TECHNICAL FIELD

[0002] In the existing power distribution area operation process, the power scheduling of the power distribution area mainly relies on fixed control strategies or simple threshold adjustment, which is insufficient in adapting to node voltage fluctuations, load imbalance and sudden power demand. In the energy storage charging and discharging scheduling link, it mainly relies on static capacity allocation or fixed priority strategy, and it is difficult to respond to sudden load mutations and power transmission changes between nodes in time. At the same time, for the differentiated load demand of different structures of working nodes in the power distribution area, it is difficult to balance the power regulation of high-load pressure nodes and the overall voltage stability, and lacks dynamic perception and accurate analysis of node state, potential load bottleneck and communication interruption. The above problems lead to unreasonable power distribution of working nodes in the power distribution area. SUMMARY

[0019] As described in the background section, a distribution substation is the basic unit for managing low-voltage distribution networks in a power system. It typically refers to the power supply area from the high-voltage head of a single distribution transformer to the user, including distribution transformers, distribution boxes, low-voltage lines, and user-side equipment. Distribution substations enable power distribution management. A distribution substation has multiple working nodes, exhibiting multiple topologies and frequent load fluctuations. In the current operation of distribution substations, energy storage systems and distributed load dispatch mainly rely on fixed control strategies or simple threshold adjustments, which are insufficiently adaptable to voltage fluctuations, load imbalances, and sudden power demands at the working nodes. In the energy storage charging and discharging scheduling stage, static capacity allocation or fixed priority strategies are often relied upon, making it difficult to respond promptly to sudden load changes and power transfer variations between working nodes. This results in low utilization of energy storage resources and an inability to finely adjust the voltage qualification rate of the substation. Meanwhile, the presence of working nodes with different topologies within the distribution transformer area makes it difficult to balance power regulation of individual working nodes with overall voltage stability. The lack of dynamic awareness and precise analysis of working node status, potential load bottlenecks, and communication interruptions further hinders energy storage charging and discharging scheduling from achieving high-priority working node protection and overall optimized operation of the distribution transformer area. These issues result in an unreasonable power allocation among working nodes within the distribution transformer area.

[0020] In view of this, embodiments of this application propose a power allocation method for distribution radio areas, referring to... Figure 1 This includes the following steps: Step 101: Obtain the structural information, first current voltage information, and first current load information corresponding to each working node in the power distribution area. Based on the structural information, first current voltage information, and first current load information corresponding to each working node, perform multiple rounds of power allocation operations. Each round of power allocation operation is executed as follows.

[0021] In this step, the distribution transformer area includes multiple working nodes, which are used to complete the received tasks. In existing technologies, the power allocation of working nodes in the distribution transformer area mainly relies on fixed control strategies or simple threshold adjustments. However, the load of working nodes fluctuates frequently, and existing technologies are insufficiently adaptable to voltage fluctuations, load imbalances, and sudden power demands, resulting in unreasonable power allocation within the distribution transformer area. This application dynamically adjusts the power corresponding to each working node. First, it acquires the structural information, first current voltage information, and first current load information corresponding to each working node in the distribution transformer area. By acquiring this information, a comprehensive understanding of the power consumption of each working node is obtained. Based on the structural information, first current voltage information, and first current load information corresponding to each working node, multiple rounds of power allocation operations are performed. The power allocation is flexibly adjusted according to the actual needs of the working nodes to ensure the most efficient use of resources. Dynamically adjusting the power allocation avoids a series of problems detrimental to system stability caused by overload.

[0022] Step 1021: In response to determining that the distribution radio area is in a working state, for each working node, the priority of the working node is determined based on the structural information and the first current voltage information corresponding to the working node.

[0023] In this step, while the distribution substation is operational, real-time power monitoring is performed on each working node within the substation. The stability of the working nodes directly affects the system's stability. Based on the analysis of structural and voltage information, the priorities of the working nodes are determined, identifying those with a relatively significant impact on system stability. For example, priorities include high, medium, and low priorities. By determining the priorities of the working nodes, all nodes are categorized according to their importance, achieving a precise quantification of the impact of each working node on the overall system stability. This provides a basis for the subsequent power allocation order of the working nodes, ensuring the operational stability of high-priority working nodes.

[0024] Step 103: Based on the first current voltage information and the first current load information corresponding to each working node, determine the power allocation scheme corresponding to each working node.

[0025] In this step, voltage and load information are core data reflecting the real-time operating status of the working nodes. Together, they determine the match between the node's carrying capacity and power requirements. For example, excessive voltage deviation or fluctuation may cause node failure, while overload or underload leads to resource waste. Dynamically analyzing these two data points for each working node determines the corresponding power allocation scheme. By accurately quantifying the power deficit of each working node, a differentiated allocation strategy can be developed that avoids overload risks while improving energy utilization efficiency.

[0026] Step 104: Based on the power allocation scheme and priority corresponding to each working node, perform power allocation for each working node.

[0027] In this step, priority reflects the critical impact of each working node on system stability, and the power allocation scheme clarifies the actual power requirements of each working node. The combination of these two allows for precise control, ensuring "allocation on demand and prioritizing key nodes." When a high-priority working node is anticipated to have power requirements, power is allocated to it first to prevent system crashes due to insufficient power. Ensuring the stable operation of critical working nodes improves the overall system resilience. Based on the priority of each working node, its corresponding power allocation scheme is used to fill any power gaps, ensuring the stable operation of high-priority working nodes and thus guaranteeing system stability.

[0028] Step 105: After a predetermined time, obtain the second current voltage information and the second current load information corresponding to each working node, and use the second current voltage information and the second current load information corresponding to each working node as the first current voltage information and the first current load information in the next round of power allocation operation, and execute the next round of power allocation operation.

[0029] In this step, the load of the working nodes fluctuates. After a period of time, it is necessary to reassess whether there is a power gap among the working nodes in the distribution area, and to allocate power to the working nodes with power gaps. The predetermined time is determined based on historical experience. Therefore, after the predetermined time, the second current voltage information and the second current load information corresponding to each working node are obtained. These second current voltage information and second current load information are used as the first current voltage information and first current load information in the next round of power allocation operation, and the next round of power allocation operation is executed. By periodically updating data and dynamically allocating power, the system addresses the load changes of the working nodes. Based on the real-time task load of each node, more power is allocated to nodes with heavier loads, enabling them to process tasks faster, thereby improving the task processing speed and efficiency of the entire system. Figure 2 As shown, from Figure 2As can be observed, within the 51-second time window, the actual dispatched power (solid black line) exhibited frequent and significant fluctuations. Despite these drastic power changes, the actual power remained strictly limited below the capacity limit (dashed line) throughout the entire process. This indicates that the energy storage charging and discharging scheduling successfully achieved effective management of bottleneck operating nodes, preventing system overload and ensuring operational safety and stability. By executing the next round of power allocation operations, dynamic power allocation was achieved, ensuring the rationality of power allocation and realizing dynamic management of energy storage charging and discharging, thereby improving the voltage qualification rate of the distribution substation.

