Embodiment

[0068] see figure 1 , figure 1 It is a schematic flow chart of the school comprehensive energy efficiency evaluation method based on hierarchical coupling constraints in the embodiment of the present invention.

[0069] Such as figure 1 A school comprehensive energy efficiency evaluation method based on hierarchical coupling constraints, the method includes:

[0070] S11: Determine the three evaluation levels of the school's comprehensive energy efficiency evaluation system, user level, system level and equipment level, based on the standards of the energy-using system level;

[0071] Specifically, the first evaluation level is the user level, each energy user in the school energy system, such as teaching buildings, canteens, dormitories, etc.; the second evaluation level is the system level, the specific energy system within each user, such as central air-conditioning Energy systems, lighting systems, fire protection systems, etc.; the third evaluation level is the equipme...

Abstract

The invention discloses a school comprehensive energy efficiency evaluation method based on hierarchical coupling constraint, and the method comprises the steps: determining three evaluation levels ofa user layer, a system layer and an equipment layer of a school comprehensive energy efficiency evaluation system based on the standard of an energy consumption system level; based on the three evaluation levels and in combination with a coupling constraint algorithm, determining four evaluation indexes of a safety index, an economic index, an energy efficiency index and an environmental protection index of the school comprehensive energy efficiency evaluation system; substituting the actually measured data of the school into the three evaluation levels and the four types of evaluation indexes for calculation to obtain a school comprehensive energy efficiency evaluation result; and comparing and analyzing the school comprehensive energy efficiency evaluation result with main indexes of aschool comprehensive energy efficiency evaluation system to obtain the overall energy consumption level of the school. In the method of the invention, the school comprehensive energy efficiency evaluation method based on hierarchical coupling constraint can accurately and universally complete the task of evaluating the energy efficiency of comprehensive energy systems of different schools.

Description

technical field [0001] The invention relates to the technical field of electricity service, in particular to a school comprehensive energy efficiency evaluation method based on layered coupling constraints. Background technique [0002] Building a green society and forming a safe, low-carbon and environmentally friendly modern energy system are the main goals of the national energy reform. At present, there are mainly problems such as unreasonable ratio of various energy forms and high per capita unit energy consumption in energy use in cities. As a typical industry in society, schools have the characteristics of large-scale energy use, various forms of energy use, and strong regularity of energy use. They are suitable as the main industry components for the establishment of the overall energy efficiency model of society. At present, it is difficult to accurately and universally complete the task of energy efficiency evaluation of comprehensive energy systems in different s...
