| Summary: | Typhoon disasters bring great challenges to the safe and stable operation of integrated electric-gas system (IEGS), which is increasingly occupied by new energy sources. Considering the lack of consideration of typhoon migration and wind power fluctuation in emergency dispatching research of IEGS during disasters, an IEGS emergency scheduling method considering the spatio-temporal characteristic of typhoon and severe wind power fluctuations is proposed in this paper. A spatio-temporal model of typhoon is established to quantify the time-varying fault characteristics of electricity-gas system components under the influence of wind and rain, and typical fault scenarios are screened by information entropy theory. Based on the timing-sequence migration of typhoon, IEGS double-layer emergency dispatching model in disaster is established. The upper power system side is the emergency robust dispatching model. The main problem is emergency dispatching for high-risk lines under the typhoon path, and the sub-problem optimizes the minimum load loss of the system under the most severe wind power fluctuations at the next moment. The lower natural gas system side provides the recovery support for the power side based on the information coupling interaction to optimize the operating state of the gas network under the disaster. The adaptive-alternating direction method of multipliers (AT-ADMM) algorithm is adopted to solve the model. An example is given to verify the effectiveness of the proposed method. |