[0030] Step 1022: In response to determining that the distribution radio area is not in the operating state, exit at least one round of power allocation operation.

[0031] In this step, when the distribution area is not in operation, there is no need to monitor the power of the working node, and the operation exits at least one round of power allocation, ensuring the closed-loop execution of dynamic power allocation.

[0032] The above scheme obtains the structural information, first current voltage information, and first current load information corresponding to each working node in the distribution transformer area. Based on the structural information, first current voltage information, and first current load information corresponding to each working node, multiple rounds of power allocation operations are performed. Each round of power allocation operation is executed as follows: In response to determining that the distribution transformer area is in a working state, for each working node, based on the structural information and first current voltage information corresponding to the working node, the priority of the working node is determined to achieve the purpose of accurately quantifying the impact of each working node on the overall system stability. Based on the first current voltage information and first current load information corresponding to each working node, a power allocation scheme corresponding to each working node is determined. By accurately quantifying the power gap of each working node, a differentiated allocation strategy that avoids overload risk and improves energy utilization efficiency is formulated. Based on the power allocation scheme and priority corresponding to each working node, power is allocated to each working node to ensure that high-priority working nodes can work stably, thereby ensuring the stability of the system. After a predetermined time, the second current voltage information and the second current load information corresponding to each working node are obtained. These two information are then used as the first current voltage information and the first current load information in the next round of power allocation operation. This process enables dynamic power allocation, ensuring its rationality. In response to determining that the distribution area is not in the operating state, at least one round of power allocation operation is exited, ensuring closed-loop execution of dynamic power allocation.

[0033] In some embodiments, determining the power allocation scheme for each working node based on the first current voltage information and the first current load information corresponding to each working node includes: determining at least one bottleneck working node among all working nodes based on the first current voltage information and the first current load information corresponding to each working node, wherein the idle load of the bottleneck working node is less than a predetermined idle load; determining the power allocation scheme of the at least one bottleneck working node as a first power allocation scheme; and determining the power allocation schemes of the other working nodes among all working nodes excluding the at least one bottleneck working node as a second power allocation scheme. In this embodiment, different working nodes are affected by various factors during actual operation, such as different tasks being performed, resulting in differences in load and voltage. By obtaining the first current voltage information, the voltage environment of each node can be accurately grasped, as voltage stability directly affects the working efficiency and equipment safety of the working nodes; while the first current load information directly reflects the workload currently undertaken by the node. Based on these two types of information, at least one bottleneck working node is identified among all working nodes. The bottleneck working node refers to a node whose idle load is less than a predetermined idle load, indicating a high load pressure and near-limit resource utilization in the current system. After identifying the bottleneck working node, the first power allocation scheme is determined as the power allocation scheme for the bottleneck working node. The bottleneck working node is already under relatively tight load, requiring more precise and reasonable power allocation to ensure its stable operation and avoid performance degradation or even failure due to insufficient power, thereby affecting the reliability of the entire system.

[0034] Simultaneously, the second power allocation scheme is determined to be the power allocation scheme for all working nodes except the bottleneck node. Other working nodes have relatively more idle load and greater power adjustment capacity. By differentiating the power allocation schemes, targeted power management can be carried out according to the actual conditions of different nodes, achieving optimized allocation of system resources. Differentiating the power allocation schemes for working nodes ensures that power allocation is more closely aligned with the actual needs of each node, avoiding power waste or unreasonable allocation, ensuring the continuous and stable operation of the bottleneck node with adequate power, reducing the risk of failures caused by power issues, and ultimately improving the overall performance and service quality of the entire power distribution system.

[0035] In some embodiments, before acquiring the second current voltage information and the second current load information corresponding to each working node after a predetermined time, the method includes: in response to determining that at least one bottleneck working node has detected a communication interruption, acquiring interruption data, and performing power allocation on the at least one bottleneck working node based on the interruption data; acquiring the third current voltage information corresponding to each working node, and calculating the voltage qualification rate corresponding to the distribution area based on the third current voltage information corresponding to each working node; in response to determining that the voltage qualification rate is greater than a predetermined value, acquiring the third current load information corresponding to each working node; and performing power allocation on each working node based on the third current load information corresponding to each working node. In this embodiment, the bottleneck node, due to its high load, may generate a large amount of communication data. When network bandwidth is limited, this large amount of data may cause network congestion, preventing timely transmission of communication data, or even causing packet loss, ultimately leading to communication interruption. This embodiment can dynamically detect whether the bottleneck node has experienced a communication interruption, achieving continuity and traceability of charge and discharge scheduling, and improving the system's responsiveness to abnormal operating states. When it is determined that at least one bottleneck node has experienced a communication interruption, by acquiring the interruption data, key information such as the node's state at the time of the interruption can be understood. Based on this, power allocation can be performed to maximize the protection of the bottleneck node's power requirements under special circumstances and maintain its basic operation. By allocating power to the bottleneck node, the load on the bottleneck node is relatively reduced, ensuring the stability of the bottleneck node.

[0036] After a communication interruption, the energy storage charging and discharging tasks that the bottleneck working node was originally executing may not have been completed. Continuing to use the instructions before the interruption could lead to energy storage scheduling exceeding constraints or over-scheduling. Therefore, the system must confirm whether the current distribution area is in a "safe / qualified" state before deciding how to continue scheduling. Thus, the third current voltage information corresponding to each working node is obtained, and based on this information, the voltage qualification rate for the distribution area is calculated. The voltage qualification rate is a key indicator for measuring system voltage quality. Only by accurately understanding the voltage qualification rate can we fully understand whether the system voltage is within a reasonable range, providing a basis for subsequent operations.

