A Potential Function for the Power Flow in DC Microgrids: An Analysis of the Uniqueness and Existence of the Solution and Convergence of the Algorithms
(Springer New York LLC, 2019)The power flow equations in DC microgrids are nonlinear due to the presence of constant power terminals. In this context, a rigorous demonstration of the convergence and uniqueness of the solution for Newton’s method is ... -
Application of the backward/forward sweep method for solving the power flow problem in DC networks with radial structure
(Cartagena de Indias, 2020)This paper presents the application of the backward/forward sweep iterative method for solving the power flow problem in direct current networks with radial structure, considering resistive and constant power loads. The ... -
On the convergence of the power flow methods for DC networks with mesh and radial structures
(Cartagena de Indias, 2021-02)The convergence analysis of the power flow methodologies for direct current (dc) electrical networks is addressed in this paper. The Banach fixed-point theorem is employed to prove the convergence and uniqueness in the ... -
On the Existence of the Power Flow Solution in DC Grids With CPLs Through a Graph-Based Method
(Cartagena de Indias, 2020-08-27)This brief explores the formulation of the power flow problem in DC grids with a classical incidence matrix through a graph-based formulation. This corresponds to a compact representation of the conventional backward/forward ... -
Power Flow Analysis in DC Grids: Two Alternative Numerical Methods
(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 ... -
Power flow approximation for DC networks with constant power loads via logarithmic transform of voltage magnitudes
(Elsevier Ltd, 2019)This paper proposes a logarithmic transformation of voltages (LTVM) for the power flow in DC grids. This problem is non-linear due to the presence of constant power loads (CPLs), which also introduce a negative resistance ...
