Description

Artificial intelligent deviation rectifying method and device for heliostat, electronic equipment and storage medium

Technical Field

The disclosure relates to the technical field of solar energy application, and more particularly to an artificial intelligence deviation rectifying method and device for a heliostat, an electronic device and a storage medium.

Background

Solar energy is increasingly utilized in human life due to its advantages of large total energy, wide distribution, cleanliness, no pollution and high economy. In the process of utilizing solar energy, whether using solar photovoltaic panels, solar concentrating mirrors or other forms, sunlight tracking technology is increasingly being used in order to receive more solar radiation for utilization. Especially in a large-scale solar power station, the sunlight tracking system can be used to improve the power generation efficiency of the solar power generation device so as to improve the yield.

For example, when the sunlight tracking technology is applied to solar photovoltaic power generation, a control system of the sunlight tracking technology calculates according to a tracking formula obtained by a mathematical principle to control a solar photovoltaic cell panel to track so as to keep the photovoltaic cell panel to face the sun at any time, and light rays of sunlight vertically irradiate the photovoltaic cell panel at any time; when the solar energy heat collection system is applied to the tower type solar energy heat generation system, the control system calculates according to a tracking formula obtained by a mathematical principle to control the movement of the reflector in real time so as to reflect sunlight to the heat collection tower at any time.

After various measurements and initial installation and debugging are carried out on the photovoltaic cell panel and the reflector, fixed input state parameters for carrying out mathematical principle calculation, such as longitude and latitude parameters of the photovoltaic cell panel and the reflector, an inclination angle and an altitude of an installation base and the like, are obtained, and at the initial stage, the precision of the parameters is high, and the precision of equipment tracking is also high. However, as the equipment operates, due to the influence of wind, vibration, geographical conditions and mechanical stress, these parameters change gradually, and errors accumulate gradually, eventually resulting in a significant drop in tracking accuracy.

In this regard, the prior art provides various methods for obtaining tracking errors, i.e., offsets, tracked by the individual photovoltaic panels or mirrors at different times. In addition, the prior art also describes a method for fitting a tracking error curve according to the obtained discrete tracking error, calculating the current tracking error in real time by using the tracking error curve, and correcting the current tracking parameter according to the current tracking error curve to perform accurate tracking.

The method for calculating the current tracking error by fitting the tracking error curve according to the historical deviation value is low in speed, high in consumed calculation resource and low in accuracy of the fitted result.

Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are some embodiments of the present disclosure, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.

The heliostat referred to in the present disclosure may be a reflector which tracks the moving track of the sun in real time and reflects the sunlight to a specific position by using mirror reflection, which is common in a concentrated solar thermal power station, or a photovoltaic cell panel which tracks the sunlight in real time by a solar photovoltaic power station tracked in dual axes to face the incident direction of the sunlight, as long as the heliostat needs to form certain specific angles with the sunlight in real time to use the energy of the sunlight. The heliostat used in the embodiment of the present disclosure takes a heliostat used in a tower-type concentrated solar thermal power plant as an example, and adjusts the posture of a mirror surface in an azimuth-elevation manner to track the sunlight, and reflects the sunlight onto a concentrated heat collector fixed at a certain position.

Fig. 1 shows a schematic flow chart of an artificial intelligence deviation rectifying method for a heliostat according to an embodiment of the present disclosure. The heliostat artificial intelligence deviation rectifying method can comprise the following steps:

s11, reading sample data;

s13, training an LSTM network according to the sample data to obtain an LSTM network model;

s15, inputting the sequential data of the heliostat into an LSTM network model, and outputting the deviation correcting data of the heliostat after calculation by the LSTM network model; and

and S17, correcting the daily tracking operation parameters of the heliostat by using the deviation correction data of the heliostat.

