Description

TECHNICAL FIELD

[0002] As the core infrastructure supporting the operation of IT (Information Technology) servers and network devices, the power supply of a data center relies on a municipal power resource pool. The power resources are mainly divided into three major loads within the data center: IT device operation, computer room refrigeration air conditioning system, and building auxiliary supporting facilities. Among them, the IT device capacity directly reflects the effective output value of the data center, so improving the IT device carrying capacity under the same municipal power capacity has become the core indicator of power resource utilization efficiency.

[0003] However, the operating power of air conditioning equipment presents significant time periodic fluctuations, especially in high-temperature seasons or peak business periods, the power demand rises sharply, causing the municipal power capacity to face overload risk in critical periods. Such fluctuations not only limit the expansion space of IT devices, but also force the data center to maintain redundant power configuration during off-peak periods, resulting in idle resources.

Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solutions of this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0026] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein.

[0027] The following exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided to make this disclosure more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a full understanding of embodiments of this disclosure. However, those skilled in the art will recognize that the technical solutions of this disclosure can be practiced with one or more of the specific details omitted, or other methods, components, apparatus, steps, etc., can be employed.

[0028] Furthermore, the accompanying drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted. Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0029] In some related embodiments, a combination of UPS (Uninterruptible Power Supply) and backup batteries can be used to provide uninterrupted power to IT equipment and cooling equipment.

[0030] Figure 1 A schematic diagram of backup battery charging under normal mains power supply conditions is shown in one related embodiment of this disclosure. Under normal mains power supply conditions, the backup battery is charged through the UPS, while simultaneously supplying power to the load.

[0031] Figure 2 A schematic diagram of backup battery discharge in the event of a mains power failure is shown in a related embodiment of this disclosure. In the event of a mains power failure, the backup battery pack discharges to supply power to the load and provide uninterrupted power.

[0032] In the relevant embodiments, the overall solution is a backup power logic. The battery only discharges when the mains power fails, ensuring power supply stability, but it does not help with IT resource output.

[0033] Based on the above problems, this exemplary implementation first provides a power supply control method. (Reference) Figure 3 As shown, the above power supply control method may include the following steps: Step S310. Determine the power balance point of the air conditioning equipment within the target time period based on the operating power of the air conditioning equipment in each time period within the historical time period corresponding to the target time period.

[0034] Step S320. When the operating power of the air conditioning equipment during the target time period is less than or equal to the power balance point, the air conditioning equipment is supplied with power through the basic power resource pool, and the energy storage battery on the uninterruptible power supply is charged.

[0035] Step S330. When the operating power of the air conditioning equipment is greater than the power balance point within the target time period, the air conditioning equipment is jointly powered by the energy storage battery and the basic power resource pool.

[0036] In the power supply control method of the exemplary implementation of this disclosure, the power balance point is dynamically determined based on historical operating data, and the mode of independent power supply from the basic power resource pool or joint power supply with the energy storage battery is intelligently switched according to the comparison result of real-time operating power and balance point. This achieves refined regulation of power load, can dynamically identify the power balance point, coordinate the power supply strategies of the basic power resource pool and the energy storage battery, effectively shaving peaks and filling valleys, avoid the risk of municipal power overload, optimize power resource utilization, and reduce resource idleness.

[0037] Below, in conjunction with Figures 4 to 12 The steps described above in this example implementation will be explained in more detail.

[0038] In step S310, the power balance point of the air conditioning equipment in the target time period is determined based on the operating power of the air conditioning equipment in each time period of the historical time period corresponding to the target time period.

[0039] In this example implementation, the target time period refers to the specific time period for which power supply control is required. The historical time period corresponding to the target time period serves as a reference period, such as the current date being the same date in different past years, or the day before the current date. The power balance point is a dynamic threshold used to distinguish the operating load state of the air conditioning equipment. Specifically, it can be determined using statistical methods of operating power in various time periods within the historical time period. Its main purpose is to accurately characterize the load characteristics within the target time period, avoiding insufficient strategy adaptability due to fixed thresholds. Setting the power balance point based on the temporal distribution characteristics of historical loads can accurately capture the periodic patterns of air conditioning operation, such as diurnal or seasonal variations, thereby avoiding strategy failures caused by fixed thresholds and providing a reliable benchmark for power supply decisions.

[0040] In this example implementation, the air conditioning equipment can be powered by a UPS. The UPS can be combined with an energy storage battery, which can be charged during off-peak hours and discharged during peak hours.

