    • A Convex OPF Approximation for DC Networks Considering Voltage-Dependent Load Models 

      Gil-González, Walter; Garcés, A.; Casilimas-Peña, A.; Garrido Arévalo, Víctor Manuel; Montoya, Oscar (Cartagena de Indias, 2020-12-01)
      This paper addresses the problems of power flow and optimal power flow analysis considering voltage-dependent load models from the convex point of view. First, Taylor series expansion method is employed for linearizing the ...

    • Determination of the Voltage Stability Index in DC Networks with CPLs: A GAMS Implementation 

      Amin W.T.; Montoya O.D.; Grisales-Noreña L.F. (Springer, 2019)
      This paper addresses the voltage collapse analysis in direct-current (DC) power grids via nonlinear optimization approach. The formulation of this problem corresponds to an optimization problem, where the objective function ...

    • Hybrid ga-socp approach for placement and sizing of distributed generators in DC networks 

      Montoya, Oscar Danilo; Gil-González, Walter; Grisales-Noreña, Luis Fernando (Cartagena de Indias, 2020-12-02)
      This research addresses the problem of the optimal location and sizing distributed generators (DGs) in direct current (DC) distribution networks from the combinatorial optimization. It is proposed a master–slave optimization ...

    • Optimal location and sizing of distributed generators in dc networks using a hybrid method based on parallel pbil and pso 

      Grisales-Noreña, Luis Fernando; Montoya, Oscar Danilo; Ramos-Paja, Carlos Andrés; Hernandez-Escobedo, Quetzalcoatl; Perea-Moreno, Alberto-Jesus (Cartagena de Indias, 2020-11-01)
      This paper addresses the problem of the locating and sizing of distributed generators (DGs) in direct current (DC) grids and proposes a hybrid methodology based on a parallel version of the Population-Based Incremental ...

    • Optimal Power Flow in Direct Current Networks Using the Antlion Optimizer 

      Garzón Rivera O.D.; Ocampo, J.A; Grisales-Noreña, Luis Fernando; Montoya, O.D; Rojas-Montano, J.J. (Cartagena de Indias, 2020-10-06)
      This document presents a solution method for optimal power flow (OPF) problem in direct current (DC) networks by implementing a master-slave optimization methodology that combines an antlion optimizer (ALO) and a power ...

    • Optimal Power Flow on DC Microgrids: A Quadratic Convex Approximation 

      Montoya O.D.; Gil-González, Walter; Garces A. (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 ...
