Description

Technical Field

[0001] This application relates to the field of smart grid technology, and in particular to a method, apparatus, computer equipment, storage medium and computer program product for coordinated control of multiple dispatching commands. Background Technology

[0002] With the increasing trend of cross-regional interconnection of power dispatching systems, power grid dispatching technology is gradually evolving from independent dispatching in a single region to multi-regional collaborative dispatching. The most critical aspect of executing multi-dispatch collaborative control is how to coordinate multiple dispatching commands across regions.

[0003] When switching the dispatch and operation modes of power plants, the process often relies on manual assessment of the grid status and manual triggering of the mode switching operation. However, manual intervention is slow to respond and cannot quickly deal with emergencies such as sudden changes in grid frequency, resulting in low efficiency in switching the dispatch and operation modes of power plants. Summary of the Invention

[0004] Therefore, it is necessary to provide a multi-dispatch instruction collaborative control method, device, computer equipment, computer-readable storage medium, and computer program product that can improve the efficiency of power plant operation mode switching, in order to address the above-mentioned technical problems.

[0005] Firstly, this application provides a method for coordinated control of multiple scheduling instructions. The method includes:

[0006] The system receives current dispatch instructions issued by at least two power dispatching systems for the power plant, and obtains the current grid status information of the power plant; the current dispatch instructions carry corresponding current dispatching demand information.

[0007] If the current power grid status information meets the preset power grid status conditions, then the current operating mode of the power plant is determined based on the current demand overlap between at least two current dispatch demand information.

[0008] Upon receiving updated dispatch instructions issued by at least two power dispatch systems for the power plant, the updated dispatch demand information carried in the at least two updated dispatch instructions is subjected to demand overlap analysis to obtain the updated demand overlap between the at least two updated dispatch demand information.

[0009] Based on the current demand overlap and the updated demand overlap, the current operating mode is updated to obtain the updated operating mode of the power plant.

[0010] Based on the updated operating mode, power dispatching is performed on the power plant to obtain the power dispatching results of the power plant.

[0011] In one embodiment, based on the current demand overlap and the updated demand overlap, the current operating mode is updated to obtain the updated operating mode of the power plant, including:

[0012] Based on the overlap difference between the current demand overlap and the updated demand overlap, the overlap change information of the updated demand overlap is obtained;

[0013] If the detected overlap change information meets the preset overlap change conditions, then the current operating mode is updated to obtain the updated operating mode of the power plant.

[0024] If the current demand overlap is greater than or equal to the first overlap threshold, then the plant combination mode is determined as the current operating mode of the power plant.

[0025] If the current demand overlap is less than or equal to the second overlap threshold, then the branch plant mode is determined as the current operating mode of the power plant.

[0026] In one embodiment, based on the updated operating mode, power dispatching processing is performed on the power plant to obtain the power dispatching result of the power plant, including:

[0027] If the updated operating mode represents the combined plant mode, then according to at least two updated scheduling demand information and the weights corresponding to each of the power dispatching systems, the generating units of the power plant are jointly dispatched and allocated to obtain the combined plant scheduling allocation result of the generating units. Based on the combined plant scheduling allocation result, the generating units are controlled to perform power dispatching processing to obtain the power dispatching result of the power plant.

[0028] If the updated operating mode represents the branch plant mode, then based on at least two updated scheduling demand information, the generating units of the power plant are independently scheduled and allocated to obtain the branch plant scheduling allocation result of the generating units. Based on the branch plant scheduling allocation result, the generating units are controlled to perform power scheduling processing to obtain the power scheduling result of the power plant.

[0029] Secondly, this application also provides a multi-scheduling instruction cooperative control device. The device includes:

[0037] If the current power grid status information meets the preset power grid status conditions, then the current operating mode of the power plant is determined based on the current demand overlap between at least two current dispatch demand information.

[0038] Upon receiving updated dispatch instructions issued by at least two power dispatch systems for the power plant, the updated dispatch demand information carried in the at least two updated dispatch instructions is subjected to demand overlap analysis to obtain the updated demand overlap between the at least two updated dispatch demand information.

