It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Example one
Fig. 1 is a flowchart of a method for detecting abnormal power generation according to an embodiment of the present invention, which is applicable to detecting whether photovoltaic power generation of a user is abnormal, and the method may be performed by a device for detecting abnormal power generation, which may be implemented in a form of hardware and/or software, and the device for detecting abnormal power generation may be configured in an electronic device with data processing capability. As shown in fig. 1, the method includes:
and S110, acquiring the generated power of the target user in at least two periods.
Wherein the target user may be a user of an installed photovoltaic power generation device, the target user includes but is not limited to: personal users, home users, business users, and the like. In the embodiment of the application, the photovoltaic power generation power of the target user is greatly influenced by illumination, for example, in one day, the power generation power of the target user is high in a time period with sufficient illumination, and the power generation power of the target user is low in a time period with insufficient illumination, so that the power generation power of the target user in at least two periods needs to be acquired, and partial data is screened out in subsequent steps to avoid the influence of the illumination on the power generation power.
Specifically, the generated power of the target user in at least two cycles may be obtained through the metering system, the obtaining time and the obtaining number of the generated power in each cycle may be preset, and the duration of each cycle is 24 hours as an example: the collection number of the generated power in each period can be 96, the generated power is collected every 15 minutes, and the time for collecting the generated power in each period is the same.
For example, the duration of one cycle may be one day, and the duration of one cycle may also be a fixed time period in one day, and the duration of each cycle is not limited in this embodiment of the application.
And S120, determining the generated power of the target user at the same time in two adjacent periods according to the generated power of the target user in at least two periods.
In the embodiment of the application, because the generated power can be influenced by meteorological changes, the generated power in different periods has certain difference, so that the period of generated power fluctuation caused by the meteorological changes is excluded from the generated power data of each period, and the influence of the meteorological changes on the generated power is reduced.
Furthermore, after the influence of meteorological change on the generated power is eliminated, the illumination conditions are approximate at the same time of two adjacent periods, so that the generated power of the target user at the same time of two adjacent periods is determined from each generated power, and the influence of the illumination difference on the generated power can be effectively avoided.
And S130, judging whether the generated energy of the target user is abnormal or not according to the generated power of the target user at the same time in two adjacent periods.
The abnormal generating capacity refers to abnormal power generation caused by the fact that a target user installs photovoltaic power generation equipment additionally. In the embodiment of the application, if the target user is additionally provided with the photovoltaic power generation device, the generated power of the target user may fluctuate greatly, that is, the generated power of the target user at the same time in two adjacent periods may have a large difference. If the target user is not additionally provided with the photovoltaic power generation equipment, the generated power of the target user is stable, namely the generated power values of the target user at the same time of two adjacent periods are closer.
The technical scheme of the embodiment of the application comprises the following steps: acquiring the generated power of a target user in at least two periods; determining the generated power of the target user at the same time of two adjacent periods according to the generated power of the target user in at least two periods; and judging whether the generated energy of the target user is abnormal or not according to the generated power of the target user at the same time of two adjacent periods. According to the technical scheme, the generated power of the target user at the same time in two adjacent periods is compared, so that the influence of meteorological change and illumination conditions on the generated power is avoided to a certain extent, and the effect of reducing the misjudgment rate of abnormal detection is achieved.
In this embodiment of the application, optionally, determining whether the generated energy of the target user is abnormal according to the generated power of the target user in two adjacent cycles at the same time includes: determining the difference value of the generated power of the target user at the same time in two adjacent periods according to the generated power of the target user at the same time in two adjacent periods; and judging whether the generated energy of the target user is abnormal or not according to the difference value of the generated power of the target user at the same time of two adjacent periods.
Specifically, in the generated power at the same time in two adjacent periods of the target user, the generated power at the time in the next period is subtracted from the generated power at the time in the previous period to obtain a difference value of the generated power at the same time in the two adjacent periods of the target user, and according to the difference value, the variation condition of the generated power at the same time in the two adjacent periods of the target user can be determined, so as to determine whether the generated energy of the target user is abnormal. In FIG. 2, C (n+1)j The generated power of the next period in the generated power of the same time of two adjacent periods of the target user, C nj Generated power for the previous cycle, D nj The difference value of the generated power of the target user at the same moment of two adjacent periods is shown.
In this embodiment of the application, optionally, determining whether the generated energy of the target user is abnormal according to the difference between the generated powers of the target user in two adjacent cycles at the same time includes: and if the difference value of the generated power of the target user at the target time of two adjacent periods is larger than a second threshold value, determining that the generated energy of the target user is abnormal.
The target time may be any one of the same time of two adjacent periods of the target user. The second threshold may be determined according to actual conditions, and the specific value of the second threshold is not limited in this embodiment.
Specifically, the second threshold may be predetermined according to historical data, and if the difference between the generated powers of the target users at the target time in two adjacent periods is greater than the second threshold, it is indicated that the generated power of the target user is suddenly and greatly increased, and it may be determined that the generated power of the target user is abnormal.
In this embodiment of the application, optionally, the second threshold is obtained according to the installed capacity and the abnormal coefficient.
The installed capacity refers to the rated capacity of the photovoltaic power generation equipment installed by the target user. The abnormal coefficient can be determined according to actual conditions, and the specific numerical value of the abnormal coefficient is not limited in the embodiment of the application. Specifically, the generated power of the target user is affected by the installed capacity and fluctuates in a certain range, so that the normal fluctuation range of the generated power can be determined according to the historical generated power of the target user at the same time in two adjacent periods, an abnormal coefficient capable of reflecting the abnormal fluctuation range is further obtained, and the installed capacity is multiplied by the abnormal coefficient to obtain the second threshold. Illustratively, the anomaly coefficient may be 9%.
