[0095] Example 1

[0096] Please refer to Figure 1 The following is a flowchart illustrating a method for optimizing the operation of a power distribution network considering a data center, as provided in an embodiment of the present invention, comprising the following specific steps:

[0097] S1. Based on the constituent equipment of the data center, construct a total power consumption model for the data center equipment; wherein, the constituent equipment includes: servers, air conditioning equipment, and auxiliary equipment;

[0098] Preferably, the step of constructing the total power consumption model of the data center based on the constituent equipment of the data center includes: constructing a server power consumption model for a single server in the data center, and obtaining the number of servers that are powered on in the data center, and then obtaining the total power consumption model of the servers that are powered on in the data center based on the server power consumption model and the number of servers that are powered on; obtaining the cooling power and energy efficiency coefficient of the air conditioning equipment in the data center, and then constructing an air conditioning power consumption model of the air conditioning equipment in the data center based on the cooling power and energy efficiency coefficient; obtaining the power consumption coefficient of the data center, and then constructing the total power consumption model of the data center based on the power consumption coefficient, the total power consumption model of the servers, and the air conditioning power consumption model.

[0099] Preferably, the total power consumption model of the device is as follows:

[0100]

[0101]

[0102]

[0103] in, Let t be the total energy consumption of data center i at time t; The energy consumption of server equipment in data center i at time t; η is the energy consumption of the cooling equipment in data center i at time t. DC The power consumption factor for the data center; u i,t This refers to the server's CPU utilization. This refers to the number of servers that are currently running. Let η be the cooling power of the air conditioning unit in data center i at time t; ACS The energy efficiency coefficient of air conditioning equipment.

[0104] Specifically, this invention aims at low-carbon economic operation, considering the efficient integration and coordinated operation of DC and distribution networks, and proposes a low-carbon economic operation framework for an active distribution network that takes into account the spatiotemporal flexibility of data centers. Unlike existing technologies, this invention aims to explore the spatiotemporal flexibility of data centers and investigate the potential value of DC flexibility in promoting low-carbon and economic efficiency improvements in distribution systems. By comprehensively considering constraints such as DC energy consumption and flexibility adjustments, a data center energy consumption and spatiotemporal flexibility model is established. Based on this, the balance between low-carbon and economic operation of data centers is coordinated, and an optimization model for low-carbon operation of an active distribution network that takes into account the spatiotemporal flexibility of data centers is constructed. Through joint optimization of source, network, and load resources, a synergistic optimization of the overall system's economic and low-carbon benefits is achieved. The specific implementation is as follows:

[0105] 1. Optimized operation framework for power distribution networks including data centers:

[0106] Please refer to Figure 2 This is a diagram illustrating the optimized operation architecture of an active distribution network including a data center. The DC power distribution system mainly consists of three parts: distribution network lines, data center network, and distributed power sources. The electrical equipment within the DC mainly includes IT equipment, represented by servers and virtual machines (VMs), as well as other auxiliary equipment such as cooling and lighting.

[0107] Data centers can adjust their energy consumption characteristics by leveraging the adjustability of their data resources, thus exhibiting excellent flexibility. Therefore, data centers can participate in the interactive operation of the distribution network through this flexibility. On one hand, by flexibly adjusting their data resources and coordinating with the distribution network, data centers can promote the absorption of distributed renewable energy within the distribution network and reduce its operating costs. On the other hand, by fully absorbing and utilizing distributed renewable energy in the distribution network, they can reduce electricity purchases from the main grid, achieving low-carbon operation of the distribution network.

[0108] Based on the operational characteristics of data centers and distribution networks, distribution network operators aim to simultaneously reduce overall system operating costs and improve system economics, while also maximizing the utilization of distributed energy resources within the distribution network area to promote carbon emission reduction in the power system. Therefore, decision-making requires balancing both economic and low-carbon optimization objectives.

[0109] Based on the above analysis, the power distribution network operation optimization problem involving data centers is constructed into an optimization model, such as... Figure 2As shown, this model considers both operating costs and carbon emission costs. Objective 1 aims to minimize system operating costs, while objective 2 aims to minimize system carbon emission costs. By optimizing the operating strategies of DC (including information load migration, server start / stop status, and cooling equipment output) and distribution network (including RES output and mains power purchase) at different time periods, a low-carbon and economical operation of the distribution network that takes into account the spatiotemporal flexibility of data centers is achieved.

