The power dispatching is an effective management means for ensuring safe and stable operation of the power grid, external reliable power supply and orderly execution of various power production works. The specific work content of the power dispatching is that according to data information fed back by various information acquisition devices or information provided by monitoring personnel, the actual operation parameters of the power grid, such as voltage, current, frequency, load and the like, are comprehensively considered, the development condition of various production works is comprehensively considered, the safe and economic operation state of the power grid is judged, and an operation instruction is issued through a telephone or an automatic system to command on-site operators or an automatic control system to adjust, such as adjusting the output of a generator, adjusting the load distribution, switching capacitors, reactors and the like, so that the continuous safe and stable operation of the power grid is ensured; for example, chinese patent document CN110138082B discloses a power distribution control method and a power distribution control system, where the power distribution control method and the power distribution control system calculate average basic power consumption and average improved power consumption, so that when the power distribution cannot meet the average basic power consumption of the area, the average basic power consumption of the area is preferentially met, and normal production of enterprises in the area is ensured.
In the related art, because the distribution amounts of the power grids distributed to all areas are different, in the power use process, the situations that some areas are excessive in distribution amount and some areas are insufficient in distribution amount exist, so that the electric quantity waste in the areas with excessive distribution amount and the electricity consumption requirement in the areas with insufficient distribution amount are easily caused, and the economic benefit is influenced.

step S100, obtaining the total electricity consumption of the ith sub-area and the electricity consumption of various electricity consumption types in each preset time interval of the past year, and predicting the predicted total electricity consumption of the ith sub-area and the predicted electricity consumption of various electricity consumption types in each preset time interval of the current year through a prediction model, wherein i=1, 2 to N;
step 200, changing the power consumption of the multiple power consumption types of the ith sub-area and the total power consumption of each of the N sub-areas in the next preset time interval according to the size relation between the predicted power consumption and the actual power consumption of each power consumption type of the ith sub-area in the preset time interval of the current year.
Further, after step S200, the method further includes:
step S210, when the predicted electricity consumption amount and the actual electricity consumption amount of any electricity consumption type of the ith sub-area in the preset time interval of the current year are equal, keeping the electricity consumption amount of the electricity consumption type of the ith sub-area unchanged in the next preset time interval; when the predicted electricity consumption of any electricity consumption type of the ith subarea in the preset time interval of the current year is smaller than the actual electricity consumption, the electricity consumption type receives the power supply of other electricity consumption types in the same area, and if the power consumption requirement is still not met, the electricity consumption type is marked as a power supply part to be supported; when the predicted electricity consumption of any electricity consumption type of the ith subarea in the preset time interval of the current year is larger than the actual electricity consumption, the electricity consumption type supplies power to other electricity consumption types in the same area, and if the electricity consumption type is still rich, the electricity consumption type is marked as a supporting power supply part;
in step S220, when the number of the power supply portions to be supported and the number of the power supply portions to be supported are both greater than zero, the matching mode is turned on to match the power supply portions to be supported and the power supply portions to be supported.
Further, the matching pattern includes:
step S221, when the number of the power supply parts to be supported is greater than or equal to the number of the power supply parts to be supported, the difference between the predicted power consumption and the actual power consumption in the power supply parts to be supported is the largest as a first supported object, and the difference between the actual power consumption and the predicted power consumption in the power supply parts to be supported is the closest as the first supported object;

step S223, the first support object supplies power to the first supported object;
step S224, after excluding the matched power supply portion to be supported, repeating step S221 or step S222 to step S223.
Further, matching is performed in the order of priority of the same pressure class being greater than the high pressure class and greater than the low pressure class.
Further, storing the surplus electric quantity of the rest matched supporting power supply part to a designated area; and the rest matched power supply parts to be supported receive power supply from the designated area.

As shown in fig. 1, fig. 1 is a schematic flow chart of an energy-saving power distribution control method according to an embodiment of the present invention, where the energy-saving power distribution control method is used for distributing power distribution in a set area, the set area includes N sub-areas, and the N sub-areas have multiple power utilization types; the energy-saving power distribution control method comprises the following steps:
step S100, obtaining the total electricity consumption of the ith sub-area and the electricity consumption of various electricity consumption types in each preset time interval of the past year, and predicting the predicted total electricity consumption of the ith sub-area and the predicted electricity consumption of various electricity consumption types in each preset time interval of the current year through a prediction model, wherein i=1, 2 to N;
taking an example that the set area comprises a province, the province comprises N cities, the subareas in the set area are cities in the province, and each city has four electricity utilization types of industrial electricity utilization, commercial electricity utilization, residential electricity utilization and public facility electricity utilization.
