Description

Technical Field

[0001] This invention relates to the field of power grid control, and in particular to a multi-port flexible interconnection control method, system, device and medium. Background Technology

[0002] Multi-port flexible interconnection devices play a crucial role in the flexible control and optimization of power transmission in the power grid, and their stable operation is essential for the reliability and stability of the grid. A failure of these devices could lead to power outages in the areas they manage, affecting the normal electricity consumption of residents and businesses. Therefore, effective control of multi-port flexible interconnection devices enables timely fault detection and intervention, ensuring the stable operation of the power grid and the continuity of power supply.

[0003] To ensure the stable operation of the power grid and the continuity of power supply, existing technologies typically equip each distribution area with a set of backup equipment for flexible interconnection devices. While this strategy can switch to the backup equipment to maintain power supply in the event of a fault, it has obvious drawbacks: on the one hand, the purchase and maintenance of backup equipment increases the cost of the power grid system; on the other hand, due to the uncertainty of the fault time, the backup equipment is idle most of the time, which leads to a waste of resources. Summary of the Invention

[0004] This invention provides a multi-port flexible interconnection control method, system, device, and medium that can ensure the stable operation of the power grid while reducing resource waste.

[0005] An embodiment of the present invention provides a multi-port flexible interconnection control method, comprising:

[0006] The system obtains the first historical load information and real-time load information of the first flexible interconnect device, performs clustering based on the first historical load information to obtain several clustering results, and determines whether the first flexible interconnect device has failed based on each clustering result and the real-time load information.

[0007] If a fault occurs, the second historical load information of each second flexible interconnect device is obtained, and several backup devices in the second flexible interconnect device are determined based on the second historical load information. The target distance between the first flexible interconnect device and each backup device is calculated, and the backup device with the smallest target distance is determined as the target port flexible interconnect device. The second flexible interconnect device is an adjacent device that is in a preset area and located in a different station area from the first flexible interconnect device.

[0008] The load and distributed power supply of the first flexible interconnect device are connected to the target port flexible interconnect device so that the target port flexible interconnect device can perform load scheduling.

[0009] This invention, by acquiring the first historical load information and real-time load information of the first flexible interconnect device, can comprehensively understand the device's load characteristics and current operating status. Clustering can promptly detect whether a fault has been detected in the device, facilitating rapid subsequent measures to prevent the fault from escalating and thus ensuring the stable operation of the power grid. In the event of a fault, by quickly determining the target port flexible interconnect device based on the historical load information and distance of surrounding devices, mutual support between devices can be achieved without adding additional backup equipment, reducing the impact of the fault on the power grid and minimizing resource waste. By connecting the load of the first flexible interconnect device and distributed power sources to the target port flexible interconnect device, it can be ensured that the area originally powered by the faulty first flexible interconnect device can still receive a stable power supply in the event of a fault, thereby ensuring the stable operation of the power grid. Compared with existing technologies, this application can ensure the stable operation of the power grid while reducing resource waste.

[0010] Furthermore, the second flexible interconnect device is an adjacent device located in a preset area but in a different substation than the first flexible interconnect device, specifically:

[0011] Obtain the location information of the first flexible interconnect device, and determine the preset area based on the location information;

[0012] From the preset area, determine a plurality of third flexible interconnect devices adjacent to the first flexible interconnect device, and determine the area range of each third flexible interconnect device.

[0013] Based on the range of the transformer area, the third flexible interconnect device is selected to determine the second flexible interconnect device located in a different transformer area than the first flexible interconnect device.

[0014] This method of selecting multi-port flexible interconnected devices that are adjacent to the target device but located in different distribution areas based on location information allows for rapid switching of load and power to suitable devices in nearby distribution areas when the target device fails, ensuring stable operation of the power grid and avoiding the need for dedicated backup equipment, thus reducing resource waste.

[0015] Furthermore, the step of determining whether the first flexible interconnect device has malfunctioned based on the clustering results and the real-time load information specifically involves:

[0016] Based on the clustering results and the first historical load information, the corresponding load scheduling curve is determined.

[0017] Determine whether the real-time load information matches the load scheduling curve; if not, determine that the first flexible interconnect device has malfunctioned.

