Embodiment Construction

[0032] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0033] Such as Figure 1~2 As shown, the present invention proposes an active distribution network planning method, including the following steps:

[0034]1. According to traditional distribution network planning methods, such as the minimum load distance method, divide the power supply area within the coverage area of ​​the planned active distribution network and determine the location of each substation.

[0035] 2. According to the net load curve P(t) corresponding to each power supply area, determine the complementary characteristic parameter C between any two substations i and j ij , the specific process is:

[0036] Suppose the net load curves of any two substations i and j are P i (t) and P j (t), respectively in the net load curve P i (t) and P j (t) corresponding to take n time t 1 , t 2 ,...,t n , then the complementary characteristic parameter C b...

Abstract

The invention relates to a planning method of an active power distribution network. The planning method of the active power distribution network comprises the following steps: (1) dividing an active power distribution network coverage area into power supply areas, and determining the position of each transformer substation; (2) according to a net load curve P(t) corresponding to each power supply area, determining a complementary property parameter Cij between any two transformer substations i and j; (3) according to the complementary property parameter Cij between any two transformer substations i and j, calculating a complementary property distance Dij between any two transformer substations i and j; (4) according to the complementary property distance Dij between any two transformer substations i and j, carrying out clustering analysis on a plurality of transformer substations so as to determine A transformer substation groups which are subjected to combined operation; and (5) adopting an intelligent algorithm to independently determine an optimal wiring scheme for each transformer substation group in A transformer substation groups which are subjected to combined operation at each moment of n moments including t1, t2...tn, and determining the optimal wiring scheme of a whole active power distribution network. The planning method can fully dig adjustable complementary characteristics among the transformer substations under the active power distribution network and effectively saves resources and cost.

Description

technical field [0001] The invention relates to a distribution network planning method, in particular to an active 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. Through fl...
