[0002] The negative environmental impact of increasing carbon emissions is becoming increasingly significant, and low-carbon and carbon reduction have become a consensus for human societal development. The combustion of fossil fuels during electricity production emits large amounts of carbon dioxide. The efficiency and carbon emissions per unit capacity of thermal power units vary under different load rates; therefore, under dynamic electricity demand, the carbon emission factor is a variable that changes with the electricity supply and demand situation. Furthermore, due to the future integration of large amounts of wind and solar power into the power system, the randomness and volatility of renewable electricity will lead to even more drastic changes in carbon emissions per unit of electricity generated. Air conditioning systems constitute a major component of building electricity consumption, possessing the characteristics of ease of control and high dispatchability potential. Therefore, adjusting the real-time operating power of the air conditioning system can achieve overall carbon emission reduction over a long-term perspective. Existing air conditioning control methods are mostly constant temperature control, and the operating status of the air conditioner is related to the indoor set temperature. Air conditioning load clusters are distributed at the ends of the building, thus increasing communication and control costs in actual control. Summary of the Invention

Then, based on the target carbon emission and the carbon emission characteristic values, a target mapping relationship is queried to obtain a target formula, and each of the first target temperatures is updated according to the target formula to obtain a corresponding second target temperature. The target mapping relationship is the mapping relationship between the target carbon emission, the carbon emission characteristic values, and the target formula, and the target formula is used to update the first target temperature. Finally, based on the second target temperature, each of the air conditioners in the air conditioning unit is controlled to operate until a third target temperature is less than or equal to the second target temperature, where the third target temperature is the actual indoor temperature.

[0029] This embodiment provides a carbon emission-based air conditioning control method that runs on a mobile terminal, computer terminal, or similar computing device. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Also, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0030] Figure 2 is a flowchart of an air conditioning control method based on carbon emissions according to an embodiment of this application. As shown in Figure 2, the method includes the following steps:

[0031] Step S201: Obtain target carbon emissions, multiple first target temperatures, and multiple carbon emission characteristic values. The target carbon emissions are the real-time carbon emissions of the air conditioning unit. The first target temperatures are the set indoor temperatures corresponding to each air conditioner in the air conditioning unit. The carbon emission characteristic values ​​are the carbon emission nodes for adjusting the set indoor temperature of the air conditioning unit.

[0032] Specifically, as shown in Figure 3, the air conditioning unit acquires the real-time carbon emission signal of the air conditioning system during operation, and acquires the set of carbon emission signals over a period of time to determine the target carbon emission and multiple carbon emission characteristic values, and acquires the current indoor temperature set value of each air conditioner to obtain the first target temperature.

[0033] Step S202: Based on the target carbon emissions and the carbon emission characteristic values, query the target mapping relationship to obtain the target formula, and update each of the first target temperatures according to the target formula to obtain the corresponding second target temperature. The target mapping relationship is the mapping relationship between the target carbon emissions and the carbon emission characteristic values ​​and the target formula. The target formula is used to update the first target temperature.

[0034] Specifically, multiple carbon emission ranges are determined based on the aforementioned carbon emission characteristic values. Based on the aforementioned carbon emission ranges, a corresponding target formula is determined. The aforementioned first target temperature is substituted into the aforementioned target formula to obtain the aforementioned second target temperature.

[0035] Step S203: Control each air conditioner in the air conditioning unit to operate according to the second target temperature until the third target temperature is less than or equal to the second target temperature, where the third target temperature is the actual indoor temperature.

[0036] Specifically, the second target temperature is sent to each of the aforementioned air conditioners to reset the set indoor temperature of each air conditioner. Then, each air conditioner adjusts the temperature according to the preset control strategy until the indoor temperature is less than or equal to the set indoor temperature. That is, the air conditioners in the aforementioned air conditioning unit are controlled to operate until the third target temperature is less than or equal to the second target temperature.

[0037] In this embodiment, firstly, a target carbon emission, multiple first target temperatures, and multiple carbon emission characteristic values ​​are obtained. The target carbon emission is the real-time carbon emission of the air conditioning unit, the first target temperature is the set indoor temperature corresponding to each air conditioner in the air conditioning unit, and the carbon emission characteristic values ​​are the carbon emission nodes used to adjust the set indoor temperature of the air conditioning unit. Then, a target formula is obtained by querying the target mapping relationship based on the target carbon emission and the carbon emission characteristic values, and the corresponding second target temperature is obtained by updating each of the first target temperatures according to the target formula. The target mapping relationship is the mapping relationship between the target carbon emission, the carbon emission characteristic values, and the target formula, and the target formula is used to update the first target temperature. Finally, the operation of each air conditioner in the air conditioning unit is controlled according to the second target temperature until a third target temperature is less than or equal to the second target temperature, where the third target temperature is the actual indoor temperature. This application adjusts the setpoint of the operating temperature based on the relationship between real-time carbon emissions and characteristic values. When real-time carbon emissions are relatively high, the indoor setpoint temperature is increased and the operating power of the air conditioning unit is reduced. When real-time carbon emissions are relatively low, the indoor setpoint temperature is decreased and the operating power of the air conditioning unit is increased, so that carbon emissions are kept within a certain range. While ensuring that the indoor temperature meets the requirements, the air conditioning is operated in a low-carbon manner as much as possible, which solves the problem that there is no method in the prior art to reduce power consumption to reduce carbon emissions from power generation.

