Optimum Sizing and Siting for DG Unitsusing Hybrid 2/3 Rule and Harmony Search Algorithm

The electrical energy one of most important basics of modern lifeand the demand on this energy increase consciously. Which make some challenges to operators to increase the generation to feed the growing demand. This growth lead to extend the centralized plant to provide distribution network by required energy also lead them to develop transmission system. This method is so costly where it is required money to extend the power system. An appearance of distributed generation DG is considered a solution for these problems and can reduce the cost where it provides the load by electricity in customer side without passing through transmission system. While the aim target from DG is supporting the grid and improve power quality, voltage profile, reduction of power losses and reliability. In this paper will discuss sizing and siting the distributed generation in the grid.  In this work introduced hybrid method where it is used 2/3 rule and harmony search algorithm to find optimum location and sizing respectively. This work is done under several loading cases  up to 250 % from normal load also compared with other researches in this filed used the same model (IEEE 33 bus redial distribution system ) that used in this paper. MTLAB software used to complete this research.
