Finally, when the target terminal access device is successfully connected to the initial distribution network, according to the topology identification strategy, the target distribution network is generated into an application architecture corresponding to the target distribution network. Considering that after obtaining the first parameter information of the target terminal access device in the initial distribution network, the target terminal access device can be controlled to access the initial distribution network according to the first parameter information to obtain the target distribution network, and then according to the topology identification strategy, an application architecture corresponding to the obtained target distribution network is generated.

[0047] Optionally, based on the evaluation information and using the hierarchical analysis method, a hierarchical structure for evaluating the importance of edge terminal device access is constructed, and based on the hierarchical structure, the data contained in each structure is processed to achieve the purpose of determining the target terminal access device.

As long as the process and method for determining the target terminal access device are based on the evaluation information of the target terminal access device obtained, they are within the scope of protection of the present invention and are not listed here.

[0049] As an optional implementation method, multiple information division layers include at least: a target layer and an intermediate layer, wherein the target layer is used to characterize the importance of the target terminal access device, and the intermediate layer is used to characterize the business information in the initial distribution network. Based on the multiple information division layers, the target terminal access device is determined, including: obtaining multiple first indicator weights of the target layer and multiple second indicator weights of the intermediate layer; generating a judgment matrix of the initial distribution network based on the multiple first indicator weights and the multiple second indicator weights; based on the verification condition of the judgment matrix, verifying the judgment matrix to obtain a verification result, wherein the verification result is used to characterize that the judgment matrix satisfies the verification condition; in response to the verification result, based on the objective function of the judgment matrix, the target terminal access device is determined, wherein the objective function is a function with the root mean square value in the judgment matrix as the constraint target.

First, multiple first indicator weights of the target layer and multiple second indicator weights of the intermediate layer can be obtained, and then the judgment matrix of the initial distribution network is generated according to the multiple first indicator weights and multiple second indicator weights obtained above. Then, according to the verification conditions of the judgment matrix, the judgment matrix is ​​verified to obtain the verification result. Finally, according to the verification result and the objective function of the judgment matrix, the purpose of determining the target terminal access device is achieved.

R<0.1, it means that the judgment matrix A generated at this time meets the consistency requirements; for the judgment matrix that does not meet the consistency check, it is necessary to adjust the measurement indicators until the consistency check conditions are met.

[0059] Optionally, the objective function is a function that takes the minimum root mean square value in the judgment matrix as a constraint target. For example, taking the minimum root mean square value of the adjustment range of the elements in the judgment matrix A as the target, the adjustment problem of the matrix A is modeled as a constrained optimization problem using the following formula:

Among them, the target area can be a preset low-voltage side area. The target user can be referred to as a user.

[0072] Optionally, in accordance with the topology identification strategy, the process of generating the target distribution network application architecture from the target distribution network is as follows: using the power line as the communication carrier, based on the industrial frequency distortion communication technology, a communication channel is established between the low-voltage smart meter and the low-voltage transformer, the terminal area identification application sends the signal identified by the monitoring terminal broadcast area to the branch box of the transformer; the branch box distribution network monitoring terminal actively reports the registration information to the edge side terminal, and the edge side terminal stores the information locally; the edge side terminal sends a pulse voltage signal in a polling manner, and then the edge side terminal collects the voltage signal of the distribution network monitoring terminal of each branch box through broadband carrier technology; the edge side terminal executes the topology identification algorithm to realize the identification of the topological relationship in the distribution network step by step.

[0096] With the rapid development of new energy equipment, energy storage equipment and electric vehicles, as well as the deepening of power system reform, the distributed resources of the distribution network are not only energy consumers, but also participants in energy production, management and trading. However, the application of distributed resources in the distribution network, especially the flexible and adjustable resources on electric vehicles or distributed photovoltaic equipment, has a small amount of data, making it difficult for traditional power grids to store and process this data in a timely and effective manner, and the data in the distributed resources of the distribution network is usually relatively isolated in the data flow.

[0104] Optionally, on the device side, the relevant equipment is installed on various electrical equipment such as distributed photovoltaic equipment, electric vehicle charging piles, distributed energy storage equipment, etc., and the above-mentioned equipment is used to collect power data and upload it to the edge through the local communication network.

[0105] Optionally, the user layer based on artificial intelligence technology can optimize the scheduling of local communication, computing and other resources, and install the local model to the cloud to provide a basis for synchronous data processing. At the same time, data encryption technology realizes secure terminal access and data transmission.

[0106] Step S202, construct a bidirectional business flow of distributed resources in the distribution network based on cloud-edge integration.

[0107] In this embodiment, a bidirectional business flow of distributed resources in the distribution network based on cloud-edge integration can be constructed, and the above bidirectional business flow is implemented through two strategies: a bottom-up distributed resource regulation strategy and a top-down distributed resource regulation strategy.

