Technical Field

[0001] The present application relates to the technical field of photovoltaic power generation, and in particular to a data synchronization method and device based on photovoltaic power generation. Background Art

[0002] As a common way to utilize solar energy resources, solar photovoltaic power generation systems have developed rapidly in recent years and are widely used in the field of clean energy supply. The solar energy conversion efficiency of photovoltaic power generation systems is the core factor in measuring the performance of a photovoltaic power station.

[0003] However, the various technical solutions related to the power quality of the power grid in the existing technology cannot effectively evaluate the specific power quality of the power supply grid monitored within a certain day in the future. This is because photovoltaic power generation is greatly affected by sunlight radiation. When the light changes drastically, the output power of the photovoltaic system will fluctuate greatly, and it has the characteristic of unstable power. At present, there is no power control system configured in photovoltaic power stations to complete power regulation of photovoltaic power sources, which cannot meet the demand for power regulation of photovoltaic power sources, causing trouble for the planning and operation scheduling of photovoltaic power generation. Summary of the invention

[0004] To achieve the above objectives, this application provides the following technical solutions:

[0005] According to a first aspect of the present invention, the present invention claims protection for a data synchronization method based on photovoltaic power generation, the data synchronization method comprising:

[0007] Clustering the photovoltaic power generation elements in the area of ​​interest is completed by configuring indicators, and a number of sub-photovoltaic power generation elements in the area of ​​interest are output;

[0008] For each photovoltaic power generation element to be synchronized, clustering is performed on each photovoltaic power generation element to be synchronized by using the configuration index, and a plurality of sub-photovoltaic power generation elements to be synchronized corresponding to each photovoltaic power generation element to be synchronized are output;

[0018] The correlation between the sub-photovoltaic power generation element in the area of ​​interest and the sub-photovoltaic power generation element to be synchronized under the consistency index is determined by the correlation between the normal power generation data and the abnormal power generation data, as well as the normal importance corresponding to the correlation between the normal power generation data and the abnormal importance corresponding to the correlation between the abnormal power generation data.

[0019] Furthermore, the following process is used to determine the correlation between the sub-photovoltaic power generation element in the concerned area and the sub-photovoltaic power generation element to be synchronized under the consistency index:

[0023] Furthermore, when the configuration index includes a non-environmental index, sub-photovoltaic power generation elements to be synchronized corresponding to the non-environmental index are clustered from the photovoltaic power generation elements to be synchronized, and the following process is used to determine the correlation between the sub-photovoltaic power generation elements in the area of ​​interest and the sub-photovoltaic power generation elements to be synchronized under the consistency index:

[0026] The correlation between the sub-photovoltaic power generation elements in the area of ​​interest and the sub-photovoltaic power generation elements to be synchronized under the consistency index is determined by dividing the number of power generation logs of the consistent non-environment with the number of power generation logs of all non-environments to be synchronized and the number of power generation logs of all non-environments of interest in turn.

[0027] Further, when the configuration index includes an artificial relationship index, sub-photovoltaic power generation elements to be synchronized corresponding to the artificial relationship index are clustered from the photovoltaic power generation elements to be synchronized, and the following process is used to determine the association between the sub-photovoltaic power generation elements in the area of ​​interest and the sub-photovoltaic power generation elements to be synchronized under the consistency index:

[0032] By dividing the number of negative man-made accidents to be synchronized with the number of man-made accidents to be synchronized, and dividing the number of negative man-made accidents of concern with the number of man-made accidents of concern, the correlation between the sub-photovoltaic power generation elements in the area of ​​concern and the sub-photovoltaic power generation elements to be synchronized under the consistency index is determined.

[0033] Further, when the configuration index includes a combination of an environmental index, a non-environmental index and a human relationship index, the correlation between the sub-photovoltaic power generation element in the area of ​​interest and the sub-photovoltaic power generation element to be synchronized under the environmental index, the non-environmental index and the human relationship index is calculated in sequence, and the power generation data correlation corresponding to the environmental index, the non-power generation data correlation corresponding to the non-environmental index, and the human correlation corresponding to the human relationship index are output;

[0037] Determine the importance after the environmental importance, the non-environmental importance and the human relationship importance are summed and recorded;

[0038] The division record between the cosine distance sum record and the importance sum record is determined as the photovoltaic power generation element association degree between the photovoltaic power generation element in the concerned area and the photovoltaic power generation element to be synchronized.

