Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent regulation and control of power distribution networks, and in particular to a method and device for dynamic matching and balancing of charging load in existing distribution areas, and a medium. BACKGROUND

[0002] With the widespread popularity of new energy vehicles, the charging load in the distribution area has increased significantly, showing characteristics such as concentrated access, periodical surge and frequent power fluctuation. Since most of the existing distribution areas do not fully consider the large-scale electric vehicle charging demand during the planning and construction stage, their line structure and transformer capacity are difficult to meet the rapidly changing power demand, leading to uneven load distribution between different phases, which easily causes three-phase imbalance, voltage fluctuation and line overload, etc., affecting the safe and stable operation of the power distribution network.

[0003] Therefore, existing research has proposed an adaptive power control method based on the cooperation of electric vehicles and microgrids, which dynamically adjusts the charging power by real-time monitoring of the operating state of each charging node and combining the power output characteristics of the microgrid distributed power source, achieving load balancing and voltage stability. This method can improve the load distribution of the existing distribution area to a certain extent, and improve the voltage quality and equipment operation efficiency.

[0004] However, in actual operation, the implementation of adaptive power control highly depends on real-time communication and coordinated regulation between nodes. Due to factors such as communication network bandwidth, data transmission delay and asynchronous response of nodes, there is a time lag in the execution of some control instructions, and when multiple nodes simultaneously adjust power or correct voltage, it is easy to cause the calculation of instructions based on outdated state quantities, thereby causing secondary voltage oscillation phenomenon.

[0005] Specifically, the voltage in the distribution area repeatedly rises and falls in a short period of time, forming a periodic fluctuation; the power flow direction is impacted in the opposite direction, causing an increase in the thermal load of the transformer and line; the adjustment actions of different nodes cancel each other out or amplify, destroying the convergence of the overall dynamic matching. These phenomena not only affect the voltage stability of the system, but also reduce the accuracy of dynamic power distribution and the reliability of system response.

[0006] Therefore, the existing dynamic matching and balancing method for charging load in the existing distribution area, although it alleviates the three-phase imbalance problem to a certain extent after introducing adaptive power control of electric vehicles and microgrids, still has adverse effects on voltage stability, power flow balance and operation safety of the distribution area due to the existence of real-time communication delay and node coordination difficulties.

[0020] Referring to Figure 1 It is a flowchart of the inventory area charging load dynamic matching and balancing method provided by an embodiment of the present application.As described in the embodiment, the inventory area charging load dynamic matching and balancing method includes: S1, obtain the topology information and communication delay parameter of inventory area, and divide the inventory area into several local control subareas according to the topology information.

[0021] In the embodiment of the present application, inventory area is an existing power distribution area or network area, which is usually an area that has been put into use and has a certain scale.Topology information is the connection relationship and structure information between each power facility in inventory area, including the layout and connection mode of elements such as line, transformer and switch.Communication delay parameter is the time delay required when information is transmitted between different nodes in inventory area.

[0022] The local control sub-area is an electric power sub-area controlled independently in each area after being divided according to the topology information, and can be locally adjusted and controlled according to actual needs.

[0023] In detail, the inventory transformer area is divided into several local control sub-areas according to the topology information, including: The transformer position, feeder topology and node load distribution in the topology information are extracted. A transformer node set is obtained according to the transformer position, and a node and branch topology graph is constructed according to the transformer node set and the feeder topology. Each transformer node in the transformer node set is taken as a root node, and the topology distance between the root node and each downstream node is calculated according to the node and branch topology graph. The inventory transformer area is divided according to the node load distribution and the topology distance, and several local control sub-areas are obtained.

[0024] In the embodiment of the application, the position distribution of distribution transformers (transformers), the connection structure of feeders, and the load data of each node are obtained from the overall topology information of the inventory transformer area. The transformer position determines the power distribution point, the feeder topology provides the path of current flow, and the node load distribution gives the demand and power characteristics of power on each node.

[0025] In the embodiment of the application, the transformer node set is determined by the transformer position, which is equivalent to finding the node positions where all transformers are located. These transformer node sets are combined with the feeder topology to further establish a connection relationship graph between nodes and branches, and the branch is a line connecting different nodes. The role of the topology graph is to clearly define the physical connection path between nodes.