[0041] Figure 4 A schematic diagram of a charging process for an energy storage battery according to a specific embodiment of this disclosure is shown. Figure 5 A schematic diagram of a combined discharge of an energy storage battery in one specific embodiment of this disclosure is shown. During peak electricity demand, the energy storage battery can work in conjunction with the mains power to supply power to the load, reducing the capacity supply on the power supply side.

[0042] In this example implementation, the energy storage battery includes energy storage capacity and emergency capacity. The air conditioning capacity can be analyzed according to the equipment type of the air conditioning equipment, and the energy storage capacity of the energy storage battery can be determined based on the air conditioning capacity analysis results.

[0043] Energy storage capacity refers to the portion of capacity used to provide power support for air conditioning equipment during peak electricity consumption periods. Its purpose is to ensure that peak shaving operations accurately call upon the designated capacity without encroaching on emergency resources. Emergency capacity refers to the portion of capacity reserved for emergency power supply in the event of grid failure or abnormal operating conditions. It can be achieved by reserving independent capacity blocks or setting thresholds based on the minimum requirements of critical equipment. Its purpose is to ensure that the system has a buffer capability for continuous power supply in the event of sudden interruption. For example, it can maintain full capacity for 15 minutes of emergency discharge capability.

[0044] Air conditioning equipment type refers to the specific model, power rating, or application scenario classification of air conditioners, aiming to distinguish the inherent differences in operating power and energy consumption modes among different air conditioners. Air conditioning capacity analysis refers to assessing the load characteristics of air conditioning equipment during operation, aiming to accurately reflect the actual load demand of the equipment. Based on the analysis and verification of air conditioning load operation data according to different air conditioning types, the energy storage configuration capacity is determined to ensure that the energy storage system can meet the combined power supply demand under the power balance point strategy while avoiding capacity redundancy or insufficiency, thereby achieving efficient allocation of energy storage resources within the target time period and optimizing the utilization of municipal power capacity resource pools.

[0045] In this example implementation, the energy storage battery's capacity structure is divided into two independent functional units: energy storage capacity and emergency capacity. When the operating power exceeds the power balance point, only the energy storage capacity is activated to participate in joint power supply to optimize the utilization of the basic power resource pool, while the access rights for emergency capacity are strictly isolated. When a grid failure occurs, the emergency capacity ensures that critical equipment receives uninterrupted power support, ensuring that it is always maintained above the safety threshold to cope with emergencies. Through the above technical solution, excessive consumption of emergency capacity during joint power supply is effectively prevented, ensuring the data center's emergency response capability during power peak shaving operations, thereby improving the stability and resource utilization efficiency of the power supply system.

[0046] In this example implementation, the sum of the differences between the operating power and the power balance point in each time period within the historical time cycle is the first preset value.

[0047] The sum of differences refers to the cumulative value of the deviations between the operating power and the power balance point in various time periods within a historical time cycle. This can be achieved through mathematical summation, aiming to quantify the overall trend of historical power fluctuations. The first preset value can be determined based on the statistical distribution patterns of historical power data or data center operating experience. Its purpose is to provide quantifiable constraints for generating the power balance point, avoiding the impact of local power anomalies on the balance point setting. In practical applications, the first preset value can be set to 0, or it can be set to other values ​​according to actual needs.

[0048] Figure 6 A schematic diagram of the cooling power fluctuation curve of an air conditioning device in a specific embodiment of the present disclosure is shown. By analyzing the cooling power fluctuation curves for each month, it can be seen that the peak cooling power load generally occurs during the daytime period from June to September. The energy storage battery can participate in the discharge during this period and supply power to part of the peak cooling load through the battery.

[0049] Based on the operating power, a balance point is found. Below the balance point is the off-peak electricity period and battery charging time, while above the balance point is the peak electricity period and battery discharging time, which is supplied in conjunction with the mains power. Experiments show that the energy storage utilization rate is highest when the sum of the differences between the power in each period and the balance point is equal to 0.

[0050] Figure 7 A schematic diagram of the power balance point of an air conditioning device in one specific embodiment of this disclosure is shown. Charging power ≈ discharging power, and the balance point power is 161 kW. When the air conditioning power is below 161 kW, the entire capacity is powered by the mains power supply battery; when the air conditioning power is above 161 kW, the excess capacity is powered by the discharge of the energy storage battery.

