Real-time acquisition and processing of equipment data, accurate demand forecasting, and effective scheduling strategies have not been fully resolved, which seriously affects the operating efficiency and reliability of virtual power plants. Obtaining high-quality distributed power plant equipment data is the basis for realizing intelligent regulation. Existing systems often face problems of data anomalies and missing data, which makes it difficult to generate complete equipment data, which in turn affects the screening and application of standard operating parameters. In addition, the collaborative operation effect between devices has not been fully explored, resulting in insufficient data accuracy in combined power generation simulation, which cannot provide effective support for power demand. Summary of the invention

[0079] The present invention ensures the comprehensiveness and accuracy of the data basis by acquiring the data of distributed power plant equipment. The processing of replacing outliers on these data can effectively eliminate inaccurate data caused by data acquisition errors or equipment failures, thereby improving the reliability of the overall data. Then, the standard operating parameters are screened for the complete equipment data to ensure that the data used meets the normal operating requirements of the equipment, which is crucial for subsequent analysis and simulation. This standardized processing of data not only improves the availability and consistency of the data, but also lays a solid foundation for subsequent simulation analysis, ensures the effectiveness and accuracy of subsequent steps, and performs equipment unit simulation processing on the standard equipment operating parameters to generate a variety of simulated power plant equipment units. This process enables a variety of equipment combinations to be simulated under different operating conditions, providing a more comprehensive operating perspective. This simulation can not only help identify the synergy between different equipment, but also generate a variety of combined power generation simulation data through combined power generation simulation, providing a rich basis for the dispatching decision of the power plant. Through these simulation data, the operating efficiency of the power plant can be deeply analyzed, the configuration scheme of the equipment can be optimized, thereby improving the flexibility and efficiency of the overall power production, and by acquiring historical power output data and performing power demand analysis, an important foundation is established for the change of power demand. This stage not only involves in-depth analysis of historical data, but also requires extracting the laws and trends of power demand from it in order to make more accurate power output forecasts. Based on these historical data, the power generation demand forecast significantly improves the accuracy of the forecast, which helps the power plant to be fully prepared to cope with future power demand fluctuations. Further demand peak and valley analysis can help identify the peak and valley periods of power demand, which provides an important basis for the subsequent optimization of scheduling strategies, ensuring the stability and reliability of power supply. Based on the analysis of the power output data required for the forecast, the intensity adaptation screening of multiple combined power generation simulation data is carried out to ensure efficient power generation of different equipment combinations under various demand conditions. The implementation of this process can not only improve the adaptability of the equipment combination, but also ensure that the dispatching strategy of the power plant can respond flexibly when facing different power demands. Next, the operation cycle of the power generation intensity adaptation combination unit is adjusted based on the power demand peak and valley data to further optimize the dispatching efficiency of the equipment combination. By reasonably arranging the operation cycle of the equipment, sufficient power output can be provided during the peak period of power demand, and unnecessary energy loss can be reduced during the trough period of demand, thereby achieving efficient utilization of resources. The generated distributed equipment dispatch instructions realize the intelligent management of the virtual power plant. These instructions can dynamically dispatch equipment operations based on real-time data and forecast results, improving the responsiveness and control capabilities of power plants. This process not only promotes coordination between distributed power plants and the power grid, but also enhances the stability and reliability of the entire power system.Driven by intelligent control methods, distributed power plants can more efficiently utilize renewable energy and promote the development and application of green energy. At the same time, by improving the flexibility of power supply, it can better meet the diverse power needs of users, thereby enhancing user satisfaction and optimizing the overall power service quality.

The data format is usually CSV (Comma-Separated Values) or database format. Next, the power demand analysis is performed on the historical power output data. Time series analysis methods, such as ARIMA (Autoregressive Integrated Moving Average model), are used to identify the trend and cyclical changes in power demand to obtain historical power demand data. Based on the historical power demand data, the power generation demand is predicted for the standard equipment operating parameters. Linear regression or machine learning models such as Random Forest are used for prediction to generate the power output data required for the prediction. Subsequently, the demand peak and valley analysis is performed on the power output data required for the prediction. The peak and valley analysis method is used to identify the peaks and valleys of power demand and obtain the peak and valley data of power demand to provide a basis for subsequent scheduling.

[0087] Step S4: Based on the predicted required power output data, multiple combined power generation simulation data are strength-adaptively screened to obtain a power generation strength adaptation combination unit; based on the power demand peak and valley data, the power generation strength adaptation combination unit is operated periodically adjusted to generate adaptation equipment combination scheduling data;

