Multivariate Load Forecasting of Integrated Energy System Based on CEEMDAN-CSO-LSTM-MTL
Published 2025-01-01“…Firstly,preprocess the collected raw load data and calculate the actual load value considering system energy loss; Secondly,the maximum information coefficient (MIC) is used to analyze the correlation between multiple loads and between multiple loads and weather factors,and to extract strongly correlated variables of multiple loads; Once again,the strongly correlated variables of multiple loads are substituted into CEEMDAN,and the load data is decomposed into stationary subsequences; Then,the feature sequence is substituted into the LSTM-MTL shared layer and the CSO algorithm is used to optimize the prediction model,achieving collaborative prediction of multiple loads; Finally,the performance of the constructed model was validated using a multivariate load dataset from a chemical park in Jilin City,Jilin Province,China. The results show that compared with traditional prediction models,the constructed model can effectively improve the prediction accuracy of multiple loads in the integrated energy system.…”

Long-Term Trends and Ecological Risks of Heavy Metal Accumulation in Cultivated Land of Songnen Plain, China
Published 2025-01-01“…To assess the risks, identify the sources, quantify the amounts, and determine the extent of pollution from seven heavy metals, as well as to provide early warnings, 78 soil samples were collected from farmed lands in the Songnen Plain of Jilin Province. The average concentrations of Zn, Cu, Mn, Pb, Cd, Ni, and As were found to be 2.05, 1.5, 0.2, 1.09, 2.68, 1.53, and 1.17 times higher than the background values of Chinese soils, respectively. …”
