Description

Power grid operation plan scheduling method, system, terminal equipment and storage medium

Technical Field

The present application relates to the technical field of smart power grids, and in particular, to a power grid operation plan scheduling method, a system, a terminal device, and a storage medium.

Background

The power grid operation plan release schedule refers to a process of generating and releasing a power grid operation plan according to a predicted load, an available power source and other power grid operation conditions in a power system. This process is typically responsible for the grid operator or system operator. Meanwhile, the grid operation plan release schedule needs to consider various factors including supply and demand balance of the power system, transaction arrangement of the power market, operation limitation of the power equipment and the like. At the same time, scheduling and control capabilities of the power system, as well as handling measures in emergency situations, need to be taken into account.

At present, in the process of carrying out power grid operation by scheduling and field connection, the current power grid operation progress situation is mainly released in a mode of operation plan release, and the method is an important way for field personnel to know the overall power grid operation progress and predict the self operation time. It mainly comprises two modes: firstly, the scheduling informs the corresponding field personnel of the operation information through telephone, and the specific operation progress and arrangement are manually judged by the scheduling; and secondly, the software predicts the time of each field operation according to the information of the operation ticket and the maintenance ticket. In the software prediction process, the current prediction mode generally comprises the following steps: firstly, a dispatcher estimates the duration of specific field operation of each type of equipment according to historical experience; and then, calculating the planned operation starting time of each ticket in the operation ticket according to the planned working time and the planned completion time of the overhaul application form and the accumulated operation duration of the operation instructions, and issuing the planned operation starting time on the website by taking the time as the operation plan of each station.

In practical applications, in the above mode, there are some problems: (1) The execution time of the operation instruction is given by a dispatcher according to historical experience, and in practice, according to the types of transformer substations, equipment and the like, relatively large deviation exists among various operations, so that the time arrangement is unreasonable; (2) The current preset operation time is calculated according to the maintenance ticket associated with the operation ticket, but is not associated with the actual work load of the dispatching desk, and different operation tickets are not associated with each other; (3) After the operation ticket is delayed, the expected operation time of the operation ticket is only delayed to the current state, which is not reasonable, and the actual latest operation information is not visible at the rear side, so that the issuing scheduling effect of the power grid operation plan is poor.

Detailed Description

The application is described in further detail below with reference to fig. 1-8.

The embodiment of the application discloses a power grid operation plan scheduling method, as shown in fig. 1, comprising the following steps:

s101, acquiring an operation instruction corresponding to a dispatching center;

s102, if the operation instruction has a historical repeated operation instruction, acquiring an average value of execution time periods corresponding to the historical repeated operation instruction as a predicted execution time period of the operation instruction;

s103, if the operation instruction does not have the historical repeated operation instruction, carrying out operation record retrieval of the same type on the operation instruction, and generating predicted execution time of the operation instruction according to a retrieval result;

s104, generating a corresponding scheduled operation plan by combining the operation association relation, the operation priority and the predicted execution time length corresponding to the operation instruction;

s105, performing deferred risk assessment on a predetermined scheduling operation plan, generating corresponding deferred assessment data, and generating corresponding deferred dynamic update information according to the deferred assessment data;

s106, combining a preset scheduling operation plan and deferred dynamic update information to generate a corresponding operation plan schedule.

In step S101, the dispatching center refers to a power grid dispatching desk, which is a core control center for operation of the power system and is responsible for monitoring and controlling the operation states of the power system in real time, including the operation states and parameters of various power grid devices such as a generator set, a transmission line, a transformer substation, and the like. The dispatching desk monitors and analyzes the operation data of the power grid equipment to carry out load dispatching and resource optimization, so that the stable operation of the power system is ensured.

Secondly, after determining the operation measures to be taken, the dispatching center issues corresponding operation instructions. These instructions are typically issued orally or in written form to the various grid operations departments and operators. The dispatch center will determine the content, execution time and place, etc. of the instructions and ensure that the operator understands and follows the instructions.

In step S102, the historical repetitive operation instructions refer to that the same or similar operation instructions occur in the past grid operation records, and these operation instructions may be issued and executed by the same operation staff or system automation program under similar load conditions or under similar operation environments.

