Description

Technical Field

[0001] This invention relates to the field of energy management technology, and in particular to a self-developed method and apparatus for launching a station-level microgrid control system. Background Technology

[0002] This section is intended to provide background or context for the embodiments of the invention set forth in the claims. The description herein is not an admission that it is prior art simply because it is included in this section.

[0003] With the continuous advancement of clean energy technologies, microgrid control systems integrating new energy sources have become a crucial tool for monitoring, scheduling, and managing power generation, grid, load, and energy storage. Their products have also become a core competitive advantage for relevant manufacturers. The implementation of microgrid control systems typically employs a three-layer architecture: cloud, edge, and terminal. The terminal layer deploys numerous sensors, data acquisition devices, and control devices. The edge layer uses communication gateways to aggregate, process, and convert data. To maintain stable operation of the local system and prevent cloud network communication interruptions, most manufacturers typically deploy rapid coordination and control devices at the local level, enabling rapid coordination and control of integrated energy resources. The cloud layer aggregates all data, enabling remote data presentation, operational monitoring, maintenance management, optimized scheduling, and predictive early warning functions. Through cloud, edge, and terminal integration, integrated energy resources become visible, controllable, and manageable.

[0004] However, the microgrid control system industry is relatively closed, with significant differences in implementation among various suppliers' systems, and open-source systems are virtually nonexistent. Customized development is often required depending on the specific project scenario, leading to long implementation cycles and high costs. To accelerate project implementation, energy companies often develop their own microgrid control systems tailored to their specific load operating characteristics. After testing and verification, these self-developed systems gradually replace external supplier systems, thus gradually forming products with core competitiveness.

[0005] When replacing a self-developed control system, technical challenges such as long technical links, large data acquisition, and numerous terminal devices are often encountered. If the external supplier's system is directly replaced, the reliability and security of the entire microgrid system will be affected. Therefore, there is an urgent need for a self-developed method to put a station-level microgrid control system into operation to solve the above difficulties. Summary of the Invention

[0006] This invention provides a method for launching a self-developed substation-level microgrid control system, which aims to achieve stable online operation of the system and ensure reliable and safe operation of the microgrid. The substation-level microgrid control system is used to manage the configuration and operation of resources within the microgrid, including source-grid-load-storage hardware. The method includes:

[0007] After the supplier's microgrid control system has been running stably for a preset period, the self-developed substation-level microgrid control system will be brought online for processing. A gray-scale adaptation layer is set between the source-grid-load-storage hardware and the two systems, allowing both systems to run simultaneously initially. The two systems include the supplier's microgrid control system and the self-developed substation-level microgrid control system. The gray-scale adaptation layer is used to: determine the correctness of the execution instructions of the self-developed substation-level microgrid control system based on the execution instructions of the supplier's microgrid control system; if the execution instructions of the self-developed substation-level microgrid control system are determined to be correct, the flow is switched from the supplier's microgrid control system to the self-developed substation-level microgrid control system; the flow is the data flow between the source-grid-load-storage hardware and the substation-level microgrid control system.

[0008] The flow between the source-grid-load-storage hardware and the self-developed station-level microgrid control system is gradually increased based on the gray-scale adaptation layer until all execution instructions of the supplier's microgrid control system are abandoned and the supplier's microgrid control system is taken offline.

[0009] This invention also provides a self-developed substation-level microgrid control system online device to achieve stable online operation of the self-developed substation-level microgrid control system and ensure the reliable and safe operation of the microgrid system. The substation-level microgrid control system is used to manage the configuration and operation of internal resources of the microgrid, including source-grid-load-storage hardware. The device includes:

[0010] The online operation module is used to bring the self-developed substation-level microgrid control system online after the supplier's microgrid control system has been running stably for a preset period of time. A gray-scale adaptation layer is set between the source-grid-load-storage hardware and the two systems, allowing both systems to run simultaneously initially. The two systems include the supplier's microgrid control system and the self-developed substation-level microgrid control system. The gray-scale adaptation layer is used to: determine the correctness of the execution instructions of the self-developed substation-level microgrid control system based on the execution instructions of the supplier's microgrid control system; if the execution instructions of the self-developed substation-level microgrid control system are determined to be correct, the flow is switched from the supplier's microgrid control system to the self-developed substation-level microgrid control system; the flow is the data flow between the source-grid-load-storage hardware and the substation-level microgrid control system.

