Description

Technical Field

[0001] This application belongs to the technical field of energy storage, and particularly relates to a core load intelligent power supply system, method, and a collaborative system of a home data center and an energy storage device. Background Art

[0002] Currently, with the rapid development of information technology, home data centers have gradually moved from concept to reality and have been widely promoted. Network Area Storage (NAS), which can be regarded as a private cloud, is a private storage device that can be placed at home or in the office. No matter where family members or colleagues are, they can read important files, precious photos, audio-visual collections, or rich application services stored in the NAS through a browser or a mobile application.

[0003] However, in the event of a sudden power outage, it may cause the read and write operations being performed by the NAS to be interrupted, and unsaved temporary data or file modifications may be lost. Important data may be damaged because it is not written to the disk in time. In addition, a sudden power outage may also lead to file system errors and risks of NAS hardware damage, such as damage to the hard disk head, motherboard, or power module. Currently, an Uninterruptible Power Supply (UPS) is commonly used to power the NAS. The UPS can seamlessly switch to the internal battery power supply when the mains power is interrupted or the voltage is abnormal, so as to avoid the occurrence of NAS failures caused by sudden power outages. However, the UPS only serves as an emergency power supply, and the battery capacity is limited. It can only maintain the NAS to continue working for a few hours after a power outage and cannot be used off-grid for a long time. Summary of the Invention

[0004] In order to solve or improve the above technical problem that the battery of the emergency power supply has limited capacity and can only maintain the short-term operation of the NAS after a power outage and cannot be used off-grid for a long time, an object of the present invention is to provide a core load intelligent power supply system.

[0005] Another object of the present invention is to provide a core load intelligent power supply method.

[0006] Another object of the present invention is to provide a collaborative system of a home data center and an energy storage device.

[0007] To achieve the above object, the first aspect of the present invention provides a core load intelligent power supply system, which includes: an energy storage device for storing and providing electrical energy; an intelligent distribution box connected to the energy storage device and the power grid respectively, for receiving and managing the electrical energy from the energy storage device and the power grid, and controlling the output of electrical energy to the electrical load. The intelligent distribution box includes: an energy management controller and a load switch control board. The load switch control board includes at least one core load switch control branch and at least one general load switch control branch. One of the core load switch control branches is used to connect to the core load, and the general load switch control branch is used to connect to the general load. The energy management controller establishes a communication link with the core load. Among them, the operation mode of the intelligent distribution box includes an intelligent power backup mode. The energy management controller is used for: in the case of detecting abnormal power supply from the power grid, entering the off-grid power supply state by supplying power through the energy storage device, and controlling the intelligent distribution box to enter the intelligent power backup mode to maintain continuous power supply to the core load connected through the core load switch control branch; in the case of detecting that the remaining power of the energy storage device drops to the first threshold, sending an orderly shutdown instruction to the core load through the communication link to make the core load shut down safely.

[0008] According to the core load intelligent power supply system provided by the present invention, it is used to coordinately regulate the power distribution of the core load and the general load, and through the intelligent distribution box, realize intelligent power distribution among the energy storage device, the power grid, the core load and the general load, aiming to give priority to meeting the power consumption requirements of the core load, and ensuring the safe shutdown of the core load before the remaining power of the energy storage device is exhausted, that is, shutting down normally according to the instruction from the energy management controller, to avoid the occurrence of abnormal downtime of the core load resulting in data loss and equipment damage. Further, this solution can also determine the low-frequency usage period of the core load according to the usage frequency of the core load or the user's historical usage habits, and perform instruction control on the core load during the low-frequency usage period to make it shut down safely or enter the sleep state, so as to maximize the backup power usage efficiency of the energy storage device without affecting the power consumption requirements of the core load.

[0009] It can be understood that this solution monitors the power consumption of the distribution box in the off-grid power supply state by the energy management controller, and gives priority to power backup for the core load, so as to ensure the normal power consumption of the core load, make the core load work and run within the maximum operating duration in the intelligent power backup mode, and complete a safe shutdown. By actively cutting off the power when the power is low, it protects the service life of the energy storage device and the data security of the core load, and only restores the power consumption quota of the general load when the power is sufficient, ensuring the reasonable utilization of power and the equipment safety of the core load.

[0010] In addition, the above technical solution provided by the present invention may also have the following additional technical features:

[0011] In any of the above technical solutions, the energy management controller is further configured to: when it detects that the remaining power of the energy storage device drops to a second threshold, control at least one ordinary load switch control branch to orderly turn off in stages according to the remaining power, so as to stop supplying power to the ordinary loads connected through the ordinary load switch control branch; wherein the second threshold is greater than the first threshold.

[0012] In this solution, the energy management controller can not only determine the first threshold for controlling the core load to complete a safe shutdown operation, but also determine the second threshold for turning off at least one ordinary load switch control branch. When it detects that the power supply from the power grid is abnormal and the intelligent distribution box is powered by the energy storage device, the remaining power in the energy storage device continuously decreases. After the remaining power of the energy storage device drops to the second threshold, it drops to the first threshold. Among them, the first threshold is designed to ensure the safe shutdown of the core load, and the second threshold is designed to increase the maximum working duration of the core load, that is, to turn off at least one ordinary load, reduce the power consumption in the intelligent power supply system of the core load except the core load, and extend the maximum working duration of the core load. By setting the first threshold and the second threshold, priority power backup is provided for the core load.

[0013] In any of the above technical solutions, the energy management controller is further configured to: when it detects that the core load connected through the core load switch control branch is in a low active time window, generate a first power-saving instruction and send it to the core load through the communication link, and the first power-saving instruction is used to instruct the core load to safely shut down or enter a deep sleep state.

[0014] It can be understood that to ensure that the core load is in a normal working state, the power consumption requirement corresponding to the core load is usually relatively high. If the core load is always kept in a high-power state, the remaining power of the energy storage device will be consumed at a faster rate than when the core load completes a safe shutdown or enters a deep sleep state during the low active time window. By controlling the core load to regularly sleep or shut down through the energy management controller, the effective utilization rate of electric energy is improved.

[0015] In any of the above technical solutions, before generating the first power-saving instruction and sending it to the core load through the communication link, it includes: determining a plurality of prediction periods; determining the historical usage parameters of the core load during the plurality of prediction periods; obtaining the power consumption threshold of the core load; and determining at least one low active time window of the core load according to the plurality of historical usage parameters and the power consumption threshold of the core load, and the historical usage parameters during the low active time window are less than the power consumption threshold of the core load.

[0016] In this solution, based on the historical usage parameters of the core load in multiple prediction periods, that is, the historical power consumption data corresponding to at least one core load stored in the energy management controller, by comparing the historical power consumption data within multiple prediction periods with the power consumption threshold of the core load, at least one low-active time window is determined. By using the user's historical usage data to determine at least one low-active time window, the low-active periods of the core load are intelligently identified, and the energy management controller is automatically triggered to send the first power-saving instruction, achieving an optimal balance between energy efficiency and operating costs and enhancing the user's personalized experience.