Wherein the type and parameters of the historical repetitive operation instruction and the current operation instruction should be similar or matched to be considered as the historical repetitive operation instruction. For example, if the current operating command is a command to adjust generator output power, then the historical repetitive operating command should be the same or similar command to adjust generator output power.

Next, the execution duration of the history of repeated operation instructions refers to the time required for the same or similar operation instructions to complete in the past operation. By recording the execution duration of the historical repetitive operation instruction, a reference value can be obtained for predicting the execution duration of the current operation instruction. For the execution duration of a plurality of historical repeat operation instructions, their average may be calculated to obtain an average predicted execution duration. In this way, the execution time of the current operation instruction can be estimated more accurately, and a reference for grid operation and scheduling is provided. The predicted execution time of the operation instruction means the time from when the schedule notifies the field personnel of the instruction information to when the field operation is completed.

For example, the operation instruction mainly includes two key parts of equipment and state change, such as "change the eastern security 5233 switch from running to hot standby", the eastern security 5233 switch is equipment, the change of state is described when the eastern security 5233 switch is changed from running to hot standby, and if the history instruction has the instruction content identical to the eastern security 5233 switch, the average value of the corresponding execution time of the instruction content of the part is taken as the predicted execution time of the operation instruction.

In step S103, if the current operation instruction does not have a history of repeated operation instructions available for reference, a search of the same type of operation record may be performed, and a predicted execution duration of the operation instruction may be generated according to the search result. For example, if the operation instruction is not identical to the operation instruction, all similar switch operations in the substation range governed by the operation and maintenance class corresponding to the operation instruction can be searched, that is, the average time length of all operations of converting the operation of the switch into hot standby, and if the operation instruction exists, the time length of the operation is taken as the predicted execution time length.

In step S104, the operation association relationship refers to the mutual influence and the dependency relationship between different operation instructions. For example, some of the operation instructions may need to be performed after other operation instructions are executed. These associations need to be considered when generating a predetermined scheduling operation plan to ensure that the operation instructions proceed in the correct order and logic to avoid collisions and problems.

Wherein, the operation priority refers to the importance and the emergency degree among different operation instructions. Based on the priority of the operation instructions, the order of their execution in the dispatch plan may be determined. The operation instruction with high priority will be executed with priority to ensure that its importance and urgency are satisfied. The operation priority can be set according to the running requirement and the safety requirement of the power grid and is considered together with the operation association relation to generate a reasonable scheduling plan.

And secondly, the predicted execution time is the execution time of the operation instruction estimated according to the historical repeated operation instruction or the data of the same type of operation record. When generating a predetermined scheduled operation plan, the predicted execution time length may be combined with the operation association and the operation priority to determine the specific execution time of the operation instruction in the plan. Longer predicted execution durations may require prioritization to ensure that the operation instructions can be completed in time without affecting the performance of subsequent operations.

Further, the operation association relation, the operation priority and the predicted execution duration of the operation instruction are comprehensively considered and combined, and a predetermined scheduling operation plan can be generated. The program will ensure that the operating instructions are performed in the correct order and time to meet the demands and requirements of the grid operation. Meanwhile, according to actual conditions, the scheduled scheduling operation plan may also need to be adjusted and optimized according to real-time data and conditions so as to ensure stable operation and safety of the power grid.

It should be noted that the predetermined scheduling operation plan may be a schedule or a time table, which includes information such as execution time, order, and priority of each operation instruction. Through a preset scheduling operation plan, the execution of operation instructions can be reasonably arranged and organized, operation conflict and competition are avoided, the operation instructions are ensured to be carried out according to a correct sequence, and problems and risks in power grid operation are reduced to the greatest extent. In addition, the formulation of the predetermined scheduling operation plan needs to comprehensively consider a plurality of factors including the association relation between operation instructions, the priority of the operation, the predicted execution time length and the like. By analyzing and evaluating these factors, the order and timing of execution of the operational instructions can be determined, thereby generating a rational dispatch plan. In addition, the scheduled operation plan should be dynamically adjusted and optimized according to real-time data and conditions to adapt to actual requirements and changes of the power grid operation.

