TECHNICAL FIELD
[0001] The present application relates to the technical field of power control, in particular to a kind of energy storage photovoltaic consumption control method, device, equipment and storage medium. BACKGROUND
[0002] In recent years, the installed capacity of renewable energy such as solar energy and wind energy has rapidly expanded, and the penetration rate of clean energy in the power grid has been continuously improved. However, the influence of weather and other factors makes the power generation have strong volatility and intermittency, which brings the problem of power balance between supply side and demand side. The mismatch between power generation and power consumption will cause a lot of energy waste and cannot meet the user's demand for electricity. The traditional way to solve this problem is energy storage. The building field is an important part of the demand side of electricity, and among them, the air conditioning load is particularly significant. Among the many energy storage methods, water energy storage has the advantages of low cost and small impact on refrigeration conditions. However, relying solely on thermal energy storage units for photovoltaic consumption has limited response speed, and existing variable frequency units are mostly step-variable frequency regulation, with limited step resolution. When the photovoltaic power is fluctuating between two steps of the main unit, the thermal energy storage unit cannot accurately match the power of the unit. In addition, due to the existence of control step switching control dead zone, it is difficult for the thermal energy storage unit to achieve rapid response in the short term. In contrast, although electric energy storage can meet the demand for rapid response and accurate regulation, its investment cost is high and it is difficult to be widely applied. Therefore, how to realize accurate consumption of distributed photovoltaic power using hybrid energy storage air conditioners at a low investment cost is a problem to be solved. SUMMARY
[0003] Therefore, the purpose of the present application is to provide an energy storage photovoltaic consumption control method, device, equipment and storage medium, which can realize effective consumption of distributed photovoltaic power while ensuring indoor thermal comfort. The specific scheme is as follows:
[0004] In a first aspect, the present application discloses an energy storage photovoltaic consumption control method, comprising:
[0005] obtaining the current unit power at the current time, the photovoltaic predicted power at the next time and the environmental temperature of the target heating environment of the heat pump main unit in the thermal control system, and determining whether the environmental temperature meets the preset environmental thermal comfort condition;
[0006] If the environmental temperature meets the preset environmental thermal comfort condition, the current heat pump power level of the heat pump main unit is determined based on the current unit power, and the photovoltaic predicted power is compared with the interval power of the current heat pump power level to determine the frequency adjustment target of the heat pump main unit.
[0007] The system obtains the operating mode of the energy storage tank in the thermal control system, and adjusts the photovoltaic power consumption status of the energy storage tank according to the operating mode and the frequency adjustment target. At the same time, it controls and adjusts the current unit power of the heat pump host based on the preset battery.

[0010] If the photovoltaic predicted power is greater than the upper limit power of the heat pump dead zone, then the heat pump host is determined to be the target for unit frequency increase adjustment.
[0011] If the photovoltaic predicted power is less than the lower limit power of the heat pump dead zone, then the heat pump host is determined to be the target for unit frequency reduction adjustment;
[0012] If the photovoltaic predicted power is greater than the lower limit power of the heat pump dead zone and less than the upper limit power of the heat pump dead zone, then the unit frequency of the heat pump host is determined to remain unchanged.
[0013] Optionally, when the frequency adjustment target is the unit's frequency increase adjustment target, the step of acquiring the operating mode of the energy storage tank in the thermal control system and adjusting the photovoltaic power consumption status of the energy storage tank according to the operating mode and the frequency adjustment target includes:
[0014] Obtain the predicted battery balance and battery preparation operation of the preset battery at the next moment, and determine whether the predicted battery balance is less than the first preset balance judgment value and whether the battery preparation operation meets the first preset operation condition.
[0015] If the predicted battery balance is less than the first preset balance judgment value and the battery preparation operation meets the first preset operation conditions, then the unit frequency increase adjustment target is cancelled, and the preset storage battery is charged to adjust the photovoltaic power consumption status of the energy storage tank.
[0016] If the predicted battery balance is not less than the first preset balance judgment value or the battery preparation operation does not meet the first preset operation condition, then the operating mode of the energy storage tank in the thermal control system is obtained.
[0017] If the operating mode is characterized as an energy storage mode, then based on the unit frequency adjustment target, the proportion of energy storage in the energy storage tank to the energy supplied by the heat pump host is increased;
[0018] If the operating mode is characterized as an energy release mode, then the energy storage tank's energy supply load ratio is reduced based on the unit's frequency adjustment target.
