[0050] A power distribution method provided by the present application will be described in detail below with reference to the accompanying drawings.

[0051] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0052] The terms "first" and "second" and the like in the specification and drawings of this application are used to distinguish different objects, or to distinguish different processing of the same object, rather than to describe a specific order of objects.

[0053] In addition, the terms "including" and "having" and any variations thereof mentioned in the description of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include other steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0054] It should be noted that, in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0055] In order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second", etc. are used to distinguish the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first", "second", etc. are not limiting the quantity and execution order.

[0056] In the description of the present application, unless otherwise specified, “plurality” means two or more.

[0057] With the development of AI technology, the load of data centers has shown the characteristics of high power and high volatility. When building data centers, related technologies calculate power and configure 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 data centers. In addition, due to the high volatility of the load of data centers, the load rate is low in most time periods, resulting in low energy efficiency of the power distribution system and high power efficiency (that is, the ratio of input power to output load power), which is not conducive to energy conservation and emission reduction and control of operating costs.

[0058] In response to the above technical problems, the present 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 status of the power supply system and the output power of the photovoltaic equipment, the power distribution plan of the data center is determined, and the power distribution plan of the data center is executed. The power distribution plan includes photovoltaic equipment to supply power to the data center. The photovoltaic equipment uses solar energy to generate electricity, which reduces dependence on traditional fossil fuel power generation, thereby reducing carbon emissions and increasing control over energy conservation, emission reduction and operating costs. In this way, the data center can effectively reduce the power utilization efficiency and improve the energy efficiency of the power distribution system by adopting the power distribution method of the present application.

[0109] 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.

[0110] 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.

[0111] S202: Determine a power distribution plan for the data center based at least on the load power of the data center, the state of the power supply system, and the output power of the photovoltaic device.

[0112] The power distribution scheme includes providing power to the data center based on at least one or more of a power supply system, energy storage equipment, photovoltaic equipment, and UPS equipment.

[0113] Exemplarily, the status of the power supply system includes a normal status, a power outage status and a dispatching status.

[0114] Exemplarily, when the power supply system is in a normal state, the power supply system can provide stable power to the data center.

[0115] It is understandable that the power supply system under normal conditions has stable voltage and frequency, high power factor, and can provide power continuously.

[0116] Exemplarily, when the power supply system is in a power outage state, the power supply system stops supplying power to the data center.

[0117] Exemplarily, when the power supply system is in a dispatching state, the power of the photovoltaic equipment and the energy storage equipment is sufficient to maintain the normal operation of the data center load, and there is excess power that can be fed back to the power supply system.

[0118] It can be understood that the photovoltaic equipment and the energy storage equipment feed electricity back to the power supply system. After the power supply system receives the electricity from the photovoltaic equipment and the energy storage equipment, it can distribute the electricity to other loads that need electricity, thereby reducing the waste of electricity.

[0119] Exemplarily, the output power of a photovoltaic device is the sum of the electrical energy generated by at least one photovoltaic component per unit time.

[0120] It should be noted that the output power of photovoltaic equipment is determined by the intensity of solar radiation. The greater the intensity of solar radiation, the higher the output power of photovoltaic equipment.

[0121] It can be understood that the intensity of solar radiation is extremely high in clear and cloudless weather with extremely high atmospheric transparency; the intensity of solar radiation is high in clear and cloudless weather or with only a few high clouds; the intensity of solar radiation is moderate in partly clear weather or with occasional clouds; and the intensity of solar radiation is low in cloudy or overcast weather.

[0122] S203: Execute the power distribution plan of the data center.

[0123] Exemplarily, the controller dispatches one or more of a power supply system, an energy storage device, a photovoltaic device, and a UPS device to provide power to the data center based on the configuration plan.

[0124] It can be understood that the power distribution method provided by this application can dynamically adjust the power distribution scheme of the data center based on the load power of the data center, the state of the power supply system and the output power of the photovoltaic equipment, thereby improving the flexibility of the power distribution method. The power distribution system includes photovoltaic equipment, which uses solar energy to generate electricity, reducing dependence on traditional fossil fuel power generation, thereby reducing carbon emissions and increasing control over energy conservation, emission reduction and operating costs. In this way, the power distribution scheme adopted by the data center can effectively reduce the efficiency of power use and improve the energy efficiency of the power distribution system.

