[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0034] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0035] The terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0036] In the description of the present application, it should be noted that unless otherwise clearly defined and limited, the terms "connected" and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations. In addition, when describing pipelines, the terms "connected" and "coupled" used in the present application have the meaning of conducting. The specific meaning needs to be understood in combination with the context.

[0037] In the embodiments of the present application, words such as "exemplary" or "for example" are used to represent examples, illustrations, or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0038] For the convenience of understanding, some basic concepts of terms or technologies involved in the embodiments of the present invention will be briefly introduced and explained first.

[0039] In the "Action Plan for Carbon Dioxide Peaking before 2030", it was proposed that "strengthen energy conservation and carbon reduction of new infrastructure, optimize the energy consumption structure of new infrastructure, increase the proportion of non-fossil energy consumption, adopt distributed energy storage, DC power supply, and the 'photovoltaic + energy storage' model, and explore diversified energy supply"; at the same time, the plan proposed to "accelerate the optimization of the building energy consumption structure, improve the electrification level of building terminals, and build a 'photovoltaic-storage-DC distribution-flexible power consumption' building integrating photovoltaic power generation, energy storage, DC power distribution, and flexible power consumption. By 2025, the renewable energy substitution rate of urban buildings will reach 8%, and the rooftop photovoltaic coverage rate of newly built public institution buildings and newly built factory buildings will strive to reach 50%", which points out the development goal for the "photovoltaic-storage-DC distribution-flexible power consumption" air conditioner.

[0040] Among them, the current output by the photovoltaic power generation device is direct current, which needs to be converted into alternating current synchronized with the power grid through an inverter and then connected to the building's internal power grid. The photovoltaic power generation device should be equipped with a storage battery, and the storage battery directly stores and releases direct current, which also requires the inverter to perform the conversion between alternating current and direct current during the storage and release process.

[0041] Regarding various electrical equipment in buildings currently, the lighting device uses an LED light source, which requires DC drive and needs to convert alternating current to direct current through a rectifier; for IT equipment such as computers and monitors, their internal is DC drive and also needs to first perform the voltage conversion and rectification from alternating current to direct current; for white goods such as air conditioners and refrigerators, the current development direction is to drive synchronous motors with frequency converters to achieve efficient and precise control of the motor speed. In this way, their internal also requires DC drive and needs to first perform AC / DC rectification; for high-power devices in buildings such as elevators, fans, and pumps, the current development direction of high-efficiency energy conservation is also variable frequency control with DC drive.

[0042] In this way, the development and technological progress direction of various building electrical devices are all changed from AC drive to DC drive. Photovoltaic and storage batteries also require DC access, and there are continuous conversions between alternating current and direct current in the building electrical system. Multiple conversions require repeated access to conversion devices, which not only increases equipment investment and the number of fault points, but also causes a conversion loss of nearly 10%. The power supply method of the traditional air conditioner system powered by a photovoltaic power generation device is energy-consuming and unstable.

[0043] Based on this, an embodiment of the present application provides an air-conditioning system, including: an air conditioner; a photovoltaic power generation device for generating electricity through light and supplying power to the air conditioner; a light prediction device for predicting the light intensity at a future moment; a light detection device for detecting the actual light intensity; a controller, configured to: obtain the predicted light intensity obtained by the light prediction device at a first moment for the light intensity at a second moment; determine the target energy storage mode of the air-conditioning system based on the predicted light intensity and the input power of the air conditioner under a stable operating state; control the air-conditioning system to store electricity based on the target energy storage mode; obtain the actual light intensity detected by the light detection device at the second moment; determine the target power supply mode of the air conditioner based on the predicted light intensity and the actual light intensity; and control the air-conditioning system to supply power to the air conditioner based on the target power supply mode.

[0044] In this way, the stability of powering the air conditioner through the photovoltaic power generation device is improved, and the energy consumption of the air conditioning system is reduced.

[0045] Based on this, the embodiment of the present application provides a hardware structure block diagram of an air conditioning system, such as Figure 1 As shown, the air conditioning system 1 may include a processor 2 and a memory 3 .

