Power market data analysis method, system and equipment based on data quality

The invention provides an electricity market data analysis method, system and equipment based on data quality, and relates to the field of electricity market data analysis. The method comprises the following steps: collecting and preprocessing electricity market data to generate preprocessed electricity market data; performing quality evaluation on the preprocessed electricity market data by using a data quality evaluation model, generating a data quality score, and judging whether the preprocessed electricity market data meets requirements or not; repairing the power market data which does not meet the requirements and performing quality evaluation to generate a new data quality score; taking the new data quality score as a data quality score, taking the restored electricity market data as electricity market data for preprocessing, and returning to the judgment step; and when the restored power market data meets the requirements, analyzing and mining the restored power market data, extracting useful features
