[0059] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0060] In one embodiment, such as Figure 1 As shown, a temperature control system control method is provided. This embodiment illustrates the application of this method to a terminal. It can be understood that this method can also be applied to a server, and to a system including both a terminal and a server, and is implemented through the interaction between the terminal and the server. In this embodiment, the method includes the following steps S102 to S106.

[0061] S102: Obtain the bus voltage of the DC power distribution system of the building where the temperature control system is located, as well as the status information of the temperature control system.

[0062] A temperature control system refers to a system capable of regulating temperature. In this embodiment, a temperature control system refers to a system capable of regulating the ambient temperature of the building where the temperature control system is located. For example, a temperature control system includes a refrigeration system and / or a heating system, such as an air conditioning system. A building where the temperature control system is located refers to a building equipped with a temperature control system. Taking an air conditioning system as an example, the building where the air conditioning system is located could be an office building, a factory, or other similar building.

[0063] The DC power distribution system can be understood as the building-side power grid where the temperature control system is located. Status information is used to represent information related to the current state of the temperature control system. For example, the status information includes system status information and environmental status information, where the system status information represents information related to the temperature control system itself, and the environmental status information represents information related to the environment in which the temperature control system is located.

[0064] S104: Based on the bus voltage and status information, determine the set temperature of the temperature control system using the prediction model of the temperature control system; wherein, the model parameters of the prediction model are related to the temperature control system and the building where the temperature control system is located.

[0065] The predictive model for the temperature control system is pre-constructed based on the system and the building in which it is located. The model parameters are related not only to the temperature control system itself but also to the building. Bus voltage and status information serve as inputs to the predictive model, and the output is the setpoint temperature of the system. The setpoint temperature represents the temperature to be controlled by the temperature control system.

[0066] S106: The temperature control system is controlled according to the set temperature. The output power of the temperature control system after being controlled is less than the output power of the temperature control system at the beginning of being controlled.

[0067] In this application, the operating state of the temperature control system is controlled with a set temperature as the target, so that the output power of the temperature control system after being controlled is lower than the output power at the beginning of the control, thereby achieving flexible operation and reducing power consumption. Here, "temperature system under control" refers to controlling the temperature control system using the temperature control system control method provided in this application embodiment. The fact that the output power of the temperature control system after being controlled is lower than the output power at the beginning of the control indicates that the output power of the temperature control system has been reduced after being controlled, achieving the goal of low power consumption and low carbon emissions.

[0068] The aforementioned temperature control system control method acquires the bus voltage of the DC power distribution system of the building where the temperature control system is located, as well as the status information of the temperature control system. Based on the bus voltage and status information, the set temperature of the temperature control system is determined using a predictive model. The model parameters of the predictive model are related to both the temperature control system and the building where it is located. The temperature control system is controlled according to the set temperature, and the output power of the temperature control system after being controlled is less than the output power at the start of control. This method uses the bus voltage of the DC power distribution system of the building where the temperature control system is located as the control basis for the flexible operation of the temperature control system. It can more intuitively reflect the relationship between renewable energy generation and electrical charge consumption in the building-side power grid. Furthermore, by determining the set temperature of the temperature control system through a pre-constructed predictive model, and changing the set temperature, the output power of the temperature control system is changed, achieving flexible operation of the temperature control system, reducing power consumption, and achieving the goal of low power consumption and low carbon emissions.

[0069] In one embodiment, such as Figure 2 As shown, step S104, based on the bus voltage and status information, uses the prediction model of the temperature control system to determine the set temperature of the temperature control system, including the following steps S202 and S204.

[0070] S202: Determine the power coefficient of the temperature control system based on the bus voltage.

[0071] The power factor is used to guide the control and adjustment of the set temperature of a temperature control system. Alternatively, the power factor can be understood as the degree to which the output power of the temperature control system is adjusted. The larger the power factor, the smaller the reduction in the output power of the temperature control system; the smaller the power factor, the greater the reduction in the output power of the temperature control system.