[0110] 2. Data center energy consumption and spatiotemporal flexibility modeling:

[0111] To fully understand the energy consumption characteristics and spatiotemporal flexibility of data centers, the following model is used to model these characteristics:

[0112] 2.1 Data Center Energy Consumption Characteristics Modeling:

[0113] The power consumption of a DC mainly consists of three parts: servers, air conditioning equipment, and other auxiliary equipment. The power consumption of servers and air conditioning equipment usually accounts for more than 90% of the total power consumption of a DC

[11] . Therefore, when modeling the total power consumption of its equipment, it can be expressed by the following formula:

[0114]

[0115] In the formula, This represents the total energy consumption of data center i at time t; This represents the energy consumption of server i in the corresponding data center at time t. This represents the energy consumption of the cooling equipment in data center i at time t. This represents the energy consumption of other auxiliary equipment in the corresponding data center at time t.

[0116] Because there are many other auxiliary devices and their energy consumption is relatively small, the energy consumption factor of the data center is often used for energy consumption modeling, as shown in the following formula:

[0117]

[0118] In the formula, η DC The power consumption factor represents the power consumption of a data center, which is the ratio of the sum of the power consumption of servers and air conditioning equipment to the total power consumption of the data center.

[0119] The power consumption of a server is generally proportional to the CPU utilization. Let Pmin be the power of the CPU when its utilization is 0%, i.e., its silent power when not processing network tasks, and Pmax be the power of the CPU when its utilization is 100%, i.e., its peak power under full load. Based on this, the power consumption of a single server in a DC system at time t can be calculated as follows:

[0120]

[0121] In the formula, u i,t This refers to the server's CPU utilization.

[0122] When modeling the total power consumption of a data center, considering the linear relationship between server power consumption and the number of servers in operation at real time, the power consumption of all servers in the data center can be defined as a linear mathematical model. Therefore, the total power of the servers in the data center at time t is:

[0123]

[0124] In the formula, This represents the number of servers that are currently running.

[0125] To ensure the ambient temperature meets the operating requirements of servers and other equipment, a large number of air conditioning and refrigeration units are required within the DC (Distributed Control Center). The air conditioning and refrigeration system converts electrical energy into low-temperature internal energy through a compressor, and its operating characteristics are as follows:

[0126]

[0127] In the formula, η represents the cooling power of the air conditioning unit in data center i at time t; ACS The coefficient of performance (COP) represents the energy efficiency ratio of an air conditioning unit, which is the ratio of the cooling capacity to the electrical power consumed by the unit.

[0128] S2. Based on the data load types of the data center, construct data load models for each type of data load, and then construct the overall data load model of the data center based on the data load models for each type of data load; wherein, the data load types include: time-transferable data load, time-reducible data load, spatially transferable data load, and rigid data load.

[0129] Preferably, the data load model is:

[0130]

[0131]

[0132]

[0133]

[0134]

[0135]

[0136]

[0137]

[0138] Among them, TSDL stands for Time-Transferable Data Load; TRDL stands for Time-Reducible Data Load; STDL stands for Spatially Transferable Data Load; and RDL stands for Rigid Load. This represents the capacity percentage of TSDL. The amount of data load that can be transferred after the task migration; The initial total data load received by the DC; β TSDL This represents the percentage of TSDL in the total data tasks. This is the initial value for TSDL; This refers to the amount of data load transferred from time t' to time t; The data load transferred from time t to time t'; β represents the TSDL data load in the data center at time t. TRDL To reduce the proportion of data load; The initial data load can be reduced at time t; This represents the actual amount of data load reduced. β represents the percentage of STDL capacity; β represents the STDL data load after task migration; β represents the percentage of STDL capacity. STDL This represents the percentage of STDL in the total data tasks. This represents the amount of STDL data before scheduling. This represents the amount of data migrated between data centers i and i'. Let be the RDL capacity at time t.

