Multi-energy load short-term forecasting of integrated energy system based on ATT-TCGNN
In an integrated energy system,there are complex and strong coupling relationships between the multi-energy loads,and multi-energy loads have strong volatility and randomness.In view of the above characteristics,a multi-energy load short-term forecasting model based on graph neural network,attention mechanism and variational mode decomposition is proposed.Firstly,the variational mode decomposition of multi-energy loads is carried out to weaken the volatility and randomness.Then through the graph learning network improved by the attention mecha-nism,a graph structure that fully reflects the coupling connection of multi-energy loads and the correlation between multi-energy loads and meteorology is established,and the graph prediction network is used to analyze the graph structure and the historical data of multi-energy loads to realize the prediction of multi-energy loads.Finally,the proposed model is compared with other models based on the actual data of Arizona State University.The results show that the proposed model has higher prediction accuracy.