[0037] The voltage qualification rate is calculated through the following steps: For each working node, based on its corresponding third current voltage information and the predetermined qualified voltage range, it is determined whether the working node is a qualified working node; the total number of qualified working nodes is counted to obtain the number of qualified working nodes; the voltage qualification rate is determined by dividing the number of qualified working nodes by the preset total number of working nodes in the distribution transformer area. For example, the node's rated voltage V... _nom Based on this, the pass / fail threshold is set as V. _nom±5%, for example, V _nom =230V, then the acceptable range is 218.5–241.5V. The system sequentially compares whether the real-time voltage of each node falls within this range, marks the nodes that meet the criteria as qualified nodes, and records their corresponding time step information and node identifier for subsequent voltage quality statistics and analysis. The system can also incorporate a power allocation method for distribution substations. Assuming the total number of working nodes in the distribution substation is 50, the system determines the acceptable range based on the third current voltage information of the working nodes, selecting qualified working nodes within ±5% of the rated voltage. After data recovery from the interruption, 46 nodes have voltages within ±5% of the rated value. The voltage qualification rate is determined by dividing the number of qualified working nodes by the preset total number of working nodes in the distribution substation. The system will then calculate the number N of the selected qualified working nodes. _qualified The total number of working nodes N preset in the distribution radio area _total The voltage qualification rate R is obtained by performing a division calculation. _qual =N _qualified / N _total ×100%. The voltage qualification rate is 92%. Based on this qualification rate, the energy storage charging and discharging power will be increased by 0.3–0.5kW at the bottleneck operating node and decreased by 0.1–0.2kW at other operating nodes, thereby generating optimized energy storage charging and discharging scheduling data, which will provide a basis for subsequent balanced operation of the distribution area and voltage stability. Furthermore, assuming there are 15 nodes in the distribution area, the third current voltage information for each working node is obtained: the third current voltage information for node 1 is: [229,231,230,228,232,234,229,230,231,233]; the third current voltage information for node 2 is: [220,222,221,219,223,225,224,221,222,220]; the third current voltage information for node 3 is: [235,236,234,233,237,238,236,235,234,236]; the voltages of the remaining nodes are similar. It is determined that nodes 1, 3, and 5–8 are within the rated voltage ±5% range, and a total of 8 nodes are marked as qualified nodes. Nodes 2, 4, and other nodes are excluded because their voltages are below 218.5V or above 241.5V. For example, if the total number of working nodes in a distribution substation is preset to 20, and 15 of them are found to be qualified, then the voltage qualification rate is 75%. Alternatively, if the total number of working nodes in a distribution substation is preset to 15, and 10 of them are qualified, then the calculated voltage qualification rate is 10 / 15 ≈ 66.7%. This value is used to generate a voltage quality report for the substation and to assist in deciding whether load adjustments or voltage optimization are needed for certain nodes.

[0038] When the voltage qualification rate is determined to be greater than the predetermined value, it indicates that the overall system voltage condition is good. At this point, the third current load information corresponding to each working node is obtained, and power allocation is performed based on it. This is because, under the premise of qualified voltage, load information can more accurately reflect the actual working needs of each node. Power allocation based on load conditions can make power allocation more accurate and reasonable, avoid power waste or under-allocation, and further improve the system's operating efficiency. During the scheduling optimization process, the voltage qualification rate is calculated based on the updated scheduling resource status, and the energy storage charging and discharging scheduling quantity is adjusted based on the voltage qualification rate to generate optimized scheduling data, realizing dynamic optimization of distribution area voltage quality and efficient utilization of energy storage resources. It should be noted that in the scheduling recovery phase, the distribution area status is reconstructed using interrupted data, the scheduling task progress is restored, and the scheduling resource status is updated, realizing unified management of distribution area status and scheduling tasks, ensuring the stability and continuity of energy storage system operation.

[0039] Through this embodiment, on the one hand, the special handling of communication interruptions at bottleneck working nodes enhances the system's ability to cope with emergencies, improves the system's reliability and stability, and reduces the probability of accidents such as power outages caused by node failures; on the other hand, power allocation based on voltage qualification rate and load information realizes the optimized allocation of system resources, improves power utilization efficiency, reduces energy loss, and also helps to extend equipment lifespan, reduce operation and maintenance costs, and improve the overall performance and service quality of the entire power distribution system.

[0040] In another embodiment provided in this application, communication interruption is determined by the following method: continuously collecting multiple signal strengths of the communication link; in response to determining that a predetermined number of consecutive signal strengths are all below a signal strength threshold, determining that the communication link is in an unstable state; in response to determining that the communication link is in an unstable state, obtaining the handshake acknowledgment code corresponding to the communication link; counting the number of failed messages sent by the working node based on the handshake acknowledgment code; and identifying a communication interruption based on the number of failed messages. For a communication link determined to be in an unstable state, the system records each handshake acknowledgment code (ACK / NACK) and its corresponding sending and receiving time of the working node, and counts the number of failed messages sent by the working node. If no ACK is received for three consecutive times, the message is considered to have failed to be sent, thereby identifying a communication interruption.

[0041] For example, the system acquires the instantaneous signal strength (RSSI / signal level) of the link at a sampling frequency of 1Hz via a wireless module or wired interface, and records the continuous sampled values. When the signal strength is lower than a preset threshold (e.g., -85dBm) for three consecutive sampling periods, the link is determined to be in an unstable state, and the instability start time, duration, and involved node IDs are recorded. For example, assuming that the signal strength values ​​collected for 10 consecutive sampling periods are [-87, -88, -90, -82, -89, -91, -86, -84, -92, -88]dBm, and the first to third periods are continuously lower than the threshold -85dBm, the link is determined to be in an unstable state in the first to third sampling periods, which is used for subsequent communication anomaly analysis. Assuming that in the potential load bottleneck node, the load of 5 nodes reaches 85%-95% of the rated power, and the adjustable capacity range of the energy storage unit is 2kWh-5kWh; the energy storage charging and discharging power is allocated according to priority, and the time window of each instruction is 0.5-1s; within 10 seconds of continuous monitoring, a short-term interruption of the communication link of 2 nodes is detected and the breakpoint data is recorded for subsequent task recovery.

[0042] The system aligns interrupted data with the node status time series in the power resource information, fills in missing data during the interruption period, and generates an incomplete charging and discharging scheduling sequence. First, the system collects the historical status time series of each working node in the power resource information, including parameters such as current, voltage, and energy storage unit SOC (State of Charge), and aligns it with the interrupted data. For missing data during the interruption period, linear interpolation or a time series filling method based on weighted nearest neighbor values ​​is used to fill in the missing data, generating a continuous incomplete charging and discharging scheduling sequence. During the completion process, the confidence index of each completed data entry (e.g., average interpolation error <0.5A) is recorded, and the generated sequence is synchronized to the entire network scheduling database by timestamp to ensure consistency in subsequent analysis and control. Based on the incomplete charging and discharging scheduling sequence, node current information is recovered, and the current transmission path is determined; based on the current transmission path, node load is recorded, and the transformer area status is updated.

[0043] For example, suppose the system contains 10 energy storage nodes, and the missing data lengths during the breakpoint of each node are [3, 5, 2, 4, 6, 3, 5, 2, 4, 3] minutes respectively. After linear interpolation to complete the data, the length of the incomplete charge and discharge scheduling sequence is approximately [63, 125, 42, 88, 153, 67, 112, 44, 95, 69] data points. Each data point contains node voltage, current, and SOC information, providing a continuous data foundation for subsequent charge and discharge recovery and transformer area status updates.

