[0028] Figure 1A flowchart of a method for processing photovoltaic installation requests provided in an embodiment of the present invention. This embodiment can be applied to provide the power grid planning bureau with accurate remaining power capacity in the substation area, so that the power grid planning bureau can determine whether users who need to install photovoltaic equipment can install the equipment based on the capacity. The method can be executed by a photovoltaic installation request processing device, which can be implemented in the form of hardware and / or software, and can be configured in an electronic device. In this embodiment, the electronic device can be a computer or a terminal device. Figure 1 As shown, the method includes:

[0029] S101. Obtain photovoltaic installation request information, wherein the photovoltaic installation request information is used to indicate that the target user requests to install photovoltaic equipment, and the photovoltaic installation request information includes the installation capacity of the photovoltaic equipment and the substation area corresponding to the photovoltaic equipment.

[0030] The target user is a user who requests to install a photovoltaic device. In this embodiment, the photovoltaic device to be installed by each target user corresponds to a station area.

[0031] Specifically, after the target user submits a request to install photovoltaic equipment to the grid planner or grid installation personnel online or offline, the photovoltaic installation request information will be obtained. In addition to the photovoltaic equipment installation capacity and the corresponding substation area, the photovoltaic equipment model, name, type, and rated data information of the photovoltaic equipment can also be included in the photovoltaic installation request information.

[0032] In this embodiment, by obtaining the photovoltaic installation request information of the target user, data support is provided for subsequently determining the corresponding remaining power capacity of the substation according to the photovoltaic installation request information.

[0033] S102. Determine the predicted remaining power capacity corresponding to the substation according to the reported capacity and the historical maximum power of the substation, wherein the predicted remaining power capacity is the remaining power capacity corresponding to the backend area after simulating the connection of photovoltaic equipment to the substation.

[0034] The historical maximum power of the area is the annual maximum power value of the area in the historical process. In this embodiment, the historical maximum power of the area can be the maximum power value of any year in the historical process of the area, or the average value of the maximum power values ​​of any few years in the historical process of the area.

[0035] Specifically, each substation has a rated capacity, which is the maximum capacity that the substation can carry. And after the photovoltaic equipment installed by the user is connected to the substation, the corresponding connected installed capacity of the substation will be known. Therefore, according to the required installed capacity and the historical maximum power of the substation, the predicted remaining power capacity corresponding to the substation can be determined based on the rated capacity of the substation and the connected installed capacity.

[0036] For example, the reported capacity can be used to subtract the corresponding capacity value calculated by the historical maximum power of the substation, and then add the reported capacity corresponding to the substation to obtain the predicted access capacity value of the substation. Finally, the predicted remaining power capacity can be determined by subtracting the predicted access capacity value from the rated capacity of the substation.

[0037] In this embodiment, the reported capacity and the historical maximum power of the substation are used to determine the predicted remaining power capacity corresponding to the substation, so that accurate calculation can be achieved after simulating the connection of the photovoltaic equipment required to be installed by the target user to this substation. The predicted value of the remaining power capacity corresponding to the substation is achieved, which provides a basis for determining whether the substation can absorb the photovoltaic equipment required to be installed by the target user.

[0038] S103: If the predicted remaining power capacity does not meet a preset threshold, determine and display first processing information, where the first processing information is used to indicate that the target user's installation request is rejected, and the first processing information at least includes the predicted remaining power capacity.

[0039] The preset threshold is the minimum threshold for judging the remaining power capacity determined by the area planner based on the rated capacity, actual situation and safety conditions of the area. In this embodiment, if the remaining power capacity does not meet the preset threshold, it may cause dangerous problems such as power overload and unstable grid operation in the current area.

[0040] Specifically, if the predicted remaining power capacity does not meet the preset threshold, it can be determined that under the assumption that the target user's installed photovoltaic equipment is absorbed in the substation this time, the predicted remaining power capacity of the substation cannot meet the preset threshold. If the target user's photovoltaic equipment is forcibly absorbed in the substation, it may cause dangerous problems such as power overload and unstable grid operation in the current substation. Therefore, the first processing information can be determined and displayed so that the substation planner and the target user can determine the processing result. And it can make the target user more intuitively and clearly predict that the remaining power capacity is insufficient, that is, the corresponding remaining power capacity of the back-end area of ​​the simulated photovoltaic equipment connected to the substation cannot meet the requirements, so the target user's installation request will be rejected this time.

