Power system splitting control method and device, and storage medium

The invention relates to the technical field of power system control, and discloses a power system splitting control method and device, and a storage medium, and the method comprises the steps: obtaining a volatile instability section of a power system through offline simulation, and enabling the volatile instability section to serve as a splitting scheme alternative library; acquiring a real-timestate of the power system through online simulation; predicting the transient stability of the power system according to the real-time state; judging whether the power system is unstable according toa prediction result; when the power system is unstable, obtaining an instability channel; selecting N easily-destabilized sections including the destabilized channel from the splitting scheme alternative library; wherein N is greater than 0, obtaining an optimal splitting section from the N easily-instable sections according to a preset economic indicator function, and performing splitting control on the optimal splitting
