[0021] The following describes the energy storage and supply methods, systems, devices and equipment based on clean energy according to the embodiments of the present application with reference to the accompanying drawings.

[0022] Figure 1 This is a flow chart of a method for storing and supplying clean energy according to an embodiment of the present application. Figure 1 As shown, the method includes:

[0023] S101, obtaining the collected first clean energy, obtaining the second clean energy required for the first round of electric energy conversion from the first clean energy, and obtaining the first electric energy based on the second clean energy.

[0024] In the embodiment of the present application, electric energy can be converted based on the collected clean energy, thereby realizing the supply of electric energy to the user cluster.

[0025] The collected clean energy may be determined as the first clean energy, wherein the first clean energy may be solar energy, wind energy, geothermal energy, or other types of clean energy, which are not specifically limited here.

[0026] In this scenario, the first clean energy can be converted based on the energy generation method corresponding to the first clean energy, wherein each round of electric energy conversion has a corresponding clean energy set consumption. In this scenario, the clean energy required for the current round of electric energy conversion can be obtained from the first clean energy based on the clean energy set consumption, wherein the current round of electric energy conversion can be marked as the first round of electric energy conversion, and the clean energy obtained from the first clean energy based on the clean energy set consumption corresponding to the first round of electric energy conversion can be determined as the second clean energy required for the first round of electric energy conversion.

[0027] Furthermore, an electric energy conversion strategy corresponding to the second clean energy is obtained to convert the second clean energy into electric energy, and the converted electric energy is determined as the first electric energy.

[0028] As an example, if the first clean energy is set to solar energy, then based on the strategy of converting electric energy based on solar energy in the related art, the second clean energy obtained from the first clean energy can be converted into electric energy to obtain the first electric energy.

[0029] S102, obtaining a third clean energy to be stored from the first clean energy, and performing energy storage processing on the third clean energy to obtain a fourth clean energy.

[0030] In an embodiment of the present application, part of the first clean energy may not participate in the first round of electric energy conversion. In this scenario, part of the clean energy to be stored is obtained from the remaining clean energy that does not participate in the first round of electric energy conversion, and the part of the clean energy to be stored is determined as the third clean energy.

[0031] Optionally, the storage of clean energy has a preset storage setting amount. In this scenario, based on the storage setting amount, the clean energy corresponding to the storage setting amount can be obtained from the remaining clean energy that has not participated in the first round of electric energy conversion and determined as the third clean energy to be stored.

[0032] Furthermore, an energy storage method corresponding to the third clean energy is obtained, and based on the method, energy storage processing is performed on the third clean energy, and the energy that has been stored after processing is determined as the fourth clean energy.

[0033] As an example, if the third clean energy is set to geothermal energy, the third clean energy can be stored based on the method of storing geothermal energy in the relevant technology, and the stored energy can be determined as the fourth clean energy.

[0034] S103, in response to identifying that a fifth clean energy other than the second clean energy and the third clean energy exists in the first clean energy, performing a second round of electric energy conversion on the fourth clean energy and the fifth clean energy to obtain second electric energy.

[0035] In an embodiment of the present application, when performing electrical energy conversion of the second clean energy and energy storage of the third clean energy, there may still be some remaining clean energy in the first clean energy. The remaining clean energy in the first clean energy except the second clean energy and the third clean energy can be determined as the fifth clean energy in the first clean energy.

[0036] As an example, the first clean energy is set to be the energy obtained by continuously collecting clean energy within a set time range. In this example, after obtaining the second clean energy and the third clean energy, new first clean energy may be continuously collected. This part of the new first clean energy that is continuously collected and the remaining part of the original first clean energy can be determined as the fifth clean energy.

[0037] In an embodiment of the present application, the third clean energy can be processed for energy storage to obtain a fourth clean energy in a storage state. In this scenario, the fourth clean energy in the storage state and the fifth clean energy can be processed for electric energy conversion together, and the electric energy conversion performed in this scenario can be determined as the second round of electric energy conversion, and then the electric energy obtained based on the second round of electric energy conversion can be determined as the second electric energy.

[0038] S104: Supply energy to the user cluster based on the first electric energy and the second electric energy.

[0039] In the embodiment of the present application, the user cluster has a preset power supply method, and the first power and the second power can be output to the user cluster based on the preset power supply method to realize power supply to the user cluster.

