[0070] The generation of energy allocation plans for different time periods and under different preset conditions based on the predicted photovoltaic power generation and power load demand also includes:
[0071] The predicted photovoltaic power generation and power load demand data are divided according to the time series to form a plurality of continuous time period sets, each of which contains the photovoltaic power generation prediction value and the power load demand prediction value in the corresponding time period;

[0078] Based on the selected optimal solution, the energy supply management of the energy storage unit of the photovoltaic energy storage system is carried out, including setting the charging and discharging strategy of the photovoltaic energy storage system, controlling the input and output power of the photovoltaic energy storage system, etc.
[0079] The real-time collection of the operating data of the energy storage unit, the evaluation of the efficiency level of the energy storage unit, and the modification of the energy allocation plan according to the evaluation results also include:
[0080] The operating data of the photovoltaic energy storage system is collected in real time through sensors, including key parameters such as power, temperature, voltage, and current of the photovoltaic energy storage system.
[0081] Data analysis technology is used to process and analyze the collected operating data to evaluate the efficiency level of the photovoltaic energy storage system, including energy storage efficiency, cycle life, etc.
[0082] According to the evaluation results, the energy allocation plan is revised, such as adjusting the charging and discharging strategy of the photovoltaic energy storage system, optimizing the energy allocation ratio, etc., to improve the efficiency of the photovoltaic energy storage system and extend its service life.
[0083] The energy supply test of the photovoltaic energy storage system is performed respectively through each energy configuration scheme in the revised energy allocation plan, and the energy configuration scheme with the highest priority weight is selected as the final energy supply execution scheme, which also includes:
[0084] Apply each energy configuration scheme in the revised energy allocation plan to the photovoltaic energy storage system for energy supply testing;
[0085] During the test, the operating status and performance indicators of the photovoltaic energy storage system are monitored in real time, such as system stability and energy utilization efficiency.
[0086] According to the monitoring results, the energy configuration plan with the highest priority weight is selected as the final energy supply implementation plan. The priority weight can be determined based on multiple factors, such as energy cost, environmental impact, system efficiency, etc.
[0087] In the specific implementation, first, we use the sensors and network of the photovoltaic energy storage system itself to collect environmental data, such as temperature, humidity, light intensity, etc. and historical power generation data, such as power generation and power generation efficiency in the past period of time. At the same time, we use the established network meteorological service platform to obtain weather forecast data for the future period of time, including but not limited to sunshine time, cloud cover, wind speed, etc.
[0088] Next, the collected environmental data, historical power generation data and weather forecast data are used to train the photovoltaic power generation prediction model and the power load demand prediction model. This step includes obtaining multidimensional data samples that integrate weather forecast data and photovoltaic energy storage system data, performing deep feature extraction, and generating feature vectors that characterize meteorological variation and photovoltaic energy storage system performance. These feature vectors are then deep encoded to obtain fine-grained feature vectors. These fine-grained feature vectors are dynamically integrated to generate a comprehensive target feature vector, which is used to calculate the dynamic alignment loss of the photovoltaic power generation prediction model, thereby dynamically adjusting and optimizing the model parameters.
[0089] Based on the trained prediction model, we predict the photovoltaic power generation and power load demand in the future. Then, we divide the prediction data into multiple continuous time period sets according to the time series. Each set contains the predicted value of photovoltaic power generation and power load demand in the corresponding time period. For each time period set, we set different energy allocation strategies according to preset conditions, such as the safe and stable operation requirements of the power grid, the charging and discharging efficiency and life management of the photovoltaic energy storage system, as well as energy costs, environmental constraints, and system stability requirements. We also calculate the allocation ratio and specific values of each energy type in each time period to generate a preliminary energy allocation plan. We verify and adjust the generated plan to ensure that it meets all preset conditions.
[0090] Then, based on preset evaluation indicators, such as lowest energy cost, smallest environmental impact, highest system efficiency, etc., we conduct a comprehensive evaluation of the multiple energy allocation plans generated, and select the energy configuration plan with the best comprehensive evaluation as the optimal plan for the current time period and preset conditions. Based on the selected optimal plan, we manage the energy supply of the energy storage unit of the photovoltaic energy storage system.
[0091] During the energy supply process, we use sensors to collect real-time operating data of the photovoltaic energy storage system, such as the power, temperature, and voltage of the energy storage unit. We use data analysis technology to process and analyze these data to evaluate the efficiency level of the photovoltaic energy storage system. Based on the evaluation results, we dynamically adjust the energy allocation plan to optimize the system's operating efficiency and stability.
[0092] Finally, each energy configuration scheme in the revised energy allocation plan is applied to the photovoltaic energy storage system for energy supply testing. During the test, we monitor the system's operating status and performance indicators in real time, such as power generation efficiency, energy storage efficiency, system stability, etc. According to the monitoring results, we select the energy configuration scheme with the highest priority weight as the final energy supply execution plan to achieve the optimal allocation of the photovoltaic energy storage system.
[0093] A computer-readable storage medium is also provided, the computer-readable storage medium includes a photovoltaic energy storage allocation method program, and when the photovoltaic energy storage allocation method program is executed by a processor, the steps of the photovoltaic energy storage allocation method as described above are implemented.

