At the same time, the peak load regulation of power grid systems has also become an important challenge for power grid system management. However, traditional power grid peak regulation methods are limited by insufficient data, low efficiency, and the inability to meet the target power requirements of multi-grid power supply load peak regulation. Summary of the invention

[0003] Based on this, it is necessary for the present invention to provide an optimization configuration method and system for multi-grid peak regulation based on big data to solve at least one of the above technical problems.

[0004] To achieve the above purpose, an optimization configuration method for multi-grid peak load regulation based on big data includes the following steps:

[0005] Step S1: Perform grid node labeling analysis on the grid system to obtain multiple grid system nodes; perform big data analysis on the multiple grid system nodes to obtain multiple grid energy production status data and multiple grid power transmission line status data; perform power supply load analysis on the grid system based on the multiple grid energy production status data and the multiple grid power transmission line status data to obtain multiple grid power supply load data;

[0006] Step S2: performing a time sequence peak load regulation operation analysis on the nodes of the multi-grid system according to the multi-grid power supply load data to obtain a multi-grid power supply load peak load regulation operation distribution diagram;

[0007] Step S3: Performing operation abnormality analysis on the peak load regulation operation distribution diagram of the power supply loads of multiple power grids to obtain operation abnormality data of the power supply loads of multiple power grids; performing frequency conversion analysis on the operation abnormality data of the power supply loads of multiple power grids to obtain abnormal frequency data of the power supply loads of multiple power grids;

[0008] Step S4: Based on the abnormal frequency data of the power supply loads of the multiple power grids, a frequency regulation optimization configuration analysis is performed on the peak-shaving operation distribution diagram of the power supply loads of the multiple power grids to obtain the peak-shaving optimization configuration data of the power supply loads of the multiple power grids.

[0009] The present invention firstly analyzes the grid node marking of the grid system. The importance of this step is that the accurate marking of the grid nodes can lay the foundation for the subsequent big data analysis process. Obtaining accurate node information is the premise for the management and optimization of the grid system, which can realize the clear description of the structure of multiple grid systems and effectively improve the stability and reliability of the grid system. By performing big data analysis on the nodes of multiple grid systems, the energy production capacity of each grid system and the transmission of electricity in the grid system can be understood, which greatly improves the scope of data, thereby obtaining rich energy production and power transmission line data, which not only provides a deep understanding of the topological structure of the grid system, but also provides a comprehensive and reliable basis for the subsequent power supply load analysis. At the same time, by analyzing the power supply load of the grid system according to the energy production status data of multiple grids and the power transmission line status data of multiple grids, the load situation of the grid system can be fully understood, including the power supply demand of each node and the overall load situation of the system, which provides important data support for grid planning and scheduling, and can also accurately grasp the power supply load characteristics of multiple grids, and provide necessary input for the subsequent peak load operation analysis. Secondly, by analyzing the time-sequential peak-shaving operation of the nodes of the multi-grid system according to the power supply load data of multiple power grids, it is possible to understand the power supply load distribution of the power grid system in different time periods, which is helpful to more reasonably allocate power resources during the peak period of power supply load, improve the dispatching efficiency and operation stability of the power grid system, and thus form a multi-grid power supply load peak-shaving operation distribution map.

Then, by performing an operation abnormality analysis on the multi-grid power supply load peak-shaving operation distribution map, potential problems and abnormal conditions can be identified early. And by analyzing the abnormal operation data of the multi-grid power supply load, the nature and impact of abnormal events can be deeply understood. Furthermore, frequency conversion analysis helps to convert abnormal data into frequency domain information and provide accurate cognition of abnormal frequencies, which provides strong data support for the system to deal with abnormal conditions and lays the foundation for the next step of frequency optimization configuration analysis. Finally, by performing frequency optimization configuration analysis on the multi-grid power supply load peak-shaving operation distribution map based on the abnormal frequency data of the multi-grid power supply load, the peak-shaving operation performance of the power grid system under abnormal frequency conditions can be improved. By fine-tuning the abnormal frequency parameters of the system, it is possible to respond more flexibly to abnormal frequency fluctuations, ensuring that the power grid system can maintain efficient and stable operation under various circumstances, thereby providing specific peak-shaving optimization suggestions for the power grid system and making the power grid system more adaptable to the changing peak-shaving power requirements of the power supply load.

[0028] In the embodiment of the present invention, please refer to Figure 1 As shown, it is a schematic flow chart of the steps of the optimization configuration method based on big data multi-grid peak regulation of the present invention. In this example, the steps of the optimization configuration method based on big data multi-grid peak regulation include:

[0029] Step S1: Perform grid node labeling analysis on the grid system to obtain multiple grid system nodes; perform big data analysis on the multiple grid system nodes to obtain multiple grid energy production status data and multiple grid power transmission line status data; perform power supply load analysis on the grid system based on the multiple grid energy production status data and the multiple grid power transmission line status data to obtain multiple grid power supply load data;

[0030] The embodiment of the present invention analyzes the power grid system by using topological analysis technology to determine the interconnection relationship between the components of multiple power grid systems, forms a power grid system topology, and identifies each node in the power grid system, including power stations, substations, etc., by marking nodes on the analyzed power grid system topology, thereby obtaining multiple power grid system nodes. Then, by using corresponding sensors to collect energy production data of each multi-grid system node, including information such as power generation, power generation mode, energy type, and specific power transmission channel conditions between each multi-grid system node, and by using big data analysis methods to analyze the collected data to determine the energy production status of each node, including the power generation of various energy production equipment, the status of energy storage equipment, etc., and detect and evaluate the power transmission status between each multi-grid system node, including line capacity, impedance, voltage, etc., thereby obtaining multi-grid energy production status data and multi-grid power transmission line status data. Finally, by analyzing the power grid system according to the multi-grid energy production status data and multi-grid power transmission line status data obtained by analysis, the load status of the power grid system is fully understood, and finally the multi-grid power supply load data is obtained.

The acquisition of this value helps the system plan the capacity of peak load measures and improves the flexibility of the system to deal with abnormal loads. Then, by using the frequency optimization objective function based on the abnormal power adjustment capacity value of the power supply load of multiple power grids obtained by analysis, the peak load operation distribution diagram of the power supply load of multiple power grids is optimized by frequency modulation, and intelligent adjustment can be performed according to specific power adjustment requirements. The core of this step is to achieve the reasonable allocation of abnormal power through the frequency modulation optimization objective function to ensure that the power grid system can still maintain a stable operating state under abnormal conditions, thereby obtaining the multi-grid power supply load frequency modulation optimization distribution map, which can provide the power grid system with an intuitive image of the frequency modulation optimization solution, and help engineers and operators better understand the peak-shaving operation status of the power grid system. Finally, by optimizing the configuration analysis of the multi-grid power supply load frequency modulation optimization distribution map, the frequency modulation optimization results can be deeply studied to find the optimal configuration solution. By analyzing the multi-grid power supply load frequency modulation optimization distribution map, the optimal configuration parameters can be determined to achieve the best performance of the power grid system peak-shaving under abnormal conditions, thereby providing specific configuration suggestions for the power grid system, which helps to optimize the system operation efficiency and improve the peak-shaving performance.
