Embodiment Construction

[0032] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0033] By adopting big data technology and comprehensive weighting method, the present invention collects indicators, screens the indicator system, standardizes, determines weights, calculates scores, etc., and constructs a power grid investment benefit assessment system for electric power enterprises, which will guide electric power enterprises to optimize investment in the future , Improving operating efficiency and benefits, it has great theoretical and practical significance. The process of this method is as follows: figure 1 As shown, the specific process is as follows.

[0034] 1. With benefit, investment increment and investment sum as the basic elements, construct an evaluation index system with a three-layer structure including target layer, criterion layer and index layer.

[0035] This step is based on the principles of combining...

Abstract

The invention relates to a power grid investment benefit evaluation method based on a comprehensive empowerment method, and belongs to the technical field of power enterprise benefit evaluation. The power grid investment benefit evaluation method comprises the following steps: firstly, utilizing big data technology to construct an evaluation index system of a multilayer structure, determining an evaluation object, and adopting a variable coefficient method, a correlation coefficient method and a main ingredient analysis method to screen indexes to obtain corresponding evaluation indexes; then, carrying out normalization processing to each evaluation index, and determining the weight of each evaluation index by utilizing the comprehensive empowerment method; and finally, establishing a comprehensive model, and obtaining an evaluation result of power investment benefit according to the weight of each evaluation index. The invention combines a subjective empowerment method and an objective empowerment method to carry out comprehensive empowerment to each evaluation index, a problem that the weights of each type of determined indexes in a traditional benefit evaluation process are affected by subjective assume or are changed along with the change of selected each-year data can be solved, and a decision information basis and a necessary decision management program can be provided for a power grid construction evaluator or decision maker.

Description

technical field [0001] The invention relates to a power grid investment benefit evaluation method based on a comprehensive weighting method, and belongs to the technical field of power enterprise benefit evaluation. Background technique [0002] In recent years, with the development of the power system and the deepening of reforms, the operation of power companies is facing increasing pressure. On the one hand, the unreasonable electricity price system has squeezed the profit margins of power grid companies; There is a serious shortage of funds, the grid financing capacity is insufficient, and the financing pressure is increasing. How to avoid low-efficiency and ineffective investment, scientifically arrange investment projects, reasonably grasp investment timing, pay attention to input-output benefits, effectively prevent and avoid operating risks, and steadily improve power grid economic benefits has become an urgent problem to be studied and solved. [0003] The current ...
