[0002] When building a data center, the relevant technology calculates capacity and configures equipment according to the maximum power demand of the cabinet (i.e., the power required at the maximum load point). This approach leads to high construction costs and a long construction payback period for the data center. In addition, since the load rate of the data center is low most of the time, the system energy efficiency is low, and the power utilization efficiency (i.e., the ratio of input power to output load power) is high, which is not conducive to energy conservation and emission reduction and control of operating costs. Summary of the invention

[0047] With the rapid development of science and technology, data centers can be applied to artificial intelligence, cloud computing and big data, the Internet of Things, smart cities, financial technology and other fields. When building a data center, the relevant technology calculates the capacity and configures the equipment according to the maximum power demand of the cabinet (that is, the power required at the maximum load point). This method leads to high construction costs and a long construction payback period for the data center. In addition, since the load rate of the data center is low most of the time, the system energy efficiency is low, and the power efficiency (that is, the ratio of input power to output load power) is high, which is not conducive to energy conservation and emission reduction and the control of operating costs.

[0048] In response to the above technical problems, this application provides a power distribution method, the idea of ​​which is to obtain the load power of the data center, which helps to dynamically optimize the power distribution plan of the data center and improve the flexibility of the power distribution method. At least based on the load power of the data center, the power distribution plan of the data center is determined and executed, which can effectively reduce the power use efficiency and improve the energy efficiency of the power distribution system, thereby reducing the operating cost of the data center and achieving better energy saving and emission reduction effects.

[0049] The embodiments provided in this application are described in detail below in conjunction with the accompanying drawings.

[0050] The power distribution method provided in this application can be applied to Figure 1 In the power distribution system shown, the power distribution system is connected between the data center and the power supply system, and is used to distribute electrical energy to the data center.

[0051] Data centers are used to centrally store, manage and operate a large number of information technology (IT) hardware devices, network devices, storage systems and related components, and are capable of transmitting, calculating, displaying and storing information.

[0068] Exemplarily, at least one battery management system is responsible for ensuring safe, efficient and reliable operation of the energy storage battery.

[0069] In some embodiments, the PCS can control the charging and discharging process of the energy storage device and is responsible for realizing the bidirectional conversion between direct current and alternating current, so that the energy storage device can directly power the data center.

A person of ordinary skill in the art can know that with the evolution of the system architecture, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0086] See also Figure 2 , is a flow chart of a power distribution method provided in an embodiment of the present application. Figure 2 As shown, the power distribution method provided in the present application is applied to a controller in a power distribution system. The power distribution system is connected between a data center and a power supply system. The power distribution system also includes energy storage equipment and UPS equipment, and specifically includes the following steps S201 to S203.

[0087] S201. Obtain the load power of the data center.

[0088] The load power of the data center refers to the sum of the powers of at least one load currently included in the data center.

[0089] Exemplarily, the load power (Pit) may be IT load power, where the IT load power includes the power of IT devices such as servers, storage devices, and network devices.

[0090] For example, in a general computing center, when the load is a single cabinet, the power of the single cabinet is greater than or equal to 4 kilowatts and less than or equal to 12 kilowatts. For example, the power of the single cabinet is 8 kilowatts.

[0091] For example, in the intelligent computing center, when the load is a single cabinet, the power of the single cabinet is greater than or equal to 20 kilowatts and less than or equal to 60 kilowatts.

[0092] S202: Determine a power distribution plan for the data center based at least on the load power of the data center.

[0093] Among them, the power distribution plan includes providing power to the data center based on one or more of the power supply system, energy storage equipment, and UPS equipment.

[0094] As a possible implementation method, the power distribution plan of the data center is determined based on the load power of the data center. The specific implementation steps refer to the following method 1 and are not described in detail here.

[0095] As another possible implementation, the above step S202 can be implemented as follows: based on the load power of the data center, the state of the power supply system, and the remaining power of the energy storage device, determine the power distribution plan of the data center. Exemplarily, based on the load power of the data center, the state of the power supply system, and the remaining power of the energy storage device, determine the power distribution plan of the data center. The specific implementation steps refer to the following method 2, which will not be repeated here.

[0096] S203: Execute the power distribution plan.

[0097] Exemplarily, the controller schedules one or more of a power supply system, an energy storage device, and a UPS device to provide power to the data center based on a configuration plan.

