Big power grid construction economical type assessment method

Abstract

The invention discloses a big power grid construction economical type assessment method, comprising steps of establishing an evaluation index system, calculating an index value according to the evaluation index system, wherein the evaluation index system comprises a peak shifting benefit, a mutual aid benefit, a backup benefit, a power supply benefit, an industry benefit, an environment benefit, an operation benefit, a production value benefit and a city benefit, choosing a folding line nondimensionalization mode to perform standardization processing on the evaluation indexes, adopting an addition integration method and a multiplication integration method to perform comprehensive empowerment on various standardized indexes, and establishing a comprehensive model to obtain a comprehensive scores, The invention can guide the electric power enterprise to establish investment benefit philosophy, promotes optimization design scheme and construction scale and is applicable to the big power grid construction economic evaluation research.

Description

technical field [0001] The invention relates to the technical field of electric power enterprise benefit evaluation, in particular to an economical evaluation method for large power grid construction. 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 grid investment...

AI Technical Summary

Problems solved by technology

[0003] The current grid investment economic evaluation methods are mostly limited to the feasibility study of a single grid construction project

Commonly used methods usually set the internal rate of return at an appropriate level, measure the expected electricity price increase, and then calculate the investment income based on the system electricity. There are large errors in the evaluation results, and the actual operation of the power grid is not used. The index cannot be comprehensive and true. Reflect the economic benefits of the power grid, and cannot analyze the factors that affect the economic benefits of power transmission and transformation projects