[0046] In some embodiments, the processor 2 and the memory 3 are electrically connected directly or indirectly to achieve data transmission or interaction. For example, these elements can be electrically connected to each other via one or more communication buses or signal lines.

[0047] In some embodiments, the air conditioning system 1 includes at least one software module that can be stored in the memory 3 in the form of software or firmware or fixed in the operating system (OS) of the cooking device 1 .

[0048] In some embodiments, the processor 2 is used to execute executable modules stored in the memory 3, for example, software function modules and computer programs included in the air-conditioning system 1, to implement a control method for the air-conditioning system.

[0049] In some embodiments, the processor 2 may execute a computer program after receiving an execution instruction. The processor 2 may be an integrated circuit chip having signal processing capabilities.

[0050] In some embodiments, the processor 2 can also be a general-purpose processor. For example, it can be a digital signal processor (DSP), an application specific integrated circuit (ASIC), discrete gate or transistor logic devices, or discrete hardware components, which can implement or execute the various methods, steps, and logic block diagrams disclosed in the embodiments of the present application. In addition, the general-purpose processor can be a microprocessor or any conventional processor, etc.

[0051] In some embodiments, the memory 3 can be, but is not limited to, a random access memory (RAM), a read only memory (ROM), a programmable read-only memory (PROM), an erasable programmable read-only memory (EPROM), and an electrically erasable programmable read-only memory (EEPROM).

[0052] In some embodiments, the memory 3 is used to store a program, and after receiving an execution instruction, the processor 2 executes the program.

[0053] In some embodiments, the memory 3 can be used to store software programs and data. The controller 1000 executes various functions and data processing of the air-conditioning system by running the software programs or data stored in the memory 3. The memory 3 can include a high-speed random access memory, and can also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage devices. The memory 3 stores an operating system that enables the air-conditioning system to operate. In the present application, the memory 3 can store the operating system and various application programs, and can also store the code for executing the control method of the air-conditioning system provided in the embodiments of the present application.

[0054] Figure 2 For another hardware structure block diagram of the air-conditioning system provided in the embodiments of the present application, as Figure 2 shown, the air-conditioning system 1 can also include a light detection device 4, a light prediction device 5, a photoelectric conversion device 6, an energy storage device 7, a photovoltaic power generation device 8, a scheduling device 9, an air conditioner 10, a signal transmission device 11, and a controller 1000 ( Figure 2 not shown in the figure).

[0055] In some embodiments, a light detection device 4 is configured to detect the actual light intensity at the current moment.

[0056] It should be noted that the light detection device 4 can be a possible detection device such as a light sensor, and the type of the light detection device 4 is not limited in this application.

[0057] In some embodiments, the light detection device can adopt the hot spot effect principle and use a detection component with a high response to weak light. These sensing elements are similar to the photosensitive matrix of a camera and have a wire-wound electroplated multi-junction thermopile inside, with a black coating with a high absorption rate on its surface. The hot junction is on the sensing surface, while the cold junction is located inside the body, and a thermoelectric potential is generated between the hot and cold junctions.

[0058] Furthermore, within the linear range, the output signal is proportional to the solar irradiance. The visible light passing through the filter irradiates the imported photodiode, and the photodiode converts it into an electrical signal according to the visible light intensity. Then the electrical signal enters the processor system of the sensor, thereby outputting the binary signal to be obtained, that is, the actual light intensity at the second moment can be measured.

[0059] In some embodiments, a light prediction device 5 is configured to predict the light intensity at a future moment (such as the second moment) to obtain the predicted light intensity at the future moment.

[0060] Specifically, the change in cloud conditions in the atmosphere is the main reason for the irregular change in light intensity. Therefore, when predicting the predicted light intensity at a future moment through the light prediction device 5, the weather information at the future moment can be obtained from the cloud or the server, so that the light prediction device 5 predicts the predicted light intensity at the future moment based on the weather information at the future moment.

