[0042] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0043] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0044] Existing conventional air conditioners always use indoor ambient temperature as the control target. Under extremely high temperature weather conditions, the peak of air conditioning power load is superimposed, or the local short-term power supply capacity of the photovoltaic storage direct flexible system is insufficient, which can easily cause unstable problems such as system power outages. Specifically, traditional air conditioners usually include an air conditioning temperature control unit and an air conditioning compressor operation control unit. The air conditioning temperature control unit only triggers the air conditioning compressor operation control unit to control the air conditioning compressor to reduce the operating frequency or increase the compressor operating frequency according to the demand for temperature control to meet the set appropriate temperature demand. It cannot achieve the fast and accurate power response of the flexible control that responds to the energy supply balance demand on the source side.

[0045] Based on the above, the present application provides a method, system, equipment and medium for direct control of air conditioning power. Through the flexible power consumption regulation of the load-side air conditioner, a method is provided for the photovoltaic storage direct flexible system to ensure stable and reliable operation of the system under extreme conditions, thereby avoiding the problem of forced power outages caused by overload peaks, and improving the safety, stability and reliability of the operation of the photovoltaic storage direct flexible system.

[0046] In order to solve the problem of forced power outage caused by overload due to the superposition of power consumption peak in the existing technology, Figure 1 A schematic diagram of the steps of a method for directly controlling air conditioner power provided in an embodiment of the present application. Figure 1 As shown, the air conditioner direct control method provided in the embodiment of the present application may include the following steps:

[0047] Step 110, obtaining a load target power control instruction;

[0048] Among them, the load target power control instruction may refer to an instruction for triggering the air-conditioning equipment to control the compressor operating frequency with the target power as the control target. For example, the load target power control instruction may be an energy control instruction issued by the photovoltaic storage direct and flexible system at an extreme peak power consumption point when the system load is heavy. The energy control instruction may include instruction parameter information such as a power direct control start flag and a target power setting value. The embodiments of the present application do not impose specific restrictions on this.

[0049] Step 120, determining the load target power and the current operating power of the air conditioning equipment based on the load target power control instruction;

[0050] Specifically, after obtaining the load power control instruction, the embodiment of the present application can determine the load target power according to the instruction parameter information carried by the load power control instruction. For example, when the instruction parameter information carried by the load power control instruction includes a target power setting value, the target power corresponding to the target power setting value is set as the load target power, and the air-conditioning equipment that needs to be controlled currently can be determined for the load power control instruction. Subsequently, sampling information of the current operating status of the air-conditioning equipment can be obtained to determine the current operating power of the air-conditioning equipment according to the sampling information of the current operating status, so that the current operating power of the air-conditioning equipment can be compared with the load target power to determine the air-conditioning control method according to the power comparison result.

[0051] Among them, the sampling information of the current operating status of the air-conditioning equipment may refer to the information collected for the current operating status of the air-conditioning equipment, which may specifically include but not be limited to: the current real-time operating power of the air-conditioning unit compressor and the unit operating status information, etc., which is not limited in the embodiments of the present application. It should be noted that the current real-time operating power of the air-conditioning unit compressor can be used to determine the current operating power of the air-conditioning equipment, the current operating power of the air-conditioning equipment may refer to the real-time operating power of the air-conditioning unit, and the unit operating status information can be used to determine the operating status of the air-conditioning unit.

[0052] The air conditioning control mode may refer to the control mode of the air conditioner. For example, the air conditioning control mode may be divided into a temperature control mode and a flexible power control mode. The temperature control mode may be used as a conventional control mode of the air conditioner. According to the demand for temperature control and in combination with the ambient temperature, the air conditioning compressor may be controlled to reduce the operating frequency or increase the operating frequency of the air conditioning compressor. The flexible power control mode may take the load target power as the control target, control the air conditioning equipment to reduce the operating frequency of the air conditioning compressor, so that the load power of the air conditioner does not exceed the load target power.

