摘要：

The multi-energy flow system represented by the integrated energy system is the main measure to promote the transformation of low-carbon and energy-efficient energy. However, the security problems caused by the joint operation of multiple energy flow systems should not be ignored. In view of the static security problem of multi-energy flow system, this paper proposed the natural gas N-1 event as the contingency set and discussed the static security coupling analysis theory and method for multi-energy flow systems. First, the contingency set considering the breaking of the natural gas pipeline N-1 was proposed. And the breaking event was simulated by the Newton- Raphson algorithm. Then the standard matrix model was used to analyze the coupling mechanism of energy hubs in the process of fault cross-energy flow propagation. Finally, the state transition process was used to describe the dynamic characteristics of the natural gas pipeline networks in static security coupling analysis and evaluated the severity of the impact of a fault on the operational safety of the system and enable identification of critical events and fragile parts. The results of the example verify that the proposed theory and method are correct and effective. © 2019 Chin. Soc. for Elec. Eng.
