Description

Technical Field

[0001] This disclosure relates to power distribution systems, and more specifically to systems and methods for power distribution in data centers. Background Technology

[0002] Data centers are increasingly handling high-intensity computing tasks, including those driven by artificial intelligence (AI) and machine learning applications, which require massive processing power. As the computational demands of these applications fluctuate, they often cause power consumption spikes that can sometimes exceed power supply levels, for example, when using thousands of graphics processing units (GPUs) to train AI models such as Large Language Models (LLMs). These spikes can disrupt the stability of power generation and / or distribution, leading to power outages or even system failures. Traditional power distribution systems in data centers struggle to meet the power requirements of computing hardware due to the high intensity of tasks such as training AI systems, resulting in inefficiency and reduced system reliability.

[0003] Additionally, recent advancements in GPU and system design have increased rack power and computing density, often requiring impractical, thick supply cables and other power distribution components. These components tend to occupy significant space within server racks. Attached Figure Description

[0055] In the following description, numerous specific details are set forth to provide a more thorough understanding of at least one embodiment. However, it will be apparent to those skilled in the art that the inventive concept can be practiced without one or more of these specific details.

[0056] Some embodiments are best summarized in accordance with the claims of the specification.

[0057] Figure 1 An exemplary data center system 100 according to embodiments described herein is illustrated. In at least one embodiment, the data center components may be designed for the high computational demands of artificial intelligence / machine learning (AI / ML) and other high-performance computing (HPC) applications. In at least one embodiment, these data center components may be high heat density components requiring reliable and economical heat removal. In at least one embodiment, waste heat utilization (such as waste heat utilization in this heat recovery system) is suitable for data center cooling systems because these data center components generate a large amount of heat. In at least one embodiment, the heat recovery system of this invention, when used in a liquid cooling system for high heat density components, can improve data center efficiency and contribute to natural cooling within the data center. In at least one embodiment, such waste heat utilization reduces the environmental impact of data center cooling and reduces the carbon footprint of the data center.

[0058] In at least one embodiment, the exemplary data center infrastructure 100 may be as follows: Figure 1 As shown, the data center infrastructure has a cooling system improved as described herein. In at least one embodiment, the data center infrastructure 100 may be one or more rooms 1003 with racks 106 and auxiliary equipment for accommodating one or more servers on one or more server trays. In at least one embodiment, the data center infrastructure 100 is supported by a cooling tower 1005 located outside the data center infrastructure 100. In at least one embodiment, the cooling tower 1005 dissipates heat from within the data center infrastructure 100 by acting on a main cooling loop 1007. In at least one embodiment, one or more cooling distribution units (CDUs) 125 are used between the main cooling loop 1007 and a second or auxiliary cooling loop 1009 to enable heat extraction from the second or auxiliary cooling loop 1009 to the main cooling loop 1007. In at least one embodiment, in one aspect, the auxiliary cooling loop 1009 may access different pipes entering the server trays as needed throughout. In at least one embodiment, loops 1007, 1009 are shown as line diagrams, but those skilled in the art will recognize that one or more pipe features may be used. In at least one embodiment, flexible polyvinyl chloride (PVC) pipes can be used with an associated piping system to allow fluid to move along each of loops 1007, 1009. In at least one embodiment, one or more coolant pumps can be used to maintain pressure differentials within loops 1007, 1009, allowing coolant to move according to temperature sensors in different locations, including in a room, in one or more racks 106, and / or in server enclosures or server trays within racks 106.

[0059] In at least one embodiment, the coolant in the main cooling circuit 1007 and the auxiliary cooling circuit 1009 may be at least water and additives, such as ethylene glycol or propylene glycol. In operation, in at least one embodiment, each of the main cooling circuit and the auxiliary cooling circuit has its own coolant. In at least one embodiment, the coolant in the auxiliary cooling circuit may be dedicated to the requirements of components in the server tray or rack 106. In at least one embodiment, one or more CDUs 125 are capable of complex control over the coolant in circuits 1007, 1009, independently or simultaneously. In at least one embodiment, the CDUs may be adapted to control the flow rate so that the coolant is appropriately distributed to absorb heat generated within the rack 106. In at least one embodiment, additional flexible conduits 1015 are provided from the auxiliary cooling circuit 1009 to enter each server tray and supply coolant to electrical and / or computing components.