[0041] In this embodiment, if the predicted remaining power capacity does not meet the preset threshold, the first processing information is determined and displayed, so as to accurately determine that after the substation continues to consume the photovoltaic equipment reported by the target user, the remaining power capacity of the substation cannot meet the preset threshold. Therefore, in order to ensure the safe operation of the substation, it is impossible to continue to install photovoltaic equipment in the substation. In addition, the processing information of the photovoltaic installation request information is displayed to the substation planner and the target user, so that the target user can clearly understand the processing result of the installation request and the reason why the photovoltaic equipment cannot be installed.

[0042] S104: If the predicted remaining power capacity meets a preset threshold, determine and display second processing information, where the second processing information is used to indicate that the target user's installation request is approved.

[0043] Specifically, if the predicted remaining power capacity meets the preset threshold, it can be determined that if the target user's installed photovoltaic equipment is consumed in the substation this time, the predicted remaining power capacity of the substation can meet the preset threshold. Therefore, the second processing information can be determined and displayed so that the substation planner and the target user can determine the processing result.

[0044] In this embodiment, if the predicted remaining power capacity meets the preset threshold, the second processing information is determined and displayed, so that it is accurately determined that after the substation continues to consume the photovoltaic equipment reported by the target user, the remaining power capacity of the substation can meet the preset threshold, so the photovoltaic equipment can continue to be installed in the substation this time. And the processing information for the photovoltaic installation request information is displayed to the substation planner and the target user, so that the substation planner can clearly understand the processing result of the installation request and the remaining power capacity corresponding to the back-end area after the photovoltaic equipment is installed.

[0045] It is worth noting that steps S103 and S104 are parallel steps, that is, after executing S102, it is determined whether to execute S103 or S104 based on the predicted remaining power capacity and a preset threshold.

[0046] The method for processing photovoltaic installation requests provided in the embodiment of the present invention obtains photovoltaic installation request information, wherein the photovoltaic installation request information is used to indicate that the target user requests to install photovoltaic equipment, and the photovoltaic installation request information includes the installed capacity of the photovoltaic equipment and the substation corresponding to the photovoltaic equipment; according to the installed capacity and the historical maximum power of the substation, the predicted remaining power capacity corresponding to the substation is determined, wherein the predicted remaining power capacity is the remaining power capacity corresponding to the back-end area of ​​the substation that simulates connecting the photovoltaic equipment to the substation; if the predicted remaining power capacity does not meet the preset threshold, the first processing information is determined and displayed, and the first processing information is used to indicate the rejection of the target user's installation request, and the first processing information at least includes the predicted remaining power capacity; if the predicted remaining power capacity meets the preset threshold, the second processing information is determined and displayed, and the second processing information is used to indicate the approval of the target user's installation request. In the above technical scheme, on the one hand, by obtaining the photovoltaic installation request information of the target user, data support is provided for determining the remaining power capacity corresponding to the substation according to the photovoltaic installation request information. On the other hand, the predicted remaining power capacity corresponding to the substation is determined by using the reported capacity and the historical maximum power of the substation, so as to accurately calculate the predicted value of the remaining power capacity corresponding to the substation after simulating the connection of the photovoltaic equipment required to be installed by the target user to the substation, and provide a basis for determining whether the substation can absorb the photovoltaic equipment required to be installed by the target user. Finally, if the predicted remaining power capacity does not meet the preset threshold, the first processing information is determined and displayed, so as to accurately determine that after the substation continues to absorb the photovoltaic equipment reported by the target user, the remaining power capacity of the substation cannot meet the preset threshold. Therefore, in order to ensure the safe operation of the substation, the photovoltaic equipment cannot be installed in the substation this time. And, the processing information for the photovoltaic application request information is displayed to the substation planning personnel and the target user, so that the target user can clearly understand the processing result of the application request and the reason why the photovoltaic equipment cannot be installed. Alternatively, if the predicted remaining power capacity meets the preset threshold, the second processing information is determined and displayed, so as to accurately determine that after the substation continues to absorb the photovoltaic equipment reported by the target user, the remaining power capacity of the substation can meet the preset threshold, so the photovoltaic equipment can be installed in the substation this time. Furthermore, the processing information of the photovoltaic installation request information is displayed to the substation planning personnel and the target users, so that the substation planning personnel can clearly understand the processing result of this installation request and the remaining power capacity corresponding to the background area after the photovoltaic equipment is installed.

[0047] Figure 2 Another flowchart of the method for processing a photovoltaic installation request provided by an embodiment of the present invention is shown. Figure 1Based on the illustrated embodiment and various optional implementations, this embodiment describes the steps after "obtaining photovoltaic installation request information", the steps of "determining the predicted remaining power capacity corresponding to the area according to the installed capacity and the historical maximum power of the area", and the steps after determining and displaying the processing information. Figure 2 As shown, the method includes:

[0048] S201. Obtain photovoltaic installation request information.