[0053] For example, when the air conditioning control mode is divided into temperature control mode and flexible power control mode, by judging whether the current operating power of the air conditioning equipment is greater than the load target power, it can be determined whether the air conditioning control mode is temperature control mode or flexible power control mode. Specifically, if the current operating power of the air-conditioning device is greater than the load target power, in order to avoid the problem of forced power outage due to overload caused by the superposition of power peaks, the flexible power consumption control mode can be determined as the air-conditioning control mode at this time, and based on the flexible power consumption control mode, the load target power is used as the control target of the air-conditioning device to control the air-conditioning device to reduce the operating frequency of the air-conditioning compressor, that is, execute step 130; if the current operating power of the air-conditioning device is not greater than the load target power, the conventional control mode of the air-conditioning compressor can be determined as the air-conditioning control mode at this time, and based on the conventional control mode of the air-conditioning compressor, according to the needs of temperature control, the air-conditioning compressor is controlled to reduce the operating frequency or increase the operating frequency of the air-conditioning compressor in combination with the ambient temperature. For example, when the ambient temperature is higher than the temperature set by the air-conditioning device, taking 26°C as the temperature set by the air-conditioning device as an example, if the ambient temperature is higher than 26°C, the power consumption of the compressor is increased, the output is increased to provide more cooling capacity, and the temperature of the room is reduced; after the room temperature reaches the temperature set by the air-conditioning device, if the ambient temperature is lower than the temperature set by the air-conditioning device, the compressor will reduce the power consumption, and the room temperature is repeatedly adjusted to stabilize near the set value.

[0054] Step 130 , when the current operating power is greater than the load target power, trigger the air-conditioning device to use the load target power as a control target and reduce the operating frequency of the compressor of the air-conditioning device.

[0055] It can be seen that the embodiment of the present application obtains the load target power control instruction to determine the load target power and the current operating power of the air-conditioning equipment based on the obtained load target power control instruction, and when the current operating power is greater than the load target power, triggers the air-conditioning equipment to use the load target power as the control target, reduces the operating frequency of the compressor of the air-conditioning equipment, and adjusts the air-conditioning load to reduce power, thereby achieving direct control of the air-conditioning load power consumption, thereby achieving rapid power response and meeting the needs of precise response and regulation, avoiding the problem of forced power outages caused by the superposition of power peaks, that is, solving the problem of forced power outages caused by the superposition of power peaks in the existing related technologies, and improving the power friendliness of the air-conditioning equipment.

[0056] In an embodiment of the present application, in order to build grid-load interaction and improve the power-friendlyness of air-conditioning equipment, the energy control instructions issued by the photovoltaic storage direct-flexible system can be received by the power adjustment component to achieve direct control of the power consumption of the air-conditioning load based on the energy control instructions. Optionally, the embodiment of the present application obtains the load target power control instruction, which can specifically include the following sub-steps:

[0057] Sub-step 1101, obtaining an energy control instruction sent by the solar-storage direct-flexible system;

[0058] Sub-step 1102, when the energy control instruction carries a power control start flag and a target power setting value, determining the energy control instruction as the load target power control instruction.

[0059] Specifically, the embodiment of the present application can receive the energy control instruction sent by the photovoltaic storage direct and flexible system through the air-conditioning power component, so as to obtain the energy control instruction sent by the photovoltaic storage direct and flexible system, and can detect the energy control instruction to detect whether the instruction parameter information carried by the energy control instruction includes the start-up power control flag and the target power setting value, so that the energy control instruction carrying the start-up power control flag and the target power setting value can be determined as the load target power control instruction, that is, when the energy control instruction carries the start-up power control flag and the target power setting value, the energy control instruction is determined as the load target power control instruction, so that the direct control of the air-conditioning load power can be achieved based on the load target power control instruction in the future, such as reducing the load power operation according to the target power set by the load target power control instruction during the period of tight source supply, thereby improving the stability, safety and reliability of the system operation.

[0060] Among them, the target power setting value refers to the power value set for the target power. Optionally, in order to adapt to the high proportion of renewable energy penetration in the future and improve the safety and reliability of power grid operation and load power consumption, after obtaining the load target power control instruction, the embodiment of the present application can determine the target power setting value carried by the load target power control instruction as the load target power, so that the air conditioning control method can be determined according to the load target power later. Furthermore, the embodiment of the present application determines the load target power and the current operating power of the air-conditioning equipment based on the load target power control instruction, and can specifically include the following sub-steps:

[0061] Sub-step 1201, determining the target power setting value carried in the load target power control instruction as the load target power;

[0062] Sub-step 1202, collecting current operation information of the air-conditioning equipment according to the load target power control instruction;

[0063] Sub-step 1203, determining the current operating power according to the current operating information.