[0038] To obtain the aforementioned carbon emission characteristic values, in one optional embodiment, the method further includes the following step before obtaining the carbon emission characteristic values:

[0039] Step S301: Obtain the historical dataset of the target carbon emissions within the target time period, where the end time of the target time period is the current time and the duration of the target time period is a preset duration.

[0040] Specifically, the real-time carbon emission signal C(τ) is acquired, and then the historical dataset Acc[τ-T,τ] of the carbon emission signal within the preset time period before the current time is updated according to the preset statistical period, i.e. the preset time period mentioned above, where τ is the current time and T is the preset time period mentioned above.

[0041] Step S302: Determine the first feature value, the second feature value, and the third feature value based on the aforementioned historical dataset. The first feature value is the maximum value of the samples in the aforementioned historical dataset, the second feature value is the minimum value of the samples in the aforementioned historical dataset, and the third feature value is the average value of the samples in the aforementioned historical dataset.

[0042] Specifically, after obtaining the aforementioned historical dataset, the following steps are performed according to formula C. max =max(Acc[τ-T,τ]), C min=min(Acc[τ-T,τ]) and C mean =mean(Acc[τ-T,τ]), calculates the maximum, minimum, and average values ​​of carbon emission signals in the above historical dataset. This yields the first, second, and third eigenvalues.

[0043] To obtain the aforementioned second target temperature, in one optional implementation, step S202 includes:

[0044] Step S2021: If the target carbon emission is greater than the first characteristic value, the first preset temperature is determined as the second target temperature, and the first preset temperature is the maximum value that the indoor temperature can be set to.

[0045] Specifically, let the second target temperature mentioned above be T. set The first target temperature mentioned above is T. * set The first preset temperature mentioned above is T. set，upper When C(τ) is greater than C max In the case of formula T set =T set，upper The above T set，upper Give T set This means that the first target temperature is updated to obtain the second target temperature.

[0046] Step S2022: If the target carbon emission is less than the second characteristic value, the second preset temperature is determined as the second target temperature, which is the minimum value that the indoor temperature can be set to.

[0047] Specifically, the second preset value is set to T. set，lower When C(τ) is less than C min In the case of formula T set =T set，lower The above T set，lower Give T set This means that the first target temperature is updated to obtain the second target temperature.

[0048] To obtain the aforementioned second target temperature, in an optional implementation, step S202 further includes:

[0049] Step S2023: When the target carbon emission is less than or equal to the first characteristic value and greater than the third characteristic value, calculate the difference between the first preset temperature and the first target temperature to obtain a first temperature deviation, calculate the difference between the first characteristic value and the third characteristic value to obtain a first carbon emission deviation, and calculate the difference between the target carbon emission and the third characteristic value to obtain a second carbon emission deviation.

[0050] Specifically, when C(τ) is less than or equal to C max And C(τ) is greater than C mean In the case of formula Calculate the first temperature deviation mentioned above, according to formula C. max -C mean The first carbon emission deviation mentioned above is calculated using the formula C(τ)-C mean Calculate the second carbon emission deviation mentioned above.

[0051] Step S2024: Calculate the quotient of the first temperature deviation and the first carbon emission deviation, and calculate the sum of the product of the quotient and the second carbon emission deviation with the first target temperature to obtain the second target temperature.

[0052] Specifically, according to the formula Substituting the first temperature deviation, the first carbon emission deviation, and the second carbon emission deviation into the above, the second target temperature is obtained.

[0053] To obtain the aforementioned second target temperature, in an optional implementation, step S202 further includes:

[0054] Step S2025: When the target carbon emission is less than or equal to the third characteristic value and greater than or equal to the second characteristic value, calculate the difference between the first target temperature and the second preset temperature to obtain the second temperature deviation, calculate the difference between the third characteristic value and the second characteristic value to obtain the third carbon emission deviation, and calculate the difference between the third characteristic value and the target carbon emission to obtain the fourth carbon emission deviation.