Assuming that N is equal to three, for convenience of description, the three cities are named as a city, B city and C city, respectively; taking city A as an example, the total electricity consumption of city A in each month of the past year and the four electricity consumption types of industrial electricity, commercial electricity, residential electricity and public facility electricity in the same time are obtained through an electricity measurement device, and the predicted total electricity consumption of city A in each month of the current year and the predicted electricity consumption of the four electricity consumption types of industrial electricity, commercial electricity, residential electricity and public facility electricity in the same time are predicted through a prediction module.
It is understood that the preset time interval may be set in units of one month, or may be set in units of one week, or may be set in units of a plurality of months or a plurality of weeks; the longer the preset time interval is, the smaller the fluctuation of the electric quantity data is, so that the adjustment of the electric quantity distribution is not needed frequently, the shorter the preset time interval is, the more accurate the data is, and therefore the fine adjustment can be realized, and the energy utilization efficiency is improved.
Step 200, changing the power consumption of the multiple power consumption types of the ith sub-area and the total power consumption of each of the N sub-areas in the next preset time interval according to the size relation between the predicted power consumption and the actual power consumption of each power consumption type of the ith sub-area in the preset time interval of the current year.
Specifically, according to the magnitude relation between the predicted electricity consumption and the actual electricity consumption of each electricity consumption type of the A city in each month of the current year, when the predicted electricity consumption and the actual electricity consumption of each electricity consumption type of the A city of the current year are unequal, linkage is generated between the power distribution amounts of multiple electricity consumption types of the A city, and when linkage is generated between the power distribution amounts of various electricity consumption types of the A city but the power consumption requirements are still not met, linkage is generated between the power distribution amounts of the A city, the B city and the C city, so that the electricity consumption can be distributed according to the actual requirements of the city, the power consumption requirements of different cities are met, and the energy utilization efficiency is improved.
It can be understood that the energy-saving power distribution control method provided by the invention is not only suitable for power distribution among cities, but also suitable for power distribution among different areas/counties in the same city or among different areas/counties in the same factory, and also suitable for power distribution among different factories in the same factory; for example, when power is distributed among different factories in the same factory, the electricity consumption types of the factories comprise factory electricity consumption, dormitory electricity consumption, equipment electricity consumption and the like, and then the electricity consumption can be distributed according to the electricity consumption conditions of different electricity consumption types in different time phases.
In some embodiments, after step S200, further comprising:
step S210, when the predicted electricity consumption amount and the actual electricity consumption amount of any electricity consumption type of the ith sub-area in the preset time interval of the current year are equal, keeping the electricity consumption amount of the electricity consumption type of the ith sub-area unchanged in the next preset time interval; when the predicted electricity consumption of any electricity consumption type of the ith subarea in the preset time interval of the current year is smaller than the actual electricity consumption, the electricity consumption type receives the power supply of other electricity consumption types in the same area, and if the power consumption requirement is still not met, the electricity consumption type is marked as a power supply part to be supported; when the predicted electricity consumption of any electricity consumption type of the ith subarea in the preset time interval of the current year is larger than the actual electricity consumption, the electricity consumption type supplies power to other electricity consumption types in the same area, and if the electricity consumption type is still rich, the electricity consumption type is marked as a supporting power supply part;
taking industrial electricity of the city a as an example, when the predicted electricity consumption and the actual electricity consumption of the industrial electricity of the city a in the month of the current year are equal, the electricity consumption of the industrial electricity of the city a in the month of the current year can just meet the electricity consumption requirement, the predicted electricity consumption of the industrial electricity of the city a in the month of the current year is accurate, and the accuracy of the predicted electricity consumption of the industrial electricity of the city a in the current year is high, so that the electricity consumption of the industrial electricity of the city a is not required to be adjusted, and the electricity consumption of the industrial electricity of the city a in the month of the february of the current year is set to be unchanged.
When the predicted power consumption of the current year's february a city is smaller than the actual power consumption, it is indicated that the power consumption of the current year's february a city cannot meet the power consumption requirement, that the current year's february a city power consumption is low, and that the current year's february a city power consumption is low, so that the current year's february a city power consumption needs to be regulated, that the current year's february a city power consumption receives power of other power consumption types of a city, and if the current year's february a city power consumption still does not meet the power consumption requirement, the current year's february a city power consumption is marked as a power supply waiting support part, and the current year's february B city and/or C city power supply support is waited.
When the predicted electricity consumption of the current year's month a city is larger than the actual electricity consumption, it is indicated that the electricity consumption of the current year's month a city is not only enough to meet the electricity consumption demand but also a surplus, that the predicted electricity consumption of the current year's month a city is higher as a whole, that the electricity consumption demands of other types of electricity consumption of the current year's city a city or the electricity consumption demands of the city B and city C are met, and therefore the electricity consumption of the city a industry needs to be adjusted, that the surplus electricity consumption of the current year's month a city is set to supply electricity to other electricity consumption types of the city a, and that the current year's month a city is marked as a support power supply part waiting for providing power supply support to the city B and/or city C if there is surplus.
