Aiming at the problem of large load loss caused by ice disaster and other disasters in the integrated energy system with high proportion of renewable energy due to de-icing and emergency repair,an integrated energy system de-icing and emergency repair scheduling strategy considering emergency power supply vehicles is proposed.Firstly,according to the meteorological data,the physical characteristics of the icing growth process of transmission lines are analyzed,and the calculation expression of icing growth is established from the perspective of rime and rime icing.Secondly,the upper level optimization is to use the emergency repair team to quickly restore the power supply for the power grid during the ice disaster.The lower level optimization model is optimized for the integrated energy system and the emergency power supply vehicle,and the model is solved by the sperm whale algorithm.The IEEE 33 node is used to simulate the ice melting decision.The results show that the method based on this paper can improve the efficiency of the optimal scheduling of the integrated energy system and ensure the safe and stable operation of the power grid.
