Embodiment

[0065] It is set to use the operating data of 14 prefecture-level companies in a certain province to test the distribution network investment effectiveness evaluation method based on fuzzy interval analytic hierarchy process. The data used in the test is based on the survey data of the distribution network status of the State Grid Corporation of China and the year-end summary statistical data. The statistical and calculation software is MATLAB.

[0066] 1. Import the basic index data, and standardize the data according to the fuzzy membership function. Among the indicators, indicators such as "comprehensive voltage pass rate", "N-1 pass rate of high-voltage distribution network", "connection rate of medium-voltage distribution lines" and other indicators are positive indicators, and formula (1) is used to calculate the degree of membership; Distribution transformer proportion", "medium-voltage heavy-duty line proportion", "comprehensive line loss rate below 10kV" and other ind...

Abstract

The invention provides a method for evaluating the investment effect of a power distribution network based on a fuzzy interval hierarchy analysis method. The method comprises the steps of A, establishing a power distribution network investment effect evaluation index system; B, subjecting indexes to dimensionless treatment by adopting the concept of a membership function in fuzzy mathematics, andestablishing an index grading standard; C, calculating the weight of each level of indexes by adopting a fuzzy interval algorithm; D, calculating the comprehensive score of the power grid by means ofa multiplying operator. According to the invention, the calculation result shows that the method can scientifically and comprehensively evaluate the investment effect of the construction project of the power distribution network. The method is good in engineering application prospect.

Description

technical field [0001] The invention belongs to the technical field of distribution network automation, and in particular relates to a distribution network investment effectiveness evaluation method based on fuzzy interval analytic hierarchy process (The Investment Benefit Evaluation Method of the Distribution Network Based on the Fuzzy Interval Analytic Hierarchy Process, FIAHP). Background technique [0002] In recent years, with the continuous deepening of power system reform, the pressure of global warming, smog and other environmental problems has been increasing, and the problems in power grid operation and planning have become more prominent. One of the important issues in power grid management and decision-making is to balance the contradictions between economic optimization, energy conservation and environmental protection, and system security. The specific manifestations are: on the one hand, the corporate attributes of power grid enterprises determine their charact...
