[0078] During the data receiving or preprocessing stage, the collected power generation data and power consumption data are compared with the set threshold. If the data exceeds the preset maximum value, the data is identified as noise data. For the identified noise data, the data can be directly deleted or marked as invalid data, or interpolation, smoothing and other algorithms can be used to repair the missing or abnormal data.

[0093] Compare the power generation with the power consumption to get the power generation E f With the power consumption E u The size relationship of

[0094] When the power generation E f >The power consumption E u When the total active power P that needs to be reduced is controlled according to the power generation capacity of each generator set in the power generation unit, the corresponding active power is reduced; according to the power generation capacity of each generator set in the power generation unit, the total active power P that needs to be reduced is controlled according to the power generation capacity of each generator set in the power generation unit. zjx Using the following formula:

[0097] For example, Pifmin It can be 0, which means shutting down the corresponding generator set in the power generation unit.

[0098] When the power generation E f <The power consumption E u When the power generation capacity of each generator set in the power generation unit is controlled to increase the corresponding active power; the power generation capacity of each generator set in the power generation unit is controlled to reduce the corresponding active power, including:

[0099] Calculate the total active power P that needs to be reduced zjx , where P zjx =P f -P u ;

[0106] As shown in the figure, at this time, the irradiance is constant, and the active power is maximized under the same irradiance by adjusting the voltage;

[0107] Specifically, when I is at the minimum short-circuit current, P = 0;

[0108] As the voltage U increases and the current I remains unchanged, the active power P increases accordingly and can reach a maximum value at a certain point in time (see the time point in the figure). This time point is selected as Pifmax ;

[0109] Specifically, set the selection P ifmax Program. First, define an integer array arr, which contains the active power values ​​calculated under different voltages. Then, the program traverses the array through the getMax method to find the maximum power value; specifically, the getMax method initializes a maximum value as the first element of the array, and then compares each element in the array in turn. If an element is found to be larger than the current maximum value, the maximum value is updated. Finally, this method returns the maximum power value in the array. The program stores this maximum value in the variable number and uses this maximum value as P. ifmax The value of .

[0110] Then, as the voltage increases, the active power P will decrease until it is infinitely close to the open circuit voltage and the active power P is infinitely close to 0.