[0060] In at least one embodiment, electrical and / or computing components are interchangeably used to refer to heat-generating components that benefit from the data center cooling system. In at least one embodiment, tubing 1019 forming part of auxiliary cooling loop 1009 may be referred to as a room manifold. Individually, in at least one embodiment, tubing 1017 extending from tubing 1019 may also be part of auxiliary cooling loop 1009, but may be referred to as a row manifold. In at least one embodiment, tubing 1015 enters a rack as part of auxiliary cooling loop 1009, but may be referred to as a rack cooling manifold. In at least one embodiment, row manifold 1017 extends along rows in data center infrastructure 100 to all racks. In at least one embodiment, the piping of auxiliary cooling loop 1009 including manifolds 1019, 1017, and 1015 may be improved by at least one embodiment of this disclosure. In at least one embodiment, a chiller 1021 may be provided in the main cooling loop within data center infrastructure 100 to support cooling prior to cooling tower 1005. In at least one embodiment, to the extent that additional circuits exist in the main control circuit, those skilled in the art will recognize upon reading this disclosure that these additional circuits provide cooling outside the rack and outside the auxiliary cooling circuits; and may be combined with the main cooling circuit used in this invention.

[0061] In at least one embodiment, during operation, heat generated within the server trays of rack 106 can be transferred to coolant exiting rack 106 via flexible tubing of rack manifold 1015 of auxiliary cooling circuit 1009. In at least one embodiment, a second coolant (in auxiliary cooling circuit 1009) from one or more CDUs 125 for cooling rack 106 moves toward rack 106. In at least one embodiment, the second coolant from one or more CDUs 125 is transferred from one side of chamber manifold with tubing 1019 to one side of rack 106 via row manifold 1017 and through tubing 1015 to one side of server tray. In at least one embodiment, used or returned second coolant (or departing second coolant that carries heat away from computing components) exits from the other side of server tray (e.g., after circulating through server tray or through components on server tray, entering the left side of rack for server tray and exiting the right side of rack). In at least one embodiment, the used second coolant exiting the server tray or rack 106 exits from different sides (such as the outlet side) of the conduit 1015 and moves to the parallel, also outlet side, of the row manifold 1017. In at least one embodiment, the used second coolant moves from the row manifold 1017 in a parallel portion of the chamber manifold 1019, traveling in the opposite direction to the incoming second coolant (which may also be a newer second coolant), and toward one or more CDUs 125.

[0062] In at least one embodiment, the used second coolant exchanges its heat with the main coolant in the main cooling circuit 1007 via one or more CDUs 125. In at least one embodiment, the used second coolant can be refreshed (e.g., when relatively cooled compared to the temperature of the used second coolant stage) and prepared for back-circulation through the auxiliary cooling circuit 1009 to the computing unit. In at least one embodiment, various flow and temperature control features in one or more CDUs 125 enable control of the heat exchange from the used second coolant or the inflow and outflow of the second coolant from one or more CDUs 125. In at least one embodiment, one or more CDUs 125 may also be able to control the flow of the main coolant in the main cooling circuit 1007.

[0063] In at least one embodiment, the main cooling circuit 1007 and the auxiliary cooling circuit 1009 are different from the single-phase cooling circuit and the two-phase cooling circuit (or path) as described below. In at least one embodiment, the single-phase cooling circuit and the two-phase cooling circuit (or path) as described below may be part of the auxiliary cooling circuit 1009. Thus, in at least one embodiment, the data center infrastructure 100 as described herein may have three different cooling circuits.

[0064] In at least one embodiment, the data center system 100 may be powered by a power grid system supplying alternating current (AC) power (e.g., 240-277V). In at least one embodiment, the conventional power delivery structure at the data center system 100 may additionally incorporate batteries, which are typically charged separately and may only be used to power the server racks 106 when the power grid fails (e.g., during a power outage). Thus, when the data center system 100 is powered by AC power, the batteries may be idle and therefore underutilized.

[0065] In at least one embodiment, a conventional power delivery structure may have one or more power factor correction (PFC) modules located at the server rack 106 for converting AC power supply to DC power within the server rack 106. In at least one embodiment, such PFC modules in a conventional setup may occupy a significant amount of space on the server rack 106.

