Description

Technical Field

[0001] This application relates to the field of power grid technology, and in particular to a load processing method, apparatus, power equipment, storage medium and computer program product under multi-dispatch joint control. Background Technology

[0002] Automatic Generation Control (AGC) was initially used to achieve dynamic matching of load and capacity within a single area. It features fast response and simple control logic. As a result, AGC systems have been widely used in power systems under the jurisdiction of a single dispatch center at the provincial or regional level, becoming a key technical support for ensuring the stable operation of the power grid.

[0003] With the increasing trend of cross-regional interconnection of power systems, power grid dispatching technology is gradually evolving from independent dispatching in a single region to collaborative dispatching across multiple regions. However, traditional single-region dispatching methods tend to overlook the load demands of other dispatching centers and cannot resolve cross-regional dispatching command conflicts. When command conflicts occur, dispatchers need to manually communicate and negotiate to adjust command parameters before issuing them to the AGC system for execution, resulting in low efficiency of cross-regional joint dispatching. Summary of the Invention

[0004] Therefore, it is necessary to provide a load processing method, apparatus, power equipment, computer-readable storage medium, and computer program product under multi-scheduling joint control to address the above-mentioned technical problems.

[0005] Firstly, this application provides a load processing method under multi-scheduling joint control. The method includes:

[0006] Obtain the first dispatch instruction issued by the first power dispatch system, obtain the second dispatch instruction issued by the second power dispatch system, and obtain the current operating status of the power plant;

[0007] Based on the operating mode selected in the current operating state, multi-target scheduling allocation processing is performed on the first scheduling requirement information in the first scheduling instruction and the second scheduling requirement information in the second scheduling instruction to obtain the scheduling allocation result for the power plant.

[0008] Based on the scheduling and allocation results, the power plant's generating units are controlled to perform load allocation processing to obtain the allocated load information of the generating units;

[0009] The load allocation execution result of the power plant is obtained based on the load deviation between the allocated load information and the target load information in the scheduling allocation result.

[0010] In one embodiment, based on the operating mode selected in the current operating state, multi-target scheduling allocation processing is performed on the first scheduling requirement information in the first scheduling instruction and the second scheduling requirement information in the second scheduling instruction to obtain a scheduling allocation result for the power plant, including:

[0019] If the load deviation is greater than the preset load deviation threshold, then based on the scheduling and allocation results, the load of the unit is fine-tuned to obtain updated post-allocation load information, until the load deviation between the post-allocation load information and the target load information is less than or equal to the preset load deviation threshold.

[0020] In one embodiment, the method further includes:

[0021] In response to a received cross-dispatch load transfer instruction between the first power dispatching system and the second power dispatching system, the initial transfer setting information corresponding to the cross-dispatch load transfer instruction is obtained;

[0034] The result acquisition module is used to obtain the load allocation execution result of the power plant based on the load deviation between the allocated load information and the target load information in the scheduling allocation result.

[0035] Thirdly, this application also provides a power device. The power device includes a memory and a processor, the memory storing a computer program, and the processor executing the computer program to perform the following steps:

[0039] The load allocation execution result of the power plant is obtained based on the load deviation between the allocated load information and the target load information in the scheduling allocation result.

[0040] 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:

[0044] The load allocation execution result of the power plant is obtained based on the load deviation between the allocated load information and the target load information in the scheduling allocation result.

[0045] 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:

This method synchronously acquires dispatch instructions from dual power dispatch systems and the current operating status of power plants. It then performs multi-objective dispatch allocation processing on the dual dispatch demand information based on the selected operating mode. Following the dispatch allocation results, it controls the power plant's generating units to perform load allocation and obtains the load allocation execution result through load deviation verification. This not only achieves coordinated adaptation and differentiated response of dual dispatch instructions, effectively balancing the load demands of different dispatch systems and improving the allocation efficiency of cross-regional power resources, but also ensures the accuracy and rationality of unit load allocation through full-process control of operating mode adaptation, multi-objective optimized allocation, and load deviation verification. It reduces grid frequency fluctuations caused by dispatch instruction conflicts, enhances the stability and reliability of cross-regional power dispatch, and avoids the response lag and errors of traditional manual coordination or single dispatch priority modes, thus improving the operational efficiency of multi-dispatch joint control.

