[0031] Example 1
[0032] See figure 1 As shown, for the annual time series load data given by the IEEE RTS79 system, the specific steps of the method of establishing a power system clustering load model are as follows:
[0033] 1) Enter the annual time series load data given by the IEEE RTS79 system;
[0034] 2) Arrange the annual time series load in step 1) in descending order to obtain the load duration curve;
[0035] 3) Divide the load duration curve in step 2) into 3 partitions, that is, the number of partitions n=3, and the first partition is the load between 0.8 and 1, which is the high contribution area; the second partition The load is between 0.5 and 0.8, which is a medium contribution area; the third partition is a load between 0.3 and 0.5, which is a low contribution area;
[0036] 4) The improved efficiency thresholds of the 3 partitions are respectively taken as: the improved efficiency threshold η of the high contribution area 1s =0.12, the improved efficiency thresho...
