[0044] To make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0045] Embodiment 1, please refer to Figure 1 The adaptive optimization method for power distribution network planning described in the present embodiment includes the following steps:

[0046] S1, acquire a planning range of power distribution network planning, acquire power distribution demand information in the planning range, wherein the power distribution demand information includes a plurality of power distribution ranges and corresponding load demand, and a power distribution model is constructed based on the planning range and the power distribution demand information;

[0047] S2, respectively determine power distribution types of the plurality of power distribution ranges and mark on the power distribution model, respectively copy the plurality of power distribution ranges based on the power distribution model to obtain a plurality of backup power distribution ranges, and establish a corresponding relationship between the power distribution range and a planning library based on the power distribution type;

[0049] S4, respectively match the unit models of the plurality of power distribution ranges based on the power distribution model to obtain a plurality of power distribution network planning schemes;

[0050] S5, select an optimal power distribution network planning scheme as a target planning scheme from the plurality of power distribution network planning schemes;

[0051] As described in the above steps S1-S5, the power distribution network planning method is based on static load prediction and fixed planning framework. When facing the construction of power distribution network planning of a region, the power distribution network structure needs to be designed considering the power consumption information of each region, which consumes a lot of effort and is difficult to comprehensively give multiple power grid structure designs for the region. Therefore, it is difficult to select the optimal power grid structure. In the present application, the unit models of the plurality of backup power distribution ranges in a single combined scheme are connected in communication according to the communication relationship between the fixed points in the plurality of power distribution ranges, and the plurality of unit models are connected in parallel through a parallel grid end to obtain a power distribution network planning scheme. Multiple combined schemes obtain multiple power distribution network planning schemes, which can obtain multiple power distribution network planning schemes, provide reference for the environment of the power grid with multiple planning schemes, and ensure the comprehensiveness of the power grid selection. Then, when the power distribution structure is optimized, the optimal power distribution network planning scheme can be selected to give effective suggestions for the construction of the power distribution network.

[0052] In one embodiment, the step S1 of constructing the power distribution model based on the planning range and the power distribution demand information includes:

[0053] S11, acquire a planning range of power distribution network planning, acquire a plurality of power distribution ranges and corresponding load demand in the planning range as power distribution demand information;

[0054] S12, construct an electronic map based on the planning range, mark the power distribution demand information in the electronic map to obtain a power distribution model;

[0055] As described in steps S11 and S12, the power distribution network needs to determine the range of the power grid planning when planning, and then the multiple power distribution ranges and the corresponding load demand in the planning range as the power distribution demand information, wherein the multiple power distribution ranges are the ranges of the same type of power distribution load demand, for example, the range of a community for power distribution is taken as a power distribution range, and the range of a factory for power distribution is taken as another power distribution range, then multiple power distribution ranges are obtained according to different load demands, and then an electronic map is constructed based on the planning range, the power distribution demand information is marked in the electronic map to obtain a power distribution model, which can better understand the power distribution demand and the location, and better perform subsequent power distribution planning.

[0056] In one embodiment, the step S2 of establishing the corresponding relationship between the power distribution type and the planning library based on the power distribution model includes:

[0057] S21, determining the power distribution type of the multiple power distribution ranges, wherein the power distribution type includes data range information of the load demand, and the power distribution type is marked on the power distribution model;

[0058] S22, copying the multiple power distribution ranges in the power distribution model to obtain multiple power distribution range models as multiple backup power distribution ranges, and binding the multiple backup power distribution ranges and the corresponding power distribution ranges;

[0059] S23, setting a planning library, wherein the planning library includes a power distribution type, multiple power grid structures corresponding to the power distribution type, and attribute information corresponding to the power grid structure, and a grid-connected end is marked on the power grid structure;

[0060] S24, establishing the corresponding relationship between the power distribution type and the planning library based on the power distribution type and the multiple backup power distribution ranges;