[0098] In this embodiment, the operation of obtaining the distributed power plant equipment data is to collect real-time data from each distributed device by using a data acquisition system. The specific method includes using Modbus protocol or OPC UA (OLE for Process Control Unified Architecture) for data communication to ensure that the data transmission between devices is real-time and accurate. The collected data includes multiple parameters such as voltage, current, power, temperature, etc. Next, the distributed power plant equipment data is detected for abnormal value intervals, and statistical methods such as Z-score detection or box plot (Box Plot) method is used to identify abnormal points in the data, determine the upper and lower limits of abnormal values, generate abnormal value intervals for power plant equipment, and perform abnormal elimination operations on abnormal value intervals for power plant equipment. First, according to the determined abnormal value interval, by writing a data processing script, using Python or R language to implement data filtering, the data that is not in the normal interval is eliminated, and the cleaning power plant equipment data is generated. The specific method includes using the DataFrame in the Pandas library to perform data operations, traversing each data point, determining whether it is within the normal range, and ensuring that valid data is retained. After eliminating abnormal data, the generated data set should contain historical data of each device under normal operating conditions, perform linear interpolation operations on the abnormal interval of the cleaning power plant equipment data, and apply the linear interpolation algorithm to fill in missing or incomplete data. The specific steps are to first identify the location of the missing value in the data set, and then calculate the interpolation based on the valid data points adjacent to the front and back. The interpolation function of the NumPy library is used to perform linear interpolation calculations to generate complete device data and ensure data continuity during the interpolation process.

Then the parameters of the clustering algorithm are set, such as the number of clusters. Then, the standardized data is clustered to generate a clustering operation parameter set. Each cluster represents a group of similar equipment operation states. In the specific implementation, the Python Scikit-learn library is used to cluster the data.Ensure that the clustering results can effectively reflect the operating characteristics of the equipment under different working conditions, and provide a basis for subsequent standardization. The operation of standardizing the clustering operating parameter set uses standardization techniques such as Z-score standardization or Min-Max scaling to unify the clustering results to eliminate the dimensional influence between different characteristics. The specific method is to calculate the mean and standard deviation of each clustering parameter, use the formula for standardization, generate standard equipment operating parameters, ensure that all parameters are on the same scale, and facilitate subsequent analysis and comparison. The final standard equipment operating parameters will provide basic data for equipment performance evaluation and optimization, and ensure the effectiveness of subsequent scheduling and decision-making. ,

It is ensured that a suitable degree of fitting is selected during the fitting process to avoid overfitting or underfitting. The predicted power output curve is then tested for extreme points of the curve. The extreme points of the curve are identified using a derivative method or a second-order derivative method to obtain peak and valley data of power demand. It is ensured that the identified peak and valley data can accurately reflect the peaks and valleys of power demand, provide a scientific basis for the scheduling and resource allocation of power plants, and ensure that reasonable decisions can be made under different power demand conditions.

Then, the NumPy library in Python is used to superimpose the power generation of each combination, and the total power output of each combination in different time periods is calculated to generate combined power data. Next, the combined power data is subjected to stable efficiency calculation, and the efficiency formula is adopted, that is, the efficiency is equal to the ratio of the output power to the input power. The calculation results are sorted using the Pandas library to generate a combined efficiency index to ensure that the efficiency index of each combination can accurately reflect its performance in actual operation, providing a basis for subsequent adaptation and screening. Based on the predicted required power output data, the operation of power generation intensity adaptation screening of the combined efficiency index is performed.

First, the peak and valley data are integrated with the power generation intensity adaptation combination unit. The two are connected according to time series or specific conditions using data framework tools such as Pandas' merge function to generate a peak and valley adaptation equipment unit table to ensure that each combination unit can correspond to the corresponding power demand peak and valley data. Through this association, the operating characteristics of different equipment combinations during peak and valley periods are clarified to provide a basis for subsequent scheduling decisions and ensure the accuracy and real-time nature of the data. Based on the peak and valley adaptation equipment unit table, the operation cycle of the power generation intensity adaptation combination unit is adjusted. First, the operating time and power demand of each combination unit in the peak and valley adaptation equipment unit table are analyzed. Optimization algorithms such as linear programming are used to adjust the operating cycle of the equipment to ensure that during peak power demand periods, high-efficiency equipment combinations can be scheduled first, and adaptive equipment combination scheduling data is generated. Use scheduling management system software such as SCADA (Supervisory The generated dispatch data can be visualized to ensure the rationality and feasibility of the dispatch plan, and finally form a set of efficient equipment combination dispatch strategies to cope with changes in power demand.

[0142] Preferably, step S44 includes the following steps:

[0143] Step S441: performing time series decomposition on the peak-valley adaptation equipment unit table to obtain a basic cycle sequence; performing principal component extraction on the basic cycle sequence to obtain a core cycle pattern;

[0144] Step S442: divide the core cycle mode into time windows to obtain scheduling time segments; perform device state mapping on the power generation intensity adaptation combination unit according to the scheduling time segments to generate a device state sequence;

[0145] Step S443: Calculate the state transition cost of the device state sequence to obtain a state transition matrix;

[0146] Step S444: perform the shortest step length detection on the state transition matrix to generate the shortest path data; perform the equipment operation cycle adjustment on the shortest path data to generate the adaptive equipment combination scheduling data.