It is to be understood that commercial power consumption, residential power consumption and public facility power consumption of the city A are all determined according to the same principle as the industrial power consumption of the city A; the industrial electricity, commercial electricity, resident electricity and public facility electricity of the city B and the city C are judged according to the principle same as that of the city A, so that all the parts to be supported and the supporting power supply part are determined, and the next operation is convenient.
In step S220, when the number of the power supply portions to be supported and the number of the power supply portions to be supported are both greater than zero, the matching mode is turned on to match the power supply portions to be supported and the power supply portions to be supported.
Specifically, when the number of the to-be-supported power supply parts and the number of the support power supply parts are both greater than zero, at least one pair of the to-be-supported power supply parts and the support power supply parts can be matched through the matching mode, and the support power supply parts can supply power to the to-be-supported power supply parts so as to meet the power consumption requirements of part or all of the to-be-supported power supply parts and avoid waste of redundant electric quantity of the support power supply parts.
In a further embodiment, the matching pattern comprises:
step S221, when the number of the power supply parts to be supported is greater than or equal to the number of the power supply parts to be supported, the difference between the predicted power consumption and the actual power consumption in the power supply parts to be supported is the largest as a first supported object, and the difference between the actual power consumption and the predicted power consumption in the power supply parts to be supported is the closest as the first supported object;
specifically, when the number of power supply portions to be supported is greater than or equal to the number of power supply portions to be supported, the description power supply is less than or equal to the determination, the number of power supply portions to be supported is assumed to be 3, the difference between the predicted power consumption and the actual power consumption in the power supply portions to be supported is assumed to be 4, 6, 8, the number of power supply portions to be supported is assumed to be 5, and the difference between the actual power consumption and the predicted power consumption in the power supply portions to be supported is assumed to be 2, 5, 8, 10, 11; if the power supply to be supported is taken as a reference, 11 in the power supply to be supported is matched with 8 in the power supply to be supported, at this time, the difference between the actual power consumption and the predicted power consumption in the power supply to be supported is 2, 3, 5, 8 and 10, then 10 in the power supply to be supported is matched with 6 in the power supply to be supported, at this time, the difference between the actual power consumption and the predicted power consumption in the power supply to be supported is 2, 3, 4 and 5, at this time, the number of the power supply to be supported is still 5, the total power consumption required by the power supply to be supported is 2+3+4+4+5=18, and the original 5 power supply to be supported is not sufficiently supplied.
If the power supply support part is used as a reference, 8 in the power supply support part is matched with 8 in the power supply support part, at the moment, the difference value of the actual power consumption and the predicted power consumption in the power supply support part is 2, 5, 10 and 11, 6 in the power supply support part is matched with 5 in the power supply support part, at the moment, the difference value of the predicted power consumption and the actual power consumption in the power supply support part is 1 and 4, the difference value of the actual power consumption and the predicted power consumption in the power supply support part is 2, 10 and 11, 4 in the power supply support part is matched with 2 in the power supply support part, at the moment, the difference value of the predicted power consumption and the actual power consumption in the power supply support part is 1 and 2, the difference between the actual power consumption and the predicted power consumption in the power supply part to be supported is 10 and 11, 2 in the power supply part to be supported is matched with 11 in the power supply part to be supported, the difference between the predicted power consumption and the actual power consumption in the power supply part to be supported is 1, the difference between the actual power consumption and the predicted power consumption in the power supply part to be supported is 9 and 10, 1 in the power supply part to be supported is matched with 9 in the power supply part to be supported, the difference between the actual power consumption and the predicted power consumption in the power supply part to be supported is 8 and 10, the number of the power supply parts to be supported is 2, the total power consumption required by the power supply part to be supported is 8+10=18, and 3 power supply parts to be supported in the original 5 power supply parts to be supported obtain sufficient power supply; in summary, by setting the support power supply unit as the first support target having the largest difference between the predicted power consumption and the actual power consumption in the support power supply unit, and setting the first support target having the closest difference between the actual power consumption and the predicted power consumption in the support power supply unit and the first support target, the number of the support power supply units can be reduced, the matching efficiency can be improved, and the number of power distribution to the support power supply units can be reduced.