[0098] It can be understood that the power distribution method provided in the present application can dynamically adjust the power distribution scheme of the data center based on the load power of the data center, thereby improving the flexibility of the power distribution method. In this way, the power distribution scheme adopted by the data center can effectively reduce the power supply utilization efficiency and improve the energy efficiency of the power distribution system, thereby reducing the operating costs of the data center and achieving better energy conservation and emission reduction effects.

[0099] In some embodiments, the above step S202 can be implemented in the following manner.

[0100] Method 1: Determine the power distribution plan of the data center based on the load power of the data center.

[0101] As a possible approach, when the load power of the data center is greater than or equal to the preset power, the power distribution plan is determined as: powering the data center based on at least two of the power supply system, energy storage equipment, and UPS equipment.

[0102] For example, the preset power (Pitln) is the maximum load power set during the construction phase of the data center based on multiple factors such as business needs, equipment characteristics, energy consumption indicators, and economic benefits.

[0103] It is understandable that when the load power of the data center is greater than or equal to the preset power, a single power supply system, energy storage device or UPS device cannot maintain the normal operation of the data center load, and at least two items are required to smooth the fluctuations in load power.

[0104] Exemplarily, the fluctuation of load power generally changes with the development of data center business. For example, as the number of users of the data center increases and the amount of data grows, the load power will increase accordingly.

[0105] It should be noted that when the load power is large, the data center needs to consume more electricity during operation. If the power supply is insufficient, the load in the data center may not be able to operate normally. Therefore, at least two of the power supply system, energy storage equipment, and UPS equipment are required to power the data center.

[0106] As another possible approach, when the load power of the data center is less than a preset power, the power distribution plan is determined as: powering the data center based on any one of a power supply system, an energy storage device, and a UPS device.

[0107] It is understandable that when the load power of the data center is less than the preset power, a single power supply system, energy storage device or UPS device can maintain the normal operation of the data center load.

[0108] It can be seen from the above scheme that the power distribution method provided in the embodiment of the present application can dynamically adjust the power distribution scheme based on the load power of the data center, thereby improving the flexibility and energy efficiency of the power distribution system and reducing the power utilization efficiency (i.e., the ratio of input power to output load power). In this way, it can reduce operating costs and achieve better energy conservation and emission reduction effects.

[0109] Method 2: Determine the power distribution plan of the data center based on the load power of the data center, the status of the power supply system and the remaining power of the energy storage device.

[0110] Exemplarily, the state of the power supply system includes a normal state and an abnormal state.

[0111] Exemplarily, when the power supply system is in a normal state, the power supply system can provide stable power to the data center.

[0112] It is understandable that the power supply system under normal conditions has stable voltage and frequency, high power factor, and can provide power continuously.

[0113] Exemplarily, when the power supply system is in an abnormal state, the power supply system cannot supply power to the data center. For example, the abnormal state includes: the power supply system to the data center is interrupted, and the electric energy provided by the power supply system to the data center fluctuates greatly.

[0114] Exemplarily, the remaining power of the energy storage device is the ratio of the electric energy currently stored in the energy storage device to the maximum storage capacity of the energy storage device. Exemplarily, the remaining power of the energy storage device can be reflected by the state of charge (SOC) of the energy storage device.

[0115] As a possible implementation, see Figure 3 The above method 2 can be specifically implemented as the following steps S2021 to S2025:

[0116] S2021. When the power supply system is in a normal state, determine whether the load power of the data center is greater than or equal to a preset power.

[0117] Exemplarily, the preset power can be determined based on the rated power of the original load of the data center, for example, the preset power is less than or equal to the sum of the rated power of the original load. The rated power of the load refers to the maximum power that the load can withstand during normal operation. The original load of the data center refers to the load included in the design and assembly of the data center.

[0118] It is understandable that the electric energy provided by the power supply system is determined based on the preset power of the load of the data center to ensure that the power supply system can provide sufficient power to the load and meet the demand of the load when the load operates normally.

[0119] S2022. When the load power of the data center is less than the preset power, determine a power distribution plan to supply power to the data center based on the power supply system.

[0120] It is understandable that when the load power of the data center is less than the preset power, the electric energy provided by the power supply system can meet the electric energy demand of the load, that is, the power supply system can maintain the normal operation of the data center, and there is no need to add power supply equipment to power the data center.

[0121] Optionally, when the load power of the data center is less than a preset power and the residual current of the energy storage device is less than a preset threshold, the power supply system is controlled to charge the energy storage device.

