Description

Technical Field

[0001] The present invention belongs to the technical field of power systems, and in particular relates to a method and system for adjusting a power supply strategy based on a power grid map. Background Art

[0002] During the power supply process, changes in user load or the output of distributed energy systems often cause deviations in voltage nodes in distribution stations, making it difficult to meet the power reliability needs of power users.

[0003] Using a power grid map allows dispatchers to quickly identify abnormal voltage nodes, thereby quickly processing abnormal voltage nodes in distribution stations. Specifically, in the invention patent application CN202411541640.3 "A method and system for dynamically adjusting power supply strategy of power grid based on graph calculation", the current power supply strategy is adjusted according to the shortest power transmission path, and the power grid is controlled to execute the adjusted power supply strategy, thereby improving the overall performance and stability of the power grid. However, there are the following technical problems:

[0004] Due to the differences in the busyness of service call processing in the power grid diagram, there are certain differences in the efficiency of operators in identifying and processing abnormal voltage conditions in distribution substations using the power grid diagram. Therefore, how to use the busyness of service call processing in the power grid diagram to generate a power supply strategy for abnormal voltage node regulation using the energy storage system in the distribution substation and improve the real-time regulation response of the energy storage system has become a technical problem that needs to be solved urgently.

[0005] In response to the above technical problems, the present application specifically provides a method and system for adjusting a power supply strategy based on a power grid map. Summary of the invention

[0006] To achieve the purpose of the present invention, the present invention adopts the following technical solutions:

[0007] In a first aspect, the present application provides a method for adjusting a power supply strategy based on a power grid map, specifically comprising:

[0008] S1 determines that the remaining energy storage adjustment space of the energy storage device in the distribution station area cannot meet the requirements based on the deviation of the monitoring node in the distribution station area on the reference date of the current date, and then proceeds to the next step;

[0009] S2 determines the call usage data of the monitoring nodes of a power grid diagram in the distribution substation area in different business types, and determines the associated business types of different monitoring nodes based on the call usage data;

[0010] S3 determines the screening frequent periods in the reference date based on the historical call data of service calls of different associated service types under the reference date of the current date, determines the data recognized as the screening frequent periods in different periods in the reference date, and combines the historical call data of service calls of the associated service types by operation and management personnel in different periods in the reference date. When the recognition and processing efficiency of the voltage deviation state in the distribution transformer area meets the requirements, proceed to the next step;

[0011] S4 determines the power supply processing strategy of the distribution transformer area based on the recognition result of the voltage deviation situation of the monitoring nodes in the distribution transformer area.

[0012] The beneficial effects of the present invention are as follows:

[0013] Based on the deviation situation of the monitoring nodes in the distribution transformer area in the reference date of the current date, it is determined whether the remaining energy storage adjustment space of the energy storage device in the distribution transformer area meets the requirements, thereby realizing the determination of the energy storage capacity demand of the energy storage device on the current date from the differences in the deviation situations of the monitoring nodes in the reference date of the current date, and also laying a foundation for generating a differentiated power supply processing strategy of the energy storage system in the distribution transformer area according to whether the remaining energy storage adjustment space meets the energy storage capacity demand difference.

[0014] Determining the power supply processing strategy of the distribution transformer area based on the recognition result of the voltage deviation situation of the monitoring nodes in the distribution transformer area not only avoids the technical problem of insufficient availability of the energy storage device caused by frequent use of the energy storage device, but also realizes the determination of the power supply processing strategy of the distribution transformer area from the perspective of the adjustment demand of the voltage deviation situation of the monitoring nodes by further combining the recognition result of the voltage deviation situation of the monitoring nodes, ensuring the reliability and stability of the voltage operation in the distribution transformer area.

[0015] A further technical solution is that the reference date is a historical date with deviations of weather data in different dimensions from the current date all within a preset deviation range.

[0016] A further technical solution is that the monitoring nodes are distribution network nodes with voltage monitoring devices in the distribution transformer area.

