In orde to solve the problem of insufficient powe supply capacity caused by the accuracy of new energy powe output, a new type of source-load-storage coordination unde the powe system is proposed. Dispatch method, using energy storage and flexible load voltage regulation capabilities to improve the trans­ mission capacity of the tie line unde emergency conditions, using energy storage centers and load aggregators to opti­ mize the equivalent load unde normal conditions, reducing the lack of powe supply capacity, and verifying the voltage unde emergency conditions through actual tests The co ectness of the regulation ability, through actual calculation examples to verify the co ectness of the im
