[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0019] As Figure 1 shown, the embodiment of the present invention provides an intelligent optical storage charging inspection energy collaborative optimization control method, and the method includes the following steps: Step S100, collect the historical information of photovoltaic power generation in the charging station, and predict the high-frequency fluctuation period of each charging station based on the historical information; for details, please refer to Figure 2 .

[0020] Step S101, collect the historical information of photovoltaic power generation in the charging station, and train a neural network model with the historical information of photovoltaic power generation in the charging station to obtain a fluctuation prediction model; The specific steps to establish the fluctuation prediction model are as follows: Collect historical information data of photovoltaic power generation from the monitoring systems of each charging station. These data should include the output power of photovoltaic power generation and the corresponding timestamps. The data collection period can be set according to actual needs, such as weekly, monthly, etc. Clean the collected data to remove outliers, missing values, duplicate values, etc., and ensure the accuracy and integrity of the data. Preprocess the data according to the preset output power and fluctuation duration thresholds. Identify the data segments where the output power of photovoltaic power generation does not meet the preset output power and the fluctuation duration exceeds the preset time length, and mark them as one fluctuation. Count the number of fluctuations and the average duration of each fluctuation in each charging station within each historical period. Divide the preprocessed data into a training set and a validation set. Extract features from the preprocessed data. These features can include the historical number of fluctuations, average duration, time (such as hours, dates, seasons), weather conditions (such as sunny, cloudy, rainy), temperature, humidity, etc. The selection of features should be based on the actual situation and the requirements of the neural network model. The model can choose models suitable for processing time series data, such as Recurrent Neural Network (RNN), Long Short-Term Memory Network (LSTM), Gated Recurrent Unit (GRU), etc. Use a deep learning framework (such as TensorFlow, PyTorch, etc.) to build a neural network model. Use the training set data to train the neural network model, and use the validation set data to evaluate the performance of the model until the preset performance requirements are met, then the trained fluctuation prediction model can be obtained.

[0021] Step S102: Predict the fluctuation information of photovoltaic power generation in each charging station within each period according to the fluctuation prediction model. The fluctuation information includes the number of fluctuations and the average duration of each fluctuation in the photovoltaic power generation of each charging station. In this step, by inputting the time corresponding to each period within a year into the fluctuation prediction model, the fluctuation information of photovoltaic power generation in each charging station within each period of the year can be output.

[0022] Step S103: Determine whether the photovoltaic power generation of each power station is a high-frequency fluctuation period in each period based on the number of fluctuations in the fluctuation information and the preset fluctuation threshold. Among them, "fluctuation" means that when the output power of photovoltaic power generation does not meet the preset output power and the fluctuation duration exceeds the preset time length, it can be counted as one fluctuation. The time step of a period may be a week, a month, or a season. A high-frequency fluctuation period refers to a period in which the number of fluctuations within a period exceeds the preset fluctuation threshold and is determined as a high-frequency fluctuation period.

[0023] Step S200, when the photovoltaic power generation in the charging station is in a high-frequency fluctuation cycle at the current moment, determine the monitoring frequency of meteorological data according to the average duration of each fluctuation predicted by the fluctuation prediction model, and adjust the power supply mode according to the meteorological data. The power supply mode includes a first power supply mode and a second power supply mode; for details, please refer to Figure 3 .

