model due to its complex composition and dynamic and non-deterministic behavior. Nowadays, static ...
Auto-tuning of PV controllers to improve the speed response and stability of the P and O algorithm
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ingeniería, 2015-06-01)
This paper proposes an auto-tuning control system to ensure a fast response of the photovoltaic (PV) voltage by reducing the perturbation time of a P and O algorithm. This solution accelerates the tracking of the maximum ...
A biólogical context for theta-frequency neuronal resonance: a comparative study between cortical amygdala and hippocampal neurons
(2015)
Neurons from different memory-related mammalian brain regwns display intrinsicmaximal subthreshold voltage responses to oscillatory stimulation at theta frequencies(4-12Hz; theta resonance). This may contribute to tune and ...
Análise de estabilidade rotórica e de frequência em sistemas elétricos de potência utilizando o programa ANATEM: simulações e estudos de casos
(Universidade Tecnológica Federal do ParanáCuritibaBrasilGraduação em Curso de Engenharia ElétricaUTFPR, 2016-06-14)
Maintaining power systems stability is essential to achieve uninterrupted supply of electric energy with quality. This task is extremely complex due to the innumerous perturbations to which these systems are continuously ...
Development of a computer vision image recognition tool for underwater wet welding
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA MECÂNICAPrograma de Pós-Graduação em Engenharia MecanicaUFMG, 2022-07-22)
The focus of this work is to analyze the dynamics of the bubbles resulting from the welding
process, on the effect of different formulations of coated electrodes, in both polarities and
varying the welding current. The ...
On some dynamic properties of electrical power systems : sobre algunas propiedades dinámicas de los sistemas eléctricos de potencia
(2010)
This thesis treats some dynamic properties of power system models. An extension of the classical concept of dissipativity is formulated to deal with these systems described by differential-algebraic equations on phasor ...
Bilinear Control for Three-Phase Microgrids: A Proportional-Integral Passivity-Based Design
(Cartagena de IndiasCampus Tecnológico, 2020-07-30)
A bilinear PI control based on passivity theory for the adequate integration of distributed energy resources (DERs) in ac microgrids is presented in this paper. DERs are integrated into the grid by voltage source converters ...