[0039] Based on the current demand overlap and the updated demand overlap, the current operating mode is updated to obtain the updated operating mode of the power plant.

[0040] Based on the updated operating mode, power dispatching is performed on the power plant to obtain the power dispatching results of the power plant.

[0041] Fourthly, this application also provides a computer-readable storage medium. The computer-readable storage medium stores a computer program thereon, which, when executed by a processor, performs the following steps:

[0042] The system receives current dispatch instructions issued by at least two power dispatching systems for the power plant, and obtains the current grid status information of the power plant; the current dispatch instructions carry corresponding current dispatching demand information.

[0043] If the current power grid status information meets the preset power grid status conditions, then the current operating mode of the power plant is determined based on the current demand overlap between at least two current dispatch demand information.

[0044] Upon receiving updated dispatch instructions issued by at least two power dispatch systems for the power plant, the updated dispatch demand information carried in the at least two updated dispatch instructions is subjected to demand overlap analysis to obtain the updated demand overlap between the at least two updated dispatch demand information.

[0045] Based on the current demand overlap and the updated demand overlap, the current operating mode is updated to obtain the updated operating mode of the power plant.

[0046] Based on the updated operating mode, power dispatching is performed on the power plant to obtain the power dispatching results of the power plant.

[0047] Fifthly, this application also provides a computer program product. The computer program product includes a computer program that, when executed by a processor, performs the following steps:

[0048] The system receives current dispatch instructions issued by at least two power dispatching systems for the power plant, and obtains the current grid status information of the power plant; the current dispatch instructions carry corresponding current dispatching demand information.

[0049] If the current power grid status information meets the preset power grid status conditions, then the current operating mode of the power plant is determined based on the current demand overlap between at least two current dispatch demand information.

[0051] Based on the current demand overlap and the updated demand overlap, the current operating mode is updated to obtain the updated operating mode of the power plant.

[0052] Based on the updated operating mode, power dispatching is performed on the power plant to obtain the power dispatching results of the power plant.

[0053] The aforementioned multi-dispatch instruction collaborative control method, device, computer equipment, storage medium, and computer program product receive current dispatch instructions issued by at least two power dispatching systems for a power plant, and acquire the power plant's current grid status information. The current dispatch instructions carry corresponding current dispatch demand information. If the current grid status information meets preset grid status conditions, the current operating mode of the power plant is determined based on the current demand overlap between the at least two current dispatch demand information. Upon receiving updated dispatch instructions issued by at least two power dispatching systems for the power plant, demand overlap analysis is performed on the updated dispatch demand information carried in the at least two updated dispatch instructions to obtain the updated demand overlap between the at least two updated dispatch demand information. Based on the current demand overlap and the updated demand overlap, the current operating mode is updated to obtain the updated operating mode of the power plant. Based on the updated operating mode, power dispatch processing is performed on the power plant to obtain the power dispatch result of the power plant. This method intelligently determines the current operating mode of a power plant based on the demand overlap between dispatch instructions issued by multiple power dispatching systems when the current grid status information of the power plant meets the grid status conditions. When dispatch instructions are updated, the updated demand overlap between the updated dispatch instructions is dynamically analyzed and compared with the current overlap, thereby adaptively updating and optimizing the operating mode of the power plant. This method effectively solves the problems of difficulty in coordinating multi-source dispatch instructions and instruction delay or conflict during mode switching. It enables power plants to quickly and accurately switch and dynamically coordinate operating modes in multi-dispatch collaborative control scenarios, thereby improving the efficiency of power plant operating mode switching and also helping to improve the real-time performance, flexibility, and operational safety and stability of power dispatching.

[0060] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0061] It should be noted that the terms "first," "second," etc., used in this application can be used to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish the first element from the second element. The terms "comprising" and "having," and any variations thereof, used in this application, are intended to cover non-exclusive inclusion. The term "multiple" used in this application refers to two or more. The term "and / or" used in this application refers to one of the embodiments, or any combination of multiple embodiments.