[0039] Furthermore, the data synchronization method further includes:

[0040] The photovoltaic power generation element to be synchronized corresponding to the photovoltaic power generation element correlation degree within the configured interference area correlation degree range is determined as the interference area photovoltaic power generation element synchronized with the photovoltaic power generation element in the focus area;

[0056] See also Figure 1 , Figure 1 A flow chart of a data synchronization method based on photovoltaic power generation provided by the present invention, such as Figure 1 As shown in the present invention, a data synchronization method based on photovoltaic power generation is provided, and the data synchronization method comprises:

[0057] S1. Collecting photovoltaic power generation elements in the area of ​​interest and several photovoltaic power generation elements to be synchronized.

[0058] In this step, discrete fault power generation data are aggregated into causally related regions, and the processing of power generation data is configured as processing of regions. Photovoltaic power generation elements in the area of ​​interest and several photovoltaic power generation elements to be synchronized are collected, wherein there are visual charts for the photovoltaic power generation elements in the area of ​​interest and the photovoltaic power generation elements to be synchronized.

[0059] S2. Clustering the photovoltaic power generation elements in the region of interest is completed by configuring indicators, and a plurality of sub-photovoltaic power generation elements in the region of interest are output.

[0060] In this step, the configuration indicators include several of the environmental indicators, non-environmental indicators and human relationship indicators. Through the above indicators, the photovoltaic power generation elements in the area of ​​interest are clustered into several parts, and several sub-photovoltaic power generation elements in the area of ​​interest are output. Some of the sub-photovoltaic power generation elements in the area of ​​interest are output through clustering of environmental indicators, some of the sub-photovoltaic power generation elements in the area of ​​interest are output through clustering of non-environmental indicators, and some of the sub-photovoltaic power generation elements in the area of ​​interest are output through clustering of human relationship indicators.

[0061] S3, for each photovoltaic power generation element to be synchronized, clustering each photovoltaic power generation element to be synchronized by using the configuration index, and outputting a number of sub-photovoltaic power generation elements to be synchronized corresponding to each photovoltaic power generation element to be synchronized;

[0062] In this step, each photovoltaic power generation element to be synchronized is also clustered according to the configuration index, so as to obtain a number of sub-photovoltaic power generation elements to be synchronized.

[0063] S4, sequentially collecting the correlation between each sub-photovoltaic power generation element in the area of ​​interest and the sub-photovoltaic power generation element to be synchronized under the consistency index in each of the photovoltaic power generation elements to be synchronized, so as to determine the photovoltaic power generation element correlation between the photovoltaic power generation element in the area of ​​interest and each of the photovoltaic power generation elements to be synchronized;

[0064] In this step, the correlation between each sub-photovoltaic power generation element in the area of ​​interest and the sub-photovoltaic power generation element to be synchronized under the consistency index in each photovoltaic power generation element to be synchronized is collected, and then the weighted sum of the correlation between all sub-photovoltaic power generation elements in the area of ​​interest and the corresponding sub-photovoltaic power generation elements to be synchronized is completed, and the photovoltaic power generation element correlation between the photovoltaic power generation element in the area of ​​interest and each photovoltaic power generation element to be synchronized is output.

[0065] Here, since there are differences in the calculation methods of the correlation between the sub-photovoltaic power generation elements in the area of ​​interest and the corresponding sub-photovoltaic power generation elements to be synchronized under different indicators, the indicator corresponding to the sub-photovoltaic power generation elements in the area of ​​interest is detected, and then the correlation between the sub-photovoltaic power generation elements in the area of ​​interest and the corresponding sub-photovoltaic power generation elements to be synchronized is decided through the correlation calculation algorithm under the indicator.

