This paper discusses the complex situation and characteristics of the new energy centralized control curve.In view of this phenomenon,this paper introduces the power-changed factor as well as the variable state marker variables and presents a complete set of strategy,which uses real-time dynamic closed-loop correction to eliminate the macro-data transition and microscopic data anomalies,to amend the power data.It not only guarantees the second-level refresh and data accuracy features required for big data presentations,but also takes into account the statistical demand that the statistical calculation of any time period must avoid the untrust worthy interval and the statistical loss.This strategy is also suitable for data corrections of other project cumulative quantity.