[0017] In any of the above technical solutions, the energy storage device further includes an energy storage battery pack and an inverter. The energy storage battery pack is connected to the intelligent distribution box through the inverter; the energy management controller is further configured to: when it is further detected that the power of the branch controlled by the general load switch continuously is lower than the preset power threshold, generate a second power-saving instruction, and the second power-saving instruction is used to adjust the inverter to enter a low-power mode or a shutdown mode.

[0018] In this solution, when the energy management controller detects that the power of the branch controlled by the general load switch continuously is lower than the preset power, it generates a second power-saving instruction and makes the inverter shut down or enter a low-power mode through the second power-saving instruction. That is, on the premise that the core load has completed the safe shutdown operation, when the power of the branch controlled by the general load switch continuously is lower than the preset power threshold, it means that multiple general loads connected to the intelligent distribution box are not consuming power. At this time, the inverter is in an idle state, and normal operation will generate a large amount of redundant power consumption. Therefore, by generating a second power-saving instruction through the energy management controller, the inverter is made to enter a low-power state or a shutdown state, reducing the power consumption of the inverter and further improving the effective utilization rate of the remaining power in the energy storage device.

[0019] In any of the above technical solutions, the safe shutdown of the core load is completed based on the communication mechanism with the energy management controller.

[0020] In this solution, the energy management controller sends a shutdown instruction to the core load through the communication mechanism and receives the feedback confirmation of the core load to ensure that the core load completes the safe shutdown operation before the remaining power of the energy storage device is consumed, ensuring the security of the data in the core load.

[0021] In any of the above technical solutions, the core load includes a home data center and a computer cluster system.

[0022] In this solution, the home data center is a miniaturized data storage and processing system deployed in a household environment, and the computer cluster is a high-performance computing device. The purpose of taking the home data center and the computer cluster system as the core loads is to allocate the maximum power consumption data to the home data center and / or the computer cluster system under the constraint conditions of meeting the power consumption requirements of the home data center and / or the computer cluster system, so as to ensure the normal operation of the home data center and / or the computer cluster system.

[0023] In any of the above technical solutions, the home data center includes a NAS network storage device.

[0024] In this solution, the Network Attached Storage (NAS) device, as the core component in the home data center, provides centralized data storage, backup, sharing, and multimedia services for home users. Through the local area network or the Internet, home users can access files, streaming media, and smart home data at any time.

[0025] In any of the above technical solutions, when the core load is a NAS network storage device, the first power-saving instruction includes: a cache data forced write instruction, a file system unmount instruction, and a hardware power-off control instruction.

[0026] In this solution, through the cache data forced write instruction, the file system unmount instruction, and the hardware power-off control instruction, the core load is safely shut down or enters the deep sleep state in the case of a low activity time window, achieving the effect of saving electric energy. Without damaging the transmitted data, the unnecessary power consumption of the core load is reduced, and at the same time, the mechanical wear is reduced while reducing the power consumption, and the hardware aging of the NAS device caused by the 7×24-hour full-speed operation of the core load is reduced.

[0027] The present invention also proposes a method for intelligent power supply of the core load, which is applied to an energy management controller. The energy management controller establishes a communication link with the core load. The method for intelligent power supply of the core load includes: in the case of detecting abnormal power supply from the power grid, powering through the energy storage device and entering the off-grid power supply state, and controlling the intelligent distribution box to enter the intelligent standby power mode to maintain the continuous power supply of the core load connected through the core load switch control branch; in the case of detecting that the remaining power of the energy storage device drops to the first threshold, sending an orderly shutdown instruction to the core load through the communication link to safely shut down the core load.

[0028] According to the core load intelligent power supply method provided by the present invention, intelligent power distribution is achieved among the energy storage device, the power grid, the core load, and the general load, aiming to give priority to meeting the power consumption requirements of the core load, and ensuring that the core load shuts down safely before the remaining power of the energy storage device is exhausted, that is, shuts down normally according to the instructions from the energy management controller, to avoid the occurrence of abnormal downtime of the core load, which may lead to data loss and equipment damage. Further, this solution can also determine the low-frequency usage period of the core load according to the usage frequency of the core load or the user's historical usage habits, and perform instruction control on the core load during the low-frequency usage period to make it shut down safely or enter the sleep state, maximizing the backup power usage efficiency of the energy storage device without affecting the power consumption requirements of the core load.

[0029] In the above technical solution, the core load intelligent power supply method further includes: when it is detected that the remaining power of the energy storage device drops to the second threshold, controlling at least one general load switch control branch to turn off orderly in stages according to the remaining power, so as to stop supplying power to the general loads connected through the general load switch control branch; where the second threshold is greater than the first threshold.

[0030] In this solution, when it is detected that the power grid power supply is abnormal and the core load and / or the general load is powered by the energy storage device, the remaining power in the energy storage device continuously decreases, and after the remaining power of the energy storage device drops to the second threshold, it drops to the first threshold. Among them, the first threshold is designed to ensure the safe shutdown of the core load, and the second threshold is designed to increase the maximum working duration of the core load, that is, turn off at least one general load, reduce the power consumption in the core load intelligent power supply system except the core load, extend the maximum working duration of the core load, and give priority backup power to the core load by setting the first threshold and the second threshold.

[0031] In the above technical solution, the core load intelligent power supply method further includes: when it is detected that the core load connected through the core load switch control branch is in the low active time window, generating a first power-saving instruction and sending it to the core load through the communication link, and the first power-saving instruction is used to instruct the core load to shut down safely or enter the deep sleep state.

[0032] In this solution, a first electrical instruction is sent to the core load to enable the core load to complete a safe shutdown or enter a deep sleep state within a low-activity time window. The first electrical instruction is sent to the core load through a communication link. The household user has the management authority to perform a safe shutdown or deep sleep on the core load, so that the energy management controller uses a preset protocol and port to send an instruction for safe shutdown or deep sleep to the core load through the communication link. Moreover, before sending the first electrical instruction to the core load through the energy management controller, it is ensured that there are no active read and write operations on the core load before the instruction sending operation can be performed, so as to avoid damage to the transmitted data within the core load. By enabling the core load to perform a safe shutdown or enter a deep sleep state in the case of a low-activity time window, the effect of saving electrical energy is further achieved, and unnecessary power consumption of the core load is reduced while ensuring that the transmitted data is not damaged.

[0033] In any of the above technical solutions, before generating the first electrical instruction and sending it to the core load through the communication link, it further includes: determining a plurality of prediction periods; determining the historical usage parameters of the core load within the plurality of prediction periods; obtaining the power consumption threshold of the core load; and determining at least one low-activity time window of the core load according to the plurality of historical usage parameters and the power consumption threshold of the core load, where the historical usage parameters within the low-activity time window are less than the power consumption threshold of the core load.

