Embodiment Construction

[0017] The technical solution of the invention will be described in detail below in conjunction with the accompanying drawings.

[0018] Aiming at the problem that the current power grid investment income evaluation model may exceed the node domain, and cannot calculate the index correlation degree and the lack of orientation of the index grade interval, the present invention proposes an accurate and effective evaluation of the benefits of power grid investment projects, and overcomes the The traditional evaluation model is a benefit evaluation method with the disadvantages of insufficient orientation and low information utilization rate. This method is as follows: figure 1 As shown, it mainly includes the following four steps.

[0019] 1) Select the evaluation index of power grid investment benefit to construct the evaluation index library, and divide the evaluation index into three types for index normalization processing

[0020] 11) Select and build an evaluation index li...

Abstract

The invention discloses a power grid investment benefit evaluation method based on an improved matter element extension model, and belongs to the technical field of power planning. According to the method, power grid investment benefit evaluation indexes are selected to construct an evaluation index library; the evaluation indexes are divided into three types to be subjected to index normalizationprocessing respectively; the method also has steps of carrying out weight assignment on indexes in the evaluation index library by adopting a combined weight method; establishing a classic domain ofa power grid investment evaluation index and a to-be-evaluated matter element by adopting a matter element extension model; constructing a corresponding matter element matrix, calculating the closeness between each index of the matter element to be evaluated and the evaluation index level, and finally determining the evaluation level to which the power grid investment project belongs. The power grid investment project evaluation method can accurately and effectively evaluate the benefit of the power grid investment project and overcome the defects that a traditional evaluation model is insufficient in directionality and low in information utilization rate, and the power grid investment project evaluation method can be used for evaluating the benefit of the power grid investment project accurately and effectively.

Description

technical field [0001] The invention discloses a network investment benefit evaluation method based on an improved matter-element extension model, and belongs to the technical field of electric power planning. Background technique [0002] Grid investment is an important part of grid annual planning and construction plan. In order to maximize investment benefits, it is necessary to accurately evaluate the benefits of grid investment. With the deepening and development of power system reform, it not only affects the investment scope, investment ability, investment demand and investment strategy of the power grid company, but also puts forward new requirements for the evaluation of the company's investment benefits. [0003] The current power grid benefit evaluation adopts the traditional matter-element extension model, and the evaluation level is determined according to the correlation degree, but this method has two shortcomings: 1) When an index value of the matter-element ...
