[0105] When the status information of all Class I power supply devices indicates that all Class I power supply devices are in an abnormal state, the power supply stability of at least one target Class II power supply device in a normal state and the available power of each target Class II power supply device within a preset unit time period are determined based on the status information of all Class II power supply devices. Then, based on one or more of the following: the power stability requirement of each load device, the power consumption of each load device within a preset unit time period, the power supply stability of each target Class II power supply device, and the available power of each target Class II power supply device within a preset unit time period, the power supply device matching each load device is determined among all target Class II power supply devices, and this device is used as the target power supply device for data center adaptation.

[0106] When the status information of all first power supply devices indicates that there is at least one target first power supply device in a normal state, based on the status information of all target first power supply devices, determine the first total available power of all target first power supply devices in a preset unit time period, the available power of each target first power supply device in a preset unit time period, and the power supply stability of each target first power supply device, and determine whether the first total available power is greater than or equal to the total power consumption.

[0107] When it is determined that the first available total power is greater than or equal to the total power consumption, the power supply device matching each load device is determined from all target first-class power supply devices based on one or more of the following: power consumption of each load device in a preset unit time period, power stability requirements of each load device, available power of each target first-class power supply device in a preset unit time period, and power supply stability of each target first-class power supply device. This device is then used as the target power supply device for data center adaptation.

[0108] When it is determined that the first available total power is less than the total power consumption, the power supply stability of at least one target second-class power supply device in normal state and the available power of each target second-class power supply device within a preset unit time period are determined based on the status information of all second-class power supply devices. Then, based on one or more of the following: the power consumption stability requirement of each load device, the power consumption of each load device within a preset unit time period, the available power of each target first-class power supply device within a preset unit time period, the power supply stability of each target first-class power supply device, the available power of each target second-class power supply device within a preset unit time period, and the power supply stability of each target second-class power supply device, the power supply device matching each load device is determined from all target first-class power supply devices and all target second-class power supply devices, and this device is used as the target power supply device for data center adaptation.

[0109] In this optional implementation, the power supply devices that match any two load devices can be the same target power supply device or different target power supply devices, and each load device can correspond to one or more target power supply devices.

[0110] As can be seen, implementing this optional implementation method can determine the matching power supply equipment for each load device based on the power consumption information of each load device and the power supply information of each power supply device, thereby improving the accuracy, reliability and adaptability of determining the target power supply equipment. Furthermore, the second type of power supply equipment, namely the energy storage power supply equipment, is only activated to supply power when the first available power of the first type of power supply equipment is less than the total power consumption. This can reduce the energy consumption of the energy storage of the second type of power supply equipment while ensuring sufficient power supply, thereby improving the emergency response capability of the data center for abnormal power supply conditions.

[0111] 103. Determine the power supply parameters corresponding to each target power supply device based on the load status.

[0112] 104. Based on the power supply parameters corresponding to each target power supply device, control all target power supply devices to perform matching power supply operations to all load devices in the data center.

[0113] As can be seen, implementing the embodiments of the present invention can determine the appropriate power supply equipment and power supply parameters based on the real-time load status of the data center, reducing the occurrence of power supply redundancy or insufficient power supply due to mismatch between the power supply equipment or power supply parameters and the power demand of the load equipment, improving the matching degree between the actual power supply and actual power demand of the data center, thereby improving the accuracy, reliability and flexibility of data center power supply, and further reducing the energy loss of the data center and improving the energy utilization rate of the data center.

[0114] In an optional embodiment, before determining the power supply parameters corresponding to each target power supply device based on the load status, the method may further include:

[0115] Based on the power supply equipment matched to each load device, determine the power supply target of each target power supply device among all load devices;

[0116] Determining the power supply parameters for each target power supply device based on the load status can include:

[0117] The power supply parameters for each target power supply device are determined based on the load status and the power supply object of each target power supply device.

[0118] It is evident that implementing this optional embodiment can improve the adaptability and accuracy of the determined power supply parameters.

