Resilient operation of multiple energy carrier microgrids

Abstract

This paper proposed a methodology to identify the vulnerable components, and ensure the resilient operation of coordinated electricity and natural gas infrastructures considering multiple disruptions within the microgrid. The micro-grid demands, which consist of electricity and heat demands, are served by the interdependent electricity and natural gas supplies. The proposed approach addressed the vulnerability of multiple energy carrier microgrids against various inter-dictions, which is used to apply preventive reinforcements to increase the resilience of energy supply and decrease the operation cost. The proposed methodology is formulated as a bi-level optimization problem to address the optimal and secure operation of multiple energy carrier microgrids. The interdependence between natural gas and electricity infrastructures is addressed to show the effectiveness of the presented methodology in improving the resilience of generation and demand scheduling against deliberate actions causing disruptions in the interdependent energy infrastructures in multiple energy carrier microgrids.
