Changed power information of the acquisition of information external loading in preset duration.Specifically, second controller 152 obtains the preset duration
The average value of interior multiple power informations, and the average value is stored.Second controller 152 obtains the average value of the preset duration
Difference between the average value of a upper preset duration for storage, the difference is the outside acquired in second controller 152
The changed power information being supported in the preset duration.
Second controller 152 can be based on N-Gram model algorithms and carry out deep learning.By N-Gram model algorithms,
Two controllers 152 the changed power information can be found according to changed power information corresponding to default change probability system
Number.Specifically, N-Gram models can be according to the changed power information searching of the preset duration in next preset duration, outside
The default change probability coefficent of section load changed power.For example, the changed power information of the preset duration is 500W, then according to N-
When Gram models find next preset duration, the power of external loading reduces 100W default change probability coefficent 0.5, subtracts
Small 200W default change probability coefficent 0.3, and increase 100W default change probability coefficent 0.2.Second controller 152 is to this
Default change probability coefficent corresponding to changed power information is randomly choosed, and then is obtained corresponding to the changed power information
Default change probability coefficent.
Second controller 152 is then prejudged outer according to the changed power information got and default change probability coefficent
Whether the changed power situation of section load increases.When judging the changed power situation of external loading in advance to increase, according to work(
Rate situation of change generation inversion control instructs the control terminal of the three-level inverter 141 into inversion output module 140, inverse to control
Become output module 140 before the changed power of external loading, in advance increase power output, so that inversion output module 140
Power output can match with the changed power of external loading in real time.When the changed power situation for judging external loading in advance is to subtract
Hour, then second controller 152 does not do control action, to ensure that the current power output of inversion output module 140 disclosure satisfy that
The current demand of external loading, and external loading demand power it is actual reduce when, then control to adjust inversion output module 140
Current power output is decreased to match with the power demand of external loading.
