Problems solved by technology
However, the above-mentioned methods often have a single evaluation index, and have certain limitations for specific problems.
The structure of the modern power system is complex, and the evaluation result of a single index is one-sided, which cannot effectively evaluate the importance of each node in the power grid

The invention provides a method for assessing the importance of grid nodes, computer equipment and storage media. The method includes: obtaining grid node information according to grid data information; preprocessing grid node information to obtain training data; and clustering the training data Analyze and process to obtain clustering data; obtain the membership function according to the clustering data; initialize the rule parameters of the membership function to obtain the initialized rule parameters; obtain the power grid according to the membership function and the initialized rule parameters The node evaluation value function, through cluster analysis and processing of the grid node information, and constructs the membership function, thereby constructs the grid node importance evaluation model, thereby obtains the grid node evaluation value function, that is, forms a multi-rule grid node importance evaluation model , in order to realize the comprehensive evaluation of the importance of grid nodes, effectively prevent cascading faults in the grid, ensure the safe and stable operation of the grid, and ensure the economic benefits of grid companies.
Description
technical field [0001] The invention relates to the technical field of energy system applications, in particular to a method for assessing the importance of grid nodes, computer equipment and storage media. Background technique [0002] my country's power grid structure is huge and complex, and the large-scale Internet power system increases the incidence of power outages, and large-scale power outages seriously endanger the safe and stable operation of the power grid, seriously affecting my country's national economic security and social security. The main causes of power outages can be summarized into three aspects: first, internal faults of the power grid system, such as component equipment failures, overloads, communication system failures, system protection failures, etc.; The third is natural factors, such as earthquakes, typhoons, floods, ice disasters and other natural disasters. Large-scale power outages are usually caused by the fault source of the power outage ca...
