The power supply unit division of the medium voltage distribution network considering the complementary of the load characteristics

The method of dividing the power supply unit considering the complementary of the load characteristic is presented to solve the problems of the large size of the network and low equipment utilization ratio caused by the lack of consideration of complementation of load characteristic in distribution network planning. First, based on the existing research results on load clustering and grid planning, the concepts of the feeder block and the power supply unit are redefined and the technical framework of MV distribution network planning considering the division of the power supply is designed. Then, the evaluation indexes of feeder block division considering the complementary of the load characteristic are set up, and rotation center line distance weighting alternate location algorithm is proposed to divide the feeder block. Further, the evaluation indexes of feeder block division considering complementary of the load characteristic are set up, and the method of dividing the power supply unit is proposed. Finally, the scientificalness and practicability of the model and method in this paper was verified through the case study.