[0024] Step S201, when the photovoltaic power generation in the charging station is in a high-frequency fluctuation cycle at the current moment, determine the monitoring frequency of meteorological data according to the average duration of each fluctuation predicted by the fluctuation prediction model; the average duration here refers to the average duration of each fluctuation within the current high-frequency fluctuation cycle predicted by the fluctuation prediction model; the larger the average duration, the lower the corresponding monitoring frequency, and the smaller the average duration, the higher the corresponding monitoring frequency. There is a negative correlation between the average duration and the monitoring frequency. Step S202, when it is detected that the meteorological data is abnormal, adjust the power supply mode to the second power supply mode until the th minute after the abnormality ends, restore the power supply mode from the second power supply mode to the first power supply mode. The value of is determined according to the number of fluctuations within the current high-frequency fluctuation cycle predicted by the fluctuation prediction model. Here, the number of fluctuations has a positive correlation with the value. The larger the number of fluctuations, the larger the corresponding value; determining whether the meteorological data is abnormal includes the following steps: continuously collect meteorological data such as sunlight intensity using sensors or weather stations and preprocess it: clean the collected data, remove noise and outliers (such as extreme values caused by sensor failures), and perform necessary smoothing processing; set the abnormal conditions for sunlight intensity according to historical data and business requirements. For example, if the sunlight intensity suddenly drops below a certain threshold and remains for a preset duration (such as continuously for several minutes), it is considered abnormal; perform real-time monitoring on the preprocessed meteorological data to ensure the accuracy and real-time nature of the data. Compare the real-time monitored sunlight intensity with the set threshold. If it meets the abnormal conditions, determine that the meteorological data is abnormal and adjust the power supply mode.

[0025] Among them, the first power supply mode is: supply power to the electric vehicle mainly through photovoltaic power generation and supplemented by an energy storage system (specifically, preferentially use the electric energy generated by photovoltaic power generation. When the electric energy generated by photovoltaic power generation is insufficient to support the power supply to the electric vehicle, the energy storage system assists in supplying power to the electric vehicle to meet the charging demand). At this time, if there is surplus electric energy generated by photovoltaic power generation after meeting the power supply to the electric vehicle, store the surplus electric energy of photovoltaic power generation in the energy storage system. The second power supply mode is: mainly using the energy storage system and supplemented by the power grid to supply power to electric vehicles (specifically: preferentially using the energy storage system to supply power to electric vehicles, and when the remaining power in the energy storage system is less than the preset power, using the power grid to supply power to electric vehicles). At this time, the photovoltaic power generation does not supply power to electric vehicles, and the photovoltaic power generation stores electrical energy through the energy storage system).

[0026] Step S300, when the photovoltaic power generation in the charging station is not in the high-frequency fluctuation period at the current moment, determine that the monitoring frequency of the meteorological data is the fixed preset frequency, and adjust the power supply mode according to the meteorological data. For details, please refer to Figure 4 .

[0027] Step S301, when the photovoltaic power generation in the charging station is not in the high-frequency fluctuation period, determine that the monitoring frequency of the meteorological data is the fixed preset frequency; the fixed preset frequency is usually less than the monitoring frequency determined according to the average duration. Step S302, when it is detected that the meteorological data is abnormal, make the power supply mode the second power supply mode until the th minute after the abnormality ends, restore the power supply mode from the second power supply mode to the first power supply mode; The value of is determined according to the number of fluctuations in the current period predicted by the fluctuation prediction model. The number of fluctuations is positively correlated with the value of. The larger the number of fluctuations, the larger the corresponding value of. Usually is less than .

[0028] In the present invention, based on the fluctuation prediction model, the fluctuation information of the photovoltaic power generation in each charging station in each period is predicted. Based on the fluctuation information, it is determined whether each period is a high-frequency fluctuation period. When the photovoltaic power generation in the charging station is in the high-frequency fluctuation period at the current moment, the monitoring frequency of the meteorological data is determined by the average monitoring duration of each fluctuation. When the photovoltaic power generation in the charging station is not in the high-frequency fluctuation period at the current moment, it is determined that the monitoring frequency of the meteorological data is the fixed preset frequency, and the power supply mode is adjusted according to the meteorological data. In the present invention, the monitoring frequency and the power supply mode are dynamically adjusted to cope with the volatility of the photovoltaic power generation and the abnormality of the meteorological data. This strategy optimization not only improves the stability and reliability of the system, but also reduces the operating cost and the impact on the power grid; it can effectively improve the operation efficiency and stability of the charging station, and reduce the impact of photovoltaic power generation fluctuations and meteorological anomalies on electric vehicle charging.
