A resilience assessment of an interdependent multi-energy system with microgrids

ABSTRACT

Multi-energy systems (MES) depend on various energy sources to supply reliable and constant energy for our daily activities. The interdependencies between various energy sources could cause the MES to become vulnerable to unexpected failures. To enhance the resilience of a power distribution system against failures, incorporating microgrids has been deemed as one of the most effective strategies. Studies on the microgrid’s impact on the interdependent MES is thus far still limited. In this paper, the impact of adding microgrids on the resilience of an interdependent gas-power network is assessed. Graph and network theories are employed to model the interdependent gas-power network, and resilience assessments are performed to compare the effectiveness of different addition scenarios of microgrids to the network. The findings from this study will provide insights toward developing more advanced microgrid management systems as an approach to realize resilience in MES.
