Description

Technical Field

[0001] The present invention relates to the technical field of electric power, and in particular, to a load shedding execution method, a device, and an electronic device based on multi-level dispatching interaction. Background Art

[0002] Load shedding is an important accident handling measure in the safe operation of the power grid. It refers to the operation of cutting off some loads from the power grid by the dispatcher according to the actual operation situation of the power grid to restore the frequency and voltage of the power grid to the normal or allowable range when the power grid has a serious fault and causes power balance tension and equipment overload.

[0003] Currently, in the operation of the power grid, in order to ensure the safe and stable operation of the power grid, the power grid dispatching agency will set some boundary conditions for the system operation parameters, such as the lower limit of the system frequency, the lower limit of the regional voltage, and the upper limit of the load rates of equipment such as transformers and lines. Once the actual operation situation of the power grid exceeds these set limits, the dispatching agency will adjust the load in the power grid according to the comparison result between these actual values and the set values. When the actual operation situation of the power grid exceeds the set value, the dispatching agency can perform a load shedding operation, that is, the dispatching agency can cut off some power loads in the power grid to achieve the safe and stable operation of the power grid.

[0004] In the related art, the load shedding operation of the power grid is mainly directly completed by the provincial dispatching system or by the dispatcher sending a load shedding order to the local dispatching system to complete the load shedding operation. However, dispatching systems such as the provincial dispatching system and the local dispatching system cannot perform efficient automatic interaction, resulting in low load shedding efficiency.

[0005] In view of the above problems, no effective solution has been proposed yet. Summary of the Invention

[0006] The embodiments of the present invention provide a load shedding execution method, a device, and an electronic device based on multi-level dispatching interaction to at least solve the technical problem that the multi-level dispatching system in the related art cannot perform automatic interaction, resulting in low load shedding execution efficiency.

The memory is used to store one or more programs. When the one or more programs are executed by the one or more processors, the one or more processors are caused to implement any one of the above-mentioned pull-switch execution methods based on multi-level scheduling interaction.

[0023] In the present invention, a pull-switch request is received, and it is judged whether the provincial dispatching system can complete the target load capacity. In the case where the provincial dispatching system cannot complete the target load capacity, the provincial dispatching system is controlled to decompose the pull-switch capacity based on the target load capacity to obtain the pull-switch decomposition capacity of each local dispatching system. The provincial dispatching system is controlled to send an activation instruction to each local dispatching system, and in the case where the local dispatching system is successfully activated, the provincial dispatching system is controlled to send a control instruction to the local dispatching system, and the local dispatching system is controlled to execute the pull-switch based on the pull-switch decomposition capacity and the pull-switch plan information, thereby solving the technical problem in the related art that the multi-level scheduling system cannot perform automatic interaction, resulting in low pull-switch execution efficiency.

[0031] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily need to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units does not necessarily need to be limited to those clearly listed steps or units, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0033] It should be noted that the relevant information (including but not limited to user equipment information, user personal information, etc.) and data (including but not limited to data for analysis, stored data, displayed data, etc.) collected and involved in the present invention are all information and data authorized by the user or fully authorized by all parties. And the processing of relevant data such as collection, storage, use, processing, transmission, provision, disclosure and application all comply with the relevant laws, regulations and standards of the relevant regions, take necessary confidentiality measures, do not violate public order and good customs, and provide corresponding operation entrances for users to choose to authorize or refuse. For example, there is an interface between the present system and relevant users or institutions. Before obtaining relevant information, a request for acquisition needs to be sent to the aforementioned users or institutions through the interface, and after receiving the consent information fed back by the aforementioned users or institutions, the relevant information is obtained.

