Embodiment 1

[0028] The present invention utilizes the cluster analysis method to screen distribution network investment evaluation indicators, screens out indicators with a large degree of difference between the indicators and can properly reflect the distribution network investment efficiency, and performs DEA analysis with fewer but more precise indicators, thereby obtaining more accurate evaluations As a result, the specific process of the present invention will be described below using specific embodiments.

[0029] Please refer to figure 1 , a method for evaluating distribution network investment efficiency based on DEA analysis, including the following steps:

[0030] S1. Determine multiple decision-making units for the evaluation of distribution network investment efficiency;

[0031] S2. Select the input and output indicators of the distribution network investment efficiency evaluation decision-making unit;

[0032] S3. Utilize the cluster analysis method to classify and divide ...

Embodiment 2

[0041] Please refer to figure 1 , a method for evaluating distribution network investment efficiency based on DEA analysis, including the following steps:

[0042] S1. Determine multiple decision-making units for the evaluation of distribution network investment efficiency;

[0043] S2. Select the input and output indicators of the distribution network investment efficiency evaluation decision-making unit;

Abstract

A DEA analysis based distribution network investment efficiency evaluation method is provided. The method comprises the following steps: S1, determining multiple decision-making units for distributionnetwork investment efficiency evaluation; S2, selecting input indicators and output indicators of the decision-making units for the distribution network investment efficiency evaluation; S3, using the clustering analysis method to classify the input indicators and output indicators of the decision-making units, and obtaining multiple sets of screened input indicators and output indicators; and S4, using a data envelopment analysis and evaluation model to evaluate the multiple decision-making units, and obtaining the relative efficiency indices of the multiple decision-making units. The methodprovided by the present invention has the following advantages that: the clustering analysis method is used to screen the distribution network investment evaluation indicators, treasonable input indicators and output indicators are screened for the DEA analysis of the distribution network investment, and the indicators that have big differences between the indicators and can properly reflect distribution network investment efficiency can be screened, so that with less and better indicators to perform DEA analysis, more accurate evaluation results can be obtained.

Description

technical field [0001] The invention relates to the technical field of distribution network operation and management analysis, in particular to a method for evaluating distribution network investment efficiency based on DEA analysis. Background technique [0002] The distribution network has the characteristics of a large system, many points and a wide area, and a complex operating environment, and the distribution network directly connects power equipment and users, and is an effective connection and combination point for the integration of the two. Power grid investment is not only the expansion and renewal of hardware infrastructure, but also the innovation of management strategies, control models and social development. Therefore, when evaluating its investment benefits, it is necessary to consider the investment benefits of power grids from various aspects. Therefore, how to improve The investment efficiency of the distribution network is a very meaningful research work...
