Abstract

The invention relates to an active power distribution network planning method which comprises the following steps: (1) dividing power supply regions within a region covered by a planned active power distribution network, and determining a position of each transformer substation; (2) determining a complementary feature parameter Cij between any two transformer substations i and j according to a net load curve P(t) corresponding to each power supply region; (3) calculating a complementary feature distance Dij between any two transformer substations i and j according to the complementary feature parameter Cij between any two transformer substations i and j; (4) performing clustering analysis on the multiple transformer substations according to the complementary feature distance Dij between any two transformer substations i and j so as to determine A transformer substation groups operating in a jointed manner; (5) respectively determining an optimal wiring solution of a whole active power distribution network of each transformer substation group in the A transformer substation groups operating in the jointed manner at each moment of n moments t1, t2... and tn by adopting an intelligent algorithm. The active power distribution network planning method can fully excavate the adjustable complementary feature among the transformer substation under the active power distribution network, so that resources are effectively saved and the cost is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of distribution network planning, in particular to a distribution network planning method. Background technique [0002] In recent years, many new features have emerged in my country's distribution network. The proportion of distributed energy access including distributed power generation, energy storage and electric vehicles has increased year by year, and the distribution network has encountered problems such as large fluctuations and two-way power flows. my country's power distribution network generally adopts the "ring network design, open-loop operation" wiring method. Such a power distribution network has been difficult to meet the requirements of a large number of distributed power sources, intelligent controllable loads and energy storage equipment. Active distribution network is a major technical direction for the future development of distribution network firstly proposed by foreign countries. Thro...
