摘要
Aiming at the low accuracy problem of short-term power load forecasting caused by the influence of multiple uncertain factors such as weather, temperature and holiday, a short-term power load forecasting model based on an improved Autoformer model is proposed. By changing the pre-processing convention of sequence decomposition, an internal decomposition module of depth model is designed, which extracts the intrinsically complex time series trend of hidden state in the model, and makes the model have the ability to decompose complex time series asymptotically. The Nystrom self-Attention mechanism is proposed, which uses the Nystrom method to approximate the standard self-Attention mechanism. The experimental results of power load forecasting in a region show that the proposed model has lower time complexity and higher accuracy than the standard Autoformer model. © 2024 Electric Power Automation Equipment Press.
