[0079] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0080] Embodiment 1

[0081] Reference is made to Figure 1 , Figure 1A step flow diagram of an energy scheduling method based on provincial energy markers is provided for an embodiment of the present application. As shown in Figure 1 The embodiment of the present application proposes an energy scheduling method based on provincial energy markers, which includes steps 101 to 106, and each step is specifically as follows:

[0082] Step 101, based on historical energy allocation data, constructing power safety models of several time periods;

[0083] As an example of the embodiment, based on historical energy allocation data, obtaining the positions of energy net output provinces, the positions of energy net consumption provinces, the average power consumption values of each provincial node corresponding to different time periods, the minimum output power peak values and the maximum output power peak values; based on the average power consumption values of each provincial node corresponding to different time periods, the minimum output power peak values and the maximum output power peak values, constructing a standard power allocation model; based on the positions of energy net output provinces, the positions of energy net consumption provinces and the standard power allocation model, constructing power safety models of several time periods. In a specific implementable manner, based on the existing method, obtaining historical energy allocation data, and establishing basic power safety models of different time periods, the basic power safety models including: the positions of energy net output provinces, the positions of energy net consumption provinces and a standard power model, the standard power model including: the average power consumption values of each provincial node corresponding to different time periods, the minimum output power peak values and the maximum output power peak values. The above data are all stored in the corresponding models, and when the models are called, the corresponding data types are output according to the target data requirements.

[0084] Step 102, obtaining the power consumption peak value of the current time energy net consumption province and the power output peak value of the current time energy net output province, and based on the power safety models of the several time periods, obtaining a pre-power allocation model;

[0085] As an example of the embodiment, by substituting the power consumption peak value of the current time energy net consumption province and the power output peak value of the current time energy net output province into the standard power allocation model, a pre-power allocation model is obtained. In a specific implementable manner, referring to Figure 3 , Figure 3 A schematic diagram of a pre-power allocation model of an energy scheduling method based on provincial energy markers is provided for an embodiment of the present application. As shown in Figure 3As shown, the power consumption peak value corresponding to the current time energy net consumption province and the power output peak value corresponding to the current time energy net output province are substituted into the standard power allocation model to obtain a pre-power allocation model. The data set established by associating the energy net output province and the energy net consumption province in the pre-power allocation model is saved. In the pre-power allocation model, the positions of the energy net output province and the energy net consumption province are displayed by different colors, and are marked and displayed based on the energy type corresponding to the energy net output province in the historical data. The energy net output province and the energy net consumption province are also sorted according to the size of the power consumption peak value of the energy net output province or the size of the output power peak value of the energy net consumption province in the historical data, and the color of the energy net output province or the energy net consumption province is gradually deepened according to the small-to-large order. For example, the energy net output province or the energy net consumption province is distinguished and identified by different colors, and is distinguished according to the size of the power consumption or the size of the power supply according to the gradual color change of the energy type, and the energy type is determined, so that the change of the power output peak value is understood according to the natural resource law of different time periods, and the subsequent allocation scheme is more accurate. Thus, the pre-power allocation model is convenient for viewing, so that the power regulation scheme warning or simulation can be performed in advance, thereby ensuring power safety. More specifically, Figure 3 In the pre-power allocation model, the orange-red dashed line represents the energy demand core area in a certain regional province, the orange color represents the energy demand important area in a certain regional province, the purple color represents the energy demand secondary area in a certain regional province, the blue color represents the energy demand auxiliary area in a certain regional province, and the green color represents the energy demand attention area in a certain regional province. Different preset requirements are allocated to different types of marked nodes based on different regions to which the marked nodes belong, so that the energy dispatching meets different types of energy demand regions.

[0086] In step 103, based on the power consumption peak value corresponding to the current time energy net consumption province and the pre-power allocation model, the energy net consumption province meeting the first preset requirement is marked to obtain a first marked node.

[0087] As an example of the present embodiment, the first comparison result is obtained by comparing the power consumption peak value corresponding to the current time energy net consumption province with the average power consumption in the pre-power allocation model. The energy net consumption province meeting the first comparison result is marked as a safe node, wherein the first preset requirement is that the power consumption peak value is greater than the average power consumption. The energy net consumption province not meeting the first preset requirement is marked as a to-be-labeled node. The first marked node includes the safe node and the to-be-labeled node.

