Power transmission grid efficiency and benefit detection method based on Klee method and matter element extension model

Abstract

The invention provides a power transmission grid efficiency and benefit detection method based on a Klee method and a matter element extension model. The method comprises the steps of: 1) based on an established power transmission grid efficiency and benefit comprehensive estimating system, using the Klee method to carry out pairwise comparison on indexes of each level, obtaining an important degree sort, and finally obtaining the calculation weight of each index; 2) defining a reasonable operation range of each evaluation index, obtaining the distances of each index to different evaluation levels, and obtaining a proximity according to a shortest distance formula; 3) for each index, calculating the proximities of the index relative to the different evaluation levels, substituting the proximities into a level evaluation formula, obtaining a comprehensive evaluation value of a matter element to be evaluated, and giving the deviation degree of the evaluation level; and 4), for the same data and sort, utilizing a hierarchy analytical method to calculate a comprehensive evaluation result, comparing the comprehensive evaluation result with the comprehensive evaluation value obtained in the step 3), comparing the coincidence degrees with a practical development condition, further carrying out sensitivity analysis on the evaluation model with the higher coincidence degree, and obtaining index having the largest evaluation result influence.

Description

Technical field: [0001] The invention belongs to the field of power system optimization planning and operation efficiency benefit evaluation, and specifically relates to a transmission network efficiency benefit detection method based on the matter-element extension model of the ancient forest method. Background technique: [0002] The power grid is the carrier of power transmission and power market operations. To operate the power grid is to strengthen value creation and value guidance, to penetrate the awareness of benefits into all fields and links of power grid construction and operation, to give full play to the maximum power transmission and power trading functions of the power grid, and to maximize the input and output of the power grid. Conduct an in-depth analysis of the operating efficiency of the power grid, analyze the main reasons that affect the efficiency of the power grid, realize the safety of the power grid, maximize the benefits, guide the planning and con...

AI Technical Summary

Problems solved by technology

The uneven distribution of line load rate and the low utilization efficiency of individual lines are also obvious

The main reasons probably include three aspects: First, it is difficult to reasonably match the moderately advanced construction of the power grid with economic development and related project construction

Second, it is difficult to balance the fulfillment of social responsibilities and the improvement of power grid utilization

Third, due to the lack of necessary demand side management, the power grid needs to continuously meet the ever-expanding power supply requirements
