When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0064] To clearly understand the technical solution of this application, the solutions of the prior art will be described in detail first.

[0065] The ICT power supply system consists of high / low voltage power distribution, transformers, power conversion equipment (UPS system and high voltage DC system, etc.) to provide power supply for ICT equipment (including communication equipment and servers); in order to ensure the reliable operation of ICT equipment, the computer room air conditioning is also required for cooling.

[0066] In practical engineering applications of ICT data centers, there are often situations where ICT equipment is added or removed. When ICT equipment is added or removed, it will affect the conversion losses of transformers and power conversion equipment, as well as the power consumption of air conditioning.

[0067] Therefore, when adding or removing ICT devices, the existing technology lacks an assessment of the power supply capacity of the ICT power supply system.

[0068] To address the aforementioned issues, the inventors discovered in their research that the power of ICT devices in the estimated state can be determined by the power of the ICT devices to be added or reduced. Based on the existing ICT device power and corresponding PUE data, the PUE in the estimated state can be determined. Based on the ICT device power and PUE in the estimated state, the air conditioner power in the estimated state can be obtained. Based on the ICT device power in the estimated state and the load rate and efficiency curves of the power conversion equipment, the input power of the power conversion equipment can be obtained. Based on the input power of the power conversion equipment, the power of the air conditioner, and the load rate and efficiency curves of the transformer, the input power of the transformer can be obtained. Thus, the power consumption of the entire power supply system can be obtained, facilitating energy consumption simulation.

Specifically, the first ICT device configuration status, the second ICT device configuration status, and the third ICT device configuration status have different ICT device power. In addition, in order to facilitate the estimation of the power of the third cooling device in the third ICT device configuration status, the first ICT device configuration status and the second ICT device configuration status are preset as estimated device configuration statuses, and the third ICT device configuration status is the device configuration status to be estimated.

[0076] The estimated equipment configuration status can refer to the current configuration status of ICT equipment in the data center, which can be obtained directly by measuring the power of ICT equipment and cooling equipment using power measurement tools.

In addition, the estimated equipment configuration status can also refer to the full-load status when the data center was designed, in which the full-load power and full-load PUE of ICT equipment can be known. Specifically, the full-load power data of ICT equipment under full-load status can be obtained from the data center design, and the full-load PUE can be obtained from the actual measurement during the data center's completion and acceptance, or from the design calculation report.

[0077] PUE (Power Usage Effectiveness) can refer to the ratio of all energy consumed by a data center to the energy consumed by the IT load. In this embodiment, PUE can refer to the ratio of the sum of the power of ICT equipment and the power of cooling equipment to the power of the ICT equipment.

[0082] Based on the power of the first ICT equipment and the power of the first cooling equipment, determine the first PUE of the data center under the configuration state of the first ICT equipment;

[0083] Based on the power of the second ICT equipment and the power of the second cooling equipment, determine the second PUE of the computer room under the configuration state of the second ICT equipment.

[0084] Among them, refrigeration equipment can refer to air conditioners, which are used to cool down the computer room.

[0085] A method for determining the first PUE of a data center under the first ICT equipment configuration state may include: determining the first PUE based on the ratio of the sum of the power of the first ICT equipment and the power of the first cooling equipment to the power of the first ICT equipment.

[0086] A method for determining the second PUE of a data center under the second ICT equipment configuration state may include: determining the second PUE based on the ratio of the sum of the power of the second ICT equipment and the power of the second cooling equipment to the power of the second ICT equipment.

[0087] In this embodiment of the application, by determining the first PUE, the second PUE, the power of the first ICT device, the power of the second ICT device, and the power of the third ICT device, a data basis is provided for calculating the power of the third cooling device.

[0088] S202. Based on the power of the first ICT device, the first PUE, the power of the second ICT device, the second PUE, and the power of the third ICT device, determine the power of the third ICT device in the third ICT device configuration state, wherein the power of the first ICT device is the power of the ICT device in the first ICT device configuration state, and the power of the second ICT device is the power of the ICT device in the second ICT device configuration state.

[0089] In this embodiment of the application, determining the power of the third refrigeration device in the third ICT device configuration state based on the power of the first ICT device, the first PUE, the power of the second ICT device, the second PUE, and the power of the third ICT device includes:

[0090] Determine the number of energy consumption assessments required for refrigeration equipment;

[0091] If the number of energy consumption assessments for the cooling equipment is less than or equal to the preset target number, then obtain the power of the second ICT equipment and the second PUE when the second ICT equipment is configured as a full-load device.

