Security Assessment of Interdependent Electricity-Gas Networks

Integrated energy networks are superb energy system configurations. There emerges many types of integrated energy networks, in which interdependent electricity-gas networks are commonly implemented ones. Security assessment the integrated energy network is a vital research topic, which is studied in this paper. First, the models of interdependent electricity-gas networks are shown with the coupling mechanism analyzed. Second, security assessment of the interdependent networks is implemented, in which the loss of load is selected as the indicator weighing security. Third, security assessment on the test electricity-gas networks is conducted. Simulation results demonstrate the effectiveness of the proposed security assessment strategy.
