[0057] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0058] The actual measured active power operation data of a wind farm from 00:00 on January 1, 2010 to 24:00 on December 31, 2011 was selected from the Energy Management System (EMS) of Shandong Electric Power Dispatch and Communication Center. The sampling interval was 5 minutes, and the total Valid data is 210240. The load adopts the active power and reactive power data of the 110kV side outgoing line of the typical daily substation in this area, and the sampling interval is 5min. In order to obtain enough data samples for probabilistic feature extraction, the reactive power samples of the wind field and the root bus voltage samples should be reasonably calculated first. According to the actual ratio, taking the IEEE-39 node system as an example, analyze the node characteristics according to the above method.
[0059] Due to the advanced development of po...