[0119] In this optional embodiment, as an optional implementation method, determining the power supply parameters corresponding to each target power supply device based on the load status and the power supply object of each target power supply device may include:

[0120] Determine the load information for each load device based on its load status;

[0121] For each target power supply device, determine whether there is a target load device among the power supply objects of the target power supply device, wherein the target load device includes load devices with a number of matching power supply devices greater than 1;

[0122] For each target power supply device, when the target power supply device includes a target load device, the appropriate power supply power corresponding to the target power supply device is determined based on the load information of each load device in the target power supply device and the power supply coefficient of all target power supply devices that match each target load device in the target power supply device, and is used as the power supply parameter of the target power supply device.

[0123] For each target power supply device, when the target load device is not included in the power supply objects of the target power supply device, the appropriate power supply power corresponding to the target power supply device is determined based on the load information of each load device in the power supply objects of the target power supply device and the power supply coefficient of the target power supply device, and is used as the power supply parameter of the target power supply device.

[0124] Specifically, for each target power supply device, when the target power supply device is a first-class power supply device, the power supply coefficient of the target power supply device includes the maximum power supply power of the target power supply device; when the target power supply device is a second-class power supply device, the power supply coefficient of the target power supply device includes the maximum power supply power of the target power supply device and the remaining power of the target power supply device; and the maximum power supply power of each target power supply device includes the maximum power supply power of the target power supply device and the minimum power supply power of the target power supply device.

[0125] It is evident that implementing this optional implementation method can determine the power supply parameters of each target power supply device based on the relevant information of the load device and the power supply device, as well as the correlation between the load device and the power supply device. This improves the matching degree between the determined power supply parameters and the power demand of the load device, thereby improving the accuracy and reliability of the power supply parameter determination and reducing excessive losses of the power supply device caused by unreasonable power supply parameters.

[0126] In this optional embodiment, as another optional implementation, controlling all target power supply devices to perform matching power supply operations on all load devices in the data center based on the power supply parameters corresponding to each target power supply device may include:

[0127] For each target power supply device, when there is a first power supply object whose load attributes do not match the direct power supply attributes of the target power supply device, a conversion operation is performed on the first original current output by the target power supply device to the first power supply object based on the first power supply parameters corresponding to the first power supply object of the target power supply device in the power supply parameters corresponding to the target power supply device, to obtain the first adapted current corresponding to the first power supply object of the target power supply device; and the first adapted current corresponding to the first power supply object of the target power supply device is input to the tree-structured power distribution system of the data center, so that the tree-structured power distribution system distributes the first adapted current corresponding to the first power supply object of the target power supply device to the first power supply object of the target power supply device;

[0128] For each target power supply device, when there is a second power supply object whose load attributes match the direct power supply attributes of the target power supply device, the target power supply device is controlled to input the second adaptive current corresponding to the second power supply object of the target power supply device into the tree-structured power distribution system of the data center according to the second power supply parameters of the target power supply device. This allows the tree-structured power distribution system to distribute the second adaptive current corresponding to the second power supply object of the target power supply device to the second power supply object of the target power supply device.

[0129] Among them, the direct supply attribute of each Class I power supply device includes AC direct supply attribute, the direct supply attribute of each Class II power supply device includes DC direct supply attribute, and the load attribute of each load device includes AC load attribute or DC load attribute.

[0130] In this optional implementation, preferably, the tree-like power distribution system may include an intelligent small busbar power distribution system, thereby reducing the installation space of the tree-like power distribution system, improving the convenience and flexibility of data center maintenance and expansion, reducing the operation and maintenance costs of the data center, and reducing power line transmission losses.

[0131] It is evident that implementing this optional implementation method can convert the current supplied by the power supply equipment, realize the mutual conversion between DC and AC, improve the matching degree between the supplied current type and the power demand of the load equipment, and thus improve the accuracy and reliability of power supply.

[0132] In this optional implementation, optionally, for each target power supply device, when the target power supply device is a first type of power supply device, according to the first power supply parameters corresponding to the first power supply object of the target power supply device in the power supply parameters corresponding to the target power supply device, a conversion operation is performed on the first original current output by the target power supply device for the first power supply object of the target power supply device to obtain the first adapted current corresponding to the first power supply object of the target power supply device, which may include:

[0133] Based on the power supply parameters corresponding to the first power supply object of the target power supply equipment, determine the three-phase rectifier module to be enabled, the voltage regulation module to be enabled, the three-phase rectifier parameters adapted to the three-phase rectifier module, and the voltage regulation parameters adapted to the voltage regulation module in the current conversion equipment corresponding to the target power supply equipment.