[0034] In the present invention, if the load capacity that needs to be disconnected in case of a severe fault is less than or equal to the total load that can be disconnected by the provincial dispatching system, the provincial dispatching system can directly disconnect the circuit. After starting the load batch disconnection module of the provincial dispatching system, it will automatically select and control the disconnection switches of the provincial dispatching system in the priority order in the disconnection sequence according to the target value. If the load capacity that needs to be disconnected in case of a severe fault is greater than the total load that can be disconnected by the provincial dispatching system, then the disconnection involves multiple levels of dispatching. In this case, the provincial-local integrated interaction function module is started, and the pre-plan selection and the setting of the target load disconnection of the local dispatching system are automatically completed. The pre-plan information and the local dispatching disconnection index are sent to each local dispatching system through the provincial-local measurement point forwarding interaction process. After receiving the instruction, the local dispatching system selects the specified pre-plan and sets the target disconnection amount, and automatically generates a control instruction sequence that mixes the whole line and the distribution network branch line in the sequence. Moreover, the whole line instruction is directly batch-remotely controlled and executed by the local dispatching system, and the distribution network branch line instruction is sent to the distribution dispatching system in the form of a control sequence list. The distribution dispatching system completes the automatic line selection according to the list and then performs the disconnection operation and reports it to the local dispatching system.

[0035] The present invention will be described in detail below in conjunction with each embodiment.

[0036] Embodiment 1

[0037] According to an embodiment of the present invention, an embodiment of a disconnection execution method based on multi-level dispatching interaction is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions. And although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0038] Figure 1 is a flowchart of an optional disconnection execution method based on multi-level dispatching interaction according to an embodiment of the present invention, as Figure 1 shown, the method includes the following steps:

[0039] Step S101, receive a disconnection request, and determine whether the provincial dispatching system can complete the target load capacity carried by the disconnection request, where the provincial dispatching system is used to remotely control the line switches whose voltages belong to the first preset voltage range.

[0040] In an embodiment of the present invention, when a severe fault occurs in the power grid, a disconnection request can be generated according to the load capacity that needs to be reduced (i.e., the target load capacity), and then the disconnection request is sent to the collaborative control system to perform the disconnection execution of multi-level dispatching interaction (i.e., the interaction between the provincial dispatching system, the local dispatching system, and the distribution dispatching system) through the collaborative control system.

[0041] Here, the coordinated control system is a system established to meet the requirements of the integrated precision load shedding function construction of the provincial, regional, and distribution systems. The coordinated control system includes: the provincial dispatching system, the regional dispatching system, and the distribution dispatching system. Moreover, data interaction based on the secure file transfer protocol is established among the provincial dispatching system, the regional dispatching system, and the distribution dispatching system to achieve the automatic execution of load shedding.

[0042] In the embodiment of the present invention, the provincial dispatching system is used to remotely control the line switches with voltages within the first preset voltage range (for example, 110 kV and above). After receiving a load shedding request, it can first determine whether the provincial dispatching system can complete the target load capacity carried by the load shedding request.

[0043] In the embodiment of the present invention, if the provincial dispatching system can complete the target load capacity carried by the load shedding request, it can directly perform load shedding through the provincial dispatching system. For example, after starting the load batch shedding module of the provincial dispatching system, it automatically selects and controls the shedding switches of the provincial dispatching system in the priority order in the load shedding sequence according to the target value (i.e., the target load capacity).

[0044] Step S102, in the case where the provincial dispatching system cannot complete the target load capacity, control the provincial dispatching system to decompose the load shedding capacity based on the target load capacity to obtain the load shedding decomposition capacity of each regional dispatching system. Here, the regional dispatching system is used to remotely control the whole-line switches with voltages within the second preset voltage range.

[0045] In the embodiment of the present invention, when the total load controllable by the provincial dispatching system is insufficient to meet the target load of the load shedding request, the load shedding capacity decomposition program will be automatically started, and the remaining load capacity gap will be decomposed according to the real-time total load of each regional dispatching system and the control ability of the regional dispatching system. The decomposed capacity is the load shedding decomposition capacity that each regional dispatching system needs to bear, and this capacity will guide the subsequent load shedding operations of the regional dispatching system.

[0046] Here, the regional dispatching system is responsible for remotely controlling the lines with voltages within the second preset voltage range (for example, 10 kV whole lines).

[0047] Step S103, control the provincial dispatching system to send an activation instruction to each regional dispatching system, and in the case where the regional dispatching system is successfully activated, control the provincial dispatching system to send a control instruction to the regional dispatching system. Here, the control instruction carries the load shedding decomposition capacity and the load shedding plan information.