[0072] S204: Based on the power coefficient and status information, the set temperature of the temperature control system is determined using the predictive model of the temperature control system.

[0073] For example, the target output power of the temperature control system is determined according to the power coefficient and the rated power of the temperature control system, and the set temperature of the temperature control system is determined according to the target output power of the temperature control system by using the prediction model of the temperature control system. For example, the product of the power coefficient and the rated power of the temperature control coefficient is determined as the target output power of the temperature control system. The rated power of the temperature control system can be the total rated power of all temperature control devices in the temperature control system, or the total rated power of the temperature control systems in the temperature control system in the on state, which can be set according to the actual application scene, which is not limited here.

[0074] In the application, after the terminal determines the set temperature of the temperature control system according to the power coefficient and the state information by using the prediction model, the set temperature can be used as the temperature that needs to be set for each temperature control device (or each temperature control device currently in the running state) in the temperature control system, and the temperature control device in the temperature control system is controlled to flexibly run, so as to achieve the purpose of reducing power consumption.

[0075] The above-mentioned temperature control system control method determines the power coefficient of the temperature control system according to the bus voltage, and determines the set temperature of the temperature control system according to the power coefficient and the state information by using the prediction model of the temperature control system. This method can dynamically adjust the power coefficient according to the change of the bus voltage, dynamically adjust the set temperature of the temperature control system according to the power coefficient, and further reduce the power consumption by changing the set temperature of the temperature control system. This method not only improves the energy efficiency and temperature control accuracy of the temperature control system, but also improves the reliability and user experience of the system, and brings multiple advantages of economic benefits and environmental friendliness.

[0076] In one embodiment, step S202, determining the power coefficient of the temperature control system according to the bus voltage, comprises the step of determining the power coefficient of the temperature control system according to the bus voltage and a preset voltage coefficient relationship library.

[0077] The voltage coefficient relationship library is pre-established, and the voltage coefficient relationship library includes a plurality of voltage coefficient relationships. The voltage coefficient relationship in the voltage coefficient relationship library is used to represent the mapping relationship between the bus voltage and the power coefficient. For example, the voltage coefficient relationship is used to represent the mapping relationship between the voltage interval corresponding to the bus voltage and the power coefficient. The bus voltage and the power coefficient are positively correlated. The larger the bus voltage, the larger the corresponding power coefficient; the smaller the bus voltage, the smaller the corresponding power coefficient.

[0078] In the application, the terminal can determine the voltage interval in which the bus voltage is located, and determine the corresponding power coefficient according to the voltage interval. In this way, the set temperature of the temperature control system can be determined according to the power coefficient, so as to control the running state of the temperature control system according to the set temperature, realize the regulation and control of the output power of the temperature control system, and achieve the purpose of reducing power consumption.

[0079] In one embodiment, the voltage coefficient relationship library includes a first voltage coefficient relationship and a second voltage coefficient relationship, the first voltage coefficient relationship is used to represent the association between the bus voltage in the first voltage interval and the first power coefficient, and the second voltage coefficient relationship is used to represent the association between the bus voltage in the second voltage interval and the second power coefficient.

[0080] As shown in Figure 3 The above steps of determining the power coefficient of the temperature control system according to the bus voltage and the preset voltage coefficient relationship library include the following steps S302 to S306.

[0081] S302: Determine the voltage interval corresponding to the bus voltage according to the voltage coefficient relationship library, the voltage interval including a first voltage interval and a second voltage interval.

[0082] The first voltage interval and the second voltage interval are different. In application, the first voltage interval and the second voltage interval can be defined by at least one voltage threshold.

[0083] S304: In the case that the bus voltage is in the first voltage interval, determine the power coefficient corresponding to the bus voltage as the first power coefficient.

