WebApr 9, 2024 · Firstly, we convert one-dimensional data to a Gramian Angular Field (GAF) image showing a spatial correlation, and add three kinds of noise to the original GAF image to prevent overfitting. Secondly, we propose an Inception-Resnet-V2 model based on the attention mechanism ECANet, which can improve the training effect obviously. WebModel order reduction has been an active field of research in power systems analysis and control design in recent years. Reduced-order models (ROMs) are of interest to provide a better understanding of the involved physical phenomena and can be used for parametric analysis of system behaviour and control interaction analysis. re4 separate ways gamecube