[0018] If the conditions are met, the vertical distance between the real-time load information and each of the clustering results is calculated. If the vertical distance exceeds a preset threshold range, it is determined that the first flexible interconnect device has malfunctioned.

[0019] By promptly identifying whether the first flexible interconnection device has malfunctioned, it is convenient to take corresponding measures to switch to power supply from the normal device, ensuring the stability of the power supply in the distribution area and avoiding the waste of resources caused by setting up backup equipment.

[0020] Furthermore, the step of connecting the load of the first flexible interconnect device and the distributed power supply to the target port flexible interconnect device, so that the target port flexible interconnect device can perform load scheduling, specifically involves:

[0021] Connect the load and distributed power supply of the first flexible interconnect device to the target port flexible interconnect device, and re-load schedule the load and distributed power supply of the first flexible interconnect device according to a preset control method.

[0022] If there is still remaining load after the reload scheduling is completed, the remaining load will be allocated to the target distributed power supply of the target port flexible interconnect device itself.

[0023] This reload scheduling avoids power outages caused by faults, ensuring the continuity of power supply. Furthermore, if there is still remaining load after reload scheduling, it is allocated to the target distributed power source within the flexible interconnection device itself. This fully utilizes existing distributed power sources, avoiding resource idleness and waste, thus achieving the goal of ensuring stable grid operation while reducing resource waste.

[0024] Furthermore, before connecting the load and distributed power supply of the first flexible interconnect device to the target port flexible interconnect device, the method further includes:

[0025] The port types of the first flexible interconnect device and the target port flexible interconnect device are determined respectively, and the corresponding cables are used to interconnect the ports according to the port types.

[0026] By determining the port type and using corresponding cables for interconnection, efficient and stable connections between various devices in the power grid are ensured to guarantee the stable operation of the power grid. At the same time, resource waste caused by mismatched port types or improper cable selection is avoided, thereby reducing the installation cost and achieving the goal of ensuring the stable operation of the power grid while reducing resource waste.

[0027] Furthermore, the step of using corresponding cables for port interconnection according to the port type specifically includes:

[0028] If the port type is an AC port, then a three-phase AC cable is used for port interconnection;

[0029] If the port type is a DC port, then a DC cable is used for port interconnection;

[0030] If the port type is a mixed AC / DC port, then three-phase AC cables and DC cables are used for port interconnection.

[0031] By determining the port type and using corresponding cables for interconnection, efficient and stable connections between various devices in the power grid are ensured to guarantee the stable operation of the power grid. At the same time, resource waste caused by mismatched port types or improper cable selection is avoided, thereby reducing the installation cost and achieving the goal of ensuring the stable operation of the power grid while reducing resource waste.

[0032] Another embodiment of the present invention provides a multi-port flexible interconnection control device, including: an acquisition module, a determination module, and a control module;

[0033] The acquisition module is used to acquire the first historical load information and real-time load information of the first flexible interconnection device, perform clustering based on the first historical load information to obtain several clustering results, and determine whether the first flexible interconnection device has failed based on each clustering result and the real-time load information.

[0034] The determining module is used to, if a fault occurs, acquire the second historical load information of each second flexible interconnect device, determine a number of backup devices in the second flexible interconnect device based on the second historical load information, calculate the target distance between the first flexible interconnect device and each of the backup devices, and determine the backup device with the smallest target distance as the target port flexible interconnect device, wherein the second flexible interconnect device is an adjacent device that is in a preset area and located in a different station area from the first flexible interconnect device.

[0035] The control module is used to connect the load and distributed power supply of the first flexible interconnect device to the target port flexible interconnect device, so that the target port flexible interconnect device can perform load scheduling.

[0036] This invention, by acquiring the first historical load information and real-time load information of the first flexible interconnect device, can comprehensively understand the device's load characteristics and current operating status. Clustering can promptly detect whether a fault has been detected in the device, facilitating rapid subsequent measures to prevent the fault from escalating and thus ensuring the stable operation of the power grid. In the event of a fault, by quickly determining the target port flexible interconnect device based on the historical load information and distance of surrounding devices, mutual support between devices can be achieved without adding additional backup equipment, reducing the impact of the fault on the power grid and minimizing resource waste. By connecting the load of the first flexible interconnect device and distributed power sources to the target port flexible interconnect device, it can be ensured that the area originally powered by the faulty first flexible interconnect device can still receive a stable power supply in the event of a fault, thereby ensuring the stable operation of the power grid. Compared with existing technologies, this application can ensure the stable operation of the power grid while reducing resource waste.

