Day-ahead dispatching, hour-ahead dispatching and real-time dispatching are performed respectively in the invention; as the time scale narrows down, the prediction accuracy increases; sampling and feedback correction are performed continuously in real-time dispatching to ensure that the tie-line is in a section safety state and that the power grid runs safely.Begin hether it has 'hether it has hether it ha Next reached the 24h p reached the i reached the 1lOmin| cycNo cyNo athiNo cyl Yes Yes Yes Day-ahead Hour-ahead Real-time total loadtoalodtalod prediction prediction prediction Formulate a day- Formulate an hour-ahead Formulate areal-time ahead dispatching dispatching pre-output dispatching output pre-output strategy strategy strategy based on MPC rolling optimization Obtain the total day-ahead Obtain the total hour-ahead Obtain each real-time dispatching output figure dispatching output figure output figure Track each output to hour- Track each output to real- Feed back sampling and perform ahead dispatching time dispatching continuous correction until the end ofthe real-time dispatching cycle Figure 1 1/6