[0125] In some embodiments, the above step S202 can be implemented in the following ways:

[0126] Method 1: When the first power distribution state is met, determining the power distribution plan of the data center includes: in the first power supply stage, powering the data center based on the power supply system and UPS equipment; in the second power supply stage, powering the data center based on photovoltaic equipment.

[0127] Among them, the first power distribution state includes: the power supply system is in a normal state, the load power of the data center is greater than or equal to the preset power, and the output power of the photovoltaic equipment is greater than the load power of the data center.

[0128] The duration of the first power supply stage is greater than or equal to the startup duration of the photovoltaic device. Exemplarily, the startup duration of the photovoltaic device is the time required from the photovoltaic device receiving the startup instruction to the photovoltaic device outputting power stably, for example, the startup duration of the photovoltaic device is 80 milliseconds.

[0129] 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.

[0130] It should be noted that with the increase of business data and load equipment in the data center, the load power of the data center will continue to increase. 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, and power supply equipment needs to be added or replaced to smooth out the fluctuations in load power.

[0131] It is understandable that in good weather or above, photovoltaic equipment can maintain the normal operation of the data center, that is, the output power of the photovoltaic equipment is greater than the load power of the data center, and the power supply system can be replaced by photovoltaic equipment. However, since photovoltaic equipment has a certain startup time, this application uses the power supply system and UPS equipment to power the data center in the first power supply stage; wherein, the duration of the first power supply stage is the startup time of the photovoltaic equipment; and the photovoltaic equipment is used to power the data center in the second power supply stage. In this way, during the startup of the photovoltaic equipment, the power supply system and UPS equipment (the startup time of the UPS equipment is shorter) can first power the data center, and then switch after the photovoltaic equipment is started, so as to maintain uninterrupted power supply to the data center.

[0132] In some embodiments, while executing the power distribution scheme in the above-mentioned method 1, the power distribution method provided by the present application further includes the following steps Sa1 to Sa3:

[0133] Sa1. When it is determined that the first preset condition is met, in the second power supply stage, the photovoltaic device is controlled to charge the energy storage device and the UPS device.

[0134] Among them, the first preset condition includes: the remaining power of the energy storage device is less than the preset power upper limit; the difference between the output power of the photovoltaic device and the load power of the data center is greater than or equal to the charging power of the energy storage device and the charging power of the UPS device.

[0135] 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.

[0136] Exemplarily, the preset upper power limit is the maximum value of the remaining power of the energy storage device.

[0137] Exemplarily, the preset upper power limit (SOC1max) is determined by the storage capacity of the energy storage battery in the energy storage device. When the remaining storage capacity of the energy storage batteries is the same, the energy storage battery with a larger storage capacity has more remaining power. For example, the energy storage battery with a larger storage capacity has a higher preset upper power limit.

[0138] Exemplarily, the charging power of the energy storage device is the ratio of the storage capacity of the energy storage battery of the energy storage device to the charging time, wherein the charging time is the time required to fully charge the energy storage battery.

[0139] Exemplarily, the charging power of the UPS device is estimated by the rated power of the UPS. For example, the charging power of the UPS device is a certain ratio (eg, 10% to 15%) of the rated power of the UPS device.

[0140] It is understandable that in clear, cloudless weather with extremely high atmospheric transparency, the solar radiation intensity is extremely high, the photovoltaic equipment has sufficient power to provide the power required for the normal operation of the data center load, and the photovoltaic equipment can also provide sufficient power for the UPS equipment and energy storage equipment, that is, the difference between the output power of the photovoltaic equipment and the load power of the data center is greater than or equal to the charging power of the energy storage equipment and the charging power of the UPS equipment. Based on this, in the second power supply stage, the photovoltaic equipment is controlled to charge the energy storage equipment and the UPS equipment.

[0141] It should be noted that when the remaining power of the energy storage device is greater than or equal to the preset upper limit of power, the internal power of the energy storage device is sufficient and there is no need to charge the energy storage device. When the difference between the output power of the photovoltaic device and the load power of the data center is greater than or equal to the charging power of the energy storage device and the charging power of the UPS device, in the second power supply stage, it is only necessary to control the photovoltaic device to charge the UPS device.

[0142] Sa2. When it is determined that the second preset condition is met, in the second power supply stage, the photovoltaic device is controlled to charge the UPS device.

