In particular, the photovoltaic system is a new energy system capable of automatically generating electric energy based on solar radiation and illumination, so that the operation of the photovoltaic system is highly dependent on the environmental conditions of the region where the photovoltaic system is located. Each region in this embodiment where the photovoltaic system is disposed may be a target region. Environmental information of multiple modes, such as environmental temperature, environmental air quality, sky images, etc., can be acquired in the target area to reflect environmental conditions in the target area.

And then recoding is carried out according to the semantic information to obtain recoded data of the environment information, so that the modes of the environment information are unified. And finally, inputting each recoded data into a target prediction model which is trained in advance, wherein the target prediction model is trained by a large amount of training data, and a complex mapping relation between input and output is learned, so that the output power of the photovoltaic system in the current environment can be automatically predicted based on each recoded data input, and the predicted output power is obtained. According to the embodiment, the output power of the photovoltaic system is predicted through the environmental information of a plurality of different modes, so that the accuracy and the reliability of a prediction result can be improved.
For example, assume that the plurality of environmental information includes sky images, temperature data, wind sound audio of the target area. Extracting semantic information of the sky image into multi-cloud-quantity-uniform cloud distribution-deep blue sky color through a semantic template of the sky image, and determining recoded data 1 according to the semantic information; extracting semantic information of temperature data to be high temperature through a semantic template of the temperature data, and determining recoded data 2 according to the semantic information; extracting semantic information of the sky image into strong wind power-high wind speed through a semantic template of wind sound audio, and determining recoded data 3 according to the semantic information. And then inputting the recoded data 1, 2 and 3 into a target prediction model to obtain the predicted output power of the photovoltaic system of 1 kilowatt.
In one implementation manner, the obtaining, according to each semantic template, semantic information corresponding to each environmental information includes:
acquiring characteristic information corresponding to the environment information aiming at each piece of environment information;
and filling a plurality of filling areas in the semantic template of the environment information according to the characteristic information to obtain the semantic information, wherein each filling area corresponds to different basic information types.
Specifically, in this embodiment, for the environmental information of each modality, the corresponding semantic template is set in advance. The semantic template comprises a plurality of filling areas, and each filling area corresponds to an important basic information category of the environment information. After the environmental information is obtained, the environmental information is subjected to feature extraction to obtain the feature information of the environmental information. And then filling each filling area in the semantic template one by one based on the characteristic information to obtain the semantic information of the environment information. According to the embodiment, important semantic information of the environment information can be extracted rapidly in a template filling mode, the information quantity can be simplified while the integrity of the information is ensured, and the reliability of a subsequent prediction result and the processing efficiency of a target prediction model are improved.
For example, assume that the plurality of environmental information includes sky images, temperature data, wind sound audio of the target area. The filling bits are represented in the semantic templates [ in ]. The semantic template of the sky image is cloud quantity, cloud distribution, sky color, extracted semantic information is cloud quantity, even sky color, and recoded data 1 is determined according to the semantic information; the semantic template of the temperature data is the temperature, the extracted semantic information is the temperature, and recoding data 2 is determined according to the semantic information; the semantic template of the wind sound audio is wind power, the extracted semantic information is wind power, and the extracted semantic information is high wind speed.
In one implementation manner, the determining recoded data corresponding to each piece of environment information according to the semantic information of each piece of environment information includes:
for each piece of environment information, a mapping table and filling content corresponding to each filling area in the semantic information of the environment information are obtained, wherein the mapping table comprises a plurality of standard filling contents and codes corresponding to each standard filling content;
determining target codes corresponding to each filling area according to the mapping table and the filling content of each filling area;
and determining the recoded data corresponding to the environment information according to each target code.
Specifically, in order to implement fast encoding, in this embodiment, a mapping table corresponding to each filling area is set in advance for each filling area, where the mapping table is used to reflect a plurality of preset standard filling contents and respective corresponding encodings, and the filling contents corresponding to the filling area are compared with the mapping table, so that a target encoding corresponding to the filling contents can be fast determined.
For example, the mapping table of the filling area corresponding to the cloud amount is shown in the following table 1, the mapping table of the filling area corresponding to the cloud distribution is shown in the following table 2, and the mapping table of the filling area corresponding to the sky color is shown in the following table 3.
