Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In view of the problem of poor effect of the existing power load management method, embodiments of the present invention provide a power load management method and apparatus, where the technology may be applied to work flows such as energy efficiency management in which a power operation department manages and adjusts power loads in an area to make the power loads in the area tend to be stable, and the technology may be implemented by using related software or hardware, and is described below by using embodiments.
The first embodiment is as follows:
referring to fig. 1, a first power load management method is shown in a flowchart, which includes the steps of:
step S102, acquiring power utilization data of a current area; the power utilization data comprises power consumers, power utilization properties of the power consumers, power utilization time periods and power consumption corresponding to the power consumers and the power utilization time periods;
in actual implementation, the electricity utilization property of the power consumer can be obtained through the electricity utilization application submitted by the power consumer; through the smart meter of the power consumer, the power consumption time period of the power consumer and the power consumption amount corresponding to the power consumer and the power consumption time period can be obtained. The intelligent electric meter can send the power consumption of the corresponding power consumers in a timing mode, and the shorter the sending period is, the more accurately the acquired power consumption data of the plurality of power consumers can reflect the power consumption law of the current area.
Step S104, determining the electricity consumption valley time period and the electricity consumption peak time period of the current area according to the electricity consumption time period and the electricity consumption amount corresponding to the electricity consumption time period;
for example, a reasonable power consumption range of a current area in a fixed time period can be set according to historical power consumption data, and if the power consumption of a certain time period is in accordance with the power consumption range, the power consumption of a power consumer in the time period is normal, and management and adjustment are not needed; if the power consumption in a certain time period exceeds the power consumption range, the power consumption of the power consumers in the time period is over high or over low, and measures need to be taken to adjust the power consumption in order to avoid unreasonable utilization of power resources caused by large power load fluctuation.
Step S106, determining a power load adjustment object according to the power utilization property of the power consumer;
considering that a part of power consumers have high power supply requirements, in order to avoid large economic loss to the power consumers caused by randomly adjusting the power utilization plan, power load adjustment objects need to be screened according to the power utilization properties of the power consumers.
Generally, the electricity consumption property comprises residential life electricity, general industrial and commercial electricity, large industrial electricity and agricultural production electricity; in consideration of the rough division of the electricity utilization properties, in practical implementation, further screening can be performed according to the geographic location of the power consumer, the electricity utilization scale and the specific production industry under each electricity utilization property.
And step S108, adjusting the power utilization plans of the power utilization trough time period and the power utilization peak time period of the power load adjustment object until the fluctuation degree of the power utilization amount corresponding to different power utilization time periods in the current area accords with the preset fluctuation range.
For example, in the peak power consumption time period, the power demand is high, and the electric energy output of the power plant is difficult to satisfy the demands of all the power consumers, and in this case, it is necessary to add a power failure plan to the power consumption plan of the power load adjustment target in the peak power consumption time period, so as to reduce an accident or economic loss due to insufficient power supply when the peak power consumption time period comes.
For another example, in a case where the power demand is high during the power consumption valley period, the power generation amount of the power plant is redundant, and the power consumption plan to be adjusted for the power load during the power consumption valley period needs to be added with an energy storage plan to store redundant power in the energy storage facility of the power consumer in order to avoid waste of power.
According to the power load management method provided by the embodiment of the invention, the power utilization valley time period and the power utilization peak time period of the current area can be determined according to the obtained power utilization time period of the current area and the power consumption corresponding to the power utilization time period; according to the power utilization property of the power consumer, a power load adjustment object can be determined, and then the power utilization plan of the power load adjustment object in the power utilization valley time period and the power utilization peak time period is adjusted until the fluctuation degree of the power consumption corresponding to different power utilization time periods in the current area conforms to the preset fluctuation range; the method can adjust the power utilization plan according to the actual power utilization conditions of each power consumer in the region, and reduce the fluctuation degree of the power utilization valley and the power utilization peak in the region, so that the power load in the region tends to be stable, the electric energy can be better distributed and utilized, and the effect of the power load management mode is improved.
Example two
Referring to a flowchart of a second power load management method shown in fig. 2, the method is implemented on the basis of the power load management method provided in the first embodiment, and the method includes the following steps:
step S202, acquiring power utilization data of a current area; the power utilization data comprises power consumers, power utilization properties of the power consumers, power utilization time periods and power consumption corresponding to the power consumers and the power utilization time periods;
step S204, dividing the power consumption time period into a plurality of sub-time periods;
step S206, comparing the relation between the power consumption corresponding to each sub-time period and the preset power consumption range one by one; if the used amount is within the electricity utilization range, executing step S208; if the power consumption is higher than the maximum value in the power consumption range, executing step S210; if the used amount of electricity is less than the minimum value in the electricity range, S212 is performed;
step S208, determining the sub-time period as a normal electricity utilization time period; step S214 is executed;
step S210, determining the sub-time period as an electricity peak time period; step S214 is executed;
in step S212, the sub-period is determined to be the electricity consumption valley period.
