Abstract

The power load prediction in vessel is an important factor in determining the capacity and number of generators, and in particular the consumption of fuel oil which determines the number of days that can be sailed. In addition, short-term load forecasting is important for the capacity and scheduling of the ESS that will be applied in the future vessel. In this paper, we present a deep stack neural network for short-term load prediction in large vessels. The network is constructed using Convolutional Neural Network (CNN), Bidirectional Long-Short Term Memory (Bi-LSTM), and Long-Short Term Memory (LSTM). CNN is used for spatial feature extraction and Bi-LSTM is used to utilize information at both pre and post stages. Finally, LSTM is used to extract temporal characteristics. The voyage data of the Mokpo National Maritime University training ship was used for the short-term load prediction, and the predicted results are verified by the Mean Squared Error (MSE) and Mean Absolute Error (MAE).
