This paper presents an integrated electric-gas energy system fault recovery method based on bidirectional coupled devices. Simulation examples of an IEEE 13-node electric system and a 6-node natural gas system are used to validate the effectiveness of the method. YALMIP is used to model the simulations in the MATLAB environment, while CPLEX is used to solve the optimization issue. Three recovery strategies are compared under the system failure scenarios: independent failure recovery, failure recovery with GFT coupling only, and failure recovery taking into account both GFT and P2G coupling. The power and natural gas systems are bi-directionally coupled through one GFT and one P2G device. The outcomes demonstrate that the recovery strategy that incorporates the consideration of two-way coupled devices can greatly enhance the recovery of natural gas and electricity loads. Scenario 3\u2019 s total recovery is 41,488.12, which is 66.64% and 55.94% of Scenario 1 and Scenario 2\u2019 s respective recoveries. Through a detailed analysis of the changes in network topology and the output of energy conversion equipment during the recovery process, the resilience and effectiveness of the method presented in this study under various fault scenarios are confirmed.<\/p>\n\n\n\n
