[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 of power generation 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 large-scale integration of wind and solar power into the future power system, the randomness and volatility of renewable electricity will lead to even more drastic changes in carbon emissions per unit of electricity generation. Buildings, as end-users of the power system, constitute a major component of electricity consumption. Moreover, building electricity users can adjust their own power output, possessing a certain degree of dispatch flexibility.

[0031] Step S201: Obtain the target carbon emissions, multiple preset carbon emissions and a first target power, and determine the target range by matching the target carbon emissions with each of the preset carbon emissions. The target carbon emissions are the carbon emissions of the water heater at the current time, the first target power is the set output power of the water heater, and the target range is the carbon emission range to which the target carbon emissions belong.

[0032] Specifically, during the operation of the water heater, real-time carbon emission signals are monitored to determine the target carbon emission C(τ). Then, historical parameter sets are updated based on the real-time carbon emission, representing the carbon emissions over a period of time prior to the current moment. Multiple threshold values ​​are then determined based on these historical parameter sets to obtain the preset carbon emission. Finally, the current output power setting of the water heater is obtained to achieve the first target power.

[0033] Step S202: Based on the target interval, query the first mapping relationship to obtain the target formula, and substitute the first target power into the target formula to obtain the second target power. The target formula is a preset formula corresponding to the target interval, and the first mapping relationship is the mapping relationship between the carbon emission interval and the preset formula.

[0034] Specifically, the target formula is obtained by querying the preset formula based on the target interval, and then the first target power is substituted into the target formula to calculate the second target power.

[0035] Step S203: Obtain the target temperature, and control the water heater to operate according to the second target power until the temperature of the hot water in the water heater reaches the target temperature, which is the water temperature set by the user.

[0036] Specifically, the second target power is controlled to heat the water in the water heater until the water temperature in the water heater reaches the temperature set by the user.

[0037] In this embodiment, firstly, a target carbon emission, multiple preset carbon emissions, and a first target power are obtained. A target range is then determined by matching the target carbon emission with each of the preset carbon emissions. The target carbon emission is the carbon emission of the water heater at the current moment, the first target power is the set output power of the water heater, and the target range is the carbon emission range to which the target carbon emission belongs. Next, a target formula is obtained by querying a first mapping relationship based on the target range, and the first target power is substituted into the target formula to obtain a second target power. The target formula is a preset formula corresponding to the target range, and the first mapping relationship is the mapping relationship between the carbon emission range and the preset formula. Finally, a target temperature is obtained, and the water heater is controlled to operate according to the second target power until the temperature of the hot water in the water heater reaches the target temperature, which is the water temperature set by the user. This application, based on the relationship between carbon emissions and electricity supply and demand, calibrates a method for calculating the optimal power of a water heater corresponding to different carbon emission ranges. Then, based on the current set power of the water heater, a target set power is calculated, and the water heater is controlled to operate at the target set power to reduce carbon emissions caused by water heater power consumption. This method solves the problem of the lack of a control method in the prior art that uses real-time carbon signals to control different models and operating modes of water heaters to reduce carbon emissions.

[0038] In order to determine the target range based on the target carbon emissions and multiple preset carbon emissions, in an optional embodiment, step S201 includes:

[0039] Step S2011: Obtain the target signal, which is the carbon emission signal of the water heater within a preset time period. The end time of the preset time period is the current time, and the duration of the preset time period is the preset duration.

[0040] Specifically, the target signal C(x) is acquired, and the acquisition time of the target signal is t, with the preset duration being T. Then, the target signal is the carbon emission signal monitored by the sensor within the time period [tT, t].

[0042] Specifically, the target curve is obtained by plotting the corresponding signal curve based on the aforementioned carbon emission signals.

[0043] Step S2013: Determine the first preset carbon emission, the second preset carbon emission, and the third preset carbon emission based on the target curve. The first preset carbon emission is the maximum value of the peak value of the target curve, the second preset carbon emission is the minimum value of the trough value of the target curve, and the third preset carbon emission is the average value of the target curve.

[0044] Specifically, the target curve is analyzed to obtain multiple peak values ​​and multiple trough values ​​of the target signal, and the average carbon emissions within the preset time period are calculated based on integral operations to obtain C. mean Then, by comparing the peak values, the maximum value of the peak value is determined, and the maximum carbon emission C within the preset time period is obtained. max By comparing the trough values, the minimum trough value is determined, thus obtaining the minimum carbon emission value C within the preset time period. min That is, the first preset carbon emissions, the second preset carbon emissions, and the third preset carbon emissions are obtained.

[0045] Step S2014: The carbon emissions less than the second preset carbon emissions are defined as the first interval; the carbon emissions greater than or equal to the second preset carbon emissions and less than or equal to the third preset carbon emissions are defined as the second interval; the carbon emissions greater than the third preset carbon emissions and less than or equal to the first preset carbon emissions are defined as the third interval; and the carbon emissions greater than the first preset carbon emissions are defined as the fourth interval.

[0046] Specifically, since carbon emissions do not have negative values, therefore, [0, C] min ) is determined as the first interval mentioned above, and [C] is... min C mean [Identified as the second interval above, (C)] mean C max [Identified as the third interval above, (C)] max , +∞) is determined as the fourth interval mentioned above.

[0050] Step S2022: When the target carbon emissions are within the fourth range, the second preset power is determined as the second target power, and the first preset power is the lower limit of the output power of the water heater.