[0049] Specifically, after the target user submits a request to install photovoltaic equipment to the grid planner or grid installation personnel online or offline, the photovoltaic installation request information will be obtained. In addition to the photovoltaic equipment installation capacity and the corresponding substation area, the photovoltaic equipment model, name, type, and rated data information of the photovoltaic equipment can also be included in the photovoltaic installation request information.

[0050] In this embodiment, by obtaining the photovoltaic installation request information of the target user, data support is provided for subsequently determining the corresponding remaining power capacity of the substation according to the photovoltaic installation request information.

[0051] S202, determine whether the current remaining power capacity corresponding to the substation meets the preset threshold; if so, execute S203; if not, execute S209.

[0052] Among them, the current remaining power capacity is the remaining power capacity of the substation based on the photovoltaic equipment that has been connected.

[0053] Specifically, a substation includes: the substation to which the photovoltaic equipment belongs and all distribution transformers and lines included in the substation; the current remaining power capacity includes the current remaining capacity of the distribution transformer, the current remaining capacity of the line and the current remaining capacity of the substation.

[0054] For example, in a substation, there may be 24 lines in a substation area, and a line may include dozens of distribution transformers. The photovoltaic equipment will be connected to a distribution transformer through the distribution transformer box at its location. A distribution transformer corresponds to a line, and a line corresponds to a substation. Therefore, the current remaining power capacity includes the current remaining capacity of the distribution transformer corresponding to the photovoltaic equipment, the current remaining capacity of the line corresponding to the distribution transformer, and the current remaining capacity of the substation of the substation corresponding to the photovoltaic equipment.

[0055] Specifically, to determine whether the current remaining power capacity corresponding to the substation meets the preset threshold, it is necessary to determine whether the current remaining capacity of the distribution transformer, the current remaining capacity of the line and the current remaining capacity of the substation all meet the preset threshold.

[0056] Exemplarily, the current remaining power capacity corresponding to the station area may be determined in the following manner:

[0057] (1) Obtain the capacity information of the substation area.

[0058] Among them, the substation capacity information includes the rated capacity of the distribution transformer, the connected capacity of the distribution transformer, the rated capacity of the line, the connected capacity of the line, the rated capacity of the substation, and the connected capacity of the substation.

[0059] Specifically, the current remaining power capacity corresponding to the substation is related to the rated capacity and connected capacity of the distribution transformer, line and substation in the substation. Therefore, we can first obtain the rated capacity and connected capacity of each distribution transformer in the substation, the rated capacity and connected capacity of each line, and the rated capacity and connected capacity of the substation corresponding to the distribution transformer corresponding to the photovoltaic equipment requested to be installed by the target user.

[0060] Exemplarily, the connected capacity of the distribution transformer is the sum of the capacities of all connected photovoltaic devices corresponding to the distribution transformer. For example, the photovoltaic installation request information corresponding to the distribution transformer in the historical process is obtained, and the sum of the capacities of the connected photovoltaic devices is determined according to the installed capacities of all connected photovoltaic devices in the historical process corresponding to the distribution transformer recorded in the photovoltaic installation request information.

[0061] Exemplarily, the connected capacity of a line is the sum of the connected capacities of all distribution transformers on the line. For example, the connected capacities of all distribution transformers on the line are obtained and summed to obtain the sum of the connected capacity of the line.

[0062] Exemplarily, the connected capacity of the substation is the sum of the connected capacities of all the lines on the substation. For example, the connected capacities of all the lines on the substation are obtained and summed to obtain the sum of the connected capacity of the substation.

[0063] For example, the rated capacity of the distribution transformer, the rated capacity of the line, and the rated capacity of the substation can be determined by corresponding equipment or relevant information provided by the power planning department.

[0064] (2) Determine the current remaining capacity of the distribution transformer based on the rated capacity of the distribution transformer and the connected capacity of the distribution transformer.

[0065] Specifically, the current remaining capacity of the distribution transformer may be determined by using the rated capacity of the distribution transformer and the connected capacity of the distribution transformer.

[0066] Exemplarily, the current remaining capacity of the distribution transformer can be obtained by subtracting the connected capacity of the distribution transformer from the rated capacity of the distribution transformer.

[0067] (3) Determine the current remaining capacity of the line based on the rated capacity of the line and the connected capacity of the line.

[0068] Specifically, the current remaining capacity of the line may be determined by using the rated capacity of the line and the connected capacity of the line.