[0044] In some embodiments, determining the priority of a working node based on its corresponding structural information and first current voltage information includes: for each working node, in response to determining that the structural information corresponding to the working node indicates that the working node belongs to a chain topology containing a first number of working nodes, calculating a voltage drop value corresponding to the working node based on the first current voltage information; determining the priority of the working node based on the chain topology, the first number, and the voltage drop value; in response to determining that the structural information corresponding to the working node indicates that the working node belongs to a ring topology containing a second number of working nodes, calculating a voltage deviation value corresponding to the working node based on the first current voltage information; determining the priority of the working node based on the ring topology, the second number, and the voltage deviation value; in response to determining that the structural information corresponding to the working node indicates that the working node belongs to a hybrid topology containing a third number of working nodes, calculating a voltage deviation value corresponding to the working node based on the first current voltage information; and determining the priority of the working node based on the hybrid topology, the third number, and the voltage deviation value. In this embodiment, the voltage distribution and transmission characteristics of working nodes differ under different topologies. Specifically, in a chain topology, working nodes are connected in series, and the voltage gradually decreases with transmission. A ring topology is relatively complex, with voltage distribution affected by multiple paths. A hybrid topology possesses multiple characteristics. Furthermore, different topologies contain different numbers of working nodes, resulting in varying degrees of impact on the overall system. The first current voltage information directly reflects the current voltage state of the working nodes and is a key indicator for assessing their operational status. Therefore, for a chain topology, calculating the voltage drop based on the first current voltage information clearly reveals the voltage loss of the working nodes in this structure. Combining the first quantity and the characteristics of the chain topology to determine priorities, subsequent work nodes with significant voltage drops and critical impacts on the chain structure can be prioritized. For a ring topology, calculating the voltage deviation value reveals the degree to which the voltage deviates from the normal value. Determining priorities based on the second quantity and the characteristics of the ring topology helps to prioritize work nodes with significant voltage deviations and important impacts on the stable operation of the ring structure. For hybrid topologies, voltage deviation values ​​are also calculated. Priorities are determined by combining the third quantity and the characteristics of the hybrid topology, which allows for the reasonable allocation of resources and ensures the stable operation of critical working nodes in the hybrid topology.

[0045] For example, when a working node belongs to a ring node topology, with ≥3 and ≤12 ring nodes and a node voltage deviation ≤±5%, the working node is determined to be a high-priority node; when a working node belongs to a ring node topology, with ≥3 and ≤12 ring nodes and a node voltage deviation ≤±5%, the working node is determined to be a high-priority node; when a working node belongs to a chain topology, with ≥2 and ≤8 nodes along the link and a node voltage drop not exceeding 5%, the working node is determined to be a medium-priority node; when a working node belongs to a hybrid topology, with 3-8 ring nodes, 2-6 link nodes, and a ring node voltage deviation ≤5%, the working node is determined to be a low-priority node. Based on the characteristics of different topologies and the number of working nodes, the importance of each working node in the system can be assessed more accurately, making priority determination more scientific and reasonable. At the same time, based on the first current voltage information, the actual operating status of the working nodes can be reflected in real time, ensuring that the priority is closely integrated with the actual situation. Thus, in resource allocation, fault handling and other operations, the normal operation of key working nodes is prioritized, improving the stability and reliability of the entire power distribution system, reducing the probability of accidents caused by working node failures or abnormal operation, and improving the overall operating efficiency and service quality of the system.

[0046] For example, suppose there are a total of 30 ring nodes in the network, distributed in 4 rings, with 4, 5, 6, and 7 ring nodes respectively, and the node voltage deviation range is [-3.2%, +4.1%]. According to the judgment criteria, a total of 18 nodes are marked as high-priority nodes. Among them, ring 1 contains 4 nodes (ID: 1, 2, 3, 4), ring 2 contains 5 nodes (ID: 6, 7, 8, 9, 10), ring 3 contains 6 nodes (ID: 12, 13, 14, 15, 16, 17), and ring 4 contains 3 nodes (ID: 19, 20, 21). The remaining ring nodes are not marked because the number of ring nodes or the voltage deviation exceeds the threshold.

[0047] For example, when a working node belongs to a chain topology and the number of working nodes along the link is ≥2 and ≤8, and the node voltage drop does not exceed 5%, the working node is determined to be a medium-priority working node. Specifically, for chain nodes, the number of working nodes and the voltage drop of each node are counted sequentially along the link direction. If the number of working nodes in the link is 2 to 8 and the node voltage drop does not exceed 5%, then all working nodes in the link are marked as medium-priority working nodes, and the node ID, link start and end points, node voltage, and link sequence are recorded for link load management and dynamic power allocation. Assuming 5 chain links are detected, with a total of 18 working nodes, the number of working nodes is 2, 3, 4, 5, and 4 respectively, and the node voltage drop range is [0.5%, 4.8%]. Therefore, all 18 working nodes are determined to be medium-priority working nodes. Among them, link 1 contains 2 nodes (ID: 22, 23), link 2 contains 3 nodes (ID: 24, 25, 26), link 3 contains 4 nodes (ID: 27, 28, 29, 30), link 4 contains 5 nodes (ID: 31, 32, 33, 34, 35), and link 5 contains 4 nodes (ID: 36, 37, 38, 39).

[0048] For example, when a working node belongs to a hybrid topology and has 3-8 working nodes in the loop, 2-6 working nodes in the link, and a loop node voltage deviation ≤5%, the working node is identified as a low-priority working node. For hybrid working nodes, the number of nodes in both the loop and link portions, as well as the voltage deviation within the loop, are analyzed simultaneously. If the number of working nodes in the loop is between 3 and 8, the number of working nodes in the link is between 2 and 6, and the loop node voltage deviation does not exceed 5%, the hybrid working node is marked as a low-priority working node, and its working node ID, loop number, link number, node voltage, and adjacent node information are recorded for hybrid topology power regulation and security isolation strategy design. Assuming there are 10 mixed working nodes in the network, with 3, 4, 5, 4, and 3 working nodes in the loops and 2, 3, 4, 3, and 2 working nodes in the links, and the voltage deviation range of the loop nodes is [-2.1%, +4.5%], all 10 mixed working nodes are determined to be low-priority working nodes, with node IDs {40, 41, 42, 43, 44, 45, 46, 47, 48, 49}, and the loop numbers and link numbers correspond to the topology order.