Example two
Fig. 3 is a flowchart of a method for detecting abnormal power generation according to the second embodiment of the present application, where the second embodiment of the present application optimizes a process of determining power generation power of a target user at the same time in two adjacent periods based on the above embodiments.
As shown in fig. 3, the method of the embodiment of the present application specifically includes the following steps:
and S210, acquiring the generated power of the target user in at least two periods.
And S220, judging whether the generated power of the target period of the target user is qualified according to the maximum value of the generated power of the target period of the target user and the generated power before and after the acquisition time of the maximum value.
In the embodiment of the present application, the generated power may be affected by weather, for example, when the period is a cloudy day and the next period is a sunny day, the difference between the generated powers at the same time in the two periods may be large, which affects subsequent determination of abnormal power generation conditions of the target user.
Further, in the same period, the weather may have a plurality of cloudy and sunny changes, which may cause the generated power of the target user to fluctuate greatly, and affect the subsequent determination of the abnormal power generation condition of the target user.
Specifically, according to the maximum value of the generated power of the target period of the target user and the generated power before and after the acquisition time of the maximum value, the embodiment of the application determines that the weather condition is stable and the weather is a period of non-cloudy days, and further determines that the generated power of the period is qualified.
In this embodiment of the present application, optionally, if the maximum value of the generated power in the target period of the target user is greater than the first threshold, the generated data before the acquisition time of the maximum value satisfies the monotonically increasing condition, and the generated data after the acquisition time of the maximum value satisfies the monotonically decreasing condition, it is determined that the generated power in the target period of the target user is qualified.
The first threshold may be determined according to actual conditions, and the specific numerical value is not limited in the embodiment of the present application.
Specifically, the generated power of the target period of the target user is traversed, and the maximum value of the generated power is determined, wherein the maximum value is expressed by the following formula:
Ai.max＝max(Aij)＝Ait；
wherein A is i.max And A it Represents the maximum value of the generated power of the target user in the target period, A it The corner mark t of (A) represents the acquisition time corresponding to the maximum value ij J is the jth time, j =1, 2, 3, etc., for each generated power of the target user in the target period.
In the acquisition time of the maximum value and the generated power data before the acquisition time, the generated power at the next time is subtracted by the generated power at the previous time to obtain a difference B of the generated power at two adjacent times im1 ：
B im1 ＝A i(t-m) -A i(t-m-1) ；
Wherein A is i(t-m) Is the generated power at the moment of acquisition of the maximum value and at the latter moment of two adjacent moments before the moment of acquisition, A i(t-m-1) M =0, 1, 2, 3, etc. for the maximum value of the generated power at the acquisition time and the previous time of two adjacent times before the acquisition time.
Exemplarily, FIG. 4 is B im1 Schematic representation of (a).
In the acquisition time of the maximum value and the generated power data after the acquisition time, the generated power at the former time is subtracted by the generated power at the latter time to obtain a difference B of the generated power at two adjacent times im2 ：
B im2 ＝A i(t+m) -A i(t+m+1) ；
Wherein A is i(t+m) The maximum value and the generated power at the time immediately before the acquisition time, A i(t+m+1) M =0, 1, 2, 3, etc. that is the generated power at the acquisition time of the maximum value and at the latter time of the two adjacent times after the acquisition time.
Further, the fact that the generated power data before the acquisition time of the maximum value of the generated power of the target period of the target user satisfies the monotonically increasing condition may be expressed as:
B im1 ＞0。
the power generation data after the acquisition timing of the maximum value of the power generation power of the target period of the target user satisfies the monotonically decreasing condition may be expressed as:
B im2 ＞0。
in this embodiment of the application, optionally, the first threshold is obtained according to installed capacity and a weather coefficient.
The weather coefficient can be determined according to actual conditions, and the specific numerical value of the weather coefficient is not limited in the embodiment of the application. Specifically, the range of the generated power under the cloudy condition is determined according to the historical generated power of the target user, so that a weather coefficient capable of reflecting non-cloudy weather is obtained, and the installed capacity is multiplied by the weather coefficient to obtain a first threshold value. For example, the weather factor may be 50%.
Further, the maximum value of the generated power of the target period of the target user being greater than the first threshold value may be expressed as:
A i.max ＞P e ×50％；
wherein A is i.max Represents the maximum value of the generated power, P, of the target user in the target period e For installed capacity, 50% is the weather coefficient.
And S230, determining the generated power of the target user at the same time in two adjacent periods according to the generated power of the target user in at least two qualified periods.
S240, judging whether the generated energy of the target user is abnormal or not according to the generated power of the target user at the same time of two adjacent periods.
The technical scheme of the embodiment of the application comprises the following steps: acquiring the generated power of a target user in at least two periods; judging whether the generated power of the target period of the target user is qualified or not according to the maximum value of the generated power of the target period of the target user and the generated power before and after the acquisition time of the maximum value; determining the generated power of the target user at the same time of two adjacent periods according to the generated power of the target user in at least two qualified periods; and judging whether the generated energy of the target user is abnormal or not according to the generated power of the target user at the same time of two adjacent periods. According to the technical scheme, the qualified periods in all the periods are screened, the periods with variable weather or cloudy weather conditions are eliminated, and the misjudgment rate of abnormal detection is greatly reduced.