[0088] At step 104, based on the power consumption peak of the energy net consumption province area not satisfying the first preset requirement and the pre-power allocation model, the energy net output province area satisfying the second preset requirement is marked to obtain a second marked node;

[0089] As an example of the embodiment, based on the pre-power allocation model, the energy net output province area corresponding to the power consumption peak of the to-be-marked node is obtained, and the power output peak corresponding to the energy net output province area at the current time is obtained. The output power difference value is obtained by calculating the difference between the power output peak corresponding to the energy net output province area at the current time and the maximum output power peak in the pre-power allocation model. The second comparison result is obtained by comparing the output power difference value with the preset critical value. The energy net output province area satisfying the second preset requirement is marked as a rated node. The second preset requirement is that the output power difference value is greater than the preset critical value. The energy net output province area not satisfying the second preset requirement is marked as an output node. The second marked node includes the rated node and the output node. In a specific implementation, the energy net output province areas associated with the power consumption peak of the energy net consumption province area are sorted according to the size of the power consumption peak and obtained. The difference between the power output peak and the maximum output power peak in the energy net output province area is calculated, and the difference value is compared with the set critical value. When the difference value is greater than the critical value, the energy net output province area is marked as a rated node. When the difference value is less than the critical value, the energy net output province area is marked as an output node. The pre-power allocation model can also be modified based on the rated node and the output node. For example, by comparing the difference value corresponding to the energy net output province area with the set critical value, it can be determined whether the energy net output province area at the current time has an additional allocation quota to meet the additional supply of the energy net consumption province area with increased power demand, thereby ensuring the safe supply of provincial power allocation. By marking the energy net output province area as a rated node and an output node, the rated node and the output node provide basic data reference in the subsequent energy allocation process, so as to evaluate the energy security situation of the province and provide a basis for establishing a suitable energy allocation scheme. The calculation formula is as follows:

[0090] Output power difference value:

[0091]

[0092] Difference between power peaks:

[0093]

[0094] In the formula, is the output power difference value, represents the power output value of the energy net output province i, represents the maximum output power peak value of the energy net output province i in the power allocation model at time t, represents the phase difference value between the power peaks, represents the power output value of the energy net output province i, represents the maximum output power value of the energy net output province i.

[0095] In step 105, the energy net consumption provinces that meet the third preset requirement are marked by calculating the proportion of the second marked node in the energy net output province corresponding to the energy net consumption province, and the attention node is obtained.

[0096] As an example of the present embodiment, the rated node proportion value is obtained by calculating the proportion of the rated node in the energy net output province corresponding to the energy net consumption province. The calculation methods of the proportion of the second marked node and the rated node proportion are as follows:

[0097] The proportion of the second marked node is:

[0098]

[0099] The rated node proportion is:

[0100]

[0101] In the above formula, N is the total number of nodes in a certain region, D Tag2 is the total number of second marked nodes, represents that when the result of the formula is 1, otherwise 0. D att is the rated node proportion.

[0102] The energy net consumption province region whose rated node proportion value meets the third preset requirement is marked as a concerned node. When the rated node proportion value of the energy net consumption province region does not meet the third preset requirement, an added value between minimum output power peaks corresponding to the energy net output province region associated with the energy net consumption province region is calculated; a third comparison result is obtained by comparing the power consumption peak of the energy net consumption province region with the added value; the energy net consumption province region whose third comparison result meets a fourth preset requirement is marked as a concerned node; and the energy net consumption province region whose third comparison result does not meet the fourth preset requirement is marked as a safe node. In one implementation, the proportion of rated nodes in the energy net output province region associated with the energy net consumption province region is calculated. When the proportion is greater than 50% (equivalent to the third preset requirement), the energy net consumption province region is marked as a concerned node; when the proportion is less than 50%, the added value between minimum output power peaks corresponding to the energy net output province region associated with the energy net consumption province region is calculated, and the added value is compared with the actual power peak. When the added value is less than the actual power peak (equivalent to the fourth preset requirement), the energy net consumption province region is marked as a concerned node; and when the added value is greater than the actual power peak, the energy net consumption province region is marked as a safe node. For example, in the process of evaluating the provincial energy security situation, the proportion of rated nodes in the energy net output province region associated with the energy net consumption province region indicates that it has been determined whether the corresponding energy net output province region is in a sufficient supply state, and provides a basic reference for meeting the sudden demand of the energy net consumption province region. By marking the energy net consumption province region as a concerned node or a safe node, the provincial energy security situation is preliminarily evaluated, so as to determine the focus of provincial power allocation in the subsequent process, and to ensure the safe supply of provincial power allocation.