[0049] High-priority, medium-priority, and low-priority working nodes are designated as node priorities. After determining the priority of working nodes based on their corresponding structural information and the first current voltage information, the marked working nodes are sorted according to high, medium, and low priorities to generate a node priority list. Each working node's ID, topology type, priority level, and key electrical parameters are recorded, providing a basis for power allocation, energy storage scheduling, and fault isolation in low-voltage flexible interconnection networking. For example, assuming the integrated network contains 18 high-priority working nodes (IDs: 1–4, 6–10, 12–17, 19–21), 18 medium-priority working nodes (IDs: 22–39), and 10 low-priority working nodes (IDs: 40–49), forming a complete node priority structure, where each working node carries topology type, voltage deviation, and information about its loop or link, which can be used for node scheduling strategy simulation and optimization.

[0050] In another embodiment provided in this application, the structural information of the working node can be directly obtained if it exists in the system. If the structural information of the working node does not exist in the system, it needs to be determined in advance. The voltage amplitude and current data of nodes in the distribution substation are continuously collected at a preset sampling frequency. The active power and reactive power of each node are calculated using a measurement unit, and an instantaneous power vector is generated. The adjustable power of energy storage is calculated using the node voltage amplitude and current data. The instantaneous power vector and the adjustable power of energy storage are aligned by timestamp and integrated into power resource information. The power resource information is used to determine the node power flow distribution characteristics. The active power transfer ratio between any two nodes is calculated based on the node power flow distribution characteristics. The node voltage phasor data is extracted based on the power resource information, and the voltage phase angle difference is calculated. For example, if the active power transfer ratio is between 0.15 and 0.35 and the phase angle difference is between 5° and 15°, it is determined that there is an electrical connection between the two nodes. The node connection structure is identified based on the electrical connection relationship, and the low-voltage flexible interconnection network mode is determined. The direction of power transfer at nodes is detected using electrical connections. When the power transfer direction forms a closed loop and the number of loop nodes is ≥3, the group of nodes is considered to form a closed loop and is marked as a ring topology. If the power transfer direction is unidirectional and each node is directly electrically connected to only 1-2 nodes before and after it, the line segment is considered a unidirectional link node and is marked as a chain topology. Regions where both closed loops and unidirectional link nodes exist in the electrical connections are identified and marked as hybrid topologies. Ring topologies, chain topologies, and hybrid topologies are integrated into a node connection structure, and the low-voltage flexible interconnection network mode is determined.

[0051] The power flow distribution characteristics of nodes are determined using power resource information. Based on these characteristics, the active power transfer ratio between any two nodes is calculated. Node voltage phasor data is extracted from the power resource information, and the voltage phase angle difference is calculated. The calculated node power transfer ratio and voltage phase angle difference are then input into the node topology identification module. The module filters node pairs that meet certain conditions according to set threshold rules, such as P... _ij ∈[0.15, 0.35] and Δθ _ij Node pairs ∈ [5°, 15°] are considered to have an electrical connection. An adjacency matrix is ​​then constructed based on the node pair connections, and graph analysis is used to identify the flexible interconnection patterns of the low-voltage distribution network, including ring, radial, and hybrid structures, to support dynamic load scheduling and energy storage optimization. The generated power resource information table is input into the distribution area power analysis module to analyze the active and reactive power flows of each node, calculating the power transfer ratio between nodes in vector form. For example, for each pair of nodes (i, j), its active power P is calculated. _ij The proportion of the total active power at node i is recorded, along with the corresponding timestamp; simultaneously, the voltage phasors of each node are extracted, and the voltage phase angle difference Δθ between nodes is calculated. _ij The analysis module can output a timing record containing node ID, timestamp, power transfer ratio, and voltage phase angle difference, which can be used for subsequent node connection relationship determination and flexible networking mode identification.

[0052] For example, assuming a distribution substation contains 40 nodes, and power resource information shows active power between 0.5–15kW and reactive power between 0.1–3kVar, the calculated active power transfer ratio between nodes is between 0.05–0.4, and the voltage phase angle difference is between 2°–18°. This generates 1200 timestamped data points on node power transfer and voltage phase angle difference, which can be used for substation topology analysis and extraction of electrical coupling features between nodes. If the active power transfer ratio is between 0.15 and 0.35 and the phase angle difference is between 5° and 15°, it is determined that two nodes have an electrical connection. Based on the electrical connection relationship, the node connection structure is identified, and the low-voltage flexible interconnection network mode is determined. For example, assuming that there are 25 pairs of nodes selected, with an average active power transfer ratio of 0.22 and an average phase angle difference of 9.8°, the ring network structure with 10 nodes and the radial structure with 15 nodes are constructed through the adjacency matrix. Based on this, it can be determined that the low-voltage flexible interconnection networking mode of the distribution area is a hybrid structure of ring network and radial structure, which provides a reference for intelligent power distribution scheduling and energy storage control.

[0053] Intelligent measurement units are deployed at all working nodes in the low-voltage distribution network to collect active power, reactive power, and voltage phase information in real time. An electrical connection matrix between nodes is established, and the power transfer direction of each line is inferred based on the power direction. A loop detection algorithm from graph theory is then used to scan the network topology and identify closed loops. For example, assuming the network has 40 working nodes and 3 closed loops are detected, with loop node numbers of 3, 5, and 6 respectively, and loop node IDs {1, 3, 5}, {8, 9, 12, 14, 15}, and {18, 19, 21, 23, 25, 27} respectively, and power directions of clockwise, counterclockwise, and clockwise respectively. If the power transfer direction of a node is unidirectional and each node is only directly electrically connected to 1-2 nodes before and after it, then the line segment is determined to be a unidirectional link node and marked as a ring topology. For the remaining nodes not marked as ring nodes, analyze the number of direct electrical connections and power flow direction of each node. If a node is directly connected to only 1-2 nodes before and after it and the power direction is the same, then mark the node and its adjacent nodes as a chain topology, and record the link start and end points, node ID, and power flow direction for subsequent unidirectional load control and energy storage optimization. For example, assume that 15 of the remaining 20 nodes meet the chain condition, with node IDs {2, 4, 6, 7, 10, 11, 13, 15, 17, 20, 22, 24, 26, 28, 30}, each node is directly electrically connected to only 1-2 nodes before and after it, the average line length is 150m, and the power flow direction is unidirectional.

[0054] Identify areas in electrical connections that simultaneously contain closed loops and unidirectional link nodes, and mark them as hybrid node topologies. Integrate the information of loop nodes and chain nodes to form a complete node connection diagram. Analyze the transition nodes connected to chain nodes around loop nodes to determine whether they belong to both loops and are connected to chain nodes. Nodes that simultaneously meet the conditions are marked as hybrid node topologies, and information such as the ID of each hybrid node, adjacent loop nodes and chain nodes, and power flow direction are recorded to provide data for hybrid topology power regulation and abnormal state identification. For example, suppose 6 working nodes are found to simultaneously belong to loops and chain transition nodes, and are marked as hybrid node topologies. The working node IDs are {5, 8, 12, 16, 21, 26}, the power flow direction is towards the chain line, and the power within the loop is a closed loop.

