Description

Technical Field

[0001] The present invention relates to the technical field of optical storage systems, and in particular, to an optical storage system, a power supply method for a computer device, a power supply control device, and a medium. Background Art

[0002] For some high-performance and high-computing-power computer devices with relatively large power demands, when they are powered by connecting to the mains power, on the one hand, the high electricity cost will lead to a high computing cost, and on the other hand, it will cause an increase in the power supply pressure of the power grid and the grid loss. For the scenario where multiple high-performance and high-computing-power computer devices work simultaneously, there may be a shortage of power supply, and even power outages may occur, affecting the stable operation of the power grid.

[0003] Since the marginal cost of photovoltaic power generation is zero, it is the current development trend to use photovoltaic power generation to supply power to the above-mentioned high-performance and high-computing-power computer devices. However, the power supply of the household optical storage system is limited and the photovoltaic power generation speed is relatively slow, while the above-mentioned high-performance and high-computing-power computer devices have a large power consumption and a fast power consumption speed. When the above-mentioned high-performance and high-computing-power computer devices are directly mounted on the optical storage system, the power of the optical storage system will soon be exhausted, which will damage the optical storage system and affect the service life of the optical storage system. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0005] To this end, the first aspect of the present invention is to propose an intelligent power supply control device.

[0006] The second aspect of the present invention is to propose an optical storage system.

[0007] The third aspect of the present invention is to propose a power supply method for a computer device based on an optical storage system.

[0008] The fourth aspect of the present invention is to propose a readable storage medium.

[0009] In view of this, according to the first aspect of the present invention, an intelligent power supply control device is proposed. The intelligent power supply control device is connected between a photovoltaic energy storage system, a mains power network, and a computer device cluster, and is used to control the power supply of the photovoltaic energy storage system and the mains power network to the computer device cluster. The intelligent power supply control device includes: a dual-source input module, which is used to electrically connect to the photovoltaic energy storage system and the mains power network respectively to form a dual-source input channel. The dual-source input channel includes a storage power supply channel and a mains power supply channel; a multi-channel output module, which is respectively connected to multiple computer devices in the computer device cluster to form a multi-channel computer device power supply channel; an electrical parameter acquisition module, which is respectively connected to the dual-source input module and the multi-channel output module, and is configured to continuously acquire the remaining power of the photovoltaic energy storage system and the total working power of the computer device cluster; a mode switching module, which is configured to control the intelligent power supply control device to enter a target working mode according to the working mode instruction after obtaining the working mode instruction; the target working mode includes any one or any combination of a green power priority mode, a computing power priority mode, and a hybrid mode; an intelligent control module, which is connected to the electrical parameter acquisition module, and is configured to control the number of computer devices turned on in the computer device cluster, and / or control the conduction of the storage power supply channel and / or the mains power supply channel in the dual-source input channel based on the control strategy in the target working mode after the intelligent power supply control device enters the target working mode; wherein, the control strategy is determined based on the remaining power of the photovoltaic energy storage system and the total working power of the computer device cluster acquired by the electrical parameter acquisition module.

[0010] In this way, based on the remaining power of the photovoltaic energy storage system and the total working power of the computer device cluster, the intelligent power supply control device reasonably distributes the power supply sources of the computer device cluster and / or adjusts the working modes of the computer devices in the computer device cluster, reducing the power supply cost of the computer device cluster, reducing the damage caused by the rapid depletion of the power of the photovoltaic energy storage system, protecting the photovoltaic energy storage system, and extending the service life of the photovoltaic energy storage system.

[0011] In some technical solutions, optionally, the intelligent control module is specifically used for: after the intelligent power supply control device enters the green power priority mode, controlling the conduction of the storage power supply channel in the dual-source input channel and closing the mains power supply channel; if it is detected that the remaining power E of the photovoltaic energy storage system < E_threshold, and the total working power P of the computer device cluster > P_pv, a hierarchical power saving control strategy is generated. The hierarchical power saving control strategy includes gradually putting each computer device in the computer device cluster into the standby state or the shutdown state according to the preset priority order, where E_threshold is the power protection threshold of the photovoltaic energy storage system, and P_pv is the photovoltaic power generation power of the photovoltaic energy storage system.

[0012] In this way, when powering the computer device, the power of the optical storage system is preferentially guaranteed, preventing the power of the optical storage system from being quickly exhausted, protecting the optical storage system, and ensuring its service life.

[0013] In some technical solutions, optionally, the intelligent power supply control device further includes: a communication module, communicatively connected to each computer device in the computer device cluster, for sending a shutdown instruction or a standby instruction to the computer device cluster.

[0014] In this way, it is possible to control the shutdown of the computer device not by directly cutting off the power, but by sending an instruction to control the computer device to enter the standby state or the shutdown state, facilitating the suspension of the computing program of the computer device in advance before power-off.

[0015] In some technical solutions, optionally, the intelligent control module is further specifically configured to: after the intelligent power supply control device enters the computing power priority mode, control the energy storage power supply channel in the dual-source input channel to conduct, while closing the mains power supply channel; if it is detected that the remaining power E of the optical storage system is less than E_critical, and the total working power P of the computer device cluster is greater than P_pv, then trigger the seamless switching mechanism, control the dual-source input module to switch from being powered by the energy storage power supply channel to being powered by the mains power supply channel, and continuously monitor the remaining power E of the optical storage system; when the remaining power E of the optical storage system rises to E_recovery, trigger the seamless switching mechanism again, control the dual-source input module to switch from being powered by the mains power supply channel to being powered by the energy storage power supply channel, and continuously monitor the remaining power E of the optical storage system; where E_critical is the power emergency switching threshold of the optical storage system, E_recovery is the recharge recovery threshold of the optical storage system, and P_pv is the photovoltaic power generation power of the optical storage system.

[0016] In this way, it is ensured that multiple computer devices in the computer device cluster do not stop running, avoiding the computing interruption failure of the computer device cluster caused by power-off.

[0017] In some technical solutions, optionally, E_recovery, E_threshold, and E_critical satisfy the numerical relationship of E_recovery > E_threshold > E_critical.

[0018] In this way, when powering the computer device based on the above three thresholds, it is possible to ensure the power of the optical storage system, prevent the power of the optical storage system from being quickly exhausted, while ensuring that multiple computer devices in the computer device cluster do not stop running, avoiding the computing interruption failure of the computer device cluster caused by power-off.

[0019] In some technical solutions, optionally, the intelligent control module is further specifically configured to: after the intelligent power supply control device enters the hybrid mode, control both the energy storage power supply channel and the mains power supply channel in the dual-source input channel to be turned on; if it is detected that the remaining power E of the photovoltaic energy storage system and the total working power P of the computer device cluster satisfy the first power supply condition, control the multi-channel output module to increase the number of computer device power supply channels connected to the energy storage power supply channel and decrease the number of computer device power supply channels connected to the mains power supply channel; if it is detected that the remaining power E of the photovoltaic energy storage system and the total working power P of the computer device cluster satisfy the second power supply condition, control the multi-channel output module to decrease the number of computer device power supply channels connected to the energy storage power supply channel and increase the number of computer device power supply channels connected to the mains power supply channel.

