[0023] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings, but it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0024] As global warming becomes increasingly serious, buildings still rely heavily on fossil fuels for heating, which leads to a large amount of greenhouse gas emissions. Therefore, the transition to more reliable, energy-saving and green building heating methods is imminent. In the context of comprehensive energy development, it is particularly important to improve the overall energy efficiency of the system and save more energy.

[0025] As one of the main energy consumers, buildings have great potential in energy conservation and emission reduction. At present, the demand for low-carbon environmental protection and efficient energy utilization in scenic area buildings is increasing. Photovoltaic and air source heat pump systems have gradually become the preferred solution for power supply and heating systems in scenic area buildings due to their high efficiency, energy saving and environmental protection. The combination of the two has achieved significant energy-saving effects.

[0026] For large-scale building complexes, such as commercial buildings in scenic spots, multiple heat pumps are used to form a group of air source heat pumps to meet their heating needs. However, in the actual application of air source heat pumps, due to the limitation of available space for air source heat pumps, the minimum spacing requirements between air source heat pumps may not be met. When the distance between heat pumps is too close, a single air source heat pump can affect the air temperature around the evaporator of the air source heat pump, causing the surrounding temperature to drop, thereby affecting the heat absorption capacity of other air source heat pumps, thereby reducing the overall thermal efficiency of the system, that is, the cold island effect.

[0027] In some areas, more and more photovoltaic equipment is used and photovoltaic resources are abundant, but due to the single electricity consumption mode and insufficient absorption capacity in the area, a large number of photovoltaic resources are difficult to use locally. The existing scenic spot energy management system fails to fully consider the impact of cold island effect and photovoltaic resource access on system performance, resulting in energy waste and increased operating costs.

[0028] In view of the above problems, an embodiment of the present invention provides an operation scheduling method for air source heat pump units in scenic area building complexes. By acquiring the air source heat pump unit information of the target scenic area, the information of the building complex, the environmental information of the target scenic area and the output power information of the photovoltaic power generation system, the cold island effect and the photovoltaic power generation boundary are introduced as optimization constraints to achieve the coordinated operation of the air source heat pump system and photovoltaics, establish a target energy center model, a target operation scheduling model and a target thermodynamic model, and use the above models to calculate the target operating state parameters of each device. Each device operates with the target operating state parameters to improve the efficiency of the air source heat pump unit, so that the power demand of the target scenic area to the distribution network is minimized while suppressing the cold island effect between the devices, and the optimal operation strategy of the scenic area building complex system is achieved. While maximizing the photovoltaic utilization efficiency, it can reduce the energy operation consumption cost and reduce carbon emissions.

[0029] Figure 1 An application scenario diagram of the operation scheduling method for air source heat pump units in a scenic area building complex according to an embodiment of the present invention is shown.

Through the constructed target energy center model, target operation scheduling model and target thermodynamic model, the server 106 calculates the target operating status parameters of each device.

Correspondingly, the operation scheduling device for the air source heat pump unit for the scenic area building complex provided in the embodiment of the present invention can also be arranged in a server or server cluster that is different from the server 106 and can communicate with the first terminal device 104 and / or the server 106.

[0087] Figure 4 A flow chart of constructing a target operation scheduling model in an operation scheduling method according to an embodiment of the present invention is shown.

[0088] like Figure 4 As shown, the method 400 for constructing a target operation scheduling model in the operation scheduling method of this embodiment includes operations S401 to S404.

[0096] According to an embodiment of the present invention, the distance parameters between each device include the distance between adjacent air source heat pumps, and also include the distance between separated air source heat pumps. For example, the distance parameter between the air source heat pump numbered n1 and the air source heat pump numbered n2 is 0.5m, and the distance parameter between the air source heat pump numbered n1 and the air source heat pump numbered n9 is 6.8m.

[0097] When the distance between air source heat pumps exceeds a certain amount, it is assumed that they are not affected by the cold island effect. The relationship between the distance between each device and the ambient temperature difference is shown in the following formula (8):

[0099] in, The ambient temperature difference caused by the fully loaded air source heat pump numbered n1; is the distance between two different air source heat pumps; is the maximum distance of the cold island effect, set to 9.1629m.