In step S105, the deferred risk assessment evaluates the scheduled scheduling operation plan, analyzes factors that may cause a plan to be deferred, and generates corresponding deferred assessment data. Delay evaluation data is data obtained by evaluating and analyzing factors possibly causing delay of a scheduled scheduling operation in a scheduled scheduling operation. These factors may include, but are not limited to: the execution time of the operation instructions exceeds the predicted time length, unavoidable conflicts between the operation instructions, interference of external factors, and the like. By evaluating and analyzing these factors, delay evaluation data can be derived for evaluating the delay risk of a predetermined dispatch operation plan.

The delay dynamic update information is update information generated according to delay evaluation data and is used for dynamically adjusting and updating a preset scheduling operation plan. From the deferral evaluation data, it may be determined which operational instructions may present a risk of deferral, as well as the cause and possible impact of the deferral. Based on this information, the scheduled scheduling operation plan may be dynamically updated, such as to reorder the execution order of the operation instructions, adjust the priority of the operation instructions, etc., to minimize delay risks and ensure stability and safety of grid operation.

For example, when a delay occurs in the scheduling operation, if suspension is not needed, the first delay is 1/2 of the normal operation duration, and all the affected operation units are prompted: since the A-phase operation is delayed, it is necessary to delay execution for about 20 minutes. Wherein no suspension is required means that although the execution time of the scheduling operation is delayed, no other operations or processes need to be suspended or suspended. Even if the scheduling operation is not performed according to the scheduled time, other operations can still be continued without being affected by the delay of the scheduling operation.

The delay may be caused by various reasons, such as insufficient resources, delay of a front-end task, technical problems, and the like. In some cases, if a scheduled operation delay occurs, it may be necessary to suspend other operations or processes to ensure the order and dependencies of the operations. However, if in some case the deferral of the scheduled operations does not have a significant impact on other operations, then other operations may continue without having to pause or abort them.

It should be noted that, the delay risk assessment and the delay dynamic update information are used to cope with possible delay situations in the scheduled operation plan, so as to ensure the continuity and stability of the operation of the power grid. By evaluating and analyzing the delay risk and dynamically updating according to the evaluation result, the delay risk can be timely handled, and adverse effects on the operation of the power grid caused by planning delay are avoided. Meanwhile, in actual operation, the delay dynamic update information can be adjusted and optimized according to real-time data and conditions so as to adapt to actual requirements and changes of power grid operation.

In step S106, the operation plan schedule is a time-sequentially scheduled operation instruction execution plan generated based on the scheduled operation plan and the deferred dynamic update information. It is the result of dynamically adjusting and updating the scheduled scheduling operation plan according to the actual situation, taking into account the risk of postponements.

Specifically, firstly, according to a predetermined scheduling operation plan, determining information such as execution sequence, time and priority of operation instructions; then, according to the delay dynamic update information, evaluating and analyzing factors possibly causing delay in a predetermined scheduling operation plan, and determining the delay risk degree; secondly, dynamically adjusting and updating a predetermined scheduling operation plan according to the deferred risk assessment result, for example, rearranging the execution sequence of operation instructions, adjusting the priority of the operation instructions and the like so as to reduce the deferred risk; and finally, according to the updated scheduled operation plan, scheduling execution of the operation instructions according to a time sequence to form an operation plan schedule.

It should be noted that the purpose of the operation plan scheduling is to ensure that the operation instructions are performed in the correct order and time to meet the requirements and demands of the grid operation and minimize the delay risk. By comprehensively considering the scheduled operation plan and the delayed dynamic update information, the operation plan schedule can be flexibly adjusted and optimized in actual operation so as to adapt to the change and the requirement of the power grid operation.

According to the power grid operation plan scheduling method provided by the embodiment, whether the current operation instruction has the historical repeated operation instruction is judged, if yes, the average value of the execution time length of the historical repeated operation instruction is directly used as the predicted execution time length of the operation instruction, so that the influence of the dispatcher experience on the operation instruction time length can be reduced, the accuracy of operation instruction execution time length prediction is further improved, then delay risk assessment is carried out on the preset scheduling operation plan generated by the operation instruction, corresponding delay dynamic update information is generated, relevant units and personnel involved in delay can be dynamically and reasonably notified according to the delay dynamic update information when operation delay occurs, unnecessary waiting of on-site operators is reduced, and accordingly the scheduling effect of power grid operation plan release is improved.