[0019] If the operating mode is characterized as the non-operating mode, then based on the unit frequency adjustment target, the operating mode of the energy storage tank is switched to the energy storage mode, and the proportion of energy storage in the energy storage tank to the energy supplied by the heat pump host is increased.
[0020] Optionally, after reducing the proportion of the energy storage tank's load based on the unit's frequency increase adjustment target, the method further includes:
[0021] Determine whether the energy supply load ratio of the energy storage tank has dropped to 0;
[0022] If the energy storage tank's load-bearing ratio drops to 0, the operating mode of the energy storage tank will be switched to energy storage mode, and the proportion of the energy stored in the energy storage tank to the energy supplied by the heat pump unit will be increased.
[0023] Optionally, when the frequency adjustment target is the unit's frequency reduction adjustment target, the step of acquiring the operating mode of the energy storage tank in the thermal control system and adjusting the photovoltaic power consumption status of the energy storage tank according to the operating mode and the frequency adjustment target includes:
[0024] Obtain the predicted battery balance and battery preparation operation of the preset battery at the next moment, and determine whether the predicted battery balance is greater than the second preset balance judgment value and whether the battery preparation operation meets the second preset operation condition.
[0025] If the predicted battery balance is greater than the second preset balance judgment value and the battery preparation operation meets the second preset operation conditions, then the unit frequency reduction adjustment target is cancelled, and the preset battery is discharged to adjust the photovoltaic power consumption status of the energy storage tank.
[0026] If the predicted battery balance is not greater than the second preset balance judgment value or the battery preparation operation does not meet the second preset operation conditions, then the operating mode of the energy storage tank in the thermal control system is obtained.
[0027] If the operating mode is characterized as an energy storage mode, then the proportion of energy stored in the energy storage tank to the energy supplied by the heat pump host is reduced based on the unit frequency reduction adjustment target.
[0028] If the operating mode is characterized as an energy release mode, then the energy storage tank's load-bearing ratio is increased based on the unit's frequency reduction adjustment target;
[0029] If the operating mode is characterized as the non-operating mode, then based on the unit frequency reduction adjustment target, the operating mode of the energy storage tank is switched to the energy release mode, and the energy storage tank's load-bearing ratio is increased.
[0030] Optionally, after reducing the proportion of energy stored in the energy storage tank to the energy supplied by the heat pump unit based on the unit frequency reduction adjustment target, the method further includes:
[0031] Determine whether the proportion of energy stored in the energy storage tank to the energy supplied by the heat pump unit has decreased to 0;
[0032] If the proportion of energy stored in the energy storage tank to the energy supplied by the heat pump unit drops to 0, the operating mode of the energy storage tank will be switched to the energy release mode, and the proportion of the energy supplied by the energy storage tank to bear the load will be increased.
[0033] Optionally, the method further includes:
[0034] Obtain the predicted battery balance and battery preparation operation of the preset battery at the next moment, and determine whether the predicted battery balance is less than the first preset balance judgment value and whether the battery preparation operation meets the first preset operation condition.
[0035] If the predicted battery balance is less than the first preset balance judgment value and the battery preparation operation meets the first preset operation conditions, then the heat pump host is determined to be the unit frequency reduction adjustment target, and the process jumps to the step of obtaining the operating mode of the energy storage tank in the thermal control system.
[0036] Determine whether the predicted battery balance is greater than the second preset balance judgment value and whether the battery preparation operation meets the second preset operation condition.
[0037] If the predicted battery balance is greater than the second preset balance judgment value and the battery preparation operation meets the second preset operation conditions, then the heat pump host is determined to be the unit frequency increase adjustment target, and the process jumps to the step of obtaining the operating mode of the energy storage tank in the thermal control system.
[0038] Optionally, the step of controlling and adjusting the current unit power of the heat pump host based on a preset battery includes:
[0039] Within a preset response time, determine whether the real-time unit power of the heat pump host after adjustment is equal to the photovoltaic predicted power;
[0040] If the adjusted real-time unit power is greater than the photovoltaic predicted power, the preset battery is controlled to discharge to supplement the missing photovoltaic power generation until the adjusted real-time unit power of the heat pump host is equal to the photovoltaic predicted power.
[0041] If the adjusted real-time unit power is less than the photovoltaic predicted power, the preset battery is controlled to charge in order to absorb the remaining photovoltaic power generation until the adjusted real-time unit power of the heat pump host is equal to the photovoltaic predicted power.