[0143] The second preset condition includes: the difference between the output power of the photovoltaic device and the load power of the data center is less than or equal to the charging power of the UPS device.

[0144] It is understandable that in clear, cloudless weather or with only a few high clouds, the solar radiation intensity is high, and the power of the photovoltaic device can provide the power required by the data center load, but cannot provide the power required for charging the UPS device, that is, the difference between the output power of the photovoltaic device and the load power of the data center is less than or equal to the charging power of the UPS device. Based on this, in the second power supply stage, the photovoltaic device is preferentially controlled to charge the UPS device.

[0145] It should be noted that since the UPS device is used as a backup power source, it is necessary to ensure that the UPS device maintains sufficient power.

[0146] It should be noted that when the remaining power of the energy storage device is greater than the preset upper limit, the remaining power of the energy storage device is sufficient. In the second power supply stage, when the difference between the output power of the photovoltaic device and the load power of the data center is less than or equal to the charging power of the UPS device, the photovoltaic device and the energy storage device are controlled to charge the UPS device.

[0147] Sa3. When it is determined that the third preset condition is met, in the second power supply stage, the photovoltaic device is controlled to charge the UPS device, and the excess power of the photovoltaic device is used to charge the energy storage device.

[0148] Among them, the third preset condition includes: the remaining power of the energy storage device is less than the preset power upper limit; the difference between the output power of the photovoltaic device and the load power of the data center is greater than the charging power of the UPS device, and less than the sum of the charging power of the energy storage device and the charging power of the UPS device.

[0149] It is understandable that in partially sunny or cloudy weather, the solar radiation intensity is moderate, and the photovoltaic equipment can provide the power required for the normal operation of the data center load and the power required for charging the UPS equipment, but the photovoltaic equipment cannot provide enough power for the energy storage equipment, that is, the difference between the output power of the photovoltaic equipment and the load power of the data center is greater than the charging power of the UPS equipment, and less than the sum of the charging power of the energy storage equipment and the charging power of the UPS equipment. Since the UPS equipment is used as a backup power supply, it is necessary to ensure that the UPS equipment maintains sufficient power. Based on this, in the second power supply stage, the photovoltaic equipment is controlled to charge the UPS equipment. Since the remaining power of the energy storage equipment is less than the preset power limit, the photovoltaic equipment will use the excess power to charge the energy storage equipment.

[0150] It should be noted that when there is too much residual power inside the energy storage device, resulting in the residual power of the energy storage device being greater than the preset upper limit, the power of the photovoltaic device can provide the power required for the normal operation of the data center load and the power required for charging the UPS device, that is, the difference between the output power of the photovoltaic device and the load power of the data center is greater than the charging power of the UPS device, and less than the sum of the charging power of the energy storage device and the charging power of the UPS device. Based on this, in the second power supply stage, the photovoltaic device is controlled to charge the UPS device, and there is no need to charge the energy storage device.

[0151] Method 2: When the second power distribution state is met, determining the power distribution plan of the data center includes supplying power to the data center based on photovoltaic equipment.

[0152] The second power distribution state includes: the power supply system is in a power outage state, and the output power of the photovoltaic equipment is greater than the load power of the data center.

[0153] It is understandable that during peak electricity consumption, when the power supply system is insufficient, the power supply system stops supplying power to the data center. Since there is sufficient sunlight at this time, the photovoltaic equipment can provide the electricity required for the normal operation of the data center load, that is, the output power of the photovoltaic equipment is greater than the load power of the data center. Therefore, the photovoltaic equipment is used to power the data center to maintain the normal operation of the data center load.

[0154] In some embodiments, when it is determined that the remaining power of the energy storage device is less than a preset upper power limit, the photovoltaic device is controlled to charge the energy storage device.

[0155] It is understandable that, due to sufficient sunlight at this time and the intensity of solar radiation is medium or above, the photovoltaic equipment has excess electricity in addition to providing the electricity required for normal operation of the data center. Since the amount of electricity that can be stored in the energy storage device has not reached the upper limit, that is, the remaining electricity of the energy storage device is less than the preset upper limit, the photovoltaic device is controlled to charge the energy storage device.

[0156] It should be noted that although there is sufficient sunlight at this time, the amount of electricity that can be stored in the energy storage device has reached the upper limit, that is, the remaining power of the energy storage device is greater than or equal to the preset upper limit, and the energy storage device does not need to be charged.