In one implementation manner of this embodiment, as shown in fig. 2, after step S101, that is, after obtaining the operation instruction corresponding to the dispatch center, the method further includes the following steps:

s201, if the operation instruction is an overhaul instruction, acquiring a corresponding overhaul bill according to the overhaul instruction, and analyzing the overhaul bill to generate a corresponding operation ticket;

s202, if the operation ticket is a stop operation, sequencing all stop operations according to the start time and stop operation steps listed by the operation ticket, and generating a corresponding stop time shaft, wherein the stop time shaft comprises a time period corresponding to each operation in the stop operation steps and the operation number in each time period;

s203, if the number of operations in the same time period exceeds the bearing capacity of the dispatching desk, advancing the starting time of the key operation according to the priority order of the operation ticket, so that the finishing time of all the decommissioning operations is before the maintenance work related to the decommissioning operations is started.

In step S201, the service ticket is a file describing the contents of the service work in detail, and includes information of the working range, the operation steps, safety precautions, required tools and equipment, etc. The operation ticket is an operation instruction file generated according to the maintenance list and is used for guiding an actual operator to carry out maintenance work.

In step S202, if the operation ticket is a shutdown operation, all the shutdown operations may be ordered according to the start time according to the shutdown operation steps and the start time listed in the operation ticket. Operation in the planned order is ensured in order to achieve an effective outage plan. And generating a time axis of the outage according to the sequenced outage operation. The time axis is a time-ordered chart showing the time period and number of out-of-service operations. Wherein, on the out-of-service time axis, each out-of-service operation step corresponds to a time period, indicating that the operation is performed during the time period. At the same time, the number of operations per time period, i.e. the number of operations to be performed during the time period, is also recorded. Meanwhile, the operation amount at the same time is required to be in the bearing capacity range of the dispatching desk.

Wherein, based on the operation plan forecast of the dispatching desk load, all relevant operation tickets can be acquired according to the maintenance list, and the start time of the decommissioning operation can be forecast according to the planned maintenance work start time and the planned maintenance work end time.

For example, the out-of-service timeline includes, time period 1: operation A, operation B and operation C, wherein the number of operations is 3; time period 2: operation D and operation E, wherein the number of operations is 2; time period 3: operation F, operation G, operation H, number of operations 3. Wherein the generation of the out-of-service timeline may facilitate the planning and management of out-of-service operations. By clearly showing the operations and the number of operations in each time period, it is possible to help organize and coordinate out-of-service work, ensure scheduled performance, and ensure that the order and number of operations are reasonably arranged and controlled. In addition, the downtime axis may also be used in coordination with other related tasks to ensure that the entire downtime process proceeds smoothly.

In step S203, if the number of operations within the same time period exceeds the carrying capacity of the dispatch table, the start time of the critical operations needs to be advanced according to the priority order of the operation ticket to ensure that all out-of-service operations are completed before the associated maintenance work starts. Thus, smooth progress of the outage plan can be ensured, and congestion and delay in the operation process are avoided. The priority order of the operation tickets is mainly the order according to the accident handling ticket > power outage operation > power transmission operation > starting operation.

In terms of priority order, the operation ticket generally assigns a priority to each operation, which indicates importance or urgency, and determines which operations are critical operations and need priority processing according to the priority order of the operation ticket. The front-off start time is to advance the start time of the key operation according to the priority order of the key operation, so that the key operation can be ensured to start early, finish in advance, and make time for the subsequent operation.

Second, after advancing the critical operation start time, the scheduling of other operations needs to be readjusted to ensure that the completion time of all decommissioning operations is before the associated overhaul job begins. Therefore, maintenance work can be ensured to be started according to a plan, other operation works are prevented from being delayed and influenced, and the order of the out-of-service operation can be reasonably arranged by advancing the starting time of key operation, so that the efficiency is improved to the greatest extent and the safety is ensured.