[0042] Secondly, this application discloses a photovoltaic power consumption control device, comprising:
[0043] The power acquisition module is used to acquire the current unit power of the heat pump host in the thermal control system at the current moment, the photovoltaic predicted power at the next moment, and the ambient temperature of the target heating environment, and to determine whether the ambient temperature meets the preset environmental thermal comfort conditions.
[0044] The frequency adjustment target determination module is used to determine the current heat pump power level of the heat pump host based on the current unit power if the ambient temperature meets the preset ambient thermal comfort conditions, and compare the photovoltaic predicted power with the range power of the current heat pump power level to determine the frequency adjustment target of the heat pump host.
[0045] The photovoltaic power absorption module is used to acquire the operating mode of the energy storage tank in the thermal control system, and adjust the photovoltaic power absorption status of the energy storage tank according to the operating mode and the frequency adjustment target. At the same time, it controls and adjusts the current unit power of the heat pump host based on the preset battery.
[0046] Thirdly, this application discloses an electronic device, including:
[0047] Memory, used to store computer programs;
[0048] A processor is used to execute the computer program to implement the aforementioned photovoltaic power consumption control method.
[0049] Fourthly, this application discloses a computer-readable storage medium for storing a computer program, which, when executed by a processor, implements the aforementioned photovoltaic power consumption control method.
[0050] As can be seen, in this application, the current unit power of the heat pump host in the thermal control system, the photovoltaic predicted power at the next moment, and the ambient temperature of the target heating environment are obtained, and it is determined whether the ambient temperature meets the preset ambient thermal comfort conditions. If the ambient temperature meets the preset ambient thermal comfort conditions, the current heat pump power level of the heat pump host is determined based on the current unit power, and the photovoltaic predicted power is compared with the interval power of the current heat pump power level to determine the frequency adjustment target of the heat pump host. The operating mode of the energy storage tank in the thermal control system is obtained, and the photovoltaic power consumption status of the energy storage tank is adjusted according to the operating mode and the frequency adjustment target. At the same time, the current unit power of the heat pump host is controlled and adjusted based on the preset battery. This approach employs a hybrid energy storage air conditioning system for precise building energy consumption tracking of photovoltaic (PV) power. The primary means of PV tracking is through dynamic adjustment of the generator unit's power using a water storage unit, supplemented by a very small-capacity electrical energy storage unit for precise power replenishment. This solves the problem of slow response speed in thermal energy storage air conditioning, which cannot quickly track changes in PV power generation. It also addresses the difficulty of adjustment when PV power generation falls between different generator levels due to generator unit tiers. Furthermore, the periodic charging and discharging balance of the electrical energy storage unit during the coupled regulation significantly reduces the required electrical energy storage capacity. The proposed hybrid energy storage air conditioning control method introduces a very small-capacity electrical energy storage system into the traditional water storage air conditioning system, solving two major problems: the inability of water storage to achieve rapid and precise response, and the high cost of using only electrical energy storage for PV integration. It can effectively integrate distributed PV power while ensuring indoor thermal comfort. Attached Figure Description

[0061] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0062] In recent years, the installed capacity of renewable energy sources such as solar and wind power has expanded rapidly, and the penetration rate of clean energy in the power grid has continued to increase. However, factors such as weather have led to strong fluctuations and intermittentity in power generation, resulting in power balance issues on both the supply and demand sides. Therefore, this application will specifically introduce a photovoltaic energy storage consumption control method that can solve the above problems.
[0063] See Figure 1 As shown in the figure, this application discloses a method for controlling the absorption of photovoltaic power in energy storage, including:
[0064] Step S11: Obtain the current unit power of the heat pump host in the thermal control system at the current moment, the photovoltaic predicted power at the next moment, and the ambient temperature of the target heating environment, and determine whether the ambient temperature meets the preset environmental thermal comfort conditions.
[0065] In this embodiment, the energy storage tank is directly connected to the heat pump chilled water loop to provide cooling for the target environment. For example... Figure 2 As shown, the energy storage tank is characterized as being in a non-operational mode (hereinafter referred to as Mode 1), in which only the heat pump unit provides cooling for the room. Figure 3 As shown, the energy storage tank represents the energy storage mode (hereinafter referred to as Mode 2), in which the heat pump unit simultaneously cools the room and stores energy in the water tank; asFigure 4 As shown, the energy storage tank represents the energy release mode (hereinafter referred to as Mode 3), in which the heat pump unit and the water tank simultaneously provide cooling for the room. Figure 5 As shown, common heat pumps are divided into fixed-frequency and variable-frequency types. However, variable-frequency heat pumps also perform more detailed power grading, adjusting the power according to the target level. In actual use, the current unit power of the heat pump host in the thermal control system is first obtained, and then the photovoltaic predicted power for the next moment is obtained according to the preset power prediction method. Then, it is determined whether the current ambient temperature meets the preset ambient thermal comfort conditions.