[0057] 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.

[0058] 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.

[0059] In one embodiment, such as Figure 1 As shown, a load processing method under multi-scheduling joint control 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 system 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:

[0060] Step S101: Obtain the first dispatch instruction issued by the first power dispatch system, obtain the second dispatch instruction issued by the second power dispatch system, and obtain the current operating status of the power plant.

[0061] In this context, both the first and second power dispatching systems refer to independent control entities with power dispatching authority, typically dispatching agencies in different regions, at different levels, or with different jurisdictions. For example, the first power dispatching system might be the power dispatching system for location A, and the second power dispatching system might be the power dispatching system for location B.

[0062] Among them, the first power dispatch instruction refers to the power dispatch instruction of the first power dispatch system for the AGC system.

[0063] Among them, the second power dispatch instruction refers to the power dispatch instruction of the second power dispatch system for the AGC system.

[0064] Specifically, the power dispatching system in location A (i.e., the first power dispatching system) and the power dispatching system in location B (i.e., the second power dispatching system) can simultaneously issue dispatching instructions to the AGC system. In turn, the AGC system can synchronously receive the first dispatching instruction issued by the first power dispatching system and the second dispatching instruction issued by the second power dispatching system. At the same time, the AGC system can also read the current operating status of the power plant.

[0065] The current operating status refers to the power plant's operating parameters under current conditions. The current operating status includes operating modes, unit operating data, and the maximum load capacity of individual units, among other operating parameters.

[0066] Furthermore, the AGC system parses the first and second scheduling instructions to extract scheduling demand information (such as load setpoint, capacity setpoint, and scheduling priority) from the first and second scheduling instructions respectively. The AGC system then obtains the first and second scheduling demand information and combines the first and second scheduling demand information with the current operating status of the power plant to generate a basic data pool.

[0067] Step S102: Based on the operating mode selected in the current operating state, perform multi-target scheduling allocation processing on the first scheduling demand information in the first scheduling instruction and the second scheduling demand information in the second scheduling instruction to obtain the scheduling allocation result for the power plant.

[0068] The dispatch allocation result refers to the description of the units (target units) in the power plant that respond to dispatch instructions and the load allocation information of these units.

[0069] Specifically, the AGC system uses corresponding algorithms to perform multi-objective scheduling and allocation processing on the basic data pool according to the operating mode currently selected by the power plant. This can be done by first identifying multiple units in the power plant that are used to respond to scheduling instructions and setting them as target units, and then determining the load allocation results for each target unit. In other words, the AGC system obtains the scheduling and allocation results.

[0070] Step S103: Based on the scheduling and allocation results, control the power plant's generating units to perform load allocation processing and obtain the allocated load information of the generating units.

[0071] Among them, the post-allocation load information refers to the actual load of the target unit after it has been operated according to the scheduling allocation results.

[0072] Specifically, the AGC system controls the target units of the power plant to operate and output power according to the scheduling allocation results, and monitors the actual load of the target units in real time after the target units execute the scheduling allocation results, that is, the load information of the target units after allocation.

[0073] Step S104: Based on the load deviation between the allocated load information and the target load information in the scheduling allocation result, the load allocation execution result of the power plant is obtained.

[0074] Specifically, the AGC system calculates the load deviation between the allocated load information and the target load information in the scheduling allocation result to determine whether the scheduling allocation result is accurate and effective. Based on the load deviation, it determines whether to adjust the load of the target unit to allocate the load of the target unit more accurately. Finally, the ACG feeds back the load allocation execution result to the first scheduling system and the second power scheduling system respectively.

