Power user equipment evaluation method based on interval level analysis and interval entropy combination

Abstract

The invention discloses a power user equipment evaluation method based on interval level analysis and interval entropy combination. The power user equipment evaluation method comprises the following steps: step 1, constructing a level structure model according to a form of adopting interval indexes by power utilization user equipment, wherein the level structure model is established according to a target layer, a criterion layer and a scheme layer; step 2, comparing the interval indexes in the level model in pairs and constructing an interval judging matrix A; step 3, checking the consistency of the interval judging matrix A; if the consistency of the interval judging matrix A is more than 0.1, returning to the step 2; and repeating the steps until other steps are operated to obtain an index evaluation comprehensive interval weight w. According to the method, on one hand, aiming at that the evaluation of the power user equipment is lack of demand side response, a power user equipment evaluation index system is provided from three aspects of energy efficiency evaluation, security monitoring and demand response; and on the other hand, an interval level analysis and interval entropy combination method is adopted to make up for the deficiencies that the subjective randomness of a level analysis method and the objectiveness of an entropy method are too strong.

Description

technical field [0001] The invention relates to the field of electric power user equipment evaluation, in particular to an electric power user equipment evaluation method based on interval hierarchy analysis and interval entropy combination. Background technique [0002] With the development of smart grid construction, a large number of electric vehicles, distributed power sources, micro-grids, and smart homes (Smart Home) will be connected to the distribution network.

However, the subjective assignment method of the AHP can fully consider the user's subjective views on the indicators, but it is more arbitrary; the objective weighting method of the entropy weight method can start from the actual data analysis, and objectively mine the weight distribution of the indicators from the data , but cannot reflect the opinions of decision makers. At the same time, the above two types of methods are analytical methods of definite numbers, and cannot effectively deal with the uncertainty of pairwise comparison of indicators and the uncertainty of data accuracy in the calculation process of indicators. The present invention proposes A method for solving the evaluation index weight of power user equipment combined by interval analytic hierarchy process and interval entropy weight method