According to the power grid operation plan scheduling method, the scheduling table bearing capacity is considered, and meanwhile, the shutdown operations are ordered and optimized, so that the starting time of the related operation of the shutdown can be more reasonably arranged, the conflict and overlapping of the shutdown operations are reduced, and the execution efficiency of the shutdown operations is improved.

In one implementation manner of this embodiment, as shown in fig. 3, in step S201, if the operation instruction is a maintenance instruction, the steps further include the following steps after acquiring a corresponding maintenance order according to the maintenance instruction and analyzing the maintenance order to generate a corresponding operation ticket:

s301, if the operation ticket is a re-service operation, sequencing all re-service operations according to the start time and the re-service operation steps listed by the operation ticket, and generating a corresponding re-service time shaft, wherein the re-service time shaft comprises a time period corresponding to each operation in the re-service operation steps and the operation number in each time period;

s302, if the number of operations in the same time period exceeds the bearing capacity of the dispatching desk, the starting time of the secondary operation is shifted backwards according to the priority order of the operation ticket, so that the starting time of all the re-service operations is after the maintenance work associated with the re-service operation is finished.

In step S301, if the operation ticket is a re-service operation, all re-service operations may be ordered according to the start time and the re-service operation step of the operation ticket, and a corresponding re-service time axis may be generated. The re-service time axis includes an operation time period in each re-service operation step and the number of operations within each time period.

The sequencing and re-service operation is to sequence all re-service operations according to the start time and the re-service operation steps and the start time listed in the operation ticket, so as to ensure that the operations are performed according to the planned sequence, and realize an effective re-service plan. And generating a re-service time shaft according to the sequenced re-service operation. The time axis is a time-ordered chart showing the time period and number of operations for a re-service operation. On the re-service time axis, each re-service operation step corresponds to a time period, which means that the operation is performed in the time period. At the same time, the number of operations per time period, i.e. the number of operations to be performed during the time period, is also recorded.

Second, the generation of the re-service timeline may facilitate planning and management of re-service operations. By clearly showing the operations and the number of operations in each time period, it is possible to help organize and coordinate the re-commissioning work, ensure that the scheduled operations are performed, and ensure that the order and number of operations are reasonably arranged and controlled. In addition, the re-service time axis can also be used for coordination with other related tasks to ensure that the entire re-service process proceeds smoothly.

In step S302, if the number of operations within the same time period exceeds the carrying capacity of the dispatch table, the start times of the secondary operations may be adjusted according to the priority order in the operation ticket to ensure that the start times of all the re-service operations are after the end of the related maintenance work.

In particular, the operation ticket will typically give priority to the operations, i.e. which operations are primary and which are secondary. The primary operation is generally a critical task that must be completed within a specific time, while the secondary operation is relatively less urgent. The start time of the secondary operation is then shifted back according to the priority order until the carrying capacity of the scheduler is no longer exceeded, which ensures that the primary operation is prioritized for a predetermined time, while the secondary operation is deferred until a later time period.

Wherein the purpose of adjusting the start time of the secondary operation to be shifted backward is to ensure that the start time of all re-service operations is after the end of the associated service work. Therefore, operation conflict can be avoided, and smooth execution of re-service work is ensured. By adjusting the start time of the secondary operation, the execution time of the secondary operation can be reasonably arranged while ensuring the priority processing of the primary operation, and the situation that the bearing capacity of the dispatching desk is exceeded is avoided. Therefore, the efficiency and the safety of the re-service work can be improved to the greatest extent.

According to the power grid operation plan scheduling method, the bearing capacity of the scheduling table is considered, and the starting time of the secondary operation is shifted backwards according to the priority sequence of the operation ticket, so that the secondary operation can be ensured to be carried out after the maintenance work is finished, and the priority management level of the re-service operation is improved.