[0075] In the aforementioned load processing method under multi-dispatch joint control, by synchronously acquiring dispatch instructions issued by the dual power dispatch systems and the current operating status of the power plant, and combining the selected operating mode to perform multi-objective dispatch allocation processing on the dual dispatch demand information, and then controlling the power plant units to perform load allocation based on the dispatch allocation results, and obtaining the load allocation execution result through load deviation verification, this method not only achieves coordinated adaptation and differentiated response of dual dispatch instructions, effectively taking into account the load demand of different dispatch systems and improving the allocation efficiency of cross-regional power resources, but also ensures the accuracy and rationality of unit load allocation through full-process control of operating mode adaptation, multi-objective optimized allocation and load deviation verification, reduces grid frequency fluctuations caused by dispatch instruction conflicts, enhances the stability and reliability of cross-regional power dispatch, and avoids the response lag and error of traditional manual coordination or single dispatch priority mode, thus improving the operating efficiency of multi-dispatch joint control.

[0076] In one embodiment, step S102 above, based on the operating mode selected in the current operating state, performs multi-objective scheduling allocation processing on the first scheduling demand information in the first scheduling instruction and the second scheduling demand information in the second scheduling instruction to obtain the scheduling allocation result for the power plant. Specifically, this includes the following: when the operating mode is the combined plant mode, performing demand fusion processing on the first scheduling demand information and the second scheduling demand information to obtain the total scheduling demand information of the first power dispatching system and the second power dispatching system; and performing scheduling allocation processing on the power plant's generating units based on the preset multi-objective information, the current operating parameters in the current operating state, and the total scheduling demand information to obtain the scheduling allocation result of the generating units.

[0077] 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.

[0078] Specifically, when the operating mode is detected as a combined plant mode, the AGC system first integrates the first dispatch demand information (such as load setpoint, capacity setpoint, and dispatch priority) of the first power dispatch system with the second dispatch demand information of the second power dispatch system. It does not distinguish between the independent demands of the two power dispatch systems, but only calculates the total load demand to form a unified total dispatch demand information. For example, assuming that the power dispatch system in area A requires 1000MW of load and the power dispatch system in area B requires 800MW of load, then the integrated total dispatch demand information would be 1800MW of load (which must simultaneously meet the capacity constraints of dual dispatch).

[0079] Furthermore, the AGC system integrates pre-set multi-objective information (such as regional power demand matching degree, unit response speed, grid frequency stability and unit operating efficiency), current operating parameters (such as the number of operating units, the upper / lower load limit of each unit, etc.) and overall dispatch demand information to assign specific output tasks to all units of the power plant. In the allocation, all objectives are taken into account. For example, the units with faster response are given priority to take on the load, while ensuring that the principle of "total load ≤ total power plant capacity + 5% fault tolerance rate" is met. Finally, the dispatch allocation result (i.e. how much load each unit should take on) is obtained.

[0080] In this embodiment, under the combined plant mode, the total dispatch demand information is obtained by fusing the dispatch demand information of the first and second power dispatch systems. Combined with preset multi-objective information and the current operating parameters of the power plant, the unit dispatch allocation is carried out. This not only achieves efficient integration and unified response of the dual dispatch demands, ensuring the synchronous satisfaction of the load demands of the dual power dispatch systems, but also, through multi-objective optimization and precise adaptation to the actual operating status of the power plant, makes the power plant unit output allocation more in line with core objectives such as grid frequency stability, unit response speed, and operating efficiency. This ensures the accurate implementation of the total dispatch demand and maximizes the overall operating efficiency of the power plant units, effectively improving the synergy of cross-regional power dispatch, the rationality of resource allocation, and the stability and economy of power system operation.

[0081] In one embodiment, the scheduling allocation result includes a first scheduling allocation result and a second scheduling allocation result. Step S102 above, based on the operating mode selected in the current operating state, performs multi-objective scheduling allocation processing on the first scheduling demand information in the first scheduling instruction and the second scheduling demand information in the second scheduling instruction to obtain a scheduling allocation result for the power plant. Specifically, this includes the following: when the operating mode is branch plant mode, scheduling allocation processing is performed on the power plant's generating units based on the first scheduling demand information and preset multi-objective information to obtain a first scheduling allocation result for the first generating unit in the power plant; scheduling allocation processing is performed on the power plant's generating units based on the first scheduling demand information and multi-objective information to obtain a second scheduling allocation result for the second generating unit in the power plant.

