摘要：
With the deepening of coupling degree between power grid and natural gas network, the interdependent characteristics between the two systems lead new problems about safe operation of system, which increases the risk of cascading failures in integrated electricity and natural gas system. Therefore, an analysis method of the impact of failure propagation for integrated electricity and natural gas system considering the interdependent characteristics between power grid and natural gas network is proposed. The interdependent characteristics of integrated electricity and natural gas network and the propagation mechanism of failures between the two networks are analyzed, based on this, the characteristics of failure propagation between the two networks under different coupling degrees of power grid and natural gas network are analyzed. Furthermore, the quasi-steady-state power flow equations of integrated electricity and natural gas system considering the slow time-scale dynamic characteristics of natural gas network are constructed. And then, from the perspective of energy supply efficiency and reliability of system, the impact of failure propagation on operation of integrated electricity and natural gas system is evaluated and analyzed by using the indicators of loss rate of load and loss rate of global network effectiveness, so that the assessment model of cascading failures of integrated electricity and natural gas system is constructed. © 2021, Electric Power Automation Equipment Press.
