Due to the high interconnection of the power system and natural gas system, recovery behaviors of the two systems would inevitably affect each other. It is essential to study a coordinated restoration strategy to enhance the resilience of the whole system in case of potential disruptions. In this paper, a novel restoration framework for interdependent gas and power systems (IGPSs) is proposed. Firstly, the restoration strategy optimization model with the objective of maximizing the resilience is constructed, in which the operating constraints of IGPSs are considered. Secondly, a reverse greedy method is proposed to efficiently solve the problem in a timely manner and the optimal restorative strategy can be obtained automatically. Finally, the effectiveness of the proposed method is validated by an IGPS test system.
