Specifically, the percentage of the long-term contract output of each power unit in the first preset time extracted in step 2042 is used to calculate the total power mode power unit set at t0The total percentage of the medium and long term contract force at the time, for example: if the ith power unit is at t0The ratio of the medium-and long-term contract force at the moment is recorded as PL (i, t)0) Then the electric power unit is integrated at t0The total ratio of the time-based medium-long term contract force is
Step 2046, extracting the generated data of each power unit at the second preset time from the generated data of each power unit at the second preset time.

Further, the terminal comprehensively evaluates the output condition of each power unit in the full power mode according to the remaining power of the power system at a second preset time adjacent to the first preset time, for example: if the second preset time is recorded as t0At time +1, the ith power unit is set at t0The output value at +1 time is denoted as P (i, t)0+ 1); the terminal obtains a ratio value of the long-term contract output of each power unit at a second preset time from the output value of each power unit at the second preset time, for example: setting the ith electric power unit at t0The ratio of the medium-to-long term contract force at the time +1 is expressed as PL (i, t)0+1)。
Step 2048, determining a power generation subdata set of the power unit set at the second preset time according to the power generation subdata of each power unit at the second preset time; and taking the power generation sub-data set of the power unit set at the second preset time as a second power generation sub-data set.

And step 2050, determining the generating total difference value ratio according to the first generating data set and the second generating data set.
Specifically, the terminal calculates the total power generation difference value ratio of the power unit set at the first preset time and the second preset time according to the total ratio of the long-term contract output of each power unit extracted in step 2044 at the first preset time and the total ratio of the long-term contract output of each power unit extracted in step 2048 at the second preset time.
As an alternative embodiment, step 2050 includes:
step 20502, obtaining a total power generation difference value of the power unit set at the first preset time and the second preset time according to the output capacity of the power unit set at the first preset time and the output capacity of the power unit set at the second preset time.

In particular toGround, for example: if the power unit is integrated at t0The total ratio of the time-based medium-long term contract force is
At t0The total ratio of the medium-and long-term contract force at the +1 moment is
The electric power unit is integrated at t0And t0+1 Total difference between the medium and long term contract forces at two adjacent times is PLT (t)0+1)-PLT(t0)。
And 20504, obtaining the ratio of the total power generation difference value according to the total power generation difference value and the clearing capacity of the power unit set at the first preset time.

In one embodiment, step 206 includes:
step 2062, if the total power generation difference ratio is less than or equal to a preset threshold, determining the electric quantity fixed value of each electric power unit according to the fixed electric quantity ratio of each electric power unit.
Wherein, can set for according to the play clear demand in electric power market and preset the threshold value, this preset the threshold value and preferably 5%. Specifically, the ratio difference of the long-term contract output of the power unit set extracted in step 204 at the first preset time and the adjacent second preset time is compared with a preset threshold, whether the ratio difference is smaller than or equal to the preset threshold is judged, and if the ratio difference is smaller than or equal to the preset threshold, the ratio of the long-term contract output of each power unit is fixed to obtain an electric quantity fixed value of each power unit; if the occupation ratio difference value is larger than the preset threshold value, selecting a second preset time and a third preset time adjacent to the second preset time, obtaining the occupation ratio difference value of the long-term contract output of one or more electric power units at the second preset time and the adjacent third preset time, and continuously comparing the occupation ratio difference value with the preset condition.
For example, if the power units are grouped at t0And t0+1 Total Difference of Medium-and Long-term contract forces at two adjacent moments
Setting the preset threshold value to 5%, and judging delta PLT (t)0) Whether the content is less than or equal to 5 percent or not is met, if so, the meeting moment is marked as
The proportion of the long-term contract output in each power unit is fixed, and the fixed value of the electric quantity of each power unit is obtained and recorded as PLj(i)＝PL(i,t0) (ii) a If not, t is0+1 time replacement t0At the moment of time, i.e.

Specifically, for example: if the fixed value of the electric quantity of each electric power unit determined in step 2062 is PLj(i)＝PL(i,t0) The total fixed value of the electric quantity of the electric power unit set is
In this embodiment, the total power generation difference ratio of the power units at two adjacent moments is compared with a preset threshold, and the ratio portion of the long-term contract output in each power unit is fixed according to the comparison result, so that the ratio portion of the long-term contract output in each power unit can be prevented from being repeatedly fixed, and the accuracy and reliability of the fixed value of the electric quantity of each power unit are ensured.

For example, if tjThe proportion of long-term contract output in each power unit is fixed at the moment, tjThe residual capacity of the power system at the moment is P, and the fixed capacity value of each power unit is PLj(i)＝PL(i,t0) The total fixed value of the electric quantity of the electric power unit set is
According to formula Pj＝P-PLTjCalculating the clear power output of the electric power unit set, wherein PjThe clear power output for the power unit set.