[0026] Further, after the node and branch topology graph is constructed, each transformer node is selected as a root node, and the topology distance between each root node and its downstream node is calculated through the connection relationship in the node and branch topology graph. The topology distance is the number of branches or power lines that need to be passed through from the root node to the downstream node, which is usually represented by the shortest path or path length.

[0027] In the embodiment of the application, the area of the transformer area is divided according to the load distribution of each node and the topology distance between nodes. The node load distribution reflects the power demand intensity of each area, and the topology distance affects the control coupling degree between areas. By combining these two data, the transformer area can be effectively divided into multiple local control sub-areas, and the power demand and load change in each sub-area can be optimized and adjusted through local control.

[0028] The present application can make the system realize more accurate regional management in physical structure and communication conditions by obtaining the topology information and communication delay parameters of the inventory substation and dividing the substation into multiple local control sub-areas according to the topology structure, which can not only shorten the communication path in the region and reduce the control error caused by delay, but also enable each sub-area to respond independently and quickly according to its own load characteristics and node distribution, thereby reducing voltage fluctuation and control conflict caused by inconsistent coordination between different regions.

[0029] S2, constructing a low-delay communication link of each of the local control sub-areas according to the communication delay parameters, and calculating the average communication delay of the low-delay communication link.

[0030] In the embodiment of the present application, the low-delay communication link is a high-efficiency information transmission path established in the local control sub-area, which is characterized by fast information transmission speed and small delay, and is used to ensure the timely exchange of control commands and state data.

[0031] The average communication delay is an average value obtained by statistically calculating the actual transmission delay of each link in the low-delay communication link, which is used to evaluate the transmission efficiency and response time of the communication link as a whole.

[0032] In detail, the step of constructing a low-delay communication link of each of the local control sub-areas according to the communication delay parameters, and calculating the average communication delay of the low-delay communication link, comprises: obtaining the point-to-point communication delay between each communication monitoring node in the inventory substation according to the communication delay parameters; constructing a node communication delay matrix according to the point-to-point communication delay; selecting the communication monitoring nodes corresponding to the point-to-point communication delay less than the preset low-delay threshold from the node communication delay matrix; generating a low-delay candidate link set according to the selected communication monitoring nodes; obtaining the topology constraints of each of the local control sub-areas, and selecting a low-delay communication link from the low-delay candidate link set by using the topology constraints; averaging all the point-to-point communication delays in the low-delay communication link to obtain the average communication delay.

[0033] In the embodiment of the present application, the delay data of each communication monitoring node in the substation is used to measure the communication delay between each pair of nodes. The delay between each pair of nodes reflects the time required for information to be transmitted from one node to another, which is usually affected by factors such as physical distance, transmission medium and network state.

[0034] Further, all the obtained point-to-point communication delay data are arranged in a matrix form. Each row and each column in the node communication delay matrix represents a communication monitoring node, and each element in the matrix represents a communication delay value between two nodes. The node communication delay matrix is a symmetric matrix, which can intuitively show the delay relationship of communication between nodes.

[0035] In the embodiment of the present application, according to a preset low-delay threshold, node pairs with a communication delay less than the threshold are screened from the node communication delay matrix. Through this screening operation, node pairs with a faster response speed can be found, which are used as candidate nodes for establishing a low-delay communication link.

[0036] Further, on the basis of the screened node pairs, a low-delay candidate link set is generated. This set contains all node pairs with a communication delay less than the preset threshold, indicating that the communication links between these nodes can be regarded as low-delay links, which have a faster response time and are suitable for efficient information exchange.

[0037] In the embodiment of the present application, by obtaining the topology constraints of each local control sub-area, considering the power network structure in each node communication delay matrix, the connection relationship between nodes and other factors, links that meet the topology constraint conditions are further screened from the low-delay candidate link set, so as to ensure that the selected low-delay communication links have both low delay and meet the topology requirements of the power network in the local control sub-area.

[0038] In the embodiment of the present application, after the low-delay communication links that meet the topology constraints are selected, the average of all point-to-point communication delays in these links is calculated to obtain an overall average communication delay value. The average communication delay value represents the overall performance of the low-delay links, helps to evaluate the average response time of information transmission in the network, and further optimizes the control efficiency of the entire substation.