[0066] S5. The photovoltaic power generation element to be synchronized corresponding to the photovoltaic power generation element association degree within the configured association area association degree range is decided as the photovoltaic power generation element in the association area to be synchronized with the photovoltaic power generation element in the focus area.

[0067] In this step, the correlation degree range of the associated area corresponding to the associated area is collected in advance. When the photovoltaic power generation element correlation degree between the photovoltaic power generation element in the focus area and a photovoltaic power generation element to be synchronized is within the correlation degree range of the associated area, the photovoltaic power generation element to be synchronized is considered to be the photovoltaic power generation element in the associated area of ​​the photovoltaic power generation element in the focus area.

[0068] Here, a photovoltaic power generation element in a certain region of interest with a rule may be designated as a basic photovoltaic power generation element, and the method of the present invention may be used to output a list of other photovoltaic power generation elements to be synchronized with the photovoltaic power generation element in the region of interest within the range of association in the associated region.

[0069] Photovoltaic power station systems can be divided into primary systems and secondary systems. The primary system refers to the system composed of hardware equipment related to power generation and collection lines, such as combiner boxes and photovoltaic components; the secondary system refers to the hardware and software system that monitors, controls and protects the operating status of the primary power generation system, such as the comprehensive automation system of photovoltaic power stations.

[0070] The present invention provides a data synchronization method based on photovoltaic power generation, wherein the data synchronization method includes: collecting photovoltaic power generation elements in a region of interest and a number of photovoltaic power generation elements to be synchronized, clustering the photovoltaic power generation elements in the region of interest by configuring indicators, outputting a number of sub-photovoltaic power generation elements in the region of interest, and then clustering each photovoltaic power generation element to be synchronized by configuring indicators, outputting a number of sub-photovoltaic power generation elements to be synchronized corresponding to each photovoltaic power generation element to be synchronized, and sequentially collecting the correlation between each sub-photovoltaic power generation element in the region of interest and the sub-photovoltaic power generation elements to be synchronized under the consistency index in each photovoltaic power generation element to be synchronized, so as to determine the correlation between the photovoltaic power generation elements in the region of interest and each photovoltaic power generation element to be synchronized, and determining the photovoltaic power generation elements to be synchronized corresponding to the correlation of the photovoltaic power generation elements in the region of interest and the photovoltaic power generation elements to be synchronized within the range of the configured correlation area correlation as the photovoltaic power generation elements in the associated region that are synchronized with the photovoltaic power generation elements in the region of interest. In this way, the present application can cluster the regional photovoltaic power generation elements into a number of parts according to the indicators, output the overall correlation by the correlation of each part, and accurately find the photovoltaic power generation elements associated with the regional photovoltaic power generation elements.

[0071] The configuration index includes several of environmental indexes, non-environmental indexes and human relationship indexes. Further, a data synchronization method is used to determine the correlation between the sub-photovoltaic power generation elements in the concerned area and the sub-photovoltaic power generation elements to be synchronized under a certain index.

[0072] When the configuration index includes an environmental index, sub-photovoltaic power generation elements to be synchronized corresponding to the environmental index are clustered from the photovoltaic power generation elements to be synchronized, and the following process is used to determine the correlation between the sub-photovoltaic power generation elements in the focus area and the sub-photovoltaic power generation elements to be synchronized under the consistency index:

[0073] The normal power generation log to be synchronized and the abnormal power generation log to be synchronized in the sub-photovoltaic power generation elements to be synchronized, as well as the normal power generation log of interest and the abnormal power generation log of interest in the sub-photovoltaic power generation elements in the area of ​​interest are collected.

[0074] In this step, the environment includes a normal environment and an abnormal environment. Specifically, the environmental factors include temperature factors, weather factors, humidity factors, wind factors, and dust factors;

[0075] Normal conditions include at least one or more of the following:

[0076] The weather is clear, the temperature is greater than 25 degrees Celsius, the wind speed is less than level 6, and the dust PM2.5 is less than or equal to 2;

[0077] Abnormal circumstances include at least one or more of the following:

[0078] Rainy weather, temperature less than 25 degrees Celsius, wind force greater than or equal to level 6, dust PM2.5 greater than 2;

[0079] Furthermore, when the power generation log indicator is an environmental indicator, the normal power generation log and abnormal power generation log to be synchronized in the sub-photovoltaic power generation element to be synchronized, as well as the normal power generation log and abnormal power generation log of interest in the sub-photovoltaic power generation element of the area of ​​interest are output.