[0020] In this way, based on the energy storage situation of the photovoltaic energy storage system and the power consumption situation of the computer device cluster, the power supply sources for each computer device are reasonably allocated, taking into account both the power of the photovoltaic energy storage system and the power supply of the computer device cluster. While protecting the photovoltaic energy storage system, the normal operation of the computer device cluster is ensured.

[0021] In some technical solutions, optionally, the intelligent control module is further specifically configured to: if it is detected that the actual working power P_re of any computer device is ≥ P_switch, control the computer device power supply channel corresponding to the computer device to be turned on with the mains power supply channel; if it is detected that the actual working power P_re of any computer device is < P_switch, control the computer device power supply channel corresponding to the computer device to be turned on with the energy storage power supply channel; where P_switch is the power supply switching threshold of the computer device.

[0022] In this way, based on the actual working power of each computer device, the power supply sources for each computer device are reasonably allocated, taking into account both the power of the photovoltaic energy storage system and the power supply of the computer device cluster. While protecting the photovoltaic energy storage system, the normal operation of the computer device cluster is ensured.

[0023] In some technical solutions, optionally, the mode switching module is further configured to: receive a mode switching instruction through a physical button on the intelligent power supply control device; or receive a mode switching instruction sent by an application program through communication with the application program.

[0024] In this way, remote operation of the intelligent power supply control device can be achieved, thereby realizing remote control of the power supply for the computer device cluster.

[0025] In some technical solutions, optionally, the intelligent control module is further configured to: control the on / off state of each computer device power supply channel based on the control strategy in the target working mode; or receive an on / off control instruction for each computer device power supply channel sent by an application program through communication with the application program.

[0026] In this way, the diversity of the on-off control of the power supply channels of the computer device is enriched, facilitating the flexible control of the number of computer devices turned on.

[0027] In some technical solutions, optionally, the energy storage power supply channel includes a photovoltaic power supply channel and a battery power supply channel. The intelligent control module is specifically configured to: after the intelligent power supply control device enters the green power priority mode or the computing power priority mode, if it detects that the total working power P of the computer device cluster satisfies P ≤ P_pv, control the photovoltaic power supply channel in the energy storage power supply channel to conduct, and close the battery power supply channel; if it detects that the total working power P of the computer device cluster satisfies P > P_pv, then control the battery power supply channel to conduct; where P_pv is the photovoltaic power generation power of the photovoltaic-storage system.

[0028] In this way, a reasonable allocation of the power supply for the computer device cluster is achieved, reducing the damage caused by the rapid depletion of the power of the photovoltaic-storage system, protecting the photovoltaic-storage system, and extending the service life of the photovoltaic-storage system.

[0029] In some technical solutions, optionally, the communication module is specifically configured to: determine the estimated shutdown time or the estimated standby time of each computer device according to the remaining power E of the photovoltaic-storage system and the total working power P of the computer device cluster; and send a timed shutdown command or a timed standby command to the computer device cluster according to the estimated shutdown time or the estimated standby time.

[0030] In this way, it is convenient for the computer device to pause running the computing program in advance before being shut down or entering the standby state, avoiding the interruption failure problem caused by directly powering off the computer device or entering the standby state, and improving the reliability of the operation of the computer device cluster.

[0032] The photovoltaic-storage system proposed by the present invention includes the intelligent power supply control device in any of the above technical solutions. Therefore, the photovoltaic-storage system proposed by the present invention has all the beneficial effects of the intelligent power supply control device in any of the above technical solutions, which will not be elaborated here.

[0033] According to the third aspect of the present invention, a power supply method for a computer device based on a photovoltaic-storage system is also proposed. This method is executed by the intelligent power supply control device in any of the technical solutions of the first aspect. The power supply method includes: collecting the remaining power of the photovoltaic-storage system and the total working power of the computer device cluster; receiving a working mode instruction and entering a target working mode; the target working mode includes any one or any combination of a green power priority mode, a computing power priority mode, and a hybrid mode; controlling the number of computer devices turned on in the computer device cluster based on the control strategy in the target working mode, and / or controlling the conduction of the energy storage power supply channel and / or the mains power supply channel in the dual-source input channel; wherein, the control strategy is determined based on the remaining power of the photovoltaic-storage system and the total working power of the computer device cluster.

[0034] In this way, based on the remaining power of the photovoltaic-storage system and the total working power of the computer device cluster, the power supply sources of the computer device cluster are reasonably allocated, and / or the working mode of the computer device cluster is adjusted, reducing the power supply cost of the computer device cluster, reducing the damage caused by the rapid depletion of the power of the photovoltaic-storage system, protecting the photovoltaic-storage system, and extending the service life of the photovoltaic-storage system.

[0035] In some technical solutions, optionally, controlling the number of computer devices turned on in the computer device cluster based on the control strategy in the target working mode, and / or controlling the conduction of the energy storage power supply channel and / or the mains power supply channel in the dual-source input channel includes: after entering the green power priority mode, controlling the conduction of the energy storage power supply channel in the dual-source input channel and closing the mains power supply channel; if it is detected that the remaining power E of the photovoltaic-storage system is less than E_threshold, and the total working power P of the computer device cluster is greater than P_pv, a hierarchical power-saving control strategy is generated. The hierarchical power-saving control strategy includes gradually putting each computer device in the computer device cluster into the standby state or the shutdown state in accordance with a preset priority order, where E_threshold is the power protection threshold of the photovoltaic-storage system and P_pv is the photovoltaic power generation power of the photovoltaic-storage system.

[0039] In some technical solutions, optionally, based on the control strategy in the target working mode, control the number of computer devices turned on in the computer device cluster, and / or control the conduction of the energy storage power supply channel and / or the mains power supply channel in the dual-source input channel. It further includes: after entering the computing power priority mode, control the conduction of the energy storage power supply channel in the dual-source input channel, while the mains power supply channel is closed; if it is detected that the remaining power E of the photovoltaic energy storage system is less than E_critical, and the total working power P of the computer device cluster is greater than P_pv, then trigger the seamless switching mechanism, control the dual-source input module to switch from being powered by the energy storage power supply channel to being powered by the mains power supply channel, and continuously monitor the remaining power E of the photovoltaic energy storage system; when the remaining power E of the photovoltaic energy storage system rises to E_recovery, trigger the seamless switching mechanism again, control the dual-source input module to switch from being powered by the mains power supply channel to being powered by the energy storage power supply channel, and continuously monitor the remaining power E of the photovoltaic energy storage system; where E_critical is the power emergency switching threshold of the photovoltaic energy storage system, E_recovery is the recharge recovery threshold of the photovoltaic energy storage system, P_pv is the photovoltaic power generation power of the photovoltaic energy storage system, and E_recovery, E_threshold, and E_critical satisfy the numerical relationship of E_recovery > E_threshold > E_critical.

[0040] In this way, while ensuring the power of the photovoltaic energy storage system and avoiding the rapid exhaustion of the power of the photovoltaic energy storage system, it can ensure that multiple computer devices in the computer device cluster do not stop running, and avoid the computing interruption failure caused by power failure of the computer device cluster.

[0041] In some technical solutions, optionally, the energy storage power supply channel includes a photovoltaic power supply channel and a battery power supply channel.

[0042] In this way, a reasonable distribution of the power supply for the computer device cluster is achieved, reducing the damage caused by the rapid exhaustion of the power of the photovoltaic energy storage system, protecting the photovoltaic energy storage system, and extending the service life of the photovoltaic energy storage system.