[0039] The present application can significantly improve the speed and efficiency of information transmission between sub-areas by constructing low-delay communication links for each local control sub-area according to the communication delay parameters and calculating the average communication delay of the low-delay communication links. The low-delay communication links ensure that control signals and data can be quickly exchanged between sub-areas, thereby reducing the response time lag and coordination inconsistency problems caused by delay. This efficient communication mechanism enables each local control sub-area to respond more quickly to changes in power load, avoiding voltage fluctuations and power imbalance problems caused by excessive delay in the system. The calculation of the average communication delay further helps to optimize the network performance, ensuring the stability and efficiency of the entire substation under dynamic load changes, and improving the real-time response capability and control accuracy of the system.

[0040] S3, delay compensating the voltage sampling sequence and the charging load power sequence of the local control sub-area according to the average communication delay, to obtain voltage trend information and load power trend information.

[0041] In the embodiments of the present application, the voltage sampling sequence is a data sequence obtained by sampling the voltage signal in the local control sub-area within a certain time period, and is usually used to analyze the change trend of the voltage. The charging load power sequence is a data sequence obtained by sampling the power of the charging load in the local control sub-area within a certain time period, and is used to analyze the change of the load power. The delay compensation is to adjust the time sequence of the voltage and load power data according to the time difference of the communication delay, so as to reflect the real load and voltage state and eliminate the influence caused by the transmission delay.

[0042] The voltage trend information is trend information obtained by analyzing the voltage sampling sequence, and reflects the change direction and amplitude of the voltage within a certain time. The load power trend information is trend information obtained by analyzing the charging load power sequence, and reflects the change direction and amplitude of the load power within a certain time.

[0043] In detail, the delay compensating the voltage sampling sequence and the charging load power sequence of the local control sub-area according to the average communication delay, to obtain voltage trend information and load power trend information, comprises: obtaining the voltage sampling sequence and the charging load power sequence of each communication monitoring node in the local control sub-area; calculating a voltage delay difference component according to two adjacent voltage data in the voltage sampling sequence; calculating a power delay difference component according to two adjacent charging load power data in the charging load power sequence; performing trend analysis on the voltage and the charging load power of the communication monitoring node respectively by using a preset delay compensation parameter according to the voltage delay difference component and the power delay difference component, to obtain voltage trend information and load power trend information.

[0044] In the embodiments of the present application, real-time sampling data of voltage and charging load power are collected from each communication monitoring node. The voltage sampling sequence represents the record of the change of the voltage value with time, and the charging load power sequence records the real-time fluctuation data of the charging load power. These data are the basis for subsequent analysis and compensation, and help to understand the voltage state and load change of the node.

[0045] Further, the voltage delay difference component is obtained by calculating the difference between two adjacent voltage data points in the voltage sampling sequence. The voltage delay difference component reflects the change amount within the voltage data sampling interval due to factors such as communication delay, and is used to quantify the influence of delay on the change of voltage.

[0046] Furthermore, the power delay difference component is obtained based on the difference between two adjacent power data points in the charging load power sequence. The power delay difference component reflects the delay in load power changes caused by communication delays or other factors, which helps in analyzing the response delay during load power regulation.

[0047] In this embodiment of the invention, the voltage difference component and the power difference component are used as inputs. Compensation parameters are applied to smooth, weight, or offset these components, reflecting the true changing trends under the influence of communication delay. Through this analysis process, each communication monitoring node obtains voltage trend and load power trend values, which characterize the dynamic direction and magnitude of voltage and power changes after delay compensation. The calculation formulas are as follows:

[0048]

[0049] in, This represents the voltage trend of the i-th communication monitoring node at time t. Indicates the first The voltage sampling sequence of the i-th communication monitoring node at time i. Indicates average communication delay. Indicates the delay compensation parameter. This represents the voltage delay difference component of the i-th communication monitoring node. This represents the load power trend of the i-th communication monitoring node at time t. Indicates the first The charging load power sequence of the i-th communication monitoring node at time i. This represents the power delay difference component of the i-th communication monitoring node.