[0139] 2.2 Data Center Spatiotemporal Flexibility Modeling Based on Data Load:

[0140] The demand responsiveness of a data center (DC) primarily stems from its flexibility in data load scheduling and the spatial transferability of information tasks between DCs in different geographical locations. Based on response methods, data loads in a DC can be broadly categorized into four types for modeling: Time-Shiftable Data Load (TSDL), Time-Reducable Data Load (TRDL), Spatially Transferable Data Load (STDL), and Rigid Data Load (RDL). The characteristics of each type of load will be modeled below:

[0141] Time-transferable data workloads (TSDL) refer to data workloads with a fixed amount of data but flexible processing time within a certain time frame. Data distribution centers (DCs) can postpone the processing time of TSDL tasks to a certain extent within the scheduling cycle based on relevant needs; that is, TSDL demands generated at time t can be postponed to the time period [t+1, T] for processing. This can be modeled as follows:

[0142]

[0143]

[0144] Formula (6) represents the capacity proportion of TSDL, and Formula (7) represents the time-transferable data load after considering TSDL. Wherein, The initial total data load received by the DC; β TSDL This represents the percentage of TSDL in the total data tasks. This is the initial value for TSDL; This refers to the amount of data load transferred from time t' to time t; The data load transferred from time t to time t'; The data load of the data center at time t is the TSDL data load.

[0145] DC can reduce data load TRDL to a certain extent by directly reducing time based on relevant needs within the scheduling cycle. Based on the above description of TRDL, it can be modeled as follows:

[0146]

[0147]

[0148] Where: β TRDL To reduce the proportion of data load; The initial data load can be reduced at time t; This represents the actual amount of data load reduced.

[0149] Spatially portable data workloads (STDL) refer to data workloads with fixed request processing times but capable of flexibly migrating between different geographic data centers (DCs) as needed. Based on the above description of spatially portable data workloads (TRDL), they can be modeled as follows:

[0150]

[0151]

[0196] 3. Optimization model for low-carbon operation of active distribution networks considering the spatiotemporal flexibility of data centers:

[0197] 3.1 Objective Function:

[0198] In this invention, two objectives are considered: economic operation and low-carbon operation of the power distribution network. At the economic operation level, the objective function is constructed to minimize the annual operating cost of the power distribution system, as follows:

[0199]

[0200] System operating cost C O This mainly includes the cost of purchasing electricity from the upper-level power grid and the related costs resulting from DC flexible response:

[0201]

[0202] In the formula, c represents the power purchased from the main grid at time t; Grid Indicates the electricity purchase price in the distribution network; c DR This represents the unit compensation price for data load delays or reductions; p s Ω represents the probability of scenario s occurring; θ represents the number of days; T A collection of moments in a day.

[0203] At the low-carbon operation level, leveraging the operational flexibility of DC (Distributed Generator) can improve power flow distribution in the distribution network, reduce network losses, and promote the absorption and utilization of distributed renewable energy, thereby reducing generation-side emissions and bringing considerable low-carbon benefits. Here, it is assumed that the upstream power grid purchases electricity from conventional coal-fired units, and the carbon cost of system operation is characterized by the generation-side carbon cost incurred by the system in purchasing electricity from the upstream grid.

[0204]

[0205] In the formula, e THG This indicates the carbon emissions per unit output of conventional generating units in the upstream power grid; c e ζ represents the unit carbon emission cost, and ζ represents the proportion of electricity purchased from the main grid for generating electricity for conventional coal-fired units.

[0206] To comprehensively consider the balance between the two objectives, a weighting system is established to represent the weight differences between the different objectives, and the overall objective function is established as follows:

[0207]

[0208] As can be seen from the above equation, the objective function is determined by the system's economic operating cost C. O and carbon emission costs It is a weighted sum of two aspects.

[0209] 3.2 Constraints:

[0210] Regarding constraints, the main considerations include power distribution system operation constraints, distributed power generation output constraints, and data center flexibility constraints. Specifically:

[0211] (1) The power generation of distributed generation in the distribution network system at any given time is constrained by its installed capacity and predicted output.