[0084] For example, the bus voltage in the first voltage interval means that the bus voltage is less than the first voltage threshold and the bus voltage is greater than or equal to the second voltage threshold. The first voltage threshold is greater than or equal to the second voltage threshold. The first voltage threshold, the second voltage threshold and the first power coefficient are all preset, which can be determined according to the actual scene or test, and are not limited here. For example, taking an air conditioning system as an example, the first voltage threshold is 770V, the second voltage threshold is 730V, and the first power coefficient is 0.75, that is, in the case that the bus voltage is less than 770V and the bus voltage is greater than or equal to 730V, the power coefficient corresponding to the bus voltage is determined as 0.75.

[0085] S306: In the case that the bus voltage is in the second voltage interval, determine the power coefficient corresponding to the bus voltage as the second power coefficient; wherein the minimum value of the first voltage interval is greater than or equal to the maximum value of the second voltage interval, and the second power coefficient is less than the first power coefficient.

[0086] For example, the bus voltage is in the second voltage interval, indicating that the bus voltage is less than the third voltage threshold and the bus voltage is greater than or equal to the fourth voltage threshold. The third voltage threshold is greater than or equal to the fourth voltage threshold, and the third voltage threshold is less than or equal to the second voltage threshold. The third voltage threshold, the fourth voltage threshold and the second power coefficient are all preset, which can be determined according to actual scene or test, and will not be limited here. For example, taking the air conditioning system as an example, the third voltage threshold is 730V, the fourth voltage threshold is 0V, and the second power coefficient is 0.5, that is, in the case of bus voltage less than 730V, the power coefficient corresponding to the bus voltage is determined to be 0.5.

[0087] It should be noted that in the case that the bus voltage is not in the first voltage interval and the second voltage interval, it indicates that the temperature control system does not need to be regulated, at this time the energy consumption of the temperature control system is low, meeting the demand of low power consumption and low carbon, without intervention and regulation.

[0088] The above-mentioned temperature control system control method determines the voltage interval corresponding to the bus voltage according to the voltage coefficient relationship library, and determines the power coefficient corresponding to the bus voltage as the first power coefficient in the case that the bus voltage is in the first voltage interval, and determines the power coefficient corresponding to the bus voltage as the second power coefficient in the case that the bus voltage is in the second voltage interval; wherein the minimum value of the first voltage interval is greater than or equal to the maximum value of the second voltage interval, and the second power coefficient is less than the first power coefficient. This method can achieve more precise power control by dividing the bus voltage into different intervals and setting different power coefficients for each interval. This segmented control method can better adapt to the system demand under different voltage conditions. When the bus voltage changes in different intervals, the system can automatically adjust the power coefficient to ensure that the system always operates in the optimal state, not only improving the energy efficiency and stability of the system, but also prolonging the service life of the equipment, improving the comfort of users, bringing significant economic benefits and environmental friendliness, reducing carbon emissions, and meeting the requirements of sustainable development.

[0089] In one embodiment, the state information includes system state information and environment state information. The system state information is used to represent information related to the running state of the temperature control system itself. For example, the system state information includes device state information of each temperature control device in the temperature control system, and the device state information is used to represent the running state of the temperature control device. The environment state information is used to represent information related to the environment in which the temperature control system is located. For example, the environment state information includes at least one of indoor environment temperature and outdoor environment temperature.

[0090] As shown in Figure 4 Step S204, according to the power coefficient and the state information, the set temperature of the temperature control system is determined by using the prediction model of the temperature control system, including the following steps S402 to S406.

[0091] S402: Determine all target temperature control devices in the on state in the temperature control system according to the running state information of each temperature control device in the system state information.

[0092] The target temperature control device can be one or more in number, and refers to a temperature control device in the on state in the temperature control system.

[0093] S404: Determine the target output power of each target temperature control device according to the rated power and power coefficient of each target temperature control device.