[0064] It can be seen that after obtaining the load target power control instruction, the embodiment of the present application can determine the target power setting value carried by the load target power control instruction as the load target power, and can collect the current operating information of the air-conditioning equipment for the load target power control instruction, so as to determine the current operating power of the air-conditioning equipment in real time according to the current operating information, and then can determine the air-conditioning control method currently required by comparing the current operating power with the target power setting value carried by the load target power control instruction, so as to control the operation of the air-conditioning equipment according to the currently determined air-conditioning control method, such as controlling the compressor operating frequency of the air-conditioning equipment according to the air-conditioning control method, so as to control the operation of the air-conditioning compressor according to the temperature control requirement under the premise that the operating power of the air-conditioning equipment does not exceed the load target power, so as to quickly and accurately respond to the control demand of the power of the power load while meeting the appropriate temperature requirement set by the air-conditioning equipment.

[0065] Optionally, considering that the conventional control method of the compressor of existing air-conditioning equipment usually adopts a temperature control method, with the indoor ambient temperature as the control target, the control effect is not obvious when the set temperature is already high, and the real-time and precise control requirements of the photovoltaic storage direct and flexible system cannot be met. In this case, the embodiment of the present application obtains the load target power control instruction, and can determine the load target power and the current operating power of the air-conditioning equipment based on the load target power control instruction, so as to generate a control instruction for the air-conditioning equipment based on the current operating power of the air-conditioning equipment and the load target power, so that the air-conditioning equipment can enter a flexible control mode by responding to the control instruction, with the electric power used as the control target, so that the air-conditioning unit compressor directly controls its own operating frequency according to the target power setting value, so as to achieve rapid response and precise response to power control requirements, meet the real-time requirements of the photovoltaic storage direct and flexible system, and meet the reliability and stability requirements of the photovoltaic storage direct and flexible system.

[0066] Optionally, in the embodiment of the present application, when the current operating power is greater than the load target power, triggering the air-conditioning device to use the load target power as the control target and reducing the compressor operating frequency of the air-conditioning device may specifically include the following sub-steps:

[0067] Sub-step 1301, generating a control instruction for the air conditioning equipment based on the current operating power and the load target power;

[0068] Sub-step 1302, in response to the control instruction, triggering the air conditioning device to enter a flexible control mode;

[0069] In sub-step 1303, when the air-conditioning device enters the flexible control mode, the load target power is used as the control target to control the compressor to reduce the operating frequency until the current operating power of the air-conditioning device is not greater than the load target power.

[0070] It can be seen that after obtaining the load target power control instruction, the embodiment of the present application can compare the load target power with the current operating power of the air-conditioning equipment, so that when the current operating power of the air-conditioning equipment is greater than the load target power, the control instruction of the air-conditioning equipment can be generated based on the current operating power and the load target power. The control instruction can then be issued to the air-conditioning equipment, so that the air-conditioning equipment enters the flexible control mode. For example, after collecting the current real-time operating power of the air-conditioning unit compressor and the unit operating status, the control instruction of the air-conditioning equipment can be generated based on the current operating power and the load target power of the air-conditioning equipment according to the control processing algorithm, and the control instruction can be output to the air-conditioning compressor operation control unit of the air-conditioning equipment, so that the control instruction is transmitted to the air-conditioning compressor operation control unit as a frequency reduction control instruction, so that the air-conditioning compressor operation control unit enters the flexible control mode after receiving the control instruction, that is, enters the flexible control mode through the compressor operation control unit, and uses the load target power as the target of power consumption control according to the control instruction to control the compressor operation, that is, uses the load target power as the control target to control the compressor to reduce the operating frequency, so that the current operating power of the air-conditioning equipment is not greater than the load target power.

[0071] Optionally, in an embodiment of the present application, when the air-conditioning equipment enters the flexible control mode, the load target power is used as the control target to control the compressor to reduce the operating frequency, so that the current operating power of the air-conditioning equipment is not greater than the load target power. Specifically, it may include: when the air-conditioning equipment enters the flexible control mode, outputting a frequency reduction control instruction to the compressor operation control unit of the air-conditioning equipment; in response to the frequency reduction control instruction, reducing the compressor operating frequency through the compressor operation control unit, and collecting the real-time operating power of the air-conditioning equipment; if the real-time operating power is greater than the load target power, returning to execute the step of outputting the frequency reduction control instruction to the compressor operation control unit of the air-conditioning equipment until the real-time operating power is no greater than the load target power.

