In order to meet the timeliness of emergency control in modern power grid and solve the control capacity allocation problem of the global method,an ultra-real-time emergency control strategy system based on individual machine energy function was proposed in this paper.Firstly,this paper proposed an emergency shutdown control strategy based on the individual machine energy function,which focuses on the severely disturbed critical machines,and proposed the calculation method of the control amount;Then,based on Attention Mechanism-long short term memory neural networks network,the disturbed trajectory of critical machines was predicted;Finally,this system judged the stability of the system according to the prediction curve combined with the individual machine equal area method,calculated the cutting capacity,and implemented the emergency control.This paper used the IEEE39 system to verify the effectiveness of cutting strategy and trajectory prediction method.
