A Fast Non-Decoupled Algorithm to Solve the Load Flow Problem in Meshed Distribution Networks

Abstract

The purpose of this work is to compare the classical methods of power flow resolution (Newton-Raphson and Gauss-Seidel) with a more recent algorithm known as Alternating Search Directions (ASD), for which its equations, the steps to follow, and the parameters to consider are described. In addition, a series of tests are performed in different distribution networks to detect whether it is more advantageous to use this algorithm or the classical methods, comparing the number of iterations, execution times, and the convergence behaviour achieved. Finally, the advantages of selecting certain parameters in the ASD algorithm is studied.