[0072] Specifically, in the embodiment of the present application, when the current operating power of the air-conditioning equipment is not greater than the load target power, a frequency reduction control instruction is output to the compressor operation control unit of the air-conditioning equipment, so that after receiving the frequency reduction control instruction, the compressor operation control unit controls the compressor to reduce the operating frequency with the load target power as the control target, that is, the operating power of the air-conditioning compressor is added as the control target, and the operating frequency of the air-conditioning compressor is reduced to reduce the operating power of the air-conditioning compressor, and the real-time operating power of the air-conditioning equipment is re-collected, so that when the real-time operating power of the air-conditioning equipment is not greater than the load target power, it is considered that the current operating power of the air-conditioning equipment is greater than the load target power, and then the operation of the air-conditioning compressor can be controlled according to the conventional control operation mode of the air-conditioning compressor according to the temperature control demand of the air-conditioning equipment, that is, the operation of the air-conditioning compressor is controlled according to the conventional control operation mode of the air-conditioning compressor to maintain the current operating frequency of the air-conditioning compressor, thereby avoiding the problem of forced power outage caused by the superposition of power peaks, and achieving rapid response and precise response to power control needs.

[0073] It can be seen that after obtaining the load target power control instruction, the embodiment of the present application can determine whether the current operating power of the air-conditioning equipment exceeds the load target power by comparing the load target power and the current operating power of the air-conditioning equipment; if the current operating power of the air-conditioning equipment exceeds the load target power, the control instruction can be output to the air-conditioning compressor operation control unit of the air-conditioning equipment, so as to transmit the control instruction to the air-conditioning compressor operation control unit as a frequency reduction control instruction, so that the air-conditioning compressor operation control unit enters the flexible control mode after receiving the control instruction, and uses the load target power as the target of power consumption control according to the control instruction, that is, with the power consumption as the control target, the air-conditioning unit compressor directly controls its own operating frequency according to the target power setting value, thereby achieving rapid power response and precise response to control requirements; and when the current operating power of the air-conditioning equipment does not exceed the load target power, the compressor operation can be controlled according to the conventional control operation mode of the air-conditioning compressor, that is, the air-conditioning compressor operation is controlled based on the indoor ambient temperature, thereby meeting the temperature control requirements.

[0074] Optionally, the air conditioning power direct control method provided in the embodiment of the present application also includes: when the real-time operating power is not greater than the load target power, determining the compressor operating frequency corresponding to the temperature control demand of the air-conditioning equipment; according to the compressor operating frequency, triggering the unit of the air-conditioning equipment to maintain the operation of the compressor.

[0075] As an example of this application, Figure 2As shown, after receiving an energy regulation instruction carrying an activation regulation flag and a target power setting value Po, the energy regulation instruction can be determined as a load target power regulation instruction, and the target power setting value Po can be used as the load target power. Subsequently, for this load target power regulation instruction, the target power setting value Po is compared with the currently actual operating power of the air-conditioning equipment, that is, the real-time operating power P of the air-conditioning unit is collected and the operating state of the air-conditioning unit is collected, so as to, based on the collected operating state of the air-conditioning unit, take the real-time operating power P of the air-conditioning unit as the current operating power of the air-conditioning equipment and compare it with the load target power. If the power value of the real-time operating power P of the air-conditioning unit exceeds the target power setting value Po, that is, Po < P, it is considered that the current operating power of the air-conditioning equipment is greater than the load target power, and the control target is the power. An adjustment instruction is output to directly reduce the frequency of the air-conditioning compressor and reduce the operating power until the power value of the real-time operating power P of the air-conditioning unit is less than or equal to the target power setting value Po, then the reduction of the operating frequency of the air-conditioning compressor is stopped, and the air-conditioning unit maintains the current operating frequency, thus solving the problem of instability such as system power outage caused by the superposition of air-conditioning power load peaks under extremely high temperature weather conditions due to the fact that the existing conventional air-conditioning regulation method finally takes the indoor environmental temperature as the control target.