[0037] Furthermore, the determining module includes a first determining unit, a second determining unit, and a third determining unit:

[0038] The first determining unit is used to determine the corresponding load scheduling curve based on each of the clustering results and the first historical load information;

[0039] The second determining unit is used to determine whether the real-time load information conforms to the load scheduling curve. If it does not conform, it determines that the first flexible interconnect device has failed.

[0040] The third determining unit is used to calculate the vertical distance between the real-time load information and each of the clustering results if the conditions are met, and to determine that the first flexible interconnect device has malfunctioned if the vertical distance exceeds a preset threshold range.

[0041] This invention, by acquiring the first historical load information and real-time load information of the first flexible interconnect device, can comprehensively understand the device's load characteristics and current operating status. Clustering can promptly detect whether a fault has been detected in the device, facilitating rapid subsequent measures to prevent the fault from escalating and thus ensuring the stable operation of the power grid. In the event of a fault, by quickly determining the target port flexible interconnect device based on the historical load information and distance of surrounding devices, mutual support between devices can be achieved without adding additional backup equipment, reducing the impact of the fault on the power grid and minimizing resource waste. By connecting the load of the first flexible interconnect device and distributed power sources to the target port flexible interconnect device, it can be ensured that the area originally powered by the faulty first flexible interconnect device can still receive a stable power supply in the event of a fault, thereby ensuring the stable operation of the power grid. Compared with existing technologies, this application can ensure the stable operation of the power grid while reducing resource waste.

[0055] Multi-port flexible interconnection devices are crucial for the stable operation of the power grid and the continuity of power supply; a failure could lead to power outages in the distribution area. Existing technologies often equip each distribution area with backup equipment, which can maintain power supply during failures, but this increases costs and easily leads to resource waste.

[0056] See Figure 1 , Figure 1 This is a flowchart illustrating an embodiment of the multi-port flexible interconnection control method provided in this application. To ensure the stable operation of the power grid while reducing resource waste, an embodiment of the present invention provides a multi-port flexible interconnection control method, including steps S101 to S103.

[0057] Step S101: Obtain the first historical load information and real-time load information of the first flexible interconnection device, perform clustering based on the first historical load information to obtain several clustering results, and determine whether the first flexible interconnection device has failed based on each clustering result and the real-time load information.

[0058] In some embodiments, obtaining the first historical load information and real-time load information of the first flexible interconnect device specifically involves: accessing the software interface or programming interface (API) to find the first historical load information of the first flexible interconnect device within a preset time period, and obtaining the real-time load scheduling information of the first flexible interconnect device through a real-time monitoring system or SCADA system.

[0059] It should be noted that if accessing via a software interface, to find historical data reports or export functions, select the first flexible interconnect device and the first multi-port flexible interconnect device, and set the time range for querying. If using a programming interface (API), consult the relevant API documentation, use an appropriate method (such as a GET request) and include the necessary parameters (such as device ID, time range, etc.) to retrieve the data. Specific data retrieval methods are not the focus of this application and will not be elaborated upon here.

[0060] In some embodiments, clustering is performed based on the first historical load information to obtain several clustering results. Specifically, the first historical load information is first cleaned and preprocessed, including removing outliers, filling in missing values, and normalizing. For example, missing load values ​​are filled with the mean or median, and the load data is normalized to the range [0,1] to facilitate subsequent clustering analysis. Then, a suitable clustering algorithm is selected, such as K-means, DBSCAN, hierarchical clustering, etc., and clustering is performed using the first load information as the main feature. Clustering can also be performed by combining time features (such as load patterns in different time periods) and other relevant information. For example, load values ​​at different times within a day are used as feature vectors to analyze the clustering situation under different load patterns to obtain several clustering results.

[0061] It should be noted that each clustering result represents the amount of load to be scheduled under different conditions.

