[0001] The present invention relates to the technical field of power system control, and in particular to an air conditioning load balancing method, device, equipment and storage medium. Background Art

[0003] In the related technologies, traditional control of air-conditioning load mostly relies on communication networks, which are implemented by means of data collection and uploading, control reference point calculation and one-time instruction issuance. The communication capabilities of the actual application scenarios are not considered, and it is impossible to effectively deal with the impact of random state changes that may occur during the regulation process on the control strategy, making it difficult for the control effect to achieve the expected result. In addition, the traditional method only regulates the air-conditioning load, but does not maintain the load balance, resulting in the regulation being only temporary.

[0029] Method Embodiment

[0030] According to an embodiment of the present invention, an air conditioning load balancing method is provided. The method is deployed on a cloud platform. The cloud platform is convenient for integrating resources of a large number of decentralized air conditioning devices, and provides a practical and effective technical reference for centralized control of air conditioning load balancing. The cloud platform can serve as an important medium for connecting the power grid and the air conditioning load. On the one hand, it monitors the operating status of each air conditioning device, and on the other hand, it receives control requirements from the power business system to achieve air conditioning load balancing. Figure 1is a flow chart of the air conditioning load balancing method according to an embodiment of the present invention. Figure 1 As shown, the air conditioning load balancing method according to an embodiment of the present invention specifically includes:

[0031] In step S110, receiving the load control amount to be reduced or increased specifically includes:

[0032] The load demand is predicted through the machine learning algorithm in the cloud platform, and the load control amount that needs to be reduced or increased is automatically generated based on the load demand.

[0033] In step S120, the adjustable capacity of each air conditioner is obtained, and the adjustable time of each air conditioner is calculated in real time. Based on the descending order of the adjustable time, the currently turned-on air conditioners are sorted to form an on group, and the currently turned-off air conditioners are sorted to form a turned-off group, which specifically includes:

[0034] For each air-conditioning device, the air-conditioning load controls the operating state according to the relationship between the current room temperature and the set temperature. During the operation of the device, the indoor temperature is collected at a fixed frequency to determine whether it is within the upper and lower thresholds allowed by the set temperature, that is, the minimum and maximum temperatures that the user is satisfied with. If the room temperature reaches the high threshold, the device starts working and the room temperature decreases. If the room temperature reaches the low threshold, the device stops working and the room temperature rises. The relationship is expressed as shown in Formula 2:

[0035]

[0036] Where δ represents the temperature control dead zone, T set Indicates the set temperature, T l Indicates the low threshold, T h Represents the high threshold value. According to Formula 2, the high and low threshold values ​​can be calculated in advance according to the ideal set temperature;

[0037] Figure 2 Schematic diagram of a single device operation cycle of an embodiment of the present invention. Figure 2 As shown, it shows the temperature change cycle under the control of air conditioning equipment, T room (t) represents the room temperature. When the air conditioner is turned on, the rated load power P will increase. When the air conditioner is turned off, the rated load power will decrease immediately.

[0038] The rated load power of each air-conditioning device is obtained as the corresponding adjustable capacity. When the air-conditioning device is turned on, the adjustable capacity is the amount by which the power can be adjusted downward. When the air-conditioning device is turned off, the adjustable capacity is the amount by which the power can be adjusted downward. It should be noted that the rated load power values ​​of the air-conditioning devices are not consistent, but for each air-conditioning device, it is assumed that the value will not change.

[0039] Based on the duration calculation formula derived from the single air conditioner ETP physical model, the single air conditioner ETP physical model uses equivalent parameters of heat capacity and thermal resistance to establish the relationship between power consumption and energy efficiency ratio, ambient temperature and time, as shown in Formula 3. Formula 3 is a differential expression:

[0040]

[0041] Among them, T out (t) represents the outdoor temperature, C represents the equivalent heat capacity of the room, R represents the equivalent thermal resistance of the room, and Q represents the cooling power of the air-conditioning load. Q is determined by its energy efficiency ratio η and the rated load power P rated After multiplication, s(t) represents the switch state. A value of 1 indicates that the air conditioner is on, and a value of 0 indicates that the air conditioner is off. Δt represents a sufficiently small time lag, which represents simulation time compensation in the simulation environment.