[0082] The branch plant mode refers to dividing multiple target generating units of 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 system, such as some units exclusively responding to power dispatching system C, while others exclusively respond to power dispatching system D. The branch plant mode is suitable for scenarios with significant differences in dual dispatching needs and where command conflicts must be avoided, such as when different regions have different requirements for power reliability and response speed.

[0083] Specifically, when the operating mode is detected to be branch plant mode, the AGC system first groups the power plant's generating units according to the first and second scheduling requirements. For example, it assigns two generating units to the first generating unit, which is responsible for responding exclusively to the first scheduling command of the first power dispatch system, and assigns three generating units to the second generating unit, which is responsible for responding exclusively to the second scheduling command of the second power dispatch system. Thus, the AGC system obtains the first and second generating units. Then the AGC system independently allocates load tasks to the first and second units: (1) For the first unit: based only on the first dispatch demand information of the first power dispatch system (such as the first load setting value and the first capacity setting value), combined with the preset multi-objective information (such as grid frequency stability, unit response speed, etc.), the specific output allocation of the first unit is calculated (for example, unit E in the first unit bears 500MW load and unit F bears 400MW load), and finally the first dispatch allocation result is obtained; (2) For the second unit: based only on the second dispatch demand information of the second power dispatch system (such as the second load setting value and the second capacity setting value), combined with the above multi-objective information, the specific output allocation of the second unit is calculated, and the second dispatch allocation result is obtained.

[0084] In this embodiment, under the branch plant mode, the power plant units are divided into a first unit and a second unit. Independent scheduling allocations are then performed based on the first scheduling demand information, the second scheduling demand information, and multi-objective information, resulting in corresponding first and second scheduling allocation results. This not only achieves a customized response to the scheduling demand information of the dual power dispatch system and clarifies the scheduling boundaries of different units, effectively avoiding conflicts between dual dispatch commands on the same unit and ensuring the accurate implementation of each scheduling demand, but also, through independent optimization allocation for different units, ensures that the output of each unit aligns with multi-objective information (such as grid frequency stability and unit response speed) and corresponding scheduling demand information. This improves the efficiency and accuracy of the execution of each command in the dual power dispatch system, ensures the stability and relevance of unit operation, and further enhances the adaptability and reliability of cross-regional power dispatch in scenarios with differentiated demands.

[0085] In one embodiment, step S104 above, which obtains the load allocation execution result of the power plant based on the load deviation between the allocated load information and the target load information in the scheduling allocation result, specifically includes the following: if the load deviation between the allocated load information and the target load information in the scheduling allocation result is less than or equal to a preset load deviation threshold, then the load allocation execution result of the power plant is confirmed as successful, and the load allocation execution result is returned to the first power dispatching system and the second power dispatching system respectively; if the load deviation is greater than the preset load deviation threshold, then based on the scheduling allocation result, the load of the unit is fine-tuned to obtain updated allocated load information, until the load deviation between the allocated load information and the target load information is less than or equal to the preset load deviation threshold.

[0086] Specifically, the AGC system can pre-set a deviation threshold for the load, i.e., a preset load deviation threshold. After the target units operate according to the dispatch allocation results, the AGC system monitors the actual load of each target unit in real time, i.e., obtains the allocated load information, and calculates the load deviation between the allocated load information and the target load information in the dispatch allocation results. If the load deviation is less than or equal to the preset load deviation threshold (e.g., ≤1%), it indicates that the actual output of the target units meets the target, and the load allocation execution result of the power plant is confirmed as successful. The load allocation execution result is then synchronously sent to the first power dispatch system and the second power dispatch system. If the load deviation is greater than the preset load deviation threshold (e.g., >1%), it indicates that the actual output of the target unit is not up to standard. In this case, the load fine-tuning of the target unit (including the first unit and / or the second unit) is initiated (e.g., increasing or decreasing the load of a single target unit) to avoid large-scale adjustments causing excessive fluctuations in grid frequency and thus affecting the stability of grid operation. The updated load information after allocation continues to be collected in real time, and the load deviation between the new allocated load information and the target load information is recalculated. It is then determined whether the new load deviation is less than or equal to the preset load deviation threshold. This process continues until the load deviation is less than or equal to the preset load deviation threshold, ensuring that the final load allocation execution result meets the standard.