[0017] A further technical solution is that the deviation situation of the monitoring nodes includes the number of voltage deviations of the monitoring nodes in different reference dates.

[0018] A further technical solution is that determining that the remaining energy storage adjustment space of the energy storage device in the distribution transformer area cannot meet the requirements specifically includes:

[0019] Based on the deviation conditions of the monitoring nodes in different reference dates, determine the time periods with voltage deviation in different reference dates, and use them as voltage deviation time periods;

[0020] According to the adjustment data of the energy storage device in different voltage deviation time periods, determine the energy storage adjustment capacity when different voltage deviation time periods reach the voltage balance state;

[0021] Based on the energy storage adjustment capacity and the remaining energy storage adjustment space, determine the number of voltage deviation time periods with the energy storage adjustment capacity greater than the remaining energy storage adjustment space, and use it as the capacity deviation time period. According to the number of the capacity deviation time periods, determine whether the remaining energy storage adjustment space of the energy storage device in the distribution substation area meets the requirements.

[0022] A further technical solution is that when the number of the capacity deviation time periods is greater than the preset capacity deviation time period number threshold, it is determined that the remaining energy storage adjustment space of the energy storage device in the distribution substation area does not meet the requirements.

[0023] A further technical solution is that when the remaining energy storage adjustment space of the energy storage device in the distribution substation area meets the requirements, when there are monitoring nodes with voltage deviation, directly put the energy storage device in the distribution substation area into use.

[0024] A further technical solution is that the method for determining the associated service type of the monitoring node is:

[0025] Based on the call usage data of the monitoring node in different service types, determine the call usage times of the monitoring point in different service types and the call usage durations of different call usage times;

[0026] Use the call usage duration to determine the call usage times with the call usage duration greater than the preset usage duration threshold, and use it as the matching call usage times;

[0027] According to the matching call usage times of the service type, determine whether the service type belongs to the associated service type of the monitoring node.

[0028] A further technical solution is that when the matching call usage times of the service type is greater than the preset matching usage times threshold, it is determined that the service type belongs to the associated service type of the monitoring node.

[0029] A further technical solution is that the method for determining the power supply processing strategy of the distribution substation area is:

[0030] Based on the recognition result of the voltage deviation condition of the monitoring nodes in the distribution substation area, determine the voltage data of different monitoring nodes at different times within a preset time period;

[0031] Based on the voltage data of different monitoring nodes at different times, determine the deviation situation of the voltage data of the monitoring nodes at different times in different voltage deviation periods, determine the similar times in the voltage deviation periods based on the deviation situation, and use the voltage deviation periods in which the proportion of the number of similar times is greater than the preset proportion of the number of similar times as the reference deviation periods;

[0032] Based on the reference deviation periods at different times and the energy storage regulation capacity of different reference deviation periods, determine the energy storage regulation capacity at different times, and determine the power supply processing strategy of the distribution substation area according to the energy storage regulation capacity at different times.

[0033] A further technical solution is that the similar times are the times when the deviation amounts of the voltage data of the monitoring nodes in the voltage deviation period are all within the preset deviation amount range.

[0034] A further technical solution is that determining the power supply processing strategy of the distribution substation area according to the energy storage regulation capacity at different times specifically includes:

[0035] When the proportion of the number of times when the energy storage regulation capacity is not less than the preset regulation capacity threshold within the preset period is not greater than the preset proportion of the number of times threshold, it is determined that the power supply processing strategy of the distribution substation area is not to put into the energy storage device;

[0036] When the proportion of the number of times when the energy storage regulation capacity is not less than the preset regulation capacity threshold within the preset period is greater than the preset proportion of the number of times threshold, it is determined that the power supply processing strategy of the distribution substation area is to put into the energy storage device.