[0103] As another example of the present embodiment, based on historical energy allocation data, the historical power peak of the energy net consumption province region in a preset time interval is obtained; based on the historical power peak of the energy net consumption province region in the preset time interval, the power demand situation of the energy net consumption province region is determined; based on the power demand situation of the energy net consumption province region, the corresponding energy net consumption province region is marked to obtain a third marked node; and based on the third marked node, the outputable nodes are classified and marked as abnormal output nodes and normal output nodes. Specifically, when the power demand situation of the energy net consumption province region is power demand rising, the corresponding energy net consumption province region is marked as a rising node; and when the power demand situation of the energy net consumption province region is power demand falling, the corresponding energy net consumption province region is marked as a falling node, wherein the third marked node includes the rising node and the falling node. The number of rising nodes and falling nodes in the energy net consumption province region associated with the outputable nodes is obtained; and the calculation method is as follows:

[0104] Rising node calculation method:

[0105]

[0106] Down node calculation method:

[0107]

[0108] In the above formula, UP Tagi , DOWN Tagi respectively represent the number of rising nodes and the number of down nodes associated with the province i, and is the power demand of the province i associated with the province i at time t-1.

[0109] When the number of rising nodes in the energy net consumption province associated with the output node is greater than the number of down nodes, the output node is marked as an abnormal output node; when the number of rising nodes in the energy net consumption province associated with the output node is less than the number of down nodes, the output node is marked as a normal output node. A possible implementation is shown in Figure 3 The association between the energy net consumption province and the energy net output province can also be displayed in dashed lines. The association between the energy net output province and the energy net consumption province is associated with the number of rising nodes or down nodes to obtain in advance whether the power output of the energy net output province is normal, and is marked by an abnormal output node or a normal output node, which serves as a warning for subsequent power regulation process, so as to provide power safety by providing power regulation scheme early warning or simulation.

[0110] As another example of the present embodiment, based on historical energy allocation data, the historical output power peak value of the output node in the preset time interval is obtained; based on the historical output power peak value of the output node in the preset time interval, the power output of each output node is determined; based on the power output of each output node, the corresponding output node is marked to obtain a fourth marked node; based on the fourth marked node, the marking of the energy net consumption province is updated. Specifically, when the power output of the output node increases, the corresponding output node is marked as an expansion node; when the power output of the output node decreases, the corresponding output node is marked as a contraction node; wherein the fourth marked node includes: expansion node and contraction node. The total number of nodes of the energy net output province associated with the energy net consumption province marked as a rising node is obtained; the proportion of the expansion node in the total number of nodes is calculated to obtain an output proportion; when the output proportion is greater than a preset threshold, the marking of the energy net consumption province is updated to a normal node; when the output proportion is less than the preset threshold, the marking of the energy net consumption province is updated to a rising node.

[0111] A possible implementation is to obtain the total number of nodes of the energy net output province associated with the energy net consumption province marked as a rising node, and calculate the output proportion of the expansion node in the total number of nodes, and the calculation method is:

[0112] Expansion node ratio:

[0113]

[0114] In the above formula, Zoom Tag N represents the number ratio of the expansion node att The set of output nodes, a total of nodes; is the power output value corresponding to the energy net output province k in the t time, and is the power output value corresponding to the energy net output province k in the t-1 time.

