Determination the optimal number, location and size of Distributed Generation by using HBB-BC Modified Algorithm

Distributed generation is a good option for improving the voltage profile and reducing line losses, quality improvement, environmental pollutions and generally increasing the efficiency of energy production process. The appropriate location of distributed generation makes possible to achieve maximum benefits within them. However, if these productions are installed and operationalized in the wrong place, it may causes damage to the distribution network. Hence, the need for placement of distributed generation resources is the basic needs of using them. Various activities have been conducted regarding the placement of dispersed distributions with various objectives such as search techniques and or analytical methods in that all of which seek to reduce negative impacts and enhance applying the distributed generations in distribution networks. In this article, an initiative population based on the optimization method using the combination of CLONAG, PSO, BB-BC and GA algorithms have been suggested in which HBB-BC algorithm is revised in which an internal circle determines the location and size of DG and an external circle determines the number of optimized DG. Algorithm objective function has been considered as the improvement of voltage profile, losses reduction and costs has been implemented on 30 bus IEEE network the obtained results are reviewed.
