The operation evaluation is essential to promote the economic and environmental performance of a community integrated energy system (CIES). Due to the abundant energy forms, flexible supply paths, and various conversion devices in CIES, the refined evaluation and analysis of the complex energy supply and consumption process in a CIES remain challenging. This paper develops a refined operation evaluation method for CIESs based on exergoeconomics. First, the exergoeconomic model of CIESs is established considering the energy supply and conversion relations. A refined evaluation index set is constructed on this basis, including energy efficiency, economy, and asset utilization level. The index quantification methods for energy storage and conversion devices are designed separately. Finally, the proposed method is implemented and validated in a practical CIES, which effectively identifies the potential for performance improvement and can be used in various applications such as comparative diagnosis of equipment status.