[0055] All identified node topology information is integrated into a complete node connection structure diagram. Each node is labeled with its topology type, node ID, power flow direction, and adjacent node information. Network visualization diagrams and data tables are generated through topology analysis, providing a foundation for the design of low-voltage flexible interconnection network modes. Based on the complete node connection structure, the low-voltage flexible interconnection network mode is determined, including ring network stability, chain load regulation, and hybrid node power allocation strategies. The low-voltage flexible interconnection network mode is determined to be "ring network + chain + hybrid," with loop power circulation, chain nodes exhibiting unidirectional flow, and hybrid nodes serving as transition nodes between loops and links. This provides a topology basis for distribution area power regulation, energy storage optimization, and fault isolation. The voltage values ​​of all ring nodes in the low-voltage distribution network are monitored in real time. The percentage of node voltage deviation relative to the nominal voltage is calculated, and the number of nodes within the loop is counted. When the number of loop nodes is between 3 and 12 and the voltage deviation does not exceed ±5%, all nodes within the loop are marked as high-priority nodes. The ID, voltage value, loop number, and number of loop nodes for each node are recorded for subsequent power regulation and load priority management.

[0056] In some embodiments, determining at least one bottleneck working node among all working nodes based on the first current voltage information and the first current load information corresponding to each working node includes: for each working node, determining the adjustable load information corresponding to the working node based on the first current voltage information and the first current load information corresponding to the working node; and determining the working node as the bottleneck working node in response to determining that the difference between the first current load information and the adjustable load information is less than a predetermined difference. In this embodiment, the first current voltage information of the working node reflects the power supply voltage status at its location, while the first current load information reflects the actual workload currently undertaken by the node. These two are interrelated and jointly affect the operating status of the working node. Adjustable load information is determined based on the first current voltage information and the first current load information corresponding to the working node. The adjustable load information is determined using the following formula: C _adj =α×P _load +β×ΔV, where α and β are adjustment coefficients, P _load The first current load information represents the real-time load of the nodes, and ΔV represents the node voltage deviation calculated using the first current voltage information. The calculated adjustable energy storage capacity is matched with the load data of the corresponding nodes to identify bottleneck working nodes, i.e., nodes whose load is close to or exceeds the adjustable capacity, and the matching coefficients such as node ID, priority level, load value, and adjustable energy storage capacity are recorded.

[0057] Adjustable load information is a quantitative assessment of the additional or adjusted load capacity that a working node can bear under voltage conditions. It comprehensively considers the voltage constraint on the load and the node's own adjustment potential. When the difference between the first current load information and the adjustable load information is less than a predetermined difference, it means that the actual load of the working node has approached or even exceeded its adjustable range under the current voltage. Continuing to increase the load may lead to problems such as voltage instability, equipment overheating, performance degradation, or even failure. In this case, it is reasonable and timely to identify it as a bottleneck working node. The predetermined difference is determined through historical experience. By comparing the difference between the first current load information and the adjustable load information with the predetermined difference, working nodes with loads approaching their limits and high operational risks are accurately identified, so as to carry out targeted power allocation to bottleneck nodes in the future. By periodically collecting power resource information of distribution substations and combining it with the low-voltage flexible interconnection networking mode for node division, a refined characterization of the load characteristics and interconnection relationships of substation nodes is achieved, providing an accurate and complete data foundation for subsequent energy storage scheduling.

[0058] For example, suppose there are 50 working nodes in the network, 15 high-priority working nodes, 25 medium-priority working nodes, and 10 low-priority working nodes. The load values ​​of the working nodes range from [8kW, 32kW], and the corresponding adjustable energy storage capacity ranges from [10kWh, 35kWh]. According to the matching calculation, a total of 12 working nodes are identified as bottleneck working nodes, including 6 high-priority working nodes (ID: 1, 3, 7, 8, 10, 12), 5 medium-priority working nodes (ID: 22, 25, 28, 30, 33), and 1 low-priority working node (ID: 41). Their load accounts for 85%–98% of the adjustable capacity.

[0059] In another embodiment provided in this application, current information corresponding to the first current voltage information of the working node is obtained. Based on the first current voltage information and current information of the working node, the active power corresponding to the working node is calculated. Based on the first current voltage information of the working node, the voltage fluctuation value corresponding to the working node is calculated. In response to determining that the active power is greater than a preset power threshold and the voltage fluctuation value exceeds a predetermined voltage fluctuation range, the working node is identified as a bottleneck working node. For example, when the voltage fluctuation of the working node exceeds ±5% and the rate of change of active power per unit time (ΔP / Δt) exceeds a threshold (e.g., 0.8kW / s), the working node is marked as a potential load bottleneck, and the occurrence time, node ID, voltage deviation value, and power change rate are recorded.

[0060] For example, suppose there are 12 high-load pressure nodes. Among them, the voltage deviations of nodes 2, 7, 22, 28, and 41 during the monitoring period are [–5.2%, +5.5%, +6.1%, –5.8%, +5.3%], and the corresponding active power change rates are [0.85, 0.92, 1.05, 0.88, 0.97] kW / s, respectively. All of them exceed the ±5% voltage deviation and 0.8 kW / s change rate thresholds. Therefore, these 5 working nodes are determined to be bottleneck working nodes, and the remaining 7 working nodes are not determined because they do not simultaneously meet the voltage deviation and power change rate conditions.

[0061] In some embodiments, the step of allocating power to each working node based on the power allocation scheme and priority corresponding to each working node includes: sorting each bottleneck working node in descending order of priority based on the priority corresponding to each bottleneck working node to obtain a sequence containing multiple bottleneck working nodes, and allocating power to each bottleneck working node in the sequence in sequence according to the first predetermined power in the first power allocation scheme; and allocating power to the other working nodes according to the second predetermined power in the second power allocation scheme. In this embodiment, bottleneck nodes are already under near-limit load and resource constraints, making them relatively vulnerable and significantly impacting overall system operation. They are prioritized based on their respective priorities, with higher priorities reflecting their importance in system stability and meeting critical load demands. Allocating the first predetermined power in the first power allocation scheme according to priority ensures that the most critical and urgently needed bottleneck nodes receive sufficient power first. The first predetermined power is determined based on historical experience. This prevents performance degradation or even failure of these nodes due to insufficient power, thus avoiding a chain reaction throughout the system and ensuring the stable operation of the core components. Prioritizing the power needs of bottleneck nodes significantly reduces the risk of system collapse due to local node failures, improving the reliability and anti-interference capabilities of the entire power distribution system. Regarding resource utilization efficiency, differentiating the power allocation methods for bottleneck nodes from other nodes makes power allocation more precise and rational, fully utilizing system power resources, reducing unnecessary power losses, and improving energy efficiency.