[0061] Optionally, a light prediction model can be preset in the light prediction device 5, and the weather information at the future moment is input into the light prediction model for calculation to obtain the predicted light intensity at the future moment.

[0062] In some embodiments, the light prediction model can adopt intelligent algorithm prediction methods such as neural network models, genetic algorithm models, or support vector machines to predict the solar irradiance and light intensity data, and the light intensity data should be predicted separately according to different time periods of a day.

[0063] It should be noted that the light prediction method of the light prediction device 5 can also be other possible methods, which are not limited in this application.

[0064] In some embodiments, the light prediction device 5 can also predict the light radiation intensity at a future moment, and its prediction method is the same as the above light prediction method, which will not be elaborated here.

[0065] Further, the light intensity prediction device 5 may send the predicted light intensity and light radiation intensity to the photoelectric conversion device for output power conversion.

[0066] In some embodiments, the photoelectric conversion device 6 is configured to calculate the output power of converting the predicted light intensity into electric energy.

[0067] Specifically, when the light intensity prediction device predicts the predicted light intensity at the second moment, it sends the target light intensity to the photoelectric conversion device to convert the predicted light intensity into the output power of electric energy.

[0068] It should be noted that photoelectric conversion is a process of directly converting solar radiant energy into electric energy through the photovoltaic effect. The principle of this process is that photons transfer energy to electrons to make them move, thus forming an electric current.

[0069] In some embodiments, the photoelectric conversion device 6 is further configured to pre-store the output power of the air conditioner 10.

[0070] In some embodiments, the photoelectric conversion device 6 is further configured to obtain the light radiation intensity and the predicted light intensity at the second moment.

[0071] In some embodiments, the photoelectric conversion device 6 is further configured to perform data comparison of power, light radiation intensity, and predicted light intensity.

[0072] In some embodiments, the photoelectric conversion device 6 may be a photoconductive device (such as a photoresistor, a photodiode, a phototransistor), a photovoltaic device (a silicon photocell), or a semiconductor light-emitting device (such as a light-emitting diode, a light-emitting digital tube, an optocoupler). The present application does not limit the type of the photoelectric conversion device 6.

[0073] In some embodiments, the energy storage device 7 stores electric energy and supplies power to the air conditioner 10.

[0074] It should be noted that the energy storage device 7 may be an energy storage device, an energy storage battery, or other possible energy storage devices. The present application does not limit the type of the energy storage device.

[0075] In some embodiments, the photovoltaic power generation device 8 generates electricity through light and supplies power to the air conditioner 10.

[0076] In some embodiments, the photovoltaic power generation device consists of a photovoltaic module, a photovoltaic controller, an inverter, a storage battery, and other accessories (grid connection does not require a storage battery). The photovoltaic power generation device is divided into off-grid and grid-connected types according to whether it depends on the public power system.

[0077] Among them, the off-grid system operates independently and does not need to rely on the power system. The off-grid photovoltaic power generation device is equipped with an energy storage device 7 with energy storage function, which can ensure the stable power of the system and supply power to the air conditioner when the photovoltaic power generation device does not generate electricity at night or generates insufficient electricity on rainy days.

[0078] In some embodiments, the scheduling device 9 includes a power supply device 91 ( Figure 2 not shown in the figure) and a scheduling control module 92 ( Figure 2 not shown in the figure).

[0079] Among them, the power supply device 91 includes a first power supply device 911 ( Figure 2 not shown in the figure) and a second power supply device 912 ( Figure 2 not shown in the figure). The first power supply device is used to control the current switch between the power system and the energy storage device, and the second power supply device is used to control the current switch between the energy storage device and the air conditioner.

[0080] In some embodiments, the air conditioner 10 includes at least one air conditioner, and the number of air conditioners in the air conditioner 10 of the present application is not limited.

[0081] In some embodiments, the signal transmission device 11 is used to transmit signal information between various devices in the air conditioning system 1.