[0134] Based on the first power supply parameters corresponding to the first power supply object of the target power supply equipment, the target power supply equipment is controlled to input a matching three-phase AC current to the three-phase rectifier module;

[0135] Based on the three-phase rectification parameters adapted to the three-phase rectifier module, the three-phase rectifier module is controlled to rectify the three-phase AC current to obtain rectified DC current.

[0136] Based on the voltage regulation parameters adapted to the voltage regulation module, the voltage regulation module is controlled to regulate the rectified DC current, thereby obtaining the first adapted current corresponding to the first power supply object of the target power supply equipment.

[0137] like Figure 3 As shown, the current conversion device of the first type of power supply equipment can be a medium-voltage AC (Alternating Current) to DC (Direct Current) communication device. The three-phase rectifier module of the medium-voltage AC to DC communication device includes a three-phase uncontrolled rectifier module, and the voltage regulation module of the medium-voltage AC to DC communication device includes a Buck voltage regulation module (step-down module).

[0138] It is evident that implementing this optional implementation method can also gradually convert the AC power provided by the first power supply equipment into DC power based on the three-phase rectifier module and voltage regulation module, realizing the integration, modularization and simplification of current conversion, thereby improving the power density of current conversion, reducing energy loss caused by current conversion, and improving the efficiency, accuracy and reliability of current conversion. In addition, it can also help reduce the energy consumption of the second type of power supply equipment while ensuring sufficient power supply, so as to improve the emergency response capability of the data center for abnormal power supply conditions.

[0139] In another alternative embodiment, before determining the power supply parameters corresponding to each target power supply device based on the load status, the method may further include:

[0140] When the second type of power supply equipment is not included among all target power supply equipment and when the first total available power is greater than the total power consumption, determine whether there is at least one power supply equipment that is not fully charged among all the second type of power supply equipment based on the status information of each second type of power supply equipment.

[0141] When the judgment result is yes, the redundant power corresponding to the first available total power is determined. The redundant power is the power difference between the first available total power and the total power consumption.

[0142] Based on the redundant power, at least one device to be charged is identified from all devices that are not fully charged, and each device to be charged is identified as one of the load devices in the data center;

[0143] Reacquire the current load status of the data center and trigger the above operation to determine the power supply parameters corresponding to the target power supply equipment based on the load status.

[0144] As can be seen, implementing this optional embodiment can charge the second type of power supply equipment that needs to be charged when the power supply of the first type of power supply equipment meets the power demand of the load equipment and there is redundancy. This enables intelligent charging of the second type of power supply equipment, which is beneficial to timely replenish the energy storage of the second type of power supply equipment and improve the emergency response capability of the data center in response to abnormal power supply conditions.

[0145] Implementation 2

[0146] Please see Figure 2 , Figure 2 This is a flowchart illustrating a power supply and distribution method for a data center according to an embodiment of the present invention. Wherein, Figure 2 The described power supply and distribution method for data centers can be applied to the power supply and distribution control system of data centers, and the embodiments of the present invention are not limited thereto. Figure 2 As shown, the power supply and distribution method of this data center may include the following operations:

[0147] 201. Obtain the current load status of the data center and the status information of at least one power supply device in the data center. All power supply devices include at least one Class I power supply device and at least one Class II power supply device. Each Class I power supply device includes a mains power supply device or a power generation device, and each Class II power supply device includes a battery storage device.

[0148] 202. Determine at least one target power supply device to be adapted to the data center based on the load status and the status information of all power supply devices.

[0149] 203. When all target power supply equipment includes at least one Class II power supply equipment, determine whether the total available power of all target power supply equipment within a preset unit time period is less than the total power consumption.

[0150] 204. When it is determined that the total available power is less than the total power consumption, determine the equipment type of each load device.

[0151] 205. Determine the priority level of each load device based on its device type.