[0011] The gray-scale strategy processing module is used to gradually increase the flow between the source-grid-load-storage hardware and the self-developed station-level microgrid control system based on the gray-scale adaptation layer, until all the execution instructions of the supplier's microgrid control system are abandoned and the supplier's microgrid control system is taken offline.

[0012] This invention also provides a computer device, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the above-described method for launching a research station-level microgrid control system.

[0013] This invention also provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the above-described method for launching a research station-level microgrid control system.

[0014] This invention also provides a computer program product, which includes a computer program that, when executed by a processor, implements the above-described method for launching a research and development station-level microgrid control system.

[0015] In this embodiment of the invention, a gray-scale deployment method is adopted to address the issue of safe and stable online operation of a self-developed microgrid control system. This method enables the self-developed microgrid control system to replace the external supplier system. By operating the dual systems simultaneously and using gray-scale adaptation layer control, concerns about the overall quality of the microgrid system under high reliability and high security requirements are alleviated. This achieves stable online operation of the self-developed site-level microgrid control system and ensures the reliable and safe operation of the microgrid system. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0023] The acquisition, transmission, storage, use, and processing of data in this application all comply with the relevant provisions of national laws and regulations.

[0024] To address the shortcomings of existing technologies, this invention aims to provide a method for the gradual rollout of a system, ensuring that the self-developed microgrid control system can gradually replace external systems and achieve stable system operation.

[0025] This invention addresses the challenge of gradually replacing existing systems while ensuring stable operation of self-developed microgrid control systems that consider new energy sources and have high requirements for reliability and safety. It provides gray-scale deployment measures such as gray-scale flow switching and full data comparison to ensure the smooth deployment of the self-developed system, rapid rollback upon problem detection, and thus guarantee the stable operation of the self-developed system.

[0026] Figure 1 This is a flowchart illustrating the method for launching a self-developed substation-level microgrid control system in an embodiment of the present invention. Figure 1 As shown, the method includes:

[0027] Step 101: After the supplier's microgrid control system has been running stably for a preset period of time, the self-developed substation-level microgrid control system is brought online for processing. A gray-scale adaptation layer is set between the source-grid-load-storage hardware and the two systems, with both systems initially running simultaneously. The two systems include the supplier's microgrid control system and the self-developed substation-level microgrid control system. The gray-scale adaptation layer is used to: determine the correctness of the execution instructions of the self-developed substation-level microgrid control system based on the execution instructions of the supplier's microgrid control system; when the execution instructions of the self-developed substation-level microgrid control system are determined to be correct, the flow is switched from the supplier's microgrid control system to the self-developed substation-level microgrid control system; the flow is the data flow between the source-grid-load-storage hardware and the substation-level microgrid control system.

[0028] Step 102: Gradually increase the flow between the source-grid-load-storage hardware and the self-developed station-level microgrid control system based on the grayscale adaptation layer until all execution instructions of the supplier's microgrid control system are abandoned and the supplier's microgrid control system is taken offline.

[0029] from Figure 1As can be seen from the process shown, the embodiments of the present invention realize the replacement of external supplier systems with self-developed microgrid control systems. By operating the dual systems simultaneously and using gray-scale adaptation layer control, concerns about the overall quality of the microgrid system under the requirements of high reliability and high security are alleviated. The self-developed station-level microgrid control system is stably put into operation, ensuring the reliable and safe operation of the microgrid system.

[0030] In this embodiment of the invention, the station-level microgrid control system is used to manage the configuration and operation of resources within the microgrid. These resources include, but are not limited to, source-grid-load-storage hardware and source-grid-load-storage terminals. The microgrid control system issues commands to the source-grid-load-storage hardware for execution.

[0031] Figure 2 This is a specific example diagram of the self-developed station-level microgrid control system online method in an embodiment of the present invention. Figure 2 This invention presents an overall flowchart of the method for launching a self-developed substation-level microgrid control system in an embodiment of the present invention. The following section combines... Figure 2 , Figure 1 To explain.

