This paper describes the development of genetic algorithms for their application to the reconfiguration problem of radial distribution electrical networks, taking into account the expected occurrence of voltage sags. The reconfiguration is an optimization problem, which is formulated to obtain a radial topology representing the least voltage sags in certain buses. The electric system is represe...

Load flow is a very significant and essential tool for the analysis of any power system and is used in the operational as well as development stages. In this work, a modified load flow method is formulated for radial distribution systems. The topological characteristics of distribution systems are employed to make proposed load flow solution possible. The proposed method makes use of two matric...