[0152] Each load device's equipment type includes a first equipment type for meeting the living needs of the data center and / or a second equipment type for meeting the production needs of the data center. For example, the air conditioning equipment in a data center can be used to heat up or cool down the work area of ​​the data center staff, or it can be used to cool down the work area (computer room) of the computing equipment in the data center. Therefore, the equipment type of the air conditioning equipment can include the first equipment type and / or the second equipment type, while the equipment type of the computing equipment only includes the second equipment type.

[0153] 206. Perform matching pre-energy-saving operations on all load devices according to the priority level of each load device.

[0154] As an optional implementation, performing matching pre-energy-saving operations on all load devices based on the priority level of each load device may include:

[0155] Determine the set of devices consisting of all load devices;

[0156] The system identifies at least one load device with the lowest priority in the device set as the energy-saving device in the data center. Based on the working status of each energy-saving device, it performs a matching pre-energy-saving operation on each energy-saving device. After the pre-energy-saving operation is performed, the power consumption of the data center within a preset unit time period is updated to the total power consumption, and it is determined whether the total available power is less than the total power consumption.

[0157] When it is determined that the total available power is less than the total power consumption, all devices to be saved are removed from the device set, and the above-mentioned process of identifying at least one load device with the lowest priority in the device set as the data center's energy-saving device is re-executed. Based on the working status of each energy-saving device, a matching pre-energy-saving operation is performed on each energy-saving device, and the power consumption of the data center within a preset unit time period after the pre-energy-saving operation is performed is updated to the total power consumption. The operation of determining whether the total available power is less than the target power consumption is also performed until the total available power is greater than or equal to the total power consumption.

[0158] For example, when one of the air conditioning devices in a data center is a device to be saved, if the air conditioning device is in cooling mode, the operating temperature of the air conditioning device can be increased and the air output power of the air conditioning device can be reduced, thereby achieving the pre-energy saving operation matched to the air conditioning device; when one of the computing devices in a data center is a device to be saved, unnecessary computing processes or computing processes with low importance in the computing device can be suspended or terminated, thereby achieving the pre-energy saving operation matched to the computing device.

[0159] As can be seen, implementing this optional implementation method can perform matching pre-energy-saving operations on the load devices in a hierarchical manner, thereby gradually reducing the total power consumption of the data center while ensuring that the power demand of the more important load devices is met, reducing unnecessary energy loss in the data center, and improving the energy efficiency of the data center.

[0160] 207. Retrieve the current load status of the data center.

[0161] 208. Determine the power supply parameters corresponding to each target power supply device based on the load status.

[0162] 209. Based on the power supply parameters corresponding to each target power supply device, control all target power supply devices to perform matching power supply operations to all load devices in the data center.

[0163] In this embodiment of the invention, for other descriptions of steps 201, 202, 207 and 208, please refer to the detailed description of steps 101-104 in Embodiment 1. These descriptions will not be repeated in this embodiment of the invention.

[0164] As can be seen, implementing the embodiments of the present invention can determine the appropriate power supply equipment and power supply parameters based on the real-time load status of the data center, reducing the occurrence of power supply redundancy or insufficient power supply due to mismatch between the power supply equipment or power supply parameters and the power demand of the load equipment, improving the matching degree between the actual power supply and actual power demand of the data center, thereby improving the accuracy, reliability and flexibility of data center power supply, and further reducing the energy consumption of the data center and improving the energy utilization rate of the data center. In addition, it can also perform matching pre-energy saving operations on the load equipment according to the equipment type of the load equipment when the power supply is insufficient, reducing unnecessary energy consumption of the data center and improving the effective utilization of energy in the data center.

[0165] In an optional embodiment, before determining the priority level of each load device based on its device type, the method may further include:

[0166] Determine if there are any dynamic load devices with a dynamic priority attribute among all load devices. The priority attribute of each load device can be either a fixed attribute or a dynamic attribute.

[0167] When dynamic load devices exist, the priority level change of each dynamic load device is determined based on the corresponding real-time parameters, and the above-mentioned operation of determining the priority level of each load device based on the device type of each load device is triggered.

