Abstract

The invention relates to a comprehensive energy system energy efficiency evaluation method and system based on energy efficiency improvement. The method comprises the steps that factors influencing system energy efficiency are divided into three aspects of economy, stability and environmental protection based on the actual operation condition of a comprehensive energy system; calculating the subjective weight of each index; calculating the objective weight of each index; comprehensively calculating the subjective weight and the objective weight to obtain a comprehensive weight value of each index, further calculating to obtain a comprehensive score of the system, and if the comprehensive score is higher than a preset threshold value, determining that the comprehensive energy efficiency level of the system is higher. According to the method, the energy efficiency level of a specific integrated energy system can be scientifically and reasonably evaluated; therefore, the method can be widely applied to the technical field of energy assessment.

Description

technical field [0001] The invention relates to the technical field of energy assessment, in particular to an energy efficiency assessment method and system for a comprehensive energy system based on energy efficiency improvement. Background technique [0002] In the context of energy reform, the coordinated design and operation of multiple energy sources to improve energy utilization is an important measure to ensure environmental security. The integrated energy system is an important embodiment of the Energy Internet, that is, in the process of planning, construction, operation, etc., after the orderly planning and optimization of energy production, transportation, distribution, storage and consumption, the energy production, Supply and consumption integration system. The development of an integrated energy system is the only way for the development of the new energy industry, an effective way to achieve energy conservation and environmental protection, and a research hot...
