Distribution systems Reconfiguration using HSA in the presence of dispersed generation sources and shunt capacitors

Due to the numerous problems caused by losses and voltage drop in distribution networks, this issue should be resolved in any way possible. The most important proposed ways capacitor installation, installation of distributed generation (DG) sources and rearrangement in the network, each of which has valuable benefits. In this paper, in order to have the maximum advantages of these methods, in addition to performing optimal system Reconfiguration, (DG) sources and parallel capacitors are installed in the network to achieve the most efficient and least costly method possible. For this purpose, first a standard sample network such as IEEE 69-bus sample network is selected and simulated in MATLAB software environment. For the proposed method, three studies have been carried out that include: load flow in the base state of the sample network, determining the location and capacity of (DG) sources and parallel capacitors, and in the third step, simultaneous implementation of repositioning and system rearrangement in order to achieve the minimum losses in Network .The studied algorithm, harmony search and voltage profile curve of the sample network are also drawn and studied in each of the steps.
