Abstract

Integrated energy system (IES) is an essential ingredient of energy reform. The construction of IES can promote the coupling utilization of multiple energy sources, and improve the reliability and flexibility of energy system. Based on amounts of literature study and experts’ recommendations, 9 first- class indexes, 13 second-class indexes and 11 third-class indexes are confirmed to assess the integrated energy system from three dimensions of technology, economy, and environmental protection. Analytic Hierarchy Process (AHP) and fuzzy comprehensive assessment method are adopted to assess the overall quality of chosen integrated energy system. An industrial park is chosen to be an example and examine the evaluation condition of IES.

Highlights

Integrated energy system (IES) is an important part of energy internet, and it’s the research hotspot in the field of energy, and the development direction of energy restricting

Summary

Introduction

Integrated energy system (IES) is an important part of energy internet, and it’s the research hotspot in the field of energy, and the development direction of energy restricting. Li et al [9] built universal flow system models from the aspects of energy distribution, conversation, and storage On this basis, the assessment system of IES from four dimensions of energy, devices, information, and system was come up. Zhang et al [11] established an index evaluation model of park-level integrated energy system for microgrid from the aspects of economy, reliability, energy consumption and environmental protection. The AHP-Delphi method can combine the data and practical experience to a certain degree, and obtain more objective and reasonable evaluation indexes of IES. This method is used to determine the indexes and weight, and a park will be tested by fuzzy comprehensive assessment method
