Power distribution network input and output evaluation system index simplification method

Abstract

The invention discloses an index simplification method for an input-output evaluation system of a distribution network, comprising the following steps: 1) establishing an input-output evaluation index system for a distribution network; 2) classifying the existing indexes according to the characteristics of the distribution network , and divide the entire index system into multiple levels; 3) calculate the weight of each index, determine the important index according to the weight, and delete the secondary index; 4) aim at the index system obtained after simplification in step (3) , to analyze the degree of correlation between each index, and to choose the index; 5) To assign weights to each index in the index system before and after the simplification, and to obtain the comprehensive evaluation scores of each city based on the actual data, and to compare and verify the rationality and quality of the index system after the simplification. effectiveness. In the process of establishing the index system, this method takes into account the simplification of the indicators and the correlation and importance of the indicators, avoids the redundancy among the indicators, improves the evaluation efficiency, and ensures the integrity and rationality of the information after the simplification of the indicators. and effective.

Description

technical field [0001] The invention relates to a distribution network data processing technology, in particular to an index simplification method for an input-output evaluation system of a distribution network. Background technique [0002] With the reform of the power system, the power market is becoming more and more mature, and the economic benefits of the power grid have attracted more and more people's attention. Through the comprehensive evaluation and analysis of the distribution network, a scientific and reasonable input-output evaluation index system and investment strategy model are established to realize precise investment and lean management of the distribution network and promote the sustainable development of enterprises and power grids. [0003] The basis of the distribution network input-output evaluation system is the establishment of evaluation indicators, and the construction of a scientific index system needs to consider many factors. When establishing ...

AI Technical Summary

Problems solved by technology

[0005] (1) The simplification of the index system is not considered, but the input-output index is constructed according to the physical laws of the power system, and the rationality of the index and the optimization of the index system are not studied in depth;

[0006] (2) The existing index simplification method does not consider the importance of the index and the correlation between the index at the same time, it is difficult to guarantee the independence of the simplified index and the integrity of the information