[0122] S2023. When the load power of the data center is greater than or equal to a preset power, determine whether the remaining power of the energy storage device is greater than or equal to a preset threshold.

[0123] It is understandable that as the business data and load equipment of the data center increase, the load power of the data center will continue to increase, and the load power of the data center may be greater than or equal to the preset power. When the load power is greater than or equal to the preset power, the power provided by the power supply system cannot fully meet the power demand of the load, that is, the power supply system cannot maintain the normal operation of the data center. Therefore, it is necessary to increase power supply equipment to supply power to the data center to meet the power demand of the load.

[0124] In some embodiments, the preset threshold is the minimum value of the remaining power of the energy storage device.

[0125] Exemplarily, the preset threshold (SOC1min) is determined by the capacity of the energy storage battery in the energy storage device. When the remaining stored electrical energy in the energy storage battery is the same, the energy storage battery with a larger storage capacity has a lower remaining power. For example, the energy storage battery with a larger storage capacity has a smaller preset threshold.

[0126] It is understandable that by setting a preset threshold, the energy storage device can be prevented from being in a low-power state for a long time, thereby effectively extending the life of the energy storage device. At the same time, continuous discharge when the remaining power of the energy storage device is too low may cause the energy storage battery in the energy storage device to be damaged due to excessive discharge.

[0127] S2024. When the remaining power of the energy storage device is greater than or equal to a preset threshold, determine the power distribution plan as follows: in the first power supply stage, power the data center based on the power supply system and UPS equipment; in the second power supply stage, power the data center based on the power supply system and energy storage equipment.

[0128] The duration of the first power supply stage (Tf2) is greater than or equal to the startup duration (Tf2max) of the energy storage device. Exemplarily, the startup duration of the energy storage device is the time required for the energy storage device to receive the startup instruction and the energy storage device to stably output power. For example, the startup duration of the energy storage device is 80 milliseconds.

[0129] Exemplarily, in the first power supply stage, UPS equipment is added to provide power to the data center to maintain stable operation of the data center load.

[0130] It is understandable that in order to meet the power demand required by the load of the data center, it is necessary to increase power supply equipment to power the data center. However, since the energy storage device has a certain startup time, the present application uses a power supply system and a UPS device to power the data center in the first power supply stage; wherein, the duration of the first power supply stage is the startup duration of the energy storage device; in the second power supply stage, the power supply system and the energy storage device are used to power the data center; in this way, during the startup of the energy storage device, the UPS device (the startup time of the UPS device is shorter) can first power the data center, and then switch after the energy storage device is started, so as to maintain uninterrupted power supply to the data center.

[0131] Illustratively, in the second power supply stage, the UPS device stops supplying power, and the data center is powered by the added energy storage device to maintain stable operation of the data center load.

[0132] It is understandable that the UPS device serves as a backup power source in the power distribution system, so that under abnormal conditions, the UPS device can provide power to the data center in a timely manner. In the second power supply stage, after the energy storage device is able to provide stable power supply to the data center, the energy storage device and the power supply system are used to power the data center, and the UPS device stops supplying power.

[0133] In some embodiments, the above method further includes: in the second power supply stage, controlling the power supply system to charge the UPS device.

[0134] It is understandable that as a backup power supply, the UPS device needs to ensure that it maintains sufficient power so that it can supply power to the data center when the power supply system is abnormal. Therefore, in the second power supply stage, the power supply system charges the UPS device while supplying power to the data center.

[0135] S2025. When the remaining power of the energy storage device is less than a preset threshold, determine a power distribution plan to supply power to the data center based on the power supply system and UPS equipment.

[0136] It is understandable that the preset threshold is the minimum value of the remaining power of the energy storage device. When the remaining power of the energy storage device is less than the preset threshold, the energy storage device cannot continue to supply power to the data center. However, since the load power of the data center is greater than the preset power, the power supply system cannot maintain the stable operation of the data center alone. Therefore, it is necessary to add UPS equipment to power the data center.

[0137] In some embodiments, the above method also includes: controlling the power supply system to charge the energy storage device.

[0138] It can be understood that when the remaining power of the energy storage device is less than a preset threshold, the power supply system is controlled to charge the energy storage device to prevent the energy storage device from being in a low-power state for a long time, effectively extending the service life of the energy storage device. Controlling the power supply system to charge the energy storage device can also start the energy storage device to power the data center when the power supply system is in an abnormal state.

