Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0071] Example 1

[0072] See also Figure 1 , the present invention provides a control method for a photovoltaic greenhouse energy storage system, comprising;

[0073] Step 1: Obtain all energy supply equipment that maintains the greenhouse environment in the agricultural planting site, classify each energy supply equipment into high-energy consumption equipment and low-energy consumption equipment based on its historical power consumption, and mark them as high-energy consumption equipment or low-energy consumption equipment respectively;

[0074] It should be noted that the agricultural planting site in step 1 can be represented by an area of a vegetable planting greenhouse or a fruit planting greenhouse, or similar environment that requires greenhouse maintenance, and all energy supply equipment for maintaining the greenhouse environment in the agricultural planting site is equipment that needs to maintain the greenhouse environment in the agricultural planting site for a long time.

[0075] The method for obtaining all the energy supply devices that maintain the greenhouse environment in the agricultural planting site, classifying them into high-energy-consuming devices and low-energy-consuming devices according to the historical power consumption of each energy supply device, and respectively marking them as high-energy-consuming devices or low-energy-consuming devices is as follows:

[0076] AS1: Among all the energy supply devices that maintain the greenhouse environment, each energy supply device is sequentially used as the target energy supply device to perform the following steps to determine whether it is a high-energy-consuming device or a low-energy-consuming device;

[0077] AS2: Then, obtain the historical power consumption of the target energy supply device every day in the previous n days;

[0078] Specifically, the calculation method of the historical power consumption per day is determined by multiplying the daily operating duration of the target energy supply device by the operating power of the target energy supply device;

[0079] It should be noted that the previous n days of the target energy supply device specifically refer to a time period starting from the current moment and pushing forward n days. In this embodiment, n = 30. The operating power of the target energy supply device can be determined according to the rated power of the target energy supply device, which is generally calibrated when the device is purchased and can be determined through the nameplate, instruction manual, and instrument measurement;

[0080] AS3: Compare the historical power consumption of the target energy supply device every day in the previous n days with the preset power consumption threshold respectively, and count the number of days when the historical power consumption of the target energy supply device in the previous n days is greater than the preset power consumption threshold, and mark it as G1. Calculate the ratio of G1 to n and compare it with the preset value h to determine whether the target energy supply device is a high-energy-consuming device or a low-energy-consuming device:

[0081] If then mark the target energy supply device as a high-energy-consuming device;

[0082] If then mark the target energy supply device as a low-energy-consuming device;

[0083] By obtaining the historical power consumption data of each energy supply device, the devices are accurately classified into high-energy-consuming and low-energy-consuming devices, providing a data basis for subsequent regulation; this can not only identify the devices with large energy consumption, facilitating targeted energy consumption management;

[0092] Sort the data in the set ECD from smallest to largest, and determine the first quartile Q1 of the set ECD through the following formula:

[0093]

[0094] Then determine the third quartile Q3 of the set ECD through the following formula:

[0095]

[0096] Obtain the first quartile Q1 and the third quartile Q3, determine the interquartile range IQR, IQR = Q3 - Q1;

[0097] BS5: According to the first quartile Q1, the third quartile Q3 and the interquartile range IQR, classify all energy supply devices into greenhouse impact level devices as follows:

[0098] If ECD i ≥ Q3 + 1.5 × IQR, classify this energy supply device as a first-level greenhouse impact device:

[0099] If Q1 + 0.5 × IQR ≤ ECD i < Q3 + 1.5 × IQR, classify this energy supply device as a second-level greenhouse impact device;

[0100] If ECD i < Q1 + 0.5 × IQR, classify this energy supply device as a third-level greenhouse impact device;

[0101] According to the key factors in the greenhouse environment (such as temperature, humidity, light, carbon dioxide concentration and water supply), quantitatively evaluate the impact degree of the equipment, and use the environmental coupling degree calculation to classify the equipment; so that the equipment with a greater impact on the greenhouse environment can be given priority attention, thereby better ensuring the balance and stability of the internal environment of the greenhouse, and further improving the scientific nature of the entire greenhouse management;

[0102] Step 3: According to Step 1, classify all energy supply devices into high-energy-consuming devices or low-energy-consuming devices, and according to Step 2, classify all energy supply devices into first-level greenhouse impact devices, second-level greenhouse impact devices, and third-level greenhouse impact devices. Overall, classify all energy supply devices into first-level greenhouse impact low-energy-consuming devices, first-level greenhouse impact high-energy-consuming devices, second-level greenhouse impact low-energy-consuming devices, second-level greenhouse impact high-energy-consuming devices, third-level greenhouse impact low-energy-consuming devices and third-level greenhouse impact high-energy-consuming devices;

[0103] Combine the results of Step 1 and Step 2 to achieve multi-dimensional grouping of energy supply devices (such as high / low energy-consuming devices with first-level greenhouse impact, second-level and third-level greenhouse impact devices); this refined grouping method enables differential energy supply according to the importance and energy consumption characteristics of the devices during subsequent energy regulation, so as to achieve the purpose of optimizing energy distribution and improving the overall regulation accuracy of the system;
