The invention relates to a calculation method and device for wind curtailment electric quantity of wind power, computer equipment and a storage medium. The method comprises the steps of obtaining windpower curtailment electric quantities of different wind power curtailment electric quantity types, wherein the wind power curtailment electric quantity types comprise the reduction of reverse peak-load regulation wind-curtailment electric quantity, the reinforcement of positive peak-load regulation wind-curtailment electric quantity and the conversion of reverse peak-load regulation into positivepeak-load regulation wind-curtailment electric quantity; and according to the reduced reverse peak load regulation wind curtailment electric quantity, the reinforced positive peak load regulation wind curtailment electric quantity and the variable reverse peak load regulation wind curtailment electric quantity, the wind power wind curtailment electric quantity is obtained. By adopting the method,the wind power curtailment electric quantity can be classified, and different types of wind power curtailment air quantities obtained through calculation can be used as an important basis for evaluating the peak load regulation performance of the wind power curtailment participation system and making a peak load regulation compensation plan of the wind power curtailment participation system.