[0066] Step S12: If the ambient temperature meets the preset ambient thermal comfort conditions, the current heat pump power level of the heat pump host is determined based on the current unit power, and the photovoltaic predicted power is compared with the range power of the current heat pump power level to determine the frequency adjustment target of the heat pump host.
[0067] In this embodiment, while ensuring indoor thermal comfort, the water-storage air conditioner regulates the main unit power by adjusting the energy storage / release. Therefore, in this embodiment, comparing the photovoltaic predicted power with the range power of the current heat pump power level to determine the frequency adjustment target of the heat pump main unit includes: comparing the photovoltaic predicted power with the lower limit power and upper limit power of the heat pump dead zone corresponding to the range power of the current heat pump power level; if the photovoltaic predicted power is greater than the upper limit power of the heat pump dead zone, the heat pump main unit is determined to be the target for frequency increase adjustment; if the photovoltaic predicted power is less than the lower limit power of the heat pump dead zone, the heat pump main unit is determined to be the target for frequency decrease adjustment. That is, first, the range power corresponding to the current heat pump power level is determined. Then, the frequency adjustment target is determined.
[0068] Specifically, when the target power When the power output exceeds the unit's starting power P0, the heat pump unit starts and maintains operation at level 1; during the operation of the heat pump unit at level 1, when the target power... If the power consumption exceeds the upper limit of the heat pump dead zone P11 (level 1), the heat pump unit will increase its frequency and enter level 2 operation. Conversely, if the heat pump unit is operating at level 6, when the target power... If the temperature is below the lower limit of the heat pump dead zone P60 (level 6), the heat pump unit will reduce its frequency and enter level 5 operation; during level 5 operation, when the target power... If the temperature is below the lower limit of the heat pump dead zone P50 (level 5), the heat pump unit will continue to reduce its frequency and enter level 4 operation. When the unit's target power... If the temperature is below the lower limit of the heat pump dead zone P10, the heat pump unit will shut down.
[0069] In addition, if the photovoltaic predicted power is greater than the lower limit power of the heat pump dead zone and less than the upper limit power of the heat pump dead zone, it means that the power operation power of the unit remains unchanged.
[0070] Step S13: Obtain the operating mode of the energy storage tank in the thermal control system, and adjust the photovoltaic power consumption status of the energy storage tank according to the operating mode and the frequency adjustment target. At the same time, control and adjust the current unit power of the heat pump host based on the preset battery.
[0071] like Figure 6 As shown, in one specific embodiment, when the frequency adjustment target is the unit's frequency increase adjustment target, the step of obtaining the operating mode of the energy storage tank in the thermal control system and adjusting the photovoltaic power consumption status of the energy storage tank according to the operating mode and the frequency adjustment target includes: obtaining the predicted battery balance value and battery preparation operation of the preset battery at the next moment, and determining whether the predicted battery balance value is less than a first preset balance judgment value and the battery preparation operation meets a first preset operation condition; if the predicted battery balance value is less than the first preset balance judgment value and the battery preparation operation meets the first preset operation condition, then the unit's frequency increase adjustment target is canceled, and the preset battery is charged to improve the photovoltaic power consumption status of the energy storage tank. The power consumption status is adjusted; if the predicted battery balance is not less than the first preset balance judgment value or the battery preparation operation does not meet the first preset operation conditions, the operating mode of the energy storage tank in the thermal control system is obtained; if the operating mode is characterized as energy storage mode, the proportion of energy storage in the energy storage tank to the power supply of the heat pump host is increased based on the unit frequency adjustment target; if the operating mode is characterized as energy release mode, the proportion of energy supply load borne by the energy storage tank is reduced based on the unit frequency adjustment target; if the operating mode is characterized as non-operation mode, the operating mode of the energy storage tank is switched to the energy storage mode based on the unit frequency adjustment target, and the proportion of energy storage in the energy storage tank to the power supply of the heat pump host is increased. It should be noted that when determining the frequency adjustment target as the unit frequency increase adjustment target, it is necessary to obtain the battery SOC (State of Charge) margin of the preset battery after the unit adjustment. If the battery SOC margin is less than 0.4 and the unit needs to continue discharging after frequency increase, in order to ensure that the battery can perform periodic charging and discharging balance and that the photovoltaic regulation can proceed normally, the unit frequency increase adjustment is not performed, and the battery needs to be charged.