[0055] Specifically, when C(τ) is less than or equal to C mean And C(τ) is greater than or equal to C min In this case, calculate according to the formula The aforementioned second temperature deviation, according to formula C mean -C min Calculate the third carbon emission deviation mentioned above, according to formula C. min -C(τ) is used to calculate the fourth carbon emission deviation mentioned above.

[0056] Step S2026: Calculate the quotient of the second temperature deviation and the third carbon emission deviation, and calculate the difference between the first target temperature and the product of the quotient and the fourth carbon emission deviation to obtain the second target temperature.

[0057] Specifically, according to the formula Substituting the above-mentioned second temperature deviation, third carbon emission deviation, and fourth carbon emission deviation, we obtain the above-mentioned second target temperature.

[0058] To reduce carbon emissions from air conditioning, in one optional implementation, step S203 includes:

[0059] Step S2031: Obtain the third target temperature. If the third target temperature is higher than the second target temperature and the target carbon emission is greater than the first characteristic value, control the air conditioner to cool at the first preset power until the third target temperature is equal to the second target temperature.

[0060] Specifically, the current actual indoor temperature corresponding to the air conditioner is obtained, and the aforementioned third target temperature is denoted as T. When T is greater than T... set And C(τ) is greater than C max In this case, control the air conditioner to cool at a low power P1 until T = T set By increasing the set temperature, the power consumption of the air conditioner can be reduced, thus reducing carbon emissions.

[0061] Step S2032: When the third target temperature is higher than the second target temperature and the target carbon emission is less than or equal to the first characteristic value and greater than the third characteristic value, the air conditioner is controlled to cool at the second preset power until the third target temperature is equal to the second target temperature and the second preset power is greater than the first preset power.

[0062] Specifically, when T is greater than T set C(τ) is less than or equal to C max And C(τ) is greater than C mean In this case, control the air conditioner to cool at a lower power P2 until T = T set By increasing the set temperature, the power consumption of the air conditioner can be reduced, thus reducing carbon emissions.

[0063] Step S2033: When the third target temperature is higher than the second target temperature and the target carbon emission is less than or equal to the third characteristic value and greater than or equal to the second characteristic value, the air conditioner is controlled to cool at a third preset power until the third target temperature is equal to the second target temperature and the third preset power is greater than the second preset power.

[0064] Specifically, when T is greater than T set And C(τ) is less than or equal to C mean And C(τ) is greater than or equal to C min Under these circumstances, if the current carbon emissions of the air conditioner are determined to be low, priority should be given to increasing the power to lower the temperature, and the air conditioner should be controlled to cool at a higher power P3 to ensure the cooling effect.

[0065] In step S2034, when the third target temperature is higher than the second target temperature and the target carbon emission is less than the second characteristic value, the air conditioner is controlled to cool at a fourth preset power until the third target temperature is equal to the second target temperature and the fourth preset power is greater than the third preset power.

[0066] Specifically, when T is greater than T set And C(τ) is less than C min Under these circumstances, if the current air conditioner's carbon emissions are determined to be low, priority should be given to increasing its power to lower the temperature. The air conditioner should be controlled to use a high-power P4 for cooling to ensure the cooling effect.

[0067] To reduce carbon emissions from air conditioning, in one optional implementation, step S203 further includes:

[0068] Step S2035: If the third target temperature is less than or equal to the second target temperature, turn off the air conditioner.

[0069] Specifically, when T is less than or equal to T set If the current indoor temperature meets the requirements, in order to reduce carbon emissions, only adjust the set temperature and turn off the air conditioner until the indoor temperature is higher than the set temperature.

[0070] To enable those skilled in the art to better understand the technical solution of this application, the implementation process of the carbon emission-based air conditioning control method of this application will be described in detail below with reference to specific embodiments.

[0071] This embodiment relates to a specific air conditioning control method based on carbon emissions, as shown in Figure 4, which includes the following steps:

[0072] Step S1: Acquire real-time electricity carbon emission signal C(τ);

[0073] Step S2: Update the historical carbon signal data set Acc[τ-T,τ]. The length of the historical dataset is the statistical period T. Update the dataset in real time based on the real-time carbon emission signals obtained in S1.

[0074] Step S3: Calculate the eigenvalues ​​of carbon emission signals within the historical data set Acc[τ-T,τ]: maximum value C max Minimum value C min Average C mean ;

[0075] Step S4: The air conditioning system adjusts the operating temperature setpoint based on the basic relationship between real-time carbon emission signals and characteristic values. The formula is as follows:

[0076] Step S5: The air conditioning unit adjusts its actual operating power based on the difference between the actual indoor temperature and the greenhouse temperature setting, thereby changing the carbon emissions of the unit.

[0077] It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.
