Comments on “A new heuristic approach for optimal reconfiguration in distribution systems” in 81 (2011) 282–289

Abstract

This short communication is a discussion of the paper entitled “A new heuristic approach for optimal reconfiguration in distribution systems” introduced a new approach for optimal reconfiguration of radial distribution systems. Besides, a load flow algorithm based on graph theory was presented in order to give precise branch currents, node voltages and system power losses. In the abstract and in the conclusion section of the above mentioned study, the author stated that the results show that the performance of the proposed method is better than that of several methods available in other published articles, and that the proposed technique represents an improved, more efficient method which can easily solve the distribution network reconfiguration problem compared with those other methods. However, this conclusion can not be deduced from the results given by the author because with the optimal radial configuration given for the test system used, the power losses obtained are higher than those obtained by some of the other methods. So, the proposed final solution is worse.