[0051] In this example implementation, by setting the sum of the differences between the operating power and the power balance point within a historical time period to a fixed preset value, the determination process of the power balance point comprehensively considers the power distribution characteristics of the entire historical period. Since the sum of the differences is constrained to a first preset value, the power balance point can dynamically adapt to the statistical patterns of historical power, thereby triggering the switching timing between basic power supply and combined power supply more accurately within the target time period. Based on this constraint mechanism, the generation of the power balance point avoids excessive reliance on data from a single time period, ensuring the stability of power supply strategy switching, and thus effectively matching the charging and discharging behavior of the energy storage battery with the power supply capacity of the basic power resource pool.

[0052] In step S320, when the operating power of the air conditioning equipment during the target time period is less than or equal to the power balance point, the air conditioning equipment is supplied with power through the basic power resource pool, and the energy storage battery on the uninterruptible power supply is charged.

[0053] In this example implementation, when the operating power of the air conditioning equipment is less than or equal to the power balance point during the target time period, the air conditioning equipment is directly powered through the basic power resource pool, while the energy storage battery is charged, thereby converting redundant power into dispatchable resources during low-load periods. The basic power resource pool can be, for example, a municipal power resource pool.

[0054] In step S330, when the operating power of the air conditioning equipment is greater than the power balance point within the target time period, the air conditioning equipment is jointly powered by the energy storage battery and the basic power resource pool.

[0055] In this example implementation, when the operating power of the air conditioning equipment is greater than the power balance point within the target time period, the energy storage battery and the basic power resource pool are configured to jointly supply power, sharing the instantaneous load of the municipal power resource pool during high-load periods.

[0056] In this example implementation, a target control program for the energy storage battery can be obtained based on the target geographical location of the air conditioning equipment, the target time period, and the energy storage capacity of the energy storage battery; within the target time period, the energy storage battery is charged and discharged based on the target control program by an uninterruptible power supply.

[0057] The target geographical location refers to the specific geographical area where the air conditioning equipment is installed, and the target control program refers to the set of control instructions for the charging and discharging behavior of the energy storage battery. This can be implemented using a predefined strategy table or a real-time calculated control algorithm, with the aim of achieving precise decision-making regarding charging and discharging timing. The UPS can control the charging and discharging of the energy storage battery, and based on actual time and capacity, a pre-defined control program can be created to achieve automatic control.

[0058] First, the target geographical location, target time period, and energy storage capacity of the air conditioning equipment are obtained. Based on these input parameters, a target control program is generated. This target control program comprehensively considers the climate differences caused by the geographical location, the load variation pattern within the time period, and the physical limitations of the energy storage capacity, thereby formulating an adaptive charging and discharging strategy. Within the target time period, the uninterruptible power supply (UPS) executes charging and discharging control in real time according to the target control program, ensuring that the charging and discharging behavior of the energy storage battery is synchronized with the operating power demand of the air conditioning equipment. This avoids the rigidity of fixed strategies and achieves optimized allocation of power resources.

[0059] In this example implementation, historical temperature data of the target geographical location can be obtained, and the effective time period of the strategy can be determined based on the historical temperature data. If the target time period is within the effective time period of the strategy, a target control program is generated, and the energy storage battery is charged and discharged based on the target control program through an uninterruptible power supply.

[0060] The effective period of the strategy refers to the time period determined based on historical temperature data when the operating power of air conditioning equipment is likely to exceed the power balance point. This can be achieved using analysis methods based on historical temperature peaks or temperature thresholds. The purpose is to accurately identify high-load risk periods and avoid triggering control programs during low-load periods. Depending on the project location, the peak electricity consumption period (such as summer) can be determined, thus determining the activation time of the energy storage peak shaving strategy and automatically entering the energy storage peak shaving control strategy.

[0061] Figure 8A schematic diagram of the annual temperature curve of a specific geographical location in one embodiment of this disclosure is shown. By analyzing historical temperature data of the target geographical location, the effective time period of the strategy is determined. Subsequently, it is determined whether the target time period falls within that time period. Only when it falls within that time period is the target control program generated and the charging and discharging control executed. This mechanism uses temperature data as the basis for decision-making, ensuring that the control program is activated only during periods of high ambient temperature and high air conditioning load, thereby blocking the generation of invalid control commands in low temperature and low load scenarios and achieving precise triggering of charging and discharging operations.

