Detailed Implementation

[0023] 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.

[0024] 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: Collect the current operating power value of the air conditioner; Step S12: After the air conditioner enters the response state, it uses the current operating power value as the reference power value and controls the actual operating power of the air conditioner according to the time sequence and level of the control command.

[0025] It is understood that the technical solution provided in this embodiment, by collecting the current operating power value of the air conditioner, and after the air conditioner enters the response state, uses the current operating power value as the reference power value, and controls the actual operating power of the air conditioner according to the time sequence and level of the control command, can adjust the actual operating power according to the control command, and avoid safety risks caused by the air conditioner running during the peak period of the power grid load.

[0026] In practice, the air conditioner executes a control command only once in each response state. The control command carries duration information. The air conditioner executes the control command until the duration ends and then exits the response state.

[0027] 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.

[0028] In practical application, if the air conditioner is connected to the power grid energy management platform, the method for controlling the actual operating power of the air conditioner is as follows: When the air conditioner receives the control command issued by the power grid energy management platform for the first time, it controls the actual operating power of the air conditioner according to the first control strategy. When the air conditioner receives a control command from the power grid energy management platform for the second time, it controls the actual operating power of the air conditioner according to the second control strategy. When the air conditioner receives the control command from the power grid energy management platform for the third time, it controls the actual operating power of the air conditioner according to the third control strategy. When the air conditioner receives the control command from the power grid energy management platform for the fourth time, it controls the actual operating power of the air conditioner according to the fourth control strategy.

[0029] It should be noted that 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 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.

[0030] 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.

[0031] It is understood that the technical solution provided in this embodiment uses different control strategies to control the actual operating power of the air conditioner according to the time sequence of the control commands received by the air conditioner from the power grid energy management platform. On the one hand, it can support the stability of the power grid supply and avoid safety risks caused by the air conditioner running during the peak period of the power grid load. On the other hand, it can also avoid a sudden drop in the actual operating power of the air conditioner and ensure the user's experience.

[0032] In practice, controlling the actual operating power of the air conditioner according to the first control strategy specifically means: If the control command is at level one, the actual operating power of the air conditioner will be the reference power value. First preset ratio; If the control command is at level two, the actual operating power of the air conditioner will be the reference power value. Second preset ratio; If the control command is at level three, the actual operating power of the air conditioner will be the reference power value. Third preset ratio; The first preset ratio is greater than the second preset ratio, and the second preset ratio is greater than the third preset ratio.

[0033] 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%.

[0034] It is understood that the technical solution provided in this embodiment controls the actual operating power of the air conditioner according to the level of the first control command. On the one hand, it can support the stability of the power grid supply and avoid safety risks caused by the air conditioner operating during peak grid load periods. On the other hand, it can also prevent the actual operating power of the air conditioner from dropping sharply, thus ensuring the user experience.

[0035] In practice, controlling the actual operating power of the air conditioner according to the second control strategy specifically means: When the air conditioner receives a control command from the power grid energy management platform for the second time, if the first control command was of the first level, the actual operating power of the air conditioner will be controlled according to the first sub-control strategy. If the first control command is at the second level, the actual operating power of the air conditioner is controlled according to the second sub-control strategy. If the first control command is at the third level, the actual operating power of the air conditioner will be controlled according to the third sub-control strategy.

[0036] In practice, controlling the actual operating power of the air conditioner according to the first sub-control strategy specifically means: If the second control command is at the first level, then the actual operating power of the air conditioner will be the reference power value. First preset ratio Fourth preset ratio; If the second control command is at the second level, then the actual operating power of the air conditioner will be the reference power value. First preset ratio Fifth preset ratio; If the second control command is at level three, then the actual operating power of the air conditioner will be the reference power value. First preset ratio Sixth preset ratio; The fourth preset ratio is greater than the fifth preset ratio, and the fifth preset ratio is greater than the sixth preset ratio.

[0037] It should be noted that the fourth, fifth, and sixth preset ratios are empirical values ​​or set according to actual work needs, such as setting the fourth preset ratio to 56.25%, the fifth preset ratio to 37.5%, and the sixth preset ratio to 18.75%.

[0038] In practice, controlling the actual operating power of the air conditioner according to the second sub-control strategy specifically means: If the second control command is at the first level, then the actual operating power of the air conditioner will be the reference power value. Second preset ratio Seventh preset ratio; If the second control command is at the second level, then the actual operating power of the air conditioner will be the reference power value. Second preset ratio Eighth preset ratio; If the second control command is at level three, then the actual operating power of the air conditioner will be the reference power value. Second preset ratio Ninth preset ratio; The seventh preset ratio is greater than the eighth preset ratio, and the eighth preset ratio is greater than the ninth preset ratio.

[0039] It should be noted that the seventh, eighth, and ninth preset ratios are empirical values ​​or set according to actual work needs. For example, the fourth preset ratio is set to 37.5%, the fifth preset ratio to 25%, and the sixth preset ratio to 12.5%.

[0040] In practice, the control of the actual operating power of the air conditioner according to the third sub-control strategy is specifically as follows: For the second control command at any level, the actual operating power of the air conditioner is controlled to be the minimum operating power.