[0034] In this solution, at least one low-activity time window is determined by comparing the historical power consumption data corresponding to at least one core load stored in the energy management controller, that is, the historical usage parameters of the core load in a plurality of prediction periods, with the power consumption threshold of the core load in a plurality of prediction periods. At least one low-activity time window is determined through the user's historical usage data, the low-activity periods of the core load are intelligently identified, and the energy management controller is automatically triggered to send the first electrical instruction, realizing an optimal balance between energy efficiency and operating cost and improving the user's personalized experience.

[0035] In any of the above technical solutions, the intelligent power supply method for the core load is also used for: in the case of further detecting that the power continuously controlled by the ordinary load switch branch is lower than a preset power threshold, generating a second electrical instruction, where the second electrical instruction is used to adjust the inverter to enter a low-power mode or a shutdown mode.

[0036] In this solution, when it is detected that the power of the branch controlled by the ordinary load switch continuously drops below the preset power, a second-stage power-off instruction is generated, and the inverter is shut down or enters the low-power mode through the second-stage power-off instruction. That is, on the premise that the core load has completed the safe shutdown operation, when the power of the branch controlled by the ordinary load switch continuously drops below the preset power threshold, it means that multiple ordinary loads connected to the intelligent distribution box are not consuming power. At this time, the inverter is in an idle state, and normal operation will generate a large amount of redundant power consumption. Therefore, by generating a second-stage power-off instruction through the energy management controller, the inverter enters the low-power state or the shutdown state, reducing the power consumption of the inverter and further improving the effective utilization rate of the remaining power in the energy storage device.

[0037] The present invention also provides a collaborative system for a home data center and an energy storage device, including: the core load intelligent power supply system proposed in the first aspect of the present invention; a home data center, which is connected to the core load intelligent power supply system as a core load through the core load switch control branch.

[0038] According to the collaborative system for a home data center and an energy storage device provided by the present invention, including a home data center and a core load intelligent power supply system, through the core load intelligent power supply system, intelligent power dispatching is realized among the energy storage device, ordinary loads, and the home data center, ensuring that the power consumption requirements of the home data center are preferentially met. At the same time, the power generation utilization rate of the energy storage device is optimized, and the intelligent distribution box is dynamically adjusted to enter the intelligent standby power mode to achieve efficient, stable, and safe power management, further improving the information data security of the home data center.

[0039] Among them, since the collaborative system for a home data center and an energy storage device includes the solution of any of the above core load intelligent power supply systems, it has the beneficial effects of any of the above core load intelligent power supply systems, which will not be elaborated here.

[0040] The additional aspects and advantages of the technical solution of the present invention will become apparent in the following description section or be understood through the practice of the present invention. Description of the Drawings

[0050] Next, the technical solutions in the embodiments of the present application will be clearly described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0051] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally represents an "or" relationship between the associated objects before and after.

[0052] The following will, in conjunction with the accompanying drawings, explain in detail the core load intelligent power supply system, method, and the collaborative system of the home data center and energy storage device provided by the embodiments of the present application through specific embodiments and their application scenarios.

[0053] As Figure 1 and Figure 2 shown, this embodiment provides a core load intelligent power supply system 1000, including: an energy storage device 200 for storing and providing electrical energy; an intelligent power distribution box 100 connected to the energy storage device 200 and the power grid 300 respectively, for receiving and managing the electrical energy from the energy storage device 200 and the power grid 300, and controlling the output of electrical energy to the electrical load; the intelligent power distribution box 100 includes: an energy management controller 102 and a load switch control board 104; the load switch control board 104 includes at least one core load switch control branch 1042 and at least one general load switch control branch 1044, where one core load switch control branch 1042 is used to connect the core load 400, and the general load switch control branch 1044 is used to connect the general load 500; the energy management controller 102 establishes a communication link with the core load 400; wherein, the operation mode of the intelligent power distribution box 100 includes an intelligent backup power mode; the energy management controller 102 is configured to: in the case of detecting an abnormal power supply from the power grid 300, enter the off-grid power supply state by supplying power through the energy storage device 200, and control the intelligent power distribution box 100 to enter the intelligent backup power mode to maintain continuous power supply to the core load 400 connected through the core load switch control branch 1042; in the case of detecting that the remaining power of the energy storage device 200 drops to the first threshold, send an orderly shutdown instruction to the core load 400 through the communication link to enable the core load 400 to shut down safely.

[0054] According to the core load intelligent power supply system 1000 provided by this embodiment, the power distribution of the core load 400 and the general load 500 is coordinated and regulated. Through the intelligent power distribution box 100, intelligent power distribution is realized among the energy storage device 200, the power grid 300, the core load 400, and the general load 500, aiming to give priority to meeting the power consumption requirements of the core load 400, and ensuring that the core load 400 shuts down safely before the remaining power of the energy storage device 200 is exhausted, that is, shuts down normally according to the instruction from the energy management controller 102, and avoiding the occurrence of abnormal downtime of the core load 400 resulting in data loss and equipment damage.

[0055] Furthermore, this solution can also determine the low-frequency usage period of the core load 400 according to the usage frequency of the core load 400 or the user's historical usage habits, and perform instruction control on the core load 400 during the low-frequency usage period to make it shut down safely or enter the sleep state, maximizing the backup power usage efficiency of the energy storage device 200 without affecting the power consumption requirements of the core load 400.

[0056] Among them, the input end of the intelligent power distribution box 100 is connected to the energy storage device 200 and the power grid 300, and the output end is connected to the core load 400 and the general load 500. The electric energy of the energy storage device 200 in the intelligent power distribution system supplies power to the core load 400 and the general load 500 through the intelligent power distribution box 100, so that the electric energy in the energy storage device 200 preferentially supplies power to the core load 400 in the off-grid power supply state, ensuring the power consumption demand of the core load 400 and enabling the core load 400 to complete the safe shutdown operation before the power of the energy storage device 200 is exhausted.

[0057] Specifically, as Figure 3 shown, the intelligent power distribution box 100 includes an energy management controller 102 and a load switch control board 104. The load switch control board 104 includes a core load switch control branch 1042 electrically connected to the core load 400 and a general load switch control branch 1044 electrically connected to the general load 500. The energy management controller 102 controls the core load switch control branch 1042 and the general load switch control branch 1044 by establishing a communication link with the core load 400, thereby controlling the switches of the core load 400 and the general load 500. In addition, the energy management controller 102 can also monitor and measure each control branch of the load switch control board 104, and determine the remaining power in the energy storage device 200 and the power generation data of the energy storage device 200. The energy management controller 102 monitors the power input and power output of the intelligent power distribution box 100 to determine the power usage situation of the intelligent power distribution box 100 in the off-grid power supply state, preferentially distributes power to the core load 400, and determines the remaining power available for the core load 400 through the energy management controller 102. On this basis, the energy management controller 102 can also calculate the power required for at least one core load 400 to safely shut down, and determine a first threshold based on the power required for the core load 400 to safely shut down. Before the remaining power of the energy storage device 200 reaches the first threshold, the core load 400 can receive a shutdown instruction from the energy management controller 102 and complete a safe shutdown. The energy management controller 102 directly sends a standardized shutdown instruction to the core load 400 through the communication link with the core load 400, rather than simply cutting off the power supply, to ensure that the core load 400 executes a complete data saving process.