[0032] During implementation, the supplier's mature microgrid control system solution is first used to quickly deliver the microgrid control system and ensure the stable operation of the site-level microgrid.

[0033] In one embodiment, after the supplier's microgrid control system has been running stably for a preset period of time and before the self-developed site-level microgrid control system is put online for processing, the microgrid operation data of the supplier's microgrid control system is acquired; the microgrid operation data includes the input data and output data of the microgrid control system.

[0034] Preferably, obtaining microgrid operation data from the supplier's microgrid control system may include: obtaining microgrid operation data from the supplier's microgrid control system through the data aggregation interface of the supplier's microgrid control system or through source-grid-load-storage hardware; the data aggregation interface is used to receive and send microgrid operation data.

[0035] For example, by connecting through a source-grid-load-storage system with multiple power generation points or by interfacing with a supplier's microgrid control system (see reference). Figure 2 (Middle dashed line) Obtain microgrid operation data.

[0036] In a preferred embodiment, before the self-developed station-level microgrid control system is put online, the method further includes: using the microgrid operation data of the supplier's microgrid control system to verify the logical correctness of the self-developed station-level microgrid control system.

[0037] At this point, a verification and comparison test is performed in the test environment.

[0038] Preferably, verifying the logical correctness of the self-developed site-level microgrid control system using microgrid operation data from the supplier's microgrid control system may include:

[0039] The microgrid operation data of the supplier's microgrid control system is written into the first instruction result data table; the first instruction result data table includes multiple instruction result data; each instruction result data includes a first input parameter, a first output parameter, and a unique identifier for that instruction result data;

[0040] Multiple test instructions are generated based on the first instruction result data table; each test instruction includes a second input parameter and a unique identifier for that test instruction; wherein the unique identifier of the test instruction corresponds one-to-one with the unique identifier of the instruction result data;

[0041] The second input parameter from multiple test commands is input into the self-developed station-level microgrid control system, which outputs multiple second output parameters.

[0042] Using the unique identifier of the test command and the unique identifier of the command result data, the second output parameter is compared with the first output parameter in turn;

[0043] Based on the comparison results, the logical correctness of the self-developed station-level microgrid control system was verified.

[0044] Figure 3 This is a flowchart illustrating the verification of the functional logic of the self-developed microgrid control system in an embodiment of the present invention. (Refer to...) Figure 3 This invention implements all functions of a self-developed microgrid control system at the site level and deploys it in a test environment. Data comparison with the supplier's microgrid control system verifies the correctness of the self-developed microgrid control system's functional logic. (Reference) Figure 3 :

[0045] (1) The supplier's microgrid control system issues control commands (write traffic) to the terminal source-grid-load-storage system for execution;

[0046] (2) During the distribution process, the input and output parameters of this execution are recorded synchronously and written into the instruction result data table. Each data item forms a ticketNo, marking the uniqueness of this record.

[0047] (3) The self-developed microgrid system reads the input parameters from the command result data;

[0048] (4) The self-developed microgrid system also accepts user-defined input parameters;

[0049] (5) The self-developed microgrid system processes data according to business logic and generates output parameters;

[0050] (6) The generated output parameters are compared with the instruction result data output parameters in step (2);

[0051] (7) The comparison results are stored in the database and the log is printed.

[0052] The self-developed microgrid continuously retrieves command result data, calculates the input parameter data, compares the parameter results, and stores the comparison results in a database. Inconsistent results can be periodically retrieved through computer programs or manually for troubleshooting, ensuring the consistency between the logic implemented in the self-developed system and the logic implemented in the external supplier's system.

[0053] In one embodiment, the logical correctness of the self-developed station-level microgrid control system is verified based on the comparison results, including:

[0054] When there is a difference between the second output parameter and the first output parameter, the logic function of the self-developed station-level microgrid control system is adjusted and verified according to the difference.

[0055] If there is no difference between the second output parameter and the first output parameter, the logic correctness verification of the self-developed station-level microgrid control system is confirmed to be successful.

[0056] Step 101 may include: once the logic correctness verification of the self-developed station-level microgrid control system passes, the self-developed station-level microgrid control system will be put online for processing.