In one implementation manner of the present embodiment, as shown in fig. 4, in step S201, if the operation instruction is a maintenance instruction, the steps of obtaining a corresponding maintenance order according to the maintenance instruction, analyzing the maintenance order to generate a corresponding operation ticket further include the following steps:

s401, if the operation ticket is scheduled, checking the operation ticket according to a preset operation ticket checking strategy, and generating a corresponding checking result;

s402, if the checking result is abnormal, recalculating the operation ticket according to the priority order of the operation ticket, adjusting the scheduling to generate a corresponding correction operation ticket, and notifying all clients currently on line to update according to the correction operation ticket.

In step S401, the preset operation ticket checking strategy is a series of checking steps and criteria formulated according to the scheduling requirement and the design requirement of the operation ticket, and these steps and criteria are used to evaluate the completion condition and quality of the operation ticket, so as to ensure that the operation ticket meets the expected requirement; according to a preset operation ticket checking strategy, checking the operation tickets item by item, wherein the checking comprises checking the integrity of operation steps, the rationality of operation time, the correctness of operation sequence and the like. At the same time, it is also possible to check whether the key information in the ticket is consistent with other related documents or requirements.

And generating a corresponding investigation result report according to the investigation result. The report may list the troubleshooting items and troubleshooting results for each ticket, including portions that are satisfactory, unsatisfactory, and require further adjustment. The screening results may also include advice and improvement comments on the ticket to improve ticket quality and compliance. The purpose of the investigation is to ensure consistency of the content and schedule of the ticket in order to achieve an effective re-service plan.

Secondly, by checking the operation ticket, the problems and inconsistencies in the operation ticket can be found and corrected in time, and the accuracy and the executable performance of the operation ticket are ensured. The generation of the investigation result can help to organize and manage the re-service work, ensure to be carried out according to the plan, and improve the efficiency and ensure the safety to the greatest extent.

In step S402, the result of the investigation shows that the operation ticket is abnormal, which may be a problem of an operation step error, an operation time conflict, an improper operation sequence, or the like. The result of the abnormality investigation is recorded and used as the basis for correcting the operation ticket. And setting a priority order according to factors such as importance, urgency and the like by the operation ticket, and recalculating and adjusting scheduling the abnormal operation ticket according to the priority order so as to ensure that important operations are executed preferentially.

And secondly, generating a correction operation ticket based on the result of the recalculation and the scheduling adjustment. The correction operation ticket is correspondingly modified according to the checking result, so that the operation steps, time, sequence and the like meet the requirements, and the accuracy and the effectiveness of the operation are ensured. Once the correction operation ticket is generated, all clients currently online need to be timely notified to update. The notification can be sent to the client by means of system messages, mails, short messages and the like, and reminds the client to update the operation ticket to acquire the latest scheduling information.

For example, a timing task is set, whether deviation occurs in the operation ticket is calculated every ten minutes, the operation of scheduling is automatically recalculated, and when the operation is changed, all clients currently on line are notified to update.

It should be noted that, by recalculating and adjusting the schedule, a correction operation ticket is generated and the client is notified to update, so that the abnormal operation ticket can be ensured to be corrected and updated in time, so as to avoid operation errors and conflicts, and ensure smooth operation. Meanwhile, the client is informed of updating the operation ticket in time, so that all related personnel can obtain the latest operation plan, and confusion and errors caused by inconsistent operation tickets are avoided.

According to the power grid operation plan scheduling method, errors or anomalies in the operation ticket can be corrected in time, the accuracy of the operation ticket is improved, meanwhile, the current online client side is informed to update according to the corrected operation ticket, all persons using the operation ticket can be ensured to acquire the latest operation ticket information in time, and the instantaneity and accuracy of the operation ticket are improved.

In one implementation manner of the present embodiment, as shown in fig. 5, step S103, that is, if the operation instruction does not have a historical repeated operation instruction, performs the operation record search of the same type on the operation instruction, and generates the predicted execution duration of the operation instruction according to the search result includes the following steps:

s501, if the operation instruction does not have a history repeated operation instruction, acquiring a search result corresponding to the operation record search of the same type;

s502, if the search result shows that the similar operation instructions exist, taking an average value of the execution time lengths corresponding to the similar operation instructions as the predicted execution time length of the operation instructions;

s503, if the search result is that the similar operation instructions do not exist, matching operation experience records corresponding to the operation instructions, and taking the execution duration experience values in the operation experience records as the predicted execution duration of the operation instructions.