[0058] It can be understood that according to this solution, the energy management controller 102 monitors the power consumption of the distribution box in the off-grid power supply state, and preferentially powers the core load 400, so as to ensure the normal power consumption of the core load 400. In the intelligent power backup mode, the core load 400 operates within the maximum operating duration, and completes a safe shutdown. By actively cutting off the power when the power is low, the service life of the energy storage device 200 and the data security of the core load 400 are protected. Only when the power is sufficient, the power consumption quota of the general load 500 is restored, ensuring the reasonable utilization of power and the equipment safety of the core load 400.

[0059] Optionally, the energy storage device 200 includes a photovoltaic module 202 or other power generation devices that can obtain electrical energy in the case of abnormal power supply of the power grid 300, and can also be other new energy power generation devices. By means of the energy storage device 200, the power storage capacity of the intelligent power supply system 1000 for the core load in the off-grid power supply state is improved, so as to meet the power consumption requirements of the core load 400 and increase the maximum operating duration of the core load 400.

[0060] In some embodiments, optionally, the energy management controller 102 is further configured to: when detecting that the remaining power of the energy storage device 200 drops to a second threshold, control at least one general load switch control branch 1044 to be turned off in an orderly manner according to the remaining power, so as to stop supplying power to the general load 500 connected through the general load switch control branch 1044; wherein the second threshold is greater than the first threshold.

[0061] In this solution, the energy management controller 102 can not only determine the first threshold for controlling the core load 400 to complete a safe shutdown operation, but also determine the second threshold for turning off at least one general load switch control branch 1044. When detecting abnormal power supply of the power grid 300 and the intelligent distribution box 100 supplies power through the energy storage device 200, the remaining power in the energy storage device 200 continuously decreases. After the remaining power of the energy storage device 200 drops to the second threshold and then drops to the first threshold. Among them, the first threshold is designed to ensure the safe shutdown of the core load 400, and the second threshold is designed to increase the maximum working duration of the core load 400, that is, to turn off at least one general load 500, reduce the power consumption in the intelligent power supply system 1000 for the core load except the core load 400, and extend the maximum working duration of the core load 400. By setting the first threshold and the second threshold, the core load 400 is preferentially powered.

[0062] Among them, the second threshold can be determined by any user in the home group according to customization, or can be calculated by the energy management controller 102 based on the maximum storage power of the intelligent power distribution box 100, the power consumption of multiple ordinary loads 500, and the power consumption of at least one core load 400. When the remaining power reaches the second threshold, a power-off control signal is sent through the energy management controller 102 to sequentially cut off the control branches corresponding to multiple ordinary loads 500, aiming to enable the core load 400 to operate within the maximum operating duration.

[0063] Optionally, the energy management controller 102 determines the shutdown priority corresponding to the ordinary load 500 according to the power consumption of at least one ordinary load 500. The greater the power consumption of the ordinary load 500, the higher the shutdown priority of the corresponding ordinary load switch control branch 1044, that is, to control at least one ordinary load switch control branch 1044 to be sequentially shut down in an orderly manner according to the remaining power to preferentially turn off the high-power ordinary load 500, and sequentially turn off the high-power ordinary load 500 connected to the intelligent power supply system 1000 of the core load, further increasing the maximum operating duration of the core load 400 and improving the utilization efficiency of the remaining power in the energy storage device 200 by the core load 400.

[0064] In some embodiments, optionally, the energy management controller is further configured to: when detecting that the core load 400 connected through the core load switch control branch 1042 is in a low active time window, generate a first power-saving instruction and send it to the core load 400 through the communication link, and the first power-saving instruction is used to instruct the core load 400 to safely shut down or enter the deep sleep state.

[0065] In this solution, the intelligent power distribution box 100 can also send a first power-saving instruction to the core load 400 through the energy management controller in the intelligent backup power mode, so that the core load 400 can complete a safe shutdown or enter the deep sleep state within the low active time window. The energy management controller sends the first power-saving instruction to the core load 400 through the communication link. The energy management controller has the management authority to perform a safe shutdown or deep sleep on the core load 400, so that the energy management controller uses a preset protocol and port to send a safe shutdown or deep sleep instruction to the core load 400 through the communication link. And before sending the first power-saving instruction to the core load 400 through the energy management controller, it is ensured that there is no active read and write operation on the core load 400 before the instruction sending operation can be performed, so as to avoid data transmission damage in the core load 400. By making the core load 400 safely shut down or enter the deep sleep state in the case of a low active time window, the effect of further saving electric energy is achieved, and unnecessary power consumption of the core load 400 is reduced while ensuring that the transmitted data is not damaged.

[0066] Further, the period during which the core load 400 has a low access frequency, a small data transmission volume, or almost zero system load within a period of time is a low-activity time window. During this period, if the core load 400 is always kept in a normal working state, it will not only consume extra electric energy, but also increase the continuous operation time of electronic components such as hard disks or fans in the system, increasing mechanical wear. The continuous full-speed operation of the hardware device corresponding to the core load 400 for 7×24 hours will also accelerate hardware aging. Therefore, within the low-activity time window when the core load 400 is not in use, has a low access frequency, a small data transmission volume, or almost zero system load, making the core load 400 enter the safe shutdown or deep sleep state can reduce power consumption while reducing mechanical wear, and reduce the hardware aging caused by the continuous full-speed operation of the core load 400 for 7×24 hours.

[0067] It can be understood that to ensure the normal working state of the core load 400, the power consumption requirement corresponding to the core load 400 is usually relatively high. If the core load 400 is always kept in a high-power consumption state, the remaining power of the energy storage device 200 will be consumed at a faster speed compared to the remaining power consumption speed when the core load 400 completes a safe shutdown or enters the deep sleep state within the low-activity time window. By controlling the core load 400 to sleep or shut down regularly through the energy management controller 102, the effective utilization rate of electric energy can be improved.

[0068] Optionally, in the cluster core load 400 environment, there are situations where multiple core loads work simultaneously or multiple core loads sleep simultaneously. To avoid shutting down all nodes at the same time, an arrangement order corresponding to the response of multiple core loads 400 to the first power-saving instruction can be generated, and the energy management controller 102 sends the first power-saving instruction to multiple core loads 400 according to the arrangement order, so that at least one core load 400 is in a working state within the low-activity time window, bringing data security guarantee to users and enhancing the user experience.

[0069] In some embodiments, optionally, before generating the first power-saving instruction and sending it to the core load 400 through the communication link, it includes: determining multiple prediction periods; determining the historical usage parameters of the core load 400 within the multiple prediction periods; obtaining the power consumption threshold of the core load 400; and determining at least one low-activity time window of the core load 400 according to the multiple historical usage parameters and the power consumption threshold of the core load 400, where the historical usage parameters within the low-activity time window are less than the power consumption threshold of the core load 400.