Step S214, adjacent sub-time periods belonging to the same type are combined to generate the final electricity utilization valley time period and the final electricity utilization peak time period of the current area; wherein the types include a normal time period for electricity usage, a peak time period for electricity usage, and a valley time period for electricity usage.
In practical implementation, the divided sub-time periods are usually short, and therefore, after the type of each time period is determined, adjacent sub-time periods of the unified type need to be merged, and subsequent power utilization plan adjustment needs to be performed on the merged time periods.
Further, in order to improve the effectiveness of the power plan adjustment, after the type of each time period is determined, some shorter time periods may be different from the types of the preceding and following time periods, and therefore the shorter time periods are deleted, or the types are set to be the same as the types of the preceding and following time periods.
Step S216, acquiring the electricity utilization property of the power consumer in the current area;
step S218, setting the adjustment time and the adjustment priority of the power consumer according to the power utilization property, and generating a power load adjustment object corresponding to the adjustment time; wherein, the adjusting time comprises an electricity utilization valley time period and an electricity utilization peak time period.
For example, in the next year, a plurality of electricity valley periods and electricity peak periods may occur; specific multiple power load adjustment objects can be set for each power utilization valley time period or power utilization peak time period, and the multiple power load adjustment objects corresponding to each power utilization valley time period or power utilization peak time period are prioritized; when the electricity consumption trough time period or the electricity consumption peak time period comes, the power load adjustment object with high priority is adjusted first.
Step S220, adjusting the power consumption plan of the power consumption trough time period and the power consumption peak time period of the power load adjustment object until the fluctuation degree of the power consumption corresponding to the different power consumption time periods in the current area meets the preset fluctuation range.
According to the power load management method provided by the embodiment of the invention, the power consumption time periods can be divided into various types of sub-time periods by comparing the power consumption of the sub-time periods with the preset power consumption range; through the power consumption property of the power consumer, corresponding power load adjustment objects can be set for different types of time periods, and the method can clearly determine specific adjustment objects and adjustment modes when the power consumption valley time period or the power consumption peak time period comes, so that the power load in the region tends to be stable, electric energy can be better distributed and utilized, and the effect of a power load management mode is improved.
EXAMPLE III
Referring to a flowchart of a third power load management method shown in fig. 3, the method is implemented on the basis of the power load management method provided in the first embodiment, and the method includes the following steps:
step S302, acquiring power utilization data of a current area; the power utilization data comprises power consumers, power utilization properties of the power consumers, power utilization time periods and power consumption corresponding to the power consumers and the power utilization time periods;
step S304, determining the electricity consumption valley time period and the electricity consumption peak time period of the current area according to the electricity consumption time period and the electricity consumption amount corresponding to the electricity consumption time period;
step S306, determining a power load adjustment object according to the power utilization property of the power consumer;
step S308, acquiring the electricity consumption valley time period and the electricity consumption peak time period of the current area one by one; for each power utilization trough time period or power utilization peak time period, the following operations are performed:
step S310, acquiring a power load adjustment object corresponding to the current power utilization valley time period or the current power utilization peak time period;
step S312, sorting the power load adjusting objects according to the adjusting priority corresponding to the power load adjusting objects;
step S314, the power utilization plans of the power load adjustment objects are adjusted one by one according to the sorted sequence, and whether the power supply plan of the current power utilization trough time period or the power utilization peak time period conforms to the preset fluctuation range is calculated every time one power load adjustment object is adjusted, if not, the next power load adjustment object of the current power load adjustment object is continuously adjusted until the preset fluctuation range of the power supply plan load of the current power utilization trough time period or the power utilization peak time period.
For example, for one peak electricity consumption time period, the number of the power load adjustment objects corresponding to the peak electricity consumption time period is 4, and the four power load adjustment objects are respectively an object a, an object B, an object C and an object D, and the priority levels of the four power load adjustment objects are respectively the object a, the object B, the object C and the object D from high to low; when the electricity consumption peak time period comes, firstly, the power failure processing is carried out on the object A, after the processing, whether the electricity consumption in the current electricity consumption peak time period is reduced to a preset fluctuation range or not is calculated, and if not, the object B is processed until the electricity consumption in the current electricity consumption peak time period is reduced to the preset fluctuation range.
If the four adjusting objects are processed, the power consumption in the current power consumption peak time period is still not reduced to the preset fluctuation range, at the moment, the adjustment is stopped, and power is supplied according to the current power consumption plan.
According to the power load management method provided by the embodiment of the invention, power load adjustment objects corresponding to each power utilization trough time period and each power utilization peak time period are sequenced, and the power utilization plans of the power load adjustment objects are adjusted one by one according to the sequenced sequence until the current power utilization trough time period or the power supply plan load of the power utilization peak time period is within a preset fluctuation range; the method can be used for determining specific adjustment objects and adjustment modes when the electricity utilization valley time period or the electricity utilization peak time period comes, so that the power load in the region tends to be stable, the electric energy can be well distributed and utilized, and the effect of the power load management mode is improved.
