Economic Adaptability Analysis of Typical Integrated Energy Systems

Abstract

The promotion of integrated energy systems is able to reduce pollutant emissions by using clean energy sources, to promote the replacement of traditional fossil energy with green electricity, and to improve human life quality. In order to popularize integrated energy systems, it is imperative to study its economic applicability. In this paper, according to the cold and thermal electricity load demand, energy prices, equipment technology, the optimization model of the energy system by using the nonlinear integer programming method is firstly established. Then the evaluation index values of different systems are obtained. Secondly, the entropy weight method and analytic hierarchy process (AHP) are applied to obtain the weights respectively. Finally multi-index evaluation model is set up by using the expert evaluation method to determine the important index weight. The simulation results based on the actual data in a certain place show that the evaluation results obtained by the subjective and objective weights are basically consistent, which verifies the accuracy and effectiveness of the proposed method for economic applicability of the typical integrated energy systems.