[0040] The energy storage and energy supply method based on clean energy proposed in the present application obtains the collected first clean energy, and converts the second clean energy in the first clean energy into electric energy to obtain the first electric energy, obtains the third clean energy to be stored from the first clean energy, and stores the third clean energy to obtain the fourth clean energy in the storage state, and in the scenario where the existence of the fifth clean energy is identified, the fourth clean energy and the fifth clean energy are converted into electric energy to obtain the second electric energy, and then the user cluster is supplied with energy based on the first electric energy and the second electric energy. In the present application, by converting the first clean energy into the first electric energy and the second electric energy, the energy utilization rate of the first clean energy is improved. In the scenario of supplying energy based on the first electric energy and the second electric energy, the probability of the abnormal situation of insufficient power supply in the user cluster is reduced, the stability of the energy supply of the user cluster is improved, and the utilization method and utilization effect of clean energy are optimized.

[0041] In the above embodiments, the clean energy supply method can also be combined with Figure 2 understand, Figure 2 This is a flow chart of a method for storing and supplying clean energy according to another embodiment of the present application. Figure 2 As shown, the method includes:

[0042] S201, obtaining the collected first clean energy, obtaining the second clean energy required for the first round of electric energy conversion from the first clean energy, and obtaining the first electric energy based on the second clean energy.

[0043] In an embodiment of the present application, multiple rounds of electric energy conversion can be performed on the first clean energy, wherein the electric energy converted from the first round of electric energy conversion directly based on the collected first clean energy can be determined as the first electric energy obtained based on the first clean energy.

[0044] Optionally, a first conversion capacity of a first round of electric energy conversion may be obtained, and based on the first conversion capacity, a second clean energy required for the first round of electric energy conversion may be obtained from the first clean energy.

[0045] In the embodiment of the present application, the first round of electric energy conversion has a preset production capacity, and the production capacity can be determined as the first conversion capacity of the first round, wherein the first conversion capacity can be the upper limit value of the production capacity of electric energy conversion that can be achieved by the electric energy conversion component in the first round, or it can be the preset value of the production capacity corresponding to the electric energy conversion achieved by the electric energy conversion component, which is not specifically limited here.

[0046] In this scenario, due to the limitation of the first conversion capacity, the first clean energy may not be able to achieve the conversion of all clean energy in the first round of electric energy conversion. In this scenario, part of the clean energy in the first clean energy used for the first round of electric energy conversion can be determined as the second clean energy in the first clean energy.

[0047] Among them, part of the clean energy in the first clean energy that can meet the first conversion capacity required can be determined as the second clean energy in the first clean energy.

[0048] Optionally, the second clean energy is converted into electric energy based on a preset electric energy conversion strategy to obtain the first electric energy.

[0049] In the embodiment of the present application, the electric energy conversion strategy adopted by the second clean energy can be determined based on the clean energy power generation method in the relevant technology. It can be understood that the clean energy power generation method in the relevant technology can be utilized based on the electric energy conversion strategy, so as to generate electricity based on the second clean energy and obtain the first electric energy generated in the first round.

[0050] As an example, if the first clean energy is set to solar energy, the electric energy conversion strategy adopted by the second clean energy can be determined based on the solar power generation method, and then the solar power generation method in the related technology can be utilized based on the electric energy conversion strategy, so as to obtain the first electric energy by solar power generation based on the second clean energy.

[0051] S202, obtaining a third clean energy required for energy storage from the first clean energy, and performing energy storage processing on the third clean energy to obtain a fourth clean energy.

[0052] Optionally, a preset clean energy storage capacity is obtained, and based on the clean energy storage capacity, a third clean energy is obtained from the first clean energy, and the third clean energy is subjected to phase change energy storage processing to obtain a fourth clean energy.

[0053] In the embodiment of the present application, in a scenario where the second clean energy is part of the first clean energy, there is still some remaining clean energy in the first clean energy. In this scenario, this part of the clean energy can be utilized.

[0054] Optionally, the remaining clean energy may be stored, and then the remaining clean energy may be utilized by utilizing the clean energy in the stored state.

[0055] As a possible implementation method, the remaining clean energy may be subjected to phase change energy storage processing, wherein the portion of clean energy in the first clean energy used for phase change energy storage processing may be determined as the third clean energy in the first clean energy.