[0061] As described in steps S21-S24, the power distribution types of the plurality of power distribution ranges are obtained, wherein the power distribution types include data range information of load demand, the power distribution types are marked on the power distribution model, for example, the loads of community power consumption and factory power consumption are different, and the corresponding data range information of load demand is also different, so the plurality of power distribution ranges are divided by different power consumption subjects, and the power consumption subjects are subjects such as communities or factories. After that, the plurality of power distribution range models are obtained by copying the plurality of power distribution ranges in the power distribution model as a plurality of standby power distribution ranges, the plurality of standby power distribution ranges are information bound with the corresponding power distribution ranges, and each power distribution range copies a plurality of power distribution range models as a plurality of standby power distribution ranges. The plurality of standby power distribution ranges are used for subsequent selection of the planning library of the power grid structure, and are used for subsequent combination of the power grid structure in the plurality of power distribution ranges, wherein the planning library is set, and the planning library includes power distribution types, a plurality of power grid structures corresponding to the power distribution types, and attribute information corresponding to the power grid structures. The grid-connected end is marked on the power grid structure. The attribute information corresponding to the power grid structure includes economic attributes, technical attributes, wherein the economic attributes include investment cost and operation cost; the technical attributes include power supply capacity, reliability and other attributes, which can adaptively select the power distribution network planning, thereby optimizing the planning of the power distribution network, and has a good effect on the planning of the power distribution network, and can understand the multiple scheme conditions of the power distribution network planning as much as possible.

[0062] In one embodiment, the step S24 of establishing the correspondence between the power distribution types and the planning library includes:

[0063] S241, a fixed point in each of the plurality of power distribution ranges in the power distribution model is selected, and the positions of the fixed points in the plurality of standby power distribution ranges in the power distribution range are obtained as follower fixed points;

[0064] S242, the communication relationship between the follower fixed points of the plurality of standby power distribution ranges and the fixed points is established to obtain a plurality of communication layers, the communication layers are fixed and coded to obtain communication layer identities;

[0065] S243, the communication relationship between the fixed points in the plurality of power distribution ranges is established;

[0066] S244, the correspondence between the fixed points in the plurality of power distribution ranges and the power distribution types in the planning library is established to obtain the correspondence between the plurality of power distribution ranges and the plurality of standby power distribution ranges and the power distribution types in the planning library;

[0067] As described in steps S241-S244, a fixed point is selected in each of the multiple power distribution ranges in the power distribution model, and a corresponding cloud server is configured for the fixed point as a position in the power distribution range and the corresponding fixed point. Then, the position of the fixed point in the multiple backup power distribution ranges is obtained as a follower fixed point, and a corresponding cloud server is configured for the follower fixed point as a position in the backup power distribution range. The communication relationship between the follower fixed point and the fixed point is the communication relationship between the corresponding cloud servers. The communication relationship between the fixed points is the communication relationship between the corresponding cloud servers. Then, the communication relationship between the follower fixed points of the multiple backup power distribution ranges and the fixed points is established to obtain multiple communication layers. The communication layers are fixed and coded to obtain communication layer identities. The communication layers are used to display the power distribution structures of the backup power distribution ranges in the subsequent sequential planning library load display. Then, the communication relationship between the fixed points in the multiple power distribution ranges is established. In order to connect the power distribution structures of the multiple backup power distribution ranges of the multiple power distribution ranges to each other, the communication relationship between the fixed points in the multiple power distribution ranges is combined to virtually connect and combine the power distribution structures of the multiple backup power distribution ranges of the multiple power distribution ranges. This is the subsequent power distribution network planning scheme. Then, the communication relationship between the fixed points in the multiple power distribution ranges and the planning library is established, i.e., the communication relationship between the cloud servers and the planning library. The corresponding relationship between the power distribution ranges and the multiple backup power distribution ranges and the power distribution types in the planning library is obtained. The fixed points can obtain the power distribution structures of the corresponding power distribution types in the planning library. The data can be combined and communicated. The power distribution structures can be better combined to obtain an optimal power distribution planning scheme, which greatly improves the comprehensiveness of the scheme combination.

[0068] In one embodiment, the step S3 of loading one or more power distribution structures in the planning library into the corresponding backup power distribution ranges based on the corresponding relationship to obtain one or more unit models comprises:

[0069] S31, obtaining one or more power distribution structures in the planning library based on the corresponding relationship through the fixed points in the power distribution range;

[0070] S32, storing the one or more power distribution structures into the corresponding communication layer through the communication relationship between the fixed points in the power distribution range and the corresponding follower fixed points to obtain one or more unit models;

[0071] As described in steps S31 and S32, one or more power grid structures corresponding to the planning library are obtained through the fixed point in the power distribution range based on the correspondence relationship. The power grid structure is the power grid structure for the existing power distribution range to implement the power distribution network planning. One or more power grid structures are provided to the corresponding communication layer to obtain one or more unit models. One communication layer corresponds to one power grid structure, which can ensure the cooperation of the power grid structure between multiple power distribution ranges and obtain the optimal power distribution network structure.