[0168] When no dynamic load device exists, the above-mentioned operation of determining the priority level of each load device based on the device type of each load device is triggered.

[0169] When dynamic load devices exist, determining the priority level of each load device based on its device type can include:

[0170] The priority level of each load device is determined based on its device type and the corresponding real-time parameters according to the priority changes of each dynamic load device.

[0171] The priority of dynamic load devices can be changed based on one or more of the following: time, number of people, business needs, etc. For example, air conditioning equipment has a higher priority in summer than in winter, and lighting equipment has a lower priority during the day than at night. It can be seen that both air conditioning equipment and lighting equipment are dynamic load devices, with season as the basis for the priority change of air conditioning equipment and time as the basis for the priority change of lighting equipment.

[0172] As can be seen, implementing this optional embodiment can determine the priority level of the load device based on the corresponding real-time parameters in combination with the priority level changes of the dynamic load device, thereby improving the flexibility and diversity of priority level determination.

[0173] Example 3

[0174] Please see Figure 4 , Figure 4 This is a schematic diagram of the power supply and distribution device for a data center disclosed in an embodiment of the present invention. Figure 4 The described power supply and distribution equipment for data centers can be applied to the power supply and distribution control system of data centers, and the embodiments of the present invention are not limited thereto. Figure 4 As shown, the power supply and distribution equipment of the data center may include:

[0175] The acquisition module 301 is used to acquire the current load status of the data center and the status information of at least one power supply device in the data center;

[0176] The determination module 302 is used to determine at least one target power supply device adapted to the data center based on the load status and the status information of all power supply devices; and to determine the power supply parameters corresponding to each target power supply device based on the load status.

[0177] The power supply control module 303 is used to control all target power supply devices to perform matching power supply operations on all load devices in the data center based on the power supply parameters corresponding to each target power supply device.

[0178] It is evident that implementation Figure 4 The described device can determine the appropriate power supply equipment and power supply parameters based on the real-time load status of the data center, reducing the occurrence of power supply redundancy or insufficient power supply caused by mismatch between the power supply equipment or power supply parameters and the power demand of the load equipment. This improves the matching degree between the actual power supply and actual power demand of the data center, thereby improving the accuracy, reliability and flexibility of the data center power supply, and ultimately reducing the energy loss and improving the energy utilization rate of the data center.

[0179] In an optional embodiment, such as Figure 4 As shown, all power supply equipment includes at least one Class I power supply equipment and at least one Class II power supply equipment. Each Class I power supply equipment includes a mains power supply device or a power generation device, and each Class II power supply equipment includes an energy storage power supply device.

[0180] The specific method by which module 302 determines at least one target power supply device for data center adaptation based on load status and status information of all power supply devices may include:

[0181] Based on the load status, determine the power stability requirements of each load device in the data center, the power consumption of each load device within a preset unit time period, and the total power consumption of the data center within the preset unit time period.

[0182] When the status information of all Class I power supply devices indicates that all Class I power supply devices are in an abnormal state, the power supply stability of at least one target Class II power supply device in a normal state and the available power of each target Class II power supply device within a preset unit time period are determined based on the status information of all Class II power supply devices. Then, based on one or more of the following: the power stability requirement of each load device, the power consumption of each load device within a preset unit time period, the power supply stability of each target Class II power supply device, and the available power of each target Class II power supply device within a preset unit time period, the power supply device matching each load device is determined among all target Class II power supply devices, and this device is used as the target power supply device for data center adaptation.

[0183] When the status information of all first power supply devices indicates that there is at least one target first power supply device in a normal state, based on the status information of all target first power supply devices, determine the first total available power of all target first power supply devices in a preset unit time period, the available power of each target first power supply device in a preset unit time period, and the power supply stability of each target first power supply device, and determine whether the first total available power is greater than or equal to the total power consumption.

[0184] When it is determined that the first available total power is greater than or equal to the total power consumption, the power supply device matching each load device is determined from all target first-class power supply devices based on one or more of the following: power consumption of each load device in a preset unit time period, power stability requirements of each load device, available power of each target first-class power supply device in a preset unit time period, and power supply stability of each target first-class power supply device. This device is then used as the target power supply device for data center adaptation.

