[0065] Figure 1 A flowchart of a data center energy efficiency management method based on digital twins is provided for an embodiment of the present application, such as Figure 1 As shown, the method includes:
[0066] 101. Construct a digital twin of a data center, wherein the digital twin includes a digital representation of the physical infrastructure, energy consumption data, environmental parameters, and operating status information of the data center;
[0067] In this step, building a digital twin of a data center means creating a highly accurate virtual model that reflects the actual physical facilities, energy consumption, environmental parameters (such as temperature, humidity, etc.) and real-time operating status of the data center. The digital twin includes not only static data center structure information, but also dynamic operational data, allowing managers to understand the current status of the data center through this virtual model and simulate different operating scenarios to predict future behavior. Building a digital twin usually requires integrating data from different sources, such as sensors, control systems, and other IT infrastructure management systems.
[0068] The following is a brief introduction to the concepts involved:
[0069] Physical Infrastructure: refers to all hardware facilities in the data center, such as servers, routers, switches, cooling systems, power supply equipment, etc.
[0070] Energy Consumption Data: refers to the actual power consumption of each device in the data center, including but not limited to the power consumption of servers and air conditioning systems.
[0071] Environmental Parameters: including temperature, humidity, air quality and other indicators. These parameters directly affect the operating efficiency and equipment life of the data center.
[0072] Operational State Information: refers to the working status of equipment in the data center, such as server load, network traffic, fault alarms, etc.
[0073] In the embodiment of this application, it is assumed that a digital twin of a data center is being constructed. The data center includes multiple racks, each of which is equipped with multiple servers and is equipped with a precision air conditioning system and an uninterruptible power supply system. The following is a specific example of the construction process:
[0074] Physical infrastructure modeling: Collect information about all hardware devices in the data center, including model, location, connection relationship, etc., and create corresponding digital models in a virtual environment.
[0075] Energy consumption data collection: Deploy sensors and monitoring software to monitor the energy consumption of each device in the data center in real time, and map this data to the energy consumption attributes of the corresponding equipment in the digital twin.
[0076] Environmental parameter monitoring: Install environmental monitoring equipment such as temperature and humidity sensors to obtain real-time environmental parameters inside the data center and input these data into the corresponding modules of the digital twin.
[0077] Integration of operation status information: Integrate the monitoring system in the data center to collect operation status information such as server load and network traffic, and reflect it in the digital twin.
[0078] In an embodiment of the present application, a digital twin of a data center is constructed, which includes a server room, a cooling system, a power supply system, etc. First, the location, specifications, connection methods and other information of all key equipment are entered into the digital twin platform to form a three-dimensional layout diagram of the data center. Secondly, various sensors are installed to monitor key parameters such as temperature, humidity, and power consumption in real time, and these data are transmitted to the digital twin in real time. Furthermore, the existing data center infrastructure management system (DCIM) and building automation system (BA) are integrated to ensure that the digital twin can access the status and energy consumption data of the relevant equipment. Finally, historical data is imported into the digital twin, and these data are used to calibrate the model so that it can more accurately reflect the operation of the actual data center.
[0079] The effect of this step is that data center managers can remotely monitor the status of the data center and evaluate the impact of different strategies through simulation tests, so as to make more informed decisions. The purpose is to improve the operational efficiency and reliability of the data center by integrating various data sources and utilizing advanced simulation technology. The design principle is to combine IoT technology, cloud computing and big data analysis capabilities to build a virtual mirror that can reflect the real-world data center. Compared with traditional solutions, digital twins provide a more dynamic and interactive way to manage and optimize data centers, reducing the delays and misjudgment risks caused by relying on manual inspections, and also laying the foundation for future intelligent operations.
[0080] 102. Synchronize the actual operating status of the data center to the digital twin in real time to ensure that the digital twin can dynamically reflect the current operating status of the data center;
[0081] Optionally, the real-time synchronization of the actual operating status of the data center to the digital twin in step 102 to ensure that the digital twin can dynamically reflect the current operating status of the data center, including: real-time collection of the physical infrastructure, energy consumption data, environmental parameters and operating status information of the data center through different sensors deployed in the data center; using data fusion technology to integrate data streams from different sensors to form a unified data view; and transmitting the unified data view to the digital twin in real time to ensure that the digital twin can dynamically reflect the current operating status of the data center.
[0082] In this step, we will introduce in detail how to collect key data of the data center in real time through sensors deployed in the data center, and integrate this data using data fusion technology to ensure that the digital twin can dynamically reflect the current operating status of the data center:
[0083] Sensors: used to monitor various physical quantities in the data center in real time, such as temperature sensors, humidity sensors, current sensors, etc.
