Abstract

The invention belongs to the technical field of power grid comprehensive evaluation, and particularly relates to a power grid planning fuzzy comprehensive evaluation method based on comprehensive weighting, which comprises the following steps: S1, establishing a power grid planning index evaluation system suitable for electric power marketization reform; S2, determining the weight of each index inthe index system based on a comprehensive weighting method; and S3, collecting and processing each index data of the planning scheme to be evaluated, and establishing a power grid planning fuzzy comprehensive evaluation model. According to the method, subjectivity of expert weighting is considered, a comprehensive weighting method is used for processing judgment results of multiple experts, scientificity and practicability of index weight evaluation are improved, and a power grid planning scheme is comprehensively evaluated.

Description

technical field

[0001] The invention belongs to the field of power grid comprehensive evaluation, in particular to a fuzzy comprehensive evaluation method for power grid planning based on comprehensive weighting. Background technique

[0002] The existing power grid planning indicators do not take into account the changes in power grid requirements after the power market reform, mainly for certain aspects, such as the evaluation of the reliability of the power grid, low-carbon development, etc., and the expert weighting method is mainly used for weight determination , the results are too subjective, and the disagreement of expert opinions may affect the results of the comprehensive evaluation. Contents of the invention

[0003] In view of the above problems, the present invention proposes a fuzzy comprehensive evaluation method for power grid planning based on comprehensive weighting. The comprehensive weighting method is used in the weight determination to comprehensively...

Examples

Embodiment Construction

[0057] The embodiments will be described in detail below in conjunction with the accompanying drawings.

[0058] Such as figure 1 As shown, the specific steps of the fuzzy comprehensive evaluation method for power grid planning based on comprehensive weighting of the present invention are as follows:

[0059] S1. Establish a power grid planning index evaluation system that adapts to the power market reform. It also includes the following steps:

[0060] S1-1. According to the characteristics of the power market reform, select the three indicators of reliability, economy and environment;

[0061] According to the purpose of comprehensive evaluation of power grid planning, combined with the characteristics of the rapid development of new energy and the change of electricity price mechanism after the power market reform, the comprehensive evaluation of power grid planning is decomposed into three aspects: reliability, economy and environment, and these three aspects are screene...
