Wind power consumption assessment method and device

The embodiment of the invention discloses a wind power consumption assessment method and device, which carries out assessment based on an electric power system including wind power and battery energystorage, wherein the battery energy storage can suppress the fluctuation of the wind power. The method comprises the steps of modifying a load curve under the condition that the combined output of thewind power and battery energy storage reaches the optimal, carrying out simulation analysis on a thermal power unit in the electric power system according to the modified load curve, and finally carrying out multi-dimensional assessment analysis on the wind power consumption from three aspects such as the stability, the reliability and the economy according to the optimized combined output of thewind power and battery energy storage and the simulation analysis of the thermal power unit, thereby enabling assessment for the wind power consumption to be more comprehensive, and improving the accuracy of wind power consump