[0070] In this solution, the low-activity time window is determined by the energy management controller 102 obtaining the historical usage parameters of the core load 400 over multiple time periods. The prediction period is the minimum usage cycle preset by the energy management controller 102, and the minimum usage cycle corresponds to the storage cycle of the core load 400, that is, the time period from the start of a new round of data storage in the core load 400 to the completion of this round of data storage in the core load 400. The purpose is to divide time into multiple intervals to facilitate the analysis of the working behavior state of the core load 400 in different time periods. The power consumption threshold of the core load 400 is the minimum power consumption data corresponding to the working states in which the core load 400 has no users, low access frequency, low data transfer volume, or almost zero system load stored in the energy management controller 102, that is, the power consumption, usage frequency, or load rate of the core load 400. When the real-time power consumption data of the core load 400 is less than the power consumption threshold of the core load 400, that is, the real-time power consumption, real-time usage frequency, and real-time load rate of the core load 400 are all less than their respective minimum power consumption data, it is determined that the core load 400 can complete a safe shutdown or enter a deep sleep state in this state, and it will not affect the user's data storage or daily use. By comparing the historical usage parameters of the core load 400 over multiple prediction periods, that is, the historical power consumption data corresponding to at least one core load 400 stored in the energy management controller 102, with the power consumption threshold of the core load 400 over multiple prediction periods, at least one low-activity time window is determined. By using the user's historical usage data to determine at least one low-activity time window, the low-activity periods of the core load 400 are intelligently identified, and the energy management controller 102 is automatically triggered to send a first power-saving instruction, achieving an optimal balance between energy efficiency and operating costs and improving the user's personalized experience.

[0071] Optionally, within the low-activity time window, when the energy management controller 102 monitors that the power consumption of the loads corresponding to multiple ordinary load switch control branches 1044 is higher than the initial threshold within a certain time period, a power-on instruction is sent to at least one core load 400 to connect the corresponding core load switch control branch 1042 to the power supply to complete the power-on. Among them, the initial threshold of the ordinary load 500 is the power consumption of the ordinary load 500 in the shutdown state or the deep sleep state. In this state, it is marked as an abnormal user usage situation by the energy management controller 102 and is not stored as historical usage parameters in the energy management controller 102.

[0072] Optionally, after the energy management controller 102 monitors that the remaining power of the energy storage device 200 has recovered to the charging threshold, it sends a startup instruction to the core load 400, so that the core load 400 can restart when the energy storage device 200 has sufficient electrical energy. Among them, when the remaining power of the energy storage device 200 is higher than the charging threshold, the energy storage device 200 can supply power to multiple core loads 400 and multiple general loads 500 at the same time.

[0073] Optionally, the prediction period is divided into fixed periods. For example, it is divided by the hour (0:00 - 1:00, 1:00 - 2:00... 23:00 - 24:00); or the prediction period is divided into dynamic periods, and the dynamic periods can be customized by the user, including periods such as the user's sleep period, work period, and work cycle.

[0074] Optionally, the power consumption threshold of the core load 400 is a dynamic threshold, which is automatically adjusted and updated according to historical data. For example, take the mean ± standard deviation of the power consumption thresholds of the core load 400 in the same period in the past 30 days, and further improve the prediction accuracy by setting the dynamic threshold.

[0075] In some embodiments, optionally, as Figure 3 shown, the energy storage device 200 further includes an energy storage battery pack 204 and an inverter 600. The energy storage battery pack 204 is connected to the intelligent distribution box 100 through the inverter 600; the energy management controller 102 is further configured to: in the case of further detecting that the power continuously passing through the general load switch control branch 1044 is lower than the preset power threshold, generate a second power-saving instruction, and the second power-saving instruction is used to adjust the inverter 600 to enter the low-power mode or the shutdown mode.

[0076] In this solution, the first end of the inverter 600 is connected to the energy storage battery pack 204 and the output end of the power grid 300, and the second end of the inverter 600 is connected to the input end of the intelligent distribution box 100. The inverter 600 is used to convert the direct current in the energy storage battery pack 204 into alternating current to supply power to the core load 400 and / or the general load 500. Among them, the energy storage battery pack 204 stores the direct current from the photovoltaic module 202 or the power grid 300. When the energy management controller 102 detects that the power passing through the general load switch control branch 1044 continuously is lower than the preset power, it generates a second power-saving instruction, and shuts down the inverter 600 or makes it enter the low-power mode through the second power-saving instruction. That is, on the premise that the core load 400 has completed the safe shutdown operation, when the power passing through the general load switch control branch 1044 continuously is lower than the preset power threshold, it means that none of the multiple general loads 500 connected to the intelligent distribution box 100 are consuming power. At this time, the inverter 600 is in an idle state, and normal operation will bring unnecessary power consumption. Therefore, by generating a second power-saving instruction through the energy management controller 102, the inverter 600 is made to enter the low-power state or the shutdown state, reducing the power consumption of the inverter 600 and further improving the effective utilization rate of the remaining power in the energy storage device 200.

[0077] Optionally, the inverter 600 is also used to convert the alternating current generated by the photovoltaic module 202 into direct current for storage in the energy storage battery pack 204. The inverter 600 has the function of bidirectional inversion. The direct current stored in the energy storage battery pack 204 is converted into alternating current through the inverter 600, and the alternating current is transmitted to the core load 400 and the general load 500 to provide electrical energy for the core load 400 and the general load 500; the alternating current output by the photovoltaic module 202 is converted into direct current through the inverter 600 and stored in the energy storage battery pack 204.

[0078] Optionally, the inverter 600 and the energy storage battery pack 204 are of an integrated structure. The input end of the integrated structure is connected to the photovoltaic module 202 and the power grid 300, and the output end of the integrated structure is connected to the intelligent distribution box 100.

[0079] Optionally, the inverter 600 improves the utilization efficiency of the power supply from the photovoltaic module 202 through the Maximum Power Point Tracking (MPPT) technology. Through the MPPT technology, the inverter 600 ensures that the intelligent distribution box 100 supplies power to the core load 400 and / or the general load 500 with the highest efficiency, so as to give priority to using photovoltaic power generation when the photovoltaic power generation is sufficient, reduce the dependence on the commercial power, and improve the power utilization efficiency of the energy storage device 200.

[0080] In some embodiments, optionally, the safe shutdown of the core load 400 is completed based on the communication mechanism with the energy management controller 102.

[0081] In this solution, an automated control process is achieved through two-way communication between the energy management controller 102 (Energy Management System, EMS) and the load devices. The EMS monitors and measures the load circuits corresponding to each core load 400 and / or general load 500. For example, it calculates the power consumption or obtains the real-time power. And it sends a shutdown command to the core load 400 through the communication mechanism to enable the core load 400 to shut down safely. The EMS sends a shutdown command to the core load 400 through the communication mechanism and receives the feedback confirmation from the core load 400 to ensure that the core load 400 completes the safe shutdown operation before the remaining power of the energy storage device 200 is consumed, ensuring the security of the data in the core load 400.