In the embodiment of the disclosure, since the heliostat tracks in a dual-axis manner of pitch plus azimuth, the tracking operation parameters of the heliostat include an azimuth angle and a pitch angle of the heliostat. The operation parameters may also include other parameters that define the attitude of the heliostat according to the operation tracking mode of the heliostat, which is not limited by the present disclosure.

The sample data of the heliostat in S11 is the sample data used for training the model, and may include data reflecting deviation amount of the heliostat at different time, status position data of the heliostat itself, other relevant data of the heliostat field, sample deviation correction data obtained by calculation, and other data related to training. Wherein all data except the sample deskew data may be collectively referred to as sample sequence data. In the embodiment of the present disclosure, the data about the deviation amount is obtained by recording an initial operating parameter for controlling the heliostat to irradiate the light spot on a certain light target center (at this time, although an instruction for controlling the heliostat to irradiate the light spot on the light target center is issued, the light spot will deviate from the light target center due to the existence of a tracking error) and a corrected operating parameter for actually irradiating the light spot on the light target center after calibration; and the sample rectification data is determined by performing regression operation according to the data related to the deviation amount and other related data of the equipment and the mirror field. The deviation correcting data can be used for adjusting an orientation-pitching tracking formula of the heliostat, so that more accurate tracking operation parameters can be obtained through the adjusted orientation-pitching tracking formula to perform more accurate tracking operation. The data reflecting the deviation amount of the heliostat at different time points can be obtained by other methods, such as a method of directly observing the state of the heliostat by using a camera or a method of installing various sensors on the heliostat, as long as the obtained data can reflect various differences of the operation parameters before and after the calibration of the heliostat.

The LSTM (Long-Short Term Memory) Network in S13 is a Long-Short Term Memory Neural Network, which is one of Recurrent Neural Networks (RNN). The general RNN is greatly influenced by short-term memory, and important information in the early stage can be gradually omitted when the general RNN is learned to the later stage. The LSTM incorporates a mechanism for adjusting the flow of information, and can memorize necessary data and forget useless data. The sample trained LSTM network may be saved as an LSTM network model for later use.

In S15, the sequence data including the deviation characteristic acquired when the heliostat is currently operating is input as input data to the LSTM network model stored after training, and the rectification data output from the LSTM network model can be acquired. The deviation correcting data is the deviation correcting data corresponding to the sequence data of the heliostat during the current operation, namely the deviation correcting data can be used for correcting the deviation of the heliostat during the current operation with higher precision.

In S17, the deviation correcting data is used for adjusting the orientation-pitching tracking formula of the heliostat, so that the real-time tracking operation parameters of the heliostat are corrected, the heliostat tracking effect with higher precision is obtained, and the efficiency of the power plant is ensured.

Therefore, the LSTM network model which can be used for generating heliostat deviation correction data is obtained by training the LSTM network by using the sample data, the calculation amount in the process is small, the calculation speed is high, and the deviation correction data can be obtained more conveniently; the LSTM network can transmit related information along a long-chain sequence to perform long-term memory, and the trained LSTM network model has higher accuracy of an output result due to the long-term memory of useful information in sample data when in use.

Fig. 2 shows a schematic flow chart of training an LSTM network according to sample data in the heliostat artificial intelligence deviation rectification method according to an embodiment of the present disclosure. Training the LSTM network according to the sample data in S13, and obtaining the LSTM network model may include:

s131, preprocessing sample data, wherein the sample data comprises sample sequence data and sample deviation correcting data;

s133a, in LSTM network, connecting preprocessed sample sequence data as input with a first LSTM hidden layer with a first number of units, the first LSTM hidden layer is connected with a first discarding layer, and the first discarding layer is connected with output sample deviation correcting data through a full connection layer; and

and S135, performing iterative optimization training on the LSTM network by using an optimizer to obtain an LSTM network model.

In S131, the sample data is preprocessed to be processed into a data format suitable for and capable of being directly input to the LSTM network for learning.

