[0056] The embodiments of the present invention provide a method, system, device and storage medium for controlling pre-arranged power outages in a power grid, which are used to solve the technical problems of low efficiency and high error rate of existing power outage plan control methods.

[0057] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0058] The present invention provides a method for controlling pre - arranged power outages in the power grid.

[0059] Please refer to Figure 1 , Figure 1 which shows a flowchart of a method for controlling pre - arranged power outages in the power grid provided by an embodiment of the present invention.

[0060] A method for controlling pre - arranged power outages in the power grid provided by an embodiment of the present invention includes steps S1 - S4.

[0061] Step S1, obtain all power outage plans for the next time period.

[0062] Among them, it can be connected to an intelligent terminal with permission, so as to receive all power outage plans for the next time period from the intelligent terminal. A corresponding human - machine interaction interface can also be provided for inputting all power outage plans for the next time period.

[0063] This time period can be one month or one quarter. For example, when one month is taken as a time period, all power outage plans for the next time period are all power outage monthly plans for the next month. If one quarter is taken as a time period, all power outage plans for the next time period are all power outage quarterly plans for the next quarter.

[0064] Step S2, score all the power outage plans according to a preset reliability contribution degree scoring rule, sort each of the power outage plans in descending order of the score value, and obtain a corresponding set of power outage plans.

[0065] In an implementable manner, the scoring of all the power outage plans according to a preset reliability contribution degree scoring rule includes:

[0066] The preset reliability contribution degree scoring rule is set as follows:

[0067] The power outage plan access categories are sequentially set as the first category, the second category, the third category, and the fourth category in descending order of reliability contribution degree. The first category is the power outage plan related to grid safety, equipment safety, or personal safety. The second category is the power outage plan related to power supply reliability and improving low voltage. The third category is the power outage plan related to user service expansion, supporting the optimization of the business environment, periodic maintenance, or preventive test and regular inspection work. The fourth category is the power outage plan related to other aspects that do not reduce the power outage time and do not improve the power supply reliability. Corresponding sub - categories are set for the first category, the second category, and the third category in turn, a corresponding keyword list is established for each sub - category, and each keyword list corresponds to a score value;

[0068] Extract the keywords of the power outage plan, match the keywords of the power outage plan with each keyword list, obtain the corresponding scoring values of all the matching keyword lists, take the maximum value of the scoring values in each major category as the score of that major category, and sum up the scores of each major category as the score of the power outage plan.

[0069] Among them, when matching the keywords of the power outage plan with each keyword list, if the keyword of the power outage plan matches one keyword in the keyword list, it means that the keyword of the power outage plan matches that keyword list, and then obtain the corresponding scoring value. Furthermore, divide each scoring value into the first major category, the second major category and the third major category, and take the maximum value of the scoring values in each major category as the score of that major category.

[0070] In one implementation, each power outage plan is set with tag information including keywords. All the keywords in the tag information can be used as the extracted keywords.

[0071] In another implementation, corresponding keyword extraction rules can be set according to the actual situation, and then keywords are extracted according to the keyword extraction rules.

[0072] In the above embodiments, the reliability contribution degree refers to the contribution of each power outage plan to the power supply reliability. After matching the keywords of the power outage plan with each keyword list, if there is no matching keyword, it means that the power outage plan belongs to the fourth major category, and set the scoring value of this fourth major category to 0 points. Among them, the specific keyword matching algorithm can adopt existing algorithms, and the embodiments of the present invention are not limited thereto.

[0073] Specifically when executing, in one implementation, the sub-categories and the scoring values of the corresponding keyword lists can be set for each major category in the following manner:

[0074] (1) Set the sub-categories and the scoring values of the corresponding keyword lists for the first major category:

[0075] Grid safety (50 points);

[0076] Equipment safety (50 points);

[0077] Personal safety (50 points);

[0078] (2) Set the sub-categories and the scoring values of the corresponding keyword lists for the second major category:

[0079] Increase power supply: New substation (50 points);

[0080] Increase power supply: New line (45 points);

[0081] New connection: New inter-station connection (30 points);

[0082] New connection: Create a non-same mother connection (25 points);

[0083] New connection: Create a connection (23 points);

[0084] Automation: Replace the connection point with an automatic switch (18 points);

[0085] Automation: Add / Replace an automatic switch (with a connection in the back section) (15 points),;

