The invention provides a power grid operation state comprehensive evaluation method and device based on big data, and relates to the technical field of power grid evaluation, and the method comprisesthe steps: S1, obtaining a power grid operation state parameter and an external environment parameter; s2, obtaining power grid evaluation parameters based on the power grid operation state parametersand the external environment parameters; and S3, obtaining the weight of each power grid evaluation parameter, and obtaining a power grid comprehensive state evaluation value in combination with thepower grid evaluation parameters. Through the method and the device provided by the invention, the operation state of the power grid can be accurately judged, so that the evaluated value can reach a true value.
Description
technical field [0001] The present invention relates to the technical field of power grid evaluation, in particular to a method for comprehensive evaluation of power grid operating status based on big data. Background technique [0002] With the rapid development of my country's economy, the demand for electricity is increasing, and the power grid is becoming more and more complex. With the access of large-scale distributed power sources, the complexity of the power grid is increasing, and the difficulty of judging the operating status of the power grid is also increasing. This will directly affect To the benefit of the power grid and the quality of electricity used by users, the power grid is required to have higher security and reliability. [0003] With the integration of large-scale distributed new energy into the power grid, the structure of the power grid is becoming more and more complex, and the evaluation and judgment of the operating state of the power grid has beco...
