2020-03-262020-03-262019IEEE Transactions on Circuits and Systems II: Express Briefs; Vol. 66, Núm. 11; pp. 1865-186915497747https://hdl.handle.net/20.500.12585/8917This 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 works with the set of nonlinear equations by rearranging them into a conventional fixed point form, generating a successive approximation methodology. The second approach is based on Taylors series expansion method by using a set of decoupling equations to linearize the problem around the desired operating point; these linearized equations are recursively solved until reach the solution of the power flow problem with minimum error. These two approaches are comparable to the classical Gauss-Seidel method and the classical Newton-Raphson method, respectively. Simulation results show that the proposed approaches have a better performance in terms of solution precision and computational requirements. All the simulations were conducted via MATLAB software by using its programming interface. © 2004-2012 IEEE.Recurso electrónicoapplication/pdfenghttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/article10.1109/TCSII.2019.2891640Direct-current power gridsIterative numerical methodsPower flow analysisSuccessive approximationsTaylor's series expansionElectric power transmission networksLinearizationMATLABNewton-Raphson methodNonlinear equationsNumerical methodsDirect current powerIterative numerical methodPower flow analysisSuccessive approximationsTaylor's series expansionElectric load flowinfo:eu-repo/semantics/restrictedAccessAtribución-NoComercial 4.0 InternacionalUniversidad Tecnológica de BolívarRepositorio UTB56919564100572081266355719149364855791991200
