And S102, determining the corresponding states of the energy storage units based on the residual capacity.

Wherein the state includes a full power state and a non-full power state.

For the embodiment of the application, after the residual electric quantity of each energy storage unit is obtained, the corresponding state of each energy storage unit is judged according to the residual electric quantity. The states include a fully charged state and a non-fully charged state. The state of each energy storage unit is determined, so that the energy storage units in the full power state are filtered, and the energy storage units in the non-full power state are reserved.

And S103, if the first energy storage unit in the non-full-charge state exists, calculating the capacity to be charged of the first energy storage unit based on the residual electric quantity and the preset total capacity.

For the present application examples. And after the first energy storage unit in the non-full-power state is determined. And calculating the capacity to be charged of the first energy storage unit according to the residual capacity of the first energy storage unit and the preset total capacity. The preset total capacity is the rated total capacity of the energy storage unit, and a worker can program the rated total capacity of the energy storage unit into the electronic equipment in advance, and can also set the preset total capacity through input equipment such as a keyboard and a mouse. Assume that the acquired remaining capacity is 100 ten thousand kW. The preset total capacity is 500 ten thousand kW. The capacity to be charged is obtained by calculation to be 400 ten thousand kW, namely the first energy storage unit is fully charged and needs 400 ten thousand kW of electric energy.

And S104, calculating the time required by full power of the first energy storage unit based on the generated power of the first power generation unit and the capacity to be charged.

The first power generation unit is a power generation unit corresponding to the first energy storage unit.

For the present application examples. The acquired power generation power of the first power generation unit is assumed to be 200 ten thousand kW/h. Taking step S103 as an example, the time required for full power is calculated to be 2 hours (h) according to the capacity to be charged of 400 kW and the generated power of 200 kW/h. I.e. it takes 2h for the first energy storing unit to be fully charged.

Therefore, the first energy storage unit is determined as a second energy storage unit, and the second energy storage unit still cannot reach a full power state after the rest power generation time is over. Therefore, it is necessary to determine a second power generation unit, and the second power generation unit generates power to the second energy storage unit to achieve the effects of supporting and accelerating charging, so that the second energy storage unit reaches a full power state after the remaining power generation time is over.

And if the second energy storage unit reaches a full power state after the rest power generation time is over, generating power according to the power generation power of 400 ten thousand kW/h.

And S1062, determining a power difference value based on the required generated power and the generated power of the generating unit corresponding to the second energy storage unit.

For the embodiment of the present application, taking step S104 and step S1061 as examples, the power generation power of the power generation unit corresponding to the second energy storage unit is 200 kW/h. And calculating according to the required power generation power of 400 ten thousand kW/h, wherein the obtained power difference value is 200 ten thousand kW/h. And continuously increasing the power generation power of 200 ten thousand kW/h to the second energy storage unit, so that the second energy storage unit can reach a full power state after the rest power generation time is over.

And S1063, judging whether a third power generation unit with the power generation power larger than the power difference exists.

And the third power generation unit is a power generation unit corresponding to the third energy storage unit in a full power state.

For the embodiment of the present application, the second power generation unit needs to be determined from the power generation unit corresponding to the third energy storage unit in the full power state. And according to the acquired generated power of each third power generation unit. And judging whether a third power generation unit corresponding to the power generation power larger than the power difference exists or not.

If so, the third power generation unit with the maximum generated power is determined as the second power generation unit S1064.

For the embodiment of the present application, the power difference value is taken as an example in step S1062, and it is assumed that the generated power of any third power generation unit is 250 ten thousand kW/h, that is, there is a third power generation unit with a generated power greater than the power difference value to supplement power generation to the second energy storage unit through the third power generation unit.

And S1065, if the power difference does not exist, determining at least two third power generation units of which the total power generation power is not less than the power difference as second power generation units.

For the embodiment of the present application, if the third energy storage unit does not exist, it is stated that the second energy storage unit cannot reach the full power state after the remaining power generation time is over only by one third power generation unit. For example, the power generation of the third power generation unit having the maximum power generation amount is 150 kW/h, and a predetermined effect cannot be obtained only by the third power generation unit. Assume that the power generation power of another third power generation unit is 100 ten thousand kW/h. And the second energy storage unit is supplemented with power generation through the two third power generation units. The total power generation power of the two third power generation units reaches 250 ten thousand kW/h and is more than 200 ten thousand kW/h of required power generation power. And if the sum of the generated power of the two third power generation units cannot meet the power difference, continuously adding the third power generation units which supplement the second energy storage unit for power generation until the sum of the generated power reaches the power difference. At least two third power generation units are thus determined, the sum of the starting powers of which is greater than the power difference, so that the second energy storage unit reaches the full state more quickly.

The working personnel are convenient for judging the durability condition of the energy storage unit according to the change of the historical charging time point.

And whether the energy storage unit has abnormal conditions can be judged according to the two change curves.

In other embodiments, for example, whether the actual capacity of the energy storage unit is decreased is determined according to the slope of the change curve at the charging time point and the slope included angle of the change curve of the discharging power. The steeper the slope of the average discharge power change curve is, the less obvious the change is, and the steeper the slope of the change curve at the charging time point is, the more violent the change is, the earlier and earlier the charging time point connected to the second power generation unit is, and then the too fast the power consumption speed of the energy storage unit is, the reduction of the actual capacity of the energy storage unit is.