[0092] Based on the power of the first ICT device, the first PUE, the power of the second ICT device, the second PUE, and the power of the third ICT device, determine the third PUE of the data center when the third ICT device is configured.

[0093] The power of the third cooling device is determined based on the third PUE and the power of the third ICT device in the configuration state of the third ICT device.

[0094] In this embodiment of the application, after determining the number of energy consumption assessments for the refrigeration equipment, the method further includes:

[0095] If the number of energy consumption assessments for the cooling equipment exceeds the target number, then the second ICT equipment configuration status is obtained as the estimated power and second PUE of the second ICT equipment.

[0096] Based on the power of the first ICT device, the first PUE, the power of the second ICT device, the second PUE, and the power of the third ICT device, determine the third PUE of the data center when the third ICT device is configured.

[0097] The power of the third cooling device is determined based on the third PUE and the power of the third ICT device in the configuration state of the third ICT device.

[0098] To differentiate the ICT equipment configuration states required for calculating the cooling equipment's power, a target number of iterations is preset. By determining the relationship between the number of energy consumption assessments of the cooling equipment and the target number of iterations, the required ICT equipment configuration states for calculating the cooling equipment's power are determined, thereby improving the accuracy of data estimation. For example, when the energy consumption of the cooling equipment is assessed for the first time, which is also the first estimation of the ICT equipment configuration states, only the current configuration state and full-load state of the ICT equipment in the data center are available. Therefore, the first ICT equipment configuration state at this time is the current configuration state of the ICT equipment in the data center, and the second ICT equipment configuration state is the full-load state.

[0099] Similarly, if the number of energy consumption assessments for the cooling equipment is greater than the preset target number, it indicates that there is currently data related to the estimated configuration status, and the configuration status of the second ICT equipment can be the estimated status.

[0100] Methods for determining the number of energy consumption assessments for cooling equipment may include: calculating the cooling power of each ICT device under its configuration state can be considered as one energy consumption assessment, and the number of energy consumption assessments can be determined based on the number of cooling power calculations.

[0101] The method for obtaining the power of the second ICT device and the second PUE may include: if the number of energy consumption assessments of the cooling device is less than or equal to a preset target number, then the configuration state of the second ICT device is determined to be at full load, the power of the second ICT device is the power of the fully loaded ICT device under full load, and the second PUE is the PUE under full load. If the number of energy consumption assessments of the cooling device is greater than the target number, then the configuration state of the second ICT device is determined to be in an estimated state, the power of the second ICT device is the power of the ICT device in the estimated state, and the second PUE is the PUE in the estimated state.

[0102] The method for determining the third PUE in the configuration state of the third ICT device in the computer room may include: calculating the third PUE by interpolation based on the power of the first ICT device, the first PUE, the power of the second ICT device, the second PUE, and the power of the third ICT device.

[0103] In this embodiment of the application, determining the third PUE of the data center in the configuration state of the third ICT device based on the power of the first ICT device, the first PUE, the power of the second ICT device, the second PUE, and the power of the third ICT device includes:

[0104] The difference between the power of the second ICT device and the power of the first ICT device is calculated to obtain the first difference value;

[0105] The difference between the power of the third ICT device and the power of the second ICT device is calculated to obtain the second difference value;

[0106] The difference between the second PUE and the first PUE is calculated to obtain the third difference value;

[0107] The first ratio is obtained by comparing the first difference and the second difference.

[0108] The first ratio and the third difference are multiplied to obtain the first product;

[0109] The product of the second PUE and the first PUE is summed to obtain the third PUE.

[0110] The calculation formula can be expressed as:

[0111] PUE3 = PUE2 + (W ICT2 -W ICT1 )×(PUE2-PUE1) / (W ICT3 -W ICT2 ),

[0112] Among them, PUE3 is the third PUE, W ICT1 For the first ICT device power, W ICT2 For the power of the second ICT equipment, W ICT3 The power of the third ICT device is PUE1, the first PUE is PUE2, and the second PUE is PUE2.

[0113] In this embodiment of the application, determining the power of the third cooling device in the third ICT device configuration state based on the third PUE and the power of the third ICT device includes:

[0114] Determine the product of the third PUE and the third ICT device power;

[0115] The power of the third refrigeration equipment is determined based on the difference between the product and the power of the third ICT equipment.

[0116] The formula for calculating the power of the third refrigeration unit can be:

[0117] W AIR3 =PUE3×W ICT3 -W ICT3 ,

[0118] Among them, W AIR3 This refers to the power of the third refrigeration unit.