[0082] In the embodiments shown in the present application, the controller 1000 refers to a device that can generate operation control signals according to instruction operation codes and timing signals to instruct the air conditioning system 1 to execute control instructions. Exemplarily, the controller 1000 can be a central processing unit (CPU), a general-purpose processor network processor (NP), a digital signal processor (DSP), a microprocessor, a microcontroller, a programmable logic device (PLD), or any combination thereof. The controller 1000 can also be other devices with processing functions, such as circuits, devices, or software modules, and the embodiments of the present application do not impose any restrictions on this.

[0083] In addition, the controller 1000 can be used to control each component inside the air conditioning system 1 so that each component operates to achieve each predetermined function of the air conditioning system 1.

[0084] Figure 3 This is a block diagram of the hardware configuration of the air conditioning system provided by the present application according to an exemplary embodiment. As Figure 3 shown, the air conditioning system 1 may further include the following two items: a communication interface 1003.

[0085] In some embodiments, the communication interface 1003 is used to establish a communication connection with other network entities, such as establishing a communication connection with a terminal device. The communication interface 1003 may include a radio frequency (RF) module, a cellular module, a wireless fidelity (WIFI) module, a GPS module, and the like. Taking the RF module as an example, the RF module can be used for signal reception and transmission. In particular, the received information is sent to the controller 1000 for processing; in addition, the signal generated by the controller 1000 is sent out. Usually, the RF circuit may include, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier (LNA), a duplexer, and the like.

[0086] Those skilled in the art can understand that Figure 3 the hardware structure shown in does not constitute a limitation on this air conditioning system. The air conditioning system may include more or fewer components than shown in the figure, or combine certain components, or have different component arrangements.

[0087] Figure 4 is an internal interaction diagram of an air conditioning system provided by an embodiment of the present application. As Figure 4 shown, the kinetic energy device of the air conditioner 10 includes an AC-DC module 1, a DC-AC module, and a compressor M. The electric energy generated by the photovoltaic power generation device 8 can be directly supplied to the air conditioner 10 for use, or the electric energy can be stored in the energy storage device 7.

[0088] In some embodiments, the energy storage device 7 can also purchase electricity from the power system for storage.

[0089] In some embodiments, the light detection device 4 and the light prediction device 5 obtain the actual light intensity, the actual light radiation intensity, the predicted light intensity, and the predicted light radiation intensity according to the radiation intensity and light intensity of the sun.

[0090] Further, the photovoltaic conversion device 6 can calculate the output power of converting the predicted light intensity into electric energy through the obtained predicted light intensity and predicted light radiation intensity, and transmit the output power of converting the actual light intensity, the actual light radiation intensity, and the predicted light intensity into electric energy to the scheduling device 9 through the signal transmission device 11. The scheduling control module 92 selects the target energy storage method and the target power supply method of the air conditioning system according to the actual light intensity, the actual light radiation intensity, and the output power of converting the predicted light intensity into electric energy.

[0091] In some embodiments, the AC-DC module 1 and the AC-DC module 2 are used to convert alternating current into direct current.

[0092] In some embodiments, a DC-AC module is configured to convert the DC power supply of the power system into an AC power supply with stable output voltage and frequency.

[0093] Figure 5 The flowchart of a control method for an air-conditioning system provided by an embodiment of the present application is shown in Figure 5 As shown, the method includes the following steps:

[0094] S101. The controller obtains the predicted light intensity at the second moment.

[0095] Optionally, the controller can predict the light intensity at the second moment at the first moment through a light prediction device to obtain the predicted light intensity.

[0096] Wherein, the first moment is before the second moment.

[0097] Exemplarily, the first moment can be 8:00, 10:00, 12:00, 14:00, etc. today, and the second moment can be 8:00, 10:00, 12:00, 14:00, etc. the next day.

[0098] Specifically, the controller can obtain the predicted light intensity at 8:00 the next day through the light prediction device at 8:00 today, and can obtain the predicted light intensity at 14:00 the next day through the light prediction device at 12:00 today.