[0066] In at least one embodiment, the data center system 100 can handle high-intensity computing tasks, such as training AI models by servers placed on rack 106, which requires significant processing power. In at least one embodiment, the current AC power supply (e.g., at 240-277VAC) may not be scalable to meet such high power demands. Furthermore, due to the batch-synchronous nature of AI workloads (e.g., when using thousands of graphics processing units (GPUs) to train large language models (LLMs), the server rack 106 may cause workload fluctuations on the power grid. These fluctuating and high-intensity workloads may disrupt power distribution stability within the data center 100, potentially leading to power outages or even system failures. In at least one embodiment, due to the high-intensity tasks such as training AI systems, traditional power supply in the data center (e.g., 240-277V AC power) may be insufficient to meet the power requirements of the computing hardware, resulting in inefficiency and reduced system reliability.

[0067] Figure 2A A schematic diagram of a power distribution system 200 for a data center system (e.g., data center infrastructure 100) according to at least one embodiment is illustrated. In at least one embodiment, such as Figure 2A As shown, a data center system can have separate spaces for power and computing, such as a power room 201 that receives power directly from power sources 202 and 204, and a separate computer room 200 that hosts server racks 106 and associated computing hardware.

[0068] In at least one embodiment, the power room 201 may house one or more converter racks 205 that receive power from a main power source 202 or an auxiliary power source 204, as well as other power sources / power supplies into which power can be introduced. In at least one embodiment, the main power source 202 may include a grid system that supplies AC power (e.g., 240-277V AC) from a utility provider. In at least one embodiment, the auxiliary power source 204 may provide backup power in the event of a power failure supplied by the main power source 202. In at least one embodiment, the auxiliary power source 204 may include any one or more of the following: a diesel generator, a natural gas generator, a battery-powered system, a fuel cell system, a microgrid system, a solar system, a nuclear system, a wind system, or any other type of power source.

[0069] In at least one embodiment, the main power supply 202 and the auxiliary power supply 204 may be selectively connected to the converter rack 205 via a switch 206. In at least one embodiment, the main power supply 202 and the auxiliary power supply 204 may individually or simultaneously introduce supplied power into the converter rack 205.

[0070] In at least one embodiment, the converter rack 205 may include a PFC circuit 210 that converts supplied AC power to DC power. Conventionally, AC-to-DC conversion can be performed at the rack level at server rack 106. In at least one embodiment, by housing the PFC circuit 210 in a converter rack 205 that is separate from and located outside rack 106, rack space can be reserved for accommodating computing hardware, allowing rack 106 to be compute-intensive and facilitating interconnection. This allows for higher computing density to be achieved at rack 106 within the computing room 200.

[0071] In at least one embodiment, the converter rack 205 may further include a constant current source 215 that receives converted DC power from the PFC circuit 210 and supplies high-voltage DC to the busway 222 outside the power room 201. In at least one embodiment, by housing the PFC circuit 210 and the constant current source 215 together with the converter rack 205 in a separate computer room 201, the cables across the busway 222 can deliver high-voltage DC, rather than AC in a conventional system where AC power is delivered directly to the server rack 106 and converted to DC only at the server rack 106. For example, the high-voltage DC (e.g., 800VDC) may be at least twice the maximum voltage of the AC power supply (e.g., 240-277VAC). In this way, the power cables used for busbar 222 can be much thinner than the power cables that transmit AC power to rack 106 in conventional power transmission systems. For example, the diameter of a power cable that transmits high-voltage DC power of about 800VDC is only 1 / 3 of the diameter of a power cable that transmits AC power of about 240-277VAC.

[0072] In at least one embodiment, the computing room 200 may accommodate one or more computer racks 106. In at least one embodiment, the computer rack 106 may receive high-voltage DC via busbar 222. In at least one embodiment, the computer rack 106 may be compute-intensive (where there is no PFC circuitry on the rack) and may also include one or more converters 212 for converting the received high-voltage DC to a lower voltage (e.g., 54VDC) to serve the computing hardware on the rack 106. It should be fully understood that various embodiments may use various AC and DC voltage levels, and the examples provided herein are not intended to limit or constrain this disclosure.

[0073] In at least one embodiment, the computing room 200 may also accommodate one or more batteries 216, for example, placed on one or more racks. In at least one embodiment, the batteries 216 may be connected via busbar 222 to receive high-voltage DC from the converter rack 205 for charging. In at least one embodiment, the batteries 216 may also be connected via busbar 222 to supply DC to the rack 106 while discharging. In this way, the batteries 216 can be continuously utilized.

