Integrated Energy System Evaluation Method Based on Minimum Cross-Entropy and Prospect Theory

Abstract

An integrated energy system can improve the reliability and flexibility of the energy supply, and has good economic and environmental benefits. Integrated energy system evaluation is of great significance to the implementation of an integrated energy system project. The integrated energy system evaluation method is presented based on the minimum cross-entropy model and the prospect theory. Firstly, the minimum cross-entropy model is used to obtain the comprehensive column vector of each evaluation index. Secondly, the index weight is determined according to the different weight methods. Finally, through the establishment of positive and negative prospect value matrices, according to the comprehensive prospect value, the advantages and disadvantages of integrated energy system schemes are sorted. The effectiveness of the proposed method is verified by hotel-integrated energy system data.