[0062] In one embodiment, such as Figure 1 As shown, a multi-scheduling command collaborative control method is provided. This embodiment illustrates the application of this method to an Automatic Generation Control (AGC) system, where the AGC system refers to an automated system in a power plant used for real-time monitoring and adjustment of generator output. It is understood that this method can also be applied to terminals, servers, or systems including both terminals and servers, and is implemented through interaction between the terminals and servers. In this embodiment, the method includes the following steps:

[0063] Step S101: Receive current dispatch instructions issued by at least two power dispatch systems for the power plant, and obtain the current grid status information of the power plant; the current dispatch instructions carry the corresponding current dispatch demand information.

[0064] In this context, a power dispatching system refers to a dispatching agency with power dispatching authority. At least two power dispatching systems can belong to dispatching agencies in different regions, at different levels, or with different jurisdictions. For example, a power dispatching system may include a first power dispatching system and a second power dispatching system, where the first power dispatching system is located in area A, and the second power dispatching system is located in area B.

[0065] Specifically, at least two power dispatching systems encapsulate the dispatching demand information for the power plant into dispatching instructions and issue them to the power plant. The power plant's AGC system receives the dispatching instructions currently issued by each power dispatching system and marks them as the current dispatching instructions. The AGC system can also collect the current grid status information of the power plant in real time through the Supervisory Control and Data Acquisition (SCADA) system.

[0066] The current power grid status information refers to information describing the operating status of a power plant in the current time period. For example, the current power grid status information includes the total number of incoming and outgoing circuits, the circuit breaker closing status (all circuit breakers must be closed for combined plants, and area circuit breakers must be open for branch plants), and the switch closing status.

[0067] Step S102: If the current power grid status information meets the preset power grid status conditions, then the current operating mode of the power plant is determined based on the current demand overlap between at least two current dispatch demand information.

[0068] Among them, the power grid status condition refers to the condition for determining whether the current power grid status information meets the requirements for switching the operation mode.

[0069] Specifically, the AGC system can first determine whether to switch operating modes or lock operating modes based on the current grid status information. If the current grid status information does not meet the preset grid status conditions, the operating mode is locked, and the AGC system locks the power plant's current operating mode for a period of time, or locks the power plant's current operating mode until the preset grid status conditions are met. If the current grid status information meets the preset grid status conditions, the operating mode can be switched. The AGC system then calculates the current demand overlap between at least two current dispatch demand information sets and determines the power plant's current operating mode based on the current demand overlap.

[0070] Step S103: Upon receiving updated dispatch instructions issued by at least two power dispatch systems for the power plant, perform demand overlap analysis on the updated dispatch demand information carried in the at least two updated dispatch instructions to obtain the updated demand overlap between the at least two updated dispatch demand information.

[0071] Among them, the overlap of updated requirements refers to the proportion of repeated requirements among multiple updated scheduling requirements.

[0072] Specifically, at least two power dispatching systems can continue to issue dispatching instructions to power plants. The AGC system marks newly received dispatching instructions as updated dispatching instructions, and then performs demand overlap analysis on the updated dispatching demand information carried in at least two updated dispatching instructions. That is, it analyzes the proportion of demand overlap between at least two updated dispatching demand information, for example, by comparing the proportion of the same parameters to obtain the updated demand overlap between at least two updated dispatching demand information. Similarly, the AGC system can also perform demand overlap analysis on the current dispatching demand information in at least two current dispatching instructions to obtain the current demand overlap between at least two current dispatching demand information.

[0073] Step S104: Based on the current demand overlap and the updated demand overlap, perform mode update processing on the current operating mode to obtain the updated operating mode of the power plant.

[0074] Specifically, the AGC system calculates the overlap change information based on the current demand overlap and the updated demand overlap; it uses the overlap change information as the basis for judging the mode update process to determine the updated operation mode of the power plant.

[0075] Step S105: Based on the updated operating mode, perform power dispatching processing on the power plant to obtain the power dispatching results of the power plant.

[0076] Specifically, the AGC system takes corresponding power dispatching measures for the power plant based on the updated operating mode (such as combined plant mode or branch plant mode), and finally obtains the power dispatching results of the power plant.