In S133a, the preprocessed sample data is connected as input to a first LSTM hidden layer with 100 cells, which is then connected to a first drop layer (drop layer) to regularize the parameters in the network using the drop layer, where the drop rate of the first drop layer is 0.4. The first number is not limited to 100, the discarding rate of the first discarding layer is not limited to 0.4, and the first number may be selected by comprehensive consideration of the implementer according to the dimensions of the sample data, the number of samples, the consumption of the computing resources, and other factors. The effect of using the discard layer is to prevent over-fitting of the data so that the finally obtained LSTM network model can output accurate results.

And in S133a, the first discarding layer is connected to the sample correction data as an output through the full-link layer, and the full-link layer is used to convert the nonlinear calculation into a linear calculation, so as to output a result.

In S135, since the input and output of the LSTM network are determined, the LSTM network may be iteratively optimally trained by the optimizer to optimize various parameters in the neural network and learn the characteristics of the sample data.

FIG. 3 is a schematic flow chart illustrating training of an LSTM network according to sample data in an artificial intelligence deviation rectification method for a heliostat according to another embodiment of the disclosure. Training the LSTM network according to the sample data in S13, and obtaining the LSTM network model may include:

s133b, in LSTM network, connecting preprocessed sample sequence data as input with a first LSTM hidden layer with a first number of units, the first LSTM hidden layer is then connected with a first discarding layer, the first discarding layer is then connected with a second LSTM hidden layer with a second number of units, the second LSTM hidden layer is then connected with a second discarding layer, and the second discarding layer is connected with output sample deviation rectifying data through a full connection layer; and

In S133b, in addition to including the first LSTM hidden layer and the first discard layer as in S133a, the first discard layer is further connected to a second LSTM hidden layer having 200 cells, which is then connected to a second discard layer, wherein the discard rate of the second discard layer is 0.5. The second number is not limited to 200, the discarding rate of the second discarding layer is not limited to 0.5, and the second number may be selected by comprehensive consideration of the implementer according to the dimensions of the sample data, the number of samples, the consumption of the computing resources, and the like.

And in S133b, the second discarding layer is connected to the sample rectification data as an output through the full connection layer to convert the nonlinear calculation into a linear calculation for outputting the result.

The method flow shown in fig. 3 introduces a second LSTM hidden layer and a second discarded layer with a second number of units in S133b, and the second number is different from the first number, and the discard rate of the first discarded layer is different from the discard rate of the second discarded layer. The two pairs of parameters are selected by the practitioner according to various factors of practical considerations, but not limited to the first unit number of 100, the second unit number of 200, and the discard rate of the first discard layer of 0.4 and the discard rate of the second discard layer of 0.5, which are described in this disclosure, they may be the same.

In some embodiments, when the complexity of the project is high and the requirement on the accuracy of the result is high, a method of introducing a second LSTM hidden layer and a second discarded layer as shown in fig. 3 may be adopted, so that an LSTM network model with high accuracy can be obtained through further computational learning. And in some other embodiments, the similar steps may be repeated multiple times according to actual situations to obtain the LSTM network model with higher accuracy, which is not limited by the present disclosure.

Therefore, the hidden layer is trained by using the sample data, then the hidden layer and the discarded layer are repeatedly used for training, and under the condition that the total number of units of the hidden layer is equal, the training result is better than that of the training by directly using a single hidden layer. Therefore, the LSTM network model with higher accuracy can be obtained by relatively reducing the number of LSTM hidden layer units, and resources are saved.

In some embodiments, the first number is less than the second number and the drop rate of the first drop layer is less than the drop rate of the second drop layer, i.e. the number of cells of the first-in LSTM hidden layer is less than the number of cells of the second-in LSTM hidden layer and the drop rate of the first-in drop layer is less than the drop rate of the second-in drop layer. Therefore, less LSTM hidden layer units are used for carrying out preliminary training on sample data, a smaller discarding rate is set, more useful information is reserved, and a preliminarily formed LSTM network is obtained; and then more accurate training is carried out on the sample data by using more LSTM hidden layer units, and a larger discarding rate is set, so that a more accurate LSTM network is obtained. The structures of the units in the first hidden layer and the second hidden layer may be the same or different according to the characteristics of the items, and the disclosure does not limit this. By setting the number of LSTM hidden layers and the discarding rate of the discarded layers, an LSTM network model with higher accuracy can be obtained with less computing resources.