[0087] In this embodiment, by setting a preset load deviation threshold, the load deviation between the allocated load information of the target unit and the target load information is determined and dynamically processed. When the load deviation is less than or equal to the preset load deviation threshold, the load allocation execution result is confirmed as successful, and the load allocation execution result is synchronously fed back to the dual power dispatching system. When the load deviation is greater than the preset load deviation threshold, the load of the target unit is automatically fine-tuned and the load deviation is repeatedly calculated and judged to ensure that the execution accuracy of the dispatching allocation result is guaranteed. The automatic correction of load deviation also reduces the cost of manual intervention and improves the execution response efficiency under multi-dispatch joint control. At the same time, the execution status is fed back to the dual power dispatching system in real time, ensuring that the dual power dispatching system has accurate control over the load allocation process, and further enhancing the reliability, stability and transparency of cross-regional dual dispatching collaboration.

[0088] In one embodiment, such as Figure 2 As shown, the load processing method under the above-mentioned multi-scheduling joint control also includes:

[0089] Step S201: In response to the received cross-dispatch load transfer instruction between the first power dispatching system and the second power dispatching system, obtain the initial transfer setting information corresponding to the cross-dispatch load transfer instruction.

[0090] Among them, cross-dispatch load transfer instructions refer to adjustment instructions issued between two independent power dispatching systems regarding load allocation. Cross-dispatch load transfer instructions are used to transfer a portion of the power load originally under the jurisdiction of one dispatching system to the jurisdiction of another dispatching system, thereby adjusting the load allocation ratio among multiple power dispatching systems.

[0091] The initial transfer setting information refers to the original parameters set for cross-schedule load transfer.

[0092] Specifically, when the AGC system receives a cross-dispatch load transfer instruction between the first and second power dispatching systems (for example, transferring part of the load of the first power dispatching system in location A to the second power dispatching system in location B), it first extracts the initial transfer setting information (such as the amount of load to be transferred, the target load value of each power dispatching system after the transfer, capacity constraints, etc.) from the cross-dispatch load transfer instruction.

[0093] Step S202: Perform fault tolerance analysis on the initial transfer setting information to obtain the fault tolerance analysis results of the initial transfer setting information.

[0094] Specifically, the AGC system performs fault tolerance analysis on the initial transfer settings to determine whether there are any error risks (such as whether the transfer amount exceeds the power plant's total capacity redundancy or whether it may cause grid frequency fluctuations), and generates fault tolerance analysis results.

[0095] The results of the tolerance analysis can be either qualified or unqualified, and can also be specific deviation data.

[0096] Step S203: Based on the fault tolerance analysis results, update the initial transfer setting information to obtain candidate transfer setting information for the first power dispatching system and the second power dispatching system.

[0097] Specifically, the AGC system determines whether the cross-schedule load transfer conditions are met based on the fault tolerance analysis results. If not, an alarm is triggered and the initial transfer settings are adjusted and optimized (such as correcting the excessive transfer amount and adjusting the target load allocation ratio), generating new transfer settings and setting them as candidate transfer settings (i.e., the optimized transfer scheme).

[0098] Step S204: Verify the candidate transfer setting information to obtain the verification result of the candidate transfer setting information.

[0099] Specifically, the candidate transfer setting information is fully verified again (for example, whether it meets the capacity limit, whether it exceeds the frequency stability threshold, whether it exceeds the load fluctuation threshold, and other cross-scheduling load transfer conditions) to obtain the verification results of the candidate transfer setting information.

[0100] Step S205: If the verification result indicates that the verification is successful, the candidate transfer setting information is confirmed as the target transfer setting information for the first power dispatching system and the second power dispatching system.

