Stabilization of MT-HVDC grids via passivity-based control and convex optimization
(Elsevier Science SA, 2021-07)
This paper presents a model for stabilizing multi-terminal high voltage direct-current (MT-HVDC) networks with constant power terminals (CPTs) interfaced with power electronic converters. A hierarchical structure of ...

Direct power control of electrical energy storage systems: A passivity-based PI approach
(Elsevier Ltd, 2019)
This paper proposes a direct power control for electrical energy storage systems (EESS) in ac microgrids. This strategy allows managing instantaneous active and reactive power without using a conventional inner-loop current ...
Control Methods for Single-phase Voltage Supply with VSCs to Feed Nonlinear Loads in Rural Areas
(Cartagena de IndiasCampus TecnológicoIngeniería Electrónica, 2020-12-17)
This paper addresses the problem of sinusoidal voltage generation in linear loads using a voltage source inverter (VSI). The port-Hamiltonian structure in open-loop is used to design a passivity-based controller with ...
Voltage and Frequency Regulation on Isolated AC Three-phase Microgrids via s-DERs
(IEEE Computer Society, 2019)
This paper addresses the voltage regulation problem on isolated three-phase microgrids via passivity-based control (PBC) with a proportional regulator under the abc reference frame. This reference frame is employed to ...
Direct power control for VSC-HVDC systems: An application of the global tracking passivity-based PI approach
(Elsevier Ltd, 2019)
This paper proposes a direct power control (DPC) for a high-voltage direct-current system using voltage source converters (VSC-HVDC) by applying passivity-based control theory. This system allows doing an efficient and ...
Control Methods for Single-phase Voltage Supply with VSCs to Feed Nonlinear Loads in Rural Areas
(Universidad Tecnológica de Bolivar, 2020-12)
Este artículo aborda el problema de la generación de voltaje sinusoidal en cargas lineales utilizando un inversor de fuente de voltaje (VSI). La estructura port-Hamiltoniana en lazo abierto se utiliza para diseñar un ...
Symbiosis between quantum physics and machine learning: Applications in data science, many-body physics and quantum computation
(Universidad Nacional de ColombiaBogotá - Ciencias - Doctorado en Ciencias - FísicaFacultad de CienciasBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá, 2022-12-01)
This thesis explores the intersections between quantum computing, quantum physics and machine learning. In the three fields, estimating probability distributions plays a central role. In the case of quantum computing and ...
