Garrido, "Voltage Stability Margin in DC Grids With CPLs: A Recursive Newton–Raphson Approximation," in IEEE Transactions on Circuits and Systems II: Express Briefs, vol. 67, no. 2, pp. 300-304, Feb. 2020, doi: 10.1109/TCSII.2019.2904211.https://hdl.handle.net/20.500.12585/9535This express brief addresses the voltage collapse problem in direct-current (dc) networks by using a recursive heuristic search algorithm based on the Newton-Raphson method. The determinant of the Jacobian matrix in the Newton-Raphson method is used as a sensitivity index to determine the maximum power consumption of the dc network. The recursive solution approach corresponds to a sequential power flow approach by incrementing all values of the power consumptions uniformly. Simulation results validate the efficiency of the proposed method in comparison to the large-scale nonlinear solvers available in the general algebraic modeling system optimization package. The MATLAB programming environment was employed for implementing the proposed recursive Newton-Raphson method.application/pdfenghttps://ieeexplore.ieee.org/document/8664198info:eu-repo/semantics/article10.1109/TCSII.2019.2904211Direct current networksNewton–Raphson power flowPure-algorithmic methodologySensitivity indexVoltage stability margininfo:eu-repo/semantics/closedAccessUniversidad Tecnológica de BolívarRepositorio Universidad Tecnológica de Bolívar