[0119] In this embodiment, the third PUE is determined by the first PUE, the second PUE, and the power of the third ICT device, and the power of the third cooling device is determined by the third PUE. Thus, the power of the cooling device can be estimated using the two existing sets of data, avoiding actual ICT device configuration, accelerating calculation efficiency, and facilitating the evaluation of the impact of ICT device power on cooling device power, thereby reducing PUE and better reducing energy consumption.

[0120] S203. Based on the power of the third ICT device and the preset correspondence between the load rate and efficiency of the power conversion device, determine the input power of the power conversion device in the configuration state of the third ICT device.

[0121] Among them, power conversion equipment can refer to uninterruptible power supplies (UPS), which are used to provide uninterrupted power to some devices with high power stability requirements. In the embodiments of this application, the UPS is mainly used to provide power to ICT equipment.

[0122] The relationship between load rate and efficiency of power conversion equipment can be represented by a load rate-efficiency curve. The horizontal axis of the curve represents the load rate, and the vertical axis represents the efficiency. The load rate is the ratio of the power used to the rated power, and the efficiency is the ratio of the output power to the input power.

[0123] Methods for obtaining the relationship between load rate and efficiency of power conversion equipment may include: since load rate and efficiency need to be evaluated during the design of power conversion equipment, the relationship between load rate and efficiency can be obtained directly from the model of the power conversion equipment.

[0124] In this embodiment of the application, the input power of the power conversion device in the configuration state of the third ICT device is determined based on the power of the third ICT device and the preset correspondence between the load rate and efficiency of the power conversion device, including:

[0125] The output power of the power conversion equipment is determined based on the power of the third ICT device.

[0126] The load factor of the power conversion equipment is obtained by comparing its output power with its rated power.

[0127] The efficiency of the power conversion equipment is determined based on the load rate of the power conversion equipment and the relationship between the load rate and efficiency of the power conversion equipment.

[0128] The input power of the power conversion equipment in the second ICT equipment configuration state is determined based on the efficiency and output power of the power conversion equipment.

[0129] In this embodiment, since the power conversion device only supplies power to the ICT device, the power of the ICT device can be the output power of the power conversion device. By using the output power of the power conversion device and the correspondence between the load rate and efficiency of the power conversion device, the input power of the UPS can be accurately and efficiently determined, thereby improving the estimation efficiency.

[0130] S204. Determine the input power of the transformer in the configuration state of the third ICT equipment based on the input power of the power conversion equipment, the power of the third refrigeration equipment, and the preset correspondence between transformer load rate and efficiency.

[0131] Transformers can refer to devices that convert mains electricity into low-voltage electricity.

[0132] The relationship between transformer load factor and efficiency can be represented by a load factor-efficiency curve. The horizontal axis of this curve represents the load factor, and the vertical axis represents the efficiency. The load factor is the ratio of the power used to the rated power, and the efficiency is the ratio of the output power to the input power.

[0133] Methods for obtaining the relationship between transformer load rate and efficiency may include: since the load rate and efficiency need to be evaluated during the design of the transformer, the relationship between load rate and efficiency can be obtained directly from the transformer model.

[0134] In this embodiment, the input power of the transformer in the configuration state of the third ICT device is determined based on the input power of the power conversion equipment, the power of the third cooling equipment, and a preset correspondence between transformer load rate and efficiency. This includes:

[0135] The output power of the transformer is obtained by summing the input power of the power conversion equipment and the power of the third refrigeration equipment.

[0136] The load factor of the transformer is determined by comparing its output power with its rated power.

[0137] The efficiency of a transformer is determined based on its load factor and the corresponding relationship between its load factor and efficiency.

[0138] Based on the transformer's efficiency and the relationship between transformer load rate and efficiency, the input power of the transformer in the third ICT equipment configuration state is determined.

[0139] In this embodiment, since the transformer supplies power to the power conversion equipment and the cooling equipment, the sum of the input power of the power conversion equipment and the power of the cooling equipment can be the output power of the transformer.

[0140] S205. Determine the power supply status of the ICT power supply system under the configuration state of the third ICT device based on the input power of the transformer.

[0141] In this embodiment of the application, by determining the input power of the transformer, the power supply power of the ICT power supply system under the configuration state of the third ICT device can be determined. The power consumption of the ICT power supply system can be obtained through the power supply power. By evaluating the energy consumption under different ICT power levels, it is convenient to refine the operation, further improve the energy utilization rate, and reduce the energy consumption of the ICT power supply system.