[0057] In this embodiment of the invention, a grayscale adaptation layer is set between the source-grid-load-storage hardware and the dual systems, with both systems initially operating simultaneously. The dual systems include a supplier's microgrid control system and a self-developed site-level microgrid control system. The grayscale adaptation layer is used to: determine the correctness of the execution instructions of the self-developed site-level microgrid control system based on the execution instructions of the supplier's microgrid control system; when the execution instructions of the self-developed site-level microgrid control system are determined to be correct, the flow is switched from the supplier's microgrid control system to the self-developed site-level microgrid control system; the flow is the data flow between the source-grid-load-storage hardware and the site-level microgrid control system.

[0058] The two systems control flow is switched through a grayscale adaptation layer. Finally, based on the grayscale adaptation layer, the flow between the source-grid-load-storage hardware and the self-developed station-level microgrid control system is gradually increased until all the execution instructions of the supplier's microgrid control system are abandoned and the supplier's microgrid control system is taken offline.

[0059] Preferably, the grayscale adaptation layer is specifically used for: comparing the execution instructions of the supplier's microgrid control system and the execution instructions of the self-developed substation-level microgrid control system; if they are consistent, discarding the execution instructions of the supplier's microgrid control system and transmitting the execution instructions of the self-developed substation-level microgrid control system to the source-grid-load-storage hardware; if they are inconsistent, discarding the execution instructions of the self-developed microgrid control system and transmitting the execution instructions of the supplier's substation-level microgrid control system to the source-grid-load-storage hardware.

[0060] In a preferred embodiment, after the logic correctness verification of the self-developed substation-level microgrid control system passes and the self-developed substation-level microgrid control system is put online, the method may further include:

[0061] Construct a bypass comparison logic system; the bypass comparison logic system is used to maintain the command execution of the self-developed station-level microgrid control system.

[0062] By using bypass comparison logic, potential faults and problems can be detected in a timely manner, thereby improving the reliability of the entire system.

[0063] In one embodiment, gradually increasing the flow between the source-grid-load-storage hardware and the self-developed site-level microgrid control system based on the grayscale adaptation layer until all execution instructions of the supplier's microgrid control system are abandoned can include:

[0064] The execution process of the dual systems is recorded as a log;

[0065] Periodically retrieve the execution process comparison results of the two systems from the logs;

[0066] Based on the comparison results, an adjustment strategy is determined. The adjustment strategy includes increasing the gray-scale configuration flow and flow rollback. Increasing the gray-scale configuration flow means increasing the flow between the source-grid-load-storage hardware and the self-developed station-level microgrid control system. Flow rollback means rolling back to a specified time point and reducing the flow between the source-grid-load-storage hardware and the self-developed station-level microgrid control system.

[0067] Figure 4 This is another specific example diagram of the self-developed field station-level microgrid control system online method in the embodiments of the present invention, as shown in the figure. Figure 4 As shown, the self-developed substation-level microgrid control system has been deployed in a production environment. Above the source-grid-load-storage execution layer, a gray-scale adaptation layer handles the switching of control flow between the two systems. The microgrid system reads the gray-scale configuration and sends it to the gray-scale adaptation layer. The gray-scale adaptation layer reads the gray-scale flags and determines whether to execute or discard the command. (Reference) Figure 4 :

[0068] (1) The supplier's microgrid control system sends control commands (write traffic) to the local grayscale adaptation layer for execution;

[0069] (2) During the distribution process, the input and output parameters of this execution are recorded synchronously and written to the instruction result log table. Each data item forms a ticketNo, marking the uniqueness of this record;

[0070] (3) The self-developed microgrid control system reads the system grayscale configuration, obtains the input parameters according to the write flow switching ratio, and calculates the execution results;

[0071] (4) The self-developed microgrid control system will send the execution results and grayscale flow identifier to the grayscale adaptation layer;

[0072] (5) The self-developed microgrid control system bypasses and compares the settlement results of this instruction;

[0073] (6) The comparison results with the supplier's microgrid control system are stored in the database and the comparison log is recorded for subsequent statistical investigation by engineers.

