摘要：
Power system and natural gas networks can achieve high reliability operation through two-way coupling. In order to solve the recovery problem of electricity-gas integrated energy system after failure, a sequential fault restoration method is proposed. On the one hand, considering the two-way coupling characteristics of gas turbines and P2G(Power-to-Gas) equipment, the complementary mutual aid of the electricity-gas network is realized by scheduling the output of the gas turbine and P2G equipment during the reco-very process. On the other hand, considering the sequential characteristics of most devices in the recovery process, such as the capacity of energy storage battery, load consumption, wind turbine output and network topology change, a mixed integer programming model with multi-sequence for fault restoration is established, which is easily solved by piecewise linearization, and the optimal sequence of topology switch operations in the fault restoration process is obtained. Finally, the effectiveness of the proposed method is proved by the joint simulation of 13-bus power distribution network and 6-node gas distribution network. © 2019, Electric Power Automation Equipment Press.