[0043] In some technical solutions, optionally, controlling the number of computer devices turned on in a computer device cluster based on a control strategy in a target operating mode, and / or controlling the conduction of an energy storage power supply channel and / or a mains power supply channel in a dual-source input channel, includes: after entering the hybrid mode, controlling both the energy storage power supply channel and the mains power supply channel in the dual-source input channel to conduct; if it is detected that the remaining power E of the photovoltaic energy storage system and the total operating power P of the computer device cluster satisfy a first power supply condition, controlling the multi-output module to increase the number of computer device power supply channels conducting with the energy storage power supply channel and decrease the number of computer device power supply channels conducting with the mains power supply channel; if it is detected that the remaining power E of the photovoltaic energy storage system and the total operating power P of the computer device cluster satisfy a second power supply condition, controlling the multi-output module to decrease the number of computer device power supply channels conducting with the energy storage power supply channel and increase the number of computer device power supply channels conducting with the mains power supply channel.

Detailed Embodiments

[0059] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0060] In the following description, many specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the limitations of the specific embodiments disclosed below.

[0061] In combination with Figures 1 to 7 , the optical storage system, the computer device power supply method, the power supply control device and the medium provided by the embodiments of the present application are described in detail through specific embodiments and their application scenarios.

[0062] In an embodiment of the present invention, optionally, an intelligent power supply control device is proposed. As Figure 1 and Figure 2 shown, the intelligent power supply control device 100 provided by the present invention is connected between the optical storage system 200, the mains power network 300 and the computer device cluster 400, and is used to control the optical storage system 200 and the mains power network 300 to supply power to the computer device cluster 400.

[0063] In some embodiments, the computer device cluster 400 is a computer system composed of multiple computer devices 402. The multiple computer devices 402 cooperate to jointly complete complex computing tasks, and these complex computing tasks may include computing tasks that require rich computing power resources to complete, such as deep learning model training tasks, distributed computing tasks, privacy computing tasks, big data computing tasks, blockchain computing tasks, etc.

[0064] In some embodiments, the optical storage system 200 is a household optical storage system, which is deployed in a user's home. The household optical storage system can generate electricity through photovoltaic panels and store the electricity in the energy storage battery of the energy storage system. When the user's home needs electricity, the household optical storage system can supply power to the electrical equipment in the user's home.

[0065] Specifically, as Figure 1 shown, the intelligent power supply control device 100 includes a dual-source input module 102, a multi-channel output module 104, an electrical parameter acquisition module 106, a mode switching module 108 and an intelligent control module 110.

[0066] Among them, the dual-source input module 102 is electrically connected to the optical storage system 200 and the mains power network 300 respectively to form a dual-source input channel 114, and the dual-source input channel 114 includes an energy storage power supply channel 116 and a mains power supply channel 118.

[0067] Furthermore, the multi-channel output module 104 is respectively connected to multiple computer devices 402 in the computer device cluster 400 to form a multi-channel computer device power supply channel 120.

[0068] Further, the electrical parameter acquisition module 106 is respectively connected to the dual-source input module 102 and the multi-channel output module 104. The electrical parameter acquisition module 106 is configured to continuously acquire the remaining power of the photovoltaic energy storage system 200 and the total working power of the computer device cluster 400.

[0069] Further, the mode switching module 108 is configured to, after obtaining the working mode instruction, control the intelligent power supply control device 100 to enter the target working mode according to the working mode instruction.

[0070] Among them, the target working mode includes any one or any combination of the green power priority mode, the computing power priority mode, and the hybrid mode.

[0071] Among them, in the green power priority mode, the power generated by photovoltaic power generation and the power of the battery pack of the photovoltaic energy storage system 200 are preferentially used. At the same time, the minimum power of the photovoltaic energy storage system 200 is guaranteed to avoid the rapid depletion of the power of the photovoltaic energy storage system 200, thereby affecting the battery life; the computing power priority mode preferentially guarantees the power supply of the computer device cluster 400 to avoid interruption faults caused by power failure of the computer device cluster 400; the hybrid mode takes into account the power of the photovoltaic energy storage system 200 and the power supply of the computer device cluster 400.

[0072] Further, the intelligent control module 110 is connected to both the electrical parameter acquisition module 106 and the mode switching module 108. The intelligent control module 110 is configured to, after the intelligent power supply control device 100 enters the target working mode, control the number of computer devices turned on in the computer device cluster 400 based on the control strategy in the target working mode, and / or control the energy storage power supply channel 116 and / or the mains power supply channel 118 in the dual-source input channel 114 to conduct.

[0073] Among them, the control strategy is determined based on the remaining power of the photovoltaic energy storage system 200 and the total working power of the computer device cluster 400 acquired by the electrical parameter acquisition module 106. In this way, the intelligent power supply control device 100 reasonably distributes the power supply sources of the computer device cluster 400 based on the remaining power of the photovoltaic energy storage system 200 and the total working power of the computer device cluster 400, and / or adjusts the working modes of the computer devices in the computer device cluster 400, reducing the power supply cost of the computer device cluster 400, reducing the damage caused by the rapid depletion of the power of the photovoltaic energy storage system 200, protecting the photovoltaic energy storage system 200, and extending the service life of the photovoltaic energy storage system 200.

[0074] In the actual application process, the above-mentioned intelligent power supply control device 100 can specifically be an intelligent power strip such as a special power strip for computer devices, and the above-mentioned multi-channel output module 104 can specifically be multiple sockets provided on the intelligent power strip.

[0075] In an embodiment of the present invention, optionally, the above-mentioned target working mode may specifically include a green power priority mode.

[0076] After the intelligent power supply control device 100 enters the green power priority mode, the intelligent control module 110 controls the energy storage power supply channel 116 in the dual-source input channel 114 to conduct, and controls the mains power supply channel 118 to close, so as to supply power to the computer device cluster 400 through the photovoltaic energy storage system 200. Further, the electrical parameter acquisition module 106 continuously acquires the remaining power of the photovoltaic energy storage system 200 and the total working power of the computer device cluster 400, and transmits the acquired data to the intelligent control module 110. Further, when it is detected that the remaining power E of the photovoltaic energy storage system 200 < E_threshold, and the total working power P of the computer device cluster 400 > P_pv, the intelligent control module 110 generates a hierarchical power saving control strategy, and based on the hierarchical power saving control strategy, performs power supply control on each computer device 402 in the computer device cluster 400.

[0077] Among them, the hierarchical power saving control strategy is to gradually let each computer device 402 in the computer device cluster 400 enter the standby state or the shutdown state according to the preset priority order.

[0078] Further, E_threshold is the power protection threshold of the photovoltaic energy storage system 200, and P_pv is the photovoltaic power generation power of the photovoltaic energy storage system 200. In this way, when supplying power to the computer device, the power of the photovoltaic energy storage system 200 is preferentially guaranteed, the power of the photovoltaic energy storage system 200 is prevented from being quickly consumed, the photovoltaic energy storage system 200 is protected, and the service life of the photovoltaic energy storage system 200 is guaranteed.

[0079] Among them, for the specific value of the above-mentioned power protection threshold, those skilled in the art can set it according to the actual situation, and no specific limitation is made here.

