Abstract: Aiming at the harmonic problem of the distributed generation (DG) connected with power distribution network, the capacity and installation of DG in power distribution network were studied. The DG penetration levels were calculated by artificial bee colony(ABC) algorithm in compliance with the limitation of harmonics in GB/T145491993. The impact of harmonic injection on power distribution network caused by capacity and installation of DG was analyzed; The limitations in compliance with the requirements of voltage regulation and harmonic distortion were determined; The DG penetration level was calculated complying with the limitation of harmonics by ABC algorithm. The results indicate that, the method for calculating DG penetration level can achieve the optimization goal, satisfy the constraint voltage adjustment and harmonic distortion limits, maximize access power distributed power, and provide the reference for the distributed power supply the best integrationpoint.

Key words: distributed generation（DG）; harmonic limitation; penetration level; artificial bee colony algorithm
