A Reliable Short‐Term Power Load Forecasting Method Based on VMD‐IWOA‐LSTM Algorithm

Abstract: To reduce the short-term load forecasting (STLF) error of off-line forecasting model, a VMD-IWOA-LSTM (VIL) method for STLF is proposed. Firstly, variational mode decomposition (VMD) is used to decompose the historical power load signals. Then, the decomposed signals are reconstructed according to the similarity of Pearson correlation coefficient (PCC), and meteorological data are chosen for each reconstructed component based on the set PCC threshold. The long short-term memory (LSTM) models are used to predic… Show more

“…The water source of Ha Cai Tou Dang has a moderate continental monsoon climate, characterized by average annual temperatures ranging from 6.0 to 8.5 • C, precipitation levels of 220-400 mm, evaporation rates of 2100-2600 mm, and an average annual wind speed of 4.5 m/s. The climate of the Ha Cai Tou Dang water source area is characterized by significant evaporation, a fluctuating distribution of precipitation, intense solar radiation, windy and sandy conditions, and aridity [29].…”

“…While the secondary decomposition method can further refine the data and optimize the prediction model, most current studies are still limited to the primary decomposition, which results in residual components that still contain a significant amount of non-stationarity despite the decomposition technique's effectiveness in reducing non-stationarity and complexity of the data [28]. However, the decomposed characteristics of the current quadratic decomposition models are not thoroughly analyzed, which results in inadequate information extraction and lowers prediction accuracy [29]. Our goal is to improve these decomposition techniques so that vegetation change may be predicted with greater accuracy.…”

“…Digital networking consists of two parts: network digitization in physical space and network intelligence in digital space. Both the State Plan and China Southern Energy have begun developing digital energy plans and have made some progress [1] . Digital Twin (DT) is the core of digital networking technology, but its definition continues to evolve.…”