[0080] In the actual application process, the intelligent control module 110 can specifically set N preset thresholds that decrease in sequence based on the hierarchical power saving control strategy corresponding to the green power priority mode. N is the number of computer devices 402 connected to the intelligent power supply control device 100, and one preset threshold corresponds to one computer device 402. Further, the intelligent control module 110 monitors the remaining power of the photovoltaic energy storage system 200, and when the remaining power of the photovoltaic energy storage system 200 reaches each preset threshold, controls the corresponding computer device 402 to enter the standby state or the shutdown state.

[0081] For example, the N preset thresholds include a first preset threshold, a second preset threshold to an Nth preset threshold with decreasing values in sequence, and the N preset thresholds correspond to N computer devices one by one. On this basis, after the energy storage system 200 powers the computer device cluster 400, the intelligent control module 110 monitors the remaining power of the energy storage system 200 in real time, and when the remaining power reaches the first preset threshold, controls the computer device 402 corresponding to the first preset threshold to enter the standby state or the shutdown state. When the remaining power reaches the second preset threshold, controls the computer device 402 corresponding to the second preset threshold to enter the standby state or the shutdown state, and so on. When the remaining power reaches the Nth preset threshold, controls the last computer device 402 corresponding to the Nth preset threshold to enter the standby state or the shutdown state, so as to complete shutting down all computer devices or controlling all computer devices to enter the standby state. Among them, the electrical parameter acquisition module 106 can also acquire the actual working power of each computer device 402, and the preset threshold corresponding to each computer device 402 is positively correlated with the actual working power of the computer device, that is, the larger the actual working power of the computer device 402, the larger the value of the corresponding preset threshold, so as to preferentially control the computer device 402 with a large actual working power to shut down or enter the standby state.

[0082] In the actual application process, for the specific values of the above N preset thresholds, those skilled in the art can set them according to the actual situation, and no specific limitation is made here.

[0083] In an embodiment of the present invention, optionally, as Figure 1 shown, the intelligent power supply control device 100 further includes a communication module 112.

[0084] Among them, the communication module 112 is communicatively connected to each computer device 402 in the computer device cluster 400, and is used to send a shutdown instruction or a standby instruction to the computer device cluster 400, so as to control the computer device 402 to shut down not by directly powering off, but by sending an instruction to control the computer device 402 to enter the standby state or the shutdown state. It should be noted that the computer device cluster 400 is used to run complex computing tasks including deep learning model training tasks, distributed computing tasks, privacy computing tasks, big data computing tasks, and blockchain computing tasks. If the computer device cluster 400 is shut down by exhausting the power of the energy storage system or by directly powering off, there is a high possibility that the running complex computing tasks will be interrupted abnormally. However, in the embodiment of the present invention, a shutdown instruction or a standby instruction can be sent to the computer device cluster 400 before the power of the energy storage system is exhausted, so that the computer device cluster 400 can be shut down normally, and the running complex computing tasks can be stopped and the intermediate results of the computing tasks can be saved. In this way, when the power supply to the computer device cluster 400 is restored, the complex computing task can continue to run from the stopped node.

[0085] In an embodiment of the present invention, optionally, the above-mentioned target working mode may specifically include a computing power priority mode.

[0086] After the intelligent power supply control device 100 enters the computing power priority mode, the intelligent control module 110 first controls the energy storage power supply channel 116 in the dual-source input channel 114 to conduct, and controls the mains power supply channel 118 to close, so as to supply power to the computer device cluster 400 through the optical storage system 200. Further, the electrical parameter acquisition module 106 continuously acquires the remaining power of the optical storage system 200 and the total working power of the computer device cluster 400, and transmits the acquired data to the intelligent control module 110. Further, when it is detected that the remaining power E of the optical storage system 200 < E_critical, and the total working power P of the computer device cluster 400 > P_pv, the intelligent control module 110 triggers a seamless switching mechanism, controls the dual-source input module 102 to switch from being powered by the energy storage power supply channel 116 to being powered by the mains power supply channel 118, and continuously monitors the remaining power E of the optical storage system 200.

[0087] On this basis, when it is detected that the remaining power E of the photovoltaic-storage system 200 rises back to E_recovery, the intelligent control module 110 triggers the seamless switching mechanism again, controls the dual-source input module 102 to switch from being powered by the mains power supply channel 118 to being powered by the energy storage power supply channel 116, and continuously monitors the remaining power E of the photovoltaic-storage system 200. In this way, it is ensured that multiple computer devices in the computer device cluster 400 do not shut down, avoiding the computing interruption failure caused by power outage in the computer device cluster 400, and the power of the photovoltaic-storage system 200 is used as much as possible. The cost of the power of the photovoltaic-storage system 200 is lower than the price of the mains power, thereby reducing the operating cost of the computer device cluster 400.

[0088] Among them, E_critical is the power emergency switching threshold of the photovoltaic-storage system 200, E_recovery is the recharge recovery threshold of the photovoltaic-storage system 200, and P_pv is the photovoltaic power generation power of the photovoltaic-storage system 200.

[0089] For example, after switching to the mains power network 300 to supply power to the computer device cluster 400, if the remaining power of the photovoltaic-storage system 200 recovers to 20 degrees of electricity or reaches 80% of the full power, the intelligent control module 110 will switch back to the photovoltaic-storage system 200 to supply power to the computer device cluster 400.

[0090] In the actual application process, for the specific values of the above-mentioned power emergency switching threshold and recharge recovery threshold, those skilled in the art can set them according to the actual situation, and no specific limitation is made here.

[0091] In an embodiment of the present invention, optionally, E_recovery > E_threshold > E_critical.

[0092] In this way, when supplying power to the computer device based on the above three thresholds, it is possible to ensure the power of the photovoltaic-storage system 200, avoid the power of the photovoltaic-storage system 200 from being quickly consumed, and at the same time ensure that multiple computer devices in the computer device cluster 400 do not shut down, avoiding the computing interruption failure caused by power outage in the computer device cluster 400.

[0093] In an embodiment of the present invention, optionally, the above-mentioned target working mode may specifically further include a hybrid mode.

[0094] After the intelligent power supply control device 100 enters the hybrid mode, the intelligent control module 110 controls both the energy storage power supply channel 116 and the mains power supply channel 118 in the dual-source input channel 114 to be turned on, so that in the hybrid mode, part of the computer devices in the computer device cluster 400 are powered by the photovoltaic energy storage system 200, and another part of the computer devices in the computer device cluster 400 are powered by the mains power network 300. Further, the electrical parameter acquisition module 106 continuously acquires the remaining power of the photovoltaic energy storage system 200 and the total working power of the computer device cluster 400, and transmits the acquired data to the intelligent control module 110. Further, when it is detected that the remaining power E of the photovoltaic energy storage system 200 and the total working power P of the computer device cluster 400 satisfy the first power supply condition, the intelligent control module 110 controls the multi-output module 104 to increase the number of computer device power supply channels 120 that are turned on with the energy storage power supply channel 116, and decrease the number of computer device power supply channels 120 that are turned on with the mains power supply channel 118. Further, when it is detected that the remaining power E of the photovoltaic energy storage system 200 and the total working power P of the computer device cluster 400 satisfy the second power supply condition, the intelligent control module 110 controls the multi-output module 104 to decrease the number of computer device power supply channels 120 that are turned on with the energy storage power supply channel 116, and increase the number of computer device power supply channels 120 that are turned on with the mains power supply channel 118. In this way, based on the energy storage situation of the photovoltaic energy storage system 200 and the power consumption situation of the computer device cluster 400, the power supply sources of each computer device 402 are reasonably allocated, taking into account both the power of the photovoltaic energy storage system 200 and the power supply of the computer device cluster 400. While protecting the photovoltaic energy storage system 200, the normal operation of the computer device cluster 400 is ensured.