Step S222, when the number of the power supply parts to be supported is smaller than the number of the power supply parts to be supported, the first supported object is the largest difference between the actual power consumption and the predicted power consumption in the power supply parts to be supported, and the first supported object is the closest difference between the predicted power consumption and the actual power consumption in the power supply parts to be supported;
specifically, when the number of power supply portions to be supported is smaller than the number of power supply portions to be supported, the description provides more power, the number of power supply portions to be supported is assumed to be 3, the difference between the actual power consumption and the predicted power consumption in the power supply portions to be supported is assumed to be 4, 6, 8, the number of power supply portions to be supported is assumed to be 5, and the difference between the predicted power consumption and the actual power consumption in the power supply portions to be supported is assumed to be 2, 5, 8, 10, 11; if the power supply to be supported is taken as a reference, 8 of the power supply to be supported is matched with 8 of the power supply to be supported, at the moment, the difference between the predicted power consumption and the actual power consumption in the power supply to be supported is 4 and 6, the difference between the predicted power consumption and the actual power consumption in the power supply to be supported is 2, 5, 10 and 11, then 6 of the power supply to be supported is matched with 10 of the power supply to be supported, at the moment, the difference between the predicted power consumption and the actual power consumption in the power supply to be supported is 4, the difference between the predicted power consumption and the actual power consumption in the power supply to be supported is 2, 4, 5 and 11, then 4 of the power supply to be supported is matched with 4 of the power supply to be supported, at the moment, the difference between the predicted power consumption and the actual power consumption in the power supply to be supported is 2, 5 and 11, at the moment, the number of the power supply to be supported is 3, the total power consumption that the power supply to be supplied by the power supply to be supported is 2+5+11=18, and 2 power supply parts of the original 5 power supply to be completely consumed.
If the power supply support portion is taken as a reference, 11 in the power supply support portion is matched with 8 in the power supply support portion, at the moment, the difference between the predicted power consumption and the actual power consumption in the power supply support portion is 2, 3, 5, 8 and 10, the difference between the actual power consumption and the predicted power consumption in the power supply support portion is 4 and 6, then 10 in the power supply support portion is matched with 6 in the power supply support portion, at the moment, the difference between the predicted power consumption and the actual power consumption in the power supply support portion is 2, 3, 4, 5 and 8, at the moment, the difference between the actual power consumption and the predicted power consumption in the power supply support portion is 4, 3, 4 and 5, at the moment, the number of the power supply support portions is 5, the total power consumption which can be provided by the power supply support portion is 2+3+4+4+5=18, and the original 5 power supply support portions are not used up; in summary, by taking the power supply to be supported as the first supported object with the largest difference between the actual power consumption and the predicted power consumption in the power supply to be supported, and taking the first supported object with the closest difference between the predicted power consumption and the actual power consumption in the power supply to be supported and the first supported object, the number of power supply to be supported is reduced, the matching efficiency is improved, and the number of power distribution times of the power supply to be supported is reduced.
Step S223, the first support object supplies power to the first supported object;
specifically, the first supporting object supplies power to the first supported object, so that linkage is generated among the power distribution amounts of the N sub-areas, electric quantity distribution can be performed according to actual demands of the sub-areas, power consumption demands of different sub-areas are met, and energy utilization efficiency is improved.
Step S224, after excluding the matched power supply portion to be supported, repeating step S221 or step S222 to step S223.

Specifically, since the power supply to be supported and the power supply to be supported may be from industrial power, commercial power, residential power and public facility power, and the industrial power, commercial power, residential power and public facility power are different in voltage, wherein the industrial power is generally greater than the commercial power, the commercial power is greater than the residential power, the residential power is greater than the public facility power, and the power is required to be boosted at low voltage to high voltage, and additional equipment and steps are required to be added, which is troublesome and consumes much energy, and the power is required to be reduced at high voltage to low voltage, which is troublesome but consumes little energy, in order to improve the energy utilization efficiency, the priority of the power supply to be supported for receiving the power supply to be supported is set to be the same voltage class and greater than the high voltage class and greater than the low voltage class.
In other embodiments, the method includes storing the surplus power of the remaining support power supply unit to a specified area; and the rest matched power supply parts to be supported receive power supply from the designated area.
Specifically, when the number of the power supply portions to be supported and the number of the power supply portions to be supported are unequal, there are always remaining power supply portions to be supported and remaining power supply portions to be supported, and in order to improve the energy utilization efficiency, the remaining power supply portions to be supported are set to store surplus power of the remaining power supply portions to be supported in the specified area, and the remaining power supply portions to be supported are set to receive power supplied from the specified area, so that power can be distributed according to the actual requirements of the sub-areas, and power consumption requirements of different sub-areas can be met.

specifically, when the predicted independent power supply quantity can meet the predicted power consumption quantity of any power type in the city A, the independent power supply is used for supplying power to the power type, and if a plurality of power supplies meet the predicted power consumption quantity, the power supply is supplied with the closest priority; when the predicted independent power supply quantity cannot meet the predicted power consumption quantity of any power consumption type in the city A, the independent power supply supplies power to the power consumption type with the minimum predicted power consumption quantity.
And step S130, the predicted total power consumption of the ith sub-area and the predicted power consumption of various power consumption types in the preset time interval of the current year are adjusted according to the independent power supply mode.
