Abstract

The invention is suitable for the technical field of energy efficiency evaluation, and discloses an integrated energy system energy efficiency evaluation method and device, and terminal equipment. The comprehensive energy system energy efficiency evaluation method comprises the following steps: constructing a comprehensive energy system energy efficiency index system, and determining the evaluation index value of each evaluation index in the comprehensive energy system energy efficiency index system; evaluating each evaluation index through a plurality of evaluation models to obtain a weight value of each evaluation index and evaluation results corresponding to the plurality of evaluation models; combining the plurality of evaluation models, calculating a weight coefficient corresponding to each evaluation model in different model combination modes according to the weight value, and calculating evaluation results of the different model combination modes according to the evaluation index value and the weight coefficient; and calculating the correlation degree between the evaluation results of different model combination modes and the evaluation results corresponding to the plurality of evaluation models, and determining an optimal model combination mode and an optimal evaluation result according to the correlation degree.

Description

technical field [0001] The application belongs to the technical field of energy efficiency evaluation, and in particular relates to an energy efficiency evaluation method, device and terminal equipment of an integrated energy system. Background technique [0002] The integrated energy system is mainly composed of network, energy exchange link, energy storage and multiple end users. The integrated energy system integrates regional energy and optimizes the use, coordination, mutual response and complementarity of each energy subsystem. Energy efficiency assessment is an effective indicator to reflect the application level of energy efficiency. In a complex energy system, there are various types of energy input and output, which need to be evaluated from an overall perspective. The overall energy efficiency evaluation results for the integrated energy system are also called comprehensive energy efficiency. [0003] The evaluation method of comprehensive energy efficiency is a...