[0056] In the embodiment of the present application, the phase change energy storage has a preset energy storage capacity, and the energy storage capacity can be determined as the preset clean energy storage capacity corresponding to the phase change energy storage, wherein the clean energy storage capacity can be the upper limit energy storage capacity that can be achieved by the phase change energy storage, or it can be the preset energy storage capacity that can be achieved by the phase change energy storage, which is not specifically limited here.

[0057] In this scenario, part of the clean energy that can meet the clean energy storage capacity can be obtained from the remaining part of the first clean energy except the second clean energy, and this part of the clean energy can be determined as the third clean energy used for energy storage in the first clean energy, and the third clean energy can be stored based on the preset phase change energy storage process, and the clean energy in the storage state obtained after the energy storage process can be determined as the fourth clean energy.

[0058] As an example, Figure 3 As shown, the first clean energy is set to Figure 3 The clean energy collected by 1-solar thermal collector is shown. In this example, the third clean energy in the first clean energy collected by 1-solar thermal collector needs to be processed by phase change energy storage.

[0059] like Figure 3 As shown, the carbon dioxide flowing from the 2-carbon dioxide storage tank to the 1-solar collector and flowing out from the 1-solar collector can flow to the 3-stacked bed phase change heat storage device via the 17-valve and the 16-fan, and the part of the carbon dioxide is heat exchanged by the phase change material filled in the 3-stacked bed phase change heat storage device, thereby realizing the phase change energy storage of the third clean energy in the first clean energy in the 3-stacked bed phase change heat storage device, wherein the carbon dioxide after heat exchange in the 3-stacked bed phase change heat storage device flows out of the 3-stacked bed phase change heat storage device and can flow back to the 2-carbon dioxide storage tank via the 18-valve and the 19-valve, thereby completing the complete phase change energy storage process.

[0060] Further, Figure 3 In the scenario shown, the clean energy in the storage state obtained by phase change energy storage through the 3-stacked bed phase change heat storage device is determined as the fourth clean energy, wherein Figure 3 In the scenario shown, the fourth clean energy may be thermal energy in a stored state.

[0061] S203, performing a second round of electric energy conversion to obtain second electric energy.

[0062] Optionally, in response to identifying that a fifth clean energy other than the second clean energy and the third clean energy exists in the first clean energy, a second round of electric energy conversion is performed on the fourth clean energy and the fifth clean energy to obtain second electric energy.

[0063] In the embodiments of the present application, the details of this step can be understood by referring to the relevant information in the above embodiments, which will not be repeated here.

[0064] Optionally, in response to identifying that a fifth clean energy other than the second clean energy and the third clean energy does not exist in the first clean energy, a second round of electric energy conversion is performed on the fourth clean energy to obtain second electric energy.

[0065] In an embodiment of the present application, the remaining part of the clean energy in the first clean energy except the second clean energy and the third clean energy can be determined as the fifth clean energy, wherein, when the fifth clean energy does not exist in the first clean energy, the fourth clean energy in the storage state can be subjected to a second round of electric energy conversion, and the electric energy obtained by the second round of electric energy conversion can be determined as the second electric energy.

[0066] As an example, if the first clean energy is set to solar energy, then in the daytime scenario, the solar collector will continuously collect solar energy. Therefore, in addition to the second clean energy and the third clean energy, there may be some remaining fifth clean energy in the first clean energy. In this scenario, the fourth clean energy and the fifth clean energy can be converted into electricity for the second round to obtain the second electricity.

[0067] As another example, if the first clean energy is set to solar energy, then in a dark scene, the solar collector will stop collecting solar energy. Therefore, except for the second clean energy and the third clean energy, there may be no fifth clean energy in the first clean energy. In this scenario, the fourth clean energy in a storage state obtained by storing energy based on the third clean energy can be converted into second electric energy through a second round of conversion.

[0068] S204: Supply energy to the user cluster based on the first electric energy and the second electric energy.

[0069] Optionally, in response to identifying that the first electric energy does not meet the energy demand of the user cluster, the user cluster is supplied with energy based on the second electric energy.

[0070] In an embodiment of the present application, the current electricity demand of the user cluster can be obtained, and the demand amount carried in the demand can be determined as the energy demand of the user cluster. When it is identified that the first electric energy cannot meet the energy demand, it can be determined that energy supply based on the first electric energy may cause an abnormal situation of insufficient power supply to the user cluster. In this scenario, energy supply can be based on the second electric energy to reduce the probability of occurrence of this abnormal situation.