[0037] In a second aspect, the present invention provides a computer system, including: a memory and a processor connected by communication, and a computer program stored on the memory and capable of running on the processor, and when the processor runs the computer program, it executes the above-mentioned power supply strategy adjustment method based on a single map of the power grid.

[0048] Example 1

[0049] To solve the above problems, according to one aspect of the present invention, as Figure 1 shown, a power supply strategy adjustment method based on a single map of the power grid is provided, which specifically includes:

[0050] S1 When it is determined that the remaining energy storage adjustment space of the energy storage device in the distribution substation area does not meet the requirements based on the deviation situation of the monitoring nodes in the distribution substation area in the reference date of the current date, proceed to the next step;

[0051] S2 Determine the data used in the invocation of different service types by the monitoring nodes of the single map of the power grid in the distribution substation area, and determine the associated service types of different monitoring nodes based on the invocation usage data;

[0052] S3 determines the screening frequent periods in the reference date based on the historical call data of service calls of different associated service types under the reference date of the current date, determines the data in different periods that are identified as screening frequent periods in the reference date, and combines the historical call data of service calls of the associated service types by operation and management personnel in different periods in the reference date. When it is determined that the recognition and processing efficiency of the voltage deviation status in the distribution transformer area meets the requirements, proceed to the next step;

[0053] S4 determines the power supply processing strategy of the distribution transformer area based on the recognition result of the voltage deviation situation of the monitoring nodes in the distribution transformer area.

[0054] Furthermore, the reference date is a historical date whose deviation from the current date in weather data in different dimensions is within a preset deviation range.

[0055] Specifically, the reference date is a historical date whose deviation from the current date in weather data in different dimensions is within a preset deviation range.

[0056] It should be noted that the monitoring nodes are distribution network nodes with voltage monitoring devices in the distribution transformer area.

[0057] It can be understood that the deviation situation of the monitoring nodes includes the number of voltage deviations of the monitoring nodes in different reference dates.

[0058] Specifically, as Figure 2 shown, when it is determined that the remaining energy storage regulation space of the energy storage device in the distribution transformer area cannot meet the requirements, it specifically includes:

[0059] Based on the deviation situations of the monitoring nodes in different reference dates, determine the periods with voltage deviations in different reference dates and use them as voltage deviation periods;

[0060] According to the regulation data of the energy storage device in different voltage deviation periods, determine the energy storage regulation capacity when different voltage deviation periods reach the voltage balance state;

[0061] Based on the energy storage regulation capacity and the remaining energy storage regulation space, determine the number of voltage deviation periods in which the energy storage regulation capacity is greater than the remaining energy storage regulation space and use it as the capacity deviation period. According to the number of capacity deviation periods, determine whether the remaining energy storage regulation space of the energy storage device in the distribution transformer area meets the requirements.

[0062] Furthermore, when the number of capacity deviation periods is greater than the preset capacity deviation period number threshold, it is determined that the remaining energy storage regulation space of the energy storage device in the distribution transformer area does not meet the requirements.

[0063] It can be understood that when the remaining energy storage adjustment space of the energy storage device in the distribution substation area meets the requirements, when there is a monitoring node with voltage deviation, the energy storage device in the distribution substation area is directly put into use.

[0064] In another possible embodiment, determining that the remaining energy storage adjustment space of the energy storage device in the distribution substation area does not meet the requirements specifically includes:

[0065] Based on the deviation conditions of the monitoring nodes in different reference dates, determine the time periods with voltage deviation in different reference dates and use them as voltage deviation time periods. When the proportion of the number of reference dates with voltage deviation time periods is less than the preset proportion of the number of reference dates, it is determined that the remaining energy storage adjustment space of the energy storage device in the distribution substation area meets the requirements;

[0066] When the proportion of the number of reference dates with voltage deviation time periods is not less than the preset proportion of the number of reference dates:

