The invention discloses a method for creating a grid flexible resource emergency response strategy based on a dynamic programming method, comprising the following steps of (1) obtaining a grid frequency difference to determine a grid operating state; (2) when a determined result indicates that the grid is in an emergency state, obtaining a power shortage amount and a schedulable flexible resourcecapacity to determine whether a frequency drop can be dealt with just by scheduling flexible resources including an energy storage device and a temperature control load; (3) if so, establishing a response model of the energy storage device and the temperature control load; (4) using the dynamic programming method to solve the flexible resource scheduling with the lowest electricity price based onthe power shortage amount, node electricity price prediction information, and the response model of the energy storage device and the temperature control load. The method alleviates the drop of the grid frequency by scheduling and optimizing social resources to the utmost extent, and solves the problem based on dynamic programming so as to increase a calculation speed.