[0071] Optionally, in response to identifying that the first electric energy satisfies energy demand of the user cluster, energy is supplied to the user cluster based on the first electric energy.

[0072] In an embodiment of the present application, when it is identified that the first electric energy can meet the energy demand of the user cluster, it can be determined that when energy is supplied based on the first electric energy, the user cluster will not experience an abnormal situation of insufficient energy supply. In this scenario, the user cluster can be supplied with electric energy based on the first electric energy.

[0073] As an example, the energy supply scenario is set to a daytime scenario, wherein the first electric energy in the daytime scenario can meet the energy demand of the user cluster. In this example, energy supply can be performed based only on the first electric energy.

[0074] As another example, the energy supply scenario is set to a night scenario, wherein the first electric energy in the night scenario cannot meet the energy demand of the user cluster. In this example, the user cluster can be supplied with energy based on the first electric energy and the second electric energy.

[0075] Optionally, when the first electric energy meets the energy needs of the user cluster, the fourth clean energy in the storage state may not be processed, and when it is identified that the first electric energy cannot meet the energy needs of the user cluster, a second round of electric energy conversion is started to obtain the second electric energy, and then the user cluster is supplied with electric energy based on the first electric energy and the second electric energy.

[0076] Optionally, when the first electric energy meets the energy needs of the user cluster, the fourth clean energy can be converted into second electric energy, and the second electric energy can be stored. Further, when it is identified that the first electric energy cannot meet the energy needs of the user cluster, the user cluster is supplied with electric energy based on the first electric energy and the second electric energy in a stored state.

[0077] The energy storage and supply method based on clean energy proposed in the present application improves the energy utilization rate of the first clean energy by converting the first clean energy into the first electric energy and the second electric energy, stores the third clean energy based on the phase change energy storage method, reduces the complexity of clean energy storage processing, and in the scenario of energy supply based on the first electric energy and the second electric energy, reduces the probability of abnormal situation of insufficient power supply to the user cluster, improves the stability of energy supply to the user cluster, and optimizes the utilization method and utilization effect of clean energy.

[0078] This application also proposes a clean energy storage and energy supply system, which can be combined with Figure 4 understand, Figure 4 Schematic diagram of a clean energy storage and energy supply system according to an embodiment of the present application, such as Figure 4 As shown, the energy storage and energy supply system 400 based on clean energy includes an energy collection component 41, a first power generation component 42, an energy storage component 43, a second power generation component 44 and an energy supply component 45, wherein:

[0079] The energy collection component 41 is used to collect clean energy to obtain the first clean energy.

[0080] The first power generation component 42 is used to obtain the second clean energy required by the first power generation component for electric energy conversion from the first clean energy, and obtain the first electric energy output by the first power generation component based on the second clean energy.

[0081] The energy storage component 43 is used to obtain the third clean energy to be stored from the first clean energy, and perform phase change energy storage on the third clean energy to obtain the fourth clean energy stored in the energy storage component.

[0082] The second power generation component 44 is used to obtain the second electric energy output by the second power generation component based on the fourth clean energy and the fifth clean energy in response to identifying the presence of the fifth clean energy in the first clean energy in addition to the second clean energy and the third clean energy.

[0083] The energy supply component 45 is used to supply energy to the user cluster based on the first electrical energy and the second electrical energy.

[0084] In the embodiment of the present application, clean energy can be collected by the energy collection component 41, and the collected clean energy is determined as the first clean energy, wherein the energy collection component 41 can be a solar energy collection component, a wind energy collection component, a geothermal energy collection component, or other clean energy collection components, which are not specifically limited here.

[0085] like Figure 4 As shown, the first power generation component 42 can perform a first round of electric energy conversion on the second clean energy in the first clean energy, and the electric energy obtained by the first round of electric energy conversion is determined as the first electric energy, wherein the first electric energy is the output electric energy of the first power generation component 42.

[0086] Optionally, the first clean energy may include some remaining clean energy other than the second clean energy. In this scenario, Figure 4 The energy storage component 43 shown obtains part of the clean energy that needs to be stored from the first clean energy and determines it as the third clean energy in the first clean energy, and performs phase change energy storage on the third clean energy through the energy storage component 43 to obtain the clean energy in the storage state in the energy storage component 43 as the fourth clean energy.

[0087] Among them, the fourth clean energy can be thermal energy.

