Quantitative evaluation method of energy saving and emission reduction benefits of power grid

Abstract

The invention discloses a quantitative evaluation method of energy saving and emission reduction benefits of a power grid. The quantitative evaluation method is characterized by comprising the following steps: S1, an index data preprocessing step, which comprises uniformization processing and dimensionless processing of data; S2, an index correlation processing step, which includes extracting a principal component of each system by the principal component analysis, after the first principal component is separated, obtaining a constituent coefficient of each second-level index to the first principal component, retaining the second-level indexes with the larger constituent coefficients, and deleting the second-level indexes with the smaller constituent coefficients; S3, an index weight determination step, which includes weighting according to the relative importance degree of the indexes and weighting according to the discrete degree of the index data; S4, an aggregate model construction step, which includes performing linear compensation among the evaluation indexes by adopting a linear weighted synthesis method and taking a linear weighting function of each index value as a comprehensive evaluation model; and S5, an evaluation result display step, which includes analyzing and displaying intermediate results and final results.

Description

technical field [0001] The invention relates to the field of power grid planning and operation, in particular to a quantitative evaluation method for power grid energy saving and emission reduction benefits. Background technique [0002] The indicators involved in the energy-saving and low-carbon development of the power grid cover a wide range and variety, require a large amount of data, and there may be correlations between indicators. The complex index system satisfies the comprehensive requirements of benefit evaluation, but makes it easy for decision makers to fall into the quagmire of a large amount of data, and cannot accurately and effectively grasp the development of power grid energy saving and low carbon benefits as a whole. Contents of the invention [0003] The purpose of the present invention is to provide a quantitative evaluation method for power grid energy saving and emission reduction benefits, which can help decision makers get rid of detailed analysis ...