[0095] Among them, the first power supply condition is that the remaining power of the photovoltaic energy storage system 200 and the total working power of the computer device cluster 400 indicate that the photovoltaic energy storage system 200 can independently meet the power supply requirements of the computer device cluster 400; the second power supply condition is that the remaining power of the photovoltaic energy storage system 200 and the total working power of the computer device cluster 400 indicate that it is difficult for the photovoltaic energy storage system 200 to meet the power supply requirements of the computer device cluster 400 by itself, and it is necessary to rely on the mains power network 300 to supply power to the computer device cluster 400.

[0096] In an embodiment of the present invention, optionally, in the hybrid mode, the intelligent control module 110 is further specifically configured to: if it is detected that the actual working power P_re of any computer device is ≥ P_switch, control the computer device power supply channel 120 corresponding to the computer device to be turned on with the mains power supply channel 118, so as to supply power to the high-power computer device 402 through the mains power network 300; if it is detected that the actual working power P_re of any computer device is < P_switch, control the computer device power supply channel 120 corresponding to the computer device to be turned on with the energy storage power supply channel 116, so as to supply power to the low-power computer device 402 through the optical storage system 200. In this way, based on the actual working power of each computer device 402, the power supply sources of each computer device 402 are reasonably allocated, taking into account the power of the optical storage system 200 and the power supply of the computer device cluster 400. While protecting the optical storage system 200, the normal operation of the computer device cluster 400 is ensured.

[0097] Wherein, P_switch is the power supply switching threshold of the computer device. In the actual application process, for the specific value of the above power supply switching threshold, those skilled in the art can set it according to the actual situation, and no specific limitation is made here.

[0098] In an embodiment of the present invention, optionally, the mode switching module 108 can receive a mode switching instruction through the physical button on the intelligent power supply control device 100. That is, the user can manually adjust the intelligent power supply control device 100 to work in the green power priority mode, the computing power priority mode or the hybrid mode by operating the physical button on the intelligent power supply control device 100, such as a switch.

[0099] Furthermore, the intelligent power supply control device 100 can also be communicatively connected to an electronic device, specifically communicate with the application program in the electronic device. At this time, the mode switching module 108 can receive the mode switching instruction sent by the user through the application program in the electronic device, and in response to the mode switching instruction, control the intelligent power supply control device 100 to work in the green power priority mode, the computing power priority mode or the hybrid mode. In this way, remote operation of the intelligent power supply control device 100 can be realized, thereby realizing remote control of the power supply of the computer device cluster 400.

[0100] In the actual application process, the intelligent power supply control device 100 can also receive the operation instruction sent by the user through the application program in the electronic device, and adjust the on / off state of the computer device power supply channel 120 corresponding to each computer device 402 according to the operation instruction, so that the user can remotely control the number of computer devices turned on.

[0101] Further, the intelligent power supply control device 100 can also receive an operation instruction sent by a user through an application program in an electronic device, and set the power supply duration, i.e., the operation duration, of the computer device cluster 400 according to the operation instruction. For example, the user can set a working target of running the computer device cluster 400 for 10 hours on the application program of the electronic device.

[0102] In an embodiment of the present invention, optionally, the intelligent control module 110 can also control the number of computer devices turned on in the computer device cluster 400 by controlling the conduction or disconnection of the computer device power supply channels 120 corresponding to each computer device 402.

[0103] Among them, the intelligent control module 110 can specifically control the on-off state of each computer device power supply channel 120 based on the control strategy in the target working mode, so as to control the number of computer devices turned on by energizing or de-energizing the computer devices.

[0104] Further, the user can also remotely control the on-off state of the computer device power supply channels 120 corresponding to each computer device 402 through an application program in the electronic device. At this time, the intelligent control module 110 can receive the on-off control instruction of each computer device power supply channel 120 sent by the application program, and control the conduction or disconnection of the computer device power supply channels 120 corresponding to each computer device 402 based on the on-off control instruction.

[0105] In this way, the diversity of the on-off control of the computer device power supply channels is enriched, which is convenient for flexibly controlling the number of computer devices turned on.

[0106] In an embodiment of the present invention, optionally, the energy storage power supply channel 116 can specifically include a photovoltaic power supply channel and a battery power supply channel.

[0107] Among them, the photovoltaic power supply channel is connected to the photovoltaic module in the energy storage and photovoltaic system 200, and the battery power supply channel is connected to the energy storage battery in the energy storage and photovoltaic system 200.

[0108] On this basis, after the intelligent power supply control device 100 enters the green power priority mode or the computing power priority mode, when it is detected that the total working power P of the computer device cluster 400 ≤ P_pv, the intelligent control module 110 will control the photovoltaic power supply channel in the energy storage power supply channel 116 to conduct, while the battery power supply channel is closed, where P_pv is the photovoltaic power generation power of the photovoltaic energy storage system 200. That is, when the photovoltaic power generation power is greater than or equal to the total working power of the computer device cluster 400, the computer device cluster 400 is powered only by the photovoltaic modules in the photovoltaic energy storage system 200. Further, when it is detected that the total working power P of the computer device cluster 400 > P_pv, the intelligent control module 110 will control the battery power supply channel to conduct, so that when the photovoltaic power generation power is less than the total working power of the computer device cluster 400, the computer device cluster 400 is powered by both the photovoltaic modules and the energy storage battery in the photovoltaic energy storage system 200. In this way, a reasonable allocation of the power supply for the computer device cluster 400 is achieved, reducing the damage caused by the rapid depletion of the power of the photovoltaic energy storage system 200, protecting the photovoltaic energy storage system 200, and extending the service life of the photovoltaic energy storage system 200.

[0109] In an embodiment of the present invention, optionally, when sending an instruction through the communication module 112 to control the computer device to enter the shutdown state or the standby state, the communication module 112 can specifically determine the estimated shutdown time or the estimated standby time of each computer device 402 according to the remaining power E of the photovoltaic energy storage system 200 and the total working power P of the computer device cluster 400, and then send a timed shutdown instruction or a timed standby instruction to the computer device cluster 400 according to the estimated shutdown time or the estimated standby time. In this way, it is convenient for the computer device to pause running the computing program in advance before being shut down or entering the standby state, avoiding the interruption failure problem caused by directly powering off the computer device or entering the standby state, and improving the reliability of the operation of the computer device cluster 400.

[0110] It is understandable that a household photovoltaic energy storage system is usually mainly used to supply power to household electrical loads, and the household photovoltaic energy storage system can also supply power to a computer device cluster deployed by users at home. However, a computer device cluster with high performance and high computing power has a large demand for electric energy and a fast power consumption speed, while the power consumption of the household photovoltaic energy storage system is limited and the photovoltaic power generation speed is slow. The computer device cluster will quickly consume the power of the household photovoltaic energy storage system, resulting in the household photovoltaic energy storage system being unable to supply power to other electrical loads in the user's home, making it difficult for the household photovoltaic energy storage system to be used for the computing operations of computer devices. Thus, when the computer device cluster is directly connected to the photovoltaic energy storage system, the power of the photovoltaic energy storage system will be quickly exhausted. On the one hand, it will seriously affect the working time limit of the photovoltaic energy storage system. On the other hand, the computer device will shut down due to the interruption of power supply from the photovoltaic energy storage system, which may cause the operation of the computing program to malfunction and even damage the computer device.

