Problems solved by technology

The characteristics and existing problems of the distribution network not only affect the construction of the distribution network, but also affect the investment benefits and investment decisions of investors
When evaluating the distribution network investment benefit, the distribution network investment benefit evaluation index constructed by the current research results is not clear about the characteristics of the distribution network, and it does not fully cover the investment benefit influencing factors with the characteristics of the distribution network.

Embodiment Construction

[0060] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings. The specific steps of a preferred embodiment of the distribution network investment decision-making analysis model based on the improved Topsis method of the present invention are:

[0061] S1. Comprehensively consider the internal and external benefit factors of distribution network investment, build a fishbone diagram model to identify factors affecting distribution network investment benefits, and build a distribution network investment benefit evaluation index system;

[0062] S2. Use the entropy weight method to determine the weight of the distribution network investment benefit evaluation index, and then select the combination of Euclidean closeness, Hamming closeness and gray relational degree to correct the original Euclidean distance, and strengthen the evaluation results, so as to construct an improved Topsis method. Distribu...

Abstract

A distribution network investment decision analysis model based on an improved Topsis method relates to the field of distribution network investment benefit. The distribution network connects the mainnetwork of the power grid with the electric power users, and undertakes the important task of supplying and distributing electric energy. With the growth of power demand, the scale of distribution network investment is increasing day by day, and the lack of research on distribution network investment benefit evaluation has become a short board affecting the overall development of the power grid.The invention summarizes the present situation and problems of distribution network investment, the factors influencing the investment benefit of distribution network are identified by fishbone diagram, construct the evaluation index system of investment benefit, Combined degree of closeness including hamming closeness, european closeness and grey relational degree is introduced to improve the simplicity of european distance of traditional topsis method, and to strengthen the evaluation results, which can help investors to evaluate the quality of samples more effectively, and provide more powerful theoretical support for the choice of distribution network schemes with similar investment benefits.

Description

technical field [0001] The invention relates to the technical field of distribution network investment benefit evaluation, in particular to distribution network investment decision analysis based on the improved Topsis method. Background technique [0002] The distribution network is an important link that connects power generation, transmission and transformation terminals and power consumption terminals, and distributes and provides power to power users. During the operation of the power grid system, the line loss of the distribution network accounts for more than 50% of the total loss of the power grid. The economy of the distribution network operation is one of the main problems faced by the distribution network construction. The investment benefit of the distribution network has become faster than the construction speed of the distribution network. Issues that deserve the attention of grid operators. The distribution network has the characteristics of small scale, less...