[0062] In some embodiments, determining whether the first flexible interconnect device has failed based on the clustering results and the real-time load information specifically involves: determining the corresponding load scheduling curve based on the clustering results and the first historical load information; determining whether the real-time load information conforms to the load scheduling curve; if not, determining that the first flexible interconnect device has failed; if so, calculating the vertical distance between the real-time load information and each clustering result; if the vertical distance exceeds a preset threshold range, determining that the first flexible interconnect device has failed. Specifically, firstly, the changing trend of the first historical load information corresponding to each cluster center is depicted to obtain multiple load scheduling curves, such as... Figure 2 As shown, for example, a load scheduling curve for a whole year or a month will be compiled. Then, the real-time load scheduling volume will be matched with the previously obtained load scheduling volume curve. If the real-time load information does not conform to the load scheduling volume change trend, it indicates that the historical load information of the first flexible interconnect device is abnormal and the first flexible interconnect device is judged to be faulty. If the real-time load information conforms to the load scheduling volume change trend, then the vertical distance between the real-time load information and each cluster center will be further calculated, and the minimum value among all vertical distances will be found. The minimum value will be compared with a preset threshold. If it is greater than or equal to the preset threshold range, it is determined that the first multi-port flexible interconnect device is faulty.

[0063] It should be noted that when determining whether real-time load information conforms to the load scheduling curve, it is necessary to calculate the deviation between the real-time load data and the load scheduling curve and set a threshold. If the deviation exceeds the threshold, the real-time data is considered not to conform to the curve.

[0064] It should be noted that the preset threshold can be set as needed, and this application does not impose any restrictions.

[0065] It should be noted that if the real-time load information of the first flexible interconnection device conforms to the load scheduling change trend, and the minimum distance between the real-time load information and each cluster center is less than a preset threshold, then it is determined that the first flexible interconnection device has not malfunctioned.

[0066] It should be noted that the load scheduling curve can more intuitively identify points where obvious anomalies occur (reducing the use of computing resources). At this point, rapid status confirmation can be achieved, and the flexible interconnect device can be switched in time. The first flexible interconnect device has been notified that it has failed and needs to be repaired in time. The clustering center exists to filter out less obvious anomalies (allocate computing resources to it), improve computing efficiency, and quickly determine whether a fault has occurred.

[0067] By promptly identifying whether the first flexible interconnection device has malfunctioned, it is convenient to take corresponding measures to switch to power supply from the normal device, ensuring the stability of the power supply in the distribution area and avoiding the waste of resources caused by setting up backup equipment.

[0068] Step S102: If a fault occurs, the second historical load information of each second flexible interconnect device is obtained, and several backup devices in the second flexible interconnect device are determined based on the second historical load information. The target distance between the first flexible interconnect device and each backup device is calculated, and the backup device with the smallest target distance is determined as the target port flexible interconnect device. The second flexible interconnect device is an adjacent device that is in a preset area and located in a different station area from the first flexible interconnect device.

[0069] In some embodiments, the second flexible interconnect device is an adjacent device located within a preset area but in a different substation than the first flexible interconnect device. Specifically, the process involves: acquiring the location information of the first flexible interconnect device and determining the preset area based on the location information; identifying several third flexible interconnect devices adjacent to the first flexible interconnect device from the preset area, and determining the substation range of each third flexible interconnect device; and filtering the third flexible interconnect devices according to the substation range to determine the second flexible interconnect device located in a different substation than the first flexible interconnect device. Specifically, if the first flexible interconnect device malfunctions, location information such as the geographic coordinates of the first flexible interconnect device is acquired through a positioning system or other positioning technology. A circular area is drawn with the obtained location information of the first flexible interconnect device as the center and a preset length as the radius, thereby determining the preset area containing the first flexible interconnect device. This preset area aims to delineate the range that may be associated with or influenced by the target device. Then, within the preset area, several third flexible interconnect devices adjacent to the first flexible interconnect device are identified based on information such as the layout and connection relationships of the devices. These adjacent devices have direct or indirect electrical connections or control relationships with the target device in the power system, and can influence or support each other to a certain extent. Based on the different substation division standards and ranges, the substation where each third flexible interconnection device is located within the preset area is marked. Finally, by comparing the substation markings of the third flexible interconnection devices with those of the first flexible interconnection devices, devices whose substations differ from those of the first flexible interconnection devices are selected from the third flexible interconnection devices and identified as second flexible interconnection devices.

