Optimal Operation of PV Sources in DC Grids for Improving Technical, Economical, and Environmental Conditions by Using Vortex Search Algorithm and a Matrix Hourly Power Flow
(2022-12-26)
This document presents a master–slave methodology for solving the problem of optimal operation of photovoltaic (PV) distributed generators (DGs) in direct current (DC) networks. This problem was modeled using a nonlinear ...
High impedance fault modeling and location for transmission line
(2021-04-07)
A fault in a power system generates economic losses, security problems, social problems and can even take
human lives. Therefore, it is necessary to have an efficient fault location strategy to reduce the exposure
time ...
Nonlinear analysis and control of a reaction wheel pendulum: Lyapunov-based approach
(Elsevier B.V., 2019)
This paper presents a nonlinear analysis, control, and comparison of controllers based on the dynamical model of the reaction wheel pendulum (RWP) in a tutorial style. Classical methodologies such as proportional integral ...
Economic dispatch in DC Microgrids considering different battery technologies: A Benchmark Study
(2020-11-25)
Large penetration of variable renewable sources and electronic loads put short-term stress on microgrids. Energy storage systems account for a reliable way to mitigate these issues. However, depending on the electro-chemistry, ...
A mixed-integer second-order cone model for optimal siting and sizing of dynamic reactive power compensators in distribution grids
(2022-06-20)
The problem of the optimal placement and sizing of dynamic reactive power compensators in AC distribution networks is addressed in this paper from convex optimization. The exact mixed-integer nonlinear programming (MINLP) ...
Global stabilization of a reaction wheel pendulum: A discrete-inverse optimal formulation approach via a control lyapunov function
(2020-10-26)
This paper deals with the global stabilization of the reaction wheel pendulum (RWP) in the discrete-time domain. The discrete-inverse optimal control approach via a control Lyapunov function (CLF) is employed to make the ...
Analysis of the behavior of daily maximum rainfall within the department of Atlántico, Colombia
(MDPI AG, 2019)
In the Colombian Caribbean region, there are few studies that evaluated the behavior of one of the most commonly used variables in hydrological analyses: the maximum daily rainfall (Pmax-24h). In this study, multiannual ...
Isohyetal maps of daily maximum rainfall for different return periods for the Colombian Caribbean Region
(MDPI AG, 2019)
In Colombia, daily maximum multiannual series are one of the main inputs for design streamflow calculation, which requires performing a rainfall frequency analysis that involves several prior steps: (a) requesting the ...

(2023-01-16)
This paper deals with the problem regarding the optimal operation of photovoltaic (PV) generation sources in AC distribution networks with a single-phase structure, taking into consid eration different objective functions. ...
Análisis de la relación entre la conducta de bullying y las funciones ejecutivas en niños y adolescentes escolarizados
(2020-12)
Si bien es conocida la existencia de asociaciones significativas entre las Funciones Ejecutivas (FFEE) y la agresión, el papel de las FFEE en el contexto del acoso escolar o bullying rara vez se ha examinado en poblaciones ...