[0074] In at least one embodiment, the data center controller 218 may be communicatively coupled to a converter rack 205 in the power room 201, a battery 216 in the computing room 200, and / or a server rack 106. In at least one embodiment, the data center controller 218 may be housed inside or outside the computing room 200. In at least one embodiment, the data center controller 218 may be located at the building management system (BMS) of the power room 201 and the computing room 200. In at least one embodiment, the data center controller 218 may be located remotely from the power room 201 and / or the computing room 200 and accessed via a network.

[0075] In at least one embodiment, the data center controller 218 may be communicatively coupled between the server rack 106, the battery 216, and the converter rack 205. In at least one embodiment, the data center controller 218 may receive a signal from the battery 216 indicating the battery state of charge (SOC) 220 (e.g., charge percentage (e.g., 20%, 30%, etc.)). In at least one embodiment, the data center controller 218 may send control signals 224 to the rack 216 to set the rack power based on the state of charge 220 and / or the minimum charge level of the battery uninterruptible power supply (UPS).

[0076] In at least one embodiment, the data center controller 218 may also send control signals 225 to the converter rack 205 to set the grid power based on the battery charging state 220 and / or a target charging level (e.g., 60%, 70%, etc.), such as how much power to draw from the grid 202 or the alternative power source 204. The following can be combined with... Figure 2B The additional power control operations of the data center controller 218 are described.

[0077] In at least one embodiment, the data center controller 218 may include or be coupled to one or more control panels 415. In at least one embodiment, as described below... Figure 2B and Figure 4 As further explained, control panel 415 can be configured to change Figure 2A The diagram shows the power distribution system settings, mode changes, threshold settings (such as battery SoC target level 226, minimum SoC required for UPS 227, etc.), function activation, and other ways to control the power distribution system.

[0078] The following text is about Figure 3Further discussion is given of example embodiments of scenarios where the data center controller 218 can selectively direct DC power to server racks and charge batteries. These example embodiments are not intended to limit this disclosure, but rather to illustrate how a power distribution system can dynamically adapt to and serve variable power loads, thereby reducing power curtailment, ensuring the continuity and stability of power delivery, stabilizing the data center's demand on the power grid, and other advantages.

[0079] Figure 2B The illustration shows an embodiment according to the description herein. Figure 2A A simplified diagram of example operations of the data center controller 218 in setting rack power and / or grid power. In at least one embodiment, the data center controller 218 may include a first proportional-integral-derivative (PID) controller 218a and / or a second PID controller 218b, the first PID controller 218a setting grid power 225 at converter circuit 205 (e.g., how much power to draw from grid 202 or alternative power source 204), the constant current source 215 outputting a constant current to bus 222 based on the grid power 225; the second PID controller 218b setting rack power limits 224 (e.g., how much power to deliver to server rack 106 so that computing hardware on server rack 106 operates within these power limits). In at least one embodiment, the PID controllers 218a-218b may receive inputs based on one or more of the following: a target battery SoC 226 (e.g., a threshold at which battery 216 may stop charging, such as 60%, 70%, 80%, etc.), a real-time measured battery SoC 220, and / or a minimum SoC 227 of the battery UPS.

[0080] For example, in at least one embodiment, the PID controller 218a may receive the difference between the target battery SoC 226 (e.g., a threshold at which battery 216 can stop charging, such as 60%, 70%, 80%, etc.) and a real-time measured battery SoC 220 as input 219a. In at least one embodiment, the PID controller 218a may generate a PID output based on a proportional term proportional to the difference, an integral term depending on the cumulative sum of past differences, and a derivative term depending on the rate of change of the difference, in order to provide correction based on how quickly the error changes. In at least one embodiment, the PID output may therefore be a weighted sum of the difference, the cumulative past differences, and the rate of change of the difference. In at least one embodiment, the PID output may be used to set the grid power 225. In at least one embodiment, for example, the set grid power 225 may be adjusted in response to input 219a (e.g., when the measured battery SoC 220 is significantly lower than the target SoC 226 (battery 216 is undercharged and needs charging)). The proportional term of the PID output may have the greatest impact, thus the resulting set grid power 225 can be adjusted to accelerate battery charging while supporting server rack 206. In at least one embodiment, for example, the derivative term of the PID output may become more significant when the difference changes rapidly (e.g., battery SoC 220 increases rapidly), thereby producing a set grid power 225 to slow down battery charging. In at least one embodiment, other types of control mechanisms (such as algorithmic controllers, rule-based controllers, neural network models, etc.) may be used to set the grid power 225 in response to input 119a.