[0042] Solving formula 3 can deduce the on-cycle and off-cycle of the air conditioning load. The first formula in formula 3 can be regarded as the derivative of the function y with respect to the time variable. The mathematical method is used to solve the differential equation. When T room (t) = T l Time t off , when T room (t) = T h Time t on , the deduced result is shown in formula 4:

[0043]

[0044] Furthermore, we can get the time it takes for the room temperature to change from any two temperatures when the air conditioner is turned on and off. When the air conditioner is turned on, it is t on (T room1 ,T room2 ), in the closed state, t off (T room1 ,T room2 ), it should be noted that T room1 and T room2 All satisfy the constraint that the temperature threshold range cannot be exceeded;

[0045] Replacing the time amount in Formula 4 can get the form of Formula 1, and use Formula 1 to calculate the adjustable time of each air conditioner. The adjustable time is the time that can be maintained in the on or off state after adjustment:

[0046]

[0047] Among them, t on (T room1 ,T room2) indicates that the room temperature of the air conditioner changes from T room1 Change to T room2 The adjustable time, t off (T room1 ,T room2 ) indicates that the room temperature of the air conditioner changes from T room1 Change to T room2 The adjustable time, C represents the equivalent heat capacity of the room, R represents the equivalent thermal resistance of the room, Q represents the cooling power of the air conditioning load, T out (t) represents the outdoor temperature;

[0048] If the air conditioner is turned on after adjustment, use t on (T room1 ,T room2 ) calculates the time between the current room temperature and the low threshold temperature as the adjustable time; if the air conditioner is in the off state after adjustment, use t off (T room1 ,T room2 ) calculates the time between the current room temperature and the high threshold temperature as the adjustable time.

[0049] Figure 3 Schematic diagram of a single device switch control response according to an embodiment of the present invention. Figure 3 As shown in the figure, the response of switching from the on state to the off state is shown. During the period 0-t1, the air conditioning load is within the normal working range, and the room temperature is [T l ,T h ] changes periodically, and the air conditioning equipment is switched off in real time at time t1, which should have been kept on until the lower threshold T l , but after the shutdown control is implemented, the rated load power is P rated The time that can be reduced can be calculated according to Formula 1. After the air conditioning equipment is regulated, it is in the off state, so t off (T room1 ,T room2 ) Calculate the adjustable time, that is, the time that the closed state can be maintained;

[0050] For air-conditioning equipment, if its adjustable time is longer, it means that the time until the next temperature threshold is longer. Air-conditioning equipment with a long adjustable time is preferred, which can ensure the stability of the load to a large extent. Therefore, the embodiment of the present invention uses the descending order of adjustable time as the sorting basis;

[0051] Formula 1 is used to calculate the adjustable time of each air-conditioning device in the on group and the off group at the current moment in real time. The sorted on group and the off group are shown in Formula 5:

[0052]

[0053] in, It represents the opening group sorted by adjustable time at time t, Indicates turning on the i-th ranked air conditioner in the group. represents the shutdown group sorted by adjustable time at time t, Indicates the air conditioning equipment with the ith ranking in the shutdown group;

[0054] As time changes, the sum of the number of air-conditioning equipment in the two groups will not change. For the adjustable potential of the air-conditioning load group, the potential for load downward adjustment is the sum of all adjustable capacities in the open group, and the potential for load upward adjustment is the sum of all adjustable capacities in the closed group.

[0055] In step S130, the initial load regulation is performed. If the load needs to be reduced, the air conditioning devices are selected from the on group in sequence to be turned off. If the load needs to be increased, the air conditioning devices are selected from the off group in sequence to be turned on until the sum of the adjustable capacities of the selected devices is greater than or equal to the load regulation amount. The on group and the off group are updated and maintained, specifically including:

[0056] If the load needs to be reduced, the air-conditioning equipment that needs to be turned off will be removed from the on group, the adjustable time will be updated and calculated, and the corresponding position in the descending order of the off group will be added; if the load needs to be increased, the air-conditioning equipment that needs to be turned on will be removed from the off group, the adjustable time will be updated and calculated, and the corresponding position in the descending order of the on group will be added;

[0057] That is, when receiving an instruction to increase the load, the air conditioner with the highest ranking in the shutdown group is turned on first, and when the load needs to be reduced, the air conditioner with the highest ranking in the opening group is turned off first; the calculation method for adjusting the number of air conditioners to be turned on or off is shown in Formula 6:

[0058]

[0059] Among them, P rated,i represents the adjustable capacity corresponding to air conditioning equipment i, that is, the rated load power, ΔP dec Indicates the load control amount that needs to be reduced, ΔP inc Indicates the amount of load control that needs to be increased, nclose indicates the number of devices that need to be switched off, and nopen indicates the number of devices that need to be switched on.