[0094] For example, the product of the rated power and the power coefficient of each target temperature control device is determined as the target output power of each target temperature control device. The rated power of the target temperature control device can be pre-stored or real-time acquired, which is not limited here.

[0095] S406: Determine the device set temperature of each target temperature control device according to the target output power and the environmental state information by using a prediction model, so as to control the target temperature control device in the temperature control system according to the device set temperature.

[0096] The set temperature of the temperature control system includes the device set temperature of each target temperature control device. The target output power and the environmental state information are input to the prediction model, and the output of the prediction model is the device set temperature of the target temperature control device.

[0097] For example, the prediction model is expressed by the following formula:

[0098] (1)

[0099] (2)

[0100] Wherein, is the room heat capacity; , is the formula fitting coefficient; a is the temperature difference heat gain coefficient; b is the heat capacity heat gain coefficient; P gen is the indoor internal heat source power; COP is the air conditioning comprehensive coefficient; P AC represents the target output power; T out represents the outdoor environment temperature; T in,0 represents the indoor environment temperature at the beginning of the control; T set represents the indoor environment temperature after τ time of the control; τ represents the control duration or response duration, which is a pre-set value, for example, the value of τ is in the range of 1-5 min; T AC represents the set temperature.

[0101] The formula fitting coefficient in the formula is , is a time variable related to the thermal inertia of the room, obtained by fitting the response experiment.

[0102] In the application, the terminal can input the target output power P AC , the outdoor and indoor ambient temperatures, and the indoor ambient temperature after the controlled start time into the prediction model to determine the device set temperature of the target temperature control device, respectively, so that the target temperature control device in the temperature control system can be controlled according to the device set temperature, and the target temperature control device is adjusted to a flexible operation state, thereby reducing the output power and achieving low power consumption and low carbon.

[0103] The above temperature control system control method determines all target temperature control devices in the temperature control system in the on state according to the operation state information of each temperature control device in the system state information, determines the target output power of each target temperature control device according to the rated power and power coefficient of each target temperature control device, and determines the device set temperature of the target temperature control device according to the target output power and the environmental state information, so as to control the target temperature control device in the temperature control system according to the device set temperature. This method determines the target output power of each target temperature control device according to its rated power and current power coefficient, can realize individual adjustment of each device, ensures that each device can operate in its optimal state, dynamically adjusts the set temperature of each target temperature control device in combination with the environmental state information, can quickly respond to environmental changes, maintains the stability and comfort of indoor temperature, and can achieve flexible operation control of each target temperature control device, improves the accuracy of temperature control, and improves the energy efficiency and stability of the system, and achieves the purpose of low power consumption and low carbon.

[0104] In one embodiment, as shown in Figure 5 The temperature control system control method further includes the following steps S502 to S506.

[0105] S502: Obtain the configuration information of the temperature control system and the building information of the building where the temperature control system is located.

[0106] S504: Determine the model parameters of the prediction model according to the configuration information and the building information.

[0107] S506: Construct the prediction model of the temperature control system according to the model parameters, and the prediction model is used to determine the set temperature of the temperature control system according to the bus voltage and the state information.

[0108] The configuration information is used to represent information related to the configuration of the temperature control system itself, for example, the type, model, service life, position in the building, rated power, etc. of the temperature control device in the temperature control system, which is not limited herein. The building information is used to represent the basic information of the building where the temperature control system is located, for example, the volume, number of floors, floor height, number of rooms, room area, etc. of the building where the temperature control system is located, which is not limited herein. The configuration information and the building information are intended to be used to fit the model parameters of the prediction model. The model parameters are determined according to the configuration information and the building information of the temperature control system. Different temperature control systems correspond to different model parameters of the prediction model.

