Problems solved by technology

[0002] With the rapid development of power loads in central cities, problems such as saturated substations, chaotic site layouts, and high load rates of equipment have appeared in central urban areas, resulting in the failure of my country's distribution network construction to meet the needs of power development.
Therefore, the traditional grid planning idea can no longer meet the development of modern urban distribution network, and the grid planning concept of distribution network has become an inevitable trend of distribution network planning in recent years.
[0003] However, in the existing technology, there are few studies on distribution network evaluation after distribution network grid planning. Lattice expansion multi-dimensional quantifiable comprehensive verification

Abstract

The invention discloses a grid distribution network planning evaluation method, which comprises the following steps: (S1) building an index system for a grid distribution network planning evaluation, wherein the index system is combination of a series of indexes selected for evaluating one parameter or a system operation state of distribution network planning; (S2) combining an analytic hierarchy process and a delphi method, and determining index weights of various indexes for the grid distribution network planning evaluation, wherein the index weights reflect the influence degrees of the indexes on the distribution network planning; (S3) determining index values and subordinate functions of the indexes for the grid distribution network planning evaluation and calculating evaluation scores of the indexes, wherein the subordinate functions are function relationships between the index values and evaluation criteria of the index values; and (S4) carrying out reverse deriving to obtain the evaluation score of the grid distribution network planning by the analytic hierarchy process according to the evaluation scores of the indexes. According to the grid distribution network planning evaluation method, safe and economic operation of the distribution network after grid planning can be ensured; and the practical situation of the grid distribution network planning can be comprehensively and accurately reflected.

Description

technical field [0001] The invention relates to a distribution network planning evaluation method, in particular to a distribution network planning evaluation method based on the concept of grid planning. Background technique [0002] With the rapid development of power loads in central cities, problems such as saturated substations, chaotic site layouts, and high equipment load rates have emerged in central urban areas, resulting in the failure of my country's distribution network construction to meet the needs of power development. Therefore, the traditional grid planning idea can no longer meet the development of modern urban distribution network, and the grid planning concept of distribution network has become an inevitable trend of distribution network planning in recent years. [0003] However, in the existing technology, there are few studies on distribution network evaluation after distribution network grid planning. Lattice expansion multi-dimensional quantifiable ...
