Example two
Fig. 2 is a flowchart of a method for determining a gain of a power generation amount of a photovoltaic power generation station according to a second embodiment of the present invention, where the method is further refined on the basis of the foregoing embodiments, specifically, determining a target power generation amount gain of the target power generation station relative to the reference power generation station according to the target historical daily power generation amount, the target operational daily power generation amount, the reference historical daily power generation amount, and the reference operational daily power generation amount, and determining a historical daily power generation amount reference value according to the target historical daily power generation amount and the reference historical daily power generation amount; determining a reference value of the operation daily power generation amount according to the target operation daily power generation amount and the reference operation daily power generation amount; and determining a target power generation gain' of the target power generation station relative to the reference power generation station according to the historical daily power generation reference value and the operation daily power generation reference value so as to perfect a determination mechanism of the power generation gain. It should be noted that, in the embodiments of the present invention, parts not described in detail may refer to related expressions of other embodiments, which are not described herein.
As shown in fig. 2, the method includes:
s210, determining target historical solar power generation capacity and target operation solar power generation capacity of a target photovoltaic module matrix in a target power station, and determining reference historical solar power generation capacity and reference operation solar power generation capacity of a reference photovoltaic module matrix in a reference power station.

Wherein the historical daily power generation amount reference value is used for representing a difference in power generation amount between the target power generation station and the reference power generation station in the historical period.
Specifically, for each day in the history period, the ratio between the target daily power generation amount and the reference daily power generation amount of the day is determined, and then the ratios are added to obtain the average value, and the obtained average value is used as the reference value of the daily power generation amount. For example, the historical solar power generation amount reference value may be determined by a specific formula:
wherein f is a reference value of the historical daily power generation amount, n is the number of days in the historical period, g t1 Refers to the t-th in the history period 1 Target historical daily power production of day g t2 、…、g tn Analogize g to g c1 Refers to the c-th in the history period 1 Reference historical daily electrical production of the day g c2 、…、g cn And so on.
Illustratively, the current history period is preset to be three months, the daily history power generation amount reference value in the history period is calculated, the daily history power generation amount reference value is overlapped to obtain the three-month history power generation amount reference value, and the historical daily power generation amount reference value is obtained by determining the average value of the three month Shi Ri power generation amount reference values. Alternatively, the historical daily power generation amount reference value of each month in the historical period may be determined separately, and the historical daily power generation amount reference value may be determined by determining the average value of the historical power generation amount reference value of each month.

Specifically, the ratio between the target operation day power generation amount on the operation day and the reference operation day power generation amount is determined as the operation day power generation amount reference value. For example, the operation daily power generation amount reference value may be determined by a specific formula:
wherein g is a reference value of the power generation amount of the operation day, p is the current day of the operation day,for the target daytime power generation on the daytime of operation, < > day power generation on the daytime of operation>The reference day power generation amount on the day of the operation.
Illustratively, the preset history period is three months, and the first day after three months is the running day. Alternatively, the operation date may be a period of time after the operation date is the start of the operation date.
It can be appreciated that the present embodiment fully uses the advantages of the history data by determining the history daily power generation amount reference value and the operation daily power generation amount reference value, and increases the richness of the data.
S240, determining a target power generation gain of the target power generation station relative to the reference power generation station according to the historical daily power generation quantity reference value and the operation daily power generation quantity reference value.
Specifically, a difference between the operation daily power generation amount reference value and the history daily power generation amount reference value is determined, the power generation amount gain of the photovoltaic square matrix is determined by using the difference, and the target power generation amount gain of the target power generation station relative to the reference power generation station is determined based on the power generation amount gain of the photovoltaic square matrix.
Optionally, determining the target power generation gain of the target power generation station relative to the reference power generation station according to the historical daily power generation reference value and the operation daily power generation reference value comprises: determining a single square matrix generating capacity gain according to the historical daily generating capacity reference value and the operation daily generating capacity reference value; and determining the target generating capacity gain of the target power station relative to the reference power station according to the generating capacity gain of the single square matrix.
The single matrix generating capacity gain refers to generating capacity gain of a single matrix in a photovoltaic power station.
Specifically, the generating capacity gain of a single square matrix is determined according to the difference value of the historical daily generating capacity reference value and the operation daily generating capacity reference value, and the target generating capacity gain is obtained by the average value of the generating capacity gains of the square matrixes in pairs in the photovoltaic power station, wherein the two single square matrixes form a pair of square matrixes. For example, the target power generation amount gain may be determined by a specific formula:
wherein I is the generating capacity gain of the photovoltaic power station, g is the operating day generating capacity reference value, f is the history day generating capacity reference value, and a is the paired square matrix number.