[0077] In the aforementioned multi-dispatch command collaborative control method, when the current grid state information of the power plant meets the grid state conditions, the current operating mode of the power plant is intelligently determined based on the demand overlap between dispatch commands issued by multiple power dispatching systems. When the dispatch commands are updated, the updated demand overlap between the updated dispatch commands is dynamically analyzed and compared with the current overlap, thereby adaptively updating and optimizing the operating mode of the power plant. This method effectively solves the problems of difficulty in coordinating multi-source dispatch commands and command delays or conflicts during mode switching. It enables the power plant to quickly and accurately switch and dynamically coordinate its operating mode in multi-dispatch collaborative control scenarios, thereby improving the efficiency of power plant operating mode switching and also helping to improve the real-time performance, flexibility, and operational safety and stability of power dispatching.

[0078] In one embodiment, such as Figure 2 As shown, step S104 above updates the current operating mode based on the current demand overlap and the updated demand overlap, resulting in the updated operating mode of the power plant. This update includes the following:

[0079] Step S201: Obtain the overlap change information of the updated demand overlap based on the overlap difference between the current demand overlap and the updated demand overlap.

[0080] Specifically, the AGC system calculates the difference between the current demand overlap and the updated demand overlap to obtain the overlap difference value, and sets the absolute value of the overlap difference value as the overlap change information of the updated demand overlap.

[0081] Step S202: If the detected overlap change information meets the preset overlap change conditions, then the current operating mode is updated to obtain the updated operating mode of the power plant.

[0082] Among them, the overlap change condition refers to the judgment condition used to determine whether the overlap change is drastic. For example, the overlap change condition can be to determine whether the overlap change information exceeds a preset overlap change threshold.

[0083] Specifically, if the detected overlap change information exceeds a preset overlap change threshold, the current operating mode is updated. This can involve switching the current operating mode to another operating mode, thus obtaining the updated operating mode of the power plant. For example, if the current operating mode is a branch plant mode, the updated operating mode is a combined plant mode; conversely, if the current operating mode is a combined plant mode, the updated operating mode is a branch plant mode.

[0084] In this embodiment, by calculating the overlap difference between the current and updated demand overlap, dynamic overlap change information can be obtained in real time. When this overlap change information meets preset overlap change conditions, the power plant's current operating mode is automatically and adaptively updated. This mechanism effectively achieves rapid perception and accurate response to changes in multi-source scheduling demands, enabling the power plant to adjust its operating strategy in a timely manner based on the dynamic coordination of scheduling instructions. This improves the efficiency of power plant operating mode switching while ensuring the timeliness and rationality of mode switching.

[0085] In one embodiment, step S202 above, which updates the current operating mode to obtain the updated operating mode of the power plant, specifically includes the following: generating a mode switching message based on the current operating mode, and sending the mode switching message to at least two power dispatching systems respectively; the mode switching message is used to instruct at least two power dispatching systems to stop issuing dispatching instructions in the future time period; adjusting the power plant's load, circuit breaker, and load in sequence to obtain the adjusted power plant; and performing mode switching on the current operating mode to obtain the updated operating mode of the adjusted power plant.

[0086] In this context, "future time period" refers to a period of time in the future. For example, a future time period could be the next 5 minutes, 30 minutes, or 1 hour.

[0087] When the overlap change information meets the preset overlap change conditions (e.g., the required overlap decreases from 40% to 5%), and the current operating mode is updated, the AGC system executes the following three stages:

[0088] (1) Pre-switching phase: Based on the current operating mode, generate a mode switching message; send the mode switching message to each power dispatching system 10 seconds in advance, that is, give advance notice to each power dispatching system that the power plant's operating mode is about to be switched, so that each power dispatching system will stop issuing dispatching instructions in the future time period and simultaneously freeze unnecessary load adjustment instructions.