[0050] This invention compensates for the delay in the voltage sampling sequence and charging load power sequence of a local control sub-region based on the average communication delay. This effectively reduces the impact of communication delay on data acquisition and control response, making the trend analysis of voltage and load power more accurate. The voltage and load power trends after delay compensation can truly reflect the dynamic state of the system, enabling the local control sub-region to adjust the load distribution and voltage level in a timely and accurate manner. This avoids voltage fluctuations and power backlashes caused by information lag, improving control accuracy and response speed, and providing a reliable data foundation for global coordinated control. Consequently, it enhances stability and adaptability under complex load changes.

[0051] S4. Dynamically match and adjust the local control sub-region according to the voltage trend and the load power trend to obtain the average voltage trend and power distribution data for each control cycle.

[0052] In this embodiment of the invention, dynamic matching adjustment is a process of keeping the voltage and load power coordinated and optimized during real-time adjustment based on the voltage trend and the load power trend.

[0053] A control cycle is the time period during which control is performed in a power system. It is typically a fixed time period used to adjust voltage and load power. The average voltage trend value is the value obtained by averaging voltage trend values ​​within a control cycle, reflecting the overall trend of voltage changes during that cycle. Power distribution data describes the distribution of charging load power among nodes or sub-regions within each control cycle, usually expressed as the load power value or proportion of each node.

[0054] In detail, the step of dynamically matching and adjusting the local control sub-region based on the voltage trend and the load power trend to obtain the average voltage trend and power distribution data for each control cycle includes: Obtain the voltage reference value for each of the local control sub-regions, and calculate the voltage deviation by subtracting the voltage reference value from the voltage trend value. The load power deviation is generated based on the change in the load power trend. The dynamic adjustment amount for each local control sub-region is generated based on the voltage deviation and the load power deviation; The power between nodes in the local control sub-region is quickly corrected using the dynamic adjustment amount to obtain the corrected load power. The voltage sampling sequence of the local control sub-region is periodically and dynamically adjusted using the corrected load power to obtain the voltage regulation state; Calculate the average voltage trend value for each control cycle based on the voltage regulation state; Power distribution data is generated based on the corrected load power.

[0055] In this embodiment of the invention, the ideal or target voltage value, i.e., the voltage reference value, is obtained from historical data for each local control sub-region. The actual measured voltage trend is compared with the voltage reference value, and the voltage deviation is obtained by calculating the difference between the two. The voltage deviation reflects the degree of deviation of the current voltage from the target value.

[0056] In this embodiment of the invention, by analyzing the changes in load power trend within the current control cycle, the power difference deviating from the expected or target state, i.e., the load power deviation, is calculated, which reflects the deviation in the rate and magnitude of load power change and provides a quantitative indicator for load adjustment.

[0057] Further, the voltage deviation and the load power deviation are integrated to generate a dynamic adjustment amount according to a preset adjustment rule or weight. The adjustment amount is an overall regulation instruction for each local control sub-area, indicating how to adjust the node voltage and the load power to reduce the deviation and achieve coordination of the voltage and the power, and the calculation formula is as follows:

[0058] wherein, denotes the dynamic adjustment amount of the i th communication monitoring node, denotes the voltage adjustment weight, denotes the voltage deviation of the i th communication monitoring node, denotes the power adjustment weight, denotes the load power deviation of the i th communication monitoring node.

[0059] In the embodiment of the present application, the power between the communication monitoring nodes in the local control sub-area is adjusted according to the dynamic adjustment amount. Through rapid correction, the load power is redistributed to be closer to the target value, so that the corrected load power data is obtained to provide a basis for voltage adjustment.

[0060] Further, the corrected load power is applied to the voltage sampling sequence, and the voltage is dynamically adjusted according to the control period to observe and record the voltage change of each communication monitoring node. Through this operation, the current voltage adjustment state can be obtained to reflect the change effect of the node voltage after power correction.

[0061] In the embodiment of the present application, after the voltage adjustment is completed, the voltage trend amount of each communication monitoring node in the control period is averaged to obtain the voltage trend amount mean value. The mean value reflects the overall trend of the voltage change in the entire control period.

[0062] Further, the corrected load power data is sorted into power distribution information to describe the distribution of the load power in each node or sub-area. The power distribution data is used to evaluate the load adjustment effect and provide basic data for subsequent global coordination control and load management.