[0212]

[0213] (2) System operation constraints:

[0214] Node power balancing:

[0215]

[0216]

[0217] Node voltage constraints:

[0218]

[0219] Power flow constraints:

[0220]

[0221] Line current carrying capacity constraints:

[0222]

[0223] Power purchase capacity constraints:

[0224]

[0225] (3) Demand-side constraints:

[0226] To reduce the complexity of problem solving, this paper assumes that all DC servers are of the same model and that during the operation phase, tasks are distributed evenly to each active server. Based on this, according to the M / M / 1 queuing theory

[13] , the data load corresponding to each server can be determined as follows:

[0227]

[0228]

[0229]

[0230] To ensure service requests for system user data load, the DC also needs to strictly meet data load constraints during operation. Constraints are imposed on Time Transferable Data Load (TSDL), Time Reduceable Data Load (TRDL), and Spatially Transferable Data Load (STDL), mainly considering the capacity limitations of each type of data load.

[0231] For Time Transferable Data Loading (TSDL):

[0232]

[0233]

[0234] In the formula, This is the initial value for the data center TSDL; The data load in data center i that is transferred from time t' to time t; The data load of data center i transferred from time t to time t”; Let t represent the amount of TSDL data at time i in data center t.

[0235] TRDL for time-reducing data load:

[0236]

[0237] In the formula: The initial data load of data center i can be reduced at time t; This represents the actual amount of data load reduced.

[0238] For spatially portable data workloads (STDL), considering that the migration volume of STDL must meet the virtual machine capacity limit:

[0239]

[0240]

[0241]

[0242] In the formula, This represents the amount of STDL data before scheduling. The amount of data migrated between data centers i and i' This indicates the virtual machine's transmission capacity per unit of data.

[0243] The air conditioning and refrigeration equipment in the DC unit also needs to operate at its rated power:

[0244]

[0245] In the formula, This refers to the upper limit of the rated power of air conditioning and refrigeration equipment.

[0246] S4. Under the constraints of the above constraints, solve the objective function to obtain the main grid power purchase, transferable load adjustment, relocatable load adjustment and load reduction adjustment of the data center in each time period when the system operating cost and carbon emission cost of the power distribution system are minimized.

[0247] Then, under the constraints, the objective function is solved, and the final solution is obtained when the system operating cost and system carbon emission cost of the power distribution system are minimized, the power purchased from the main grid in each time period, and the load transfer, load migration, and load reduction adjustment amount of the data center in each time period.

[0248] S5. Based on the main grid power purchase capacity of the power distribution system in each time period, the transferable load adjustment amount of the data center in each time period, the relocatable load adjustment amount of the data center in each time period, and the load reduction adjustment amount of the data center in each time period, generate an operation optimization scheme for the power distribution network, and then optimize the operation of the power distribution network according to the operation optimization scheme.

[0249] Finally, based on the main grid power purchase capacity of the power distribution system at each time period, the transferable load adjustment amount of the data center at each time period, the relocatable load adjustment amount of the data center at each time period, and the load reduction adjustment amount of the data center at each time period, an operation optimization scheme for the power distribution network is generated, and then the operation of the power distribution network is optimized according to the operation optimization scheme.

[0250] In a specific embodiment, to verify the effectiveness of the above-mentioned distribution network operation optimization method considering data centers, a simulation analysis is performed using a modified IEEE-33 node distribution network as an example. Please refer to... Figure 3 This is a modified IEEE-33 power distribution system architecture diagram. The system contains 32 branches and 33 load nodes, with a rated voltage of 12.66kV. The data center access nodes in the distribution network are nodes 13, 19, 25, and 26, and the distributed photovoltaic access nodes are nodes 13, 19, 23, and 26. The system contains four types of loads: commercial, industrial, residential, and data center. To reveal the benefits of low-carbon collaborative operation between the DC and distribution networks, the optimal operating results obtained in the following three scenarios are compared and analyzed. The relevant results are shown in Table 1.

[0251] Scenario I: Without considering the spatiotemporal flexibility of the data center, i.e., the data center and distribution network operate independently. This scenario reflects the cost-effectiveness of optimizing the distribution network operation without taking into account the spatiotemporal flexibility of the data center.

[0252] Scenario II: Low-carbon optimization operation of the power distribution network considering the spatiotemporal flexibility of data centers, i.e., only considering the data center TSDL's participation in scheduling and control. This scenario reflects the cost-effectiveness of the system when only partial data center flexibility is considered in operational decisions;

[0253] Scenario III: The model presented in this paper considers the low-carbon optimized operation of the power distribution network, taking into account the full spatiotemporal flexibility of the data center. In this scenario, the DC can schedule TSDL, TRDL, and STDL separately, meaning that all types of flexible resources in the data center can participate in demand response simultaneously.