[0072] The process of reducing the load proportion of the energy storage tank based on the unit's frequency adjustment target further includes: determining whether the load proportion of the energy storage tank has decreased to 0; if the load proportion of the energy storage tank has decreased to 0, then the operating mode of the energy storage tank is switched to energy storage mode, and the proportion of the energy storage tank's energy storage to the heat pump unit's energy supply is increased. Specifically, when the frequency adjustment target is the unit's frequency adjustment target, if it is operating in mode one (only the heat pump unit provides indoor cooling), it switches to mode two (the heat pump unit provides indoor cooling while also storing cold in the water tank), and gradually increases the power output by gradually increasing the proportion of the water tank's energy storage to the unit's energy supply. If it is operating in mode two (the heat pump unit provides indoor cooling while also storing cold in the water tank), it directly increases the proportion of the water tank's energy storage to the unit's energy supply to gradually increase the power output. If it is operating in mode three (the heat pump unit and the water tank provide indoor cooling simultaneously), it decreases the proportion of the water tank's energy supply to the total energy supply to increase the power output. If the water tank's energy supply ratio drops to 0 and power is still required to increase, switch to mode two (the heat pump unit provides indoor cooling while simultaneously storing cold in the water tank), and increase the proportion of energy stored in the water tank to the main unit's energy supply to gradually increase power.
[0073] In addition, combined Figure 5 As can be seen from the content, in actual operation, it is possible for the predicted photovoltaic power to be greater than the upper limit power of the heat pump dead zone while being less than the lower limit power of the heat pump dead zone at the next higher power level. For example, it might be greater than the upper limit power of the heat pump dead zone at level 3, but less than the lower limit power of the heat pump dead zone at level 4. Figure 6 In situations where the generator set power remains constant, it's necessary to first predict the pre-set battery SOC (State of Charge) margin after generator set adjustments. If the battery SOC margin is greater than 0.6% and further charging is required, the battery needs to be discharged, and the generator set's frequency is increased to a higher frequency range. Then, the water tank operating mode is determined, converting excess electrical energy into heat energy for the water tank. If the battery SOC margin is less than 0.4% and further discharge is required, the battery is charged, and the generator set's frequency is decreased to a lower frequency range. Then, the water tank operating mode is determined, converting heat energy into electrical energy. This ensures that the battery meets real-time adjustment requirements during both charging and discharging, while reducing the total battery capacity requirement.
[0074] In another specific embodiment, when the frequency adjustment target is the unit frequency reduction adjustment target, the step of obtaining the operating mode of the energy storage tank in the thermal control system and adjusting the photovoltaic power consumption status of the energy storage tank according to the operating mode and the frequency adjustment target includes: obtaining the predicted battery balance value and battery preparation operation of the preset battery at the next moment, and determining whether the predicted battery balance value is greater than a second preset balance judgment value and whether the battery preparation operation meets the second preset operation condition; if the predicted battery balance value is greater than the second preset balance judgment value and the battery preparation operation meets the second preset operation condition, then the unit frequency reduction adjustment target is canceled, and the preset battery is discharged to improve the energy storage capacity. The photovoltaic power consumption status of the water tank is adjusted; if the predicted battery capacity is not greater than the second preset capacity judgment value or the battery preparation operation does not meet the second preset operation conditions, the operating mode of the energy storage water tank in the thermal control system is obtained; if the operating mode is characterized as energy storage mode, the proportion of energy storage in the energy storage water tank to the energy supply of the heat pump host is reduced based on the unit frequency reduction adjustment target; if the operating mode is characterized as energy release mode, the proportion of energy supply load borne by the energy storage water tank is increased based on the unit frequency reduction adjustment target; if the operating mode is characterized as non-operation mode, the operating mode of the energy storage water tank is switched to the energy release mode based on the unit frequency reduction adjustment target, and the proportion of energy supply load borne by the energy storage water tank is increased. It should be noted that when determining the frequency adjustment target as the unit frequency reduction adjustment target, it is necessary to obtain the battery SOC margin of the preset battery after the unit adjustment. If the battery SOC margin is greater than 0.6 and the unit needs to continue charging after frequency reduction, in order to ensure that the subsequent photovoltaic adjustment work can proceed normally, the unit frequency reduction adjustment is not performed, and the battery needs to be discharged.