[0063] The present application can accurately control the voltage and the load power in each control period by dynamically matching and adjusting the local control sub-area according to the voltage trend amount and the load power trend amount. This dynamic adjustment method not only can reflect the change trend of the voltage and the power in real time, but also can effectively reduce the influence of power fluctuation and imbalance, and ensure the stable operation of the system under complex load changes. By calculating the voltage trend amount mean value and the power distribution data, the overall trend of the voltage change and the distribution of the load power can be more clearly mastered.

[0064] S5, globally asynchronously coordinating control the local control subareas according to the voltage trend quantity mean value and the power distribution data, to obtain an updated voltage and a load power adjustment distribution.

[0065] In the embodiment of the present application, the globally asynchronous coordination control is a non-synchronous coordination between multiple local control subareas in a global range, so as to realize the balance and optimization of the voltage and the load power of the whole system.

[0066] The updated voltage is an adjusted voltage value after the global coordination control, which reflects the new state after the voltage adjustment, and ensures that the voltage of the system meets the preset target. The load power adjustment distribution is a new distribution of the load power between different nodes or subareas after the global coordination adjustment, which is used to optimize the load matching of the power system.

[0067] In detail, the globally asynchronously coordinating control the local control subareas according to the voltage trend quantity mean value and the power distribution data, to obtain an updated voltage and a load power adjustment distribution, comprises: The voltage trend quantity mean value of each local control subarea and the power distribution data are summarized as subarea global state data; According to the subarea global state data of each local control subarea and the adjacent local control subarea, a cross-subarea voltage difference value is obtained by voltage difference analysis; According to the power distribution data, a load power distribution deviation is obtained by weighted difference calculation of the load power distribution of the local control subarea; The cross-subarea voltage difference value and the load power distribution deviation are respectively subjected to asynchronous iteration coordination, to obtain an updated voltage and a load power adjustment distribution.

[0068] In the embodiment of the present application, the voltage trend quantity mean value and the power distribution data of each local control subarea are summarized to form the global state data of each subarea. These global state data include the overall voltage change trend and the load power distribution, which can comprehensively reflect the running state of each local control subarea.

[0069] Further, by comparing the voltage trend quantity mean value in the global state data of each local control subarea and its adjacent subarea, the voltage difference value between the two subareas is calculated, which reflects the deviation and imbalance existing in the voltage adjustment process of each local control subarea.

[0070] In the embodiment of the present application, according to the power distribution data of each local control subarea, the weighted difference value calculation is performed on the distribution of the load power between nodes, and the deviation of the load power is obtained by assigning weights to different nodes or regions, which reflects the imbalance and adjustment demand of the system in the load distribution.

[0071] Further, by the asynchronous iteration coordination method, the cross-subarea voltage difference and the load power distribution deviation are adjusted. The coordination of voltage difference aims to narrow the voltage gap between each subarea, and the coordination of load power distribution deviation ensures the more balanced distribution of power between different areas. Through such coordination adjustment, the updated voltage and load power distribution are finally obtained, making the system more stable and coordinated, and the calculation formula is as shown below:

[0072]

[0073] wherein, denotes the updated voltage of the mth local control subarea in the a+1th iteration, denotes the voltage of the mth local control subarea in the ath iteration, denotes the voltage iteration gain parameter, denotes the set of adjacent local control subareas, denotes the cross-subarea voltage difference between the mth local control subarea and the nth local control subarea, denotes the load power adjustment distribution of the mth local control subarea in the a+1th iteration, denotes the load power of the mth local control subarea in the ath iteration, denotes the load power iteration gain parameter, denotes the load power distribution deviation between the mth local control subarea and the nth local control subarea.

[0074] By using the voltage trend quantity mean value and the power distribution data to perform global asynchronous coordination control on the local control subareas, the application can ensure the independent adjustment ability of each subarea while realizing the coordinated optimization of the whole system. This control method can effectively reduce the voltage difference and power distribution imbalance between different subareas, and make the updated voltage and load power adjustment distribution more stable and reasonable. Through asynchronous coordination, the system can complete the dynamic adjustment across subareas without relying on strict synchronous operation, improving the flexibility and response speed of the control. At the same time, this method enhances the stability and adaptability of the power system under complex load fluctuations and sudden events, ensuring that the voltage level and load distribution of the whole area maintain in the optimized state.