[0088] Further, through Figure 4The second power generation component 44 shown converts the fourth clean energy into electrical energy. In this scenario, it can be identified whether there is any remaining clean energy other than the second clean energy and the third clean energy in the first clean energy collected by the energy collection component 41, wherein the remaining clean energy can be determined as the fifth clean energy in the first clean energy.

[0089] Optionally, when the fifth clean energy is identified to exist in the first clean energy, Figure 4 The second power generation component 44 shown performs a second round of electric energy conversion on the fourth clean energy and the fifth clean energy, and determines the electric energy obtained from the second round of electric energy conversion as the second electric energy output by the second power generation component 44 .

[0090] Optionally, when it is identified that the fifth clean energy does not exist in the first clean energy, Figure 4 The second power generation component 44 shown performs a second round of electrical energy conversion on the fourth clean energy, and determines the converted electrical energy as the second electrical energy output by the second power generation component 44 .

[0091] Among them, the conversion of the fourth clean energy into electric energy can be understood in combination with the following contents:

[0092] As an example, Figure 3 As shown, it is necessary to convert the fourth clean energy stored in the 3-stacked bed phase change heat storage device into electric energy. Figure 3 In the scenario shown, part of the carbon dioxide flowing out of the 3-stacked bed phase change heat storage device flows to the 4-mixer, and part flows to the 4-mixer through the 18-valve and the 19-valve, and flows to the 5-turbine through the 4-mixer to expand and generate electricity. The expanded carbon dioxide first enters the low-pressure side of the 6-high-temperature regenerator to release heat, and then enters the low-pressure side of the 7-low-temperature regenerator to release heat. Then the carbon dioxide is divided into two parts through the 21-valve, one part enters the 9-recompressor for heating and pressure increase, and the other part enters the 10-stacked bed for heat release and cooling, and then enters the 8-main compressor for heating and pressure increase, and then enters the 7-low-temperature regenerator to absorb part of the released heat, and then the two parts of the working fluid are merged through the 20-valve, and the merged carbon dioxide enters the 6-high-temperature regenerator together to absorb the released heat, and then enters the 1-solar collector to absorb the heat from the external heat source, forming a closed loop.

[0093] Furthermore, to achieve Figure 3 The electrical energy conversion of the fourth clean energy stored in the 3-stacked bed phase change thermal storage device is shown.

[0094] like Figure 4 As shown, the energy storage and supply system 400 based on clean energy also includes Figure 4The energy supply component 45 shown in the figure can realize the power supply to the user cluster in this scenario through the energy supply component 45, wherein the power supply to the user cluster can be based on the first power and the second power, or based on the first power, which is not specifically limited here.

[0095] The energy storage and supply system based on clean energy proposed in the present application includes an energy collection component, a first power generation component, an energy storage component, a second power generation component and a power supply component, wherein the energy collection component is used to collect clean energy to obtain a first clean energy; the first power generation component is used to obtain a second clean energy required for the first power generation component to perform electric energy conversion from the first clean energy, and obtain the first electric energy output by the first power generation component based on the second clean energy; the energy storage component is used to obtain a third clean energy to be stored from the first clean energy, and perform phase change energy storage on the third clean energy to obtain a fourth clean energy stored by the energy storage component; the second power generation component is used to respond to the identification of the presence of a fifth clean energy in addition to the second clean energy and the third clean energy in the first clean energy, and obtain the second electric energy output by the second power generation component based on the fourth clean energy and the fifth clean energy; the power supply component is used to supply energy to a user cluster based on the first electric energy and the second electric energy.

Figure 5 As shown, the energy storage and energy supply system 500 based on clean energy includes an energy collection component 51, a first power generation component 52, an energy storage component 53, a second power generation component 55 and an energy supply component 55, wherein:

[0097] The energy storage component 53 is also used to perform heat exchange treatment on the first heat transfer fluid flowing out of the energy collection component 51 to replace the third clean energy carried by the first heat transfer fluid to obtain and store the fourth clean energy.

[0098] In the embodiment of the present application, a heat transfer fluid flows in the energy storage and energy supply system based on clean energy, for example, Figure 3The flowing carbon dioxide in the scenario shown can be identified as the heat transfer fluid.

[0099] Optionally, the heat transfer fluid flowing out of the energy collection component 51 can be determined as the first heat transfer fluid. In this scenario, the energy storage component 53 can realize phase change energy storage of the third clean energy in the first clean energy by performing heat exchange treatment on the first heat transfer fluid.