[0157] In some embodiments, the power distribution system further includes a diesel generator set.

[0158] Method three: when the third power distribution state is met, determine that the power distribution plan of the data center includes powering the data center based on photovoltaic equipment and diesel generator sets.

[0159] Among them, the third power distribution state includes: the power supply system is in a power outage state, and the output power of the photovoltaic equipment is less than or equal to the load power of the data center.

[0160] It is understandable that during peak electricity consumption, when the power supply system is insufficient, the power supply system stops supplying power to the data center. At this time, the solar radiation intensity is low, and the power provided by the photovoltaic equipment cannot maintain the normal operation of the data center load, that is, the output power of the photovoltaic equipment is less than or equal to the load power of the data center. It is necessary to add new power supply equipment and start the diesel generator set to power the data center together with the photovoltaic equipment and the diesel generator set.

[0161] Method 4: When the fourth power distribution state is met, determining the power distribution plan of the data center includes supplying power to the data center based on photovoltaic equipment.

[0162] Among them, the fourth power distribution state includes: the power supply system is in a scheduling state, and the output power of the photovoltaic equipment is greater than the load power of the data center; the scheduling state is a state where power needs to be fed back to the power supply system.

[0163] It is understandable that when the solar radiation intensity is high, the photovoltaic equipment can maintain the normal operation of the data center load, that is, the output power of the photovoltaic equipment is greater than the load power of the data center, but during peak power consumption periods, the power supply system is insufficient, so it is necessary to feed power back to the power supply system.

[0164] In some embodiments, while executing the power distribution scheme in the fourth method, the following steps Sb1 to Sb2 are also included:

[0165] Sb1. Control the photovoltaic equipment to feed electricity back to the power supply system.

[0166] In some embodiments, the amount of electricity stored in the energy storage device is less than a minimum value, that is, the remaining amount of electricity in the energy storage device is less than a preset lower limit, and the difference between the output power of the photovoltaic device and the load power of the data center is determined to be greater than the charging power of the energy storage device.

[0167] Exemplarily, the preset lower limit of power is the lowest value of the remaining power of the energy storage device.

[0168] Exemplarily, the preset lower limit of power (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 lower limit of power.

[0169] It should be noted that power transmission occurs when there is sufficient electricity in the power distribution system and it can maintain the normal operation of the data center. When the power supply system is short of electricity, it allows the power supply system to provide stable electricity.

[0170] It is understandable that when the solar radiation intensity is high, the electric energy provided by the photovoltaic equipment meets the electric energy required for the normal operation of the data center and the electric energy required for charging the energy storage equipment. That is, the difference between the output power of the photovoltaic equipment and the load power of the data center is greater than the charging power of the energy storage equipment. The photovoltaic equipment can supply power to the data center and charge the energy storage equipment. At the same time, the photovoltaic equipment also has excess electricity to feed power back to the power supply system.

[0171] It should be noted that when the intensity of solar radiation is moderate, the electric energy provided by photovoltaic equipment can maintain the normal operation of the data center, but it cannot provide sufficient electric energy for the energy storage equipment. That is, the difference between the output power of the photovoltaic equipment and the load power of the data center is less than the charging power of the energy storage equipment. Based on this, the photovoltaic equipment gives priority to charging the energy storage equipment and there is no need to feed power back to the power supply system.

[0172] Sb2. When it is determined that the remaining power of the energy storage device is greater than a preset lower limit, the photovoltaic device and the energy storage device are controlled to feed power back to the power supply system.

[0173] It can be understood that when the solar radiation intensity is high, the electric energy provided by the photovoltaic equipment meets the electric energy required for the normal operation of the data center, that is, the output power of the photovoltaic equipment is greater than the load power of the data center, and the amount of electricity stored in the energy storage device is higher than the minimum value, that is, the remaining power of the energy storage device is greater than the preset lower limit of power, and the electric energy inside the energy storage device and the photovoltaic device is sufficient. Based on this, the energy storage device and the photovoltaic device are controlled to feed power back to the power supply system.

[0174] In some embodiments, a power distribution plan for the data center is determined based on the load power of the data center, the status of the power supply system, the output power of the photovoltaic device, and the remaining power of the energy storage device.