[0075] S6, oscillation detection and damping control are performed on the updated voltage, and a global dynamic balance state of the inventory area is generated according to the control voltage obtained by control and the load power adjustment distribution.

[0076] In the embodiments of the present application, the oscillation detection is to monitor and analyze the updated voltage signal to identify the periodic or non-periodic fluctuation phenomenon of the voltage over time, for judging whether the system has unstable oscillation. The damping control is a control process of adjusting the voltage or load power control strategy to weaken or eliminate the detected voltage oscillation, so as to make the voltage tend to be stable.

[0077] The control voltage is the voltage value adjusted by the oscillation detection and damping control, which is used to maintain the stability of the power grid and match the load. The global dynamic balance state is the operation state in which the voltage and power in the entire inventory area reach a coordinated and stable state under the action of oscillation detection, damping control and load power adjustment, and the whole maintains dynamic balance.

[0078] In detail, the oscillation detection and damping control of the updated voltage and the generation of the global dynamic balance state of the inventory area according to the control voltage obtained by control and the load power adjustment distribution include: Obtain the historical voltage of the last control period, and calculate the voltage change rate of each communication monitoring node according to the historical voltage and the updated voltage; Perform fast Fourier transform on the voltage change rate to obtain a frequency domain result; Identify the voltage oscillation frequency in the frequency domain result; When the voltage oscillation frequency is greater than a preset frequency threshold, the communication monitoring node triggering damping compensation is taken as a trigger node; Perform damping compensation control on the trigger node to obtain a damping compensation amount; Fuse the damping compensation amount and the load power adjustment distribution to obtain the global dynamic balance state of the inventory area.

[0079] In the embodiments of the present application, the voltage data of the last control period is extracted as the historical voltage, which is compared with the current updated voltage. By calculating the change amount between the historical voltage and the updated voltage within a certain time, the voltage change rate of each communication monitoring node can be obtained, which describes the change speed and amplitude of the voltage within a control period.

[0080] Further, the voltage change rate data is subjected to fast Fourier transform (FFT), so as to convert the voltage change in the time domain into a signal in the frequency domain, thereby helping to identify the periodic characteristics of the voltage change. FFT can reveal different frequency components contained in the voltage change, which is helpful for analyzing the frequency characteristics of the voltage fluctuation. In the frequency domain result, the main frequency of the voltage oscillation is identified. The voltage oscillation frequency is the main periodic component of the voltage fluctuation, which is usually a symbol of unstable power system or oscillation. By analyzing the FFT result, the component with the highest frequency can be found, so as to determine the frequency of the oscillation.

[0081] In the embodiment of the present application, if the voltage oscillation frequency exceeds the frequency threshold, it indicates that there is unstable oscillation phenomenon of the voltage. The communication monitoring nodes that will have large oscillation are regarded as trigger nodes, which are the objects of damping compensation. The trigger nodes are determined according to the oscillation frequency, and are the focus of damping compensation control.

[0082] Further, the operation of damping compensation control on the trigger nodes is to slow down or eliminate the influence of voltage oscillation by adjusting the node voltage or load power. The damping compensation amount refers to the control amount required to balance the voltage fluctuation, and its purpose is to reduce the amplitude of voltage fluctuation and restore the system to stability, and the calculation formula is as follows:

[0083] Wherein, represents the damping compensation amount of the i th communication monitoring node, represents the damping control coefficient, represents the voltage change rate of the i th communication monitoring node.

[0084] In the embodiment of the present application, the obtained damping compensation amount is combined with the load power adjustment distribution, and the adjusted voltage and load power are fused to form a global dynamic balance state. This state ensures the coordination of system voltage and load power, achieves the goal of stable operation, so that the substation can maintain balance when disturbed or load fluctuates.

[0085] The present application can detect and suppress possible voltage oscillation in time through oscillation detection and damping control of the updated voltage, avoid the unstable influence of voltage fluctuation on the operation of the substation. Combined with the load power adjustment distribution, a global dynamic balance state is formed, so that the voltage and power are coordinated and consistent in the entire inventory substation, which improves the stability of the system under load fluctuation and sudden events. Not only can effectively reduce voltage oscillation and power impact, but also can ensure the reliability of the power system in fast response and continuous operation, improve the overall regulation accuracy and operation safety.