Fig. 4 shows a schematic flow chart of preprocessing sample data in the heliostat artificial intelligence deviation rectifying method according to an embodiment of the present disclosure. The preprocessing of the sample data in S131 may include:

s1311, splicing all groups of data of the same heliostat in the same day into a matrix;

s1313, obtaining a sample cell array by using the cell array combination matrix; and

s1315, processing the sample cell array to enable the sample cell array to be distributed in a normalized mode between 0 and 1, and storing the mean value and the standard deviation.

In S1311, sample data of the same heliostat on the same day is spliced into a matrix. Where there are about 10000 heliostats in the disclosed embodiment, each heliostat may have multiple days of data, i.e., multiple sets of sample data, and there may be multiple sets of sample sequence data for each heliostat each day. Each sample sequence data comprises 20 rows of parameters, and the parameters record data such as deviation amount of heliostat tracking, state parameters of the heliostat, related parameters of a heliostat field and the like; the daily sample correction data contains 4 columns of parameters, and the parameters record the sample correction data which is obtained after regression calculation and is used for adjusting the tracking formula to obtain the calibrated tracking operation parameters. Firstly, selecting 6 sample sequence data with 20-row parameters of the same heliostat on the same day for all heliostats and splicing the data into a 20 multiplied by 6 matrix; and the sample deviation correcting data only have 1 piece each day, and each 4 columns are spliced into a matrix of 1 x 4. The selected sample sequence data of the same heliostat on the same day is preferably at least 6 groups, so that enough useful information is provided for the LSTM network to learn, and the accuracy of the training result is ensured.

In S1313, all matrices are combined into a sample cell array, where sample sequence data is combined into an array XTrain; the sample deskew data is combined into the array YTrain. The cellular array is a special data combination type, and the internal elements of the cellular array can belong to different data types, so that the cellular array can be combined as a whole to perform subsequent steps, and operation and calculation are facilitated.

In S1315, XTrain and YTrain are processed to be normalized and distributed between 0 and 1 to be suitable for input into the LSTM network, so that the training process of the LSTM network is accelerated. The mean and standard deviation are preserved during normal distribution to facilitate their reduction in subsequent processes.

In some embodiments, the optimizer used to train the LSTM network in S135 is a gradient descent optimizer with an initial learning rate of 0.01, a piecewise descent learning rate of 0.5 is selected, and the descent factor is decreased every 30 rounds, i.e., the learning rate x piecewise descent factor is updated to a new learning rate. During the training process, the minimum Batch Size (Batch Size) of each training is 10, and the maximum number of rounds is 80. The parameters such as the learning rate, the segment descent factor, the descent turn, and the like can be selected by the implementer in a comprehensive consideration according to the characteristics of the sample data, the consumption condition of the computing resources, and the like, and the values used in the embodiment are not limited. Due to the adoption of the gradient descent optimizer, the gradient calculation speed is high, the tolerance to noise is high, the convergence is easy, and the training speed is high when the data set is large, so that the training speed and the training efficiency are improved.

In some embodiments, in addition to tuning optimization during training, reading data from the database and preprocessing may take a significant amount of time, taking all the grouped mirror queues by mirror number and date, and taking only 6 pieces of data per group modulo.

In certain embodiments, two fully-connected layers may be included to allow better engagement with the output.

In some embodiments, some sample data may be reserved before training as test data to test the trained LSTM model after obtaining the model, and the mean square error of the output of the test data and the output of the model calculation and the accuracy within the fault tolerance range are compared, and based on this, the training process is optimized to obtain a more accurate model.