[0100] Considering the cold island effect, based on the influence relationship between the distance between each device and the ambient temperature difference described by the above formula (8), the distance parameters between each device, the operating status parameters of each device and the predetermined ambient temperature parameters, the actual ambient temperature parameters of each device are determined.

[0106] The electric-to-heat conversion efficiency parameter obtained by formula (10) is combined with the power consumption parameters and heat supply parameters of each device, and based on the electric-to-heat conversion relationship of the air source heat pump unit, the electric-to-heat conversion constraint is constructed, as shown in the following formula (11):

[0107] (11)

[0117] In operation S503 , based on the above operations S501 to S502 , a target thermodynamic model is constructed.

[0118] According to an embodiment of the present invention, the target thermodynamic model includes thermal balance constraints of walls and roofs and thermal balance constraints of indoor areas; and the energy parameters of the building complex include heat demand parameters.

[0119] The building envelope includes the enclosures on all sides of the building and the room, such as walls, roofs, etc. The envelope generally has the ability to keep warm, insulate, and be waterproof and moisture-proof. The constructed target thermodynamic model is mainly composed of thermal resistance (R) and thermal capacity (C). R and C represent their heat transfer and thermal insulation capabilities, respectively. In the target thermodynamic model, there are two types of nodes, wall nodes and room nodes, which are connected to each other by R and C according to thermal capacity. The thermal dynamics of scenic area buildings are modeled by using a resistor-capacitor (RC) network to quantify the flexibility of scenic area buildings.

[0120] Furthermore, considering the slow dynamic process of wall heat dissipation and indoor temperature change of scenic area buildings, when constructing the target thermodynamic model, the thermal balance constraints of the wall and roof and the thermal balance constraints of the indoor area were first constructed.

[0121] According to an embodiment of the present invention, the thermodynamic parameters of the building envelope include the heat capacity and thermal resistance of the wall, the wall temperature, the temperature inside the scenic area building, the heat absorption rate and surface area of ​​the wall, the solar radiation received by the wall, etc.

[0128] in, is the indoor gas heat capacity of the scenic spot building numbered n2; , is the thermal resistance in the d direction and the window area; is the window transmittance; T out is the second external environment temperature; The heat required for building numbered n2.

[0129] According to an embodiment of the present invention, based on the thermal balance relationship between the enclosure structures of the building complex and the thermal balance relationship of the indoor area of ​​the building complex, the thermal balance constraints of the wall and the roof and the thermal balance constraints of the indoor area are constructed by using the thermodynamic parameters of the enclosure structures of the building complex, the orientation parameters of the enclosure structures, the parameters of the windows installed on the enclosure structures and the heat capacity parameters of the indoor gas, and then the target thermodynamic model is constructed. The target thermodynamic model is used to simulate the thermodynamic characteristics of the scenic area buildings in the scenic area building complex, taking into account the thermal inertia of the buildings, and exploring the flexibility of the buildings. At the same time, the influence of external environmental factors such as light intensity and solar radiation on the heat demand of the buildings is also considered, and the flexibility of the scenic area buildings is reasonably quantified. The target thermodynamic model combines the target energy center model and the target operation scheduling model to optimize the operation scheduling method of the air source heat pump, improve the energy utilization rate of the heat pump system, reduce the energy consumption of the scenic area building complex, and achieve the minimum electricity demand proposed by the target scenic area to the distribution network.

[0130] According to an embodiment of the present invention, based on the air source heat pump unit information of the target scenic area, the information of the building complex, the environmental information of the target scenic area and the output power information, the target energy center model, the target operation scheduling model and the target thermodynamic model are used to calculate and obtain the target operating status parameters of each device, including: inputting the air source heat pump unit information of the target scenic area, the information of the building complex, the environmental information of the target scenic area and the output power information into the target calculation engine accordingly, and outputting the target operating status parameters.