[0109] In the application, the room heat capacity, the formula fitting coefficient, the temperature difference heat gain coefficient, the heat capacity heat gain coefficient, and the air conditioner comprehensive coefficient can be fitted according to the configuration information and the building information, and a prediction model is established to associate the time P, the temperature T, and the time τ. Among them, the indoor heat source power, the target output power, the outdoor environment temperature, the indoor environment temperature, and the indoor environment temperature after the controlled start time τ can be obtained by real-time monitoring and calculation processing through the detection device, wherein the specific calculation process of the target output power can be referred to the foregoing introduction, which will not be repeated here.

[0110] The above-mentioned temperature control system control method, obtains the configuration information of the temperature control system and the building information of the building where the temperature control system is located, determines the model parameters of the prediction model according to the configuration information and the building information, constructs the prediction model of the temperature control system according to the model parameters, and the prediction model is used to determine the set temperature of the temperature control system according to the bus voltage and the state information, so that the set temperature of the temperature control system can be predicted according to the prediction model, and then the operation of the temperature control system can be controlled according to the set temperature, so as to achieve the purpose of controlling the flexible operation of the temperature control system, so as to reduce the power consumption.

[0111] In one embodiment, as shown in Figure 6 The temperature control system control method further includes the following steps S602 to S606.

[0112] S602: Obtain the indoor environment temperature of each temperature control device after being controlled in the temperature control system.

[0113] S604: Determine the abnormal temperature control device from each temperature control device according to the indoor environment temperature of each temperature control device after being controlled.

[0114] S606: Stop controlling the abnormal temperature control device.

[0115] For example, for each controlled temperature control device, it is determined whether the indoor environment temperature after the temperature control device is controlled exceeds the preset temperature range. If yes, the temperature control device is determined as an abnormal temperature control device, and the control of the abnormal temperature control device is stopped. If no, the temperature control device is determined as a normal temperature control device, and the normal temperature control device continues to be controlled to run flexibly. The preset temperature range is pre-set and is used to represent the indoor comfortable temperature range. For example, the preset temperature range can be [22℃, 28℃].

[0116] The above-mentioned temperature control system control method obtains the indoor environment temperature after at least part of the temperature control devices in the temperature control system are controlled, determines the abnormal temperature control device from the at least part of the temperature control devices according to the indoor environment temperature after each temperature control device is controlled, and stops controlling the abnormal temperature control device. The method realizes the identification of the abnormal temperature control device by monitoring the indoor environment temperature after being controlled in real time. That is, the indoor environment temperature after the abnormal temperature control device is controlled does not meet the indoor environment temperature comfort requirement. In this case, the control of the abnormal temperature control device is stopped, the indoor environment temperature comfort requirement is preferentially met, and the user experience is improved.

[0117] In one embodiment, as shown in Figures 7 to 11 A temperature control system control method is provided. Taking an air conditioning system as an example, the air conditioning system includes multiple on-line air conditioners. The method includes the following steps S702 to S712.

[0118] S702: Obtain the bus voltage of the direct current power distribution system of the building where the air conditioning system is located, and the system state information and the environment state information of the air conditioning system.

[0119] The system state information includes the rated power of the air conditioner and the state information of the air conditioner. The environment state information includes the indoor environment temperature, the outdoor environment temperature, and the indoor environment temperature after being controlled for a time τ.

[0120] S704: Determine the power coefficient of the air conditioning system according to the bus voltage and the preset voltage coefficient relationship library.

[0121] As shown in Figure 8 and Figure 10 In the direct current voltage droop control mode, the relationship between the output power of the power supply of the grid, the energy storage, and the photovoltaic in the light storage direct current flexible power distribution system and the change of the bus voltage is:

[0122] Taking a building DC power distribution system with a rated bus voltage of 375V as an example, when photovoltaic power generation gradually increases the power generation power, the bus voltage decreases from 415V to 390V, at this time the photovoltaic has reached the maximum output, and the current energy storage charges at a constant power. When the photovoltaic power generation is insufficient to support system power consumption, the bus voltage begins to drop, and the energy storage charging power decreases with the voltage drop until 380V power is 0, and then it is discharged and rises to the maximum at 375V. When the power further increases and neither photovoltaic nor energy storage is sufficient, the power grid begins to output power, and the voltage drops below 375V, and the power grid takes power at a maximum output when the voltage is 315V.