[0089] (2) Switching execution phase: First, adjust the load of the power plant unit to a safe range (e.g., reduce it to 90% of the target value), then open / close the circuit breaker (millisecond-level operation), and then restore the load to the target value. That is, operate in the order of "load → circuit breaker → load" in sequence, and also avoid the frequency fluctuation of the power plant exceeding the target frequency fluctuation threshold (e.g., 0.1Hz) during the switching process; finally, the updated operation mode of the power plant after adjustment is obtained.

[0090] (3) Post-switch adaptation: Automatically update the dispatch instruction receiving logic. For example, when the updated operating mode is the combined plant mode, it receives dispatch instructions jointly controlled by multiple power dispatch systems. When the updated operating mode is the branch plant mode, it receives dispatch instructions independently controlled by each power dispatch system.

[0091] In this embodiment, by generating and sending mode switching messages to each power dispatching system before mode switching, the system can suspend issuing dispatching instructions in the future period, providing a stable operating window for internal adjustments within the power plant. Subsequently, the system sequentially adjusts the power plant's load, circuit breakers, and loads in an orderly manner, ultimately completing a smooth switch of operating modes. This effectively avoids equipment conflicts or operational risks caused by external instruction interference during mode switching, ensuring the safety and controllability of the switching operation, and significantly improving the reliability of power plant operating mode switching and the stability of multi-dispatch collaborative control.

[0092] In one embodiment, the current grid status information includes the current grid frequency. After obtaining the current grid status information of the power plant in step S101, the method further includes: obtaining the grid frequency fluctuation value of the power plant based on the frequency difference between the current grid frequency and the historical grid frequency of the power plant; if the grid frequency fluctuation value is greater than a preset fluctuation threshold, then locking the plant merging mode as the current operating mode of the power plant.

[0093] Historical grid frequency refers to the grid frequency most recent in time from the current grid frequency. For example, historical grid frequency could be the grid frequency at the previous point in time.

[0094] Specifically, the AGC system acquires the power plant's historical grid frequency, calculates the difference between the current grid frequency and the historical grid frequency in the current grid status information, and thus obtains the grid frequency fluctuation value. If the grid frequency fluctuation value is greater than a preset fluctuation threshold (e.g., grid frequency fluctuation value > 0.2Hz), the AGC system can lock the plant's combined operation mode as the power plant's current operating mode, avoiding frequent switching of operating modes and improving the stability of power plant operation.

[0095] In this embodiment, the power grid frequency fluctuation value is obtained by calculating the frequency difference between the current power grid frequency (e.g., 500kV / 18kV) and the historical power grid frequency. When the power grid frequency fluctuation value exceeds the preset fluctuation threshold, the power plant's combined operation mode is locked to the current operation mode. This mechanism effectively enhances the power plant's operational stability and anti-interference capability when the power grid frequency fluctuates drastically, avoiding the risk of frequent mode switching or operational instability caused by frequency mutations. While improving the efficiency of multi-dispatch collaborative control, it also enhances the security and robustness of multi-dispatch collaborative control.

[0096] In one embodiment, step S102, if the current grid state information meets the preset grid state conditions, determines the current operating mode of the power plant based on the current demand overlap between at least two current dispatch demand information. Specifically, this includes: if the grid frequency fluctuation value is less than or equal to a preset fluctuation threshold, comparing the current demand overlap with a preset overlap threshold; the preset overlap threshold includes a first overlap threshold and a second overlap threshold; the first overlap threshold is greater than the second overlap threshold; if the current demand overlap is greater than or equal to the first overlap threshold, the combined plant mode is determined as the current operating mode of the power plant; if the current demand overlap is less than or equal to the second overlap threshold, the branch plant mode is determined as the current operating mode of the power plant.

[0097] The combined plant mode refers to treating all operating units of a power plant as a unified whole for scheduling and management. For example, based on internal rules such as unit response speed and efficiency, the load of each unit is autonomously allocated, as long as the total output meets the target. The combined plant mode is suitable for scenarios where dual dispatching needs are consistent and the overall capacity of the power plant needs to be utilized centrally, such as load superposition allocation during cross-regional power complementarity.