[0051] Specifically, when the target carbon emissions fall within the fourth range mentioned above, i.e., when C(τ) belongs to (C max In the case of (+∞), then according to formula P set =P set,upper , where P set,upper To achieve the second preset power, the power of the water heater is adjusted to the minimum power to reduce the carbon emissions of the water heater.

[0052] In order to obtain the first preset power and the second preset power, in an optional embodiment, before determining the first preset power as the second target power or the second preset power as the second target power, the method further includes:

[0053] Step S301: Obtain the target mode, which includes a first mode and a second mode. The first mode is for the user to set a first target water temperature, and the second mode is for the user to set a third target power.

[0054] Specifically, the system acquires the user-set water heater control commands and then determines the user-selected water heater operating mode based on the control commands. One operating mode is where the user controls the water heater to a preset water temperature t. u The first mode controls the water heater to heat the water to the target temperature. The second mode allows the user to control the water heater to operate at a preset heating power P. u Control the water heater to use heating power P u Running, i.e., the second mode mentioned above.

[0055] Step S302: When the target mode is the first mode, obtain the second target water temperature, which is the actual water temperature of the water heater at the current moment.

[0057] Step S303: When the target mode is the first mode and the second target water temperature is greater than the first target water temperature, both the first preset power and the second preset power are set to 0.

[0058] Specifically, when the second target water temperature is greater than or equal to the first target water temperature, it is determined that the water heater does not need to heat water, that is, the required output power of the water heater is 0. At this time, the upper limit and lower limit of the power output of the water heater are set to 0, that is, the first preset power and the second preset power are both determined to be 0.

[0059] Step S304: When the target mode is the first mode and the second target water temperature is lower than the first target water temperature, calculate the fourth target power based on the target flow rate, the first target water temperature and the second target water temperature, and query the second mapping relationship based on the fourth target power to obtain the first preset power and the second preset power. The second mapping relationship is the mapping relationship between the fourth target power and the first preset power and the second preset power.

[0060] Specifically, when the water heater is operating in the first mode described above and the second target water temperature is lower than the first target water temperature, it is determined that the water heater needs to heat water, and at this time, the target flow rate G is obtained. w The first target water temperature t mentioned above u And the second target water temperature t mentioned above w Then substitute it into formula P d =G w (tu-t w Calculate the fourth target power.

[0061] Step S305: When the target mode is the second mode, the first preset power and the second preset power are obtained by querying the third mapping relationship based on the third target power. The third mapping relationship is the mapping relationship between the third target power and the first preset power and the second preset power.

[0062] Specifically, when the water heater is operating in the second mode, the third target power set by the customer is the heating power required by the water heater. Then, based on the heat storage characteristics of the water heater tank, the third mapping relationship is consulted to obtain the minimum power P required to bring the second target water temperature to the first target water temperature. set,lower That is, the second preset power mentioned above, to obtain the highest power P that allows the second target water temperature to reach the first target water temperature. set,upper That is, the first preset power mentioned above.

[0063] In order to obtain the second target power based on the updated first target power, in an optional embodiment, step S202 further includes:

[0064] Step S2023: When the target carbon emissions are within the second range, calculate the difference between the first preset power and the first target power to obtain the first difference value.

[0067] Specifically, according to formula C max -C mean Calculate the second difference mentioned above, according to C(τ)-C mean Calculate the third difference mentioned above.

[0068] Step S2025: Calculate the product of the third difference and the first difference, the ratio of the product of the second difference and the first difference, and the sum of the first target power to obtain the second target power.

[0069] Specifically, substituting the first difference, the second difference, and the third difference into the following formula yields the second target power:

[0070]

[0071] In order to obtain the second target power based on the updated first target power, in an optional embodiment, step S202 further includes:

[0074] Step S2027: Calculate the difference between the third preset carbon emission and the second preset carbon emission to obtain the fifth difference value, and calculate the difference between the third preset carbon emission and the target carbon emission to obtain the sixth difference value.

[0075] Specifically, according to formula C mean -C min Calculate the fifth difference mentioned above, according to C. mean -C(τ) calculates the sixth difference mentioned above.

[0076] Step S2028: Calculate the ratio of the product of the fourth difference and the sixth difference to the fifth difference, and calculate the difference between the first target power and the ratio to obtain the second target power.

[0077] Specifically, substituting the aforementioned fourth difference, fifth difference, and sixth difference into the following formula yields the aforementioned second target power:

[0080] Step S2031: Obtain a third preset power and a fourth preset power, wherein the third preset power is less than the fourth preset power;

[0081] Specifically, when the water heater is a non-continuous gear adjustment, the power of each gear of the water heater is obtained, multiple gear ranges are determined, and then the lower limit value of each gear range is determined, the upper limit value of each gear range is determined, and then the upper and lower limits of the gear range to which it belongs are determined according to the second target power matching gear range, that is, the third preset power and the fourth preset power.

[0082] Step S2032: If the second target power is greater than the third preset power and less than the fourth preset power, the third preset power is determined as the fifth target power.

[0083] Specifically, after determining the above-mentioned gear range, the gear range is rounded down to obtain the power corresponding to the final operating gear of the water heater, which is the third preset power, and is determined as the fifth target power.

[0084] Step S2033: Control the operation of the water heater according to the fifth target power until the temperature of the hot water in the water heater reaches the target temperature.