[0175] Method 5: When the fifth power distribution state is met, the power distribution plan of the data center is determined to include: in the first power supply stage, the data center is powered by the power supply system and UPS equipment; in the second power supply stage, the data center is powered by photovoltaic equipment and energy storage system.

[0176] The duration of the first power supply stage is greater than or equal to the startup duration of the photovoltaic device or 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.

[0177] Among them, the fifth power distribution state includes: the power supply system is in normal state, the load power of the data center is greater than or equal to the preset power, the output power of the photovoltaic equipment is less than or equal to the load power of the data center, and the remaining power of the energy storage equipment is greater than the preset lower limit.

[0178] It is understandable that in order to meet the power demand of the load of the data center, it is necessary to increase the power supply equipment to supply power to the data center. However, since the photovoltaic equipment and the energy storage equipment have a certain startup time, the present application adopts the power supply system and the UPS equipment 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 equipment or the photovoltaic equipment. The solar radiation intensity is low, and the power provided by the photovoltaic equipment cannot maintain the normal operation of the load of the data center. It is necessary to increase the power supply equipment. Since the power stored in the energy storage equipment is greater than the minimum value, that is, the remaining power of the energy storage equipment is greater than the preset power lower limit, the photovoltaic equipment and the energy storage equipment are used to supply power to the data center in the second power supply stage; in this way, during the startup of the photovoltaic equipment and the energy storage equipment, the UPS equipment (the startup time of the UPS equipment is shorter) can first supply power to the data center, and then switch after the photovoltaic equipment and the energy storage equipment are started, so as to maintain the uninterrupted power supply of the data center.

[0179] In some embodiments, in the second power supply stage, the energy storage device is controlled to charge the UPS device.

[0180] It is understandable that as a backup power source, the UPS device needs to ensure that it maintains sufficient power so that it can power the data center when the power supply system is abnormal. Therefore, in the second power supply stage, the energy storage device charges the UPS device while supplying power to the data center.

[0181] Method six: when the sixth power distribution state is met, determining the power distribution plan of the data center includes: in the first power supply stage, powering the data center based on the power supply system and UPS equipment; in the second power supply stage, powering the data center based on photovoltaic equipment and the power supply system.

[0182] The duration of the first power supply stage is greater than or equal to the startup duration of the photovoltaic device.

[0183] Among them, the sixth power distribution state includes: the power supply system is in normal state, the load power of the data center is greater than or equal to the preset power, the remaining power of the energy storage device is less than the preset power lower limit, and the output power of the photovoltaic device is less than or equal to the load power of the data center.

[0184] 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 photovoltaic equipment has a certain startup time, the present application uses a power supply system and UPS equipment to power the data center in the first power supply stage; wherein, the duration of the first power supply stage is the startup time of the photovoltaic equipment; in the second power supply stage, the power supply system and photovoltaic equipment are used to power the data center; in this way, during the startup of the photovoltaic equipment, the UPS equipment (the startup time of the UPS equipment is shorter) can first power the data center, and then switch after the photovoltaic equipment is started, so as to maintain uninterrupted power supply to the data center.

[0185] In some embodiments, in the second power supply stage, the power supply system is controlled to charge the UPS device.

[0186] 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.

[0187] Method seven: When the seventh power distribution state is met, determine the power distribution plan of the data center, including powering the data center based on diesel generator sets, photovoltaic equipment and energy storage equipment.

[0188] Among them, the seventh power distribution state includes: the power supply system is in a power outage state, the output power of the photovoltaic equipment is less than or equal to the load power of the data center, and the remaining power of the energy storage equipment is greater than the preset lower limit.

[0189] It is understandable that during peak electricity consumption, when the power supply system is insufficient, the power supply system stops supplying power to the data center. At this time, the solar radiation intensity is weak, and the photovoltaic equipment cannot provide the electricity required for the normal operation of the data center load, that is, the output power of the photovoltaic equipment is less than or equal to the load power of the data center. It is necessary to increase the power supply equipment and start the diesel generator set. At this time, the amount of electricity stored in the energy storage device is greater than the minimum value, that is, the remaining power of the energy storage device is greater than the preset lower limit. Therefore, the data center is powered by the diesel generator set, photovoltaic equipment and energy storage equipment to maintain the normal operation of the data center.

[0190] The following three specific embodiments respectively introduce the states of the three power supply systems provided in the embodiments of the present application.