[0067] According to the adjustment data of the energy storage device in different voltage deviation time periods, determine the energy storage adjustment capacity when different voltage deviation time periods reach the voltage balance state. Based on the energy storage adjustment capacity and the remaining energy storage adjustment space, when it is determined that there is no voltage deviation time period with an energy storage adjustment capacity greater than the remaining energy storage adjustment space, it is determined that the remaining energy storage adjustment space of the energy storage device in the distribution substation area meets the requirements;

[0068] Based on the energy storage adjustment capacity and the remaining energy storage adjustment space, when it is determined that there is a voltage deviation time period with an energy storage adjustment capacity greater than the remaining energy storage adjustment space:

[0069] Take the voltage deviation time period with an energy storage adjustment capacity greater than the remaining energy storage adjustment space as the capacity deviation time period. When the number of the capacity deviation time periods does not meet the requirements, it is determined that the remaining energy storage adjustment space of the energy storage device in the distribution substation area does not meet the requirements;

[0070] When the number of the capacity deviation time periods meets the requirements:

[0071] Obtain the proportion of the number of reference dates with capacity deviation time periods. When the proportion of the number of reference dates with capacity deviation time periods is greater than the preset value of the proportion of reference dates, it is determined that the remaining energy storage adjustment space of the energy storage device in the distribution substation area does not meet the requirements;

[0072] When the proportion of the number of reference dates with capacity deviation time periods is not greater than the preset value of the proportion of reference dates:

[0073] Determine the energy storage regulation deviation coefficient of different reference dates according to the number of capacity deviation periods in different reference dates and the deviation amount between the energy storage regulation capacity of different capacity deviation periods and the remaining energy storage regulation space. When there is a reference date for which the energy storage regulation deviation coefficient does not meet the requirements, it is determined that the remaining energy storage regulation space of the energy storage device in the distribution substation area does not meet the requirements;

[0074] When there is no reference date for which the energy storage regulation deviation coefficient does not meet the requirements:

[0075] Determine the capacity deviation value of the distribution substation area based on the energy storage regulation deviation coefficients of different reference dates, and use the capacity deviation value to determine whether the remaining energy storage regulation space of the energy storage device in the distribution substation area meets the requirements.

[0076] Furthermore, when the capacity deviation value is greater than the preset capacity deviation threshold, it is determined that the remaining energy storage regulation space of the energy storage device in the distribution substation area does not meet the requirements.

[0077] Specifically, the service types include marketing, dispatching, and operation and maintenance.

[0078] It should be noted that the called usage data includes the number of call usages of the monitoring point under different service types and the call usage duration of different call usages.

[0079] Specifically, as Figure 3 shown, the method for determining the associated service types of the monitoring node is:

[0080] Based on the called usage data of the monitoring node under different service types, determine the number of call usages of the monitoring point under different service types and the call usage duration of different call usages;

[0081] Use the call usage duration to determine the number of call usages with a call usage duration greater than the preset usage duration threshold, and use it as the matching call usage number;

[0082] Determine whether the service type belongs to the associated service type of the monitoring node according to the matching call usage number of the service type.

[0083] Furthermore, when the matching call usage number of the service type is greater than the preset matching usage number threshold, it is determined that the service type belongs to the associated service type of the monitoring node.

[0084] Specifically, the dimensions of the weather data include rainfall, temperature, humidity, and wind speed.

[0085] It should be noted that the call requirements include call requirements when the operating state of the power grid changes and call requirements when the power grid fails.

[0086] It can be understood that the historical call data includes the historical call times of service calls under different associated service types and the corresponding times of different historical call times.

[0087] It should be noted that the method for determining the frequently-occurring period in the reference date is as follows:

[0088] Based on the historical call data of service calls under different associated service types in the period under the reference date, determine the historical call times of service calls under different associated service types;

[0089] According to the historical call times of service calls under different associated service types, determine the total historical call times in the period;

[0090] Based on the total historical call times, determine whether the period is a frequently-occurring period to be screened.

[0091] It can be understood that when the total historical call times in the period are greater than the preset call times threshold, it is determined that the period is a frequently-occurring period to be screened.