[0048] In an embodiment of the present invention, after the provincial dispatching system determines the load shedding decomposition capacity of each local dispatching system, it can send an activation instruction to these local dispatching systems, set the "local dispatching control activation status" of this area in the area load shedding capacity table to 1, and send it to the local dispatching system through the measuring point forwarding method and read the activation status of the local dispatching system in real time. And the local control status and the local dispatching status can be respectively checked in the "control status" column and the "local dispatching status" column on the system interface of the provincial dispatching system to see if they are activated.

[0049] In an embodiment of the present invention, if the local dispatching system confirms receipt and successful activation, the provincial dispatching system will further send a control instruction, which carries the load shedding decomposition capacity and load shedding pre - plan information (that is, the pre - formulated strategy on how to control the load under specific conditions, including key information such as the order of load shedding and equipment selection). The local dispatching system will perform specific load shedding operations according to the received control instruction. For example, after the local dispatching system is successfully activated, the provincial dispatching system issues the load shedding pre - plan information and the target load through the "numerical value distribution" operation, updates the distribution time of this instruction, sets values for the "severe fault pre - plan information", "issued area load shedding capacity", and "issued area load shedding capacity time" in the "area load shedding capacity table" for this area and forwards these values to the local dispatching system.

[0050] Step S104, control the local dispatching system to perform load shedding based on the load shedding decomposition capacity and the load shedding pre - plan information.

[0051] In an embodiment of the present invention, after receiving the control instruction, the local dispatching system will start the load shedding operation according to the load shedding decomposition capacity and the load shedding pre - plan information. The local dispatching system will remotely control the whole - line switch to perform the opening operation, that is, cut off the power transmission, so as to achieve the target of reducing the power supply of the assigned load. At the same time, the local dispatching system will also send the information of the distribution network branch line switch to be controlled to the distribution dispatching system to further cooperate with the distribution dispatching system to perform more refined load control.

[0052] In summary, by intelligently decomposing the load capacity, when the provincial dispatching system faces a load capacity beyond its remote control ability, the decomposed load shedding decomposition capacity and the load shedding pre - plan information can be sent to the corresponding successfully activated local dispatching systems, and then the local dispatching systems are controlled to perform load shedding based on the load shedding decomposition capacity and the load shedding pre - plan information. This not only improves the accuracy of load shedding, but also can improve the execution efficiency of load shedding through the multi - level dispatching automatic interaction between the provincial dispatching system and the local dispatching system, achieving the technical effect of being able to perform efficient and accurate load shedding when a serious fault occurs in the power grid, and further solving the technical problem in the related art that the multi - level dispatching system cannot perform automatic interaction, resulting in a low execution efficiency of load shedding.

[0053] In order to accurately determine whether the provincial dispatching system can complete the target load capacity carried by the load shedding request, in the load shedding execution method based on multi-level dispatching interaction provided in the first embodiment of this application, the remote control load upper limit of the provincial dispatching system is determined; when the target load capacity is less than or equal to the remote control load upper limit, it is determined that the provincial dispatching system can complete the target load capacity, and the provincial dispatching system is controlled to execute load shedding; when the target load capacity is greater than the remote control load upper limit, it is determined that the provincial dispatching system cannot complete the target load capacity.

[0054] In the embodiment of the present invention, the remote control load upper limit of the provincial dispatching system can be determined first. The remote control load upper limit of the provincial dispatching system refers to the maximum load that the provincial dispatching system can directly reduce through remote control operations under the current power grid operation conditions. The determination of this upper limit takes into account the actual controllable load capacity of the high-voltage line switches directly dispatched by the provincial dispatching system (i.e., the lines within the first preset voltage range, such as lines of 110 kV and above) and the real-time operation state of the power grid, including but not limited to: the load levels of each line, equipment availability, etc.

[0055] In the embodiment of the present invention, when the target load capacity is less than or equal to the remote control load upper limit of the provincial dispatching system, the provincial dispatching system can directly complete the task of reducing power supply to the load through remote control operations. At this time, the provincial dispatching system can dispatch the high-voltage line switches to perform opening operations to cut the specified load.

[0056] Exemplarily, assume that the total load controllable by a certain provincial dispatching is L s , when the target capacity C to be controlled due to a serious fault is less than or equal to L s , then all the load shedding target C is allocated to the load shedding capacity index L of the provincial dispatching, and the provincial dispatching load batch load shedding module is started to automatically select and control the provincial dispatching load shedding lines in the order of priority according to the target value, without involving the local dispatching system.