[0185] When it is determined that the first available total power is less than the total power consumption, the power supply stability of at least one target second-class power supply device in normal state and the available power of each target second-class power supply device within a preset unit time period are determined based on the status information of all second-class power supply devices. Then, based on one or more of the following: the power consumption stability requirement of each load device, the power consumption of each load device within a preset unit time period, the available power of each target first-class power supply device within a preset unit time period, the power supply stability of each target first-class power supply device, the available power of each target second-class power supply device within a preset unit time period, and the power supply stability of each target second-class power supply device, the power supply device matching each load device is determined from all target first-class power supply devices and all target second-class power supply devices, and this device is used as the target power supply device for data center adaptation.

[0186] It is evident that implementation Figure 4 The described device can also determine the matching power supply equipment for each load device based on the power stability requirements and power consumption of each load device, as well as the operating status, power supply stability, and available power of each power supply device. This improves the accuracy, reliability, and adaptability of determining the target power supply equipment. Furthermore, the second type of power supply equipment, namely the energy storage power supply equipment, is only activated when the first available power of the first type of power supply equipment is less than the total power consumption. This reduces the energy consumption of the second type of power supply equipment while ensuring sufficient power supply, thereby improving the data center's emergency response capability to abnormal power supply conditions.

[0187] In another alternative embodiment, such as Figure 4As shown, the determining module 302 is also used to determine the power supply object of each target power supply device among all load devices, based on the power supply device that matches each load device, before determining the power supply parameters corresponding to each target power supply device according to the load status.

[0188] The specific method by which module 302 determines the power supply parameters corresponding to each target power supply device based on the load status may include:

[0189] Determine the power supply parameters for each target power supply device based on the load status and the power supply object of each target power supply device.

[0190] The power supply control module 303 controls all target power supply devices to perform matching power supply operations on all load devices in the data center based on the power supply parameters corresponding to each target power supply device. Specific methods may include:

[0191] For each target power supply device, when there is a first power supply object whose load attributes do not match the direct power supply attributes of the target power supply device, a conversion operation is performed on the first original current output by the target power supply device to the first power supply object based on the first power supply parameters corresponding to the first power supply object of the target power supply device in the power supply parameters corresponding to the target power supply device, to obtain the first adapted current corresponding to the first power supply object of the target power supply device; and the first adapted current corresponding to the first power supply object of the target power supply device is input to the tree-structured power distribution system of the data center, so that the tree-structured power distribution system distributes the first adapted current corresponding to the first power supply object of the target power supply device to the first power supply object of the target power supply device;

[0192] For each target power supply device, when there is a second power supply object whose load attributes match the direct power supply attributes of the target power supply device, the target power supply device is controlled to input the second adaptive current corresponding to the second power supply object of the target power supply device into the tree-structured power distribution system of the data center according to the second power supply parameters of the target power supply device. This allows the tree-structured power distribution system to distribute the second adaptive current corresponding to the second power supply object of the target power supply device to the second power supply object of the target power supply device.

[0193] Among them, the direct supply attribute of each Class I power supply device includes AC direct supply attribute, the direct supply attribute of each Class II power supply device includes DC direct supply attribute, and the load attribute of each load device includes AC load attribute or DC load attribute.

[0194] It is evident that implementation Figure 4The described device can also convert the current supplied by the power supply equipment, realize the mutual conversion between DC and AC, improve the matching degree between the type of current supplied and the power demand of the load equipment, and thus improve the accuracy and reliability of power supply.

[0195] In yet another alternative embodiment, such as Figure 4 As shown, for each target power supply device, when the target power supply device is a first type of power supply device, the power supply control module 303 performs a conversion operation on the first original current output by the target power supply device for the first power supply object of the target power supply device according to the first power supply parameters of the first power supply object of the target power supply device in the power supply parameters corresponding to the target power supply device. The specific method to obtain the first adapted current corresponding to the first power supply object of the target power supply device may include:

[0196] Based on the power supply parameters corresponding to the first power supply object of the target power supply equipment, determine the three-phase rectifier module to be enabled, the voltage regulation module to be enabled, the three-phase rectifier parameters adapted to the three-phase rectifier module, and the voltage regulation parameters adapted to the voltage regulation module in the current conversion equipment corresponding to the target power supply equipment.