[0069] Exemplarily, the current remaining capacity of the line can be obtained by subtracting the connected capacity of the line from the rated capacity of the line.

[0070] (4) Determine the current remaining capacity of the substation based on the rated capacity of the substation and the connected capacity of the substation.

[0071] Specifically, the current remaining capacity of the substation may be determined by using the rated capacity of the substation and the connected capacity of the substation.

[0072] Exemplarily, the current remaining capacity of the substation can be obtained by subtracting the connected capacity of the substation from the rated capacity of the substation.

[0073] Specifically, since the remaining capacity of the substation is related to the sum of the capacities of all lines connected to the substation, and the remaining capacity of each line is related to the sum of the capacities of all distribution transformers connected to the line, if only the remaining capacity of the distribution transformer is calculated, the remaining capacity of the corresponding line may be exceeded, or if only the remaining capacity corresponding to the distribution transformer and the line is calculated, the remaining capacity of the corresponding substation may be exceeded. Therefore, according to the above, after calculating the current remaining capacity of electricity corresponding to the substation area according to the above steps, it can be determined whether the current remaining capacity of the distribution transformer, the current remaining capacity of the line and the current remaining capacity of the substation corresponding to the current remaining capacity of electricity in the substation area meet the preset threshold. If so, it means that the current remaining capacity of electricity in the current substation area may meet the registration requirements of the target user. Therefore, it is possible to continue to simulate the remaining capacity of electricity corresponding to the back-end area of ​​the photovoltaic equipment connected to the substation area, so as to determine the remaining capacity of electricity in the substation area after the simulated access. If not, it means that the current remaining capacity of electricity in the substation area can no longer meet the registration requirements of the target user, so the third processing information can be directly determined and displayed.

[0074] Exemplarily, the calculated current remaining capacity of the distribution transformer, the current remaining capacity of the line and the current remaining capacity of the substation should all meet the corresponding preset thresholds. For example, the current remaining capacity of the distribution transformer needs to be less than the preset distribution transformer threshold, the current remaining capacity of the line needs to be less than the preset line threshold, and the current remaining capacity of the substation needs to be less than the preset substation threshold.

[0075] In this embodiment, by first calculating the current remaining power capacity corresponding to the substation, and depending on whether the current remaining capacity of the distribution transformer, the current remaining capacity of the line and the current remaining capacity of the substation in the current remaining power capacity meet the preset thresholds, it is judged whether the current substation still has remaining capacity to absorb the target user's photovoltaic application.

[0076] S203: Obtain the capacity information of the substation area.

[0077] Specifically, after determining that the current remaining power capacity corresponding to the substation meets a preset threshold, the substation capacity information may be directly acquired.

[0078] S204. Determine the predicted remaining capacity of the distribution transformer according to the rated capacity of the distribution transformer, the connected capacity of the distribution transformer, the reported capacity and the historical maximum power of the distribution transformer.

[0079] The historical maximum power of the distribution transformer may be a maximum power value of a certain year in the history of the distribution transformer, or may be an average value of maximum power values ​​in recent years in the history.

[0080] Specifically, the sum of the predicted access capacity of the distribution transformer can be determined according to the connected capacity, the reported capacity and the historical maximum power of the distribution transformer, and the predicted remaining capacity of the distribution transformer can be determined according to the sum of the rated capacity of the distribution transformer and the predicted access capacity of the distribution transformer.

[0081] For example, it is assumed that the distribution transformer a corresponds to the photovoltaic power reported by the target user, and the distribution transformer a corresponds to the line A, and the line A corresponds to the substation 1. Then the predicted remaining capacity of the distribution transformer a can be calculated. For example, the sum of the reported capacities of the distribution transformer a corresponding to the photovoltaic power reported this time is obtained, and the historical maximum power of the distribution transformer a is subtracted to obtain the predicted access capacity of the distribution transformer a. The predicted remaining capacity of the distribution transformer a can be determined by subtracting the predicted access capacity of the distribution transformer a from the rated capacity of the distribution transformer a. Among them, the sum of the reported capacities is the sum of the reported total capacity of the connected distribution transformer a and the reported capacity that needs to be connected in this simulation.

[0082] S205. Determine the predicted remaining capacity of the line according to the rated capacity of the line, the connected capacity of the line, the reported capacity and the historical maximum power of the line.

[0083] The connected capacity of the line is the sum of the connected capacities of all distribution transformers in the line. The historical maximum power of the line can be the maximum power value of a certain year in the history of the line, or the average value of the maximum power values ​​in recent years in the history.