[0060] In step S140, the status and room temperature of the two groups of air conditioners are monitored in real time. When the room temperature of the air conditioner reaches a threshold, the status of the air conditioner is switched and the energy block suppression method is used to smooth the power, which specifically includes:

[0061] The total load of the air conditioning equipment cluster after initial regulation is taken as the total energy block;

[0062] If the room temperature of the air-conditioning equipment in the closed group reaches the high threshold, the adjustable capacity of the air-conditioning equipment is obtained as the energy block to be allocated, and some air-conditioning equipment is selected from the open group to be closed, and the room temperature of the selected air-conditioning equipment is lower than the set temperature, until the sum of the adjustable capacities of the selected air-conditioning equipment is greater than or equal to the energy block to be allocated, and the air-conditioning equipment that reaches the high threshold is turned on to stabilize the total amount of energy blocks;

[0063] If the room temperature of the air-conditioning equipment in the on group reaches the low threshold, the adjustable capacity of the air-conditioning equipment is obtained as the energy block to be released, and some air-conditioning equipment is selected from the off group to be turned on, and the room temperature of the selected air-conditioning equipment is higher than the set temperature, until the sum of the adjustable capacities of the selected air-conditioning equipment is greater than or equal to the energy block to be released, and the air-conditioning equipment that reaches the low threshold is turned off to stabilize the total amount of energy blocks;

[0064] Since the initial control has already adjusted the air conditioning load to the target value, the purpose of power leveling is to stabilize the load. Therefore, when choosing to turn on or off the air conditioning equipment, the premise is to try to meet the balance. That is, the released energy needs to have a similar amount of adjustable capacity, and vice versa.

[0065] Considering that the transfer of energy blocks may affect the heating of residents, it is stipulated that the room temperature of the air-conditioning equipment released in the opening group needs to be lower than the set temperature T set , the room temperature of the air conditioner where the energy block is obtained in the shutdown group must be higher than the set temperature T set , as a constraint for choosing whether to turn the air conditioner on or off.

[0066] During the state switching process, the open group and the closed group are updated and maintained in real time.

[0067] The above technical solutions of the embodiments of the present invention are illustrated with reference to the following drawings.

[0068] Figure 4 Schematic diagram of the energy block suppression method of an embodiment of the present invention, such as Figure 4 As shown in the figure, the difference between the traditional energy use mode and the energy block energy use mode is shown. For the convenience of explanation, the adjustable capacity between different devices is set to the same size. After the initial adjustment, the total load of the air conditioning equipment cluster is 3 units. Figure 4 The middle longitudinal dimension is the height H of the energy block corresponding to the device EB , corresponding to the rated load power, the sum of the longitudinal dimension is the total amount of energy blocks, and the horizontal dimension is the single energy consumption time of the load;

[0069] Before time t1, the start-up group is {device 1, device 3, device 5}. At time t1, the room temperature of device 2 reaches the high threshold and needs to be turned on. The cloud platform allocates the energy block of device 3 to device 2, and device 3 is turned off and device 2 is turned on.

[0070] At time t2, the room temperature of device 4 reaches the high threshold and needs to be turned on. At this time, the cloud platform turns off device 5 to release its energy block and allocates it to device 4. Device 5 is turned off and device 4 is turned on.

[0071] At time t3, the room temperature of device 1 reaches the low threshold and needs to be shut down. At this time, device 3 is selected from the shutdown group {device 3, device 5}, and the energy block released by device 1 is allocated to device 3. Device 1 is shut down and device 3 is turned on.

[0072] At time t4, the room temperature of device 2 reaches a low threshold and needs to be shut down. The energy block released by device 2 is allocated to device 5, and device 2 is shut down and device 5 is turned on.

[0073] Subsequent power leveling is carried out in this way. Theoretically, the total load can be stabilized at 3P rated .

[0074] Figure 5 Schematic diagram of the air conditioning load balancing framework of the embodiment of the present invention. Figure 5 As shown in the figure, the complete process of implementing air conditioning load balancing on the cloud platform is demonstrated.

