Study On Method Of Comprehensive Energy Efficiency Evaluation For Distributed Energy System

Distributed energy systems are the focus of energy issues, and the existing energy system evaluation methods are mostly established for single-energy systems. Based on the characteristics of distributed energy system, a comprehensive energy efficiency evaluation system and method are presented for distributed energy system based on entropy weight method in this paper. It integrates economic indicators, energy efficiency technical indicators and environmental indicators. The traditional indicators have been filtered and the concept of construction cost growth coefficient is first put forward. The expert evaluation system and the purpose bias weight are added to the evaluation method at the same time. Finally, an example is given to compare the evaluation results of traditional system, PV system and gas turbine system under different evaluation.