In step S501, when the history operation record is searched in the system, it is found that the current operation instruction has not repeatedly appeared. This means that the instruction has not been executed in the past operation record or has not been the same operation instruction as it. In order to improve the objectivity of the operation instruction corresponding to the predicted execution duration, the same type of operation record corresponding to the operation instruction can be further obtained, wherein the same type of operation record refers to a historical record with the same or similar operation content as the current operation instruction. For example, if the current operation instruction is an instruction to "change eastern security 5233 switch from operation to hot standby", then the same type of operation record is an operation record associated with all jurisdictional grid devices "change switch from operation to hot standby".

By acquiring the operation records of the same type, a set of history records similar to the current operation instruction can be obtained. These records may contain information about time of operation, operator, results of the operation, etc., for reference and comparison.

In step S502, by acquiring the search result of the operation record of the same type, which has a history similar to the current operation instruction, exists. These records contain information about the execution time of the same type of operation instruction. For a plurality of histories of the same type of operation instructions, an average value of the execution time lengths of the operation instructions can be calculated, wherein the average value of the execution time lengths is obtained by adding the execution time lengths of all the operation instructions of the same type and dividing the average value by the number of the operation instructions.

And taking the average value of the execution time length of the similar operation instructions as the predicted execution time length of the operation instructions. The predicted execution time length can be used as a reference to help operators or systems to schedule tasks and allocate resources. By taking the average value of the execution time length of the similar operation instructions as the predicted execution time length of the operation instructions, the historical data can be utilized to estimate the execution time length of the current operation instructions. Therefore, an operator can be helped to reasonably arrange the execution sequence of the operation tasks, and the time required by the operation is estimated in advance.

In step S503, by acquiring the search result of the operation record of the same type, it is found that the current operation instruction has no similar operation instruction in the history record, possibly because the operation instruction is a new or rare operation, which has not been recorded before. The operation experience record refers to execution duration information recorded by an operator or a system administrator according to past operation experiences. These records may contain execution times of the operation instructions, related precautions, optimization suggestions, etc.

Further, operation records similar to the current operation instruction are obtained from the operation experience records, and the experience values of the execution duration in the records are extracted, wherein the experience values of the execution duration are estimated execution duration of similar operations based on experience of an operator or a system administrator. And taking the experience value of the execution duration in the operation experience record as the predicted execution duration of the operation instruction. This predicted value can be used as a reference to assist an operator or system in task scheduling and resource allocation. By matching the operation experience record corresponding to the operation instruction, the experience of an operator or a system administrator can be obtained, so that the execution duration of the current operation instruction is predicted. This helps the operation task to be reasonably arranged, and the time required by the operation is estimated in advance, so that the task scheduling and the resource allocation are better performed.

According to the power grid operation plan scheduling method, the average value of the execution time length corresponding to the similar operation instructions and the execution time length experience value in the operation experience record are used as the predicted execution time length of the operation instructions, so that the uncertainty of the execution time of the operation instructions is reduced, and the execution reliability of the operation instructions is improved.

In one implementation manner of the present embodiment, as shown in fig. 6, step S105 of performing deferred risk assessment on a predetermined scheduling operation plan, generating corresponding deferred assessment data, and generating corresponding deferred dynamic update information according to the deferred assessment data includes the following steps:

s601, if delay evaluation data meet preset delay judgment standards, corresponding delay scheduling operations in a preset scheduling operation plan and delay times and delay durations corresponding to the delay scheduling operations are obtained;

s602, generating delay dynamic update information of an operation unit influenced by delay scheduling operation according to delay times and delay time.

In steps S601 to S602, the preset deferral determination criterion is a criterion that determines, according to a preset criterion, deferral evaluation data, and determines whether a deferral condition is reached. For example, the preset deferral determination criteria are related operations in which a deferral occurs for a scheduled operation and no suspension is required. The delay evaluation data refers to related data for evaluating a delay situation. For example, the deferred evaluation data includes operation plan data, that is, information such as scheduled execution time, execution sequence, etc. of each operation, where the operation plan data is the basis of deferred evaluation, and by comparing with the actual power grid operation situation, it can be determined whether deferred scheduling is required.