[0070] It should be noted that a distribution area is a basic unit in a power system used to manage and divide power supply areas. Clearly defining the distribution area to which each device belongs helps with subsequent screening and dispatching decisions.

[0071] It should be noted that the terms "first," "second," and "third" do not indicate a sequential order. In the event of a fault, the first flexible interconnect device can be understood as the device that is faulty, the second flexible interconnect device is the device that is adjacent to the first flexible interconnect device within a preset area but in a different station area, and the third flexible interconnect device is the device that is adjacent to the first flexible interconnect device within the preset area.

[0072] This method of filtering by target area can minimize the distance between the third flexible interconnect device and the first flexible interconnect device, reduce line loss, and avoid resource waste. In this way, available devices located in different substations can be found in adjacent devices, so that load and power can be transferred or allocated when needed, ensuring the stability and reliability of power supply.

[0073] This method of selecting multi-port flexible interconnected devices that are adjacent to the target device but located in different distribution areas based on location information allows for rapid switching of load and power to suitable devices in nearby distribution areas when the target device fails, ensuring stable operation of the power grid and avoiding the need for dedicated backup equipment, thus reducing resource waste.

[0074] In some embodiments, if a fault occurs, the second historical load information of each second flexible interconnect device is obtained, and several backup devices among the second flexible interconnect devices are determined based on the second historical load information. Specifically, after determining each second multi-port flexible interconnect device, the second historical load information of the second flexible interconnect device in a preset time period is searched through a software interface or programming interface (API). Based on the second historical load information, the second flexible interconnect devices with higher load capacity (obtained by analyzing the second historical load information) are selected as candidates for backup devices. The load capacity may include indicators such as maximum load and load stability.

[0075] In some embodiments, the target distance between the first flexible interconnect device and each of the backup devices is calculated, and the backup device with the smallest target distance is determined as the target port flexible interconnect device. Specifically, the target distance between the first flexible interconnect device and each backup device is calculated based on the geographic coordinates using a geometric distance formula (such as Euclidean distance), and all calculated target distances are compared. The backup device with the smallest target distance is selected as the target port flexible interconnect device for receiving loads and distributed power.

[0076] It should be noted that load dispatch capability represents the control capability of a multi-port flexible interconnection device. In order to ensure the stable operation of the power grid, equipment with large load dispatch capability can be selected as backup support to ensure the stable operation of the power grid. The smaller the distance, the closer the two devices are in space, the smaller the line loss between the two devices, and the smaller the energy loss.

[0077] Step S103: Connect the load and distributed power supply of the first flexible interconnect device to the target port flexible interconnect device so that the target port flexible interconnect device can perform load scheduling.

[0078] In some embodiments, before connecting the load and distributed power supply of the first flexible interconnect device to the target port flexible interconnect device, the method further includes: determining the port types of the first flexible interconnect device and the target port flexible interconnect device respectively, and interconnecting the ports using corresponding cables according to the port types. Specifically, the device documentation of the first flexible interconnect device and the target port flexible interconnect device is consulted, and the device specifications provided by the manufacturer are reviewed. These specifications typically list the types of each port in detail (e.g., AC port, DC port, or mixed port). If the device documentation is unclear or unavailable, a site survey is conducted to determine the corresponding port types, and the corresponding cables are used for port interconnection according to the port types.

[0079] In some embodiments, the use of corresponding cables for port interconnection based on the port type specifically means: if the port type is an AC port, a three-phase AC cable is used for port interconnection; if the port type is a DC port, a DC cable is used for port interconnection; if the port type is a mixed AC / DC port, a three-phase AC cable and a DC cable are used for port interconnection. Specifically, if both devices have AC ports, a cable suitable for AC transmission, such as an AC power cable, is selected, ensuring that the cable's rated voltage and current capacity meet the device's AC output requirements. If both devices have DC ports, a DC cable, such as a DC power cord, is used for connection, again ensuring that the cable specifications match the device's DC output. If a mixed port connection is involved (i.e., one device is a DC port and the other is an AC port), the manufacturer's guidelines must be carefully consulted, as special mixed or combined cables may be required to meet different types of power transmission needs.