[0075] The process of reducing the proportion of energy stored in the energy storage tank to the energy supplied by the heat pump unit based on the frequency reduction adjustment target of the unit further includes: determining whether the proportion of energy stored in the energy storage tank to the energy supplied by the heat pump unit has decreased to 0; if the proportion of energy stored in the energy storage tank to the energy supplied by the heat pump unit has decreased to 0, then the operating mode of the energy storage tank is switched to the energy release mode, and the load-bearing proportion of the energy supplied by the energy storage tank is increased. Specifically, when the frequency adjustment target is the frequency reduction adjustment target of the unit, if the energy storage tank is operating in mode one (only the heat pump unit provides indoor cooling), it is switched to mode three (both the heat pump unit and the water tank provide indoor cooling simultaneously), and the proportion of energy supplied by the water tank to the total energy supply is gradually increased, thereby achieving a gradual reduction in power. If it is operating in mode three (both the heat pump unit and the water tank provide indoor cooling simultaneously), the proportion of energy supplied by the water tank to the total energy supply is directly increased to achieve a gradual reduction in power. If operating in Mode 2 (the heat pump unit provides indoor cooling while simultaneously storing cold in the water tank), the proportion of energy stored in the water tank to the main unit's energy supply is reduced, thus gradually reducing power. If the proportion of energy stored in the water tank drops to 0 and power still needs to be reduced, then the system switches to Mode 3 (the heat pump unit and the water tank simultaneously provide indoor cooling) and increases the proportion of energy supplied by the water tank to the total energy supply, further gradually reducing power.
[0076] In another specific embodiment, after determining that the unit frequency of the heat pump host remains unchanged, the method further includes: obtaining the predicted battery balance value and battery preparation operation of the preset battery at the next moment, and determining whether the predicted battery balance value is less than the first preset balance judgment value and the battery preparation operation meets the first preset operation condition; if the predicted battery balance value is less than the first preset balance judgment value and the battery preparation operation meets the first preset operation condition, then the heat pump host is determined as the target for unit frequency reduction adjustment, and the process jumps to the step of obtaining the operating mode of the energy storage tank in the thermal control system; determining whether the predicted battery balance value is greater than the second preset balance judgment value and whether the battery preparation operation meets the second preset operation condition; if the predicted battery balance value is greater than the second preset balance judgment value and the battery preparation operation meets the second preset operation condition, then the heat pump host is determined as the target for unit frequency increase adjustment, and the process jumps to the step of obtaining the operating mode of the energy storage tank in the thermal control system. That is, if the preset battery SOC balance is less than 0.4 and further discharge is required, the heat pump unit is identified as the target for frequency reduction adjustment. Subsequently, the operating mode of the energy storage tank in the thermal control system is obtained to perform frequency reduction operation, converting the tank's heat energy into electrical energy to charge the battery. Conversely, if the preset battery SOC balance is greater than 0.6 and further charging is required, the heat pump unit is identified as the target for frequency increase adjustment. Subsequently, the operating mode of the energy storage tank in the thermal control system is obtained to perform frequency increase operation, converting battery electrical energy into tank heat energy to discharge the battery.
[0077] In this embodiment, the control and adjustment of the current unit power of the heat pump host based on the preset battery includes: within a preset response time, determining whether the adjusted real-time unit power of the heat pump host is equal to the photovoltaic predicted power; if the adjusted real-time unit power is greater than the photovoltaic predicted power, then the preset battery is controlled to discharge to supplement the missing photovoltaic power generation until the adjusted real-time unit power of the heat pump host equals the photovoltaic predicted power; if the adjusted real-time unit power is less than the photovoltaic predicted power, then the preset battery is controlled to charge to absorb the remaining photovoltaic power generation until the adjusted real-time unit power of the heat pump host equals the photovoltaic predicted power. It should be noted that the heat pump air conditioning system is a thermal control system, and the heat pump host adjusts its power according to the return water temperature. The existence of the heat pump dead zone controlled by the chilled water temperature also determines the system's response speed. Due to the influence of the above factors (heat pump dead zone during gear adjustment, thermal inertia of the thermal control system), the response time of the water storage air conditioning system is approximately 5-10 minutes, which cannot achieve the purpose of real-time photovoltaic absorption. In practice, due to the slow response of water regulation, it is essential to utilize a pre-installed battery in conjunction with the water tank for coordinated / complementary control during photovoltaic (PV) power absorption regulation. Therefore, in actual operation, the water tank and the pre-installed battery work together to regulate the thermal control system. Within the response time of the water-storage air conditioner, if the operating power exceeds the target power, the battery will rapidly discharge to compensate; if the operating power is lower than the target power, the battery will quickly charge to absorb the excess PV power. This synergistic effect enables real-time PV power absorption. With the introduction of electrical energy storage, the response time is approximately 10-30 seconds, achieving real-time PV power absorption.
