Comprehensive Benefit Analysis for Integrated Energy Systems Projects Based on AHP-fuzzy

Significant changes have been occurred to the energy supply and consumption mode of China. Nowadays, establishing integrated energy system has become the key method to build modern energy system with the characteristics of clean, low-carbon, safe and high efficiency. The research subject of this paper is to achieve the optimization and comparison of Integrated Energy Systems projects. The basic structure of Integrated Energy Systems was presented in the first place. Second, the comprehensive benefit evaluation indexes system was designed according to basic characteristics of Integrated Energy Systems projects. A comprehensive benefit evaluation model based on AHP-fuzzy theory was built and put into case study in the end. More importantly, the comprehensive benefit of different Integrated Energy Systems projects can be obtained to provide decision basis and reference to project optimization and selection.