TABLE 1 mapping table of filling area corresponding to cloud cover
。
TABLE 2 mapping table of filling area corresponding to cloud distribution
。
TABLE 3 mapping table of filling area corresponding to sky color
。
If the semantic information extracted from the sky image is the cloud quantity of more than one, the cloud distribution of even, the sky color of deep blue, the target code of the cloud quantity of more than one is determined to be 3 according to the table 1, according to the method, the target code of the [ even ] cloud distribution is determined to be 01 according to the table 2, the target code of the [ deep blue ] sky color is determined to be 003 according to the table 3, and the recoded data corresponding to the sky image is 3-01-003.
In one implementation manner, the determining, according to the mapping table and the padding content of each padding area, the target code corresponding to each padding area includes:
for each filling area, obtaining the similarity between the filling content corresponding to the filling area and each standard filling content corresponding to the filling area;
determining target standard filling content according to the similarity corresponding to each standard filling content;
and determining the target code corresponding to the filling area according to the code corresponding to the target standard filling content.
Specifically, in the comparison process of the filling content and the mapping table in this embodiment, the similarity between the filling content and each standard filling content in the mapping table is actually calculated, and finally, the standard filling content with the highest similarity is used as the matching object corresponding to the current filling content. And determining the target code corresponding to the current filling content through the code of the matching object in the mapping table. According to the embodiment, the codes corresponding to the filling content can be rapidly determined in a similarity calculation mode, and the coding efficiency is improved.
In one implementation, the environmental information includes an image of the sky, temperature data, and wind sound audio.
Specifically, because the information such as the quantity and the distribution condition of the cloud cover can influence the efficiency and the yield of the photovoltaic system, and the sky image can intuitively reflect the information related to the cloud cover, the sky image is taken as the environment information of one mode in the embodiment. Secondly, the photovoltaic efficiency is greatly influenced by the ambient temperature, the output power of the photovoltaic system is reduced due to the fact that the air temperature is too high, and the generated energy is also reduced, so that the temperature data is used as the environmental information of one mode in the embodiment. In addition, wind energy also affects the temperature of the photovoltaic system. Generally, the surface temperature of the photovoltaic system is higher than that of the ambient air, and wind cools the photovoltaic system, so that the efficiency and yield of the photovoltaic system in a warm environment are improved, and therefore the wind sound audio is taken as the environmental information of one mode in the embodiment.
In one implementation, the target prediction model is an attention model, and inputting each recoded data into the target prediction model to obtain a predicted output power corresponding to the photovoltaic system, including:
determining the environmental state of the target area according to the environmental information, and determining weight labels corresponding to the recoded data according to the environmental state;
splicing the recoded data containing the weight labels to obtain weight recoded data;
and inputting the weight coded data into the target prediction model to obtain the predicted output power.
Specifically, the photovoltaic efficiency is affected by various factors, and the influence degree of each influence factor on the output power of the photovoltaic system is different in different environment states, so that when the output power is predicted, the current environment state needs to be judged first, then the influence degree of each environment information on the predicted result is determined, and further different weight labels are given to each environment information, so that the accuracy of the predicted result is improved. For example, in a high-temperature environment state, the influence of temperature on the photovoltaic efficiency is obviously larger than other influencing factors, and the weight of temperature data is obviously larger than that of environment information of other modes; in the strong wind environment state, the influence of wind speed/wind power on the photovoltaic efficiency is obviously larger than other influencing factors, and the weight of wind sound audio frequency is obviously larger than that of environment information of other modes. And splicing the recoded data containing the weight labels to obtain the weight recoded data. And finally, inputting the model into a target prediction model constructed by adopting the attention model. The target prediction model can give different attention degrees according to the weights of different coded data, so that more attention degrees are put on the coded data with higher importance degree, and finally, the prediction output power with high reliability and high accuracy is output.
In one implementation, the determining the environmental state of the target area according to each environmental information includes:
acquiring characteristic information corresponding to each environmental information;
and inputting the characteristic information into a state classification model to obtain the environment state.
Specifically, in this embodiment, a state classification model is trained in advance, input data of the state classification model is characteristic information of multi-mode environmental information, and output data is a current environmental state. Because the state classification model is trained by a large amount of training data and a complex mapping relation between input and output is already learned, the current environment state can be accurately judged based on the input multi-mode environment information. The embodiment combines the deep learning technology and the environment information, and can rapidly and accurately judge the current environment state.
