It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
Example 1
As shown in fig. 1, in the embodiment of the present application, the present invention provides a networked control method for a high-frequency inverter power supply, where the method includes the steps of:
s1: acquiring historical demand power parameters of a load on a bus;

In the embodiment of the application, a historical demand power parameter of a load on a bus is obtained at first, wherein the historical demand power parameter is a historical demand power parameter of the load in a current previous preset time period; then obtaining a current output power parameter of the first high-frequency inverter power supply network, wherein the current output power parameter is the current output power parameter of the first high-frequency inverter power supply network at the current moment; then judging whether the current output power parameter is greater than the historical demand power parameter, if so, indicating that the current output power parameter provided by the first high-frequency inverter power supply network can completely bear the historical demand power parameter of the load on the bus, so that the current demand power parameter of the load on the bus can be borne with a higher probability; if the current output power parameter is smaller than the historical demand power parameter, the current output power parameter provided by the first high-frequency inverter power supply network cannot completely bear the historical demand power parameter of the load on the bus, therefore, the current required power parameter of the load on the bus can not be borne with a larger probability, so the number of the high-frequency inverter power supplies accessed into the first high-frequency inverter power supply network is calculated according to the historical required power parameter and the current output power parameter, and the calculated number of high-frequency inverter power supplies are accessed into the first high-frequency inverter power supply network to obtain a second high-frequency inverter power supply network, and all the loads are supplied with power through the second high-frequency inverter power supply network, therefore, the current output power parameter provided by the second high-frequency inverter power supply network can completely bear the historical required power parameter of the load on the bus.

s203: and taking the first historical instantaneous required power in the sequencing sequence as the historical required power parameter.
In an embodiment of the present application, the historical demanded power parameter may be a maximum historical instantaneous demanded power of a load on the bus. The maximum historical instantaneous demand power is the maximum instantaneous demand power of the load in the current previous preset time period, and when the current output power parameter of the first high-frequency inverter power supply network can bear the maximum historical instantaneous demand power, other lower instantaneous demand powers can also be borne with a higher probability.

The average required power is the average required power of the load in the current previous preset time period, and when the current output power parameter of the first high-frequency inverter power supply network can bear the average required power, other instantaneous required power can also be borne with a higher probability. Specifically, the historical instantaneous demand power of all the loads at each moment in a preset time period is obtained, then the sum of the demand power of all the historical instantaneous demand power in the preset time period is calculated, and then the average demand power of the demand power and the average demand power in the preset time period is calculated, so that the average demand power is the historical demand power parameter.