[0098] The branch plant model refers to dividing multiple target generating units within a power plant into independent units, each corresponding to a different power dispatching system or load demand. For example, each target generating unit can be assigned a dispatching affiliation; some units may exclusively respond to dispatching instructions from the power dispatching system in location A, while others may exclusively respond to dispatching instructions from the power dispatching system in location B. The branch plant model is suitable for scenarios with significantly different dual dispatching requirements and where instruction conflicts must be avoided, such as when different regions have different requirements for power reliability and response speed.

[0099] Specifically, if the grid frequency fluctuation is less than or equal to a preset fluctuation threshold, it can be considered that the grid frequency fluctuation is within a stable range. The ACG system then performs demand overlap analysis on at least two current dispatch demand information sets to obtain the current demand overlap. The system then compares the current demand overlap with a preset overlap threshold. If the current demand overlap is greater than or equal to the first overlap threshold (e.g., current demand overlap ≥ 30%), the AGC system can prioritize determining the combined plant mode as the power plant's current operating mode. If the current demand overlap is less than or equal to the second overlap threshold (e.g., current demand overlap ≤ 10%), the AGC system can prioritize determining the branch plant mode as the power plant's current operating mode.

[0100] In this embodiment, when the grid frequency fluctuation is less than or equal to a preset fluctuation threshold, the current demand overlap is compared with a preset overlap threshold, and the power plant's operating mode is intelligently selected based on the overlap range: if the current demand overlap is greater than or equal to a higher first overlap threshold, a combined plant mode is adopted to improve operating efficiency and coordination; if the current demand overlap is less than or equal to a lower second overlap threshold, a separate plant mode is adopted to enhance dispatch flexibility and independence. This hierarchical decision-making mechanism effectively achieves precise matching between the power plant's operating mode and the multi-source dispatch demand, avoiding operational conflicts caused by forced merging when demand differences are large, and fully leveraging the advantages of intensive operation when demand is highly consistent. Thus, while ensuring grid frequency stability, it significantly improves the optimization and allocation capabilities of power dispatch resources and the overall operational reliability.

[0101] In one embodiment, step S105 above, based on the updated operating mode, performs power dispatch processing on the power plant to obtain the power dispatch result of the power plant, specifically including the following: If the updated operating mode represents a combined plant mode, then according to at least two updated dispatch demand information and the weights corresponding to each power dispatch system, the generating units of the power plant are jointly dispatched and allocated to obtain the combined plant dispatch allocation result of the generating units, and based on the combined plant dispatch allocation result, the generating units are controlled to perform power dispatch processing to obtain the power dispatch result of the power plant; If the updated operating mode represents a separate plant mode, then according to at least two updated dispatch demand information, the generating units of the power plant are independently dispatched and allocated to obtain the separate plant dispatch allocation result of the generating units, and based on the separate plant dispatch allocation result, the generating units are controlled to perform power dispatch processing to obtain the power dispatch result of the power plant.

[0102] Specifically, if the updated operating mode represents the combined plant mode, then the power plant's generating units are jointly dispatched and allocated based on at least two updated dispatch demand information and the corresponding weights of each power dispatch system. For example, the first dispatch demand information accounts for 60% of the unit's operation, and the second dispatch demand information accounts for 40% of the unit's operation, so as to convert at least two updated dispatch demand information into a unified dispatch target, thereby obtaining the combined plant dispatch allocation result of the generating units. Based on the combined plant dispatch allocation result, the AGC system controls the generating units to perform power dispatch processing to obtain the power dispatch result of the power plant.

[0103] If the updated operating mode represents the branch plant mode, then based on at least two updated scheduling demand information, the power plant's units are independently scheduled and allocated. For example, a dedicated unit is allocated for the first scheduling demand information and a dedicated unit is allocated for the second scheduling demand information to obtain the branch plant scheduling allocation result of the unit, so as to avoid mutual interference between independent scheduling demand information during transmission and execution. Based on the branch plant scheduling allocation result, the AGC system controls the unit to perform power scheduling processing to obtain the power plant's power scheduling result.

