Quality Assessment of Power Dispatching Data Based on Improved Cloud Model

摘要

This paper presents a data quality assessment method based on improved cloud model for the quality assessment of power dispatching data. The cloud model is used to make the soft segmentation of the reviews. The evaluation results are transformed into cloud models by means of the reverse cloud generator, and the corresponding evaluation cloud is constructed. At last, the similarity degree between the comprehensive evaluation cloud and each evaluation grade cloud is calculated by the similarity algorithm based on the improved cloud model, so as to determine the evaluation grade to which the electric power dispatching data belongs. The method of data quality assessment based on improved cloud model is proposed based on the data characteristics and business characteristics of Power Scheduling Center. The evaluation result is fair and objective. And the practicality of the method is verified by the experiment, which compensates the shortcomings of the quality assessment method of power dispatching data.