[0062] The remaining working nodes will be allocated power according to the second predetermined power in the second power allocation scheme, where the second predetermined power is determined based on historical experience. It should be noted that since other working nodes have relatively more idle load and adjustment space, they may not be allocated power, and the second predetermined power will be zero. The second power allocation scheme can be rationally planned based on factors such as the overall system operation status and remaining power resources, achieving optimized system power configuration while meeting the basic operational needs of these nodes. This ensures that all working nodes have an appropriate power supply while avoiding power waste or unreasonable allocation.

[0063] In some embodiments, before obtaining the second current voltage information and the second current load information corresponding to each working node, the method further includes: for each bottleneck working node, obtaining the priority of all tasks to be executed in the bottleneck working node, and adjusting the order of all tasks to be executed based on the priority of all tasks to be executed. In this embodiment, the load of the bottleneck worker node is limited. If tasks are not processed according to priority, low-priority tasks may consume resources, preventing high-priority critical tasks from being executed in a timely manner. To ensure that high-priority tasks in the bottleneck worker node are processed smoothly, the priority of all pending tasks in each bottleneck worker node is obtained. Based on the priority of all pending tasks, the order of all pending tasks is adjusted, prioritizing the execution of high-priority tasks in time periods with sufficient capacity. The charging and discharging instructions of the later time window are appended to the end of the execution queue of the previous time window, thus forming a continuous energy storage scheduling sequence. At the same time, the node ID, priority, planned start time, planned end time, and estimated charging and discharging amount of each task are recorded. Subsequent bottleneck worker nodes execute the tasks in the adjusted order in sequence, so that the limited resources of the bottleneck worker node are accurately matched to the tasks that need them most.

[0064] For example, suppose there are 10 bottleneck working nodes in the network, each bottleneck working node corresponds to 3-5 charging and discharging tasks, and after sorting, a continuous energy storage scheduling sequence of 42 instructions is generated, including 18 high-priority node tasks, 16 medium-priority node tasks, and 8 low-priority node tasks. The time window is 10 seconds, and the charging and discharging amount of the tasks is within the range of [1.2kWh, 4.5kWh]. The tasks in the execution queue are arranged in a preset order to ensure that the time windows are connected continuously.

[0065] It should be noted that if a discontinuity in the energy storage capacity allocation of the energy storage scheduling sequence is detected, low-priority charging tasks will be postponed, and the charging and discharging power will be dynamically adjusted according to a predetermined step to allocate the energy storage charging and discharging scheduling amount. For example, the predetermined step is 0.1s–1s. For nodes in the energy storage scheduling sequence where capacity discontinuity or peak values ​​exceed limits, after the system detects the gap or overload, low-priority charging tasks will be postponed, and the charging and discharging power adjustment amount will be calculated for each task according to a predetermined step to gradually compensate for the gap or disperse the load peak, ensuring the smooth execution of the continuous energy storage scheduling sequence. At the same time, the power adjustment value and task completion time of each step will be recorded.

[0066] For example, suppose that in the continuous scheduling sequence, the energy storage capacity of tasks 3, 7, and 10 is found to be discontinuous, with total gaps of 0.35kWh, 0.48kWh, and 0.42kWh, respectively. The low-priority tasks are delayed by 0.5–0.8s, and the dynamic power step adjustment range is 0.2–1.0kW. In the end, the capacity smoothness of the continuous energy storage scheduling sequence is improved to more than 95%, and all tasks are successfully completed within the predetermined time window.

[0067] In some embodiments, after exiting at least one round of power allocation operation, the method further includes: performing statistical analysis on all voltage information and all load information corresponding to each working node. In this embodiment, all voltage and load information corresponding to each working node is statistically analyzed to provide data support for subsequent scheduling optimization and real-time control. Furthermore, the system traverses each time step of the incomplete scheduling sequence, calculates the actual charging and discharging current of each node based on the node topology and the equivalent circuit model of the energy storage unit, and constructs a current transfer matrix to describe the current flow between nodes. Simultaneously, based on the calculated current data, the system statistically analyzes the load status (current and power) of each node at each time step and updates the transformer area status based on the node load, including available capacity, load distribution, and overload risk indicators, providing data support for subsequent scheduling optimization and real-time control.

[0068] For example, assuming a distribution substation contains 5 main operating nodes, the current distribution (in A) of the operating nodes over 5 consecutive time steps is obtained through sequence recovery calculation, such as: Time steps 1–5: Node 1: 2.5, 2.7, 2.6, 2.8, 2.5; Node 2: 1.8, 1.5, 1.9, 1.6, 1.7; Node 3: 0.0, 0.0, 0.0, 0.0, 0.0; Node 4: 3.2, 3.0, 3.1, 3.3, 3.2; Node 5: 2.0, 2.1, 2.2, 2.0, 2.1. Through this current transmission path analysis, the system determines that Node 3 is in an unloaded state, while Nodes 1 and 4 have high loads. The system then updates the substation status parameters, such as available capacity, overload alarm flags, and power supply capacity, providing accurate data for subsequent substation operation optimization and abnormal state early warning.

[0069] In addition, an intelligent measurement unit is installed at each node in the distribution substation. This unit can collect voltage amplitude and current signals in real time and automatically record timestamps. The sampling frequency is set to a predetermined sampling frequency, for example, 3Hz, and continuous acquisition mode is enabled. The internal calculation module of the measurement unit generates active power and reactive power based on the collected voltage and current data, and simultaneously generates instantaneous power vectors in vector form. Each vector includes node ID, sampling time, voltage amplitude, current amplitude, active power, and reactive power. The data is uploaded to the substation dispatch center database in real time via the local area network, forming a complete power information set that can be used for load analysis and dispatch optimization. For example, assuming the distribution substation contains 50 nodes, the voltage amplitude is between 0.95–1.05 pu, the current amplitude is between 10–200A, the active power collected by the measurement unit is distributed between 0.5–15kW, and the reactive power is distributed between 0.1–3kVar, a total of 1200 timestamped instantaneous power vector data are collected, which can be used to analyze the power flow distribution and load change trends in the substation.