[0104] In this embodiment, by selecting the appropriate scheduling and allocation strategy based on the updated operating mode, if the updated operating mode is a combined plant mode, the power plant units are jointly scheduled and allocated based on the updated scheduling requirements and weights of each power dispatching system to achieve resource synergy optimization. If the updated operating mode is a separate plant mode, the units are independently scheduled and allocated according to their respective scheduling requirements to ensure operational flexibility and autonomy. This method enables differentiated and precise scheduling of power plants under different operating modes, improving overall scheduling efficiency in multi-scheduling collaborative scenarios and ensuring agility and relevance of scheduling responses in independent scheduling scenarios.

[0105] In one embodiment, such as Figure 3As shown, another method for coordinated control using multiple scheduling commands is provided. Taking the application of this method to an automatic generation control system as an example, the method includes the following steps:

[0106] Step S301: Receive current dispatch instructions issued by at least two power dispatch systems for the power plant, and obtain the current grid status information of the power plant; the current dispatch instructions carry corresponding current dispatch demand information; the current grid status information includes the current grid frequency.

[0107] Step S302: Based on the frequency difference between the current grid frequency and the power plant's historical grid frequency, obtain the power plant's grid frequency fluctuation value.

[0108] Step S303: If the power grid frequency fluctuation value is less than or equal to a preset fluctuation threshold, then the current demand overlap between at least two current scheduling demand information is compared with a preset overlap threshold; the preset overlap threshold includes a first overlap threshold and a second overlap threshold; the first overlap threshold is greater than the second overlap threshold.

[0109] Step S304: If the current demand overlap is greater than or equal to the first overlap threshold, then the plant merging mode is determined as the current operating mode of the power plant.

[0110] Step S305: If the current demand overlap is less than or equal to the second overlap threshold, then the branch plant mode is determined as the current operating mode of the power plant.

[0111] Step S306: Upon receiving updated dispatch instructions issued by at least two power dispatch systems for the power plant, perform demand overlap analysis on the updated dispatch demand information carried in the at least two updated dispatch instructions to obtain the updated demand overlap.

[0112] Step S307: Obtain the overlap change information of the updated demand overlap based on the overlap difference between the current demand overlap and the updated demand overlap.

[0113] Step S308: If the detected overlap change information meets the preset overlap change conditions, then based on the current operating mode, a mode switching message is generated and sent to at least two power dispatching systems respectively.

[0114] Step S309: The load, circuit breaker and load of the power plant are adjusted in sequence to obtain the adjusted power plant; the current operating mode is switched to obtain the updated operating mode of the adjusted power plant.

[0115] Step S310: If the updated operating mode represents the combined plant mode, then according to at least two updated scheduling demand information and the weights corresponding to each power dispatching system, the power plant units are jointly dispatched and allocated to obtain the combined plant scheduling allocation result of the units. Based on the combined plant scheduling allocation result, the units are controlled to perform power dispatching processing to obtain the power dispatching result of the power plant.

[0116] Step S311: If the updated operating mode represents the branch plant mode, then based on at least two updated scheduling demand information, the generating units of the power plant are independently scheduled and allocated to obtain the branch plant scheduling allocation result of the generating units. Based on the branch plant scheduling allocation result, the generating units are controlled to perform power scheduling processing to obtain the power scheduling result of the power plant.

[0117] The aforementioned multi-dispatch command collaborative control method can achieve the following beneficial effects: when the current grid state information of the power plant meets the grid state conditions, the current operating mode of the power plant is intelligently determined based on the demand overlap between dispatch commands issued by multiple power dispatching systems; when the dispatch commands are updated, the updated demand overlap between the updated dispatch commands is dynamically analyzed and compared with the current overlap, thereby adaptively updating and optimizing the operating mode of the power plant. This method effectively solves the problems of difficulty in coordinating multi-source dispatch commands and command delay or conflict during mode switching, realizing rapid and accurate switching and dynamic coordination of the operating mode of the power plant in the multi-dispatch collaborative control scenario, thereby improving the switching efficiency of the power plant's operating mode, and also helping to improve the real-time performance, flexibility, and operational safety and stability of power dispatching.