[0108] Optionally, the process of the bottom-up distributed resource regulation strategy is as follows: the device on the user side collects distributed photovoltaic data, charging pile data, distributed energy storage and other user data in the local control center and uploads them to the edge side in real time. The edge node uses real-time data or historical data and the following multiple strategies to complete distributed resource regulation, where the multiple strategies include: regional distributed photovoltaic regulation strategy, regional distributed energy storage regulation strategy and regional electric vehicle orderly charging strategy; then, each edge node uploads the regional strategy and related data to the cloud center, and the cloud center further optimizes the regional strategy from multiple angles according to the power consumption conditions of each region to complete distributed energy storage regulation, distributed photovoltaic regulation and orderly charging of electric vehicles.

[0109] Optionally, the top-down distributed resource regulation strategy process is as follows: the cloud center is responsible for formulating the global control strategy, broadcasting the global control strategy to all distributed resources, and distributing the distributed energy storage devices with edge nodes as the smallest unit to each edge node according to the control strategy; the edge nodes adjust their own decisions according to the optimization results of the upper level, and finally entrust the control decisions that meet the global and regional requirements to the users; the edge nodes also obtain a variety of recommended strategies for different types of distributed resources in the region, and entrust them to the user's control center; the device end on the user side can use the strategy to form the optimal strategy for local distributed resource regulation according to its own operational constraints and regional decisions, and finally complete the local response by controlling the operating status of each device.

[0110] Step S203: Use the hierarchical analysis method to evaluate the importance of the connected edge terminal device.

[0111] In this embodiment, the hierarchical analysis method may be used to evaluate the importance of the connected edge terminal devices, so as to determine the terminal devices that need to be connected to the power distribution network.

[0112] Optionally, Figure 4 This is a schematic diagram of analyzing the importance of terminal devices using the hierarchical analysis method according to an embodiment of the present invention. As shown in the figure, the schematic diagram includes: a factor layer 401, an intermediate layer 402 and a target layer 403.

[0113] Optionally, the factor layer 401 corresponds to different types of terminals, including distribution terminals 4011, distribution transformer terminals 4012, feeder terminals 4013 and distributed new energy terminals 4014; the middle layer 402 corresponds to different businesses in the distribution objects, including electricity consumption information collection business module 4021, production management business module 4022, environmental monitoring business module 4023, relay protection business module 4024, distribution automation business module 4025 and distributed system control module 4026; the target layer 403 includes an underlying terminal importance determination module 4031, which is used to determine the importance of the terminal, arrange them in descending order according to the importance, and ensure the access of target terminals with high importance to access devices.

[0114] Optionally, the process of evaluating the importance of edge terminal device access using the hierarchical analysis method is as follows: determine the weight of each indicator, use a measurement tool (reciprocal 1-9 scale) to compare the importance of each element of the intermediate layer and the target layer, obtain multiple comparison results, and mark the comparison results as a ij , and let A=[a ij ] is the judgment matrix of this layer; consistency check, using the following formula for consistency check: that is:

[0115]

[0116] In the above formula, λ max It is used to represent the maximum eigenvalue of matrix A; n is used to represent the order of matrix A; R 1 The index used to represent the average random consistency is obtained by randomly constructing the judgment matrix A and calculating it as follows:

[0117]

[0118] In the above formula, K is used to represent the number of constructed random judgment matrices. R <0.1, it means that the judgment matrix A generated at this time meets the consistency requirements; for the judgment matrix that does not meet the consistency check, it is necessary to adjust the measurement indicators until the consistency check conditions are met.

[0119] Furthermore, after the consistency check is performed, overall modeling is required: with the goal of determining the minimum root mean square value of the adjustment amplitude of the elements in matrix A, the adjustment problem of matrix A is modeled as a constrained optimization problem using the following formula:

[0120]

[0121] In the above formula, a ij and a' ij They are used to represent the values ​​of the elements before and after the adjustment respectively; a ij and They are used to represent the minimum and maximum values ​​of the element's index.

[0122] Furthermore, after performing the overall modeling, it is necessary to determine the importance of the terminal equipment: Let [δ l1， δ l2 ,....,δ ln ] T The eigenvector corresponding to the maximum eigenvalue of the judgment matrix of the lth distribution network business in the middle layer determined by the factor layer; [Δ 1 , Δ 2 ,...,Δ n ] T is the eigenvector corresponding to the maximum eigenvalue of the judgment matrix of the target layer determined by the intermediate layer, then the importance of the terminal node k is defined as:

[0123]

[0124] In the above formula, M k It is used to indicate the importance of the terminal. The importance value is used to sort multiple edge-side intelligent converged terminals in descending order, and the number of terminals allowed to access is determined based on their own carrying capacity.

[0125] Step S204: adopting an automatic registration method to achieve instant access of the edge terminal device.

[0126] In this embodiment, after the importance of the edge terminal device is determined, an automatic registration method may be used to achieve instant access to the edge terminal device. Figure 5 is a flow chart of a method for active registration of a terminal device according to an embodiment of the present invention. Figure 5 As shown, the main steps of the method are as follows:

[0127] Step S501, input the unique identifier of the device.

[0128] In this embodiment, after the wiring is installed in the power distribution network, the unique identifier PMS_ID of the device is entered.

[0129] Step S502, according to the unique identifier of the device, a mapping process is performed using the model to obtain a mapping list.