[0057] In the embodiment of the present invention, if the remote control load upper limit of the provincial dispatching system is lower than the target load capacity of the load shedding request, this indicates that relying only on the resources of the provincial dispatching system cannot achieve the required load reduction target. At this time, the additional load reduction task can be decomposed to the lower-level dispatching system (local dispatching system) for execution to achieve the overall load control target.

[0058] In this embodiment, by clarifying the upper limit of the remotely controlled load of the provincial dispatching system, refined processing of the load shedding request is achieved. When the target load capacity is within the control range of the provincial dispatching system, load reduction can be quickly and independently completed, reducing the number of operation levels and time, and improving the emergency response efficiency. When the target load capacity exceeds the upper limit of the remotely controlled load of the provincial dispatching system, the load control task can be timely and intelligently decomposed to the local dispatching system. Through the collaborative work of multi-level dispatching, it is ensured that when the power grid faces a large power deficit or serious fault, the load control strategy can still be executed orderly and efficiently, guaranteeing the stable operation of the power system and minimizing the impact on people's livelihood electricity as much as possible.

[0059] In the method for executing load shedding based on multi-level dispatching interaction provided in the first embodiment of the present application, in order to improve the accuracy of determining the load shedding decomposition capacity of each local dispatching system, based on the load shedding request, determine the number of local dispatching systems involved in load shedding; determine the actual regional load of the area where each local dispatching system is located; based on the target load capacity and the upper limit of the remotely controlled load of the provincial dispatching system, determine the remaining load shedding capacity; based on the remaining load shedding capacity, the actual regional load and the number of local dispatching systems, calculate the load shedding decomposition capacity of each local dispatching system.

[0060] In the embodiment of the present invention, after receiving the load shedding request, the area involved in the power grid fault carried in the request can be analyzed to determine the number n of lower-level dispatching agencies (i.e., local dispatching systems) that need to participate in the load reduction operation. For example, through real-time monitoring of the power grid operation status, judge which areas of the power grid load need to be adjusted most to meet the overall power balance requirements.

[0061] In the embodiment of the present invention, the real-time power load data of the area controlled by each local dispatching system can be collected and analyzed to determine the actual regional load L of the area where each local dispatching system is located k , and, based on the target load capacity C and the upper limit of the load that can be reduced by the provincial dispatching system through remote control operation L s , the remaining load amount that needs to be reduced by the local dispatching system through load shedding operation can be calculated. Then, based on the remaining load shedding capacity, the actual regional load and the number of local dispatching systems, calculate the load shedding decomposition capacity C k of each local dispatching system. The calculation formula is as follows:

[0062]

[0063] Where k represents the kth local dispatching system, n represents the number of local dispatchings involved in the fault, and L k represents the total actual regional load of the kth local dispatching system.

[0064] In this embodiment, an intelligent and dynamic load control mechanism is constructed, which can quickly and accurately determine the number of participating units in the local dispatching system, the actual situation of regional load, and the allocation of the remaining load shedding capacity according to the real-time state of the power grid and the scale of the load shedding request. This mechanism realizes the reasonable calculation of the load shedding decomposition capacity through intelligent algorithms, not only improving the efficiency and accuracy of load control, but also ensuring that when the power system faces a large power deficit or serious faults, through the collaborative work of multi-level dispatching, the goal of quickly and smoothly achieving power balance can be achieved, reducing the impact on user power supply, and enhancing the anti-risk ability of the power grid in emergency situations.

[0065] In order to improve the accuracy of determining the actual regional load of the area where the local dispatching system is located, in the load shedding execution method based on multi-level dispatching interaction provided in the first embodiment of this application, the active power or current value transmitted by the switches of the same voltage level in the area where each local dispatching system is located is collected; the voltage value corresponding to the switch transmitting the current value is determined, and based on the current value, voltage value, and preset power factor, the active power corresponding to the current value is calculated; based on the active power of each switch in the area, the actual regional load of the area where the local dispatching system is located is determined.