[0084] Specifically, the connected capacity of the line can be determined based on the connected capacity and the reported capacity of the distribution transformer. The sum of the predicted connected capacity of the line can be determined based on the connected capacity of the line and the historical maximum power of the line. The predicted remaining capacity of the line can then be determined based on the sum of the rated capacity of the line and the predicted connected capacity of the line.

[0085] Exemplarily, following the above example, since distribution transformer a is located in line A, for all distribution transformers in line A, if it is distribution transformer a, the sum of the reported capacities of distribution transformer a corresponding to the current photovoltaic installation is obtained, and the historical maximum power of distribution transformer a is subtracted to obtain the predicted access capacity of distribution transformer a. If it is other distribution transformers in line A, the connected capacity of the distribution transformer is directly determined. The access capacity of all distribution transformers in line A is added, that is, the predicted access capacity of distribution transformer a plus the connected capacity of all distribution transformers corresponding to non-distribution transformer a, to obtain the sum of the predicted access capacity of the distribution transformer. The sum of the predicted access capacity of the distribution transformer minus the historical maximum power of line A can be used to obtain the line predicted access capacity of line A. The rated capacity of line A minus the line predicted access capacity of line A can determine the line predicted remaining capacity of line A.

[0086] S206. Determine the predicted remaining capacity of the substation according to the rated capacity of the substation, the connected capacity of the substation, the reported capacity and the historical maximum power of the substation.

[0087] The connected capacity of the substation is the sum of the connected capacities of all lines in the substation. The historical maximum power of the substation can be the maximum power value of a certain year in the history of the substation, or the average value of the maximum power values ​​in recent years in the history.

[0088] Specifically, the connected capacity of the line can be determined based on the connected capacity and reported capacity of the distribution transformer. The connected capacity of the substation can be determined based on the connected capacity of the line. The sum of the substation's predicted connected capacity can be determined based on the substation's connected capacity and the substation's historical maximum power. The predicted remaining capacity of the substation can then be determined based on the sum of the substation's rated capacity and the substation's predicted connected capacity.

[0089] Exemplarily, following the above example, since distribution transformer a is located in line A, and line A is located in substation 1, for all lines in substation 1, if it is line A, the line predicted access capacity of line A is obtained. If it is other lines in substation 1, the connected capacity of the line is directly determined. Adding the access capacities of all lines in substation 1, that is, the line predicted access capacity of line A plus the connected capacity of all lines corresponding to non-line A, the sum of the line predicted access capacities can be obtained. The sum of the line predicted access capacities minus the historical maximum power of substation 1 can obtain the substation predicted access capacity of substation 1. The rated capacity of substation 1 minus the substation predicted access capacity of substation 1 can determine the substation predicted remaining capacity of substation 1.

[0090] In this embodiment, after determining that the current remaining power capacity corresponding to the substation meets the preset threshold, the substation capacity information and the distribution transformer, line and substation corresponding to the photovoltaic equipment requested to be installed by the target user are used to further simulate the predicted remaining capacity of the distribution transformer, line predicted remaining capacity and substation predicted remaining capacity of the photovoltaic equipment connected to the back-end area of ​​the substation. This provides a basis for determining whether the current substation can absorb the photovoltaic equipment based on the simulation of the predicted remaining capacity of the distribution transformer, line predicted remaining capacity and substation predicted remaining capacity of the photovoltaic equipment connected to the back-end area of ​​the substation.

[0091] S207: If the predicted remaining power capacity does not meet the preset threshold, determine and display the first processing information; and continue to execute S210.

[0092] Specifically, if any one of the predicted remaining capacity of the distribution transformer, the predicted remaining capacity of the line, and the predicted remaining capacity of the substation in the predicted remaining power capacity does not meet the preset threshold, it can be determined that under the assumption that the target user's installed photovoltaic equipment is absorbed in the substation this time, the predicted remaining power capacity of the substation cannot meet the preset threshold. If the target user's installed photovoltaic equipment is forcibly absorbed in the substation, it may cause dangerous problems such as power overload and unstable grid operation in the current substation. Therefore, the first processing information can be determined and displayed so that the substation planner and the target user can determine the processing result. And it can make the target user more intuitively and clearly predict that the remaining power capacity is insufficient, that is, the simulation of connecting the photovoltaic equipment to the back-end area of ​​the substation cannot meet the requirements, so the target user's installation request will be rejected this time.

