Optimum distribution network reconfiguration in presence DG unit using BBO algorithm

الملخص EN

The power electrical distribution network have a very weakly meshed reconfiguration, with loops between different source stations, but the operation is carried out via a tree-based reconfiguration.

This reconfiguration is determined by the closing and opening of switches device in objective to optimize the total real losses in consideration of the technical and topological distribution network constraints.

In this paper, a Biogeography Based Optimization (BBO) method based on graphs theory is proposed to search an optimal reconfiguration in presence of a distributed generation unit.

The proposed method is tested on different types of IEEE distribution networks (33bus, 69bus, 84bus) and validated on Algerian distribution network (116bus).

The proposed method was developed under MATLAB software.