[0099] In some embodiments, since there is a correlation between the light intensity and the power generation amount of the photovoltaic power generation device, the predicted power generation amount at the second moment can be predicted by obtaining the predicted light intensity at the second moment, so as to predict whether the predicted power generation amount can meet the stable operation of the air conditioner.

[0100] S102. The controller determines the target energy storage mode of the air-conditioning system according to the predicted light intensity and the input power of the air conditioner in a stable operation state.

[0101] In some embodiments, the controller can determine the target energy storage mode of the air-conditioning system according to the predicted light intensity. Figure 6 The flowchart of another control method for an air-conditioning system provided by an embodiment of the present application is used for the target energy storage mode of the air-conditioning system, as shown in Figure 6 As shown, the method includes the following steps:

[0102] S201. The controller obtains the output power of the photovoltaic power generation device that converts the predicted light intensity into electric energy.

[0103] Optionally, the controller can obtain the output power of the photovoltaic power generation device that converts the predicted light intensity into electric energy through a photoelectric conversion device.

[0104] In some embodiments, after the controller obtains the predicted light intensity at the second moment through the light prediction device, the predicted light intensity is input into the photovoltaic conversion device, and the output power of the photovoltaic power generation device converting the predicted light intensity into electric energy is calculated.

[0105] In some embodiments, the stable operation state of the air conditioner is used to indicate that the input power of the air conditioner under the current stored power of the air conditioning system can meet the user's demand for temperature adjustment of the air conditioner.

[0106] It should be noted that the input power of the air conditioner in the stable operation state is set by the air conditioning system manufacturer and stored in the memory. The input power of the air conditioner in the stable operation state includes rated power and maximum power data. Different air conditioning system manufacturers set different input powers of the air conditioner in the stable operation state, and this application does not limit this.

[0107] S202. The controller determines the target energy storage mode of the air conditioning system according to the output power and the input power.

[0108] Among them, the target energy storage modes include buying electricity from the power system and storing it in the energy storage device and not storing energy.

[0109] In some embodiments, after the controller determines the output power of converting the predicted light intensity into electric energy by the photovoltaic power generation device and the input power of the air conditioner in the stable operation state, the target energy storage mode of the air conditioning system can be determined according to the output power and the input power. Figure 7 It is a schematic flowchart of another control method for an air conditioning system provided by an embodiment of the present application, used for the target energy storage mode of the air conditioning system, as Figure 7 shown. The method includes the following steps:

[0110] S301. When the output power is less than or equal to the product of the input power and the power correction coefficient, the controller determines that the target energy storage mode of the air conditioning system is to buy electricity from the power system and store it in the energy storage device.

[0111] It should be noted that the power correction coefficient is used to make up for the situation where the light radiation intensity and the predicted light intensity are on the high side. Its value is associated and matched with the accuracy of the light prediction model, and its value can be gradually corrected according to the operation of the whole set of equipment.

[0112] Optionally, the power correction coefficient can be α.

[0113] In some embodiments, when the output power of the photovoltaic power generation device converting the predicted light intensity into electric energy is less than or equal to the product of the input power and the power correction coefficient, the electric energy generated by light power generation cannot meet the input power of the stable operation of the air conditioner. Therefore, it is not possible to rely solely on the photovoltaic power generation device for power generation, and it is necessary to buy electricity from the power system in advance and store it in the energy storage device for use by the air conditioner.

[0114] In some embodiments, there is a correlation between the output power of the photovoltaic power generation device that converts the predicted light intensity into electrical energy and the predicted light radiation intensity. The calculation method of the output power of the predicted light intensity converted into electrical energy is shown in formula (1):

[0115] P1 = S * R * a Formula (1)

[0116] Wherein, P1 is the output power of the photovoltaic power generation device that converts the predicted light intensity into electrical energy, S is the area of the photovoltaic power generation device, R is the predicted light radiation intensity, and a is the photoelectric conversion rate.

[0117] Furthermore, when the output power P1 is less than or equal to the product of the input power P2 and the power correction coefficient α, that is, when P1 ≤ αP2, it is determined that the target energy storage method of the air-conditioning system is to purchase electricity from the power system and store it in the energy storage device.