[0093] Exemplarily, predicting that the remaining power capacity does not meet a preset threshold may include:

[0094] (1) The predicted remaining capacity of the distribution transformer is less than the preset distribution transformer threshold. (2) The predicted connected capacity of line A corresponding to distribution transformer a is greater than 80% of the rated capacity of line A, and the predicted remaining capacity of the distribution transformer of distribution transformer a is 0. (3) The predicted connected capacity of line A corresponding to distribution transformer a is less than 80% of the rated capacity of line A, but greater than 50% of the rated capacity of line A, and the predicted remaining capacity of the distribution transformer is the minimum value between (rated capacity of line A - connected capacity of line A) and (rated capacity of distribution transformer a - connected capacity of distribution transformer a). (4) The line predicted remaining capacity is less than the preset line threshold. (5) The predicted connected capacity of substation 1 corresponding to line A is greater than 80% of the rated capacity of any main transformer in substation 1, and the line predicted remaining capacity of line A is 0. (6) Or the predicted connected capacity of substation 1 corresponding to line A is less than 80% of the rated capacity of any main transformer in substation 1, but greater than 50% of the rated capacity of any main transformer in substation 1, and the line predicted remaining capacity is the minimum value between (rated capacity of substation 1 - connected capacity of substation 1) and (rated capacity of line A - connected capacity of line A). (7) The case where the substation does not meet the preset threshold: the predicted remaining capacity of the substation is less than the preset substation threshold.

[0095] It is worth noting that after the first processing information is determined and displayed, step S210 may continue to be executed.

[0096] S208: If the predicted remaining power capacity meets a preset threshold, determine and display second processing information.

[0097] Specifically, if each of the predicted remaining capacity of the distribution transformer, the predicted remaining capacity of the line, or the predicted remaining capacity of the substation in the predicted remaining power capacity meets the preset threshold, it can be determined that assuming that the photovoltaic equipment installed by the target user is absorbed in the substation this time, the predicted remaining power capacity of the substation can meet the preset threshold. Therefore, the second processing information can be determined and displayed so that the substation planner and the target user can determine the processing result. The processing result is that the photovoltaic equipment that the target user needs to install this time can be absorbed in the substation.

[0098] In this embodiment, after determining that the current remaining power capacity of the substation is likely to meet the installation needs of the target user, a simulation is performed to determine whether the predicted remaining power capacity corresponding to the back-end area of ​​the photovoltaic equipment connected to the substation meets the preset threshold; when the predicted remaining power capacity meets the preset threshold, the second processing information is determined and displayed so that the substation planning personnel can determine that the substation can meet the installation needs of the target user. When the predicted remaining power capacity does not meet the preset threshold, the first processing information is determined and displayed so that the substation planning personnel can determine that the substation cannot meet the installation needs of the target user, and the reason why the installation needs cannot be met is displayed to the user.

[0099] S209, determine and display the third processing information; and continue to execute S210.

[0100] The third processing information is used to indicate the rejection of the target user's installation request, and the third processing information at least includes the current remaining power capacity.

[0101] Specifically, when it is determined that the current remaining power capacity corresponding to the substation does not meet the preset threshold, it can be determined that the remaining power capacity of the current substation has been exhausted, that is, it cannot meet any additional installation requirements. Therefore, the third processing information can be determined and displayed so that the substation planner and the target user can determine the processing result. And it can make the target user more intuitively clear that the current remaining power capacity is insufficient, that is, the current substation can no longer meet any additional installation requirements, so the target user's installation request will be rejected this time.

[0102] In this embodiment, by first calculating the current remaining power capacity corresponding to the substation, if the current remaining power capacity cannot meet the preset threshold, the third processing information is directly determined and displayed, and there is no need to simulate connecting the photovoltaic equipment to the substation to determine whether the predicted remaining power capacity corresponding to the substation meets the preset threshold, so that the substation planner can determine that the substation cannot meet the installation needs of the target users, and show the users the reasons why their installation needs cannot be met.

[0103] It is worth noting that after the third processing information is determined and displayed, step S210 may continue to be executed.

[0104] S210, the count value of the area planning counter is increased by one.

[0105] The substation has a substation planning counter corresponding to it, which is used to record the number of rejected user requests after rejecting the target user's installation request. In this embodiment, the function of the substation planning counter is to remind the substation planning personnel that when the count value of the counter reaches a certain level, the power capacity of the substation needs to be expanded to reduce the negative emotions of users due to the inability to install the required photovoltaic equipment.

[0106] Specifically, after determining the first processing information or the third processing information, that is, after obtaining the result of the installation request for the target user: "Reject the target user's installation request", the count value of the planning counter of the station area will be added to the previous count value to record the number of times the target user's installation request has been rejected.