[0131] For example: the air source heat pump unit information, building complex information, environmental information and output power information of the target scenic area are input into the target calculation engine accordingly, and the output operating status parameters of each target are as follows: the operating status parameter of the air source heat pump numbered n1 is 40%, the operating status parameter of the air source heat pump numbered n2 is 60%, the operating status parameter of the air source heat pump numbered n3 is 100%, the operating status parameter of the air source heat pump numbered n4 is 70%, etc.

[0132] According to an embodiment of the present invention, a target energy center model, a target operation scheduling model and a target thermodynamic model are loaded into the target computing engine.

[0133] According to an embodiment of the present invention, through a target calculation engine loaded with a target energy center model, a target operation scheduling model and a target thermodynamic model, the input air source heat pump unit information of the target scenic spot, the information of the building complex, the environmental information of the target scenic spot and the output power information are calculated to obtain the target operation state parameters for use in the operation scheduling of the air source heat pump units in the scenic spot building complex, thereby improving the energy utilization rate of the heat pump system, reducing the energy consumption of the scenic spot building system, and achieving the minimum electricity demand put forward by the target scenic spot to the distribution network.

[0134] According to an embodiment of the present invention, the above-mentioned operation scheduling method for air source heat pump units for scenic area building complexes takes into account the cold island effect and photovoltaic absorption, and especially optimizes scheduling while considering the cold island effect between the photovoltaic power supply and the air source heat pump in the scenic area, and provides the optimal energy management strategy, thereby providing power and heat for the scenic area building complex to improve energy utilization efficiency, reduce carbon emissions and reduce operating costs.

[0135] Specifically, the present invention realizes the above energy management method by constructing a target energy center model, a target operation scheduling model and a target thermodynamic model. When constructing the target energy center model, the distributed photovoltaic power generation system of the scenic area is fully utilized and coordinated with the external power grid. By dynamically adjusting the power output of the air source heat pump group, the photovoltaic power is consumed locally, so that the system can achieve optimal economic operation under different electricity prices. Based on the real-time electricity price and photovoltaic power generation situation, the load distribution of the system is dynamically adjusted to realize the coordinated scheduling of photovoltaic power generation and power grid power supply. The target operation scheduling model aims to establish an optimization model of the air source heat pump unit. In the scenic building complex, the heating system composed of multiple air source heat pumps (ASHP) meets the heating needs of multiple scenic building complexes. By introducing the cold island effect as a constraint condition of the optimization scheduling model, the operating state of each air source heat pump is optimized to ensure the efficient operation of the system. By using the resistor-capacitor (RC) network model to simulate the thermodynamic characteristics of the scenic building in the scenic building complex, considering the thermal inertia of the building, and exploring the flexibility of the building, the target thermodynamic model is constructed. The model also considers the influence of external environmental factors such as light intensity and solar radiation on the heat demand of the building.

[0136] In particular, during operation, the heat pumps located at the edge of the heat pump group are started first according to the needs of different heat loads to avoid the negative impact of the cold island effect on the performance of the heat pump and suppress the cold island effect. When the load demand is high, the load of the equipment located in the middle of the heat pump group is gradually increased to ensure the efficient operation of the overall system. By intelligently scheduling the local load ratio (PLR) of the air source heat pump, the impact of the cold island effect on system efficiency is avoided, ultimately reducing power consumption, improving the local absorption capacity of photovoltaics, and meeting the heating comfort requirements of scenic area buildings.

[0137] Figure 6A graph showing the relationship between the ambient temperature and the heat output of a heat pump according to an embodiment of the present invention is shown.

[0138] like Figure 6 As shown, as time goes by, the ambient temperature first increases and then decreases. Correspondingly, by scheduling the operation state of the air source heat pump, the heat generation of the air source heat pump changes with the change of the ambient temperature. By utilizing the operation scheduling method of the present invention, the cold island effect is introduced as a constraint condition, and the air source heat pump is optimized and scheduled, so that the air source heat pump can be adjusted in real time according to the actual environmental conditions, which significantly improves the energy efficiency of the heat pump system.