[0118] S302. When the output power is greater than the product of the input power and the power correction coefficient, determine that the target energy storage method of the air-conditioning system is no energy storage.

[0119] In some embodiments, when the output power of the photovoltaic power generation device that converts the predicted light intensity into electrical energy is greater than the product of the input power and the power correction coefficient, the electricity generated by light can meet the input power for the stable operation of the air conditioner, so there is no need to purchase electricity from the power system in advance and store it in the energy storage device.

[0120] Exemplarily, when the ratio between the output power P1 and the input power P2 is less than or equal to the power correction coefficient α, that is, when P1 > αP2, it is determined that the target energy storage method of the air-conditioning system is no energy storage.

[0121] S103. The controller controls the air-conditioning system to store electricity based on the target energy storage method.

[0122] In some embodiments, after the target energy storage method of the air-conditioning system is determined, the controller controls the air-conditioning system to store electricity based on the target energy storage method.

[0123] Exemplarily, when the controller determines that the target energy storage method of the air-conditioning system is to purchase electricity from the power system and store it in the energy storage device, the controller controls the dispatching device to turn on the switch from the power system to the energy storage device, and store electricity from the power system in the energy storage device.

[0124] Exemplarily, when the controller determines that the target energy storage method of the air-conditioning system is no energy storage, the air-conditioning system does not store electrical energy at night, and directly supplies power to the air conditioner by the photovoltaic power generation device the next day, and stores the surplus electricity in the energy storage device.

[0125] S104. The controller obtains the actual light intensity at the second moment.

[0126] Optionally, the controller can detect and obtain the actual light intensity through the light detection device at the second moment.

[0127] S105. The controller determines the target power supply mode of the air conditioner according to the predicted light intensity and the actual light intensity.

[0128] In some embodiments, after the controller determines the actual light intensity and the predicted light intensity at the second moment, it can determine the target power supply mode of the air conditioning system according to the actual light intensity and the predicted light intensity. Figure 8 It is a schematic flowchart of another control method for the air conditioning system provided by the embodiment of the present application, which is used for the target power supply mode of the air conditioning system, as Figure 8 shown. The method includes the following steps:

[0129] S401. When the actual light intensity is less than or equal to the product of the predicted light intensity and the light correction coefficient, the controller determines that the target power supply mode of the air conditioner is to supply power through the energy storage device.

[0130] It should be noted that the light correction coefficient is used to make up for the situation where the light radiation intensity and the light intensity prediction are on the high side. Its value is associated and matched with the accuracy of the light prediction model, and its value can be gradually corrected according to the operation of the whole set of equipment.

[0131] Optionally, the light correction coefficient can be β.

[0132] In some embodiments, when the actual light intensity is less than or equal to the product of the predicted light intensity and the light correction coefficient, it means that the actual light intensity at the second moment is approximately equal to, slightly less than, or much less than the predicted light intensity. At this time, the electric energy converted by the light intensity may not be able to maintain the stable operation of the air conditioner. Therefore, it is necessary to control the energy storage device of the air conditioning system to turn on to supply power to the air conditioner.

[0133] Exemplarily, taking within one hour after the sun rises as an example, the average value of the multiple actual light intensities detected by the light detection device is the actual light intensity, and the average value of the multiple predicted light intensities in the corresponding time period predicted by the light prediction device at the first moment is the predicted light intensity.

[0134] Furthermore, when the actual light intensity Q1 is less than or equal to the product of the predicted light intensity Q2 and the light correction coefficient β, that is, when Q1 ≤ βQ2, the controller determines that the target power supply mode of the air conditioner is to supply power through the energy storage device.

[0135] S402. When the actual light intensity is greater than the product of the predicted light intensity and the light correction coefficient, the controller determines that the target power supply mode of the air conditioner is to be powered by the photovoltaic power generation device.