[0082] Optionally, the user can understand the power storage situation at the input end of the intelligent distribution box 100, the power output situation at the output end of the intelligent distribution box 100, the remaining power of the energy storage device 200, the power supply data of the general load 500, and the power supply data of the core load 400 through the mobile terminal interface. The communication mechanism of the energy management controller 102 is visually displayed on the user's mobile terminal interface. The user can manually output the instructions corresponding to any communication mechanism through the mobile interface to remotely control the core load 400 and / or the general load 500 to enter the safe shutdown state or the sleep state.

[0083] Optionally, by analyzing the user's remote operation habits of the load (such as manually turning off the entertainment device at 22:00 every day), a personalized power-saving strategy is automatically generated, and at least one general load 500 is regularly turned off according to the personalized power-saving strategy, reducing user operations and improving the user experience.

[0084] Optionally, the power supply priority in the energy management controller 102 is: photovoltaic module 202 > energy storage device 200 > power grid 300. In the case of sufficient sunlight, the photovoltaic module 202 is preferentially used to supply power to the core load 400 and the general load 500. In the case of insufficient sunlight and bad weather, the energy storage device 200 supplies power to the core load 400 and the general load 500; on this basis, if there is no remaining power in the system, the power grid 300 supplies power to the core load 400 and the general load 500. It can be understood that by setting the power supply priority, the user's electricity cost is reduced and the utilization efficiency of green energy is improved.

[0085] Optionally, the energy management controller 102 may preset a threshold for the electricity price of the main power grid, and obtain the electricity price of the power grid 300 in real time. When the real-time electricity price of the power grid 300 is less than the preset threshold for the electricity price of the main power grid and the power grid 300 is supplying power normally, the energy management controller 102 transmits an instruction to control the inverter 600 to switch to the power supply port of the power grid 300, and supply power to the core load 400 and / or the general load 500 through the power grid 300; when the real-time electricity price of the power grid 300 is greater than the preset threshold for the electricity price of the main power grid and the power grid 300 is supplying power normally, the energy management controller 102 transmits an instruction to control the inverter 600 to switch to the power supply port of the photovoltaic module 202, and supply power to the core load 400 and / or the general load 500 through the photovoltaic module 202.

[0086] In some embodiments, optionally, the core load 400 includes a home data center 402 and a computer cluster system 404.

[0087] In this solution, the home data center 402 is a miniaturized data storage and processing system deployed in a household environment, and usually includes other miniaturized data storage devices such as NAS, a home server, and a smart home center. A sudden power outage of the controllable load circuit corresponding to the home data center 402 may cause damage to its corresponding storage array or interruption of backup. Therefore, the core load intelligent power supply system 1000 needs to give priority to power backup for the core load 400 to ensure the normal operation of the core load 400. A computer cluster is a high-performance computing device. Among them, high-performance computing devices consume a large amount of power and have high heat dissipation requirements. The purpose of taking the home data center 402 and the computer cluster system 404 as the core load 400 is to allocate the maximum power consumption data to the home data center 402 and / or the computer cluster system 404 under the constraint conditions of meeting the power consumption requirements of the home data center 402 and / or the computer cluster system 404, so as to ensure the normal operation of the home data center 402 and / or the computer cluster system 404.

[0088] Optionally, when the real-time electricity price of the power grid 300 is greater than the preset threshold for the electricity price of the main power grid, a partial shutdown instruction is sent through the energy management controller 102 to shut down at least one high-performance computing device in the computer cluster system 404, thereby saving costs.

[0089] Optionally, the core load 400 is the main household load, that is, it needs to maintain a normal operating state during use, and abnormal power supply will cause excessive losses to users. For example, a refrigerator can be used as the core load 400.

[0090] In the above embodiment, optionally, the home data center 402 includes a NAS network storage device.

[0091] In this solution, a Network Attached Storage (NAS) device, as the core component in the home data center 402, provides centralized data storage, backup, sharing, and multimedia services for home users. Through the local area network or the Internet, home users can access files, streaming media, and smart home data at any time.

[0092] In the above embodiment, optionally, when the core load 400 is a NAS network storage device, the first-stage power-off instructions include: a cache data forced write instruction, a file system unmount instruction, and a hardware power-off control instruction.

[0093] In this solution, when the NAS is the connected core load 400, the energy management controller 102 sends the first-stage power-off instructions to the core load 400 to enable the core load 400 to complete a safe shutdown or enter a deep sleep state within the low-activity time window. Specifically, the first-stage power-off instructions include a cache data forced write instruction, a file system unmount instruction, and a hardware power-off control instruction. Among them, the NAS device will temporarily store some data in the memory cache during operation to improve read and write performance. If the power is directly cut off, the data that has not been written to the disk in the cache will be permanently lost. All cache data is synchronized to the physical hard disk through the cache data forced write instruction to ensure data integrity; to prevent sudden power-off from causing damage to the file system, the file system is safely disconnected from the operating system through the file system unmount instruction; after the data synchronization and file system unmount are completed, the EMS sends a hardware power-off instruction to control the NAS to safely cut off the power and enter the sleep or full shutdown state. Through the cache data forced write instruction, the file system unmount instruction, and the hardware power-off control instruction, the core load 400 is safely shut down or enters a deep sleep state in the case of a low-activity time window, achieving the effect of saving electric energy. Without damaging the transmitted data, unnecessary power consumption of the core load 400 is reduced, and at the same time, mechanical wear is reduced while reducing power consumption, and the hardware aging of the NAS device caused by the full-speed operation of the core load 400 within 7×24 hours is reduced.

[0094] This embodiment also provides a method for intelligent power supply to the core load, which is applied to the energy management controller. As Figure 6 shown, the method for intelligent power supply to the core load includes:

[0095] Step S100: When detecting an abnormal power supply from the power grid, switch to off-grid power supply through the energy storage device and control the intelligent power distribution box to enter the intelligent backup power mode to maintain continuous power supply to the core load connected through the core load switch control branch;

[0096] Step S102: When it is detected that the remaining power of the energy storage device drops to the first threshold, send an orderly shutdown instruction to the core load through the communication link to enable the core load to shut down safely.

[0097] The intelligent power supply method for the core load provided in this embodiment realizes intelligent power distribution among the energy storage device, the power grid, the core load, and the general load, aiming to give priority to meeting the power consumption requirements of the core load, and ensuring that the core load shuts down safely before the remaining power of the energy storage device is exhausted, that is, shutting down normally according to the instruction from the energy management controller, to avoid the occurrence of abnormal downtime of the core load, which may lead to data loss and equipment damage. Further, this solution can also determine the low-frequency usage period of the core load according to the usage frequency of the core load or the user's historical usage habits, and perform instruction control on the core load during the low-frequency usage period to make it shut down safely or enter the sleep state, so as to maximize the backup power usage efficiency of the energy storage device without affecting the power consumption requirements of the core load.