[0081] In at least one embodiment, the data center controller 218 may include a second PID controller 218b that sets a rack power limit 224 (e.g., how much power is delivered to server rack 106 so that the computing hardware on server rack 106 operates within that power limit). For example, the computing hardware at server rack 106 may need and therefore draw more total power from power supplies 202 and / or 204 than the total power already provisioned to the data center, for example, when the computing hardware is under heavy workloads and / or power spikes occur. In this case, the data center controller 218 may reduce the rack power limit 224 so that the total rack power can be adjusted to meet the supply; and the reduced power limit 224 may also prevent the battery 216 from being depleted too deeply. In at least one embodiment, the PID controller 218b may receive a real-time measured difference between the battery SoC 220 and the minimum SoC 227 of the battery UPS as input 219b and generate a PID output representing the set rack power 224. In at least one embodiment, the PID controller 218b can generate a PID output based on a proportional term proportional to the difference, an integral term depending on the cumulative sum of past differences, and a derivative term depending on the rate of change of the difference, in order to provide correction based on how quickly the error changes. In at least one embodiment, the PID output can therefore be a weighted sum of the difference, the cumulative past differences, and the rate of change of the difference. In at least one embodiment, the PID output can be used to set the rack power limit 224. In at least one embodiment, for example, the rack power 224 can be set in response to input 219b (e.g., when the measured battery SoC 220 is much higher than the minimum SoC 227 of the UPS (battery 216 is fully charged to act as supplementary power)), where the proportional term of the PID output may have the greatest impact, and thus the resulting rack power limit 224 can be adjusted higher to receive supplementary power from the discharge of battery 216. For another example, when the measured battery SoC 220 is lower than the minimum SoC 227 of the UPS (meaning that battery 216 cannot discharge to provide supplementary power), the resulting rack power limit 224 can be adjusted lower. In at least one embodiment, for example, when the difference changes rapidly (e.g., the battery SoC 220 decreases rapidly), the derivative term of the PID output may become more significant, thereby generating rack power limitation 224 to slow battery discharge. In at least one embodiment, other types of control mechanisms (such as algorithmic controllers, rule-based controllers, neural network models, etc.) may be used to set rack power 224 in response to input 119b.

[0082] In at least one embodiment, a neural network model (such as a Long Short-Term Memory (LSTM) model) can be trained to generate outputs setting grid power 225 and setting rack power 224 in response to inputs including the minimum SoC 227 of the UPS, the target level 226 of the battery SoC, and the real-time measured battery SoC 220. For example, the neural network model can receive training inputs describing historical data (including the minimum SoC 227 of the UPS, the target level 226 of the battery SoC, and historical battery SoC 220) and generate training outputs of predicted grid power and rack power. A loss is calculated by comparing the predicted grid / rack power with the actual grid / rack power from the historical data. This loss can be used for backpropagation and training of the LSTM neural network. [The remaining text appears to be incomplete and requires further context.] Figure 19 Further, additional embodiments for training neural networks were found.

[0083] In at least one embodiment, a time-series neural network model may be employed to receive input of time-series data over a period of time, representing the SoC level over time, the workload at server rack 106, etc. In at least one embodiment, various input factors may be converted into tokens and concatenated into an input sequence for input to the neural network, which in turn generates a predicted time-series output of rack power constraints and / or grid power over future time periods.

[0084] In at least one embodiment, a large language model (LLM) may be employed to receive text input describing the user configuration of the SoC level, the battery SoC target level 226, and / or the minimum SoC 227 and / or power control target of the UPS, and to generate outputs describing power setting parameters describing the grid power 225 and / or rack power 224.

[0085] In at least one embodiment, the neural network model can be implemented at a server communicatively coupled to the data center controller 218, such as... Figure 4 As shown.

[0086] Thus, as Figure 3As further illustrated, by setting the grid power 225 and the rack power 224, the battery 216 can periodically charge and discharge to create supplemental power for the server rack to meet the high power demands of computing hardware (such as GPUs) placed on the server rack 106. This periodic power cycling of the rack power level can serve the batch-synchronous nature of AI workloads (e.g., during AI system training), which may experience periods of low power demand when the GPU is loading training data, followed by periods of high power demand when the GPU is performing complex computations during training; and these high-low demand periods can be repeated as training iterations are repeatable. In at least one embodiment, with the data center controller 218 coordinating the charging and discharging of the battery 216 and setting rack power limits for the rack 106, power profiles from the compute room 200 can be smoothed, even given the batch-synchronous nature of AI workloads.

