The invention discloses a wind curtailment and large-scale electric heat storage coordinated operation method and belongs to the field of electric engineering. Based on the advantages of electric heatstorage, a hardware system is combined, and various data related to electric heat storage are monitored and recorded; and according to calculated important parameters, such as the environment temperature and the electric heat conversion efficiency, of an electric boiler, wind curtailment and large-scale electric heat storage coordinated operation parameter calculation functions are further constructed, therefore, the actual absorption effect of electric heat storage can be judged, and the related heat storage amount can be calculated. By means of the method, defects in the coordinated operation method field are made up; the purpose that wind curtailment is absorbed through electric heat storage is achieved, and the problem that the electricity is determined through heat is coordinated; and quite high practical performance and economical efficiency are achieved.