[0084] Data Fusion Technology: refers to a method of obtaining information from multiple data sources and combining the information to infer or estimate the optimal state of an event.
[0085] Unified Data View: refers to integrating data from different sensors into a whole to better understand and analyze the status of the data center.
[0086] Real-Time Transmission: refers to the transmission process of data from the collection point to the processing platform with no delay or very short delay.
[0087] In the embodiment of the present application, various types of sensors are first deployed in the data center, for example:
[0088] The temperature sensor is used to measure the temperature distribution in the equipment room.
[0089] Humidity Sensor is used to monitor air humidity.
[0090] Current transformers are used to detect the current consumption of servers and other equipment.
[0091] The voltage sensor is used to detect the voltage level of the power supply line.
[0092] Network Traffic Monitor is used to monitor the data transmission of network devices.
[0093] Furthermore, data fusion technology is used to integrate data streams from different sensors. For example, the data from all sensors can be received through the Central Control System, and algorithms can be used to eliminate redundant information, fill in missing data, etc. to form a unified data view. Real-time transmission to the digital twin: The processed unified data view is transmitted to the digital twin of the data center in real time through a high-speed network connection to ensure that the digital twin can instantly reflect the current operating status of the data center.
[0094] Effect, purpose and design principle of this step:
[0095] The core purpose of this step is to ensure that the digital twin is consistent with the actual data center, so that any operation and simulation on the twin can be based on the latest actual data. Compared with traditional manual inspection or scheduled data upload, real-time synchronization provides higher reliability and accuracy, and can detect and respond to problems faster.
[0096] By synchronizing data in real time, digital twins can more effectively support energy efficiency management and optimization decisions. For example, when an abnormally high temperature in a certain area is detected, the cooling system’s operating mode can be adjusted to respond quickly to avoid equipment failures caused by overheating.
[0097] Assume that in a data center, there are the following sensors deployed:
[0098] The 10 temperature sensors are distributed in different cabinets.
[0099] There are 5 humidity sensors located on different floors.
[0100] 20 current transformers are connected to servers and other key equipment.
[0101] 1 network traffic monitor is connected to the core switch.
[0102] When these sensors start working, they send data to the central control system every few seconds. The central control system uses data fusion algorithms to organize this data and send the organized information to the digital twin. For example, if the temperature suddenly rises somewhere, the central control system will immediately transmit this information to the digital twin along with the associated humidity, current consumption and other data, so that managers can immediately see the problem and take corresponding measures.
[0103] 103. Based on the digital twin, simulate the impact of different energy efficiency optimization strategies on the energy efficiency of the data center, wherein the energy efficiency optimization strategies include adjusting the working mode of the cooling system, adjusting the load distribution of the physical infrastructure, and optimizing the energy supply strategy;
[0104] Optionally, the digital twin-based simulation in step 103 simulates the impact of different energy efficiency optimization strategies on the energy efficiency of the data center, and the energy efficiency optimization strategy includes adjusting the working mode of the cooling system, adjusting the load distribution of the physical infrastructure, and optimizing the energy supply strategy, including: setting the working mode parameter set of the cooling system through the data analysis module integrated in the digital twin, and the parameter set at least includes the start / stop time, operating frequency and temperature of the cooling medium of the cooling equipment; in the digital twin, simulating the impact of the working mode parameter set of the cooling system on the internal temperature distribution and energy consumption of the data center to obtain a first simulation result; adjusting the physical infrastructure according to the load distribution of IT equipment through the resource scheduling module in the digital twin. The load distribution of the implementation is implemented, and the adjustment at least includes adjusting the power supply and cooling resources to better match the current IT load demand; on the digital twin, the impact of the physical infrastructure load distribution on the overall energy efficiency and equipment performance of the data center is simulated to obtain a second simulation result; through the energy management module in the digital twin, the energy supply strategy is optimized, and the optimization at least includes adjusting the power supply time using the peak and valley electricity price strategy, introducing the proportion of renewable energy use, and adjusting the switching logic of the backup power supply; on the digital twin, the impact of the optimized energy supply strategy on the energy consumption and cost of the data center is simulated to obtain a third simulation result; and multiple simulation results under different energy efficiency optimization strategies are compared to determine the optimal energy efficiency optimization strategy combination.
[0105] In this step, different energy efficiency optimization strategies will be simulated based on the digital twin, and their impact on the energy efficiency of the data center will be evaluated. Specifically, the working mode of the cooling system will be adjusted, the load distribution of the physical infrastructure will be adjusted, and the energy supply strategy will be optimized:
[0106] Data Analysis Module: used to process and analyze various data integrated in the digital twin to support decision-making.
[0107] Cooling System Operation Parameters Set: includes the start / stop time, operating frequency and temperature of the cooling medium of the cooling equipment.