[0076] Specifically, in the case where the power value of the real-time operating power P of the air-conditioning unit exceeds the target power setting value Po, that is, when it is judged that Po < P, in order to avoid the problem of forced power outage due to the superposition of peak electricity consumption, a frequency reduction control instruction can be issued as the regulation instruction for the air-conditioning equipment, so that the air-conditioning equipment reduces the operating frequency of the compressor, that is, the operating frequency of the air-conditioning compressor is reduced, so that the operating power of the air-conditioning equipment is reduced, and the real-time operating power P1 of the air-conditioning equipment is collected, so as to determine whether to continue to issue the regulation instruction to reduce the frequency of the air-conditioning compressor by judging whether the real-time operating power P1 is greater than the load target power; if the real-time operating power P1 is greater than the load target power, that is, Po < P1, then return to execute the step of issuing the frequency reduction control instruction to continue to issue the regulation instruction to reduce the frequency of the air-conditioning compressor; if the real-time operating power P1 is not greater than the load target power, that is, in the case where the power value of the real-time operating power P1 of the air-conditioning unit is less than or the target power setting value Po, then stop outputting the frequency reduction control instruction, that is, stop reducing the operating frequency of the air-conditioning unit, so that the air-conditioning unit maintains the current operating frequency, thus enabling the air-conditioning unit to maintain the operation at the load target power.

[0077] It can be seen that the above example of the present application obtains the load target power control instruction, and based on the load target power control instruction, determines the load target power and the current operating power of the air-conditioning equipment, so that when the current operating power of the air-conditioning equipment is greater than the load target power, the air-conditioning equipment is triggered to use the load target power as the control target, and reduce the operating frequency of the compressor of the air-conditioning equipment, that is, the operating power of the air-conditioning compressor is added as the control target. Compared with the existing conventional air-conditioning control method, the embodiment of the present application takes the power consumption as the control target, so that the air-conditioning equipment directly controls the operating frequency of the air-conditioning unit compressor according to the target power setting value instruction, so that the load power operation can be reduced according to the load target power set by the control instruction during the period of tight energy supply, thereby achieving rapid power response and precise response to control needs, thereby improving the stability, safety and reliability of system operation.

[0078] In a specific implementation, the air-conditioning power direct control method provided in the embodiment of the present application can be applied to an air-conditioning power direct control system, so that the air-conditioning direct control system can obtain the load target power regulation instruction, and determine the load target power and the current operating power of the air-conditioning equipment based on the load target power regulation instruction. When the current operating power is greater than the load target power, the air-conditioning equipment is triggered to use the load target power as the control target, and the compressor operating frequency of the air-conditioning equipment is reduced to reduce the power of the air-conditioning load, thereby realizing direct control of the power consumption of the air-conditioning load.

[0079] Figure 3 A structural block diagram of an air conditioning power direct control system provided in an embodiment of the present application. The air conditioning power direct control system provided in an embodiment of the present application specifically includes: a power direct control unit module 310 and an air conditioning unit 320; wherein the power direct control unit module 310 is used to obtain a load target power control instruction, and based on the load target power control instruction, determine the load target power and the current operating power of the air conditioning equipment; and, when the current operating power is greater than the load target power, trigger the air conditioning unit 320 to use the load target power as the control target and reduce the compressor operating frequency of the air conditioning equipment.

[0080] Optionally, the air-conditioning unit 320 includes a compressor operation control unit of the air-conditioning equipment; when the current operating power is greater than the load target power, the power direct control unit module 310 triggers the air-conditioning unit 320 to use the load target power as the control target to reduce the compressor operating frequency of the air-conditioning equipment. Specifically, it may include: the power direct control unit module 310 sends a control instruction of the air-conditioning equipment to the compressor operation control unit based on the current operating power and the load target power; and the compressor operation control unit responds to the control instruction to trigger the air-conditioning equipment to enter the flexible control mode.

[0081] It can be seen that the compressor operation control unit in the embodiment of the present application is used to respond to the control instruction and trigger the air-conditioning equipment to enter the flexible control mode; the flexible control mode is used to trigger the air-conditioning equipment, with the load target power as the control target, and control the compressor to reduce the operating frequency through the compressor operation control unit, so that the current operating power of the air-conditioning equipment is not greater than the load target power.

[0082] Of course, the air conditioning unit 320 may include other units of the air conditioning equipment, such as a temperature control unit, in addition to the compressor operation control unit of the air conditioning equipment, and the embodiment of the present application does not limit this. Among them, the compressor operation control unit of the air conditioning equipment refers to the air conditioning compressor control unit, and the temperature control unit refers to the air conditioning temperature control unit.