[0066] In the embodiment of the present invention, through the real-time monitoring of the power grid, the active power P or current value I transmitted by all switches of the same voltage level (for example, 10 kV switches) in the control area of each local dispatching system can be obtained in real time. Then, for the switches that only transmit current values, the voltage values U corresponding to these switches can be further determined. Usually, the voltage value can be obtained from the real-time monitoring data or a fixed value can be preset according to the operating parameters of the power grid. After that, according to the current value I, voltage value U, and preset power factor cosθ, the active power P corresponding to the current value is calculated, and the calculation formula is as follows:

[0067]

[0068] Where P is the active power, cosθ is the power factor, which is usually taken as 0.98 empirically, U is the voltage, and I is the real-time value of the current.

[0069] In the embodiment of the present invention, the active powers of the power supply side switches of the same voltage level in the area obtained by collection and calculation can be summarized to obtain the actual regional load in the control area of each local dispatching system.

[0070] In this embodiment, by determining the actual load levels of each region in real time, not only the intelligent level of power dispatching is improved, but also the science and fairness of load shedding operations are ensured, which helps to quickly identify and control the load in emergency situations such as power supply and demand imbalance or power grid faults, guarantee the stable operation of the power system, and reduce the impact on user power supply.

[0071] Optionally, the control instruction also carries the issuing time. To accurately determine whether the local dispatching system is in a pending execution state, in the power outage execution method based on multi-level dispatching interaction provided in the first embodiment of this application, after the provincial dispatching system sends a control instruction to the local dispatching system, determine whether the duration between the current time of the local dispatching system and the issuing time exceeds a preset duration threshold; when the duration between the current time of the local dispatching system and the issuing time does not exceed the preset duration threshold, based on the power outage plan information, check the remote control status of each switch to be remotely controlled, where the power outage plan information includes: a plurality of switches to be remotely controlled; when the remote control status of each switch to be remotely controlled is in a normal state, determine that the local dispatching system is in a pending execution state.

[0072] In an embodiment of the present invention, after receiving the activation status, plan information, power outage capacity, and issuing time sent by the provincial dispatching system, the local dispatching system can verify whether the issuing time and the current time of the local dispatching system exceed the effective range (that is, determine whether the duration between the current time of the local dispatching system and the issuing time exceeds a preset duration threshold, and this preset duration threshold is used to ensure the timeliness of the power outage instruction and ensure that in an emergency where the power grid conditions change rapidly, the power outage operation can be responded to in a timely manner). If the difference between the time when the local dispatching system receives the instruction and the issuing time exceeds this threshold, it is regarded that the instruction is invalid or delayed, and the local dispatching system should not continue to execute. If it is confirmed that the time difference does not exceed the preset duration threshold, the local dispatching system will, based on the received power outage plan information (including: a plurality of switches to be remotely controlled,), check the current remote control status of all switches to be remotely controlled in the power outage plan information one by one (the remote control status is the status of whether the switch can be operated by the remote control system, including but not limited to whether it has a remote control point number channel, whether there is an indication prohibiting remote control, whether the remote signal status is normal, etc.), to ensure that these switches are in a normal state where they can be remotely controlled, so as to prepare for the power outage operation. After the local dispatching system completes the verification of the remote control status of all switches to be remotely controlled and confirms that all switches are in a state where they can be normally remotely controlled, it will automatically enter the pending execution state, ready to receive and execute the control instruction of the provincial dispatching system, that is, perform the power outage operation.

[0073] In some optional embodiments, after the above verification is passed, a confirmation window can be popped up in the local dispatching system. If the monitoring status of the window shows "the current instruction has been confirmed", it means that the issuing time is valid and the plan information is correct. Then, after the measurement status on the verification interface is normal, the control interface can be started, the "current control status" in the "provincial-local integrated load batch control" is set to "controlling", and forwarded to the provincial dispatching system. The provincial dispatching system automatically synchronously updates the "current local dispatching control status" in the "regional outage capacity table" to "controlling".

[0074] In this embodiment, the timeliness of the instruction is ensured through time calibration, avoiding control failure caused by time delay. Moreover, by checking the status of the remote control switch, it is ensured that all devices participating in the line switching are in normal working condition, avoiding load control errors caused by operation failure. Finally, after confirming that all conditions are met, the local dispatching system enters the pending execution state, which not only improves the efficiency of the line switching operation but also ensures the safety and accuracy of the operation.