[0087] Figure 2C The illustration shows a schematic diagram of a power distribution system for a data center system (e.g., data center infrastructure 100) according to at least one embodiment. In at least one embodiment, as Figure 2C As shown, the data center system can be supplied with three-phase AC power from the power grid 202, as indicated by phases 202a, 202b, and 202c. In at least one embodiment, at least one power factor correction circuit (e.g., power factor correction circuit 210) can be configured to generate positive and negative voltage outputs. In at least one embodiment, the positive and negative voltage outputs jointly supply power to one or more server racks (e.g., server rack 106) and / or one or more batteries (e.g., battery 216). In at least one embodiment, the positive voltage output from the power factor correction circuit 210 can be 400V, and the negative voltage output can be -400V, thereby providing 800VDC to the computing room. It should be understood that these voltages can have different levels, and the scope of this disclosure is not limited to 400V, -400V, and 800VDC. In at least one embodiment, the jointly supplied power can be a symmetrical voltage supply, while in other embodiments, the jointly supplied power can be an asymmetrical voltage supply.

[0088] In at least one embodiment, such as Figure 2CAs shown, the power distribution system may exclude the neutral cable from the power converter circuit (e.g., power converter circuit 205) to the server rack and / or battery. Thus, in at least one embodiment, without a neutral cable, the power distribution system delivers high-voltage (e.g., 800VDC) power through thin cable laying and by reducing the number of cables. In at least one embodiment, power can be supplied from the power factor correction circuit 210 to the computing room (e.g., computing room 200) via only two cables, thereby reducing the thickness of the cable laying and the volume and weight of the required components.

[0089] Figure 2D The illustration shows a schematic diagram of a power distribution system for a data center system (e.g., data center infrastructure 100) according to at least one embodiment. In at least one embodiment, the power distribution system can be integrated with... Figure 2C The power distribution system shown is similar, but it may include a neutral cable from a power converter circuit (e.g., power converter circuit 205) to server rack 106 and / or battery 216. In at least one embodiment, the power converter circuit includes one or more isolated power factor correction circuits 210. In at least one embodiment, each phase of the AC power supply phases 202a, 202b, and 202c may be supplied to each isolated power factor correction circuit 210. In at least one embodiment, server rack 106 may include one or more power supply units (PSUs). In at least one embodiment, each PSU may take a positive or negative 400V as input and output a lower DC voltage necessary for the operation of server rack 106.

[0090] Figure 3 The illustration shows an illustration according to at least one embodiment. Figure 2A The example plot shows the power supply level (grid) and rack power level within the power distribution system over time. In at least one embodiment, as shown... Figure 3 As shown, the x-axis of the plot can represent time, while the y-axis can represent power level. In at least one embodiment, the solid curve 310 represents a rack (e.g., Figures 1-2A The power level at point 106 in the figure, and the dashed curve 320 represents the power level from the power source (e.g., Figure 2A The AC power level supplied by 202 or 204 in the middle.

[0091] In at least one embodiment, starting from an idle period 301, for example, when the AC power is off, a ramp-up period 302 may be observed where the AC power level 320 increases to its steady state. Once steady state 303 is reached, the AC power level 320 can remain largely constant. In at least one embodiment, the rack power level 310 may experience periodic peaks and troughs 308 when the data center controller 218 selectively causes the battery to cycle through discharge and charge. For example, in at least one embodiment, the rack power level 310 may experience a peak when the battery 216 is discharging to provide supplemental power to the rack 106. In at least one embodiment, the rack power level 310 may drop to a level similar to the AC power level when the data center controller 218 determines that the state of charge at the battery indicates that the battery can no longer be discharged. In at least one embodiment, the rack power level 310 may experience a trough when at least a portion of the AC power is directed to charge the battery.

[0092] In at least one embodiment, the periodicity of rack power level 310 can serve the batch synchronization characteristics of the AI ​​system's computational workload (such as during training). In at least one embodiment, rack power level 310 can therefore serve fluctuations in power demand at the rack. Thus, while AC power level 320 remains constant, this AC power can be used to power server racks that may require even higher peak power levels than data center power level 320. Power distribution and utilization efficiency at the data center system is improved.

