Extreme typhoon weather poses significant challenges to the safe operation of integrated electricity-gas system (IEGS). Due to the increasingly close energy coupling relationship within IEGS
faults will further evolve after the initial disconnection of power lines caused by typhoon disasters. This paper proposes a distributed recovery strategy for the integrated electricity-gas system
in which the evolution of faults during typhoon disasters is taken into account. Firstly
the initial disconnection of power lines under the influence of typhoon stress is identified; meanwhile
the subsequent power line overload and electric pneumatic coupling faults are taken into consideration
and an IEGS fault evolution model under typhoon disasters is proposed. Secondly
based on the mutual benefits of various recovery resources and different energy flows
a recovery model for IEGS is constructed. Then
based on the boundary coupling relationship
IEGS is decoupled
and a scheduling control framework based on the consensus-based alternating direction method of multipliers is proposed to achieve decentralized implementation of resilience recovery strategies for each subsystem. Finally
the simulation results verify that the proposed method can be adopted to effectively deal with IEGS failures caused by typhoons
and only a small amount of boundary information interaction is required to implement resilience recovery strategies and restore the loss of load.