[0080] By determining the port type and using corresponding cables for interconnection, efficient and stable connections between various devices in the power grid are ensured to guarantee the stable operation of the power grid. At the same time, resource waste caused by mismatched port types or improper cable selection is avoided, thereby reducing the installation cost and achieving the goal of ensuring the stable operation of the power grid while reducing resource waste.

[0081] In some embodiments, connecting the load and distributed power supply of the first flexible interconnect device to the target port flexible interconnect device for load scheduling by the target port flexible interconnect device specifically involves: connecting the load and distributed power supply of the first flexible interconnect device to the target port flexible interconnect device, and re-scheduling the load and distributed power supply of the first flexible interconnect device according to a preset control method; if there is still a remaining load after the re-scheduling, the remaining load is allocated to the target distributed power supply of the target port flexible interconnect device itself. Specifically, when the first flexible interconnect device fails, it is necessary to reconnect the load and the output terminal of the distributed power supply it carries to the corresponding port of the target port flexible interconnect device, and re-schedule the load and distributed power supply according to a preset control method. This is generally based on factors such as real-time load demand, the output power of the distributed power supply, and the operating status of the power grid. For example, the distributed power supply is used first to meet the load demand, while balancing the power flow of each port to avoid overloading a certain port. After the re-scheduling, there may be a remaining load, i.e., load demand that cannot be fully met by the distributed power supply or other ports. At this time, the remaining load is allocated to the target distributed power supply of the target port flexible interconnect device itself.

[0082] In some embodiments, distributing the remaining load to the target distributed power source within the target port flexible interconnect device itself involves: first, assessing the remaining capacity and generation capability of the target distributed power source; and then, rationally allocating the remaining load based on its characteristics and priority. For example, critical loads may require priority allocation, ensuring the continuity and stability of their power supply.

[0083] This reload scheduling avoids power outages caused by faults, ensuring the continuity of power supply. Furthermore, if there is still remaining load after reload scheduling, it is allocated to the target distributed power source within the flexible interconnection device itself. This fully utilizes existing distributed power sources, avoiding resource idleness and waste, thus achieving the goal of ensuring stable grid operation while reducing resource waste.

[0084] This invention, by acquiring the first historical load information and real-time load information of the first flexible interconnect device, can comprehensively understand the device's load characteristics and current operating status. Clustering can promptly detect whether a fault has been detected in the device, facilitating rapid subsequent measures to prevent the fault from escalating and thus ensuring the stable operation of the power grid. In the event of a fault, by quickly determining the target port flexible interconnect device based on the historical load information and distance of surrounding devices, mutual support between devices can be achieved without adding additional backup equipment, reducing the impact of the fault on the power grid and minimizing resource waste. By connecting the load of the first flexible interconnect device and distributed power sources to the target port flexible interconnect device, it can be ensured that the area originally powered by the faulty first flexible interconnect device can still receive a stable power supply in the event of a fault, thereby ensuring the stable operation of the power grid. Compared with existing technologies, this application can ensure the stable operation of the power grid while reducing resource waste.

[0085] like Figure 3 As shown, based on the above method embodiments, corresponding apparatus embodiments are provided;

[0086] One embodiment of the present invention provides a multi-port flexible interconnection control device, including: an acquisition module 100, a determination module 200, and a control module 300;

[0087] The acquisition module 100 is used to acquire the first historical load information and real-time load information of the first flexible interconnection device, perform clustering based on the first historical load information to obtain several clustering results, and determine whether the first flexible interconnection device has failed based on each clustering result and the real-time load information.

[0088] The determining module 200 is used to, if a fault occurs, acquire the second historical load information of each second flexible interconnect device, determine a number of backup devices in the second flexible interconnect devices based on the second historical load information, calculate the target distance between the first flexible interconnect device and each of the backup devices, and determine the backup device with the smallest target distance as the target port flexible interconnect device, wherein the second flexible interconnect device is an adjacent device that is in a preset area and located in a different station area from the first flexible interconnect device;