[0075] The method further comprises:

[0076] Controlling the air conditioning load will change the user's electricity usage habits. Preferably, the cloud platform can calculate the user's electricity comfort. In order to quantitatively describe the user's satisfaction with the heating temperature, the temperature utility evaluation index is introduced, as shown in Formula 7:

[0077]

[0078] Among them, T room,i Indicates the actual temperature value in the room of air-conditioning equipment i, E(T room,i ) represents the indoor temperature utility of air-conditioning equipment i, λ represents the control coefficient of different equipments, when T l ≤T room,i <T set When T room,i =T set When T set <T room,i ≤T h When T room,i <T l or T room,i >Th When , the temperature utility is negative;

[0079] If the user's satisfaction with the heating temperature is low, the load balancing of the corresponding air-conditioning equipment is stopped.

[0080] To sum up, in response to the existing problems, the air-conditioning load balancing method invented this time uses the cloud platform to uniformly monitor and control a large number of distributed air-conditioning equipment, providing a practical and effective technical reference for the centralized control of air-conditioning loads; based on the ETP physical model of the single air-conditioner, the calculation method of the adjustable time is derived, which can quickly calculate the time when the current temperature of the air-conditioning equipment reaches the next temperature threshold under different states as the adjustable time; based on the descending order of the adjustable time, the currently turned-on air-conditioning equipment is sorted to form an open group, and the currently closed air-conditioning equipment is sorted to form a closed group. After receiving the instruction of the superior load control, the state of the air-conditioning equipment is adjusted in order to make it take the longest time to reach the next temperature threshold, thereby reducing the frequency of control switching; a custom energy block suppression method is used for power leveling, so that the sum of the air-conditioning loads turned on at each moment is stabilized at the total energy block, and the single continuous energy consumption behavior of the equipment is transformed into multiple intermittent energy consumption, which can realize the efficient application of limited energy and promote the optimal allocation of power resources.

Figure 6 Schematic diagram of an air conditioning load balancing device according to an embodiment of the present invention. Figure 6 As shown, the air conditioning load balancing device according to the embodiment of the present invention specifically includes:

[0083] The control amount determination module 60 is used to receive the load control amount that needs to be reduced or increased, and is specifically used to:

[0084] The load demand is predicted through the machine learning algorithm in the cloud platform, and the load control amount that needs to be reduced or increased is automatically generated based on the load demand.

[0085] The sorting module 62 is used to obtain the adjustable capacity of each air-conditioning device, and calculate the adjustable time of each air-conditioning device in real time, and sort the currently turned-on air-conditioning devices into an open group and sort the currently turned-off air-conditioning devices into a closed group based on the descending order of the adjustable time, specifically for:

[0086] The rated load power of each air-conditioning device is obtained as the corresponding adjustable capacity.

[0087] Based on the duration calculation formula derived from the single air conditioner ETP physical model, use Formula 1 to calculate the adjustable time of each air conditioner:

[0088]

[0091] The initial control module 64 is used to perform initial load control. If the load needs to be reduced, the air-conditioning equipment is selected from the open group in sequence to be turned off. If the load needs to be increased, the air-conditioning equipment is selected from the closed group in sequence to be turned on until the sum of the adjustable capacities of the selected equipment is greater than or equal to the load control amount. The open group and the closed group are updated and maintained. Specifically, it is used to:

[0092] If the load needs to be reduced, the air-conditioning equipment that needs to be turned off will be removed from the turned-on group, the adjustable time will be updated and calculated, and it will be added to the corresponding position in the descending order of the turned-on group; if the load needs to be increased, the air-conditioning equipment that needs to be turned on will be removed from the turned-off group, the adjustable time will be updated and calculated, and it will be added to the corresponding position in the turned-on group in the descending order.

[0093] The power balancing module 66 is used to monitor the status and room temperature of the two groups of air conditioners in real time. When the room temperature of the air conditioner reaches the threshold, the status of the air conditioner is switched and the energy block suppression method is used for power balancing. Specifically, it is used to:

[0094] The total load of the air conditioning equipment cluster after initial regulation is taken as the total energy block;

[0095] If the room temperature of the air-conditioning equipment in the closed group reaches the high threshold, the adjustable capacity of the air-conditioning equipment is obtained as the energy block to be allocated, and some air-conditioning equipment is selected from the open group to be closed, and the room temperature of the selected air-conditioning equipment is lower than the set temperature, until the sum of the adjustable capacities of the selected air-conditioning equipment is greater than or equal to the energy block to be allocated, and the air-conditioning equipment that reaches the high threshold is turned on to stabilize the total amount of energy blocks;