[0093] In at least one embodiment, the steady-state period 303 can be terminated when the workload at the rack ends and / or a system failure occurs (e.g., server crash, etc.). In at least one embodiment, the server rack power level 310 can therefore drop sharply to zero, but the AC power supply 320 will have a ramp-down period 304 that decreases to zero, followed by an idle period 305.

[0097] In at least one embodiment, control unit 406 may send one or more control signals to automatically and / or periodically adjust the power distribution configuration (e.g., power supply, power factor correction, operating mode, power distribution scheduling) and power consumption configuration (e.g., power load, power load scheduling) at the power distribution system 200. In at least one embodiment, a user may input and / or design one or more different combinations of power distribution and power consumption configurations via user interface 410 of user equipment 408. In at least one embodiment, control unit 406 may automatically generate one or more different power distribution / power consumption configurations (e.g., via a neural network, via one or more predefined rules).

[0098] In at least one embodiment, configuration parameters may be received by a control panel 215 at a power distribution system 200, which in turn may send control signals to control the circuits and controllers of the power distribution system 200 (e.g., power supply circuit 201, power factor correction circuit 210, power factor correction circuit 212, power controller 218).

[0099] In at least one embodiment, the power distribution system 200 may include one or more sensors 412. The sensors 412 may collect measurement results based on operating parameters. In at least one embodiment, the collected measurement results may include voltage levels from voltage sensors, current quantity and current type from current sensors, power quantity and power type from power sensors, temperature from temperature sensors, phase and frequency from phase and frequency sensors, faults from fault detection sensors, and other measurement results from other sensor types.

[0100] In at least one embodiment, the power distribution system 200 may transmit one or more collected measurement results to the control unit 406 via network 430. In at least one embodiment, the control unit 406 may configure the power distribution system 200 (e.g., by reconfiguring operating parameters based on the collected measurement results to meet power distribution objectives). In at least one embodiment, the control unit 406 may store a history of past operating parameters and measurement results in memory. In at least one embodiment, sensor measurement results indicating the power distribution and power consumption performance of different power distribution and power consumption devices representing different types of computing hardware may be displayed via user interface 410 of user equipment 408.

[0101] In at least one embodiment, the control unit 406 can analyze the collected measurement results to make a decision. For example, in at least one embodiment, the control unit 406 can construct a training dataset of power distribution and power consumption configurations. In at least one embodiment, such a training dataset can be stored in a data memory 419. In at least one embodiment, the data memory 419 can be located in the same or a different location than the control unit 406.

[0102] In at least one embodiment, the control unit 406 can train a neural network-based model using a training dataset. In at least one embodiment, the neural network-based model can use operating parameters of the power distribution system 200 as input and predict power distribution or power consumption performance, such as future / optimal power supply levels, future / optimal power distribution scheduling, etc. In at least one embodiment, the neural network-based model can be trained to generate a predicted output indicating whether correction is needed and, if so, what a new configuration set might be. In at least one embodiment, based on collected measurements, one or more trained neural networks can be trained to adjust one or more power and consumption parameters to collect new allocation and consumption data. In at least one embodiment, upon obtaining power distribution or power consumption data from the power distribution system 200, the control unit 406 can train a neural network model to predict power consumption scheduling based on one or more batteries 216 and / or one or more server racks 208 in the power distribution system 200.

[0103] In at least one embodiment, the control unit 406 may use a lookup table to generate a new power distribution and power consumption procedure set, which maps the measured set of power distribution and power consumption conditions to a predefined set of power distribution and power consumption settings. In at least one embodiment, the new power distribution and power consumption procedure set may take a formatted sequence of actions to configure the thermal settings, power settings, and coolant settings of the data center infrastructure 100. In at least one embodiment, the thermal settings, power settings, and coolant settings can be configured via the power distribution procedure.

[0104] In at least one embodiment, the operating parameters of server 208, such as thermal settings, power settings, and coolant settings, can be updated based on a new configuration of power distribution system 200. For example, after control unit 406 can send a new power configuration set to power distribution system 200, the input power level of power supply circuit 201 can be reduced, thereby also reducing the input power level of server 208. In at least one embodiment, after power distribution system 200 approves the update, control unit 406 can send an instruction to control panel 215 to update the operating parameters of power distribution system 200. In at least one embodiment, the instruction to update the operating parameters of server 208 can be sent directly to server 208.