[0108] Resource Scheduling Module: Responsible for managing the load distribution of the physical infrastructure within the data center to ensure efficient use of resources.
[0109] Energy Management Module: used to optimize energy supply strategies, including adjusting power supply time and introducing renewable energy.
[0110] In the embodiment of the present application, the working mode parameter set of the cooling system is set:
[0111] The start / stop time, operating frequency, and temperature of the cooling medium of the cooling equipment are set in the data analysis module of the digital twin.
[0112] For example, cooling equipment can be set to run less frequently during off-peak hours and the temperature of the cooling water can be adjusted to reduce energy consumption.
[0113] The impact of the working mode parameter set of the simulated cooling system on the temperature distribution and energy consumption inside the data center:
[0114] The digital twin is used to simulate the impact of changes in the above settings on the temperature distribution inside the data center.
[0115] For example, it simulates the impact of reducing the frequency of cooling equipment operation during a specific period of time on the temperature rise inside the data center and the resulting changes in energy consumption.
[0116] Redistribute the load on the physical infrastructure:
[0117] The resource scheduling module in the digital twin is used to redistribute the load of the physical infrastructure.
[0118] Simulate the impact of load distribution of physical infrastructure on the overall energy efficiency and equipment performance of the data center:
[0119] The impact of the above load redistribution strategy on the overall energy efficiency and equipment performance of the data center is simulated in the digital twin.
[0120] For example, the total energy consumption changes of the data center and the performance changes of the server after simulating load balancing.
[0121] Optimizing energy supply strategies:
[0122] Use the energy management module in the digital twin to optimize the energy supply strategy, such as using peak and valley electricity price strategies to adjust the power supply time, introduce the proportion of renewable energy such as solar energy, and adjust the switching logic of backup power supplies.
[0123] For example, you could set it up to use more electricity during times when electricity prices are lower, and consider using solar power to supplement grid power during the day.
[0124] Simulate the impact of optimized energy supply strategy on data center energy consumption and cost:
[0125] The impact of the above optimized energy supply strategy on the energy consumption and cost of the data center is simulated in the digital twin.
[0126] For example, simulating the impact of using solar power generation during the day on the total energy consumption and operating costs of a data center.
[0127] Compare multiple simulation results under different energy efficiency optimization strategies:
[0128] Compare the above simulation results to find the best energy efficiency optimization strategy combination in different dimensions (such as energy consumption reduction, cost savings, etc.).
[0129] Effect, purpose and design principle of this step:
[0130] The main purpose of this step is to find the best strategy combination under various conditions by simulating different energy efficiency optimization strategies. Compared with the traditional trial and error method, this method can find the best solution through multiple attempts in a virtual environment without interfering with the actual data center operation. This can not only improve the energy efficiency of the data center, but also significantly reduce operating costs.
[0131] Suppose there are several strategies that need to be simulated:
[0132] Strategy A: Increase the operating frequency of cooling equipment at night (when electricity prices are low) and adjust the cooling water temperature to a lower level.
[0133] Strategy B: Rational deployment of redundant infrastructure to achieve reasonable distribution of energy and cooling loads.
[0134] Strategy C: Use solar power during the day and increase grid power when electricity prices are low.
[0135] The simulation results show:
[0136] Strategy A: After increasing the frequency of cooling equipment operation at night, the temperature inside the data center rose slightly during the day, but the overall energy consumption was reduced by 10%.
[0137] Strategy B: After redistributing the load, the overall server utilization rate increased by 15% and the energy consumption decreased by 5%.
[0138] Strategy C: After using solar power, daytime energy consumption was reduced by 8% and operating costs were reduced by 12%.
[0139] On the whole, the strategy combination A+B+C performed best in terms of energy consumption reduction and cost savings, and was therefore identified as the optimal energy efficiency optimization strategy combination.
[0140] 104. Selecting an energy efficiency optimization strategy with the best evaluation result on the digital twin, and applying the best energy efficiency strategy to the energy efficiency management of the data center to improve the energy efficiency of the data center and reduce operating costs;
[0141] Optionally, the selection of the energy efficiency optimization strategy with the best evaluation result on the digital twin in step 104, and applying the optimal energy efficiency strategy to the energy efficiency management of the data center, includes: defining an evaluation index system based on multiple simulation results in the digital twin, the evaluation index system at least including energy consumption reduction rate, equipment service life impact, operating cost savings and strategy implementation feasibility; using the evaluation index system to comprehensively evaluate all energy efficiency optimization strategies simulated on the digital twin to obtain a comprehensive evaluation result; based on the comprehensive evaluation result, selecting the energy efficiency optimization strategy with the highest score as the optimal strategy; converting the optimal strategy into specific execution instructions, the execution instructions include but are not limited to adjusting the control parameters of the cooling system, reallocating the load of the physical infrastructure, and optimizing the energy supply; applying the execution instructions to the actual operation of the data center through an automated control system or manual intervention to implement the optimal energy efficiency optimization strategy.
