GONZALEZ QUINTERO, José Angel; LISAN MESA, Ismael  y  HIFIKEPUNJE KANDJUNGULUME, Johannes. Heuristic Algorithm for Distribution Systems Reconfiguration By Means of Branches Exchange. Energética [online]. 2012, vol.33, n.3, pp. 196-204. ISSN 1815-5901.

The reconfiguration of the distribution net is also part of the operation of the electric systems of power. The problem of reconfiguration of the distribution net, well-known in the literature like DNRC (Distribution Network Reconfiguration), it is to find a structure of radial operation that minimizes the power system losses while satisfying the operation restrictions. This work presents a heuristic algorithm based on the simple branch exchange method. The advantage of this method resides in its easy understanding and its simplicity to always produce radial variants. Coming this way the delays of the radiality checkups that carry out other algorithms are avoided. The main disadvantage consists in that the obtained solution is a local optimum that not necessarily has to be the global optimum. A numeric example is used to explain the fundamental steps of the proposed methodology.

Palabras clave : DNRC; branch exchange; heuristic methods; optimization; losses; reconfiguration; distribution systems.