[0098] It can be understood that this solution monitors the power usage of the distribution box in the off-grid power supply state by the energy management controller, and gives priority to backup power for the core load, so as to ensure the normal power consumption of the core load. When the core load operates within the maximum operating duration, it shuts down safely. By actively cutting off the power when the power is low, it protects the service life of the energy storage device and the data security of the core load, and only restores the power consumption quota of the general load when the power is sufficient, ensuring the reasonable utilization of power and the equipment safety of the core load.

[0099] Optionally, the intelligent power supply method for the core load further includes: when it is detected that the remaining power of the energy storage device drops to the second threshold, controlling at least one general load switch control branch to be orderly shut down in stages according to the remaining power to stop supplying power to the general load connected through the general load switch control branch.

[0100] Wherein, the second threshold is greater than the first threshold.

[0101] In this embodiment, not only can the first threshold for controlling the core load to complete the safe shutdown operation be determined, but also the second threshold for shutting down at least one general load switch control branch can be determined. When it is detected that the power grid power supply is abnormal and the core load and / or the general load is powered by the energy storage device, the remaining power in the energy storage device continuously decreases. After the remaining power of the energy storage device drops to the second threshold, it drops to the first threshold. Among them, the first threshold is designed to ensure the safe shutdown of the core load, and the second threshold is designed to increase the maximum working duration of the core load, that is, to turn off at least one general load, reduce the power consumption in the intelligent power supply system of the core load except the core load, and extend the maximum working duration of the core load. By setting the first threshold and the second threshold, priority backup power is provided for the core load.

[0102] Among them, the second threshold can be determined by any user in the home group according to customization, or can be calculated by the energy management controller based on the maximum storage power of the intelligent distribution box, the power consumption of multiple ordinary loads, and the power consumption of at least one core load. When the remaining power reaches the second threshold, the energy management controller sends a power-off control signal to sequentially cut off the control branches corresponding to multiple ordinary loads, aiming to enable the core load to operate within the maximum operating duration.

[0103] Optionally, the power-off priority corresponding to the ordinary load is determined according to the power consumption of at least one ordinary load. The greater the power consumption of the ordinary load, the higher the power-off priority of the corresponding ordinary load switch control branch, that is, at least one ordinary load switch control branch is controlled to be turned off in an orderly manner according to the remaining power, and the high-power ordinary loads connected to the intelligent power supply system of the core load are turned off in sequence, further increasing the maximum operating duration of the core load and improving the utilization efficiency of the remaining power in the energy storage device by the core load.

[0104] Optionally, the intelligent power supply method for the core load further includes: when it is detected that the core load connected through the core load switch control branch is in a low active time window, generating a first power-saving instruction and sending it to the core load through the communication link, and the first power-saving instruction is used to instruct the core load to shut down safely or enter a deep sleep state.

[0105] In this embodiment, the first power-saving instruction is sent to the core load so that the core load can complete a safe shutdown or enter a deep sleep state within the low active time window. By sending the first power-saving instruction to the core load through the communication link, the home user has the management authority to perform a safe shutdown or deep sleep on the core load, so that the energy management controller can send a safe shutdown or deep sleep instruction to the core load through the communication link using a preset protocol and port. And before sending the first power-saving instruction to the core load through the energy management controller, it is ensured that there are no active read and write operations on the core load before the instruction sending operation can be performed, so as to avoid data corruption during the transmission in the core load. By enabling the core load to shut down safely or enter a deep sleep state in the case of a low active time window, the effect of further saving electric energy is achieved, and unnecessary power consumption of the core load is reduced while ensuring that the transmitted data is not damaged.

[0106] Further, the period during which the core load has a low access frequency, a small data transfer volume, or the system load is almost zero within a certain period of time is a low-activity time window. During this period, if the core load is always kept in a normal working state, it will not only consume extra electric energy, but also increase the continuous operation time of electronic components such as hard disks or fans in the system, increasing mechanical wear. The continuous full-speed operation of the hardware device corresponding to the core load for 7×24 hours will also accelerate the hardware aging. Therefore, within the low-activity time window when the core load is not in use, has a low access frequency, has a small data transfer volume, or the system load is almost zero, making the core load enter the safe shutdown or deep sleep state can reduce power consumption while reducing mechanical wear and reducing the hardware aging caused by the continuous full-speed operation of the core load for 7×24 hours.

[0107] It can be understood that to ensure the normal working state of the core load, the power consumption requirement corresponding to the core load is usually relatively high. If the core load is always kept in a high-power state, the remaining power of the energy storage device will be consumed at a faster speed compared to the remaining power consumption speed when the core load completes a safe shutdown or enters the deep sleep state within the low-activity time window. By controlling the core load to periodically sleep or periodically shut down through the energy management controller, the effective utilization rate of electric energy can be improved.

[0108] Optionally, in the cluster core load environment, there are situations where multiple core loads work simultaneously or multiple core loads sleep simultaneously. To avoid shutting down all nodes at the same time, an arrangement order corresponding to multiple core loads in response to the first power-saving instruction can be generated, and the energy management controller sends the first power-saving instruction to multiple core loads according to the arrangement order, so that at least one core load is in a working state within the low-activity time window, providing data security guarantee for users and enhancing the user experience.

[0109] Optionally, as Figure 7 shown, before generating the first power-saving instruction and sending it to the core load through the communication link, it further includes:

[0110] Step S302: Determine multiple prediction periods;

[0111] Step S304: Determine the historical usage parameters of the core load within multiple prediction periods;

[0112] Step S306: Obtain the power consumption threshold of the core load;

[0113] Step S308: Determine at least one low-activity time window of the core load according to multiple historical usage parameters and the power consumption threshold of the core load, and the historical usage parameters within the low-activity time window are less than the power consumption threshold of the core load.

[0114] In this embodiment, the low-activity time window is determined by obtaining the historical usage parameters of the core load in multiple time periods. The prediction period is the minimum usage cycle preset by the energy management controller, and the minimum usage cycle corresponds to the storage cycle of the core load, that is, the time cycle from the start of a new round of data storage of the core load to the completion of this round of data storage of the core load. The purpose is to divide the time into multiple intervals to facilitate the analysis of the working behavior state of the core load in different time periods. The power consumption threshold of the core load is the minimum power consumption data corresponding to the working states of the core load with no user usage, low access frequency, low data transfer volume, or almost zero system load stored in the energy management controller, that is, the power consumption, usage frequency, or load rate of the core load. When the real-time power consumption data of the core load is less than the power consumption threshold of the core load, that is, the real-time power consumption, real-time usage frequency, and real-time load rate of the core load are all less than their respective minimum power consumption data, it is determined that the core load can complete a safe shutdown or enter a deep sleep state in this state without affecting the user's data storage or daily use. By comparing the historical usage parameters of the core load in multiple prediction periods, that is, the historical power consumption data corresponding to at least one core load stored in the energy management controller, with the power consumption threshold of the core load through the historical power consumption data in multiple prediction periods, at least one low-activity time window is determined. By determining at least one low-activity time window through the user's historical usage data, the low-activity periods of the core load are intelligently identified, and the energy management controller is automatically triggered to send the first power-saving instruction to achieve an optimal balance between energy efficiency and operating costs and improve the user's personalized experience.

