Abstract

The invention discloses a grid investment benefit evaluation method based on multiple indexes and multiple levels. The grid investment benefit evaluation method is technically characterized by comprising the following steps of: constructing a grid investment benefit evaluation system comprising a main grid frame, a distribution network sub unit, a dividing specialty and a component voltage level investment benefit index; carrying out simplified processing on the index in the grid investment benefit evaluation system; carrying out unitization processing on the index in the grid investment benefit evaluation system; carrying out index weight calculation on the index in the grid investment benefit evaluation system; and evaluating the investment benefit of each examination object by using a linear comprehensive marking method. According to the method, the grid investment benefit evaluation system is constructed from four levels such as the main grid frame, the distribution network sub unit, the dividing specialty and the component voltage level investment benefit index; the accuracy of the investment evaluation is improved; the comparing and the finding of the problems existing in the grid investment are facilitated; and the grid investment benefit evaluation method can not only be used for post evaluation of the grid investment benefit or used for providing an important decision reference for the grid construction investment direction for the coming year.

Description

technical field [0001] The invention relates to a method for evaluating the investment benefit of a power grid enterprise, in particular to a method for optimizing and evaluating the investment benefit of a power grid based on multi-index and multi-level. Background technique [0002] Large-scale grid investment accelerates the technological innovation of grid hardware and software, ensures the stable and sustainable development of the power industry, and continuously develops new business growth points for grid companies, which promotes the growth of economic benefits of grid companies as a whole. It is of great significance to clarify the basic situation of power grid investment benefits and understand the comparison of power grid investment benefits in different regions and aspects, which is of great significance to the performance evaluation of power grid companies and investment decisions in the next stage. [0003] Power grid investment is not only the expansion and re...
