[0002] As socio-economic development drives rising living standards, coupled with climate change caused by human activities leading to more frequent extreme weather events, the demand for air conditioning continues to grow rapidly. Since air conditioning load is concentrated in the hundreds of hours of peak summer electricity consumption, simply increasing installed capacity on the grid side to meet short-term peak demand requires enormous investment and results in very limited equipment resource utilization, leading to a significant waste of social resources. Buildings generally have a certain heat storage capacity; switching on or off air conditioning systems or changing operating parameters in a short period may not be noticeable or have a significant impact on building users. Air conditioning equipment has the potential to proactively participate in demand-side management, reducing peak grid load and mitigating safety risks during peak grid periods by controlling the operation of air conditioning systems during these times.

Detailed Implementation

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] Example 1 Figure 1 This is a flowchart illustrating a power control method for an air conditioner according to an exemplary embodiment, such as... Figure 1 As shown, the method includes: Step S11: Obtain the target temperature value and collect the current operating power of the air conditioner; Step S12: After the air conditioner enters the response state, it uses the current operating power as the reference power and controls the actual operating power of the air conditioner according to the target temperature value and the control command level.

[0021] It is understood that the technical solution provided in this embodiment obtains the target temperature value and collects the current operating power of the air conditioner. After the air conditioner enters the response state, it uses the current operating power as the reference power and controls the actual operating power of the air conditioner according to the target temperature value and the control command level. On the one hand, it can ensure the user's temperature needs, and on the other hand, it can support the power supply capacity of the power grid and avoid the safety risks caused by the air conditioner running during the peak load period of the power grid.

[0022] In practice, the method also includes: Each time the air conditioner responds, it executes a control command only once. The control command carries duration information. The air conditioner executes the control command until the duration ends, and then exits the response state.

[0023] like Figure 2 As shown, the air conditioner's operating state is divided into user operating state and response state. The user operating state refers to adjusting the actual operating power of the air conditioner according to the user's set temperature. Only after receiving a control command in the user operating state will the air conditioner enter the response state. In the response state, the air conditioner controls the actual operating power according to the control command until the duration ends, then exits the response state and enters the user operating state. Because the air conditioner's power is limited, after executing multiple control commands, the actual support effect on the power grid's power supply capacity is already very weak. This also avoids the air conditioner malfunctioning due to repeated control of its actual operating power.

[0024] In practice, the method for controlling the actual operating power of the air conditioner includes: If the control command is at the first level, the target operating power of the air conditioner is set to the reference power. The first preset ratio controls the actual operating power of the air conditioner based on the target operating power. If the control command is at the second level, the target operating power of the air conditioner is set to the reference power. The second preset ratio controls the actual operating power of the air conditioner based on the target operating power. If the control command is at level three, set the target operating power of the air conditioner to the reference power. The third preset ratio controls the actual operating power of the air conditioner based on the target operating power. The first preset ratio is greater than the second preset ratio, and the second preset ratio is greater than the third preset ratio.

[0025] It should be noted that the air conditioner is connected to the power grid energy management platform. The power grid energy management platform collects overall electricity consumption data and predicts power supply pressure. During periods of concentrated electricity consumption, when the power grid's power supply pressure is too high, it will send control commands to the air conditioner to reduce its actual operating power. This ensures the stability of the power grid supply on the one hand, and avoids safety risks caused by the air conditioner operating during peak power grid load periods on the other hand.

[0026] It should be noted that since the power grid energy management platform also connects to high-power electrical equipment such as charging piles, if the air conditioner is in a response state and cannot execute the new control command when the power grid energy management platform issues a control command, it will default to prioritizing the control of the actual operating power of other high-power electrical equipment to avoid a sudden drop in the actual operating power of the air conditioner and ensure the user experience.

[0027] It should be noted that the first, second, and third preset ratios are empirical values ​​or set according to actual work needs, such as setting the first preset ratio to 75%, the second preset ratio to 50%, and the third preset ratio to 25%.

[0028] It is understood that the technical solution provided in this embodiment controls the target operating power of the air conditioner according to the level of control instructions received by the air conditioner from the power grid energy management platform, which can support the stability of the power grid supply and avoid safety risks caused by the air conditioner operating during peak power grid load periods.

[0029] In practice, the method also includes: When the air conditioner starts executing control commands, it collects the ambient temperature value in real time and obtains a preset temperature deviation value, which is greater than zero. Calculate the absolute value of the difference between the ambient temperature value and the target temperature value to obtain the actual temperature deviation value; The actual operating power of the air conditioner is controlled based on the preset temperature deviation value and the actual temperature deviation value.

[0030] It should be noted that the target temperature value is set according to the user's actual temperature needs, and the preset temperature deviation value is an empirical value or set according to the user's actual needs. For example, if the target temperature value is set to 25°C and the preset temperature deviation value is 3°C, then the acceptable ambient temperature range for the user is 22°C to 28°C. Based on the preset temperature deviation value and the actual temperature deviation value, the actual operating power of the air conditioner is controlled to avoid the reduction of the air conditioner power causing the ambient temperature value to exceed the user's acceptable range, thus ensuring the user's temperature needs.

