Abstract To improve the forcasting accuracy of short and medium term loads, this article proposes an autoregressive moving average model based on Markov residual correction. The autoregressive moving average model is used to predict the load and calculate the residual, and the Markov residual correction algorithm is used to correct the prediction results. The engineering case verification shows that the average absolute error of load forecasting obtained by the autoregressive moving average model is 13.67%. After Markov residual correction, the average absolute error of load forecasting is 6.912%, and the prediction accuracy is improved by 49.4%. It is concluded that the load forecasting model proposed in this article has certain significance for guiding industrial users in short and medium term loads forecasting.