Further, according to the deferral evaluation data, it can be determined which operations need to be deferred for scheduling, and the operations need to be deferred are determined according to a preset deferral determination standard. The deferred scheduling operation refers to an operation which needs to be deferred scheduling, namely, an operation which cannot be performed according to a preset execution time, and for each operation which needs to be deferred scheduling, the number of deferred times and the deferred duration of each operation are recorded, wherein the number of deferred times indicates the number of times that the operation has been deferred, and the deferred duration indicates the total duration of the operation which has been deferred. And then, according to the obtained delay times and delay time length of the delay scheduling operation, corresponding delay dynamic update information can be generated, the delay times and total delay time length of the delay scheduling operation are recorded by the delay dynamic update information, and the delay dynamic update information can comprise delay conditions of operation units, delay reasons, influence of delay on other operations and the like.

For example, the first time delays 1/2 of the normal operation period and prompts all the affected operation units: since the A-phase operation is delayed, it is necessary to delay execution for about 20 minutes. The second time delays the normal operation time of 1/2 and prompts all the affected operation units: since the A-phase operation is delayed for the second time, it is required to be delayed for about 20 minutes in total. The third delay is to directly delay 1 operation time length and prompt all the affected operation units: and the delay time is undetermined because the operation of the A-variant is delayed for the third time. Wherein the scheduler may suspend operations that are unpredictable or interrupted, the suspended operations not participating in the operation scheduling.

According to the power grid operation plan scheduling method, according to the dynamic update information of the deferred scheduling operation, the corresponding work plan of the operation unit influenced by the deferred scheduling operation can be adjusted in time, so that the power grid operation plan scheduling method has flexibility and adaptability, and the executable performance and efficiency of scheduling the work plan are improved.

In one implementation manner of this embodiment, as shown in fig. 7, in step S106, in combination with the predetermined scheduling operation plan and deferred dynamic update information, the following steps are further included after the corresponding operation plan schedule is generated:

s701, if an emergency operation instruction exists in the operation plan scheduling, carrying out emergency evaluation on the emergency operation instruction, and generating a potential risk range corresponding to the emergency operation instruction;

s702, generating an emergency operation priority corresponding to an emergency operation instruction according to the potential risk range;

s703, inserting an emergency operation instruction into an operation sequence corresponding to the operation plan schedule according to the emergency operation priority.

In step S701, an emergency operation instruction: refers to an instruction or task that appears in the operation plan schedule that needs to be executed immediately. These operations are typically due to an emergency, emergency or other emergency situation. The emergency operation instruction is characterized by the need to take immediate action to ensure the safe and smooth progress of the project or task. The emergency operation instructions may further be evaluated to determine their urgency and priority. The purpose of the urgency assessment is to allocate appropriate resources and priorities to the emergency operation instructions for timely action based on the urgency of the operation and the impact that may be exerted.

Second, the risk that emergency operation instructions may create is assessed and defined. The potential risk range refers to a range of adverse consequences or potential problems that may occur when an emergency operation instruction is executed. By evaluating the range of potential risks, corresponding measures can be taken to mitigate or avoid the potential risks.

In steps S702 to S703, the emergency operation priority is to prioritize the emergency operation instructions according to the evaluation result of the above-mentioned risk potential range. Where a higher risk potential range corresponds to a higher priority for emergency operation, priority handling is required to reduce the risk potential and adverse consequences.

Second, the operation plan schedule may be arranged according to a predetermined execution time and order. These emergency operation instructions are inserted into the appropriate position in the operation sequence according to their emergency operation priority to ensure that they can be executed in time. The manner of inserting the emergency operation instructions may be to find appropriate locations in the operation plan schedule for inserting the instructions based on the emergency operation priorities of the emergency operation instructions. If the priority of the emergency operation instruction is high, it may be inserted in front of the planned operation to ensure that it is handled in a timely manner. If the priority of the emergency operation instruction is low, it may be inserted behind the planned operation to maintain the relative stability of the operation plan.
