Embodiment Construction

[0063] The present invention will be further described below using the drawings and specific embodiments.

[0064] refer to figure 1 , a method for evaluating energy efficiency of electric power users of the present invention, comprising the steps of:

[0065] 1) Establishment of user energy efficiency index system

[0066] The construction of this index system comprehensively considers the user's electricity consumption habits, the characteristics of electrical appliances, and environmental factors, so that it can fully and accurately reflect the level of power energy efficiency. Combined with expert experience, a two-level evaluation index system was established. The first-level indicators include four types: user information, user power-saving equipment indicators, user common electrical equipment indicators, and environmental impact indicators. Index A mainly reflects user power energy efficiency from a subjective and macro perspective. The indicators B, C, and D mainly ...

Abstract

The invention discloses a power consumer power utilization energy efficiency evaluation method based on fuzzy comprehensive evaluation. According to the method, the power consumption energy efficiency of the user is evaluated by comprehensively considering the power consumption habits of the user, the use characteristics of electric appliances, environmental factors and the like. The method comprises the following steps: firstly, establishing a user power utilization energy efficiency index system, determining subjective weights and objective weights of indexes by adopting a method of combining an analytic hierarchy process and an entropy weight method, and obtaining comprehensive weights of the indexes through a calculation model; and secondly, according to the established index system, based on a fuzzy comprehensive evaluation method, evaluating the power utilization energy efficiency of the user, and on the basis of evaluation, carrying out grade division on an evaluation result. The result shows that the method for evaluating the power utilization energy efficiency of the user is a simple and practical energy efficiency evaluation method with high accuracy.

Description

technical field [0001] The invention relates to a method for evaluating energy efficiency of electricity consumption by users, and is a method for evaluating energy efficiency of electricity consumption comprehensively considering aspects such as user electricity consumption habits, electrical appliance use characteristics, and environmental factors. Background technique [0002] With the rapid development of my country's economy, the development problems of increasing energy consumption and low utilization rate have gradually become prominent. In order to alleviate the problem of energy shortage, energy conservation and emission reduction have become an urgent need. In recent years, the proportion of residential electricity consumption in the whole society's electricity consumption has been increasing year by year. Faced with the growing demand for electricity, most regions in my country have regional, seasonal, and uncertain power supply shortages. On the one hand, this i...