[0074] (7) The grayscale adaptation layer receives the execution instructions from the self-developed microgrid control system and compares them with the microgrid control instructions from the supplier. If they match, the self-developed microgrid system instructions are executed and the supplier's microgrid control system instructions are discarded; if they do not match, the supplier's microgrid control system instructions are executed and the self-developed microgrid system instructions are discarded.

[0075] (8) Record execution logs, and compare the command results with the logs by computer program or manual timed pull. Based on the comparison results, decide whether to increase the gray-scale configuration traffic or roll back the traffic to ensure the stable operation of the system.

[0076] In summary, for reference Figure 2 In terms of replacing the self-developed microgrid control system, the embodiments of the present invention generally follow the following steps: the self-developed station-level microgrid control system is put into operation.

[0077] Step 1: Supplier System Operation. Leveraging the supplier's mature solutions, the microgrid control system is delivered quickly, ensuring the stable operation of the site-level microgrid.

[0078] Step 2: Dual-system operation, with the self-developed system only monitoring and not controlling. Microgrid operation data is obtained through point-to-multipoint generation from the power source, grid, load, and storage system, or by connecting to the supplier's microgrid control system (dashed line). The upper-level functions of the microgrid control system are replicated based on this data. The logical correctness is verified by writing a comparison program and manually verifying the output.

[0079] Step 3: Dual-system operation, canary traffic verification of the self-developed system. After functional verification is successful, canary traffic switching is implemented. A canary strategy is formulated through dual-system coordination (dashed line). For specific strategies, refer to steps 103 and 104. Figure 4 Gradually increase the volume in the grayscale phase and develop a traffic rollback plan.

[0080] Step 4: The self-developed system is put into operation, and the supplier's system is taken offline, achieving complete replacement of the self-developed system.

[0081] This invention addresses the issue of ensuring the safe and stable operation of a self-developed microgrid control system by employing a gray-scale deployment method to replace external supplier systems. The logic of the self-developed microgrid control system is verified through dual-system construction, full data comparison, gray-scale flow switching, bypass data comparison, and flow rollback. This resolves concerns about system quality under high reliability and high security requirements for self-developed microgrid systems.

[0082] The method described in this invention has enabled the complete replacement of a supplier's system in a certain power plant microgrid project with a self-developed microgrid system. This ensures stable system operation and also establishes the product's own competitiveness and advantages.

[0083] This invention also provides a self-developed field-level microgrid control system online device, as described in the following embodiments. Since the principle by which this device solves the problem is similar to the self-developed field-level microgrid control system online method, the implementation of this device can refer to the implementation of the self-developed field-level microgrid control system online method; repeated details will not be elaborated further.

[0084] Figure 5 This is a schematic diagram of the self-developed station-level microgrid control system online device in an embodiment of the present invention, as shown below. Figure 5 As shown, the device 500 is a substation-level microgrid control system used to manage the configuration and operation of resources within the microgrid. These resources include source-grid-load-storage hardware. The device 500 includes:

[0085] The online operation module 501 is used to bring the self-developed substation-level microgrid control system online after the supplier's microgrid control system has been running stably for a preset period of time. A gray-scale adaptation layer is set between the source-grid-load-storage hardware and the two systems, allowing both systems to run simultaneously initially. The two systems include the supplier's microgrid control system and the self-developed substation-level microgrid control system. The gray-scale adaptation layer is used to: determine the correctness of the execution instructions of the self-developed substation-level microgrid control system based on the execution instructions of the supplier's microgrid control system; when the execution instructions of the self-developed substation-level microgrid control system are determined to be correct, the flow is switched from the supplier's microgrid control system to the self-developed substation-level microgrid control system; the flow is the data flow between the source-grid-load-storage hardware and the substation-level microgrid control system.

[0086] The gray-scale strategy processing module 502 is used to gradually increase the flow between the source-grid-load-storage hardware and the self-developed station-level microgrid control system based on the gray-scale adaptation layer until all execution instructions of the supplier's microgrid control system are abandoned and the supplier's microgrid control system is taken offline.

[0087] In one embodiment, the device 500 may further include a supplier system operation data acquisition module and a test environment verification module.