[0062] In this example implementation, such as Figure 9 As shown, the above power supply method may also include the following steps: Step S910. Determine the data balance point of the correlation data within the target time period based on the power resource correlation data of each time period within the historical time period corresponding to the target time period.

[0063] Power resource-related data can include, for example, electricity prices. The equilibrium point for this data can be, for instance, an electricity price threshold calculated based on historical price data. For instance, during non-summer peak air conditioning consumption periods, the air conditioning load is inherently low, eliminating the need for energy storage for peak shaving. During this time, energy storage can be used in conjunction with peak-valley pricing to achieve the goal of saving electricity costs and resources.

[0064] Step S920. When the power resource correlation data within the target time period is less than or equal to the correlation data balance point, power the air conditioning equipment through the basic power resource pool and charge the energy storage battery on the uninterruptible power supply.

[0065] The system monitors electricity prices in real time within the target time period and dynamically compares them with the electricity price equilibrium point. When the real-time electricity price is lower than or equal to the electricity price equilibrium point, it directly supplies power to the air conditioning equipment through the basic power resource pool. At the same time, it converts excess electrical energy into chemical energy and stores it in the energy storage battery, thereby achieving efficient capture of low-priced electrical energy.

[0066] Step S930. When the power resource correlation data within the target time period is greater than the correlation data balance point, the air conditioning equipment is jointly powered by the energy storage battery and the basic power resource pool.

[0067] When the real-time electricity price is higher than the electricity price equilibrium point, the system switches to a collaborative power supply mode between the energy storage battery and the basic power resource pool, calling upon the stored low-priced electricity to share part of the load, thereby reducing dependence on high-priced municipal electricity. This closed-loop control mechanism based on electricity price perception deeply matches the charging and discharging behavior of the energy storage system with the electricity price cycle, forming a complete economic dispatch logic.

[0068] Figure 10A schematic diagram of a multi-power supply architecture in a specific embodiment of this disclosure is shown. The air conditioning units can be integrated refrigerant pump air conditioners. The power distribution architecture of route A consists of one 400KVA UPS supplying power to four integrated refrigerant pump air conditioners, while simultaneously connecting multiple lithium battery cabinets as energy storage batteries. 314Ah (ampere-hours) indicates the battery capacity; 48#pack refers to a standard battery pack consisting of 48 cells connected in series; 4pack refers to a lithium battery cabinet consisting of four such battery packs. The power distribution architecture of route B does not connect to energy storage batteries. HVDC (High Voltage Direct Current) system is a data center power supply technology. Based on this, the route A architecture can achieve joint power supply from energy storage batteries and municipal power resource pools during high-load periods using the above power supply control method, effectively shaving peak loads and optimizing power resource utilization. The above case is based on a single region and a single type of air conditioning unit, demonstrating the feasibility of this solution for different regions and different types of air conditioning units.

[0069] Figure 11 A schematic diagram of IT output rate in a specific embodiment of this disclosure is shown. By using energy storage to reduce peak power, the reduced power can be converted into IT power, thereby increasing IT output rate while keeping the rated power of the mains power unchanged.

[0070] Figure 12 A schematic diagram of charge and discharge related data in a specific embodiment of this disclosure is shown. The maximum power that the mains power needs to provide for the air conditioner is 199.51 kW. Through energy storage and peak shaving, the maximum power that the mains power needs to provide for the air conditioner becomes 161 kW, reducing the power occupied by the air conditioner in the mains power resource pool by 38.51 kW. This portion of the power resources can be used to power IT equipment, improving the output rate of IT resources.

[0071] The power supply control method in this example implementation can be applied to northern regions. Due to the large seasonal and diurnal temperature variations in northern regions, cooling power fluctuates regularly with weather changes: high in summer and low in spring, autumn, and winter; high during the day and low at night. By combining traditional data center backup power architecture and air conditioning operating characteristics with an energy storage system, peak shaving is achieved during peak power load periods using energy storage batteries. This optimizes the municipal power capacity resource pool, releasing more allocable capacity for IT equipment expansion and generating more IT resource output.

[0072] It should be noted that although the steps of the method in this disclosure are described in a specific order in the accompanying drawings, this does not require or imply that the steps must be performed in that specific order, or that all the steps shown must be performed to achieve the desired result. Additional or alternative steps may be omitted, multiple steps may be combined into one step, and / or a step may be broken down into multiple steps.
