Chain Reaction Analysis of Integrated Energy System Considering Energy Hub Failures

As the development trend of future energy systems, the safe operation of integrated energy systems has always been the focus of research. The coupling degree of multi energy flow is increasingly deepening, and analyzing the impact of energy hub (EH) faults on the safe and stable operation of the system is of great significance. At the same time, the flexible adjustment ability of EH should also be considered. In response to the above issues, an integrated energy system chain reaction analysis method considering EH faults is proposed. Adjust the output based on the specific situation of EH faults and analyze the flow changes of each network. Finally, the effectiveness of the proposed method is verified using an industrial integrated energy system with a 6-bus power system and a 6-node thermal system as examples.