[0115] When the output ratio is greater than 50%, the label of the energy net consumption province is updated to a normal node, and when the output ratio is less than 50%, the label of the energy net consumption province is updated to a rising node. When the power demand of the energy net consumption province changes, the energy net consumption province is marked as a falling node or an expansion node to provide early warning for subsequent power regulation process, reserve time for early establishment of power regulation scheme simulation, and display the association between the energy net consumption province and the energy net output province with a dashed line to provide a basic reference in the subsequent power allocation process, thereby providing basic data reference for power safety.

[0116] As another example of the present embodiment, in the pre-power allocation model, the expected energy supply relationship is established by the energy net consumption provinces corresponding to the energy net output provinces of the same energy net output provinces after the current time period in the historical data, and the expected energy supply relationship is marked in the data set; the positions of the different corresponding energy net output provinces and energy net consumption provinces in the expected energy supply relationship in different data sets are obtained, the transmission distance between the positions of the energy net output provinces and the energy net consumption provinces is calculated, and the transmission distance is compared with the set maximum transmission limit value; when the transmission distance is greater than the maximum transmission limit value, the corresponding expected energy supply relationship in the data set is marked with a distance warning mark, and when the transmission distance is less than the maximum transmission limit value, the corresponding expected energy supply relationship in the data set is marked with a distance normal mark; then the expected energy supply relationship corresponding to the distance warning mark or the distance normal mark in the data set is called, the transmission distance of the expected energy supply relationship marked with the distance normal mark is sorted in descending order, the smallest distance normal mark is obtained, when the energy net consumption province is a falling node, the expected energy supply relationship marked with the distance normal mark is marked with a controllable mark, and when the energy net consumption province is not a falling node, the expected energy supply relationship marked with the distance warning mark is changed to a priority processing mark. In the energy supply relationship, the increase of the transmission distance will increase the cost and the loss of power, so it is necessary to control the transmission distance, and by comparing the transmission distance in the expected energy supply relationship with the maximum transmission limit value, the transmission distance between different energy net consumption provinces and energy net output provinces is provided with a warning to reduce the transmission loss between the energy net consumption provinces and the energy net output provinces, so as to save the cost; at the same time, by the different types of energy net consumption provinces, the expected energy supply relationship is re-marked, so as to facilitate subsequent control, so as to improve the timeliness of the allocation scheme.

[0117] As another example of the embodiment, the positions of the energy net output provinces and the positions of the energy net consumption provinces in the pre-power allocation model are displayed by different colors. When the positions of the energy net output provinces and the positions of the energy net consumption provinces in the pre-power allocation model are displayed by different colors, the actual power peak values of the energy net output provinces or the output power peak values of the energy net consumption provinces in the historical data are sorted according to the size, and the colors of the energy net output provinces or the energy net consumption provinces are gradually deepened according to the small-to-large order. When the positions of the energy net output provinces and the positions of the energy net consumption provinces in the pre-power allocation model are displayed by different colors, the energy types corresponding to the energy net output provinces in the historical data are displayed based on the marking. The specific explanation is that: the energy net output provinces or the energy net consumption provinces are distinguished and recognized by displaying different colors, the correlation between the energy net consumption provinces and the energy net output provinces is displayed by a dashed line, so as to facilitate the energy allocation according to the dashed line. The colors are gradually changed to facilitate the determination of the power consumption or power supply of the energy net output provinces or the energy net consumption provinces, so as to facilitate the early warning or simulation of the power control scheme, thereby ensuring the power safety. The energy types are determined to facilitate the understanding of the change of the power output peak value according to the natural resource law of different time periods, so that the subsequent allocation scheme is more accurate.

[0119] As an example of the embodiment, based on the security node, the rated node, the outputtable node and the concerned node, the provincial energy security situation is evaluated to obtain a scheduling security situation evaluation result; and based on the scheduling security situation evaluation result, the provincial energy is scheduled. A specific explanation is that, after the energy net consumption provinces and the energy net output provinces are marked, the global energy allocation is assisted in planning and scheduling security situation evaluation according to the overall marking, including but not limited to: the security node, the rated node, the outputtable node and the concerned node, to obtain an energy allocation strategy and a scheduling security situation evaluation result, and based on the energy allocation strategy and the scheduling security situation evaluation result, the provincial energy is scheduled.
