Embodiment Construction

[0041] refer to figure 1 , the concrete process of the present invention comprises:

[0042] (1) Index determination and establishment of evaluation index system

[0043] Using the Delphi consulting method to determine the main factors affecting power grid planning, and classify these main factors, combined with the basic idea of ​​the analytic hierarchy process, to establish a comprehensive evaluation index system as shown in the attached figure 2 . attached figure 2 The hierarchical structure described above is established by decomposing and merging the objectives of the comprehensive evaluation of power grid planning layer by layer. and environmental coordination), the third layer is the indicator layer, which are the sub-indicators of the middle layer, and the specific relationship is shown in the attached figure 2 .

[0044] (2) Apply the AHP to determine the total weight of a single indicator

[0045] Table 1 shows the total weight coefficient of a single index....

Abstract

The invention develops an urban power grid program comprehensive assessment system based on a gray analytic hierarchy process. Firstly, the system utilizes Delphi expert consulting method to determine main factors which influence power network programming, and integrates basic ideas of the analytic hierarchy process to form a complete power grid program assessment index system comprising a plurality of hierarchies. Then an analytic hierarchy process is utilized to respectively calculate the weight of attributes of the end of the system. Secondly, a plurality of experts are selected to carry out marking on a power network program related to the weight of the attributes of the end of the system, and then the gray analytic hierarchy process is utilized to calculate the scores of the power network program given by the experts, and further weight coefficients of the selected experts are determined based on an entropy weight method. At last, comprehensive and integral scores of the power network program are obtained through utilizing a weighting method. The higher the comprehensive scores, the better the power network program is shown to be, that is to say, a programmed power network reaches a high level in terms of four aspects of adaptability, safety, economy, and environmental property.

Description

technical field [0001] The invention belongs to the technical field of power grid planning, and in particular relates to a comprehensive evaluation system for urban power grid planning based on the gray analytic hierarchy process. Background technique [0002] On the one hand, urban power grid planning is an important part of the overall urban development plan, and on the other hand, it is the basis for the renewal and transformation of urban power grids. With the large-scale development of urban power grid construction, there have been a series of problems that need to be solved urgently. The current grid planning evaluation methods mainly focus on the evaluation of grid adaptability, security and economical indicators, while ignoring the environmental factors of grid planning. Today, when the country vigorously advocates the harmonious and sustainable development of economy and society, environmental factors will receive more and more attention in power grid planning. ...