[0100] Among them, the first heat transfer fluid flowing out of the energy collection component 51 can be subjected to heat exchange treatment by the energy storage component 53, and the third clean energy carried in the first heat transfer fluid can be replaced into the energy storage component 53 through heat exchange treatment, thereby realizing phase change energy storage of the third clean energy by the energy storage component 53, and obtaining the fourth clean energy in a storage state in the energy storage component 53.

[0101] Optionally, the second power generation component 55 is further used for: in response to identifying that there is no fifth clean energy other than the second clean energy and the third clean energy in the first clean energy, performing a second round of electric energy conversion on the fourth clean energy to obtain second electric energy.

[0102] Optionally, the energy storage and supply system 500 based on clean energy further includes an adsorption refrigeration component 56 for absorbing heat from the second heat transfer fluid flowing in the first power generation component and the second power generation component respectively.

[0103] In the embodiment of the present application, it is necessary to refrigerate the heat transfer fluid flowing in the energy storage and supply system 500 based on clean energy to improve the operating efficiency of the first power generation component 52 and the second power generation component 54.

[0104] In this scenario, you can Figure 5 The adsorption refrigeration component 56 shown in the figure cools down the heat transfer fluid in the first power generation component 52 and the second power generation component 54, wherein the heat transfer fluid flowing in the first power generation component 52 and the second power generation component 54 can be marked as the respective second heat transfer fluid. Figure 5 The adsorption refrigeration component 56 shown absorbs heat from the second heat transfer fluids flowing in the first power generation component 52 and the second power generation component 54, respectively, thereby achieving refrigeration and temperature reduction of each second heat transfer fluid.

[0105] As an example, Figure 3 As shown, in Figure 3 In the scenario shown, the heat absorption and refrigeration and cooling of each second heat transfer fluid can be achieved through an adsorption refrigeration component consisting of 22-valve, 15-pump, 14-adsorption bed, 13-condenser, 12-liquid storage tank, 11-evaporator and 10-stacked bed.

[0106] When the adsorbent saturated with adsorption is heated by 1-solar collector, the refrigerant is desorbed from the adsorbent. When the refrigerant is desorbed, it flows to 14-adsorption bed through 22-valve and 15-pump to cool 14-adsorption bed. The adsorbent re-adsorbs the refrigerant vapor. The refrigerant vapor pressure in the system decreases, causing the evaporation of the refrigerant liquid in 11-evaporator. The refrigerant and the phase change material in the stacked bed exchange heat to complete the cold storage process.

[0107] Among them, the heating desorption process can be understood in combination with the following contents:

[0108] When the adsorbent saturated with adsorption is heated by 1-solar collector, the refrigerant is desorbed from the adsorbent, and after the pressure in the system rises to reach the condensation pressure, the refrigerant vapor is condensed into liquid in the condenser, and the condensed liquid flows into 12-liquid storage tank.

[0109] And, the adsorption refrigeration process can be understood in combination with the following:

[0110] When the refrigerant is desorbed, the 14-adsorption bed is cooled, and the adsorbent re-adsorbs the refrigerant vapor. The refrigerant vapor pressure in the system decreases, causing the evaporation of the refrigerant liquid in the 11-evaporator to absorb heat from the 10-stacked bed to achieve refrigeration. In this process, the adsorbent needs to be continuously cooled and transferred out of the adsorption heat exchanger to absorb heat. When the adsorption refrigeration process is completed, a refrigeration cycle is completed.

[0111] During the refrigeration cycle, the refrigerant is condensed by the condenser and stored in the 12-liquid storage tank.

[0112] The energy storage and supply system based on clean energy proposed in the present application realizes the conversion of the first clean energy into the first electric energy and the second electric energy through the energy storage and supply system based on clean energy, improves the energy utilization rate of the first clean energy, stores the third clean energy based on the phase change energy storage method, reduces the complexity of clean energy storage and processing, realizes the cooling and cooling of the heat transfer fluid through the adsorption refrigeration component arranged in the system, improves the power generation efficiency of the first power generation component and the second power generation component, reduces the operating load of the system, and in the scenario of power supply based on the first electric energy and the second electric energy, reduces the probability of abnormal situation of insufficient power supply in the user cluster, improves the stability of power supply of the user cluster, and optimizes the utilization method and utilization effect of clean energy.
