Abstract

Integrated energy system (IES) takes advantage of flexibility based on energy synthetic utilization, thereby considered as the future energy carrier with great potential. The energy hub (EH) is essential for multi-level energy exploitation and flexible conversion between electricity and other energy sources. It is hoped that this research will contribute to a deeper understanding of the impact of energy coupling on system reliability and help to map out future organizations. This paper presents a method for measuring reliability in IES based on the thought of impact increment and hierarchical decoupling optimization. It follows a case-study design to verify the efficiency of the hybrid methodology given before. Supported by the numerical results, the effects of energy synthetic utilization in terms of system reliability are evaluated and also analyzed at a power flow level.