[0088] The supplier system operation data acquisition module is used to acquire the microgrid operation data of the supplier's microgrid control system before the self-developed station-level microgrid control system is put online and processed by the online operation module 501.

[0089] The test environment verification module is used to: verify the logical correctness of the self-developed site-level microgrid control system using microgrid operation data from the supplier's microgrid control system;

[0090] The online operation module 501 is specifically used to: when the logic correctness verification of the self-developed station-level microgrid control system passes, process the self-developed station-level microgrid control system to go online.

[0091] In one embodiment, the supplier system operation data acquisition module is specifically used to: acquire microgrid operation data of the supplier microgrid control system through the data aggregation interface of the supplier microgrid control system or through source-grid-load-storage hardware; the data aggregation interface is used to receive and send microgrid operation data.

[0092] In one embodiment, the test environment verification module is specifically used for:

[0093] The microgrid operation data of the supplier's microgrid control system is written into the first instruction result data table; the first instruction result data table includes multiple instruction result data; each instruction result data includes a first input parameter, a first output parameter, and a unique identifier for that instruction result data;

[0094] Multiple test instructions are generated based on the first instruction result data table; each test instruction includes a second input parameter and a unique identifier for that test instruction; wherein the unique identifier of the test instruction corresponds one-to-one with the unique identifier of the instruction result data;

[0095] The second input parameter from multiple test commands is input into the self-developed station-level microgrid control system, which outputs multiple second output parameters.

[0096] Using the unique identifier of the test command and the unique identifier of the command result data, the second output parameter is compared with the first output parameter in turn;

[0097] Based on the comparison results, the logical correctness of the self-developed station-level microgrid control system was verified.

[0098] In one embodiment, the test environment verification module is specifically used for:

[0099] When there is a difference between the second output parameter and the first output parameter, the logic function of the self-developed station-level microgrid control system is adjusted and verified according to the difference.

[0100] If there is no difference between the second output parameter and the first output parameter, the logic correctness verification of the self-developed station-level microgrid control system is confirmed to be successful.

[0101] In one embodiment, the grayscale adaptation layer is specifically used for:

[0102] Compare the execution commands of the supplier's microgrid control system with the execution commands of the self-developed site-level microgrid control system;

[0103] If they match, discard the execution instructions of the supplier's microgrid control system and transmit the execution instructions of the self-developed station-level microgrid control system to the source-grid-load-storage hardware;

[0104] If there is a discrepancy, the execution instructions of the self-developed microgrid control system are discarded, and the execution instructions of the supplier's site-level microgrid control system are transmitted to the source-grid-load-storage hardware.

[0105] In one embodiment, the device 500 further includes a bypass comparison logic module.

[0106] The bypass comparison logic module is used to construct the bypass comparison logic system after the online operation module 501 processes the self-developed station-level microgrid control system online; the bypass comparison logic system is used to maintain the instruction execution of the self-developed station-level microgrid control system.

[0107] In one embodiment, the grayscale strategy processing module 502 is specifically used for:

[0108] The execution process of the dual systems is recorded as a log;

[0109] Periodically retrieve the execution process comparison results of the two systems from the logs;

[0110] Based on the comparison results, an adjustment strategy is determined. The adjustment strategy includes increasing the gray-scale configuration flow and flow rollback. Increasing the gray-scale configuration flow means increasing the flow between the source-grid-load-storage hardware and the self-developed station-level microgrid control system. Flow rollback means rolling back to a specified time point and reducing the flow between the source-grid-load-storage hardware and the self-developed station-level microgrid control system.

[0111] This invention also provides a computer device, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the above-mentioned method for launching the self-developed station-level microgrid control system.

[0113] This invention also provides a computer program product, which includes a computer program that, when executed by a processor, implements the above-described method for launching a self-developed microgrid control system at the field station level.

[0114] This invention enables a self-developed microgrid control system to replace an external supplier's system. After the logical correctness verification of the self-developed site-level microgrid control system is passed, the simultaneous operation of the two systems and the gray-scale adaptation layer control alleviate concerns about the overall quality of the microgrid system under the high reliability and high security requirements of the self-developed microgrid system. This achieves stable online operation of the self-developed site-level microgrid control system and ensures the reliable and safe operation of the microgrid system.
