Comprehensive Evaluation of Industrial Integrated Energy System Based on Grey Correlation Analysis and Entropy Weight Method
2023 IEEE/IAS INDUSTRIAL AND COMMERCIAL POWER SYSTEM ASIA, I&CPS ASIA(2023)
Abstract
The integrated energy system that couples conventional energy systems with emerging renewable energy systems has gradually become an important technical means to cope with global energy and environmental crises. Its essence of "on-demand energy supply and cascade utilization" can perfectly adapt to the energy consumption needs of industrial enterprises with "high energy consumption, high cost, and diverse types". In this study, an evaluation index system that covers economic, environmental, and technical aspects has been developed for the industrial integrated energy systems. Moreover, a comprehensive evaluation method based on grey correlation analysis and entropy weight method is proposed. According to the simulation results of a numerical study, the deep cascade utilization of waste heat and the introduction of renewable energy can both improve the comprehensive performance of the industrial integrated energy system.
