The solution of the original nonlinear quadratic model is achieved with this proposed formulation with minimal error when the dc network has a well defined operative conditions. The proposed approach provides an explicit solution of the power flow equations system, which avoids the use of iterative methods. Such a characteristic enables to provide accurate results with very short processing times when real operating scenarios of dc power grids are analyzed. Simulation results verify the precision and speed of the proposed method in comparison to classical numerical methods for both radial and mesh configurations. Those simulations were performed using C++ and MATLAB, which are programming environments commonly adopted to solve power flows. © 2018 Elsevier B.V.Recurso electrónicoapplication/pdfenghttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/article10.1016/j.epsr.2018.07.003Convex approximationLinear approximationLow-voltage dc power gridsNonlinear power flow equationsTaylor's series expansionC++ (programming language)Electric load flowIterative methodsMATLABNonlinear equationsNumerical methodsTaylor seriesConvex approximationLinear approximationsLow voltagesNonlinear power flowTaylor's series expansionElectric power transmission networksinfo:eu-repo/semantics/restrictedAccessAtribución-NoComercial 4.0 InternacionalUniversidad Tecnológica de BolívarRepositorio UTB5691956410055791991200572029964452283650240036449223500