[0111] Therefore, the present invention proposes an intelligent power supply control device 100 that can intelligently allocate power for a computer device cluster 400. Specifically, the intelligent power supply control device 100 is connected between the photovoltaic energy storage system 200 and the computer device cluster 400. The intelligent power supply control device 100 can be connected to the mains power network 300. The intelligent power supply control device 100 also has a communication function. The intelligent power supply control device 100 can collect parameters such as the remaining power of the photovoltaic energy storage system 200 and the total working power of the computer device cluster 400 in real time. The intelligent power supply control device 100 is also provided with a green power priority mode, a computing power priority mode, and a hybrid mode. When the remaining power of the photovoltaic energy storage system 200 is low and the power consumption of the computer device cluster 400 is large, the intelligent power supply control device 100 can control some or all of the computer devices in the computer device cluster 400 to enter the standby mode or directly shut down. In the computing power priority mode, when the remaining power of the photovoltaic energy storage system 200 is low and the power consumption of the computer device cluster 400 is large, the intelligent power supply control device 100 can quickly switch to the mains power network 300 to supply power to the computer device cluster 400 instead of using the photovoltaic energy storage system 200 to supply power to the computer device cluster 400. After the power of the photovoltaic energy storage system 200 recovers to a certain capacity, it will switch back to the photovoltaic energy storage system 200 to supply power to the computer device cluster 400. In the hybrid mode, the intelligent power supply control device 100 supplies power to a part of the computer devices in the computer device cluster 400 through the photovoltaic energy storage system 200 and supplies power to another part of the computer devices in the computer device cluster 400 through the mains power network 300 according to the energy storage situation of the photovoltaic energy storage system 200 and the operation situation of the computer device cluster 400.

[0112] Thus, the photovoltaic energy storage system 200 can store electricity in the energy storage battery through photovoltaic power generation, and assist the mains power grid 300 to supply power to the computer equipment cluster 400 through the energy storage battery and the photovoltaic module. In this way, on the one hand, the marginal cost of photovoltaic power generation is zero. Using photovoltaic power generation to supply power to the computer equipment cluster 400 can reduce the operation cost of the computer equipment cluster 400 and lower the computing cost. On the other hand, it reduces the power supply pressure on the mains power grid 300. Further, it can avoid the rapid depletion of the power of the photovoltaic energy storage system 200 due to the rapid power consumption of the computer equipment cluster 400, reduce the damage to the photovoltaic energy storage system 200, protect the photovoltaic energy storage system 200, and the computer equipment cluster 400 will not cause a computing interruption failure due to sudden power outage and shutdown.

[0113] In an embodiment of the present invention, optionally, a photovoltaic energy storage system is proposed.

[0114] Among them, as Figure 2 shown, the photovoltaic energy storage system 200 provided by the present invention includes a photovoltaic module 202, an energy storage battery 204, a bidirectional inverter 206, and an intelligent power supply control device 100.

[0115] Among them, the photovoltaic module 202 is used for photovoltaic power generation and can convert solar energy into direct current.

[0116] In the actual application process, the above-mentioned photovoltaic module 202 can specifically be a photovoltaic panel or a curved photovoltaic tile, and no specific limitation is made here.

[0117] Further, the energy storage battery 204 is connected to both the photovoltaic module 202 and the intelligent power supply control device 100. The energy storage battery 204 is used to store the direct current generated by the photovoltaic module 202, and the energy storage battery 204 can also be used to convert the direct current generated by the photovoltaic module 202 or the direct current stored by itself into alternating current and output it for use by other loads in the mains power grid 300 or the photovoltaic energy storage system 200.

[0118] Specifically, the core function of the energy storage battery 204 is to store electricity. Since the power generation intensity of the photovoltaic module 202 depends on the intensity of solar energy and the photovoltaic power generation is unstable, while household electrical loads or computer equipment all require a stable power supply source. Therefore, the energy storage battery 204 can play a very good role as a stable power supply adjustment medium between photovoltaic power generation and household electricity. During the operation of the photovoltaic energy storage system 200, when the photovoltaic power generation is insufficient, the power in the energy storage battery 204 can be called to supplement the power for household electrical loads or computer equipment.

[0119] Further, the bidirectional inverter 206 is connected to the photovoltaic module 202, the energy storage battery 204, the mains power grid 300, and the intelligent power supply control device 100.

[0120] Furthermore, the bidirectional inverter 206 is used to convert the direct current generated by the photovoltaic module 202 or the direct current stored in the energy storage battery 204 into alternating current and then output it. For example, it converts the direct current in the energy storage battery 204 into alternating current to supply power to household electrical loads or computer devices, or transmits the alternating current to the mains power grid 300.

[0121] Furthermore, the bidirectional inverter 206 can also convert alternating current into direct current. For example, it converts the alternating current in the mains power grid 300 into direct current and stores it in the energy storage battery 204.

[0122] That is to say, the direct current generated by the photovoltaic module 202 through photovoltaic power generation usually has three destinations: First, it is stored in the energy storage battery 204 in the form of direct current; Second, instead of being stored in the energy storage battery 204, it directly supplies power to the computer device cluster 400 or household electrical loads after the bidirectional inverter 206 converts the direct current into alternating current; Third, after the bidirectional inverter 206 converts the direct current into alternating current, it is transmitted to the mains power grid 300, that is, sells electricity to the mains power grid 300.

[0123] Furthermore, the intelligent power supply control device 100 is connected to the photovoltaic module 202, the energy storage battery 204, the mains power grid 300, and the computer device cluster 400.

[0124] Furthermore, the intelligent power supply control device 100 has multiple working modes: green power priority mode, computing power priority mode, and hybrid mode.

[0125] Among them, the green power priority mode gives priority to ensuring the power of the photovoltaic energy storage system 200 to avoid the rapid depletion of the power of the photovoltaic energy storage system 200; the computing power priority mode gives priority to ensuring the power supply of the computer device cluster 400 to avoid interruption faults caused by power outages in the computer device cluster 400; the hybrid mode takes into account both the power of the photovoltaic energy storage system 200 and the power supply of the computer device cluster 400.

[0126] Furthermore, the intelligent power supply control device 100 has a communication function. It can communicate with the EMS (Energy Manager System) module in the photovoltaic energy storage system 200 to obtain the real-time remaining power of the photovoltaic energy storage system 200 and the photovoltaic power generation power of the photovoltaic module 202. The intelligent power supply control device 100 can also communicate with the computer device cluster 400 to obtain the operating parameters of the computer device cluster 400, such as obtaining the total working power of the computer device cluster 400 and the actual working power of each computer device 402 in the computer device cluster 400.

[0127] The energy storage system 200 proposed by the present invention includes the intelligent power supply control device 100 in any of the above technical solutions. Therefore, the energy storage system 200 proposed by the present invention has all the beneficial effects of the intelligent power supply control device 100 in any of the above technical solutions, which will not be elaborated here.