[0142] In this step, an evaluation index system is defined based on multiple simulation results in the digital twin, and this system is used to comprehensively evaluate all simulated energy efficiency optimization strategies, and finally the strategy with the highest score is selected as the optimal strategy. In addition, the optimal strategy is converted into specific execution instructions and applied to the operation of the actual data center:
[0143] Evaluation Indicator System: A set of standards used to evaluate the effectiveness of energy efficiency optimization strategies, including energy consumption reduction rate, impact on equipment lifespan, operational cost savings, and feasibility of implementation.
[0144] Comprehensive Evaluation Result: A comprehensive evaluation score or ranking obtained by quantitatively comparing the performance of all energy efficiency optimization strategies in the evaluation index system.
[0145] Execution Commands: Convert the selected optimal strategy into actual operational commands, such as adjusting the control parameters of the cooling system, redistributing the load of the physical infrastructure, and optimizing the way energy is supplied.
[0146] Automation Control System or Manual Intervention: Instructions are automatically executed by the automation control system, or the administrator manually adjusts the equipment configuration according to the instructions to implement energy efficiency optimization strategies.
[0147] In the present application embodiment:
[0148] Define the evaluation indicator system:
[0149] Energy consumption reduction rate: The percentage of energy consumption reduction brought about by the energy efficiency optimization strategy in the simulation results.
[0150] Impact on equipment life: The impact of the evaluation strategy on the long-term operating stability of the equipment.
[0151] Operational cost savings: Calculate the amount of cost savings after implementing the strategy.
[0152] Feasibility of strategy implementation: Consider whether the strategy is easy to implement and its impact on daily operations.
[0153] Comprehensive evaluation using the evaluation indicator system:
[0154] Assuming there are three energy efficiency optimization strategies (A, B, C), the evaluation results are as follows:
[0155] Strategy A: Energy consumption is reduced by 10%, the impact on equipment service life is small, operating cost savings are 50,000 yuan, and implementation feasibility is high.
[0156] Strategy B: Energy consumption reduction rate is 12%, which has a significant impact on the service life of equipment, and the operating cost savings is RMB 30,000. The feasibility of implementation is average.
[0157] Strategy C: Energy consumption reduction rate is 8%, the impact on equipment service life is small, operating cost savings are RMB 40,000, and implementation feasibility is high.
[0158] Select the energy efficiency optimization strategy with the highest score:
[0159] Taking all indicators into consideration, Strategy C performs well in terms of energy consumption reduction rate, operating cost savings and implementation feasibility. Although its energy consumption reduction rate is not as good as Strategy B, Strategy C is selected as the optimal strategy because of its small impact on equipment service life and strong implementation feasibility.
[0160] Convert the optimal strategy into specific execution instructions:
[0161] Specific instructions for strategy C may include adjusting the operating frequency of the cooling system, reallocating some computing tasks to low-load servers, and adjusting the power supply schedule.
[0162] Implement optimal strategies through automated control systems or human intervention:

[0164] Effect, purpose and design principle of this step:
[0165] The purpose of this step is to ensure that the selected energy efficiency optimization strategy can not only improve energy efficiency in the short term, but also ensure the normal operation of the equipment in the long term, while taking into account the feasibility and cost-effectiveness of the strategy implementation. Compared with traditional solutions, this method selects the optimal strategy by comprehensively evaluating the performance of multiple dimensions, rather than deciding based on the effect of a single aspect, so it is more scientific and reasonable.
[0166] Assume that after comprehensive evaluation, strategy C is finally selected as the optimal strategy. The following are the specific implementation steps:
[0167] Adjust the operating frequency of the cooling system:
[0168] Reduce the operating frequency of the cooling system from 80% to 70% and further reduce it to 60% during off-peak hours.
[0169] Redistribute computing tasks:
[0170] Transfer some computing tasks from servers with higher load to servers with lower load to balance the load among servers.
[0171] Adjustment of electricity supply schedule:
[0172] Increase electricity supply during the night time when electricity prices are lower, and reduce electricity consumption during the day time when electricity prices are higher.
[0173] Through the above adjustments, it is expected that the energy consumption of the data center will be reduced by about 8%, and the operating costs will be reduced by about 40,000 yuan. At the same time, the service life of the equipment will be less affected and the feasibility of implementation will be higher. These measures will help improve the energy efficiency of the data center and reduce operating costs.