[0083] In a specific implementation, the power direct control unit module 310 can be built-in and integrated with the air conditioning unit 320 to form a power direct control air conditioning system, or it can be installed and used as a module alone, and the embodiment of the present application does not limit this. The air conditioning unit 320 includes various types of air conditioning equipment, such as household split units, multi-split units, chillers and other air conditioning equipment, and the embodiment of the present application does not limit this.

[0084] As an example of the present application, the power direct control unit module 310 described in any embodiment of the present application may include a communication interface unit, a power direct control algorithm unit, and a real-time operation power monitoring unit, so as to form a power direct control air conditioning system through the communication interface unit, the power direct control algorithm unit, the real-time operation power monitoring unit, the air conditioning compressor control unit, and the air conditioning temperature control unit, as an air conditioning power direct control system, to achieve direct control of the air conditioning load power. Specifically, considering that the temperature control unit in the traditional air conditioning unit only controls the air conditioning compressor to reduce the operating frequency or increase the compressor operating frequency according to the temperature control requirements, the air conditioning power direct control method provided by the present application can be used to add a communication interface unit, a power direct control algorithm unit, and a real-time operation power monitoring unit to the air conditioning power direct control system, and improve the air conditioning compressor operation control unit, so that the air conditioning compressor control unit can use the operating power of the air conditioning compressor as the control target, and reduce the load power operation according to the target power set by the control instruction during the period of tight energy supply, thereby improving the stability, safety and reliability of the system operation.

[0085] For example, Figure 4As shown, the air-conditioning power direct control system provided by the example of the present application includes a communication interface unit, a power direct control algorithm unit, a real-time operating power monitoring unit, an air-conditioning compressor control unit and an air-conditioning temperature control unit; wherein the communication interface unit is responsible for receiving the load target power control instructions issued by the load management platform of the photovoltaic storage direct and flexible system through a communication interface, and the communication interface method may include but is not limited to TCP communication, 4G, power line carrier, RS-485 bus / CAN bus and other communication methods; the power direct control algorithm unit is responsible for collecting the current real-time operating power of the air-conditioning unit compressor and the operating status of the unit, and based on the current real-time operating power of the air-conditioning unit compressor and the operating status of the unit, according to the control processing algorithm, outputs the control instruction to the air-conditioning compressor operation control unit, so that the air-conditioning compressor operation control unit can enter the flexible control mode according to the control instruction, take the power consumption as the control target, and directly control the air-conditioning compressor operation frequency according to the target power setting value, so as to realize the direct control of the power consumption of the air-conditioning load.

[0086] Specifically, the air-conditioning compressor operation control unit in the embodiment of the present application newly adds a flexible control mode, and enters the flexible control mode after receiving the control instruction, taking the power consumption as the control target, so that the air-conditioning unit compressor directly adjusts its own operating frequency according to the target power setting value of the system operation, thereby achieving rapid power response and precise response to control needs, thereby meeting the real-time requirements of the operation of the photovoltaic storage direct and flexible system, as well as the reliability and stability requirements of the operation of the photovoltaic storage direct and flexible system. Among them, the real-time operating power monitoring unit is responsible for feeding back the real-time power of the air-conditioning compressor. The VI curve of the compressor can be used for real-time calculation to obtain the real-time power of the air-conditioning compressor, or a separately installed power metering device can be used to realize real-time monitoring of the real-time power of the air-conditioning compressor. The power direct control algorithm unit can determine the real-time operating power of the air-conditioning equipment according to the real-time power of the air-conditioning compressor, and then send a frequency reduction control instruction according to the real-time operating power of the air-conditioning equipment and the load target power to reduce the frequency of the air-conditioning compressor and adjust the air-conditioning load to reduce the power until the real-time operating power of the air-conditioning equipment is less than or equal to the load target power, thereby building grid-load interaction, improving the electricity-friendliness of air-conditioning equipment, and improving the safety and reliability of power grid operation and load power consumption, to adapt to the high proportion of renewable energy penetration in the future.

[0087] The VI curve of the compressor refers to a curve generated by the voltage (Voltage, V) value of the compressor and the electric current (electric current) value of the compressor. According to the power calculation formula: power = voltage * current, the real-time operating power can be calculated by multiplying the voltage value by the current value.