In at least one embodiment, control unit 406 can send the generated rack power 224 and grid power 225 back to controller 218. In at least one embodiment, sensor input from sensor 412 can be fed as part of the input to the neural network to generate the predicted rack power 224 and / or grid power 225.

[0106] Figure 5 The illustration shows an illustration of a method for use according to at least one embodiment. Figures 2A-2B The flowchart illustrates the power distribution operation of a data center system. One or more processes in method 500 may be implemented, at least in part, in the form of executable code stored on a non-transitory, tangible, machine-readable medium, which, when run by one or more processors, causes one or more processors to execute one or more processes within the process. One or more processes in method 500 may be implemented by one or more power control circuits (e.g., data center controller 218), one or more power factor correction circuits (e.g., power factor correction circuits 210, 212), and / or one or more control units (e.g., control unit 406). As illustrated, method 500 includes a plurality of enumerated steps, but aspects of method 500 may include additional steps before, after, and between the enumerated steps. In some aspects, one or more of the enumerated steps may be omitted or performed in a different order.

[0107] In at least one embodiment, method 500 may be performed to selectively enable the power supply (e.g., based at least in part on one or more charging levels (e.g., SoC 220) corresponding to one or more batteries (e.g., 216) to at least partially enable the power supply (e.g., Figure 2A At least a portion of the DC power at bus 222 in the system is directed to one or more server racks (e.g., in...). Figure 2A (106) or one or more batteries (e.g., Figure 2A The battery 216 in the middle is being charged.

[0108] In at least one embodiment, at step 502, a DC current can be output at a high voltage (e.g., 800VDC) (e.g., from constant current source 215), which is subject to a set grid power. For example, constant current source 215 can receive the set grid power from data center controller 218.

[0109] In at least one embodiment, at step 504, a power controller circuit (e.g., data center controller 218) may monitor the battery charge level status (e.g., 220) from one or more batteries (e.g., 216). For example, at least one of the power controller circuits is communicatively coupled between at least one server rack in one or more server racks (e.g., 106) and at least one power converter circuit (e.g., 205), the at least one power converter circuit including at least one power factor correction circuit (e.g., 210) located outside the one or more server racks (e.g., 106).

[0110] In at least one embodiment, at step 506, at least one of the power controller circuits is configured to send one or more control signals to one or more server racks to set the power of one or more racks (e.g., 224) based on one or more charging levels (e.g., 220) and one or more minimum charging levels (e.g., 227) of the uninterruptible power supply (UPS). For example, one or more minimum charging levels (e.g., 227) may be configured as constant parameters by the user, algorithm, and / or system.

[0111] In at least one embodiment, at step 508, at least one power controller circuit of one or more power controller circuits is configured to send one or more control signals to the converter circuit to set one or more grid power (e.g., 225) based on one or more charging levels (e.g., 220) and one or more target charging levels (e.g., 226). For example, at steps 506 and / or 508, at least one power controller circuit of one or more power controller circuits is configured to set one or more rack power of one or more server racks via one or more of the following: one or more user inputs, one or more proportional-integral-derivative (PID) control circuits (e.g., 218a-b), or one or more neural networks trained on historical power control data of one or more server racks.

[0112] In at least one embodiment, at step 510, at least one of the power controller circuits is further configured to selectively cause a first portion of the power supply to charge one or more batteries and a second portion of the power supply to be directed to one or more server racks when the power supply is greater than the total rack power.

[0113] In at least one embodiment, at step 512, at least one of the power controller circuits is further configured to selectively direct the power supply and supplementary power from discharging from one or more batteries to one or more server racks when the power supply is lower than the total rack power.

[0114] In at least one embodiment, steps 510 and 512 may occur alternately, such that one or more batteries are alternately charged and discharged based at least in part on one or more charging levels. Thus, one or more server racks are powered by an alternating current (AC) power supply at a power level lower than the peak power level of one or more server racks.

[0115] In at least one embodiment, continuing from step 510 and / or 512, method 500 may loop back to step 504 and repeat steps 504-512.

[0116] In at least one embodiment, it should be understood that steps 502-512 may not necessarily be performed in accordance with the prescribed procedure. Figure 5The exemplary sequence shown occurs, but it can occur simultaneously and / or sequentially or in any other order. For example, step 504 can occur periodically, intermittently, and / or concurrently with steps 506-512. As another example, steps 506 and 508 can be performed simultaneously, or one step can be performed more frequently than the other. For yet another example, steps 510 and 512 can occur periodically and / or alternately.