[0123] For a DC power distribution system with a rated voltage of 750V, when the bus voltage reaches 770V and above, it indicates that solar photovoltaic is sufficient, and the system will run completely with solar power generation; when the bus voltage is in the interval of 770~730V, it is mainly dominated by energy storage to supply power to the system; when the bus voltage is lower than 730V, it means that the distributed power output is insufficient, and the system will completely rely on municipal power.

[0124] Based on the above, when the bus voltage is 770V and above, the air conditioner runs normally and does not need to be controlled; when the bus voltage is in the interval of 770~730V, the air conditioner power is reduced, and the definition is reduced to 75% of the rated power (or ensure the current lower power value), that is, the power coefficient is 0.75; when the bus voltage is lower than 730V, the air conditioner power is further reduced to 50% of the rated power (or ensure the current lower power value), that is, the power coefficient is 0.5.

[0125] In the application, the voltage signal of the DC power distribution system can be collected in real time, and the interval in which the voltage signal is located can be determined, and a corresponding adjustment signal can be generated. The voltage signal includes the bus voltage, and the adjustment signal includes the power coefficient.

[0126] S706: Determine all target air conditioners in the on state in the air conditioning system according to the running state information of each air conditioner in the system state information.

[0127] S708: Determine the target output power of each target air conditioner according to the rated power and the power coefficient of each target air conditioner.

[0128] In the application, the product of the rated power and the power coefficient of the target air conditioner can be determined as the target output power P AC .

[0129] S710: Determine the device set temperature of each target air conditioner according to each target output power and environmental state information by using a prediction model.

[0130] In the application, the target output power P AC, the indoor environment temperature T out , the indoor environment temperature T in,0 , the indoor environment temperature T , the indoor environment temperature T set .

[0131] S712: Control each target device in the air conditioning system according to the corresponding device set temperature.

[0132] The temperature control system control method determines the dominant situation of different power outputs of the direct current bus voltage, determines the target output power of each target air conditioner in the air conditioning system in the open state, establishes an air conditioning power prediction model, and solves the set temperature of each target air conditioner under the target output power. The purpose of flexible operation is achieved by changing the set temperature of the target air conditioner. The method is based on the building direct current distribution system bus voltage to control the flexible operation of the multi-connected air conditioner. The mechanism is clear and the principle is simple. High bus voltage means that renewable energy is sufficient, and the air conditioner should reasonably increase the power and indoor cold storage; low bus voltage means that the power supply is tight, and the air conditioner should reasonably reduce the power and use indoor cold storage to offset the cold load.

[0133] The method takes a variable frequency multi-connected air conditioner as an object, proposes an air conditioner flexible operation mechanism based on the bus voltage of the building direct current distribution system, and verifies the method effect and feasibility through engineering practice. In the light storage direct flexible building applying the bus voltage droop control strategy, the output modes of solar photovoltaic, energy storage battery and power grid respectively dominated correspond to different direct current bus voltages, so that the current renewable energy utilization can be judged by the high and low voltage. The flexible operation method proposed in the application utilizes the regulation of the change of the direct current bus voltage, and uses the high and low voltage value as a control signal to guide the air conditioning power control. Through the power prediction model, the air conditioning operation state, indoor and outdoor environment temperature, air conditioning power data are collected and used as model output, the set temperature of the air conditioner under the target power can be calculated, and the set temperature of the device is changed to realize the power control effect.

[0134] When the bus voltage is 770V or above, the air conditioner operates normally and does not need to be controlled; when the bus voltage is in the range of 770~730V, the air conditioner power should be reduced, and the process is simplified by defining the reduction to 75% rated power (or ensuring the current lower power value); when the bus voltage is lower than 730V, the air conditioner power should be further reduced to 50% rated power (or ensure the current lower power value).

