Abstract: At present, with the widespread popularity of power facilities and the rapid development of the power grid, a set of research models based on time series improvement has been introduced for the problem of power system load forecasting. This method is based on deep mining analysis of the regularity of the power load itself, mathematically processes the power load forecast in actual operation, draws up parameters based on correlation functions, and transforms into a stable time series for forecasting. The test results show that in the short-term load forecasting, the forecasting result is in good agreement with the actual value, the error is less than 2%, the data is accurate, and it has high reliability and measurement value.