[0092] In another possible embodiment, the method for determining the frequently-occurring period in the reference date is as follows:

[0093] Based on the historical call data of service calls under different associated service types in the period under the reference date, determine the historical call times of service calls under different associated service types, and according to the historical call times of service calls under different associated service types, determine the total historical call times in the period;

[0094] When the total historical call times in the period are greater than the preset call times threshold, it is determined that the period belongs to the frequently-occurring period to be screened in the reference date;

[0095] When the total historical call times in the period are not greater than the preset call times threshold:

[0096] When the total historical call times in the period are within the preset call times range, it is determined that the period does not belong to the frequently-occurring period to be screened in the reference date;

[0097] When the total historical call times in the period are not within the preset call times range:

[0098] Based on the period and the unit time length, divide the period into multiple unit periods. When it is determined that there is no frequently-called unit period in the unit periods based on the historical call times of service calls in different unit periods, it is determined that the period does not belong to the frequently-occurring period to be screened in the reference date;

[0099] When there are frequently called unit time periods in the unit time period:

[0100] Obtain the number of frequently called unit time periods in the time period. When the number of frequently called unit time periods in the time period is greater than the preset number of unit time periods, it is determined that the time period belongs to the frequently screened time period in the reference date;

[0101] When the number of frequently called unit time periods in the time period is not greater than the preset number of unit time periods:

[0102] According to the historical call times of service calls in different unit time periods and the time intervals between different historical call times, determine the call busy coefficients of different unit time periods. When the average value of the call frequent coefficients of different unit time periods does not meet the requirements, it is determined that the time period belongs to the frequently screened time period in the reference date;

[0103] When the average value of the call frequent coefficients of different unit time periods meets the requirements:

[0104] Determine the comprehensive call frequent coefficient of the time period according to the product of the average value of the call frequent coefficients of different unit time periods and the proportion of the number of unit time periods with call frequent coefficients greater than the preset frequent coefficient threshold, and use the comprehensive call frequent coefficient to determine whether the time period is a frequently screened time period.

[0105] It should be noted that the value range of the comprehensive call frequent coefficient is between 0 and 1. When the comprehensive call frequent coefficient of the time period is greater than the preset frequent coefficient threshold, it is determined that the time period is a frequently screened time period.

[0106] Furthermore, the data recognized as the frequently screened time period includes the number of reference dates in which the time period is recognized as the frequently screened time period in different reference dates.

[0107] It can be understood that determining that the recognition processing efficiency of the voltage deviation state in the distribution transformer area meets the requirements specifically includes:

[0108] Based on the data in which the time period is recognized as the frequently screened time period in the reference date, determine the number of reference dates in which the time period is recognized as the frequently screened time period in the reference date, and determine the frequently screened service time period in the time period according to the number of reference dates recognized as the frequently screened time period;

[0109] Through the historical call data of service calls by operation and management personnel under different associated business types in different reference dates for the frequently screened service time period, determine the average value of the historical call times of the frequently screened service time period in each reference date;

[0110] By screening frequent time periods through different services and summing the average values of the historical call counts in each reference date, it is determined whether the recognition processing efficiency of the voltage deviation state in the distribution transformer area meets the requirements.

[0111] Furthermore, the service for screening frequent time periods is a time period in which the number of reference dates identified as frequent screening time periods is within a preset date number range.

[0112] It should be noted that by screening frequent time periods through different services and summing the average values of the historical call counts in each reference date, determining whether the recognition processing efficiency of the voltage deviation state in the distribution transformer area meets the requirements specifically includes:

[0113] When the sum of the average values of the historical call counts in each reference date when different services screen frequent time periods is greater than a preset number threshold, it is determined that the recognition processing efficiency of the voltage deviation state in the distribution transformer area cannot meet the requirements.