[0135] In order to evaluate the flexible adjustment effect of the equipment after receiving the response instruction, the air conditioner flexible operation engineering verification is carried out. Figure 11The process of air conditioning power after receiving the response instruction to reach the response target is shown. A is the initial response time, at which the system monitors the change of the DC bus and starts to respond to the control of the air conditioner; B is the response action time, at which the power starts to change, indicating that the device has started to respond flexibly; C is the response target time, at which the device power reaches the flexible response target.

[0136] Response action time R DR1 The time length from the initial response time to the response action time, indicating the time interval from receiving the instruction to the action of the control system, that is, R DR1 =t B -t A ; the response target time R DR2 The time length from the initial response time to the response target time, indicating the time required for the entire flexible response, that is, R DR2 =t C -t A ; the difference between the power at the response target time and the power at the initial response time is the response power ΔP DR , the downward adjustment (power reduction) is defined as a positive value, that is, ΔP DR =P A -P C .

[0137] The engineering verification of the flexible operation method of the multi-split air conditioner is selected in an office building. The summer climate has the characteristics of high temperature and high humidity, so the air conditioning refrigeration power is large, the operation time is long, and it also has greater demand response potential. The engineering verification area is the office area of a 2-story building, with a total cooling area of 1400m2. The multi-split air conditioner used in the laboratory is a certain direct-current variable frequency multi-split air conditioner with a rated voltage of 750V and a rated electric power of 10.5kW under refrigeration conditions. The verification experiment is selected in the daytime in June in summer, with outdoor temperature in the range of 24~34℃ and air relative humidity of about 65%~85%. At this time, it is in the air conditioning season of the summer hot and winter cold region. During the verification process, the five multi-split air conditioners of the office building are kept in the full open state, and the flexible operation time period is the cooling season. According to the experiment and actual measurement, the relationship among the power P, the temperature T, and the time parameter τ is:

[0138] (3)

[0139] (4)

[0140] The operation and control of the air conditioning body during the flexible operation are as follows Figures 12 to 19As shown by the results, in the building automation system, it takes 5 minutes from receiving the response instruction to issuing the control instruction, which includes 5 steps of voltage data and air conditioning operation parameter collection and storage, database calling, program control amount calculation, control instruction issuing through API interface, and device communication transmission control variable. This part of time delay is inevitable on the existing control architecture. The response compliance duration R DR2 is 6-8 minutes, and the response power AP DR is 16.68-29.00 kW.

[0141] R DR2 R DR1 It can be seen that the time for the multi-connected air conditioner to achieve the power reduction effect after adjusting the indoor set temperature is 1-3 minutes, and the adjustment rate of the multi-connected air conditioner is 8.34-22.10 kW / min. Taking June 13th as an example, Figure 12 a in FIG. 6a, Figure 13 a in FIG. 6b respectively show the bus voltage and the power change of the five air conditioners, Figure 12 b in FIG. 6c, and Figure 13 b in FIG. 6d respectively show the air conditioning set temperature change, Figure 14 and Figure 15 the indoor temperature change of each node in the flexible operation process of the air conditioner is shown in FIG. 6e. Taking June 20th as an example, Figure 16 a in FIG. 7a, Figure 17 a in FIG. 7b respectively show the bus voltage and the power change of the five air conditioners, Figure 16 b in FIG. 7c, and Figure 17 b in FIG. 7d respectively show the air conditioning set temperature change, Figure 18 and Figure 19 the indoor temperature change of each node in the flexible operation process of the air conditioner is shown in FIG. 7e. As can be seen from Figures 12 to 19 , the indoor temperature of the areas covered by air conditioners 1-4 is between 22-28℃, which can basically meet the indoor thermal comfort demand.
