Özet:

 

Growing concerns over environmental impacts, improvement of the overall  network conditions, and rebate programs offered by governments have led to  an increase in the number of distributed generation (DG) units in commercial  and domestic electric power production. However, a large number of DG units  in a distribution system may sometimes contribute to high levels of harmonic  distortion, even though the emission levels of the individual DG units  comply with the harmonic standards. It is known that the nonoptimal size and  nonoptimal placement of DG units may lead to high power losses, bad voltage  profiles, and harmonic propagations. Therefore, this paper introduces a  sensitivity analysis to determine the optimal location of DG units, as well  as evolutionary programming and harmonic distribution load flow for  determining the optimal size of DG units in radial distribution systems. A  multiobjective function is created to minimize the total losses and average  total harmonic distortion voltage (THDv) of the distribution system.  The proposed methodology is tested with a 69-bus radial distribution system.  The proposed optimal placement and sizing of the DG units is found to be  robust and provides higher efficiency for the improvement of the voltage  profile and the minimization of the losses and THDv.