[0075] Optionally, the line switching plan information further includes: the sequence number of each remote control switch to be controlled and the switch identifier of each remote control switch. When the switch identifier is a branch line switch identifier, the switch identifier corresponds to a main network identifier of the switch. When the switch identifier is a whole line switch identifier, the main network identifier corresponding to the switch identifier is empty. To accurately execute the line switching, it is necessary to perform verification before executing the line switching. In the line switching execution method based on multi-level dispatching interaction provided in Embodiment 1 of the present application, after the control provincial dispatching system sends a control instruction to the local dispatching system, when the local dispatching system is in the pending execution state, based on the sequence number of each remote control switch to be controlled, verify whether the switch identifier and the main network identifier of each remote control switch are consistent with the local switch identifier and the local main network identifier in the local switch information stored in the local dispatching system; when the switch identifier and the main network identifier of each remote control switch are consistent with the local switch identifier and the local main network identifier in the local dispatching system, control the local dispatching system to execute the line switching.

[0076] In the embodiment of the present invention, the line switching plan information includes the detailed information of each remote control switch to be controlled, specifically the sequence number (used to determine the priority order of each remote control switch in the line switching operation to ensure the orderly progress of the operation) and the switch identifier. In addition, to distinguish different types of switches, the plan information also stipulates that when the switch is a distribution network branch line switch, its associated main network power supply identifier should be attached; while when the switch is a whole line switch, the main network power supply identifier does not need to be provided because such a switch itself is a part of the main network.

[0077] In the embodiment of the present invention, after the provincial dispatching system issues a line switching control instruction to the lower-level local dispatching system, the local dispatching system enters the pending execution state. At this time, the local dispatching system needs to verify the sequence number, switch identifier, and the main network identifier of the branch line switch of the remote control switch in the line switching plan information to ensure that these information are completely matched with the local switch information stored in the local dispatching system database. This verification process is a key safety check before the line switching operation, which can avoid misoperation caused by information errors. If the local dispatching system completes the verification and confirms that the plan information is consistent with the local switch information, the line switching operation can be executed. This operation process follows the sequence number specified in the line switching plan, first remotely opens the whole line switch, and then performs the same operation on the branch line switch until the target load is met.

[0078] In this embodiment, by adding detailed switch identifiers and main network identifiers to the power outage plan information and performing strict information verification before the execution of the substation dispatching system, not only the safety and accuracy of the power outage operation are ensured, but also the operation efficiency and speed are improved through the introduction of an automated process. In this way, when the power system faces a major load imbalance or fault, the corresponding switch equipment can be quickly and accurately located and controlled, effectively avoiding the further deterioration of parameters such as frequency and voltage, which is an effective measure to underpin the stable operation of the power system.

[0079] To improve the accuracy of power outage execution, in the power outage execution method based on multi-level dispatching interaction provided in Embodiment 1 of this application, the substation dispatching system is controlled to generate a list of branch switch controls based on the power outage plan information, where the list of branch switch controls includes: multiple branch switch identifiers; the substation dispatching system sends the list of branch switch controls to the distribution dispatching system, where the distribution dispatching system is used to remotely control the branch switches under the entire line whose voltage belongs to the second preset voltage range; the substation dispatching system remotely controls the power outage of each entire line indicated by each entire line switch identifier based on the power outage plan information, and controls the distribution dispatching system to perform the power outage of each branch line indicated by each branch switch identifier based on the list of branch switch controls.

[0080] In the embodiment of the present invention, the substation dispatching system can screen out all the distribution network branch switches participating in the power outage operation according to the power outage plan information and generate a detailed list of branch switch controls. This list contains the identification information of all the distribution network branch switches to be remotely controlled, providing a specific target for the subsequent operation of the distribution dispatching system. After generating the list of branch switch controls, the substation dispatching system can send this list to the distribution dispatching system through a data interaction protocol. The distribution dispatching system is responsible for receiving and processing this list, and then remotely controls the distribution network branch switches under the entire line with a voltage in the second preset voltage range (for example, 10 kV) to perform the power outage operation.

[0081] In the embodiment of the present invention, after the information interaction between the substation dispatching system and the distribution dispatching system is completed, the substation dispatching system remotely controls the switch of the corresponding entire line according to the entire line switch identifier in the power outage plan information to perform the power outage operation. Moreover, the distribution dispatching system performs the power outage of each branch line listed in the received list of branch switch controls to achieve the coordinated control of the entire line and the distribution network branch line.