[0128] In an embodiment of the present invention, optionally, a method for supplying power to a computer device based on an energy storage system is further proposed, and this method is executed by the intelligent power supply control device in any of the above embodiments. As Figure 3 shown, the method for supplying power to a computer device based on an energy storage system may specifically include the following steps 502 to 506:

[0129] Step 502, collect the remaining power of the energy storage system and the total working power of the computer device cluster;

[0130] Step 504, receive a working mode instruction and enter the target working mode;

[0131] Step 506, control the number of computer devices turned on in the computer device cluster based on the control strategy in the target working mode, and / or control the conduction of the energy storage power supply channel and / or the mains power supply channel in the dual-source input channel;

[0132] Among them, the target working mode includes any one or any combination of the green power priority mode, the computing power priority mode, and the hybrid mode; the control strategy is determined based on the remaining power of the energy storage system and the total working power of the computer device cluster.

[0133] The method for supplying power to a computer device based on an energy storage system provided by the present invention is executed by the intelligent power supply control device in any of the above embodiments.

[0134] Specifically, in the computer device power supply method based on the optical storage system provided by the present invention, the intelligent power supply control device collects the remaining power of the optical storage system and the total working power of the computer device cluster, and receives a working mode instruction to enter the target working mode. Among them, the target working mode includes any one or any combination of the green power priority mode, the computing power priority mode, and the hybrid mode. Further, the intelligent power supply control device determines the control strategy in the target working mode based on the remaining power of the optical storage system and the total working power of the computer device cluster, and based on this control strategy, controls the number of computer devices turned on in the computer device cluster, and / or controls the conduction of the energy storage power supply channel and / or the mains power supply channel in the dual-source input channel. In this way, based on the remaining power of the optical storage system and the total working power of the computer device cluster, the power supply sources of the computer device cluster are reasonably allocated, and / or the working mode of the computer device cluster is adjusted, reducing the power supply cost of the computer device cluster, reducing the damage caused by the rapid depletion of the power of the optical storage system, protecting the optical storage system, and extending the service life of the optical storage system.

[0135] In some embodiments of the present invention, optionally, as Figure 4 shown, the above step 506 may specifically include the following steps 506a and 506b:

[0136] Step 506a, after entering the green power priority mode, control the energy storage power supply channel in the dual-source input channel to conduct, while the mains power supply channel is closed;

[0137] Step 506b, if it is detected that the remaining power E of the optical storage system < E_threshold, and the total working power P of the computer device cluster > P_pv, then generate a hierarchical power saving control strategy;

[0138] Among them, the hierarchical power saving control strategy includes gradually putting each computer device in the computer device cluster into the standby state or the shutdown state in the preset priority order, E_threshold is the power protection threshold of the optical storage system, and P_pv is the photovoltaic power generation power of the optical storage system.

[0139] In this embodiment, the above-mentioned target working mode may specifically include the green power priority mode. After the intelligent power supply control device enters the green power priority mode, it controls the energy storage power supply channel in the dual-source input channel to conduct, while controlling the mains power supply channel to close, so as to supply power to the computer device cluster through the photovoltaic energy storage system. Further, the intelligent power supply control device continuously collects the remaining power of the photovoltaic energy storage system and the total working power of the computer device cluster, and generates a hierarchical power-saving control strategy when it detects that the remaining power E of the photovoltaic energy storage system is less than E_threshold and the total working power P of the computer device cluster is greater than P_pv, and based on the hierarchical power-saving control strategy, performs power supply control on each computer device in the computer device cluster.

[0140] Among them, the hierarchical power-saving control strategy is to gradually put each computer device in the computer device cluster into the standby state or the shutdown state according to the preset priority order.

[0141] Further, E_threshold is the power protection threshold of the photovoltaic energy storage system, and P_pv is the photovoltaic power generation power of the photovoltaic energy storage system. In this way, when supplying power to the computer device, the power of the photovoltaic energy storage system is preferentially guaranteed, the power of the photovoltaic energy storage system is prevented from being quickly consumed, the photovoltaic energy storage system is protected, and the service life of the photovoltaic energy storage system is guaranteed.

[0142] In some embodiments of the present invention, optionally, the above-mentioned computer device power supply method based on the photovoltaic energy storage system may specifically further include the following step 508 and step 510:

[0143] Step 508, determine the estimated shutdown time or the estimated standby time of each computer device according to the remaining power E of the photovoltaic energy storage system and the total working power P of the computer device cluster;

[0144] Step 510, send a timed shutdown instruction or a timed standby instruction to the computer device cluster according to the estimated shutdown time or the estimated standby time.

[0145] In this embodiment, the intelligent power supply control device can control the computer device to enter the shutdown state or the standby state by sending instructions. Specifically, the intelligent power supply control device can determine the estimated shutdown time or the estimated standby time of each computer device according to the remaining power E of the photovoltaic energy storage system and the total working power P of the computer device cluster, and then send a timed shutdown instruction or a timed standby instruction to the computer device cluster according to the estimated shutdown time or the estimated standby time. In this way, it is convenient for the computer device to pause the running calculation program in advance before being shut down or entering the standby state, avoiding the interruption failure problem caused by directly powering off the computer device or entering the standby state, and improving the reliability of the computer device cluster work.

[0146] In some embodiments of the present invention, optionally, asFigure 5 As shown, step 506 above may specifically include the following steps 506c to 506e:

[0147] Step 506c, after entering the computing power priority mode, control the energy storage power supply channel in the dual-source input channel to conduct, while the mains power supply channel is closed;

[0148] Step 506d, if it is detected that the remaining power E of the photovoltaic energy storage system is less than E_critical, and the total working power P of the computer device cluster is greater than P_pv, then trigger the seamless switching mechanism, control the dual-source input module to switch from being powered by the energy storage power supply channel to being powered by the mains power supply channel, and continuously monitor the remaining power E of the photovoltaic energy storage system;

[0149] Step 506e, when the remaining power E of the photovoltaic energy storage system rises to E_recovery, trigger the seamless switching mechanism again, control the dual-source input module to switch from being powered by the mains power supply channel to being powered by the energy storage power supply channel, and continuously monitor the remaining power E of the photovoltaic energy storage system;

[0150] Among them, E_critical is the power emergency switching threshold of the photovoltaic energy storage system, E_recovery is the recharge recovery threshold of the photovoltaic energy storage system, P_pv is the photovoltaic power generation power of the photovoltaic energy storage system, and E_recovery, E_threshold, and E_critical satisfy the numerical relationship of E_recovery > E_threshold > E_critical.

[0151] In this embodiment, the above target working mode may specifically include the computing power priority mode. After the intelligent power supply control device enters the computing power priority mode, first control the energy storage power supply channel in the dual-source input channel to conduct, while controlling the mains power supply channel to be closed, so as to supply power to the computer device cluster through the photovoltaic energy storage system. Further, the intelligent power supply control device continuously collects the remaining power of the photovoltaic energy storage system and the total working power of the computer device cluster, and when it is detected that the remaining power E of the photovoltaic energy storage system is less than E_critical, and the total working power P of the computer device cluster is greater than P_pv, trigger the seamless switching mechanism, control the dual-source input module to switch from being powered by the energy storage power supply channel to being powered by the mains power supply channel, and continuously monitor the remaining power E of the photovoltaic energy storage system.