[0139] As another possible approach, the power distribution system also includes diesel generator sets, see Figure 4 The above method 2 can be specifically implemented as the following steps S2026-S2027:

[0140] S2026. When the power supply device is in an abnormal state and the data center is currently powered by a UPS device, determine whether the remaining power of the energy storage device is greater than or equal to a preset threshold.

[0141] It is understandable that the power supply system is in an abnormal state and cannot provide stable electricity to the data center. Backup energy storage equipment is needed to power the data center. Therefore, the power distribution plan needs to be determined based on the remaining power of the energy storage equipment.

[0142] S2027. When the remaining power of the energy storage device is greater than or equal to a preset threshold, determining a power distribution plan includes: in a first power supply stage, powering the data center based on the UPS device; and in a second power supply stage, powering the data center based on the energy storage device.

[0143] The duration of the first power supply stage is greater than or equal to the startup duration of the energy storage device.

[0144] Exemplarily, since the startup time of the UPS device is very short and almost negligible, based on this, the first power supply stage provides power to the data center based on the UPS device.

[0145] It is understandable that in the case where the power supply equipment cannot supply power to the data center, in order to meet the power required by the data center load, the power supply equipment is required to supply power to the data center. Since the energy storage device has a certain startup time, the UPS device is used to supply power to the data center in the first power supply stage, wherein the duration of the first power supply stage is the startup time of the energy storage device; in the second power supply stage, the energy storage device is used to supply power to the data center; in this way, during the startup of the energy storage device, the UPS device (the startup time of the UPS device is shorter) can first supply power to the data center, and then switch after the energy storage device is started, so as to maintain uninterrupted power supply to the data center.

[0146] In some embodiments, the above method further includes: in the second power supply stage, continuously detecting the remaining power of the energy storage device.

[0147] It should be noted that continuously detecting the remaining power of the energy storage device and avoiding continuous discharge of the energy storage device when the remaining power is too low can help extend the life of the energy storage device.

[0148] In some embodiments, when it is detected that the remaining power of the energy storage device is less than a preset threshold, the diesel generator set is controlled to start to supply power to the data center.

[0149] S2028. When the remaining power of the energy storage device is less than a preset threshold, determining a power distribution plan includes: in a first power supply stage, powering the data center based on a UPS device; in a second power supply stage, powering the data center based on a diesel generator set.

[0150] The duration of the first power supply stage is greater than or equal to the start-up time of the diesel generator set. Exemplarily, the start-up time of the diesel generator set is the time required for the diesel generator set to receive the start-up command and the diesel generator set to stably output power, for example, the start-up time of the diesel generator set is 3 minutes.

[0151] Exemplarily, in the first power supply stage, power is supplied to the data center through a UPS device group to maintain stable operation of the data center load.

[0152] Exemplarily, the second power supply stage supplies power to the data center through a diesel generator set to maintain stable operation of the data center load.

[0153] It is understandable that in the case where the power supply equipment cannot supply power to the data center, in order to meet the power required by the data center load, the power supply equipment is required to supply power to the data center. Since the remaining power of the energy storage device is too low to supply power to the data center, and the diesel generator set has a certain startup time, the UPS device is used to supply power to the data center in the first power supply stage, wherein the duration of the first power supply stage is the startup time of the energy storage device; in the second power supply stage, the diesel generator set is used to supply power to the data center; in this way, during the diesel generator set process, the UPS device (the startup time of the UPS device is shorter) can first supply power to the data center, and then switch after the diesel generator set is started, so as to maintain uninterrupted power supply to the data center.

[0154] In some embodiments, the above method further includes: in the second power supply stage, controlling the diesel generator set to charge the UPS device.

[0155] It is understandable that as a backup power source, the UPS device needs to ensure that it maintains sufficient power so that it can supply power to the data center when the power supply system is abnormal. Therefore, in the second power supply stage, the diesel generator set charges the UPS device while supplying power to the data center.

[0156] It can be understood that the power distribution method provided in the present application, when the power supply system is in an abnormal working state, supplies power to the data center based on at least one of a diesel generator set, an energy storage device, and a UPS device to maintain the operation of the data center, thereby improving the flexibility and stability of the power distribution method.

[0180] a13. Control the UPS equipment to continue to supply power to the data center.