[0197] Based on the first power supply parameters corresponding to the first power supply object of the target power supply equipment, the target power supply equipment is controlled to input a matching three-phase AC current to the three-phase rectifier module;

[0198] Based on the three-phase rectification parameters adapted to the three-phase rectifier module, the three-phase rectifier module is controlled to rectify the three-phase AC current to obtain rectified DC current.

[0199] Based on the voltage regulation parameters adapted to the voltage regulation module, the voltage regulation module is controlled to regulate the rectified DC current, thereby obtaining the first adapted current corresponding to the first power supply object of the target power supply equipment.

[0200] It is evident that implementation Figure 4 The described device can also gradually convert the AC power provided by the first power supply equipment into DC power based on the three-phase rectifier module and the voltage regulation module, realizing the integration, modularization and simplification of current conversion, thereby improving the power density of current conversion, reducing energy loss caused by current conversion, and improving the efficiency, accuracy and reliability of current conversion. In addition, it can also help reduce the energy consumption of the second type of power supply equipment while ensuring sufficient power supply, so as to improve the emergency response capability of the data center for abnormal power supply conditions.

[0201] In yet another alternative embodiment, such as Figure 5 As shown, the device may further include:

[0202] The first judgment module 304 is used to determine, before the determination module 302 determines the power supply parameters corresponding to each target power supply device according to the load status, whether there is at least one power supply device that is not fully charged among all the second type of power supply devices when the second type of power supply devices are not included among all the target power supply devices and when the first available total power is greater than the total power consumption, based on the status information of each second type of power supply device.

[0203] The determining module 302 is further configured to, when the first determining module 304 determines that there is at least one device that is not fully powered, determine the redundant power corresponding to the first available total power, wherein the redundant power is the power difference between the first available total power and the total power consumption; and, based on the redundant power, determine at least one device to be charged from all devices that are not fully powered, and determine each device to be charged as one of the load devices in the data center.

[0204] The acquisition module 301 is also used to reacquire the current load status of the data center and trigger the determination module 302 to perform the above-mentioned operation of determining the power supply parameters corresponding to the target power supply equipment based on the load status.

This realizes the intelligent charging of the second type of power supply equipment, which is conducive to timely replenishment of the power storage of the second type of power supply equipment and improves the emergency response capability of the data center in response to abnormal power supply conditions.

[0206] In yet another alternative embodiment, such as Figure 5 As shown, the device may further include:

[0208] The determining module 302 is further configured to determine the device type of each load device when the second determining module 305 determines that the total available power is less than the total power consumption, and determine the priority level of each load device according to the device type of each load device, wherein the device type of each load device includes a first device type for meeting the living needs of the data center and / or a second device type for meeting the production needs of the data center;

[0214] The system identifies at least one load device with the lowest priority in the device set as the energy-saving device in the data center. Based on the working status of each energy-saving device, it performs a matching pre-energy-saving operation on each energy-saving device. After the pre-energy-saving operation is performed, the power consumption of the data center within a preset unit time period is updated to the total power consumption, and it is determined whether the total available power is less than the total power consumption.

[0215] When it is determined that the total available power is less than the total power consumption, all devices to be saved are removed from the device set, and the above-mentioned process of identifying at least one load device with the lowest priority in the device set as the data center's energy-saving device is re-executed. Based on the working status of each energy-saving device, a matching pre-energy-saving operation is performed on each energy-saving device, and the power consumption of the data center within a preset unit time period after the pre-energy-saving operation is performed is updated to the total power consumption. The operation of determining whether the total available power is less than the target power consumption is also performed until the total available power is greater than or equal to the total power consumption.

[0216] It is evident that implementation Figure 5 The described device can also perform matching pre-energy-saving operations on load devices in a hierarchical manner, thereby gradually reducing the total power consumption of the data center while ensuring that the power demand of the more critical load devices is met, reducing unnecessary energy loss in the data center, and improving the energy efficiency of the data center.