[0070] The adjustable power of energy storage is calculated using node voltage amplitude and node current data. The instantaneous power vector and the adjustable power of energy storage are aligned by timestamp and integrated into power resource information. The collected node voltage, current, and calculated active / reactive power data are input into the energy storage management unit (EMS). The EMS calculates the adjustable power sequence of energy storage based on real-time node power and energy storage unit status, including the chargeable and dischargeable power values ​​and corresponding timestamps. Subsequently, the instantaneous power vector and the adjustable power of energy storage are aligned one by one by timestamp. A complete power resource information table is generated through the data integration module, which includes node ID, timestamp, voltage amplitude, current amplitude, active power, reactive power, and adjustable power of energy storage. This table is uploaded to the dispatch analysis platform in real time, providing real-time data support for dynamic dispatch of distribution areas, load forecasting, and energy storage optimization.

[0071] For example, assuming the total capacity of the energy storage unit in the distribution area is 4kWh and the adjustable charging and discharging power is 1.5kW, and the data is aligned with a time step of 0.25 seconds, a total of 600 time-series records are generated. In the integrated power resource information table, the voltage of each node is between 0.96-1.04pu, the current is between 12-180A, the active power is between 1-14kW, the reactive power is between 0.2-2.5kVar, and the adjustable power of energy storage is between -1.5kW and 1.5kW. It can be directly used for distribution area load regulation strategy and energy storage dispatch optimization analysis.

[0072] It should be noted that the method in this embodiment can be executed by a single device, such as a computer or server. The method can also be applied in a distributed scenario, where multiple devices cooperate to complete the task. In such a distributed scenario, one of these devices may execute only one or more steps of the method in this embodiment, and the multiple devices will interact with each other to complete the method described.

[0073] It should be noted that the above description describes some embodiments of this application. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recorded in the claims can be performed in a different order than that shown in the above embodiments and still achieve the desired result. Furthermore, the processes depicted in the drawings do not necessarily require a specific or sequential order to achieve the desired result. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.

[0074] Based on the same inventive concept, corresponding to any of the above embodiments, this application also provides a power distribution device for a distribution radio station.

[0075] refer to Figure 3 The power distribution device of the power distribution area includes: The first acquisition module 10 is configured to acquire the structural information, first current voltage information and first current load information corresponding to each working node in the distribution radio area.

[0076] Based on the structural information, the first current voltage information, and the first current load information corresponding to each working node, multiple rounds of power allocation operations are performed. Each round of power allocation operations is executed as follows: The first determining module 201 is configured to, in response to determining that the distribution radio area is in a working state, determine the priority of each working node based on the structural information corresponding to the working node and the first current voltage information.

[0077] The second determining module 30 is configured to determine the power allocation scheme for each working node based on the first current voltage information and the first current load information corresponding to each working node.

[0078] The first allocation module 40 is configured to allocate power to each working node based on the power allocation scheme and priority corresponding to each working node. The second acquisition module 50 is configured to acquire the second current voltage information and the second current load information corresponding to each working node after a predetermined time, and use the second current voltage information and the second current load information corresponding to each working node as the first current voltage information and the first current load information in the next round of power allocation operation, and execute the next round of power allocation operation.

[0079] The first determining module 202 is further configured to exit at least one round of power allocation operation in response to determining that the distribution radio area is not in the working state.

[0080] Using the aforementioned device, structural information, first current voltage information, and first current load information corresponding to each working node in the distribution transformer area are acquired. Based on the structural information, first current voltage information, and first current load information corresponding to each working node, multiple rounds of power allocation operations are performed. Each round of power allocation operation is executed as follows: In response to determining that the distribution transformer area is in a working state, for each working node, based on the structural information and first current voltage information corresponding to the working node, the priority of the working node is determined to achieve the purpose of accurately quantifying the impact of each working node on the overall system stability. Based on the first current voltage information and first current load information corresponding to each working node, a power allocation scheme corresponding to each working node is determined. By accurately quantifying the power gap of each working node, a differentiated allocation strategy that avoids overload risks and improves energy utilization efficiency is formulated. Based on the power allocation scheme and priority corresponding to each working node, power is allocated to each working node to ensure that high-priority working nodes can work stably, thereby ensuring the stability of the system. After a predetermined time, the second current voltage information and the second current load information corresponding to each working node are obtained. These two information are then used as the first current voltage information and the first current load information in the next round of power allocation operation. This process enables dynamic power allocation, ensuring its rationality. In response to determining that the distribution area is not in the operating state, at least one round of power allocation operation is exited, ensuring closed-loop execution of dynamic power allocation.

The second allocation module is configured to, before acquiring the second current voltage information and the second current load information corresponding to each working node after a predetermined time, in response to determining that at least one bottleneck working node has experienced a communication interruption, acquire interruption data, and perform power allocation to the at least one bottleneck working node based on the interruption data; acquire the third current voltage information corresponding to each working node, and calculate the voltage qualification rate corresponding to the distribution area based on the third current voltage information corresponding to each working node; in response to determining that the voltage qualification rate is greater than a predetermined value, acquire the third current load information corresponding to each working node; and perform power allocation to each working node based on the third current load information corresponding to each working node.

[0083] In some embodiments, the first determining module 201 is further configured to, for each working node, in response to determining that the structural information corresponding to the working node is that the working node belongs to a chain topology containing a first number of working nodes, calculate a voltage drop value corresponding to the working node based on the first current voltage information; determine the priority of the working node based on the chain topology, the first number, and the voltage drop value; in response to determining that the structural information corresponding to the working node is that the working node belongs to a ring topology containing a second number of working nodes, calculate a voltage deviation value corresponding to the working node based on the first current voltage information; determine the priority of the working node based on the ring topology, the second number, and the voltage deviation value; in response to determining that the structural information corresponding to the working node is that the working node belongs to a hybrid topology containing a third number of working nodes, calculate a voltage deviation value corresponding to the working node based on the first current voltage information; determine the priority of the working node based on the hybrid topology, the third number, and the voltage deviation value.

[0084] In some embodiments, the second determining module 30 is further configured to, for each working node, determine adjustable load information corresponding to the working node based on the first current voltage information and the first current load information corresponding to the working node; and determine the working node as the bottleneck working node in response to determining that the difference between the first current load information and the adjustable load information is less than a predetermined difference.

[0085] In some embodiments, the first allocation module 40 is further configured to sort each bottleneck working node in descending order of priority based on the priority corresponding to each bottleneck working node, to obtain a sequence containing multiple bottleneck working nodes, and to allocate power to each bottleneck working node in the sequence in sequence according to the first predetermined power in the first power allocation scheme; and to allocate power to the other working nodes according to the second predetermined power in the second power allocation scheme.

[0086] In some embodiments, an adjustment module is further included. The adjustment module is configured to, before acquiring the second current voltage information and the second current load information corresponding to each working node, acquire the priority of all tasks to be executed in the bottleneck working node for each bottleneck working node, and adjust the order of all tasks to be executed based on the priority of all tasks to be executed.