[0107] S211. If the count value of the area planning counter is greater than or equal to a preset planning threshold, the planning information is determined and displayed.

[0108] The planning information is used to indicate the number of times the user's installation request is rejected and prompt the user to plan the power for the area. The preset planning threshold is a planning threshold set in advance by the planner. When the count value of the counter reaches this threshold, it means that the area needs to be planned.

[0109] Specifically, if the count value of the area planning counter is less than the preset planning threshold, it means that the power capacity of the current area may be able to meet the installation needs of most users. Therefore, in order to ensure that there is no waste of electricity in the area, the power capacity of the current area will not be expanded for the time being. If the count value of the area planning counter is greater than or equal to the preset planning threshold, it means that the power capacity of the current area may not be able to meet the installation needs of most users. Therefore, in order to guarantee the user's installation needs, optimize the user's quality of life, and ensure the power safety of this area, it is necessary to determine and display the planning information of the power capacity of this area, so that the power planners can clearly understand the need to further plan the power capacity of this area.

[0110] S212: Obtain capacity limit information of the substation.

[0111] The capacity limit information of the substation area is used to indicate the remaining expandable capacity information of the substation area. The capacity limit information includes the distribution transformer capacity limit, the line capacity limit and the substation capacity limit.

[0112] Specifically, if the power capacity of the substation needs to be expanded, the maximum capacity limit of each power device needs to be determined according to the capacity limit information, that is, the expanded capacity cannot exceed its limit requirement.

[0113] S213. Collect the roof area information of the substation area, and determine the predicted installed capacity based on the roof area information.

[0114] The predicted installed capacity is the total capacity of photovoltaic equipment that users in this area may install in the future.

[0115] Specifically, since photovoltaic equipment is generally installed on the roofs of residential houses within the substation area, the predicted photovoltaic capacity can be calculated by simply determining the area of ​​the roof.

[0116] For example, the roof area can be determined directly from residents, or by using drones to take images of the roof and calculate the roof area based on image recognition technology and feature extraction technology. After the roof area is calculated, the predicted capacity can be calculated based on the remaining free area of ​​the roof and the area that each household photovoltaic system may occupy.

[0117] S214. Determine and display planning forecast information based on the capacity limit information of the substation and the predicted reported capacity.

[0118] The planning prediction information is the predicted capacity information that needs to be expanded in the substation area.

[0119] Specifically, the capacity information that needs to be expanded in the substation can be determined based on the capacity limit information and predicted reported capacity of the substation, and the information can be displayed so that power planners can expand the power capacity of the substation based on the information.

[0120] For example, the substation area includes the substation to which the photovoltaic equipment belongs and all the distribution transformers and lines included in the substation; the capacity limit information of the substation area includes the capacity limit of the distribution transformer, the capacity limit of the line and the capacity limit of the substation. According to the capacity limit information of the substation area and the predicted installed capacity, the planning prediction information can be determined and displayed according to the following steps:

[0121] (1) Determine the number of distribution transformers that need to be installed in the substation based on the capacity limit and predicted installed capacity of the distribution transformer.

[0122] Specifically, the number of distribution transformers that may be required can be calculated based on the predicted installed capacity and the capacity limit of the distribution transformer.

[0123] (2) Determine the number of additional lines required in the substation based on the line capacity limit and predicted installed capacity.

[0124] Specifically, after the possible required number of distribution transformers is determined, the possible required number of lines is calculated according to the possible required number of distribution transformers and the capacity limit of the line.

[0125] (3) Determine the number of substations that need to be installed in the area based on the capacity limit of the substation and the predicted installed capacity.

[0126] Specifically, after determining the number of distribution transformers and the number of lines that may be required, the number of substations that may be required is calculated based on the number of distribution transformers that may be required, the number of lines that may be required and the capacity limit of the substation.

[0127] (4) At least one of the number of distribution transformers, the number of lines and the number of substations is used as planning prediction information, and the planning prediction information is displayed.

[0128] Specifically, since a substation has its own power generation capacity, if the number of distribution transformers, lines and substations to be installed is determined based only on the predicted installed capacity, it may cause the power generation capacity of the entire substation to be large and its load to be too large. Therefore, in one implementation, when it is determined that it will not affect the power generation conditions of the substation, the more appropriate number of distribution transformers, lines and substations to be installed can be determined based on the number of distribution transformers, lines and substations. In another implementation, at least one of the number of distribution transformers, lines and substations is used as planning forecast information and displayed to planners.