[0080] Affected by geographical terrain, climate conditions, and different weather conditions such as wind speed, irradiance, and cloud cover, the power differences of some distributed photovoltaic power generation in the same region may be large while some are small, and their output fluctuations may be consistent or completely different. In addition, photovoltaic aggregation has a smoothing effect, and the accuracy of aggregate prediction is generally higher than that of single-site prediction. In order to accurately obtain the regional distributed photovoltaic aggregate power generation, it is necessary to complete the aggregate division of distributed photovoltaics in the same region.

[0081] Here, according to the power generation log time sequence attribute and the power generation log position attribute of each power generation log, the power generation logs belonging to the normal power generation data are sorted, the normal power generation logs are output, and then the normal power generation logs of interest and the normal power generation logs to be synchronized are output.

[0082] Through the time sequence attribute and the position attribute of the power generation log, at least part of the normal power generation logs to be synchronized that are consistent with at least part of the normal power generation logs of interest are determined, and the number of completely consistent normal power generation logs is obtained.

[0083] In this step, when the comparison is completed, only when the time series attributes and the location attributes of the power generation log meet the consistency requirements at the same time, can the part of the normal power generation log of concern be considered consistent with the part of the normal power generation log to be synchronized, from which the number of completely consistent normal power generation logs in the part of the normal power generation log of concern or the part of the normal power generation log to be synchronized is decided.

[0084] The decision is made by dividing the number of completely consistent normal power generation logs with the total number of power generation logs in the normal power generation log to be synchronized and the total number of power generation logs in the normal power generation log of interest, and deciding the correlation degree of normal power generation data between the normal power generation log of interest and the normal power generation log to be synchronized.

[0085] Through the power generation log position attribute, at least part of the abnormal power generation logs to be synchronized that are consistent with at least part of the abnormal power generation logs of concern are determined, and the number of completely consistent abnormal power generation logs is obtained.

[0086] Calculate the division records between the number of completely consistent abnormal power generation logs and the number of power generation logs of all abnormal power generation logs to be synchronized and the number of power generation logs of all abnormal power generation logs of concern, and determine the abnormal power generation data correlation between the abnormal power generation log of concern and the abnormal power generation log to be synchronized.

[0087] The correlation between the sub-photovoltaic power generation element in the area of ​​interest and the sub-photovoltaic power generation element to be synchronized under the consistency index is determined by the correlation between the normal power generation data and the abnormal power generation data, as well as the normal importance corresponding to the correlation between the normal power generation data and the abnormal importance corresponding to the correlation between the abnormal power generation data.

[0088] Specifically, the following process is used to determine the correlation between the sub-photovoltaic power generation element in the concerned area and the sub-photovoltaic power generation element to be synchronized under the consistency index:

[0089] Determine the total number of normal power generation logs between the total number of power generation logs in the normal power generation log to be synchronized and the total number of power generation logs in the normal power generation log of interest, and determine the total number of normal power generation logs as the normal importance corresponding to the normal power generation data correlation degree;

[0090] Determine the total number of abnormal power generation logs between the number of all abnormal power generation logs to be synchronized and the number of all abnormal power generation logs of concern, and determine the total number of abnormal power generation logs as the abnormal importance corresponding to the abnormal power generation data correlation degree;

[0091] Determine the cosine distance between the correlation degree of the normal power generation data and the normal importance, as well as the cosine distance between the correlation degree of the abnormal power generation data and the abnormal importance, and record the sum of the two cosine distances as the correlation degree between the sub-photovoltaic power generation element in the area of ​​interest and the sub-photovoltaic power generation element to be synchronized under the consistency index.

[0092] It should be noted that negative refers to the complete consistency of the position attributes, and a negative abnormal environment refers to an abnormal environment in which the position attributes are completely consistent.