[0136] In some embodiments, when the actual light intensity is greater than the product of the predicted light intensity and the light correction coefficient, it indicates that the actual light intensity at the second moment is much greater than the predicted light intensity. At this time, the electric energy converted by the light intensity can maintain the stable operation of the air conditioner. Therefore, there is no need to supply power to the air conditioner through the energy storage device at this time. The controller controls the photovoltaic power generation device of the air conditioning system to turn on for power generation and supply power to the air conditioner.

[0137] Exemplarily, when the actual light intensity Q1 is greater than the predicted light intensity Q2 and greater than the product of the predicted light intensity and the light correction coefficient β, that is, when Q1 > βQ2, the controller determines that the target power supply mode of the air conditioner is to be powered by the photovoltaic power generation device.

[0138] S106. The controller controls the air conditioning system to supply power to the air conditioner based on the target power supply mode.

[0139] In some embodiments, after the target power supply mode of the air conditioning system is determined, the controller controls the air conditioning system to supply power to the air conditioner based on the target power supply mode.

[0140] In some embodiments, the controller can supply power to the air conditioner by controlling the scheduling device in the air conditioning system. Figure 9 The flowchart of another control method for the air conditioning system provided by the embodiments of the present application is used to control the scheduling device to supply power to the air conditioner. As Figure 9 shown, the method includes the following steps:

[0141] S501. When the target power supply mode of the air conditioner is to be powered by the energy storage device, the controller controls the scheduling device to turn on the current switch between the power system and the energy storage device.

[0142] Exemplarily, when the controller determines that the target power supply mode of the air conditioner is to be powered by the energy storage device, the controller controls the scheduling device to turn on the current switch between the power system and the energy storage device, so that the electric energy in the energy storage device flows to the air conditioner to supply power to the air conditioner.

[0143] S502. When the target power supply mode of the air conditioner is to be powered by the photovoltaic power generation device, control the scheduling device to turn off the current switch between the energy storage device and the air conditioner and turn on the current switch between the photovoltaic power generation device and the air conditioner.

[0144] Exemplarily, when the controller determines that the target power supply mode of the air conditioner is to be powered by a photovoltaic power generation device, there is no need to power the air conditioner through the energy storage device at this time. The controller controls the dispatching device to turn off the current switch between the energy storage device and the air conditioner, and turn on the current switch between the photovoltaic power generation device and the air conditioner, and the photovoltaic power generation device generates electricity to power the air conditioner.

[0145] In some embodiments, the power correction coefficient and the light correction coefficient can be natural numbers greater than 1, that is, α, β > 1.

[0146] Exemplarily, taking α and β as 1.1 as an example, during the commissioning and operation stage of the air conditioning system, record the predicted light radiation intensity, predicted light intensity, actual photovoltaic power generation, predicted light intensity, and the input power required for the stable operation of the air conditioner at each time period from sunrise to sunset every day (such as from 8:00 am to 16:00 pm, a total of 8 hours), form their respective data matrices, which are represented by G, K, L, M, and N respectively, and convert the predicted light radiation intensity into a photovoltaic power generation amount matrix J.

[0147] Furthermore, taking a week as the value period and one hour as the recording unit, each functional matrix respectively contains 56 groups of data.

[0148] In some embodiments, take a set of numbers from matrix J and matrix L in sequence, such as (J1, L1), then (J1, L1), …, (J 56 , L 56 ) can be formed, a total of 56 groups of numbers. Calculate the ratio of each group of data, that is, the ratio of the predicted power generation amount per hour of the photovoltaic power generation device to the actual power generation amount, and record it as matrix X.

[0149] In some embodiments, take a set of numbers from matrix K and matrix M in sequence as (K1,

[0150] M1), then (K1, M1), …, (K 56 , M 56 ) can be formed, a total of 56 groups of numbers. Calculate the ratio of each group of data, that is, the ratio of the predicted illuminance per hour of the photovoltaic power generation device to the actual illuminance, and record it as matrix Y.