[0101] Specifically, if the verification result of the candidate transfer setting information indicates that the verification passes, then the AGC system will determine the candidate transfer setting information as the final target transfer setting information. If the verification result of the candidate transfer setting information indicates that the verification fails, then the AGC system can continue to adjust and optimize the candidate transfer setting information until the verification passes.

[0102] Step S206: Based on the target transfer setting information, perform load transfer processing between the first power dispatching system and the second power dispatching system to obtain the target load transfer execution results of the first power dispatching system and the second power dispatching system.

[0103] Specifically, the AGC system generates load transfer instructions (including unit start-up and shutdown sequence, load adjustment rate, etc.) according to the target information, and then uses the load transfer instructions to control the two power dispatching systems to perform load transfer processing, and finally obtains the load transfer execution result (whether the transfer was successful, the load compliance status of the dual dispatching after the transfer, etc.).

[0104] Furthermore, during the load transfer process, it is necessary to continuously monitor the load of the first power dispatching system and the second power dispatching system to obtain the transfer information. Referring to step S104 above, the transfer load deviation between the transfer load information and the set load information in the target transfer setting information is calculated. If the transfer load deviation is less than or equal to the preset transfer load deviation threshold (e.g., 1%), the load transfer execution result of the power plant is confirmed as successful, and the load transfer execution result is returned to the first power dispatching system and the second power dispatching system respectively. If the transfer load deviation is greater than the transfer load deviation threshold, the load of the first power dispatching system or the second power dispatching system is fine-tuned based on the target transfer setting information until the transfer load deviation between the transfer load information and the set load information is less than or equal to the transfer load deviation threshold, so as to avoid load fluctuations exceeding the load fluctuation threshold (e.g., 500kV / 18kV) and ensure that the grid frequency is stable within the target frequency range (e.g., 50Hz±0.1Hz).

[0105] In this embodiment, upon receiving a cross-dispatch load transfer instruction, the system acquires initial transfer settings, performs fault tolerance analysis, updates and generates candidate transfer settings, and verifies them. Finally, it executes cross-domain load transfer based on the verified target transfer settings. Through three levels of verification, the system ensures the accuracy of the target transfer settings and that they meet the requirements of the dual dispatch system and grid security constraints (such as frequency stability thresholds). This avoids grid fluctuations caused by instruction conflicts or improper parameters, achieving smooth and error-free load transfer between the first and second power dispatch systems. It also improves the coordination and reliability of cross-regional power dispatch and provides strong support for the efficient linkage of the dual dispatch system.

[0106] In one embodiment, step S202 above, which involves performing fault tolerance analysis on the transfer setting information to obtain the fault tolerance analysis result of the transfer setting information, specifically includes the following: obtaining load transfer execution information between the first power dispatching system and the second power dispatching system; performing fault tolerance analysis processing on the load transfer execution information and the set load transfer information in the transfer setting information to obtain the fault tolerance analysis result.

[0107] Load transfer execution information refers to the values ​​(i.e., execution values) monitored in real time by different power dispatching systems during load transfer. For example, load transfer execution information includes dynamic data such as the actual amount of load transferred, the current transfer progress, real-time load changes, and grid frequency fluctuations.

[0108] Specifically, during the load transfer between the first and second power dispatching systems, the AGC system collects load transfer execution information in real time, including the actual amount of load transferred, the current transfer progress, real-time load changes in the dual power dispatching systems, and dynamic data such as grid frequency fluctuations. The AGC system compares the load transfer execution information with the set load transfer information in the transfer setting information. This can involve calculating the load transfer deviation between the two sets of information. For example, if 480MW was actually transferred but the setting was to transfer 500MW, the deviation would be 20MW. Another example is if the frequency fluctuation exceeds the target frequency range of 50Hz ± 0.1Hz. Ultimately, this results in a fault tolerance analysis.

[0109] Among them, the fault tolerance analysis results refer to whether the load transfer deviation and frequency fluctuation are within the allowable range (such as whether they are ≤2% fault tolerance rate) and whether there are risks that affect the safety of the transfer.