[0114] Specifically, when the recognition processing efficiency of the voltage deviation state in the distribution transformer area cannot meet the requirements, when there is a monitoring node with a voltage deviation, the energy storage device of the distribution transformer area is directly put into use.

[0115] In another possible embodiment, determining that the recognition processing efficiency of the voltage deviation state in the distribution transformer area meets the requirements specifically includes:

[0116] Based on the historical call data of the service calls of the operation management personnel in different reference dates, the total number of historical service calls of the operation management personnel in different reference dates is determined. When the average value of the total number of historical service calls of the operation management personnel in different reference dates does not meet the requirements, it is determined that the recognition processing efficiency of the voltage deviation state in the distribution transformer area cannot meet the requirements;

[0117] When the average value of the total number of historical service calls of the operation management personnel in different reference dates meets the requirements:

[0118] The reference dates with the total number of historical service calls of the operation management personnel greater than the call count limit value are used as frequent call dates. When the proportion of the number of frequent call dates in the reference dates is greater than the preset date number proportion, it is determined that the recognition processing efficiency of the voltage deviation state in the distribution transformer area cannot meet the requirements;

[0119] When the proportion of the number of frequent call dates in the reference dates is not greater than the preset date number proportion:

[0120] Based on the data identified as the screening frequent period in the reference date for the said time period, when it is determined that there is no time period not identified as the screening frequent period, it is determined that the identification processing efficiency of the voltage deviation state in the distribution substation area cannot meet the requirements;

[0121] When there is a time period not identified as the screening frequent period:

[0122] Determine the number of reference dates in which the said time period is identified as the screening frequent period in the reference date, and based on the number of reference dates identified as the screening frequent period, determine the service screening frequent period in the said time period. When the number of service screening frequent periods does not meet the requirements, it is determined that the identification processing efficiency of the voltage deviation state in the distribution substation area cannot meet the requirements;

[0123] When the number of service screening frequent periods meets the requirements:

[0124] Through the historical call data of service calls made by operation and management personnel under different associated business types in different reference dates for the service screening frequent period, determine the average value of the historical call times of the service screening frequent period in each reference date;

[0125] Determine whether the identification processing efficiency of the voltage deviation state in the distribution substation area meets the requirements through the sum of the average values of the historical call times of different service screening frequent periods in each reference date.

[0126] Further, as Figure 4 shown, the method for determining the power supply processing strategy of the distribution substation area is:

[0127] Based on the identification result of the voltage deviation situation of the monitoring nodes in the distribution substation area, determine the voltage data of different monitoring nodes at different times within a preset time period;

[0128] According to the voltage data of different monitoring nodes at different times, determine the deviation situation of the voltage data of the monitoring nodes at different times in different voltage deviation time periods. Based on the deviation situation, determine the similar times in the voltage deviation time periods, and use the voltage deviation time periods in which the proportion of the number of similar times is greater than the preset proportion of the number of similar times as the reference deviation time periods;

[0129] Based on the reference deviation time periods at different times and the energy storage regulation capacity of different reference deviation time periods, determine the energy storage regulation capacity at different times, and determine the power supply processing strategy of the distribution substation area according to the energy storage regulation capacity at different times.

[0130] Further, the similar times are the times when the deviation amounts of the voltage data of the monitoring nodes in the voltage deviation time period are all within the preset deviation amount range.

[0131] It should be noted that the power supply processing strategy of the distribution substation area is determined according to the energy storage regulation capacity at different times, which specifically includes:

[0132] When the proportion of the number of moments when the energy storage regulation capacity is not less than the preset regulation capacity threshold within the preset time period does not exceed the preset proportion threshold of the number of moments, it is determined that the power supply processing strategy of the distribution substation area is not to put into the energy storage device;

[0133] When the proportion of the number of moments when the energy storage regulation capacity is not less than the preset regulation capacity threshold within the preset time period is greater than the preset proportion threshold of the number of moments, it is determined that the power supply processing strategy of the distribution substation area is to put into the energy storage device.