[0102] The test and solution determination module is used to perform energy supply tests on the photovoltaic energy storage system through each energy configuration solution in the revised energy allocation plan, and select the energy configuration solution with the highest priority weight as the final energy supply execution solution.

The system is installed in the control center of the photovoltaic energy storage system to ensure smooth data interaction and command transmission among all modules.
[0104] After the system is built, initial settings are performed, including setting the frequency of data collection, the scheduled tasks of the meteorological data acquisition module, the training parameters of the prediction model, etc. At the same time, energy allocation plan templates under different conditions are defined and preset to provide a basis for the subsequent automatic generation of plans.
[0105] The data acquisition module regularly collects environmental data such as temperature, humidity, light intensity, etc. and historical power generation data such as power generation and power generation efficiency from the sensor network of the photovoltaic energy storage system. These data will be stored in the system's database for subsequent analysis and prediction.
[0106] The meteorological data acquisition module obtains the weather forecast data for the next week on a regular basis every day through the established online meteorological service platform, including light intensity, temperature, wind speed, etc. These data are also stored in the database and used together with environmental data and historical power generation data to train the prediction model.
[0107] The prediction model module uses the collected environmental data, historical power generation data and weather forecast data, and adopts machine learning algorithms such as time series analysis and neural networks to train photovoltaic power generation prediction models and power load demand prediction models. These models can predict photovoltaic power generation and power load demand in the future. In order to improve the accuracy of the prediction, the model needs to be updated and retrained regularly. Whenever new data is collected and stored, the system will automatically trigger the model update process.
[0108] The plan generation module automatically generates energy allocation plans for different time periods and under different conditions based on the predicted photovoltaic power generation and power load demand, combined with different preset conditions such as energy prices, grid stability, environmental protection policies, etc.
[0109] The configuration scheme selection module selects the optimal energy configuration scheme from the generated energy allocation plans. This process involves the weighing of multiple factors, such as cost-effectiveness, environmental impact, energy utilization, etc. The system can sort the schemes according to preset priority weights and select the optimal one.
[0110] The energy supply control module controls the energy supply of the energy storage unit of the photovoltaic energy storage system according to the selected energy configuration scheme, which includes adjusting the power generation power of the photovoltaic panels and the charging and discharging strategies of the energy storage batteries.
[0111] The efficiency evaluation and correction module collects the operating data of the photovoltaic energy storage system in real time and evaluates the efficiency level of energy storage, such as energy storage efficiency, energy loss, etc. If the efficiency level is found to be lower than expected, the system will revise the energy allocation plan to improve the efficiency of energy storage.
[0112] The test and solution determination module conducts energy supply tests on the photovoltaic energy storage system through each energy configuration scheme in the revised energy allocation plan. These tests are aimed at verifying the feasibility and effectiveness of the plan.
[0113] After completing the test, the system selects the energy configuration plan with the highest priority weight as the final energy supply execution plan based on the test results. This plan will be passed to the energy supply control module to guide the actual operation of the photovoltaic energy storage system.