[0129] In this embodiment, by counting the substation planning counter, after the user's request to install photovoltaic equipment is rejected, the value of the counter is increased by one until the value of the counter is greater than or equal to the preset planning threshold, the substation capacity limitation information is obtained and the predicted installation capacity is determined, and the planning prediction information is determined and displayed based on the substation capacity limit information and the predicted installation capacity. This achieves the expansion of the substation's power capacity when the remaining power capacity of the substation cannot meet the installation needs of most users, thereby improving the quality of life of users and reducing the negative emotions of users caused by the inability to install photovoltaic equipment.

[0130] The method for processing photovoltaic installation requests provided in an embodiment of the present invention obtains photovoltaic installation request information; determines whether the current remaining power capacity corresponding to the substation meets a preset threshold; if so, obtains the substation capacity information, determines the predicted remaining capacity of the distribution transformer according to the rated capacity of the distribution transformer, the connected capacity of the distribution transformer, the installed capacity and the historical maximum power of the distribution transformer, determines the predicted remaining capacity of the line according to the rated capacity of the line, the connected capacity of the line, the installed capacity and the historical maximum power of the line, and determines the predicted remaining capacity of the substation according to the rated capacity of the substation, the connected capacity of the substation, the installed capacity and the historical maximum power of the substation; if the predicted remaining power capacity does not meet the preset threshold, determines and displays the first processing information; if the predicted remaining power capacity meets the preset threshold, determines and displays the second processing information; if not, determines and displays the third processing information. And, after determining the first processing information or the third processing information, the count value of the area planning counter is increased by one; if the count value of the area planning counter is greater than or equal to the preset planning threshold, the planning information is determined and displayed; the capacity limit information of the area is obtained; the roof area information of the area is collected, and the predicted installed capacity is determined based on the roof area information; according to the capacity limit information of the area and the predicted installed capacity, the planning prediction information is determined and displayed. In the above technical scheme, on the one hand, by obtaining the photovoltaic installation request information of the target user, data support is provided for determining the corresponding power surplus capacity of the area according to the photovoltaic installation request information. And, by first calculating the current power surplus capacity corresponding to the area, according to whether the current remaining capacity of the distribution transformer, the current remaining capacity of the line and the current remaining capacity of the substation in the current power surplus capacity meet the preset thresholds, it is first judged whether the current area still has surplus capacity that may absorb the target user's photovoltaic installation. On the other hand, after determining that the current remaining power capacity corresponding to the substation meets the preset threshold, the substation capacity information and the distribution transformer, line and substation corresponding to the photovoltaic equipment requested to be installed by the target user are used to further simulate the predicted remaining capacity of the distribution transformer, line predicted remaining capacity and substation predicted remaining capacity of the photovoltaic equipment connected to the back-end area of ​​the substation. This provides a basis for determining whether the current substation can absorb the photovoltaic equipment this time based on the simulation of the predicted remaining capacity of the distribution transformer, line predicted remaining capacity and substation predicted remaining capacity of the photovoltaic equipment connected to the back-end area of ​​the substation. In addition, by first calculating the current remaining power capacity corresponding to the substation, if the current remaining power capacity cannot meet the preset threshold, the third processing information is directly determined and displayed, and there is no need to simulate the connection of the photovoltaic equipment to the substation to determine whether the predicted remaining power capacity corresponding to the substation meets the preset threshold, so that the substation planner can determine that the substation cannot meet the installation needs of the target user, and show the user the reason why their installation needs cannot be met.On the other hand, after determining that the current remaining power capacity of the substation is likely to meet the installation needs of the target user, simulate whether the predicted remaining power capacity corresponding to the back-end area of ​​the photovoltaic device connected to the substation meets the preset threshold; when the predicted remaining power capacity meets the preset threshold, determine and display the second processing information so that the substation planning personnel can determine that the substation can meet the installation needs of the target user. When the predicted remaining power capacity does not meet the preset threshold, determine and display the first processing information so that the substation planning personnel can determine that the substation cannot meet the installation needs of the target user, and show the user the reason why the installation needs cannot be met. Finally, through the counting of the substation planning counter, after rejecting the user's request to install photovoltaic equipment, the value of the counter is increased by one until the value of the counter is greater than or equal to the preset planning threshold, the substation capacity limitation information is obtained and the predicted installation capacity is determined, and the planning prediction information is determined and displayed according to the substation capacity limit information and the predicted installation capacity. In the case where the remaining power capacity of the substation cannot meet the installation needs of most users, the power capacity of the substation is expanded, the quality of life of users is improved, and the generation of negative emotions caused by the inability to install photovoltaic equipment is reduced.