[0130] In this embodiment, mapping processing is performed using a model according to a unique identifier of the device to achieve the purpose of obtaining a mapping list, wherein the mapping list can be a failure list and a success list.

[0131] Step S503: Generate a target file based on the mapping list.

[0132] In this embodiment, a target file may be generated according to the obtained mapping list, wherein the target file may be an ICD file.

[0133] Step S504, determining whether the device is mapped successfully.

[0134] In this embodiment, whether the device mapping is successful is determined based on the ICD file, and if successful, step S505 is executed; if failed, step S501 is executed.

[0135] Step S505: confirm the access device at the edge.

[0136] Step S506: confirm the access device at the device end.

[0137] In this embodiment, the process of using the automatic registration method to achieve instant access to the edge terminal device is as follows: after the low-voltage device is installed and the unique identifier (PMS_ID) of the device is entered, the Internet Protocol address (IP address), device type, device PMS_ID self-description information, etc. of the device are actively reported to the edge terminal, and a registration request is sent; after receiving the registration request, the edge terminal performs mapping and matching based on the PMS_ID and other information of the device, completes the model instantiation of the low-voltage device, and generates a list of secondary devices that are successfully mapped; the secondary device is instantiated by the acquisition application in the terminal to generate an ICD file;

[0138] Furthermore, the substation terminal uploads the ICD file to the cloud-side master station; the cloud-side master station checks whether all primary and secondary devices are mapped successfully, and if successful, sends confirmation information to each edge-side terminal; otherwise, the error information is pushed to the cloud-side master station, which sends an operation and maintenance work order to the operation and maintenance personnel for confirmation, and repeats the above operations until there is no list of mapping failures; after the device mapping is completed, the registration result is replied by the substation terminal and sent to the device, and the device completes instant access and starts to provide services.

[0139] Step S205, using a topology identification algorithm to perform topology identification on the distribution network connected to the edge-side intelligent terminal, obtaining a topology structure, and generating an application architecture based on the topology structure.

[0140] In this embodiment, a topology identification algorithm may be used to perform topology identification on the distribution network connected to the edge-side intelligent terminal, so as to obtain the topological structure, and then generate an application architecture based on the obtained topological structure.

[0141] Optionally, after the distribution network is connected to the edge side terminal, the process of topology identification of the distribution network at this time is: using the power line as the communication carrier, based on the industrial frequency distortion communication technology, a communication channel is established between the low-voltage smart meter and the low-voltage transformer, the terminal area identification application sends the signal identified by the monitoring terminal broadcast area to the branch box of the transformer; the branch box distribution network monitoring terminal actively reports the registration information to the edge side terminal, and the edge side terminal saves the information locally; the edge side terminal sends a pulse voltage signal in a polling manner, and then the edge side terminal collects the voltage signal of the distribution network monitoring terminal of each branch box through broadband carrier technology; the edge side terminal executes the topology identification algorithm to realize the identification of the topological relationship in the distribution network step by step.

[0142] Optionally, after the distribution network is connected to the edge terminal, the topology identification algorithm is used to perform topology identification. The execution process is as follows: by adjusting the transformer, the fluctuation amplitude of the substation voltage is changed, and the low-voltage side voltage value U′ is collected. i ={U' i (1),…,U' i (N)}, and the user side voltage value u″ j ={u″ j (1),…,u″ j (N)}; the voltage obtained above is dimensionless, as shown in the following formula:

[0143]

[0144]

[0145] In the above formula, i is used to represent the number of the transformer, j is used to represent the number of the terminal device, and k=1,2,...,N.

[0146] Further, the similarity coefficients of the voltage fluctuations on the user side and the transformer side are calculated, and the calculation method of the similarity coefficient is expressed by the following formula:

[0147]

[0148] In the above formula, σ is used to represent the resolution coefficient, which is 0.5, and Δu ij (k)=|u′ j ′(k)-U j ′(k)|. Based on the similarity coefficient, the correlation coefficient of the voltage fluctuations on the user side and the substation side is calculated, which can be expressed by the following formula:

[0149]

[0150] In the above formula, Used to represent the correlation coefficient. After the correlation coefficient is obtained, the topological relationship is identified according to the correlation. For example, if the correlation between the j-th terminal device and the i-th transformer voltage is the highest, then the terminal device is determined to belong to the i-th station area.

[0151] In this embodiment, the first parameter information of the target terminal access device in the initial distribution network can be obtained first, and then according to the first parameter information obtained above, the target terminal access device can be controlled to access the initial distribution network to achieve the purpose of obtaining the target distribution network. Finally, when the target terminal access device successfully accesses the initial distribution network, according to the topology identification strategy, the target distribution network generates an application architecture corresponding to the target distribution network. Considering that after obtaining the first parameter information of the target terminal access device in the initial distribution network, the target terminal access device can be controlled to access the initial distribution network according to the first parameter information to obtain the target distribution network, and then according to the topology identification strategy, the application architecture corresponding to the obtained target distribution network is generated. By using this application architecture, the technical problem that the distribution network cannot effectively process data in real time is solved, and the technical effect that the distribution network can effectively process data in real time is achieved.