[0147] In this embodiment, the operation of time series decomposition of the peak-valley adaptation equipment unit table is first performed by using the statsmodels library in Python to perform seasonal decomposition on the equipment operation data, and an additive or multiplicative model is used to obtain a basic cycle sequence, which includes a trend component, a seasonal component, and a residual component. The next step is to extract the principal component of the basic cycle sequence and use principal component analysis (PCA) to extract the principal component of the basic cycle sequence. Analysis), using the PCA tool in the Scikit-learn library to extract the core cycle pattern that best represents the data variability, ensuring that the extracted principal components can effectively reflect the main characteristics of the equipment's operating status, generating the core cycle pattern, and providing a basis for the subsequent scheduling time segment division. The core cycle pattern is divided into time windows. First, according to the actual needs of the equipment operation and historical data, a reasonable time window length is set. The core cycle pattern is sliced ​​using Python's Pandas library to generate scheduling time segments, ensuring that each time segment can represent a complete equipment operation cycle. Next, the power generation intensity adaptation combination unit is mapped to the equipment state according to the scheduling time segment. Using the mapping algorithm, each time segment is matched with the corresponding equipment state to generate an equipment state sequence, ensuring that the state sequence can truly reflect the equipment's operating status in each time period, providing basic data for the subsequent state transition cost calculation. The state transition cost calculation operation is performed on the equipment state sequence. First, the cost function of the state transition is defined. The cost function can consider factors such as the energy consumption, start and stop time of the equipment, and then build a state transition matrix. Use the NumPy library in Python to count the transitions between the states in the equipment state sequence and generate a state transition matrix to ensure that each element in the matrix can accurately reflect the cost of transitioning from one state to another. After completion, the state transition matrix obtained provides necessary data support for the subsequent shortest step detection. The state transition matrix is ​​subjected to the shortest step detection operation. The state transition matrix is ​​analyzed using the Dijkstra algorithm or the A* algorithm to find the shortest path from the initial state to the target state, ensuring that the algorithm can effectively handle the conversion cost of each state in the matrix and generate the shortest path data. Next, the equipment operation cycle is adjusted according to the obtained shortest path data. The scheduling optimization tool is used to generate the adaptive equipment combination scheduling data by adjusting the equipment operation time and sequence to ensure that the final scheduling plan can maximize the power generation efficiency of the equipment and reduce the operating cost. The obtained scheduling data will provide a scientific basis for the intelligent scheduling of the power plant.

[0148] Preferably, step S443 includes the following steps:

[0149] Performing state quantization processing on the device state sequence to obtain a quantized state sequence;

[0150] Perform transfer frequency statistics on the quantized state sequence to generate a state transfer frequency table;

[0151] Based on the preset state transition weight data, the state transition frequency table is cost calculated to obtain the basic state transition cost; the basic state transition cost is matrix constructed to generate the state transition cost matrix;

[0152] Identify unreasonable costs on the state transfer cost matrix and obtain unreasonable conversion costs;

[0153] The cost branches of the state transfer cost matrix are cleaned up according to the unreasonable conversion costs to generate the state transition matrix.

[0154] In this embodiment, the operation of performing state quantization processing on the device state sequence first classifies the continuous states in the device state sequence, defines the quantization standard for each state, and uses the NumPy library or Pandas library in Python to convert the state sequence into a quantized state sequence to ensure that each state is mapped to a discrete value. Next, the transition frequency of the quantized state sequence is counted, and the groupby function in the Pandas library is used to count the transitions between adjacent states to generate a state transition frequency table, which includes the number of transitions between each state, to ensure that the statistical results can truly reflect the changing patterns of the device state and provide a data basis for subsequent cost calculations. The operation of cost calculation for the state transition frequency table based on the preset state transition weight data first sets the weight data for each state transition. These weights can be set according to the energy consumption, maintenance cost and operating efficiency of the equipment. Then, the frequency in the state transition frequency table is multiplied by the corresponding weight to obtain the basic state transition cost. The Pandas library in Python is used for data processing to ensure that the cost of each state transition can accurately reflect the actual situation. After completion, the basic state transition cost is constructed into a matrix to generate a state transition cost matrix. Each element of the matrix corresponds to the conversion cost between each pair of states in the state transition frequency table, ensuring that the matrix is ​​structured for subsequent analysis. The operation of identifying unreasonable costs for the state transition cost matrix first sets the threshold of reasonable costs. These thresholds can be set based on industry standards or historical equipment data. Then, the NumPy library in Python is used to compare each element in the state transition cost matrix, identify costs that exceed reasonable thresholds, and generate unreasonable conversion costs. Ensure that the identified unreasonable costs can accurately reflect abnormal conditions in equipment operation and provide a basis for subsequent cost cleanup. The cost branch cleaning operation of the state transfer cost matrix is ​​performed according to the unreasonable conversion cost. First, the unreasonable costs identified are analyzed to determine the state transfers that need to be cleaned up. The drop function in the Pandas library is used to remove the unreasonable state transfers from the cost matrix and generate a cleaned state transition matrix to ensure that the cleaned matrix only contains reasonable state transfer costs. The final state transition matrix will provide accurate data support for subsequent scheduling optimization and equipment management, ensuring cost control and efficiency improvement during equipment operation.