[0110] In this embodiment, by acquiring load transfer execution information between the first and second power dispatching systems in real time and performing fault tolerance analysis on it with the set load transfer information in the transfer setting information to obtain the analysis results, not only is dynamic monitoring and deviation tracing of the cross-dispatch load transfer process realized, but also the difference between the actual transfer situation and the preset plan can be captured in a timely manner. This effectively avoids risks such as power grid frequency fluctuations and load distribution imbalances caused by the accumulation of deviations during the load transfer process. Furthermore, it provides accurate data support for whether the transfer strategy needs to be adjusted in the future, ensuring that the load transfer always conforms to the needs of the dual dispatching system and the power grid security constraints. This improves the controllability, accuracy and security of cross-dispatch load transfer and further enhances the stability and reliability of the dual dispatching collaborative operation.

[0111] In one embodiment, such as Figure 3 As shown, another load processing method under multi-scheduling joint control is provided. Taking the application of this method to an AGC system as an example, the method includes the following steps:

[0112] Step S301: Obtain the first dispatch instruction issued by the first power dispatch system, obtain the second dispatch instruction issued by the second power dispatch system, and obtain the current operating status of the power plant.

[0113] Step S302: When the operating mode is the combined plant mode, the first scheduling demand information and the second scheduling demand information are fused to obtain the total scheduling demand information of the first power dispatching system and the second power dispatching system; based on the preset multi-objective information, the current operating parameters in the current operating state and the total scheduling demand information, the power plant units are scheduled and allocated to obtain the scheduling and allocation results of the units.

[0114] Step S303: When the operating mode is branch plant mode, the power plant's generating units are scheduled and allocated according to the first scheduling demand information and the preset multi-objective information to obtain a first scheduling allocation result for the first generating unit in the power plant; the power plant's generating units are scheduled and allocated according to the first scheduling demand information and the multi-objective information to obtain a second scheduling allocation result for the second generating unit in the power plant; the scheduling allocation result includes the first scheduling allocation result and the second scheduling allocation result.

[0115] Step S304: Based on the scheduling and allocation results, control the power plant's generating units to perform load allocation processing and obtain the allocated load information of the generating units.

[0116] Step S305: Based on the load deviation between the allocated load information and the target load information in the scheduling allocation result, the load allocation execution result of the power plant is obtained.

[0117] Step S306: In response to the received cross-dispatch load transfer instruction between the first power dispatching system and the second power dispatching system, obtain the initial transfer setting information corresponding to the cross-dispatch load transfer instruction.

[0118] Step S307: Perform fault tolerance analysis on the initial transfer setting information to obtain the fault tolerance analysis results of the initial transfer setting information.

[0119] Step S308: Based on the fault tolerance analysis results, update the initial transfer setting information to obtain candidate transfer setting information for the first power dispatching system and the second power dispatching system.

[0120] Step S309: Verify the candidate transfer setting information to obtain the verification result of the candidate transfer setting information.

[0121] Step S310: If the verification result indicates that the verification is successful, the candidate transfer setting information is confirmed as the target transfer setting information for the first power dispatching system and the second power dispatching system.

[0122] Step S311: Based on the target transfer setting information, perform load transfer processing between the first power dispatching system and the second power dispatching system to obtain the target load transfer execution results of the first power dispatching system and the second power dispatching system.

[0123] The load processing method under the above-mentioned multi-dispatch joint control can achieve the following beneficial effects: By synchronously acquiring the dispatch instructions issued by the dual power dispatch systems and the current operating status of the power plant, and combining the selected operating mode to perform multi-objective dispatch allocation processing on the dual dispatch demand information, and then controlling the power plant units to perform load allocation based on the dispatch allocation results, and obtaining the load allocation execution results through load deviation verification, it not only realizes the coordinated adaptation and differentiated response of dual dispatch instructions, effectively takes into account the load demand of different dispatch systems, and improves the allocation efficiency of cross-regional power resources, but also ensures the accuracy and rationality of unit load allocation through the whole-process control of operating mode adaptation, multi-objective optimized allocation and load deviation verification, reduces the grid frequency fluctuations caused by dispatch instruction conflicts, enhances the stability and reliability of cross-regional power dispatch, and avoids the response lag and error of traditional manual coordination or single dispatch priority mode, thus improving the operating efficiency of multi-dispatch joint control.

