Bacterial Foraging Optimization for Dispersed Energy Resources Placement Considering Reliability Enhancement and Power Loss Reduction of Distribution Systems

Distributed generators are beneficial in reducing the losses effectively compared to other methods of loss reduction. On the other hand DGs can be implemented for improvement of reliability of system too. In this paper optimal DG sources placement using Bacterial Foraging Optimization (BFO) is discussed. The optimal size and location of the DG unit is calculated. Reliability and power loss reduction indices of distribution system nodes are modeled and with aiming to achieve to minimum power loss and the most reliability in a typical distribution system DG sizing and placement is addressed. The new idea of this paper is based on two subjects. At first, the issue of DG placement and sizing according to two various purposes including power loss reduction and reliability improvement as simultaneously is analyzed and disused. Another idea of this study is implantation of Bacterial Foraging Optimization (BFO) as optimization tool for this purpose. In the other word, this study at first has discussed the issue of DG sitting and sizing in distribution system based on both aims includes power loss reduction and reliability enhancement using Bacterial Foraging Optimization (BFO).