[0139] Figure 7a A diagram showing the state results of an air source heat pump obtained after optimized scheduling according to an embodiment of the present invention is shown. Figure 7b The figure shows the status result of the air source heat pump obtained after scheduling according to the relevant technology.

[0140] like Figure 7a and Figure 7b As shown, the area surrounded by the dotted line represents the setting range of the air source heat pump unit. The air source heat pump is placed within this range at a specific distance and in a specific manner. The closed lines represent isotherms, and different depths represent different temperatures. The specific temperature value is referenced to the scale on the right.

[0141] By using the above-mentioned target operation scheduling model, the air source heat pump after optimized scheduling and the air source heat pump obtained by scheduling without considering the cold island effect of related technologies are simulated and calculated. Figure 7a and Figure 7b As shown, the temperature distribution in the central area of ​​the air source heat pump unit is more uniform after considering the cold island effect, while the temperature difference in the central area of ​​the air source heat pump unit without considering the cold island effect is larger and the temperature value in the central area is lower, indicating that by optimizing the operating state of the air source heat pump group, especially when considering the cold island effect, the present invention significantly improves the energy utilization efficiency of the heat pump system.

[0142] Specifically, the operating efficiency of the air source heat pump unit group and the construction cost of the scenic area are compared when the cold island effect is considered and when the cold island effect is not considered. The results are shown in Table 1:

[0143] Table 1: Comparison of power consumption and total power cost

[0144]

[0145] 1 indicates that the operation scheduling method of the embodiment of the present invention is adopted, and the cold island effect is considered; 2 indicates a method in the related art that does not consider the cold island effect.

[0146] The results show that by adopting the operation scheduling method of the embodiment of the present invention, the operating energy efficiency of the scenic area buildings is reduced by 3.29%, and the total cost is reduced by 3.11%. By adopting the above-mentioned target thermodynamic model, the scenic area building complex can autonomously control the state of the air source heat pump group, effectively reducing energy consumption and energy costs.

[0147] According to an embodiment of the present invention, a method for operating and scheduling air source heat pump units for scenic area buildings is proposed, which takes into account the cold island effect and photovoltaic absorption. The cost of purchasing electricity and the electric and thermal constraints of the energy center are considered to construct a target energy center model. Considering the cold island effect impact constraints and photovoltaic output boundaries, a target operation scheduling model is constructed to achieve the optimal scheduling method for the operation of air source heat pump units. A resistor-capacitor (RC) network is used to simulate the constraints of the thermodynamic process of scenic area buildings, and a target thermodynamic model is constructed to quantify the flexibility of scenic area buildings.

[0148] The impact of the cold island effect between air source heat pumps is studied, including the change in ambient temperature of the air source heat pump when the cold island effect is not considered and the calculation of the ambient temperature of a single air source heat pump considering the cold island effect. The scenic area building complex can autonomously control the status of the air source heat pump group, and compare the energy consumption and electricity cost under different strategies.

[0149] By optimizing the operating state of the air source heat pump group, especially considering the cold island effect, the present invention significantly improves the energy utilization efficiency of the heat pump system. The example shows that after optimized scheduling, the energy consumption of the scenic area building system is reduced by about 3.29%. By adjusting the local load ratio of the air source heat pump, the power consumption is reduced during peak electricity prices, the distributed photovoltaic power generation is maximized, and the overall operating cost of the system is reduced. The experimental results show that compared with the traditional operation method that does not consider the cold island effect, the operating cost of the scenic area building is reduced by about 3.11%. By optimizing the coordinated scheduling of photovoltaic power generation and the power grid, the use of clean energy is maximized, the carbon emissions of the system are reduced, and the low-carbon goal of the scenic area building complex is contributed to. By optimizing the start-stop sequence and load adjustment of the air source heat pump, the negative impact of the cold island effect on the operating performance of the scenic area building system is avoided, ensuring the efficient operation of each air source heat pump.

[0150] The present invention is applicable to the optimization operation of scenic area buildings, especially in areas with distributed photovoltaic power generation and air source heat pump group heating systems. The invention has a high prospect of promotion and application, and can provide efficient energy management solutions for different types of scenic area buildings.