[0254]

[0255] Table 1 Cost Situation in Different Scenarios

[0256] As shown in Table 1, the distribution network operating costs from Scenario I to Scenario III exhibit a gradually decreasing trend, with Scenario III's total annual operating cost decreasing by 11.49% compared to Scenario I. This is mainly because Scenario III considers various data loads of the DC to participate in demand response, reducing the distribution network's reliance on the main grid for electricity purchases, thus leading to a corresponding reduction in system carbon emissions and electricity purchase costs. The differences between the various scenarios are analyzed below:

[0257] Compared to Scenario I, Scenario II reduces annual electricity purchase costs and carbon emission costs. Compared to Scenario I, Scenario II considers partial demand response in the DC power grid, specifically the demand response of Time Transferable Data Load (TSDL) for 30% of the data center load. This adjustment improves the absorption of distributed photovoltaic power in the system and reduces system operating costs. The fundamental reason is that by adjusting the processing time of the DC data load, the DC power load is adjusted, changing the timing of electricity demand. TSDL-based demand response improves the matching degree between renewable energy generation output and end-user load demand, promoting the utilization of renewable energy and reducing the purchase of electricity from the upper-level grid during peak hours, thus giving the system better operational economy and low-carbon benefits.

[0258] Comparing Scenario III and Scenario II, Scenario III further enhances the spatiotemporal flexibility of DC (Distributed Power Generation) based on Scenario II. It further considers 10% of the time-based data load reduction (TRDL) and 30% of the spatially transferable data load (STDL), making DC more flexible. It can be seen that after comprehensively utilizing the demand response capabilities of DC resources in both time and space dimensions, although the demand response cost increases by 155,800 yuan, the reduction in electricity purchase cost and carbon emission cost brought about by demand response is more significant, reaching 1,370,600 yuan. The system operation can utilize more distributed photovoltaic power, further reducing electricity purchase cost and carbon emission cost. Therefore, investing more adjustable and flexible resources in DC demand response can reduce the operating cost of the distribution network and effectively improve the economic and environmental benefits of the distribution system.

[0259] Please refer to Figure 4 This involves generating photovoltaic (PV) output curves for various scenarios, and analyzing and comparing the distributed PV output and DC operation under different scenarios. Based on... Figure 4It can be seen that, between 12:00 and 16:00, the distributed photovoltaic (PV) grid connection performance is better in Scenario III compared to Scenario I and Scenario II. During peak PV output periods, more distributed PV can be grid-connected through spatiotemporal adjustments to the data load of more data centers. At other times, distributed PV can achieve full grid connection. This is because PV output is mainly concentrated during the daytime, which is also the period of most concentrated load. Therefore, PV output can be effectively matched with load characteristics, achieving efficient PV grid connection.

[0260] Please refer to Figure 5 This is a DC power load curve diagram for various scenarios, based on... Figure 5 It can be seen that in Scenario III, the number of units started and the total power output increased significantly from 0:00 to 6:00 and from 18:00 to 24:00, while the output decreased relatively evenly from 8:00 to 18:00. This adjustment can promote the balance between power grid supply and demand and reduce the power grid's electricity purchase cost, thus further improving its economic benefits.

[0261] Therefore, this invention provides a method for optimizing power distribution network operation considering data centers. Compared with existing technologies, this invention focuses on exploring the role of DC flexibility in improving the economic efficiency and low-carbon benefits of power distribution system operation, based on the data adjustment characteristics of data center demand response. Based on the simulation results of the above examples, the following main conclusions are drawn:

[0262] (1) Compared with the optimized operation of the distribution network that does not consider the spatiotemporal flexibility of the data center, the optimized operation method proposed in this invention can effectively improve the operating efficiency of the distribution network with DC and play an important role in promoting the utilization of renewable energy and carbon emission reduction.

[0263] (2) The expected benefits of optimized operation of distribution network are affected by the spatiotemporal mobility of DC data load. That is, the stronger the spatiotemporal adjustment flexibility of data load of data center, the more significant the economic and low-carbon benefits of the power grid.