[0142] This application provides a power determination method that determines the third PUE based on a first PUE, a second PUE, and the power of a third ICT device. The power of a third cooling device is then determined based on the third PUE. This allows for the estimation of the cooling device power using two existing sets of data, avoiding actual ICT device configuration and accelerating computational efficiency. It also facilitates the evaluation of the impact of ICT device power on cooling device power, leading to a lower PUE and better energy consumption reduction. By analyzing the correlation between the power of the third ICT device, the output power of the power conversion equipment, and the load rate and efficiency of the power conversion equipment, the input power of the UPS can be accurately and efficiently determined. The output power of the transformer is determined by summing the input power of the power conversion equipment and the power of the cooling device. Then, the input power of the transformer is further obtained through the correlation between the transformer's load rate and efficiency. By determining the transformer's input power, the power supply capacity of the ICT power supply system under the third ICT device configuration can be determined. This power supply capacity allows for the calculation of the ICT power supply system's energy consumption. Evaluating the energy consumption under different ICT configurations facilitates refined operation, further improving energy utilization and reducing the energy consumption of the ICT power supply system.

[0144] S301. Obtain the current power of ICT devices and the current power of air conditioners.

[0145] Methods for obtaining the current power of ICT equipment and the current power of air conditioning can include: real-time monitoring of the power data of ICT equipment (communication equipment and servers) and air conditioning in the data center. Related power monitoring instruments are also the standard configuration of ICT data centers.

[0146] S302. Determine the current PUE based on the current power of ICT equipment and the current power of air conditioning.

[0147] Based on the current power of ICT equipment and the current power of air conditioning, the current PUE of the data center can be calculated as (current power of ICT equipment + current power of air conditioning) / current power of ICT equipment.

[0148] S303. Determine the power of the ICT equipment to be estimated based on the current power of the ICT equipment.

[0149] Specifically, the power of the ICT equipment to be estimated is determined by identifying the power of the increased (or decreased) portion of the ICT equipment and the current power of the ICT equipment.

[0150] S304. Based on the power of the ICT equipment to be estimated, the current power of the ICT equipment, the current PUE, the power of the ICT equipment at full load, and the PUE at full load, the power of the air conditioner to be estimated is obtained.

[0151] The full-load power of the ICT data center can be obtained from the data center design, while the PUE at full load can be obtained from the actual measurement during the data center's completion and acceptance, or from the design calculation sheet; this calculation sheet is a necessary basis for the construction and approval of the data center.

[0152] If the air conditioning energy consumption is being assessed for the first time, the estimated PUE is calculated using interpolation based on the power of the ICT equipment to be estimated, the current power of the ICT equipment, the current PUE, the power of the ICT equipment at full load, and the PUE at full load. Then, the estimated air conditioning power is calculated based on the estimated PUE.

[0153] If the air conditioning energy consumption is assessed multiple times, the estimated PUE is calculated based on the two sets of ICT device power and PUE data that are closest to the estimated ICT device power, and the estimated air conditioning power is calculated based on the estimated PUE.

[0154] S305. Based on the estimated power of the air conditioner, the estimated power of the ICT equipment, the load rate-efficiency curve of the power conversion equipment, and the load rate-efficiency curve of the transformer, the input power of the transformer is obtained so as to estimate the power supply capacity based on the input power of the transformer.

[0155] For ICT data centers, the transformer output powers the UPS equipment and air conditioning; the UPS output powers the ICT equipment. Different loads can be calculated using a load factor-efficiency curve to determine the power output at the transformer or UPS input.

[0156] By calculating the estimated power of the ICT equipment and the estimated power of the air conditioner after the increase (decrease) of the ICT equipment, the power of the UPS input terminal can be obtained from the UPS efficiency curve. Then the power of the transformer output terminal is the sum of the estimated power of the air conditioner and the power of the UPS input terminal. The transformer input terminal can be obtained from the transformer efficiency curve, thereby simulating the power supply capacity after the increase (decrease) of the ICT equipment.

[0157] Another power determination method provided in this application involves determining the current Power Usage Effectiveness (PUE) based on the current ICT device power and the current air conditioner power. Then, based on the current ICT device power, the estimated power of the ICT device is determined. Finally, based on the estimated power of the ICT device, the current ICT device power, the current PUE, the fully loaded ICT device power, and the fully loaded PUE, the estimated power of the air conditioner is obtained. This yields the air conditioner power after the ICT device power changes, facilitating the determination of the air conditioner's power consumption. Finally, based on the estimated air conditioner power, the estimated ICT device power, the load factor-efficiency curve of the power conversion equipment, and the transformer load factor-efficiency curve, the transformer's input power is obtained. This allows for the estimation of power supply capacity based on the transformer's input power, enabling refined operation and reducing the energy consumption of the ICT power supply system.
