Problems solved by technology

The so-called cross-section distribution network refers to the various states of the distribution network itself at a certain point in time or within a very short time range (one year). Management factors are not included, and some economical evaluations are not applicable because what is being investigated is not a stage

Embodiment Construction

[0020] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] The intelligent distribution network comprehensive evaluation system and method of the present invention are specifically described as follows:

[0022] 1. Selection of smart distribution network indicators:

[0023] Table 1 Distribution network comprehensive evaluation index system

[0024]

[0025]

[0026] 2. Indicator weight

[0027] The weight refers to the importance between subordinate indicators with the same superior indicator, usually expressed as a percentage of the importance of the subordinate indicators, that is, the sum of the weights of the subordinate indicators with the same superior indicator should be 1.

[0028] Table 2 shows the weight relationship between the effect indicators; Table 3 shows the weight relationship between the secondary indicators in the characteristic category indic...

Abstract

The invention discloses a comprehensive evaluation system and a comprehensive evaluation method of a smart distribution grid. The system comprises a basic data input module, a scheme grading module, a scheme comparison module, a data input and output module, a database and an operating system, wherein the comprehensive evaluation system is based on the operating system; the basic data input module is used for inputting basic data formed by all microcosmic evaluation indexes into the system, the scheme grading module is used for newly building grading results and selecting criteria and weights to grade, the scheme comparison module is used for finishing the data comparison under the same criterion and weight and the data input and output module is used for respectively inputting and outputting scheme data, criterion data and weight data. Compared with the prior art, according to the comprehensive evaluation system, the criterion and weight can be adjusted according to the specific demands of different areas so as to perform evaluation which meets an actual condition, and references can be provided for the construction and transformation and near-optimal operation of the smart distribution grid.

Description

technical field [0001] The invention belongs to the technical field of distribution network, and in particular relates to a comprehensive evaluation system and method for distribution network. Background technique [0002] The distribution network is the intermediate link between the user and the power generation and transmission system, and is an important link to ensure the supply of high-quality and high-reliability electric energy to users. However, for a long time, under the influence of the idea of ​​"emphasizing transmission and neglecting transmission and not working", my country's urban distribution network has a shortage of investment funds, and there is still a big gap with foreign advanced distribution networks. The distribution network structure is unreasonable and the reliability of power supply Not high, large operating loss and other situations are common. With the rapid development of the economy and the continuous progress of the society, more and more atte...
