Abstract :
In this paper, considering many advantages of distributed generation (DG) and also pay attention to the importance of optimum placement and sizing of these resources in order to reach its advantages, to determination of the optimal location and capacity of DG in distributed generation has been paid. unsuitable location and sizing of DG in distributed networks Leads to disadvantages including Increase losses, voltage profile destruction and reliability of network, stability reduce and harmonic increase. The optimizing that is noticed in this paper offered by presenting a sensitivity factor to reduce of annual energy loss in network and annual costs of DG. It used algorithm method in order to solve optimizing problem and also used IEEE 33-bus radial distributed network as system test. It used 288-h average load model and forward/backward sweep technique to calculate the annual energy loss.