[0124] To more clearly illustrate the load processing method under multi-scheduling joint control provided in the embodiments of this disclosure, the following specific embodiment is used to describe the load processing method under multi-scheduling joint control. Another load processing method under multi-scheduling joint control is provided, which can be applied to an AGC system, and specifically includes the following:

[0125] 1. Real-time acquisition and parameter extraction of dual scheduling commands

[0126] The AGC system synchronously receives the first and second dispatch instructions from the first and second power dispatch systems, extracts core parameters (load setpoint, capacity setpoint, dispatch priority), and generates a basic data pool by combining the current operating status of the power plant (such as combined plant mode / branch plant mode, number of operating units, single unit load limit, etc.).

[0127] 2. Calculation of multi-objective optimization allocation model

[0128] Based on a pre-defined algorithm (integrating multi-objective information such as "regional power demand matching degree", "unit response speed", and "grid frequency stability"), the dual dispatch parameters are comprehensively calculated:

[0129] (1) Under the combined plant mode: the load demand in the dual dispatch demand information (i.e., the first dispatch demand information and the second dispatch demand information) is superimposed, and the unit output is allocated according to the principle of "total load ≤ total power plant capacity + 5% fault tolerance rate";

[0130] (2) In the branch plant mode: according to the dual dispatching demand information, the exclusive adjustment range of the unit is independently divided (such as designating 2 units to respond to the first power dispatching system and 2 units to respond to the second power dispatching system).

[0131] 3. Fault-tolerant control throughout the entire load transfer process

[0132] When a cross-dispatch load transfer is triggered (such as a load transfer from the first power dispatch system to the second power dispatch system):

[0133] (1) Start the load transfer mode and enter the target load and capacity settings for dual scheduling after the transfer;

[0134] (2) Ensure that there are no calculation errors by using a three-level verification process: “Calculation of the fault tolerance rate between the set value and the executed value (allowable deviation ≤ 2%) → Fault tolerance rate analysis (if the threshold is exceeded, an alarm is triggered and the calculation is recalculated) → Secondary verification of the set value after transfer”.

[0135] (3) Generate cross-dispatch load transfer instructions (including unit start-up and shutdown sequence and load adjustment rate) to avoid load fluctuations exceeding the 500kV / 18kV power grid frequency stability threshold (50Hz±0.1Hz).

[0136] 4. Instruction execution and status closed-loop feedback

[0137] After the unit executes the command, the AGC system monitors the deviation between the actual load and the target value (or set value) in real time. If the deviation is ≤1%, the execution is considered successful, and the execution result is fed back to the dual power dispatch system in a synchronous manner. If the deviation exceeds the limit, the system automatically starts to fine-tune the unit's load (such as increasing or decreasing the load of a single unit) until the target is met.

[0138] In this embodiment, by synchronously acquiring dispatch instructions issued by the dual power dispatch systems and the current operating status of the power plant, and combining the selected operating mode, the dual dispatch demand information is processed for multi-objective dispatch allocation. Then, based on the dispatch allocation results, the power plant's generating units are controlled to perform load allocation, and the load allocation execution results are obtained through load deviation verification. This not only achieves coordinated adaptation and differentiated response of dual dispatch instructions, effectively taking into account the load demands of different dispatch systems and improving the allocation efficiency of cross-regional power resources, but also ensures the accuracy and rationality of unit load allocation through full-process control of operating mode adaptation, multi-objective optimized allocation, and load deviation verification. It reduces grid frequency fluctuations caused by dispatch instruction conflicts, enhances the stability and reliability of cross-regional power dispatch, and avoids the response lag and errors of traditional manual coordination or single dispatch priority mode, thereby improving the operating efficiency of multi-dispatch joint control.