[0041] It is understood that the technical solution provided in this embodiment, when the air conditioner receives the control command issued by the power grid energy management platform for the second time, adopts different sub-control strategies to further control the actual operating power of the air conditioner based on the first control command. On the one hand, it can support the stability of the power grid supply and avoid safety risks caused by the air conditioner running during the peak period of the power grid load. On the other hand, it can also avoid a sudden drop in the actual operating power of the air conditioner and ensure the user's experience.

[0042] In practice, controlling the actual operating power of the air conditioner according to the third control strategy specifically means: When the air conditioner receives the control command issued by the power grid energy management platform for the third time, if the first control command is at the first or second level, the actual operating power of the air conditioner will be controlled according to the fourth sub-control strategy. If the first control command is at the third level, the actual operating power of the air conditioner will be controlled according to the fifth sub-control strategy.

[0043] In practice, the control of the actual operating power of the air conditioner according to the fourth sub-control strategy is specifically as follows: For the third control command at any level, the actual operating power of the air conditioner is controlled to be the minimum operating power.

[0044] It should be noted that if the first control command is at level one or level two, the actual operating power of the air conditioner is already relatively low after two control commands. Therefore, for the third control command at any level, the actual operating power of the air conditioner can be directly reduced to the minimum operating power, which can also avoid damage to the air conditioner caused by repeated power adjustments.

[0045] In practice, controlling the actual operating power of the air conditioner according to the fifth sub-control strategy specifically means: For any level of the third control command, the air conditioner is controlled to enter the shutdown state.

[0046] It should be noted that if the first control command is level three, the air conditioner will already be operating at the minimum operating power after the second control command is executed. Therefore, for any level of the third control command, the air conditioner will be directly controlled to enter the shutdown state.

[0047] It is understood that the technical solution provided in this embodiment, when the air conditioner receives the control command issued by the power grid energy management platform for the third time, adopts different sub-control strategies to further control the actual operating power of the air conditioner based on the first and second control commands. On the one hand, it can support the stability of the power grid supply and avoid safety risks caused by the air conditioner running during the peak period of the power grid load. On the other hand, it can also avoid a sudden drop in the actual operating power of the air conditioner and ensure the user's experience.

[0048] In practice, controlling the actual operating power of the air conditioner according to the fourth control strategy specifically means: When the air conditioner receives a control command from the power grid energy management platform for the fourth time, it will shut down the air conditioner for any level of the fourth control command.

[0049] It should be noted that when the air conditioner receives the control command issued by the power grid energy management platform for the fourth time, the actual operating power of the air conditioner will definitely be the minimum operating power, so the air conditioner will be directly controlled to enter the shutdown state.

[0050] It is understood that the technical solution provided in this embodiment controls the air conditioner to enter a shutdown state when the air conditioner receives the control command issued by the power grid energy management platform for the fourth time. This can both support the power supply demand of the power grid and avoid damage to the air conditioner caused by repeated power adjustments.

[0051] In practice, for any control command, if the control command is level four, the air conditioner will be controlled to enter the shutdown state.

[0052] It is understood that the technical solution provided in this embodiment, for any control command, if the control command is at the fourth level, controls the air conditioner to enter the shutdown state, which can provide the greatest support for the power supply demand of the power grid.

[0053] In practice, for any given control command, if the control command is level 5, the actual operating power of the air conditioner is controlled to be the actual operating power of the air conditioner after the last execution of the control command, and this is maintained until the duration ends.

[0054] It should be noted that for any control command, if the control command is level 5, the actual operating power of the air conditioner is the actual operating power of the air conditioner after the last execution of the control command, and this is maintained until the end of the duration. This ensures that the power supply demand of the power grid is not affected, and also guarantees the user experience.

[0055] In practice, for any control command, if the control command is level six, the air conditioner will exit the response state.

[0056] 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.

[0057] Example 2 A power control device 100 for an air conditioner, according to another exemplary embodiment, includes: The data acquisition module 101 is used to acquire the current operating power value of the air conditioner; The control module 102 is used to control the actual operating power of the air conditioner based on the current operating power value and according to the time sequence and level of the control commands after the air conditioner enters the response state.

[0058] It is understood that the technical solution provided in this embodiment includes a data acquisition module 101 and a control module 102 in the power control device 100 of the air conditioner. By acquiring the current operating power value of the air conditioner, after the air conditioner enters the response state, the current operating power value is used as the reference power value, and the actual operating power of the air conditioner is controlled according to the time sequence and level of the control command. The actual operating power can be adjusted according to the control command to avoid safety risks caused by the air conditioner running during the peak period of the power grid load.

[0059] Example 3 An air conditioner according to another exemplary embodiment includes: The power control device for the air conditioner.

[0060] It is understood that the technical solution provided in this embodiment sets up a power control device for the air conditioner. By collecting the current operating power value of the air conditioner, after the air conditioner enters the response state, the actual operating power of the air conditioner is controlled according to the time sequence and level of the control command, based on the current operating power value as the reference power value. This can adjust the actual operating power according to the control command and avoid safety risks caused by the air conditioner running during peak grid load periods.
