[0022] Hereinafter, exemplary embodiments according to this application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.
[0023] Figure 1 This is a schematic diagram of the structure of an active power distribution network monitoring system provided in an exemplary embodiment of this application. For example... Figure 1 As shown, the monitoring system for the active power distribution network includes: a model data module 11, an operation data module 12, a photovoltaic data module 13, and a monitoring platform 14. The model data module 11 is used to store power model data, which includes power data of the active power distribution network operation. The operation data module 12 is used to store power operation data and dispatch management data, which includes the power fed back to the substation by the distributed photovoltaic system and the data generated by the active power distribution network executing a preset workflow. The photovoltaic data module 13 is used to store distributed photovoltaic power data and distributed model data, which includes power data of the distributed photovoltaic system operation and the distributed model data represents the data obtained by processing the distributed photovoltaic operation data according to a first preset model. The monitoring platform 14 is communicatively connected to the model data module 11, the operation data module 12, and the photovoltaic data module 13, and is used to display the power model data, power operation data, dispatch management data, distributed photovoltaic model data, and distributed photovoltaic power data on the control cloud interface 15.
[0024] The model data module 11 stores power model data, which is obtained by processing power data in a preset database based on a second preset model. The data in the preset database can be manually input or received from power data related to active power distribution network equipment. The operation data module stores power operation data and dispatch management data. Dispatch management data includes data on the transmission of remaining power to substations after distributed photovoltaic (PV) operation. Typically, substations distribute power to distributed PV systems, which operate according to the distributed power. If the distributed power exceeds the rated power of the distributed PV systems, the remaining power will be sent to the substation, causing damage. Dispatch management data includes data on the active power distribution network executing preset workflows, such as the number of tickets for executing preset workflows, which represents the number of work instructions. The PV data module stores distributed PV power data and distributed model data. Distributed power data is obtained by processing the power data of distributed PV operation, while distributed model data is obtained by processing the operation data of distributed PV based on a first preset model. Then, the analysis and display server of the monitoring platform 14 sends the power model data, power operation data, dispatch management data, distributed photovoltaic model data, and distributed photovoltaic power data to the control cloud interface 15 for display. Furthermore, in this application, "upward transmission" can be understood as distributed photovoltaic power or electricity being fed back to the substation, while "downward transmission" is the opposite. Upward transmission indicates that the photovoltaic power cannot be consumed locally and can only be transmitted to the substation.
[0025] This application provides a monitoring system for an active power distribution network, comprising: a model data module, an operation data module, a photovoltaic data module, and a monitoring platform.

Through the model data module, operation data module, and photovoltaic data module, power model data, power operation data, dispatch management data, distributed photovoltaic model data, and distributed photovoltaic power data are displayed on the control cloud interface. Since the power operation data includes comprehensive data (upstream data) of the remaining power after the local consumption saturation of distributed photovoltaic power is transmitted to the substation, the monitoring platform can display the downstream data, thereby providing it for operators to view.
[0026] Figure 2 This is a schematic diagram of the structure of a monitoring system for an active power distribution network provided in another exemplary embodiment of this application. For example... Figure 2 As shown, the monitoring platform 14 includes a cluster module 141, which is connected to the model data module 11, the operation data module 12, the photovoltaic data module 13 and the control cloud interface 15.

[0027] The cluster module in the monitoring platform can communicate with the model data module 11, the operation data module 12, the photovoltaic data module 13, and the control cloud interface 15. The cluster module merges power model data, dispatch management data, distributed photovoltaic model data, power operation data, and distributed photovoltaic power data to obtain merged data, and displays the merged data on the control cloud interface. The cluster module 141 can be an ETL cluster (the essence of ETL work is to extract data from various data sources, transform the data, and finally load and populate the data into the tables after data warehouse dimensional modeling). Using the ETL cluster, the model data module 11, the operation data module 12, and the photovoltaic data module 13 can be run in parallel to improve the operating speed of the monitoring platform.
[0028] Figure 3This is a schematic diagram of the structure of a monitoring system for an active power distribution network provided in another exemplary embodiment of this application. For example... Figure 3 As shown, the monitoring platform 14 includes a first database 16, which stores data related to the active power distribution network.
[0029] The first database 16 can be a high-performance database management system. The first database 16 stores all the operating data related to the active power distribution network. In other words, the data stored in the first database 16 is extensive and comprehensive.

The active distribution network power transmission rate represents the power of the remaining power of the active distribution network transmitted to the substation.
[0035] The formula for calculating the power transmission rate of an active distribution network is equal to the number of active distribution network lines transmitting power within the target area divided by the total number of active distribution network lines within the target area.