[0152] On this basis, when it is monitored that the remaining power E of the photovoltaic energy storage system rises to E_recovery, the intelligent power supply control device triggers the seamless switching mechanism again, controls the dual-source input module to switch from being powered by the mains power supply channel to being powered by the energy storage power supply channel, and continuously monitors the remaining power E of the photovoltaic energy storage system. In this way, it is ensured that multiple computer devices in the computer device cluster do not stop, and the calculation interruption fault caused by power failure of the computer device cluster is avoided.

[0153] Among them, E_critical is the power emergency switching threshold of the photovoltaic energy storage system, E_recovery is the recharge recovery threshold of the photovoltaic energy storage system, and P_pv is the photovoltaic power generation power of the photovoltaic energy storage system.

[0154] Furthermore, E_recovery > E_threshold > E_critical. In this way, when powering the computer device based on the above three thresholds, it is possible to ensure the power of the photovoltaic energy storage system, avoid the rapid depletion of the power of the photovoltaic energy storage system, and at the same time ensure that multiple computer devices in the computer device cluster do not stop, and avoid the calculation interruption failure caused by power failure in the computer device cluster.

[0155] In some embodiments of the present invention, optionally, the energy storage power supply channel includes a photovoltaic power supply channel and a battery power supply channel. The steps of controlling the conduction of the energy storage power supply channel in the control dual-source input channel may specifically include step 512 and step 514 below:

[0156] Step 512, if it is detected that the total working power P of the computer device cluster ≤ P_pv, control the photovoltaic power supply channel in the energy storage power supply channel to conduct, and the battery power supply channel is closed;

[0157] Step 514, if it is detected that the total working power P of the computer device cluster > P_pv, then control the battery power supply channel to conduct.

[0158] In this embodiment, the energy storage power supply channel specifically includes a photovoltaic power supply channel and a battery power supply channel.

[0159] On this basis, after the intelligent power supply control device enters the green power priority mode or the computing power priority mode, when controlling the conduction of the energy storage power supply channel in the control dual-source input channel, specifically, when it is detected that the total working power P of the computer device cluster ≤ P_pv, control the photovoltaic power supply channel in the energy storage power supply channel to conduct, and the battery power supply channel is closed, where P_pv is the photovoltaic power generation power of the photovoltaic energy storage system. That is, when the photovoltaic power generation power is greater than or equal to the total working power of the computer device cluster, only the photovoltaic components in the photovoltaic energy storage system are used to power the computer device cluster. Furthermore, when it is detected that the total working power P of the computer device cluster > P_pv, the intelligent power supply control device will control the battery power supply channel to conduct, so that when the photovoltaic power generation power is less than the total working power of the computer device cluster, the computer device cluster is powered by both the photovoltaic components and the energy storage battery in the photovoltaic energy storage system. In this way, a reasonable distribution of the power supply source for the computer device cluster is achieved, reducing the damage caused by the rapid depletion of the power of the photovoltaic energy storage system, protecting the photovoltaic energy storage system, and extending the service life of the photovoltaic energy storage system.

[0160] In some embodiments of the present invention, optionally, as Figure 6 shown, step 506 above may specifically include the following steps 506f to 506h:

[0161] Step 506f, after entering the hybrid mode, control both the energy storage power supply channel and the mains power supply channel in the dual-source input channel to be turned on;

[0162] Step 506g, if it is detected that the remaining power E of the photovoltaic energy storage system and the total working power P of the computer device cluster satisfy the first power supply condition, control the multi-channel output module to increase the number of computer device power supply channels conducting with the energy storage power supply channel and decrease the number of computer device power supply channels conducting with the mains power supply channel;

[0163] Step 506h, if it is detected that the remaining power E of the photovoltaic energy storage system and the total working power P of the computer device cluster satisfy the second power supply condition, control the multi-channel output module to decrease the number of computer device power supply channels conducting with the energy storage power supply channel and increase the number of computer device power supply channels conducting with the mains power supply channel.

[0164] In this embodiment, the above-mentioned target working mode may specifically further include a hybrid mode. After the intelligent power supply control device enters the hybrid mode, control both the energy storage power supply channel and the mains power supply channel in the dual-source input channel to be turned on, so that in the hybrid mode, part of the computer devices in the computer device cluster are powered by the photovoltaic energy storage system, and another part of the computer devices in the computer device cluster are powered by the mains power grid. Further, the intelligent power supply control device continuously collects the remaining power of the photovoltaic energy storage system and the total working power of the computer device cluster, and when it is detected that the remaining power E of the photovoltaic energy storage system and the total working power P of the computer device cluster satisfy the first power supply condition, increase the number of computer device power supply channels conducting with the energy storage power supply channel and decrease the number of computer device power supply channels conducting with the mains power supply channel. Further, when it is detected that the remaining power E of the photovoltaic energy storage system and the total working power P of the computer device cluster satisfy the second power supply condition, the intelligent power supply control device decreases the number of computer device power supply channels conducting with the energy storage power supply channel and increases the number of computer device power supply channels conducting with the mains power supply channel. In this way, based on the energy storage situation of the photovoltaic energy storage system and the power consumption situation of the computer device cluster, the power supply sources for each computer device are reasonably allocated, taking into account both the power of the photovoltaic energy storage system and the power supply of the computer device cluster, protecting the photovoltaic energy storage system while ensuring the normal operation of the computer device cluster.

[0165] Among them, the first power supply condition is that the remaining power of the photovoltaic and energy storage system and the total working power of the computer device cluster indicate that the photovoltaic and energy storage system can independently meet the power supply requirements of the computer device cluster; the second power supply condition is that the remaining power of the photovoltaic and energy storage system and the total working power of the computer device cluster indicate that it is difficult for the photovoltaic and energy storage system to meet the power supply requirements of the computer device cluster by itself, and it is necessary to rely on the mains power network to supply power to the computer device cluster.

[0166] In some embodiments of the present invention, optionally, as Figure 7 shown, after the above step 506f, the computer device power supply method based on the photovoltaic and energy storage system may specifically further include the following steps 516 and 518:

[0167] Step 516, if it is detected that the actual working power P_re of any computer device is ≥ P_switch, control the computer device power supply channel corresponding to the computer device to conduct with the mains power supply channel;

[0168] Step 518, if it is detected that the actual working power P_re of any computer device is < P_switch, control the computer device power supply channel corresponding to the computer device to conduct with the energy storage power supply channel;

[0169] Among them, P_switch is the power supply switching threshold of the computer device.

[0170] In this embodiment, in the hybrid mode, if it is detected that the actual working power P_re of any computer device is ≥ P_switch, the intelligent power supply control device controls the computer device power supply channel corresponding to the computer device to conduct with the mains power supply channel to supply power to the high-power computer device through the mains power network; if it is detected that the actual working power P_re of any computer device is < P_switch, the intelligent power supply control device controls the computer device power supply channel corresponding to the computer device to conduct with the energy storage power supply channel to supply power to the low-power computer device through the photovoltaic and energy storage system. In this way, based on the actual working power of each computer device, the power supply sources of each computer device are reasonably allocated, taking into account the power of the photovoltaic and energy storage system and the power supply of the computer device cluster, protecting the photovoltaic and energy storage system while ensuring the normal operation of the computer device cluster.

[0171] Among them, P_switch is the power supply switching threshold of the computer device.