[0093] Finally, the correlation between normal log power generation data and abnormal power generation data is mapped.

[0094] The weighted summation method is used to complete the mapping of the correlation between the two types of power generation data, and the importance is determined by the number of normal log power generation data and abnormal power generation data.

[0095] By real-time collection of the power data output from the AC output end of the photovoltaic element, the electric energy data output within a preset interval and the incremental power generation data at the current collection moment are determined. When it is detected that the collection of the power data of the photovoltaic element is interrupted, the daily power generation data of the photovoltaic element is corrected according to the incremental power generation data. When it is detected that the collection of the power data of the photovoltaic element is not interrupted, the daily power generation data of the photovoltaic element up to the current collection moment is determined according to the incremental power generation data and the power data. Then, the power generation monitoring information of the power station is determined according to the daily power generation data of each photovoltaic element in the power station to ensure the accuracy of the data.

[0096] As a preferred embodiment, when the configuration index includes a non-environmental index, sub-photovoltaic power generation elements to be synchronized corresponding to the non-environmental index are clustered from the photovoltaic power generation elements to be synchronized, and the following process is used to determine the correlation between the sub-photovoltaic power generation elements in the area of ​​interest and the sub-photovoltaic power generation elements to be synchronized under the consistency index:

[0097] Collecting the non-environment to be synchronized in the sub-photovoltaic power generation element to be synchronized and the non-environment of interest in the sub-photovoltaic power generation element in the area of ​​interest;

[0098] Through the power generation log location attribute, the non-power generation data sub-power generation log to be synchronized is determined to be consistent with the non-power generation data sub-power generation log of interest, and the number of power generation logs in the consistent non-environment is obtained;

[0099] The correlation between the sub-photovoltaic power generation elements in the area of ​​interest and the sub-photovoltaic power generation elements to be synchronized under the consistency index is determined by dividing the number of power generation logs of the consistent non-environment with the number of power generation logs of all non-environments to be synchronized and the number of power generation logs of all non-environments of interest in turn.

[0100] In this step, the method for obtaining the relevance of the non-environment is consistent with the method for obtaining the relevance of the abnormal power generation log.

[0101] The sub-PV power generation elements in the concerned area and the sub-PV power generation elements to be synchronized are executed to determine the correlation of the non-environment, that is, the correlation between the sub-PV power generation elements in the concerned area and the sub-PV power generation elements to be synchronized under the consistency index. The correlation calculation of the non-environment is similar to the correlation calculation of abnormal power generation data, which also completes the attribute synchronization of the power generation log.

[0102] As a preferred embodiment, when the configuration index includes an artificial relationship index, sub-photovoltaic power generation elements to be synchronized corresponding to the artificial relationship index are clustered from the photovoltaic power generation elements to be synchronized, and the following process is used to determine the correlation between the sub-photovoltaic power generation elements in the area of ​​interest and the sub-photovoltaic power generation elements to be synchronized under the consistency index:

[0119] The photovoltaic power generation elements to be synchronized corresponding to the photovoltaic power generation element correlation degrees within the configured different regional correlation degree ranges are determined as different regional photovoltaic power generation elements synchronized with the photovoltaic power generation elements in the focus region.

[0120] In this step, not only the photovoltaic power generation elements in the associated area can be determined from the photovoltaic power generation elements to be synchronized, but also the photovoltaic power generation elements in the interference area and the photovoltaic power generation elements in different areas can be determined.

[0121] The interference area correlation range corresponding to the interference area and the different area correlation ranges corresponding to different areas are collected and configured, and then the photovoltaic power generation element correlation between the photovoltaic power generation element in the focus area and the photovoltaic power generation element to be synchronized is compared with the interference area correlation range and the different area correlation range in turn, so as to find out the regional photovoltaic power generation element type corresponding to the photovoltaic power generation element to be synchronized corresponding to the photovoltaic power generation element correlation, and the regional photovoltaic power generation element type here includes photovoltaic power generation elements in the associated area, photovoltaic power generation elements in the interference area and photovoltaic power generation elements in different areas.