[0118] To more clearly illustrate the multi-scheduling command cooperative control method provided in this disclosure, a specific embodiment is used to describe the above-mentioned multi-scheduling command cooperative control method in detail below. Another multi-scheduling command cooperative control method is provided, which can be applied to an automatic generation control system, and specifically includes the following:

[0119] 1. Real-time monitoring of key parameters for status assessment

[0120] Collect core parameters using a SCADA system:

[0121] (1) Physical status: total number of incoming and outgoing circuits, circuit breaker closed status, switch closed status;

[0122] (2) Scheduling demand: The degree of overlap between multiple scheduling demand information. Based on the current degree of overlap, the current operating mode of the power plant is determined. For example, if the current degree of overlap is ≥30%, the combined plant mode is adopted, and if the current degree of overlap is ≤10%, the separate plant mode is adopted.

[0123] (3) Power grid status: Calculate the frequency difference between the current power grid frequency and the historical power grid frequency to obtain the power grid frequency fluctuation value. If the power grid frequency fluctuation value is greater than the preset fluctuation threshold (e.g., 0.2Hz), then lock the power plant's current operating mode to avoid frequent switching of operating modes.

[0124] 2. Smooth transition control for state switching

[0125] When the overlap change information meets the preset overlap change conditions (e.g., the required overlap decreases from 40% to 5%), the following three stages are executed:

[0126] (1) Pre-switching phase: Based on the current operating mode, generate a mode switching message; send the mode switching message to each power dispatching system 10 seconds in advance, that is, give advance notice to each power dispatching system that the power plant's operating mode is about to be switched, so that each power dispatching system will stop issuing dispatching instructions in the future time period and simultaneously freeze unnecessary load adjustment instructions.

[0127] (2) Switching execution phase: First, adjust the load of the power plant unit to a safe range (e.g., reduce it to 90% of the target value), then open / close the circuit breaker (millisecond-level operation), and then restore the load to the target value. That is, operate in the order of "load → circuit breaker → load" in sequence, and also avoid the frequency fluctuation of the power plant exceeding the target frequency fluctuation threshold (e.g., 0.1Hz) during the switching process; finally, the updated operation mode of the power plant after adjustment is obtained.

[0128] (3) Post-switch adaptation: Automatically update the dispatch instruction receiving logic. For example, when the updated operating mode is the combined plant mode, it receives dispatch instructions jointly controlled by multiple power dispatch systems. When the updated operating mode is the branch plant mode, it receives dispatch instructions independently controlled by each power dispatch system.

[0129] 3. Dynamic adaptation and execution of dual scheduling instructions

[0130] The response logic for scheduling instructions is automatically adjusted based on the updated operating mode:

[0131] (1) The updated operating mode is the combined plant mode: the first dispatching instruction issued by the first power dispatching system and the second dispatching instruction issued by the second power dispatching system are converted into a unified dispatching target according to the "weight allocation" (for example, the first dispatching demand information corresponding to the first dispatching instruction accounts for 60% of the unit operation, and the second dispatching demand information corresponding to the second dispatching instruction accounts for 40% of the unit operation).

[0132] (2) The updated operating mode is the branch plant mode: an independent "instruction channel" is allocated for the first and second scheduling instructions, that is, a dedicated unit is allocated to execute the first and second scheduling instructions independently, so as to avoid mutual interference between scheduling instructions during transmission and execution.

[0133] In this embodiment, the following beneficial effects can be achieved: when the current grid state information of the power plant meets the grid state conditions, the current operating mode of the power plant is intelligently determined based on the demand overlap between dispatch instructions issued by multiple power dispatching systems; when the dispatch instructions are updated, the updated demand overlap between the updated dispatch instructions is dynamically analyzed and compared with the current overlap, thereby adaptively updating and optimizing the operating mode of the power plant. This method effectively solves the problem of instruction delay or conflict that easily occurs when the AGC system switches modes, and realizes fast and accurate switching and dynamic coordination of the operating mode of the power plant in the multi-dispatch collaborative control scenario, thereby improving the switching efficiency of the power plant's operating mode, and also helps to improve the real-time performance, flexibility, and operational safety and stability of power dispatching.