[0078] Specifically, in actual operation, such as Figure 7As shown, there are two main control logics: dual-storage coordinated control and dual-storage complementary control. The dual-storage coordinated control, as shown at point A, involves both water storage and battery energy storage / release simultaneously, and both water storage and battery energy storage simultaneously to ensure the unit's power output closely matches the photovoltaic power generation. The dual-storage complementary control, as shown at point D, actively regulates the two types of energy storage (the degree of mutual conversion) during unit control. Specifically, water storage units store energy while batteries discharge (electrical energy is converted into heat energy; the battery capacity is constantly adjusted to ensure charging and discharging). Water storage releases energy while batteries charge (heat energy is converted into electrical energy; the higher quality electrical energy compared to heat energy enables a faster, higher-power, and more precise response than the unit can achieve). Using the technology mentioned in this solution, rapid photovoltaic fluctuations can be addressed. As shown at point B, when photovoltaic power generation fluctuates rapidly, water storage cannot respond due to its regulatory inertia. Therefore, the method described in this application allows for precise photovoltaic absorption using small-capacity electrical storage charging and discharging. In addition, if strong photovoltaic fluctuations are predicted, as shown at point C, it is determined whether the battery SOC meets the charging / discharging requirements for subsequent adjustments. The proportion of hydro-storage is proactively reduced in advance, and the battery charging power (converting heat energy into electrical energy) is increased to ensure sufficient battery power for load shedding during the event. As shown in E, red represents battery charging and blue represents battery discharging. It can be seen that during the entire photovoltaic absorption process, the battery achieves periodic charge-discharge balance, requiring only a smaller capacity battery, significantly reducing system costs. In this way, the proportion of energy storage / release can be allocated and converted according to different event requirements, fully considering energy characteristics, and enabling precise and rapid control of unit power to absorb photovoltaic power generation.
[0079] As can be seen, in this application, the current unit power of the heat pump host in the thermal control system, the photovoltaic predicted power at the next moment, and the ambient temperature of the target heating environment are obtained, and it is determined whether the ambient temperature meets the preset ambient thermal comfort conditions. If the ambient temperature meets the preset ambient thermal comfort conditions, the current heat pump power level of the heat pump host is determined based on the current unit power, and the photovoltaic predicted power is compared with the interval power of the current heat pump power level to determine the frequency adjustment target of the heat pump host. The operating mode of the energy storage tank in the thermal control system is obtained, and the photovoltaic power consumption status of the energy storage tank is adjusted according to the operating mode and the frequency adjustment target. At the same time, the current unit power of the heat pump host is controlled and adjusted based on the preset battery. This approach employs a hybrid energy storage air conditioning system for precise photovoltaic (PV) tracking of building energy consumption. The primary means of PV tracking is through dynamic adjustment of the generator unit's power using a water-based energy storage unit, supplemented by a minimal-capacity electrical energy storage unit for precise power replenishment. This solves the problem of slow response speed in thermal energy storage air conditioning, which cannot quickly track changes in PV power generation. It also addresses the difficulty of adjustment when PV power generation falls between different generator levels due to generator unit tiers. Furthermore, the periodic charging and discharging balance of the electrical energy storage unit during the coupled regulation significantly reduces the required electrical energy storage capacity. The proposed hybrid energy storage air conditioning control method introduces minimal-capacity electrical energy storage into traditional water-based air conditioning, resolving two major issues: the inability of water storage to achieve rapid and precise response, and the high cost of relying solely on electrical energy storage for PV integration. With efficient thermoelectric dual-source coupling, precise PV integration can be achieved, contributing to the development of real-time zero-energy buildings.