[0086] Automation: Add / Replace an automatic switch (without a connection in the back section) (12 points);

[0087] Automation: Adjust the distribution points of the automatic switch (10 points);

[0088] Reduce faults: Improve lightning protection across the line / Upgrade insulation transformation (18 points);

[0089] Reduce faults: Improve lightning protection / Upgrade insulation transformation for a certain switch section (10 points);

[0090] Solve heavy overload: Solve the heavy overload of the line (10 points);

[0091] Solve heavy overload: Solve the heavy overload of the substation area (10 points);

[0092] Solve low voltage: Solve the low voltage of the line (10 points);

[0093] Solve low voltage: Solve the low voltage of the substation area (10 points);

[0094] (3) Set the subcategories and the scoring values of the corresponding keyword lists for the third major category:

[0095] Periodic maintenance (10 points);

[0096] Pre-test and regular inspection (10 points);

[0097] User project (10 points);

[0098] Business expansion project (10 points);

[0099] Support the optimization of the business environment (10 points).

[0100] Among them, when setting the keyword list for each subcategory, it can be set according to the actual situation, and the embodiments of the present invention are not limited thereto.

[0101] The scoring operation of the embodiments of the present invention is simple and convenient. The power outage plans are scored according to the reliability contribution degree, which can ensure that the power outage plans with a large reliability contribution degree are arranged preferentially, thereby improving the power supply reliability.

[0102] Step S3: Traverse each power outage plan in the power outage plan set and determine one by one whether it meets the preset power outage indicators;

[0103] Step S4: Output the power outage plan set that meets the preset power outage indicators.

[0104] In an implementable manner, the preset power outage indicators include medium-voltage time-of-use indicators, low-voltage time-of-use indicators, and actual power transfer rate indicators. Meeting the medium-voltage time-of-use indicator means that the current total medium-voltage time-of-use does not exceed the medium-voltage time-of-use threshold. Meeting the low-voltage time-of-use indicator means that the current total low-voltage time-of-use does not exceed the low-voltage time-of-use threshold. Meeting the actual power transfer rate indicator means that the current actual power transfer rate is not lower than the power transfer rate threshold;

If it meets, place the current power outage plan into the first set and update the values of Sm, Sn, Sh1, and Sh2 (that is, execute Sn = Sn + 1, Sm = Sm + 1, Sh1 = Sh1 + So1, Sh2 = Sh2 + So1). If it does not meet, place the current power outage plan into the second set and execute step S02; if not, execute step S02;

[0110] S02. Calculate the current total medium-voltage time-of-use customers based on the current values of Sh1 and So1, and calculate the current total low-voltage time-of-use customers based on the current values of Sh2 and So2. If the calculation results meet the medium-voltage time-of-use customer index and the low-voltage time-of-use customer index, place the current power outage plan into the first set and update the values of Sm, Sh1, and Sh2 (i.e., execute Sm = Sm + 1, Sh1 = Sh1 + So1, Sh2 = Sh2 + So1); otherwise, execute step S03;

[0111] S03. Determine whether the second set is empty; if so, execute step S04; if not, traverse the power outage plans in the second set according to the judgment operation. The judgment operation includes: if the current power outage plan meets the actual power transfer rate index, place it into the first set and update Sm, Sn, Sh1, and Sh2, and remove the current power outage plan from the second set; if the current power outage plan does not meet the actual power transfer rate index, execute step S04;

[0112] S04. Determine whether the next power outage plan meets the preset power outage index until all power outage plans have been judged;

[0113] S05. Mark the first set as the power outage plan set that meets the preset power outage index, and mark the second set as the power outage plan set that does not meet the preset power outage index.

[0114] In one implementation, calculating the current actual power transfer rate based on the current values of Sm and Sn includes:

[0115] Calculate the current actual power transfer rate according to (Sm - Sn) / (Sm + 1)*100%.

[0116] In one implementation, calculating the current total low-voltage time-of-use customers based on the current values of Sh2 and So2 includes:

[0117] Take the sum of the current values of Sh2 and So2 as the current total low-voltage time-of-use customers.

[0118] Furthermore, in order to ensure the effectiveness of pre-arranged power outage control, the threshold data in the index can be fine-tuned and updated according to the specific operation conditions to ensure the accuracy of the reliability contribution model and improve the accuracy of pre-arranged power outage control.

[0119] In an achievable way, it further includes:
