    • On Linear Analysis of the Power Flow Equations for DC and AC Grids with CPLs 

      Montoya Giraldo O.D. (Institute of Electrical and Electronics Engineers Inc., 2019)
      This express brief presents an approximation of the power flow problem for alternating-current (ac) and direct-current (dc) distribution networks by using a linear representation of the hyperbolic constraints i=p/v ↔ II∗ ...

    • Optimal Location of DGs in DC Power Grids Using a MINLP Model Implemented in GAMS 

      Montoya O.D.; Garrido Arévalo, Víctor Manuel; Grisales-Noreña L.F.; Gil-González W.; Garces A.; Ramos-Paja C.A. (Institute of Electrical and Electronics Engineers Inc., 2018)
      This paper addresses the problem of optimal location and sizing of distributed generators (DGs) in direct-current (dc) power grids by using a mixed-integer nonlinear programming (MINLP) formulation. The reduction of the ...

    • Power Flow Analysis in DC Grids: Two Alternative Numerical Methods 

      Montoya O.D.; Garrido Arévalo, Víctor Manuel; Gil-González, Walter; Grisales-Noreña L.F. (Institute of Electrical and Electronics Engineers Inc., 2019)
      This express brief proposes two new iterative approaches for solving the power flow problem in direct current networks as efficient alternatives to the classical Gauss-Seidel and Newton-Raphson methods. The first approach ...

    • Sequential quadratic programming models for solving the OPF problem in DC grids 

      Montoya O.D.; Gil-González W.; Garces A. (Elsevier Ltd, 2019)
      In this paper, we address the optimal power flow problem in dc grids (OPF-DC). Our approach is based on sequential quadratic programming which solves the problem associated with non-convexity of the model. We propose two ...