[0115] Optionally, within the low-activity time window, when it is detected that the power consumption of the loads corresponding to multiple ordinary load switch control branches is higher than the initial threshold within a certain period of time, a startup instruction is sent to at least one core load to connect the corresponding core load switch control branch to the power supply to complete startup.

[0116] Among them, the initial threshold of the ordinary load is the power consumption of the ordinary load in the shutdown state or the deep sleep state. In this state, it is marked as an abnormal user usage situation by the energy management controller and is not stored as historical usage parameters in the energy management controller.

[0117] Optionally, when the remaining power of the energy storage device is restored to the charging threshold, a startup instruction is sent to the core load so that the core load can be restarted when the energy of the energy storage device is sufficient. Among them, when the remaining power of the energy storage device is higher than the charging threshold, the energy storage device can supply power to multiple core loads and multiple ordinary loads at the same time.

[0118] Optionally, the prediction period is divided into fixed time periods. For example, it is divided by the hour (0:00 - 1:00, 1:00 - 2:00... 23:00 - 24:00); or the prediction period is divided into dynamic time periods, and the dynamic time periods can be customized by the user, including time periods such as the user's sleep period, work period, and work cycle.

[0119] Optionally, the core load power consumption threshold is a dynamic threshold, which is automatically adjusted and updated according to historical data. For example, take the mean ± standard deviation of the core load power consumption thresholds in the same time period in the past 30 days, and further improve the prediction accuracy by setting the dynamic threshold.

[0120] Optionally, the core load intelligent power supply method is also used for: in the case where it is further detected that the power of the branch controlled by the general load switch continues to be lower than the preset power threshold, generating a second power saving instruction, and the second power saving instruction is used to adjust the inverter to enter the low power consumption mode or the shutdown mode.

[0121] In this embodiment, when it is detected that the power of the branch controlled by the general load switch continues to be lower than the preset power, a second power saving instruction is generated, and the inverter is shut down or enters the low power consumption mode through the second power saving instruction. That is, on the premise that the core load has completed the safe shutdown operation, when the power of the branch controlled by the general load switch continues to be lower than the preset power threshold, it means that multiple general loads connected to the intelligent distribution box are not consuming power. At this time, the inverter is in an idle state, and normal operation will generate a large amount of redundant power consumption. Therefore, by generating a second power saving instruction through the energy management controller, the inverter is made to enter the low power consumption state or the shutdown state, reducing the power consumption of the inverter and further improving the power utilization efficiency of the remaining power in the energy storage device.

[0122] As Figure 5 shown, an embodiment of the present application provides a collaborative system 2000 for a home data center and an energy storage device, including: the core load intelligent power supply system 1000 proposed by the present invention; a home data center 402, and the home data center 402 is connected to the core load intelligent power supply system 1000 as a core load 400 through a core load switch control branch.

[0123] According to the collaborative system 2000 for a home data center and an energy storage device provided by the present invention, including a home data center 402 and a core load intelligent power supply system 1000, through the core load intelligent power supply system 1000, intelligent power scheduling is realized among the energy storage device 200, general loads 500, and home data center 402, ensuring that the power consumption requirements of the home data center 402 are preferentially met, while optimizing the power generation utilization rate of the energy storage device 200, and dynamically adjusting the intelligent distribution box 100 to enter the intelligent power backup mode to achieve efficient, stable, and safe power management, and further improving the information data security of the home data center 402.

[0124] Among them, since the home data center and the energy storage device collaborative system 2000 includes the solution of any one of the above core load intelligent power supply systems 1000, it has the beneficial effects of any one of the above core load intelligent power supply systems 1000, which will not be elaborated here.

[0125] The present application provides a specific embodiment. Both the home data center and the NAS cloud storage device are used as core loads and are connected to a household energy storage system (i.e., the core load intelligent power supply system). The household energy storage system includes: photovoltaic modules (optional), energy storage batteries (i.e., energy storage devices), inverters (the energy storage battery and the inverter can be integrated), and distribution boxes. In addition, the household energy storage system can have more functions than a UPS. For example, for intelligent power consumption, the household energy storage system has an EMS (energy management system, also known as an energy management controller) with a communication function, which can send a shutdown command to the home data center. In extreme cases, such as when the power generation of photovoltaic power and the capacitance of the battery pack are not sufficient to supply power to the home data center, before the power is exhausted, the household energy storage system can send a shutdown command to the home data center through the EMS. After receiving the shutdown command, the home data center will shut down normally, which can further protect the home data center and avoid the risk of data loss and equipment damage caused by abnormal downtime. Intelligent power saving: The power consumption of NAS cloud storage on the market is usually about 200W. However, the usage frequency of NAS cloud storage for households is relatively low. If it is turned on 7×24h, its power consumption in a week is 33.6 kWh, which is not a small amount. And if the NAS cloud storage is kept working all the time, the inverter in the energy storage system also needs to keep working, and the inverter also has power consumption. The efficiency of the inverter at low load is lower than that at full load, which will also increase additional losses.

[0126] Therefore, the present invention also conceives a solution for intelligent power saving. When the NAS cloud storage is currently in a time period with a low usage frequency, the time periods with a low usage frequency: the time period when leaving home in the morning (7:00 - 9:00) and the time period when there is no one at night (23:00 - 7:00 the next day), the time periods with a low usage frequency can also be specified according to the user's historical usage habits. At this time, the energy storage system can send a shutdown command / sleep command to the NAS cloud storage device through the EMS to make the NAS cloud storage device enter the shutdown state or the sleep state.

[0127] Furthermore, the EMS of the energy storage system can monitor and measure each controllable load circuit of the distribution box, such as measuring the power consumption. When there is power consumption in the controllable load measurement circuit connected to the home data center, and there is no power consumption in other controllable load measurement circuits, and the NAS cloud storage is currently in a time period with a relatively low usage frequency, at this time, the energy storage system can send a shutdown command to the NAS cloud storage device through the EMS to make the NAS enter the shutdown state, and at the same time, also make the inverter enter the shutdown state or the sleep state.

[0128] In this specific embodiment, as Figure 4 shown, the first end of the energy storage device 200 is connected to the power grid 300 and the photovoltaic module 202, the second end of the energy storage device 200 is connected to the intelligent distribution box 100, and the output end of the intelligent distribution box 100 is respectively connected to the home data center 402 and multiple ordinary loads 500 through controllable load circuits.

Of course, it can also be implemented by hardware, but in many cases, the former is a better implementation method.
