The invention provides a grouping method and system of orderly-power-utility peak-staggering stagger-stop users. The grouping method of the orderly-power-utility peak-staggering stagger-stop users comprises the steps of (1) obtaining historical load data of user metering points; (2) determining stagger-possible loads of the user metering points according to the historical load data; (3) determining circuit stagger-possible loads of circuits according to the stagger-possible loads of the user metering points; (4) carrying out grouping on the circuits of each power supply area according to the circuit stagger-possible loads, wherein the circuits of each power supply area are divided into N small peak-staggering groups, and small-group stagger-possible loads of the N small peak-staggering groups are consistent; (5) dividing N*P small peak-staggering groups into N large peak-staggering groups according to the small-group stagger-possible loads, wherein large-group stagger-possible loads of the N large peak-shifting groups are consistent, the N small peak-staggering groups of each power supply area are distributed into different large peak-staggering groups, the P is the number of the power supply areas, and the large-group stagger-possible load is equal to the sum of the small-group stagger-possible loads of the small peak-staggering groups in each corresponding large peak-staggering group. According to the grouping method and system of the orderly-power-utility peak-staggering stagger-stop users, accuracy and efficiency of grouping can be improved.