[0031] In practice, the method for controlling the actual operating power of the air conditioner based on the preset temperature deviation value and the actual temperature deviation value includes: If the actual temperature deviation value is less than the preset temperature deviation value, a preset temperature margin is obtained, wherein the preset temperature margin is greater than zero. The actual temperature margin is obtained by subtracting the actual temperature deviation value from the preset temperature deviation value. The actual operating power of the air conditioner is controlled based on the preset temperature margin and the actual temperature margin.

[0032] It should be noted that ambient temperature has thermal inertia. When the actual temperature deviation is close to the preset temperature deviation, the preset temperature margin is used to allow for a slow change in the environment. The preset temperature margin is an empirical value or is set according to actual working needs. For example, if the preset temperature margin is set to 0.5°C and the preset temperature deviation is set to 3°C, when the actual temperature deviation is 2.5°C, the air conditioner will maintain its current operating power until the end of the duration. This can improve the accuracy of temperature control and ensure the user's temperature needs.

[0033] In practice, the method also includes: If the actual temperature deviation value is equal to the preset temperature deviation value, the current operating power of the air conditioner is maintained until the duration ends.

[0034] It is understood that the technical solution provided in this embodiment, if the actual temperature deviation value is equal to the preset temperature deviation value, maintains the current operating power of the air conditioner until the end of the duration, which can prevent the ambient temperature value from exceeding the user's acceptable range and ensure the user's temperature needs.

[0035] In practice, the method also includes: If the actual temperature deviation is greater than the preset temperature deviation, the air conditioner increases its actual operating power until the actual temperature deviation equals the preset temperature deviation, and then maintains the current operating power of the air conditioner until the duration ends.

[0036] It should be noted that environmental factors may affect the ambient temperature, causing it to exceed the user's acceptable temperature range. In this case, by increasing the actual operating power of the air conditioner, the temperature can be restored to the user's acceptable temperature range, thereby ensuring the user's temperature needs are met.

[0037] In practice, the method for controlling the actual operating power of the air conditioner based on the preset temperature margin and the actual temperature margin includes: If the actual temperature margin is equal to the preset temperature margin, maintain the current operating power of the air conditioner until the duration ends; If the actual temperature margin is greater than the preset temperature margin, the actual operating power of the air conditioner is continuously adjusted until the actual operating power of the air conditioner equals the target operating power, and the current operating power of the air conditioner is maintained until the end of the duration.

[0038] It is understood that the technical solution provided in this embodiment controls the actual operating power of the air conditioner based on the relationship between the actual temperature margin and the preset temperature margin, which can support the power supply capacity of the power grid on the one hand, and ensure the user's temperature needs on the other hand.

[0039] In practice, the method also includes: If the control command is at level four, the air conditioner will be shut down.

[0040] It is understood that the technical solution provided in this embodiment, if the control command is at the fourth level, controls the air conditioner to enter the shutdown state, which can provide maximum support for the power supply capacity of the power grid.

[0041] In practice, the method also includes: If the control command is level 5, maintain the current operating power of the air conditioner until the duration ends.

[0042] It is understood that the technical solution provided in this embodiment, if the control command is level 5, maintains the current operating power of the air conditioner until the end of the duration, which can both avoid affecting the power supply capacity of the power grid and ensure the user experience.

[0043] In practice, the method also includes: If the control command is level six, control the air conditioner to exit the response state.

[0044] It should be noted that since the air conditioner can only execute the current control command in the response state, it can be exited from the response state through the sixth level control command. This means that the actual operating power of the air conditioner can be maintained without reducing it when the power supply capacity of the power grid has been stabilized. It can also exit the response state of the current control command to receive new control commands, thereby improving the flexibility of the actual operating power control of the air conditioner.

[0045] Example 2 Figure 3 This is a schematic diagram of the structure of a power control device 100 for an air conditioner according to another exemplary embodiment, comprising: The acquisition module 101 is used to acquire the target temperature value; The data acquisition module 102 is used to acquire the current operating power of the air conditioner; The control module 103 is used to control the actual operating power of the air conditioner based on the current operating power as the reference power, the target temperature value, and the control command level after the air conditioner enters the response state.

[0046] It is understood that the technical solution provided in this embodiment includes an acquisition module 101, a collection module 102, and a control module 103 in the power control device 100 of the air conditioner, thereby acquiring the target temperature value and collecting the current operating power of the air conditioner. After the air conditioner enters the response state, it uses the current operating power as the reference power and controls the actual operating power of the air conditioner according to the target temperature value and the control command level. On the one hand, it can ensure the user's temperature needs, and on the other hand, it can support the power supply capacity of the power grid and avoid safety risks caused by the air conditioner running during the peak load period of the power grid.

[0048] It is understood that the technical solution provided in this embodiment sets up a power control device 100 in the air conditioner to obtain the target temperature value and collect the current operating power of the air conditioner. After the air conditioner enters the response state, it uses the current operating power as the reference power and controls the actual operating power of the air conditioner according to the target temperature value and the control command level. On the one hand, it can ensure the user's temperature needs, and on the other hand, it can support the power supply capacity of the power grid and avoid the safety risks caused by the air conditioner running during the peak load period of the power grid.