[0151] In some embodiments, take a set of numbers from matrix J and matrix N in sequence as (J1, N1), then (J1, N1), …, (J 56 , N 56 ) can be formed, a total of 56 groups of numbers. Calculate the ratio of each group of data, that is, the ratio of the predicted power generation amount per hour of the photovoltaic power generation device to the actual air conditioner demand power, and record it as matrix Z.

[0152] It should be noted that the data of the above matrix X and matrix Y can be used as a reference for correcting the prediction model, and the model should be corrected as much as possible so that the ratio is between 0.8 and 1.3. The closer the ratio is to 1, the more accurate the prediction model is.

[0153] Furthermore, the value of α is the average of all data in matrix Z that is greater than 1, and the value of β is the average of all data in matrix Y that is greater than 1.

[0154] It should be noted that due to regional differences, the rising or setting time of the sun is inconsistent, and the matrix values should conform to the local actual situation. In addition, the self-correction frequency and variable value period of the α and β coefficients can be set. For example, the recording unit can be changed to 0.5 hours or 2 hours, and the value period can be changed to 3 days or two weeks, etc.

[0155] At the same time, the matrix data should be updated in real time, and data should be selected and discarded according to the settings of different value-taking schemes, and the prediction model and value-taking scheme should be continuously optimized according to the power supply allocation situation in the system.

[0156] The technical solution provided by the embodiment of the present application at least brings the following beneficial effects: By obtaining the predicted light intensity at the second moment at the first moment, this technical solution makes a preliminary prediction of the weather condition and light intensity at the second moment, and determines whether the electricity generated by the predicted light intensity can meet the stable operation of the air conditioner according to the predicted light intensity and the input power of the air conditioner in the stable operation state, so as to select the target energy storage method of the air conditioning system, avoiding waste of electric power resources; In addition, the actual light intensity is obtained at the second moment, and the target power supply method of the air conditioner is determined according to the predicted light intensity and the actual light intensity, so as to avoid that the initial power supply method is insufficient to support the stable operation of the air conditioner. In this way, an air conditioning system with stable energy storage, reasonable power supply and independent operation is formed.

[0157] In some embodiments, the above steps S201 - step S202, steps S301 - step S302 can also be implemented by the method as Figure 10 shown, Figure 10 which is a schematic flowchart of another control method of the air conditioning system provided by the embodiment of the present application, used to determine the energy storage method of the air conditioning system, as Figure 10 shown, and this method includes the following steps:

[0158] S11. The controller obtains the predicted light intensity.

[0159] Optionally, the controller can obtain the predicted light intensity at a future moment through a light prediction device.

[0160] S12. The controller obtains the output power P1 of the photovoltaic power generation device to convert the predicted light intensity into electric energy.

[0161] Optionally, the controller may obtain, through an optoelectronic conversion device, the output power P1 of the photovoltaic power generation device that converts the predicted light intensity into electric energy.

[0162] In some embodiments, after the controller obtains the predicted light intensity at a future moment through the light prediction device, the predicted light intensity is input into the optoelectronic conversion device to calculate the output power P1 of the predicted light intensity converted into electric energy.

[0163] S13. When P1 ≤ αP2, determine that the target energy storage mode of the air conditioning system is to purchase electricity from the power system and store it in the energy storage device.

[0164] Wherein, P2 is the input power of the air conditioner in a stable operating state.

[0165] S14. When P1 > αP2, determine that the target energy storage mode of the air conditioning system is not to store energy.

[0166] In some embodiments, the above steps S401 - S402 can also be implemented by the method as Figure 11 shown, Figure 11 which is a schematic flowchart of another control method for an air conditioning system provided by an embodiment of the present application, used to determine the power supply mode of the air conditioning system, as Figure 11 shown, and this method includes the following steps:

[0167] S21. The controller obtains the actual light intensity Q1 and the predicted light intensity Q2.

[0168] S22. When Q1 ≤ βQ2, the controller determines that the target power supply mode of the air conditioner is to supply power through the energy storage device.

[0169] S24. When Q1 > βQ2, the controller determines that the target power supply mode of the air conditioner is to supply power through the energy storage device.