[0072] In one embodiment, the step S4 of matching the unit models between the multiple power distribution ranges based on the power distribution model to obtain multiple power distribution network planning schemes includes:

[0073] S41, freely combining one or more communication layers in the multiple standby power distribution ranges to obtain multiple combination schemes;

[0074] S42, based on the communication relationship between the fixed points in the multiple power distribution ranges, the unit models of the multiple standby power distribution ranges in a single combination scheme are communicatively connected, and the multiple unit models are connected in parallel through the parallel grid end to obtain a power distribution network planning scheme;

[0075] S43, multiple combination schemes obtain multiple power distribution network planning schemes;

[0076] As described in steps S41-S43, each communication layer stores different power grid structures, and the same standby power distribution range corresponds to the same power grid structure of the same power distribution type. Then, one or more communication layers in the multiple standby power distribution ranges are freely combined to obtain multiple combination schemes. Here, it is a simple combination. Since the fixed points in the power distribution range are communicatively connected to the follower fixed points in the corresponding multiple standby power distribution ranges, the communication between the follower fixed points in the corresponding multiple standby power distribution ranges in the power distribution range and the follower fixed points in the multiple standby power distribution ranges in other power distribution ranges can be completed through the fixed points in the power distribution range. Thus, the unit models in the corresponding communication layers in the multiple power distribution ranges can be connected in parallel. The parallel connection of the unit models is the parallel connection of the power grid structures stored in the unit models. Then, based on the communication relationship between the fixed points in the multiple power distribution ranges, the unit models of the multiple standby power distribution ranges in a single combination scheme are communicatively connected, and the multiple unit models are connected in parallel through the parallel grid end to obtain a power distribution network planning scheme. Multiple combination schemes obtain multiple power distribution network planning schemes. Multiple power distribution network planning schemes can be obtained, which can provide reference for the environment of setting up a power grid with multiple planning schemes and ensure the comprehensiveness of the power grid selection. When the optimal power distribution structure is selected, the optimal power distribution network planning scheme can be ensured.

[0077] In one embodiment, the step S5 of selecting the optimal power distribution network planning scheme from the plurality of power distribution network planning schemes as the target planning scheme comprises:

[0078] S51, input the required attribute information, and obtain a preferred index in the plurality of power distribution network planning schemes, wherein a calculation formula of the preferred index is:

[0079] Wherein, δ is the preferred index, T i is an investment attribute cost of a power distribution network structure in a unit model, ε i is a basic weight of the investment attribute cost of the power distribution network structure in the unit model, Tsx i is a demand weight of the investment attribute cost of the power distribution network structure in the unit model, J i is a level information of a technical attribute of the power distribution network structure in the unit model, σ i is a basic weight of the technical attribute of the power distribution network structure in the unit model, Jsx i is a demand weight of the technical attribute of the power distribution network structure in the unit model, and n represents a number of unit models in a single power distribution network planning scheme, that is, a number of power distribution ranges. It should be noted that the greater the values of T i , Tsx i and J i and Jsx i , the greater the value of δ, which represents a greater demand of the staff for building the power distribution network.

[0080] S52, ranking according to the preferred index, and taking a power distribution network planning scheme corresponding to a first ranked preferred index as the target planning scheme.

[0081] As described in the steps S51 and S52, the staff inputs the required attribute information, for example, the investment cost occupies the main demand, and the technical attribute occupies the general demand, so that the value of Tsx i is relatively large, and the value of Jsx i is relatively small. Then, the preferred index is obtained. The level information of the technical attribute of the power distribution network structure in the unit model is preset evaluation level information of attributes such as power supply capacity and reliability. The level information is a level value, for example, 1-10 levels. The greater the value, the better the attributes such as power supply capacity and reliability. If there is no demand, the values of Tsx i and Jsx i are both zero. Then, the preferred index is calculated according to the formula of the preferred index. The power distribution network planning schemes are arranged from large to small according to the preferred index. The power distribution network planning scheme corresponding to the first ranked preferred index is taken as the target planning scheme.

[0083] An acquisition module is configured to acquire a planning range of the power distribution network planning and acquire power distribution demand information in the planning range, wherein the power distribution demand information includes a plurality of power distribution ranges and corresponding load demands, and a power distribution model is constructed based on the planning range and the power distribution demand information.