[0082] In this embodiment, a multi-level and collaborative power system control network is constructed, which not only improves the efficiency and accuracy of load shedding operations, but also achieves precise control of the main line and distribution network branch lines, reduces the impact on power supply in non-target areas, and improves the response speed and handling ability of the power grid in emergency situations. In addition, by introducing an automated process, the possibility of human error is reduced, further enhancing the stability and security of the power system operation.

[0083] In some optional embodiments, after the load shedding operation of the local dispatching system is completed, click "Exit Interface" on the control confirmation interface of the local dispatching system, and set the current control status in "Provincial-Local Integrated Load Batch Control" to "Control Completed" and send it to the provincial dispatching system. The provincial dispatching system synchronously updates the "Local Dispatching Current Control Status" in the "Regional Cut Capacity Table" to "Control Completed". If the provincial dispatching system clicks "Cancel Activation" before the load shedding is executed, an instruction will be issued to cancel the current load shedding operation and forwarded to the local dispatching system, and at the same time, the local dispatching system will be restored to the activated state. Moreover, after the local dispatching control is completed, the provincial dispatching system can issue a reset signal instruction to reset the activation state to non-activated, set the pre-plan information to an abnormal value, set the target load to 0, and set the sending time to 0, indicating that a complete batch control operation has ended, and the collaborative control system can standby for the next operation.

[0084] The following will be described in detail in combination with another optional specific implementation manner.

[0085] To meet the requirements of the construction of the provincial-local-distribution integrated precise load shedding function, data interaction based on the Secure File Transfer Protocol is established among the provincial dispatching system, local dispatching system, and distribution dispatching system. The provincial dispatching system can send the load shedding capacity index to the local dispatching system. To ensure the timely and accurate transmission of the load reduction target, relevant measurement information can be automatically supplemented, specifically including: the activation status, sending time, current control mode, cut target capacity, current control status sent from the provincial dispatching to the local dispatching, the total controlled capacity and load batch control status sent from the local dispatching to the provincial dispatching, etc. In addition, the local dispatching system will also obtain the branch load switch model data, branch load real-time measurement data, and control results from the distribution dispatching system and forward them to the provincial dispatching system. When the local dispatching system and the distribution dispatching system cooperate, the local dispatching system forms a branch switch control list according to the load shedding sequence of the main and distribution network mixed arrangement and sends it to the distribution dispatching system, and the distribution dispatching system executes the rapid batch excision of the distribution network branch switches. During this control process, the distribution dispatching system generates a control process interaction file and sends it to the local dispatching system regularly (such as every 30s). In the actual control interaction process of the main and distribution networks, the local dispatching system monitors and verifies the control status file sent by the distribution dispatching system in real time, and timely identifies control interaction interruptions and timeouts. In case of control anomalies and other situations, the distribution dispatching system will also feedback to the local dispatching system and inform the dispatcher in the form of alarms or changes in the status indicator lights on the screen.

[0086] Figure 2 It is a schematic diagram of an optional provincial - local - distribution collaborative control process according to an embodiment of the present invention. As Figure 2 shown, the provincial dispatching system can send the load shedding target to the local dispatching system. The local dispatching system can send the control sequence list to the distribution dispatching system. The distribution dispatching system can send the branch load switch model data, branch load real - time measurement data, control execution confirmation, control result, and control process to the local dispatching system. Then, the local dispatching system can send the branch load switch model data, branch load real - time measurement data, and control result to the provincial dispatching system.

[0087] Figure 3 It is a schematic diagram of an optional local - distribution collaborative control process according to an embodiment of the present invention. As Figure 3 shown, the local dispatching system can send the control sequence list file (including distribution network branch switches) to the distribution dispatching system, and the distribution dispatching system can send the control execution confirmation file, control process file, and control result file to the local dispatching system.

[0088] In the embodiment of the present invention, the load - shedding execution method based on multi - level dispatching interaction realizes efficient collaboration among the provincial dispatching, local dispatching, and distribution dispatching by intelligently decomposing the load capacity. It not only improves the load - shedding efficiency, enhances the flexibility and accuracy of dispatching, but also ensures the safety and stability of the power grid operation.
