On the use of the p-q theory for harmonic currents cancellation with shunt active filter
(VSB-Technical University of Ostrava, 2019)
Discussion and mathematical proof on necessary and sufficient conditions for the application of the p-q theory for compensating the harmonic currents consumed by non-linear load using a shunt active filter are presented. ...
Distributed energy resources integration in AC Grids: A family of passivity-based controllers
(Universitat Politecnica de Valencia, 2019)
This paper presents the design and application of passivity-based control theory for distributed energy resources (DERs) integration through voltage source converters (VSC) in ac single-phase grids. The Hamiltonian ...
Optimal Power Flow on DC Microgrids: A Quadratic Convex Approximation
(Institute of Electrical and Electronics Engineers Inc., 2019)
This express brief shows a convex quadratic approximation for the optimal power flow (OPF) in direct-current microgrids (dc-μ Grid) via Taylor's series expansion. This approach can be used for solving OPF problems on radial ...
Solution of the optimal power flow problem in direct current grids applying the hurricane optimization algorithm
(2019-09-24)
The Colombian electrical power system is being transformed by the large-scale integration of energy storage systems and renewable energy resources to the power system. These technologies can be integrated using alternating ...
Vortex Search Algorithm for Optimal Power Flow Analysis in DC Resistive Networks With CPLs
(2019-08-30)
This express brief addresses the optimal power flow (OPF) analysis in direct-current (DC) resistive networks with constant power loads (CPLs). The OPF employs the vortex search algorithm (VSA) in conjunction with a power ...
Triangular Matrix Formulation for Power Flow Analysis in Radial DC Resistive Grids With CPLs
(2019-07)
This brief briefly addresses the problem of power flow solution for direct-current (dc) networks with radial configuration and constant power loads (CPLs). It proposes a novel iterative method based on the upper triangular ...
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 ...
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 ...
Early characteristics and predictors of clinical severity in Autism Spectrum Disorder
(Universidad CES, 2019)
Significant efforts have been made to detect Autistic Spectrum Disorder (ASD) during the first years of life, with positive effects on the prognosis of children. However, in countries such as Colombia early identification ...
